    DK 2019 70286 A1 Adapter, lifting device, lifting system and method and use thereof The present invention relates to an adapter for fastening in a lifting element for use in a lifting system with a lifting device for hooking and handling concrete elements.
    The invention also relates to a lifting device for gripping - at least indirectly - in a sling element for use in a lifting system for slinging and handling concrete elements.
    The invention further relates to a lifting system for attaching and handling concrete elements.
    Finally, the invention relates to a method as well as an application of the lifting system.
    Prior art It is now generally known that concrete elements for house construction are manufactured as building blocks that are assembled into finished buildings.
    These are often very large building blocks and they are handled with lifting equipment in production, when they are moved from production to warehouse, when they are loaded on cars, when they are unloaded from cars and when they are built together on the construction sites to become the buildings they are made for. .
    > DK 2019 70286 A1 The concrete elements are therefore manufactured with attachment elements - so that hooks, shackles or special couplings can be attached to the attachment element that is now used. This fastening and subsequent removal of hooks, shackles or special couplings - is manual. Concrete wall elements are often stored standing with the attachment element located on the side of the concrete wall element facing upwards - ie on the short surface on top of the element, and therefore removal of hooks, shackles or special couplings usually takes place from the ladder. Perforated tires made with an extruder in a continuous process - in long paths - also have the cutting elements located on the side of the element facing upwards - for perforated tires, it is the largest or widest surface that thus becomes the top of the element. Four attachment elements (ball head anchors) are placed in all hollow decks for later handling. After softening in the extruder, the lifting device is mounted manually in the attachment element and the hollow core is moved and subsequently stored in stacks. The suction from the extruder takes place at table height and is safe in terms of safety, but during the disconnection the hole decks can be located at a height of 3 meters and therefore require a ladder for a crane operator to reach up and disconnect the hole deck. A similar problem applies to TT / TTD elements as to hollow core tires.
    Cutting elements come in two types:
    2 DK 2019 70286 A1
    1. Anchoring elements that protrude from the surface, but typically require removal when the concrete element is mounted on the construction site, as the attachment elements are in the way of a joint with an adjacent concrete element.
    2. Anchoring elements that do NOT protrude from the surface - but are submerged to NOT get in the way when the concrete elements are assembled. Traditionally, concrete element factories choose type 2 attachment elements - where the attachment element is submerged - as there is no need to remove attachment elements on the construction site, an operation that often takes place from a ladder or from a passenger lift. Removal of type 1 cutting elements protruding from the surface often involves cutting - which generates chips and discolors the concrete elements when these chips rust. Type 2 attachment elements today require manual handling and attachment to the attachment element from ladder - in all stages of the logistics.
    It is critical from a safety point of view and extremely resource-intensive - both at the element factory, when loading, when unloading and when removing attachment elements when the concrete element is mounted on the construction site.
    The object of the invention is therefore the object of the invention to provide a solution for type 2 attachment elements - a solution which can remove the safety risks associated with work on ladders and reduce the resource consumption when handling in general.
    1 DK 2019 70286 A1 It is a further object of the invention to provide a solution where a single crane operator can handle the concrete elements directly from the ground - without the use of a ladder or lift.
    It is a further object of the invention that the lifting device can be disconnected from a sling element by means of an actuator directly from the crane control and from floor level at a safe distance from the concrete element. Additional objects of the invention are:. Great safety when mounting the adapter, as this is done manually.
    . Much easier to see and thus hit the adapter with the lifting device.
    . The lifting system cannot be loosened as long as there is a load, ie as long as the concrete element hangs in the lifting system.
    15. Automatic connection / disconnection of adapter (no need for ladder). No problems with ice / snow - provided that the adapter is attached to the submerged attachment element during storage of the concrete element.
    20. Possibility to use the same lifting system for different anchor types.
    Description of the invention According to a first aspect of the invention, the above object is achieved with an adapter as initially described and as described in the preamble of claim 1, wherein the adapter comprises a first end with fastening means for fastening in a sling element and a second end with guide and cooperating means for guiding and cooperating with a lifting device, wherein between the first end and the second end there is a lifting edge intended for the claws of a lifting device.
    on DK 2019 70286 A1 This makes it possible to place an adapter in the attachment element, where the design of the fastening means for fastening in the attachment element depends on the individual anchor placed in the concrete element and where the anchor constitutes the attachment element, where the design of the fastening means depends on the external dimension , which fits into the recess around the anchor of the attachment element. The adapter is made for a specific attachment element (ball head anchors, hollow anchors, etc.) - but always has the same external design, so the lifting device will always be able to grip and cooperate with the adapter. There is great safety when mounting the adapter, as the mounting is done manually, just as it is much easier to see and thus hit the adapter with the lifting device, as the adapter protrudes above the cast surfaces of the concrete elements and only protrudes where the sling elements are located. In addition, there are no problems with ice / snow - provided that the adapter is attached to the submerged attachment element during storage of the concrete element.
    In a further aspect, the present invention also relates to an adapter, wherein the means and guides of the other end comprise a conical shape tapered in the direction from the first end towards the second end, the conical shape being substantially congruent with the conical shape of the lifting device.
    This makes it possible to ensure that the lifting device can be more easily controlled in place and engage with the adapter, as the clearance at the beginning of the engagement phase is relatively large, while the clearance due to the shape of the cone becomes smaller and smaller until the lifting device is fully controlled.
    . The present invention also relates in a further aspect also to an adapter, wherein the adapter comprises two adapter elements, preferably two halves which together form an adapter, and wherein the adapter elements comprise interconnecting means for interconnecting the adapter elements.
    This makes it possible to provide an adapter where the adapter elements are connected and possibly are hinged or adapter elements which as two separate halves can be separated / assembled by means of magnets or other connecting means.
    In a further aspect, the present invention also relates to an adapter, wherein the lifting edge of the adapter comprises a recess in the direction from the first end towards the second end of the adapter.
    This makes it possible to ensure that the claws of the lifting device cannot be released and detached from the adapter during lifting and as long as there is a load on the claws, ie as long as the concrete element hangs in the lifting system, the recess preferably being like a ring around the adapter .
    According to a further aspect of the invention, the above object is achieved with a lifting device for gripping - at least indirectly - in a lifting element for use in a lifting system for gripping and handling concrete elements, wherein the lifting device comprises a first end with control and cooperating means for control. and cooperating with an adapter, one end for attachment to a crane yoke, an inner side intended for control and cooperating means for guiding and cooperating with the control and cooperating means of an adapter, an outer side comprising a sheath movable between a position in direction of the first end, where claws intended to engage with one of: adapter, attachment element are locked and a position towards the second end, where the claws are released and where the casing of the lifting device is moved by means of an actuator.
    , DK 2019 70286 A1 By at least indirectly it is meant that in certain situations it can be done well directly, ie to grip the attachment element directly without the use of an adapter. Here the claws are adapted to the attachment element and grab this directly. This makes it possible to use a lifting device for gripping, for example with hollow core tires made with an extruder in a continuous process - in long lanes, - where the attachment elements are mounted in the surface. In hollow decks, four attachment elements (ball head anchors) are placed for later handling. After softening in the extruder, the lifting device is mounted manually in the attachment element and the hollow core is moved out and stored in stacks. The cutting from the extruder takes place at table height and is safe in terms of safety.
    The claws of the claw are adapted to the attachment element of the concrete element, i.e. the anchor embedded in the concrete element, so that the claws can grip it directly. By claw is meant a construction preferably comprising three claws or four claws.
    During uncoupling, however, the tires may be located at a height of 3 meters and require a ladder to reach. Here, the lifting device is a huge benefit, as it can be disconnected from the sling element using the actuator directly from the crane control and from floor level at a safe distance to the hollow deck, with which a single crane operator can handle the concrete elements directly from the ground - without using a ladder or lift. If the gripping is carried out in the attachment element using an adapter, the lifting device thus grips the adapter directly. This also makes it possible to use a lifting device for gripping concrete weighing elements, where the attachment elements are mounted submerged in the surface. The lifting device
    0 DK 2019 70286 A1 can here be disconnected from an adapter by means of an actuator directly from the crane control and from floor level at a safe distance from the concrete element. The lifting device will typically be attached to a crane yoke and controlled manually with the crane up to the adapter, after which the lifting device - which in a preferred embodiment has four claws - can be lowered over the adapter, after which the lifting device is coupled and locked on the adapter. used to lift the concrete element with.
    When the lifting is completed, the lifting device can be released with the same actuator and disconnected from the adapter, thus removing the safety risks associated with working on ladders, as well as reducing resource consumption during handling in general.
    The lifting device can be placed on crane yokes of different configurations - for handling different concrete elements. They can be connected in pairs or more - depending on the design of the concrete elements.
    The actuator makes it possible to move the casing, where the actuator in a preferred embodiment is an electric actuator, in an alternative embodiment pneumatic or hydraulic actuator.
    The present invention also relates in a further aspect also to a lifting device, wherein the inside of the lifting device, which is intended to cooperate with the control and cooperating means of an adapter, comprises a conical shape tapered in the direction from the first end towards the second end, the conical shape being in the essentially congruent with the conical shape of an adapter.
    This makes it possible to ensure that the lifting device can be more easily controlled in place and engage the adapter in cases where an adapter is used.
    The present invention also relates in a further aspect also to a lifting device, wherein the claws are provided with a rounded projection intended for engagement with an adapter lifting edge, where the projection during the locking of the claws is directed towards the other end of the lifting device.
    This makes it possible to ensure that the claws of the lifting device cannot be released from the adapter during lifting and loading, as the rounded projections of the claws - in a preferred embodiment - engage with the adapter - so that the claws can NOT open when loaded. This ensures that the load is not lost by accidentally activating the sliding casing. In a further aspect, the present invention also relates to a lifting device, wherein the claws of the lifting device are arranged between the inside and the outside of the lifting device, wherein the claws are spring-actuated via at least one spring.
    This makes it possible to ensure that the spring that affects the claws of the claw and will try to open the claw, ie to get it out of engagement with an adapter or a clamping element, however, can only do this when the sheath is moved in a position in the direction of the other end where the claws are released. The springs are placed between the individual claws and the base the claws are attached to and ensures that the claws are open when the sheath that closes the claws around the adapter or attachment element - is pulled away from the claws. In a preferred embodiment, the spring will be a leaf spring to reduce the installation dimensions, but in principle other spring types could also be used. In a further aspect, the present invention also relates to a lifting device, wherein the lifting device, the other end of which is intended for attachment to a crane yoke, is supplied with energy from the crane yoke to the actuator, which is operated via the lifting control or a separate remote control.
    10 DK 2019 70286 A1 This makes it possible to supply energy to the actuator in an easy and simple way, as there is already an energy supply to the crane yoke. In a further aspect, the present invention also relates to a lifting device, wherein the lifting device comprises a safety circuit which signals that the concrete element should not be lifted when the lifting device is not securely connected and mechanically secured. The lifting device detects with a capacitive sensor in the center of the lifting device whether there is an adapter in the lifting device - whether the actuator is open or closed and thus confirms whether it is possible to lift via a simple control and a signal lamp per lifting device. This makes it possible to ensure that not only one side of an element is lifted - with the risk of the element tipping over. | a preferred embodiment, the control sits on the yoke used to lift the elements and provides a light signal informing the operator whether to lift or not.
    The signal can also be transmitted to the crane and connected to its control. The same safety circuit shows that the adapter is not disconnected when the actuator is opened and needs to be lifted.
    In a further aspect, the present invention also relates to a lifting device, wherein the inside of the lifting device, which is intended to cooperate with the control and cooperating means of an adapter, comprises a sensor intended to detect whether the lifting device is engaged with the adapter.
    1 DK 2019 70286 A1 This makes it possible to register whether there is an adapter in the lifting device, as the sensor located at the bottom of the lifting device detects whether the lifting device is in engagement with the adapter and together with the location of the cover ensures that no lifting takes place without the lifting device is fixed or has released the adapter. In a further aspect, the present invention also relates to a lifting device, wherein the lifting device further comprises a spring-loaded guide. This makes it possible to steer the lifting device to the correct position in relation to the hooking element of the concrete element. In a further aspect, the present invention also relates to a lifting device, wherein the lifting device can furthermore be provided with at least one of the following: video, light. This makes it possible to add elements such as video and light as well as additional distance meters in the form of, for example, sensors to the lifting device, on which they can be mounted as desired and needed.
    The lifting device equipped with video makes it easier to control the crane yoke and the position and connection of the lifting device on the adapter. According to a further aspect of the invention, the above object is achieved with a lifting system as initially described, wherein the lifting system comprises at least one lifting device. This makes it possible to use the lifting system for attaching and handling concrete elements with submerged attachment elements - by a single operator, at a safe distance and from floor level.
    12 DK 2019 70286 A1 This also makes it possible to use the lifting system for use with, for example, hollow decks and TT / TTD concrete elements.
    In a further aspect, the present invention also relates to a lifting system, the lifting system further comprising an adapter.
    This makes it possible to use the lifting system comprising an adapter and a lifting device which grips the adapter, where the adapter is attached to the anchoring element and can follow the concrete element from the production to the final destination of the concrete element.
    This thus makes it possible to also use the lifting system for use on concrete wall elements, which are stored standing with attachment elements located on the side of the element facing upwards - ie on the short surface on top of the element.
    The lifting device typically hangs in a crane yoke with two lifting devices, which are first placed over adapter 1, controlled downwards, after which the operator activates (closes) the actuator on lifting device 1 from the crane control and locks lifting device 1 on adapter 1. Then the operator places lifting device 2 over adapter 2. controls this down over it - after which the operator activates (closes) the actuator on lifting device 2 from the crane control and locks lifting device 2 on adapter 2. With a positive signal from both lifting devices - the element can be lifted.
    When disconnected, the element is placed on the ground and when both lifting devices are relieved, the actuators can be activated (opened) and both lifting devices can be released from the adapters.
    The invention is also directed to a method for using a lifting system, wherein the method basically and at least comprises a step a): the lifting device engages in the sling element. In addition, the invention is directed
    12 DK 2019 70286 A1 against a method which before step a) at least comprises step b): wherein an adapter is fastened in the sling element.
    The invention is also directed to the use of a lifting system for concrete elements, including hollow core slabs and TT / TTD elements stored horizontally with attachment elements located on the side of the element facing upwards as well as concrete wall elements stored upright with attachment elements located on the side of the element. , facing upwards.
    In addition, the invention is directed to a use of a lifting system, where the concrete elements preferably comprise ball head anchors, hollow anchors. TT and TTD elements are prestressed floors and roof elements for buildings with large spans.
    Ball head anchors are a nail-like element that is cast into the concrete elements to lift them. Hole anchor is an anchor that is cast in as the ball head anchor - but with a hole at the end through which a special hook can be put.
