Support arrangement for a basket for manlift The field of the invention
The present invention relates to a support arrangement for a basket for manlifting comprising a lift intended for mounting on a vehicle, which support arrangement comprises a curve support on which the curve is mounted, a support profile on which the curve support is mounted, a rotator and a bracket. , on which the support profile is mounted, the bracket mounted on the outer boom of the lift.
BACKGROUND OF THE INVENTION
A crew lift is often used for smaller maintenance work where it is impossible to set up a scaffold and where it is not justifiable to use a ladder.
Lifts are built in many different ways.
Male lifts can be of different types, such as scissor lifts, toe lifts, telescopic lifts and mobile lifts. Man-made lifts are typically mounted on compact, lightweight vehicles capable of reaching the places where other lifting vehicles are too large and heavy to access. The present invention has been developed in connection with mobile lifts.
Mobile lifts are a lift with a basket for 1-3 persons to do work at height. The lift is mounted on a truck, van, box van or trailer. The larger models often reach 10-50 m upwards. The basket is typically a structure with a rectangular base and therefrom projecting support walls or support railings.
A lift, which is the basic element of the mobile lift, can move in three dimensions, which means that the vehicle rarely has to be moved during work.
The lift comprises a number of mutually pivotally connected booms. A further tea boom in the lift is connected to the swivel gear which enables rotation of the lift about a vertical axis, the Swivel gear / bearing is arranged between the pedestal and the lift.
The curve for people who have to do work at height is linked to an extreme boom in the lift.
The lift will thus comprise at least two mutually swingable booms. The booms are pivotable about horizontally oriented axes so that the pivoting of the booms establishes a raising and lowering of the curve.
The outer boom, which in professional terms is called a fly boom, is designed as a parallelogram to displace the console and thus the curve with a parallel offset which ensures that the bottom of the curve remains largely horizontal during its movement. The lift may be equipped with sensors or guides to ensure the parallel displacement.
The booms can be fixed length fixed or include telescopically displaceable booms which contribute to the Oee range.
The booms are constructed of high strength steel. The lift's electro-hydraulic control can have several automated functions.
The basket is supported on the boom by a support arrangement. This includes a curve support in the form of a cross, a frame, an H-profile or the like for establishing a fastener to areas near the corners of the curve. In the following application, in the present application, by the term "curve support" is meant a support structure which supports the curve regardless of the shape thereof. The support arrangement further comprises a support profile on which the curve support is mounted and which is connected to the outer boom via a bracket unit.
The curve is thus connected to the outer boom so that it is pivoted along with it, and is located at a distance from the outer boom, which is determined by the size and shape of the bracket and the support profile.
It is desired to be able to rotate or rotate the curve about a vertical axis of rotation, so that it is possible to orient the curve independently of the rotation of the booms. This is desirable in certain work situations. For example, if a vehicle holds close by and drives along a wall or similar where work must be carried out at height. Here, there may be a desire for a certain of the sides of the basket to face the workplace. Thus, the support arrangement may comprise a so-called rotator which allows the basket to rotate sideways relative to the outer boom.
However, there will be a risk that the curve will carbolize with the outer boom during rotation. This risk is particularly pronounced when the outer boom is made as a parallelogram, since in this construction guide rods are arranged on each side of a main profile to establish the parallel offset. This wide construction limits the ability to rotate the curve.
Alternatively, the basket may be mounted on a rotator comprising a long support profile. Now, the basket can be pivoted by a large radius to free it from the outer boom. However, this provides a space-intensive construction, with the basket located far from the outer boom.
The object of the invention
It is the object of the present invention to alleviate this disadvantage and enable a great deal of freedom to rotate the curve relative to the outer boom.
According to a further aspect, it is desirable that the operation of the curve is done in a simple manner without the risk of malfunction.
Description of the Invention
This is achieved according to the present invention with a support arrangement of the type mentioned initially, which is characterized in that the curve support is slidably mounted along the support profile and that the support profile is mounted on the bracket for a rotation about a vertical axis and that the supporting arrangement comprises moving means. , which is arranged to establish the displacement of the curve support along the support profile and the oscillation of the support profile relative to the console.
The basket may be positioned close to the outer boom when it is in its initial position and where the work to be performed does not require turning the basket. When there is a need to turn the curve relative to the outer boom, this can be done to a post positioned at an angle of 90 ° to each side relative to the starting position of the curve.
In this way, the wall of the basket - in a rectangular basket - at the farthest from the outer boom can be placed parallel to the plane where the boom booms swing. This can be done without the risk of the basket caramboling with the outer boom.
The displacement of the curve support establishes a distance between the wall of the basket closest to the outer boom and the outer boom, so that the wall of the curve closest to the outer boom can be pivoted and placed outside the outer boom, even in a situation where this outer boom has a considerable width.
It is possible to vary the curve support and thus the curve displacement along the support profile depending on the width of the outer boom. This allows the basket to be placed at a desired distance from the outer boom. According to one embodiment, the support arrangement according to the invention is characterized in that the moving means are arranged to establish a simultaneous displacement of the curve support along the support profile and the swing of the support profile relative to the bracket.
Hereby, a technically simple and effective solution is established, in which it is possible for an operator to activate the moving means and thereby achieve a safe oscillation of the curve without the need for an operator to coordinate individual movements in the form of the displacement and the oscillation. This avoids the risk of malfunctioning.
According to a further embodiment, the support arrangement according to the invention is characterized in that the moving means comprise a first toothed ring fixedly connected to the support profile, a cooperating second toothed ring rotatably mounted in a bearing in the bracket and which at a distance from its axis of rotation via a rotary connection. is connected to a link arm connected to the curve support.
Since the articulation arm is connected to the second dental ring at a distance from its axis of rotation, a rotation will cause a displacement of curve support and thus also the curve, while the engagement between the two dental rings causes a swing of the support profile and thus also the curve.
The rotational connection between the other dental ring and the articulation arm will mean that the curve support can be displaced along the support profile. The rotary joint may be established by means of a pin and a bushing.
According to a further embodiment, the support arrangement according to the invention is characterized in that the second dental ring comprises an extension extending beyond the diameter of the dental ring and that the articulated arm is connected to a distal end of the articulated arm.
By extension, it is possible to increase the radius of rotation of the rotary joint and thus increase the magnitude of the displacement established in relation to a rotational radius of the rotational joint which lies within the dental ring. Thus, it is easy to adjust a displacement relative to a rotation angle of the curve. The extension may be interchangeable or alternatively be provided with multiple bushings which cooperate with a pin on the articulation arm.
According to a further embodiment, the support arrangement according to the invention is characterized in that the curve support is provided with guide shoes which cooperate with the support profile.
The support profile is made of a square profile tube. This may preferably be provided with sliding rails which cooperate with the sliding shoes of the curve support.
This creates a safe guide of the displacement and a suitable low friction between the curve support and the support profile.
According to a further embodiment, the support arrangement according to the invention is characterized in that an actuator is preferably arranged within the support profile, preferably a hydraulic cylinder, which forms part of the moving means, which, upon actuation, establishes for the firing of the curve support along the support profile and the oscillation of the support profile in relation to to the console.
With the actuator arranged in the support profile, a compact construction is obtained. Technically, a protection of the actuator against shock and impact has been established. The support profile, which is a solid structure, constitutes a covering of the actuator.
According to a further embodiment, the support arrangement according to the invention is characterized in that the actuator is rotatably mounted at one end with respect to the support profile and at its other end is connected to a pivot arm arrangement mounted on the first dental ring and on the bracket, so that a extending or shortening the actuator, respectively, causes a swing of the support profile in one and the other direction.
The pivot arm arrangement is arranged so that it rotates about a axis of rotation set relative to the axis of rotation of the first dental crown. A first swing arm connected to the actuator and a second swing arm connected to the first dental ring are arranged. The connection between the second pivot arm and the first dental ring is established by a rotational joint which is also set relative to the axis of rotation of the first dental ring.
The rotary joint is preferably provided on an extension at a radius outside the diameter of the tooth rim, thereby establishing a torque arm so that the power requirement for oscillation of the curve can be kept low. The extension makes it possible to increase the radius of rotation of the rotary joint, thereby reducing the amount of force required to establish the oscillation.

FIG. 1 shows a vehicle mounted on a basket for a manlift,
FIG. 2-7 partial views of a man lift with a basket supported on an outer boom via a support arrangement according to the invention, with the basket shown in different positions,
FIG. 8-12 are top views of a support arrangement (for the basket omitted for the sake of clarity) according to the invention and shown in different positions; Figures 13-17 show support arrangements according to the invention with parts partially transparent to illustrate the different parts of the support arrangement in different positions of the support arrangement, and
FIG. 18 shows an exploded view of a support arrangement according to the invention. DETAILED DESCRIPTION OF THE INVENTION In the following, identical details will be denoted by the same reference numerals throughout all figures. No specific explanation will be given for each figure.
FIG. 1 shows a crew lift 1 comprising a lift 2 which supports a basket 3. The lift 2 is intended for mounting on a vehicle 4 and comprises a swivel 5 which is connected to the vehicle 4 and which allows a rotation of the crew lift 1 about a vertical axis 6.
The lift comprises a lower boom 7 and an outer boom 8 which are pivotally interconnected at a connecting link 9. The lower boom 7 comprises an outer profile 10 and an inner profile 11 telescopically slidable in the outer profile 10. The lower boom 7 is mounted on the swivel 5 via a bracket 12 which allows the lower boom to swing in a vertical plane corresponding to the paper plane of FIG. 1. In this plane also the outer boom 8 can swing relative to the lower boom 7,
The outer boom is provided with a bracket 13 which forms part of a support arrangement 14 (see Fig. 18), with which the curve 3 is connected to the lift 2. This will be explained in more detail below.
FIG. 18 shows an embodiment of the supporting arrangement 14 according to the invention. The support arrangement comprises the bracket 13 which is connected to the outer boom 8. A slave cylinder 15 is provided to ensure that the basket is held with its base 16 (see Fig. 1) in a horizontal orientation by raising and lowering the basket.
The support arrangement comprises a curve support 17, Ϊ in the form shown, the curve support is provided as a cross, where there are established connection points 18 intended for positioning the basket in position and near the corners of the curve. Curve support 17 has a central portion 19 in which sliding shoes 20 are mounted.
The support arrangement further comprises a support profile 21 provided as a hollow square tube in which an actuator 22 in the form of a two-way hydraulic cylinder is pivotally mounted about a pin 23 passing through a bushing 24 on the actuator.
At its other end, the actuator 22 is connected to a pivot arm arrangement 25. The connection is established via a pin 26 passing through a sleeve 27 for a mutual rotation.
The swingarm arrangement 25 is mounted in a mounting bracket 28 mounted in the bracket 13.
The support profile 21 comprises sliding rails 29 which cooperate with the sliding shoes 20 for a slight displacement of the curve support and thus the curve along the support profile 21.
The support arrangement further comprises a first dental ring 30 which is firmly connected to the support profile 21 by means of mounting pins 31,32. The first tooth ring 30 is intended for engagement with a second tooth ring 33 which is rotatably mounted relative to the bracket 13. The second tooth ring 33 is thus mounted for rotation about a axis of rotation 34.
The second dental ring is provided with an extension 35, which at its distal end 36 is provided with a rotational connection 37, which is connected to a bushing 38 on a guide arm 39.
The guide member 39 is provided at its other end with a fixing bracket 40 mounted on the curve support 17. As the actuator 22 thus rotates the second dental ring 33, a displacement of the curve support along the support profile will be established via the conductor 39 and at the same time the first tooth ring 30 causes a rotation of the support profile 31 with the basket 3 mounted thereon. This rotation takes place about a axis of rotation of the first tooth ring 30,
FIG. 2 shows a perspective view of the curve 3 mounted on the outer boom 8. The outer boom is made as a parallelogram with a main profile 41 connected to guide rods 42. The guide rods 42 are arranged on each side of the main profile 41 so that a parallelogram for the displacement of the curve is established with a substantially horizontal orientation of the bottom of the curve 16. The support profile 21 is seen under the curve 3.
FIG. 3 is a plan view similar to FIG. 2. In this position, the basket will be positioned at a starting position where the wall 43 of the basket farthest from the outer boom 8 is perpendicular to the plane 44 where the two booms 7 and 8 make a pivot.
FIG. 4 shows the curve 3 with an initial counterclockwise oscillation. Here we see how the two dental crowns 30,33 interact.
FIG. 5 shows a position where the curve 3 is displaced maximally along the support profile 21. It is seen here that the inner wall 45 of the curve which is closest to the outer boom. 8, is free from the outer boom 8. In this position, it will be possible for an operator to do work against an adjacent wall from the wall 43 of the basket, which in a starting position will be farthest from the outer boom 8.
Since the curve 3 is often rectangular with different side lengths, it is often preferred that an operator work from the side wall 43, thereby establishing a longer operating radius than when working from one of the perpendicular side walls 46 having a shorter length than the side walls 43 of the curve. 45th
FIG. 6 shows the clock 3 with an initial clockwise oscillation from the one shown in FIG. 3.
FIG. 7 shows a car leading by curve 3 rotated 90 ° clockwise relative to its starting position.
FIG. 8 shows a position similar to FIG. 3 with the basket removed so as to more clearly see the mutual position of the support arrangement elements.
FIG. 9 corresponds to FIG. 4, but also with the curve removed. FIG. 10 corresponds to FIG. 5, but also with the curve removed. FIG. 11 corresponds to FIG. 6, but also with the curve removed. FIG. 12 corresponds to FIG. 7, but also with the curve removed.
FIG. 13 is an enlarged view similar to FIG. 3 and 8. Herein, the support profile 21 is transparent so that the movement of the actuator 22. is more clearly seen. 14 is also an enlarged view corresponding to FIG. 4 and 9. Again, the support profile 21 is transparent.
FIG. 15 corresponds to FIG. 5 and 10. Again, the support profile 21 is transparent. Thus, it is seen how the actuator 22 cooperates with the pivot arm arrangement 25.
FIG. 16 is a perspective view in which the support profile 21 is also transparent; 16 shows a position of the curve support 17 which corresponds to that of FIG. 3 and 8.
FIG. 17 is a perspective view in which the support profile 21 is transparent. The position shown in FIG. 17 corresponds to the position shown in FIG. 5 and 10.
