Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel construction auxiliary equipment and relates to a transverse support beam disassembly device. Background Art

[0002] In an open-cut tunnel, after the retaining piles are driven and the foundation pit is dug, retaining walls will be constructed on both sides of the foundation pit. After construction, for water-rich areas, the water pressure is high, and there is still a certain risk shortly after construction. Therefore, it is necessary to construct the top concrete transverse support beam and the transverse steel support beam near the middle to reinforce the retaining wall. When constructing the transverse steel support beam, one end is butted against the end and a wedge is used to apply a pre-tightening force, thereby greatly improving the reinforcement effect. When dismantling, large suspension equipment is usually arranged on both sides of the foundation pit, and hydraulic cylinders are used to loosen the wedges before dismantling. Large equipment occupies a large space and is difficult to arrange in a narrow area, which makes dismantling difficult. Summary of the invention

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] Example 1: Figure 1-3As shown, a transverse support beam disassembly device includes a hydraulic cylinder 1, a sliding plate 2, a hand-operated hoist 3 and a steel wire rope 4. Two hydraulic cylinders 1 are used, which are symmetrically installed on the abutting end heads 6 connected to the ends of the transverse support beams 5, and the two ends of each hydraulic cylinder 1 abut against the end faces of the transverse support beams 5 and the inner end faces of the abutting end heads 6, respectively. Two steel wire ropes 4 are used, which are bolted to the transverse support beams 5 near the two ends, respectively. Each steel wire rope 4 is connected to the sliding plate 2 through a hand-operated hoist 3, and the sliding plate 2 is overlapped on the two top concrete support beams 7. After the two hydraulic cylinders 1 are extended, the transverse support beams 5 and the abutting end heads 6 can be tightened. The wedge 8 is taken out. When in use, the steel wire ropes at both ends of the transverse support beam (the steel wire rope 4 is usually hung on the cement wall on the side of the foundation pit to play a certain protective role and prevent it from falling) are hung on the anti-drop hooks under the chain, and the hand hoist is operated to pre-tighten the chain, and the two hydraulic cylinders are sent between the abutment end and the end face of the transverse support beam. The two hydraulic cylinders are operated at the same time. When the wedge 8 is loosened, the wedge is taken out. At this time, the weight of the support beam is suspended and supported on the sliding plate by two hand hoists. The hand hoist is operated to lower the transverse support beam to complete the construction. This structure can also realize the installation of the transverse support beam.

[0016] In order to ensure the stability of the hydraulic cylinder, a platform 9 for placing the hydraulic cylinder 1 is provided on the abutting end head 6 .

[0017] In order to facilitate the removal of the wedge after it is loosened, a hanging hole 10 is set on the top of the wedge 8, and the hanging hole is connected to the sliding plate 2 through a hanging rope 11. After loosening, the hanging rope can be pulled to remove the wedge, and then the hydraulic cylinder is loosened to suspend the transverse support beam.

[0018] The lever hoist 3 is convenient for operation, and the lever hoist is installed above the sliding plate, that is, the anti-drop hook 15 of the lever hoist 3 is hung on the cantilever beam 12, and the cantilever beam 12 is fixedly connected to the support frame 13 horizontally and vertically. The lower end of the support frame 13 is detachably fixedly connected to the upper surface of the sliding plate 2. A through hole 14 is provided on the sliding plate 2 to pass through the chain 22 of the lever hoist 3. The through hole 14 can be arranged directly opposite to the lever hoist 3. A plurality of through holes 14 are arranged at intervals along the length direction of the sliding plate 2. By operating the handle 21 on the lever hoist, the lever hoist can be pulled up and down to move the chain. The support frame is used for support, which can increase the operating height of the handle, and the operation can be completed while standing, reducing labor intensity, saving time and effort. A plurality of through holes are provided. Because the transverse support beams are arranged at intervals, it is necessary to disassemble the next transverse support beam (multiple steel support beams arranged below the same two adjacent concrete support beams), and move the support frame to the next position for fixing, so as to realize the suspension directly facing the transverse support beam. Operating a lever hoist on the sliding plate is a high-risk operation. Therefore, in order to improve the safety of operation, guardrails are arranged on both sides of the sliding plate 2.

[0019] A large number of steel bars are embedded under the abutment end head for installing the hydraulic cylinder. Due to the obstruction of the steel bars, it is difficult to place the hydraulic cylinder. Therefore, a clamp is used to send it to the abutment end head, that is, a transverse support beam disassembly device also includes an operating rod 16 for placing the hydraulic cylinder 1, and an arc-shaped groove 17 is arranged at the top of the operating rod 16. An elastic binding belt 18 is arranged on the arc-shaped groove 17. One end of the binding belt 18 is fixedly connected to one side of the arc-shaped groove 17, and the other end is hung on a locking hook 19. The locking hook 19 is arranged on the operating rod 16, and a pull rope 20 is connected to the other end of the binding belt 18. The pull rope 20 can pull the binding belt 18 out of or hang it on the locking hook 19, place the hydraulic cylinder in the arc-shaped groove and use the binding belt to bind it, and send it to the platform on the abutment end head through the operating rod, pull the pull rope, and the binding belt is removed from the hook, and then the arc-shaped groove of the operating rod is removed, so as to realize the rapid placement of the hydraulic cylinder, avoid the obstruction and placement problem caused by the embedded steel bars under the abutment end head, and save time and effort in placement.

[0020] The above description is only a specific implementation method of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present utility model, which should be included in the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope of the claims.
