    [001] The invention is related to a clamp system for a thin object, such as a stack or pipe and the like, said system comprising a structure defining a longitudinal axis, in which the object and the structure serve to be arranged around one another in such a way that the longitudinal axis of the frame is generally parallel to the longitudinal axis of the object, as well as fastening means for securing the object with respect to the frame.
    [002] Such a clamp system is known. The clamp system can be arranged around the object, or it can be inserted into it if the object is hollow. Generally, the object can be fixed by means of such a clamp system so as to be held immobile in opposite directions along the longitudinal axis.
    [003] Document US2009120649 A1 discloses a slide assembly for securing a pipe during well drilling operations. The assembly has a casing with a hole to receive a section of pipe. The pockets in the casing are spaced circumferentially around the hole. Each of the pockets have side walls facing each other and are connected to each other through a back wall that has a sloping surface. A slider segment is located in each pocket, each slider segment having side edges that engage the side walls of one of the pockets. Each sliding segment has a back side with a slanted surface that fits the slanted surface to the back wall of the pocket. Each of the sliding segments is movable inside your pocket from an upper outer position to a lower inner position in the attachment socket with the barrel. The slide assembly holds the pipes in a vertical position. The angled sections hold the barrel securely. Once the assembly firmly holds the barrel, axial movement of the barrel is no longer possible.
    [004] However, in specific cases it is desirable to keep the object fixed in one direction only along the longitudinal axis. In the opposite direction, the object must then be able to be moved with respect to the clamp system, without inactivating the clamp system. Therefore, the aim of the invention is to provide a clamp system that is active in only one direction along the longitudinal axis.
    [005] This objective is achieved in that the fastening means comprise: - at least one gripping device that is rotationally connected to the structure according to an axis of rotation that is oriented transversely with respect to the longitudinal axis of the structure, said device of gripping having a gripping state for fixing said object with respect to the structure and an inactive state, and - at least one limiter defining an end position of the gripping device, said gripping device in the gripping state and positioned in said final position preventing the object from moving with respect to the frame in a first axial direction along the longitudinal axis of the frame, in which the first axial direction of the gripping device is kept pressed against the restraint, and said gripping device permitting that the object moves with respect to the structure in a second axial direction opposite the first axial direction.
    [006] Thus, the slender object is held fixedly in the first axial direction, but nevertheless can be moved in the opposite direction as a result of the circumference that the gripping device is not stabilized in that direction. As soon as the object is moved in this direction, the gripping device will tilt around its axis of rotation. Also, the gripping force exerted by the gripping device on the object will then be reduced as a result of this tilting effect, whereby the desired movement of the object is further promoted.
    [007] Preferably, a gripping device is mounted on the frame by means of a respective pin. Thus, the gripping device is displaceable between an active position which is radially and/or transversely oriented with respect to the longitudinal axis of the frame and an inactive position inclined with respect to the active position oriented transversely and/or transversely respectively radially. The limiter can be provided on the structure and/or a base or installation. The base or assembly can be made as separate components, however, it can also be made as an integral part of the structure. In order to ensure proper gripping action, a gripping device is preferably biased towards the limiter, such as by an elastic pretension. Movement of the gripping device away from the limiter occurs in the opposite direction to the direction of the deflection force.
    [008] The clamp system can be realized in several ways. According to a first embodiment, the system can be designed for insertion into a hollow object, in which gripping device is realized to fix the inner surface of the hollow object. According to another embodiment, the clamp system can be designed to enclose the object, wherein the structure delimits a passage to accommodate the object and the gripping device is intended to secure the external surface of the object.
    [009] In this embodiment, the structure may comprise the halves of the structure that are connected to each other through a hinge, the hinge axis of which is generally parallel to the longitudinal axis of the structure, said halves of the structure being transferable between an active position closed one on top of the other around the object, and an open position in which the frame can be positioned over the object. Furthermore, closure means may be provided on the frame halves to keep said frame halves pressed together respectively to leave said frame halves free.
    [010] According to another embodiment, the clamp system may comprise a wedge-type clamp having wedge assemblies associated with the structure to provide frictional engagement with said object as a result of a relative displacement of the wedge-type clamp with respect to the object according to the longitudinal axis.
    [011] Such a clamp system is generally known. Once the wedge-type clamp has been arranged around the object, the wedge sets can be activated in order to obtain an initial clamping action on the object. Subsequently, the clamping action can be increased due to the structure and the object moving with respect to each other, for example under the influence of gravity or a pulling force until the relative movement stops and an equilibrium is achieved between these forces. and the frictional forces generated by the clamping action. The advantage of such a wedge-type clamp is its inherent redundancy, which ensures that the object can be lifted without running the risk of slipping off the wedge-type clamp.
    [012] Typically, the initial clamping action is initiated by energizing the specific wedge assembly drives, such as the hydraulic piston/cylindrical devices. Thus, objects that are oriented horizontally in a reclined position can also be gripped. In the process of subsequently lifting the object, the gripping action increases under the influence of gravity forces acting on the object, and which causes the wedge assemblies to be more fixed on the object.
    [013] It will be clear that the initial step of such a lifting operation performed on a reclining object is critical. The clamping action exerted by the wedge assemblies is completely dependent on the actuating force of the piston/cylindrical devices acting on the wedge assemblies. However, it appears that in specific cases, this initial clamping action is not sufficient to secure the position of the wedge clamp with respect to the object. Depending on the lifting forces exerted on the wedge clamp, slippage may occur between the clamp and the object, which would make the lifting operation impossible.
    [014] Therefore, further improvement can be obtained in a clamp system as described above, which is more suitable for lifting recumbent objects. This improvement includes a gripping device being arranged with respect to the wedge assemblies in such a way that during said relative displacement of the object and the wedge-type clamp said gripping device is transferred from the gripping state, in which the object is held with relation to the structure by the gripping devices, to the inactive state in order to establish said friction fit between the wedge sets and the object.
    [015] In the clamp system according to the invention, the wedge-type clamp is arranged around the object normally. Next, the wedge assemblies are activated and subsequently the gripping devices which are mounted on the frame in addition to the wedge assemblies are activated so that the object is fixedly held with respect to the frame. Under these conditions, the object can be safely lifted without the risk of slipping off the wedge clamp. Subsequently, the object can be transferred to a more vertical position, which would allow the provision of friction fit by the wedge assemblies, if they were allowed to move relative to the object. In order to make such relative movement possible, it is necessary that the gripping devices gradually give way. The proper arrangement of the gripping devices with respect to edge-type assemblies allows for such a gradual transition from a holding force exerted by the gripping devices, to a containing force exerted by the wedge assemblies.
    [016] The gripping devices are mounted on the structure by means of a respective pin that allows rotation according to a respective pin axis that is oriented tangentially or transversely with respect to the structure, and whose gripping devices are displaceable between a position an active position that is radially or transversely oriented with respect to the longitudinal axis of the frame and an inactive position slanted with respect to the active position that is transversely or radially oriented.
    [017] In this system, a gradual release of the gripping action of the gripping devices on the object is obtained by allowing the gripping devices to move with the object while this object is displaced relative to the wedge-type clamp under the influence of the gravity during the process of lifting the object. Simultaneously, this relative displacement also causes the wedge assemblies to come into action, so that at the same time the gripping devices give way, they begin to increase their gripping action on the object. Thus, a safe and reliable transfer of gripping the object with the gripping devices is guaranteed.
    [018] Preferably, the gripping devices are positioned at a distance in the axial direction of the wedge assemblies. Also, the gripping devices can be oriented radially with respect to the frame, and/or transversely with respect to the longitudinal axis of the frame. Thus, the gripping devices can be pivotable radially or transversely according to the direction in which the wedge assemblies are activated. The frame has opposite ends in the axial direction, so that the gripping devices are positioned at the end facing in the fastening direction of the wedge assemblies.
    [019] Furthermore, the invention is related to a gripping device by a clamp body system as described above, comprising a piston/cylindrical device that is transferable between an active position in which the piston extends with respect to the cylinder , and an inactive position in which the piston is retracted with respect to the cylinder, as well as a base for mounting on the frame and in which the base of the piston/cylindrical device is connected via a pin axis of the pin which is transversely oriented with respect to the longitudinal direction of the piston/cylindrical device.
    [020] Also, the invention is related to a method for lifting a thin object by means of the clamp system as described above, comprising the steps of: - fitting the clamp around a reclining object, - activating the gripping devices of so as to grip the external surface of the recumbent object, - lifting the object gripped by the gripping devices and transferring said object to a more vertical position, - during the process of transferring the object to the vertical position, the displacement of the object with respect to the structure in order to activate or further activate the wedge assemblies, - and during the process of transferring the object to the vertical position, transfer the gripping devices from the gripping state to the inactive state. Alternatively, the method may comprise the steps of: - introducing the structure into the recumbent object, - activating one or more gripping devices in order to grip the inner surface of the recumbent object, - lifting the object gripped by the gripping device and transferring the said object towards a vertical position, - during the process of transferring the object to the vertical position, move the object with respect to the structure in order to further activate or activate its wedge sets, - and during the process of transferring the object to the vertical position, transfer the gripping device(s) from the gripping state to the idle state.
    [021] In particular, this method may comprise the steps of: - during the process of transferring the object to the vertical position, transferring the gripping devices from the gripping state to the inactive state by making the gripping device rotate around the respective axis of rotation of this.
    [022] Also, this method can comprise the steps of: - displacement of the object with respect to the clamp under the influence of gravity as a result of transferring the object to the vertical position, - during the step of displacement of the object with respect to the clamp , rotate the grip device from the grip position to the idle position.
    [023] The invention will now be further described with reference to the realization of the clamp system as shown in the drawings.
    [024] Figure 1 shows a bottom perspective view of a first embodiment of the clamp system.
    [025] Figure 2 shows a perspective view of a gripping device for the clamp system of figure 1.
    [026] Figures 3-5 show several steps in the process of lifting and verticalizing an object.
    [027] Figure 6 shows part of the clamp system of figure 1 as applied to a reclined object according to figure 3.
    [028] Figure 7 shows part of the clamp system of figure 1 as applied to a erected object according to figure 5.
    [029] Figure 8 shows a partial view in longitudinal section of a second embodiment of the clamp system.
    [030] The first embodiment of the clamp system as shown in figure 1 consists of the wedge-type clamp which has generally been denoted by the reference numeral 1, as well as the 2 series of gripping devices 3. The wedge-type clamp 1 has an annular frame 4 consisting of two frame halves 5, 6 which are connected together via hinge 7 and an actuator half 8 at one end. By energizing the actuator 8, the frame halves 5, 6 can be alternated around the hinge 7 between an open and closed position, as shown. In the open position, the frame halves can be placed around an object which after closing the frame halves 5, 6 are then accommodated within the internal space 9 of the frame 4. The clamp system can be lifted by means of eyebolts 10, on which hoisting ropes of a crane and the like are to be mounted.
    [031] Around the internal space 9 of the structure, several sets of wedge 11 were spaced. These wedge assemblies are shown in radial section in figure 6 and 7, and consist of a known manner of wedge parts 12, 13, which are slidable together according to tilting surfaces 14. The inner wedge part 13 has a friction surface 15 which engages the outer surface 30 of object 16 as shown in figures 3-7. The initial friction fit between the wedge assembly 11 and the object can be achieved by means of the wedge assembly 26 driver. In the vertical position, the wedge assemblies 11 additionally secure the object 16 securely in the inner space 9 of the clamp-type wedge 1 under the influence of gravity, the clamp system itself being suspended from a hoist and the like by means of lifting cables 23 connected to the lifting eyes 10 (only one of these being shown in figure 3).
    [032] In a reclined position of object 16 as shown in figure 6, this clamping action of the wedge assemblies is limited, as gravity does not influence the position of object 16 and clamp system 1 with respect to each other. In order to still be able to lift the object from this reclined position safely and reliably, the 2 series of gripping devices 3 have been mounted on an axial end of the frame 4. These gripping devices 3 each consist of a piston. cylindrical device 17 and mounting plate 21. Housing 18 thereof is connected to mounting plate 21 via pin 22, the pin axis running transversely to the longitudinal axis of piston/cylindrical device 17. Piston 19 has a gripping surface 20 at its free end. By means of a spring member 24 which is hung around the casing 18 and both ends of which are connected to the mounting plate 21, the piston/cylindrical device 17 is moved against said mounting plate 21 and is held under the pre-tension against the face of the limiter 25 thereof.
    [033] After the clamp system 1 has been arranged around the object 16 by opening and subsequently closing the frame halves 5, 6, the gripping devices 3 are energized so that the gripping surfaces 20 thereof are pressed about the object. Thus, a stable position of the object 16 with respect to the clamp system 1 is obtained. Spring members 24 are holding the piston/cylindrical devices 3 in the clamping position, at right angles to the axis of the frame 4.
    [034] As soon as the object is somehow lifted in this condition, it starts to tilt. Thus, the force of gravity obtains a component that is directed along the longitudinal direction of the object and the axis of the structure. Initially, any movement of the object under the influence of this gravity force component with respect to the structure is impeded by the spring members 24 which hold the piston/cylindrical devices in position opposite the corresponding limiter faces 25. However, as soon as the component the gravity force in question exceeds a certain limit, the spring elements 24 yield and the piston/cylindrical devices begin to rotate around the pins 22. This causes the wedge assemblies 11 to begin exerting a frictional force on the object 16, so that finally all the gravitational force acting on object 16 is produced by said wedge sets. The gripping devices 3 then remain inactive against the object 16, having no further effect in lifting the object.
    [035] Figures 3-5 show a particular lifting operation in which the wedge assembly can be used in a particular beneficial way. As shown, object 11 has a reclined or horizontal position. Near one of its ends the clamp system 27 is positioned, a first hoisting rope 23 extending between the clamp system 27 and a double hoist block 28 suspended from a crane (not shown). In addition, a second lifting cable 29 extends between this double lifting block 28 and the object 11, near the other end of this.
    [036] The force F as exerted by the first lifting cable 23 on the clamp system 27 has an FI component that is oriented in accordance with the axis of the clamp system 27, and against the direction in which the wedge sets thereof would be activated. In such a case, the clamping action exerted by the wedge assemblies on the object, as obtained after energizing its actuators, appears to be insufficient to stabilize the clamp system 27 with respect to the object 11. However, by energizing the gripping devices 3 as described above, such a stable position of the clamp system 27 can still be obtained. As the force component FI causes the piston/cylindrical devices 17 to be pressed firmly onto the corresponding stops 25 faces, the stability of the clamp system 27 with respect to the object is further verified.
    [037] The realization of the clamp system written above is adequate to accommodate an object within the internal space 9 of this. As an alternative, the clamp system can be realized for inserting a hollow object into the hollow space, as shown in figure 8. In this case, both the wedge assemblies 11 and the gripping devices fit into the inner surface 31 of the object. 16. The way to handle this clamp system and object, however, is similar to the clamp system described above. REFERENCE NUMBER LIST 1. Wedge-type clamp 2. Clamping device series 3. Clamping device 4.
