[0002] A ramp is a slope or curve that connects the main road and other roads, helping vehicles to enter and exit the main road smoothly. The ramp beam is the key structural part of this connecting facility, mainly used to support and carry vehicle loads and ensure the stability and safety of the bridge. During the construction process of the ramp beam, a lifting device is usually required to lift the cast ramp beam.

[0003] A Chinese patent document with announcement number CN214935316U discloses a hollow beam slab hoisting protection device, comprising a bidirectional hook, a steel wire rope and two support blocks, wherein the inner surface of the bidirectional hook is fixedly connected to a cross bar, grooves are provided on both sides of the cross bar, the inner surface of the groove is in contact with the outer surface of the steel wire rope, a concave block is provided on the outer surface of the steel wire rope, a threaded hole is provided on one side of the two support blocks, a bidirectional threaded rod is threadedly connected between the inner surfaces of the two threaded holes, a rotating block is threadedly connected to both sides of the outer surface of the bidirectional threaded rod, a support seat is fixedly connected to the top of the two rotating blocks, and the two support blocks are fixedly connected to the top of the two rotating blocks. The top of each of the two blocks is fixedly connected with a lifting ring, and the inner surface of the concave block and the inner surface of the lifting ring are connected through a connecting assembly; first, the two-way hook is hung on the hook on the external crane, and then the steel wire rope is placed in the grooves on both sides of the cross bar, and the steel wire rope is located on both sides of the hollow beam plate, and then the support seat is in contact with the bottom of the hollow beam plate, and the pin shaft is inserted into the through hole at this time, so as to connect the concave block and the lifting ring, and the elastic ball on the steel wire rope, and then by rotating the two-way threaded rod, and then using the threaded relationship between the two-way threaded rod and the rotating block, the two rotating blocks move to the relatively close side, so that the side of the support seat is in contact with the side of the hollow beam plate.

[0004] In the above technology, the side of the hollow beam is abutted by the support seat, and the rubber ball is in contact with the upper part of the hollow beam before lifting. During the lifting of the hollow beam, when the wire rope is lifted and tightened, the wire rope will drive the rubber ball to move. At this time, there will still be friction between the rubber ball and the hollow beam, which will cause serious damage to the rubber ball and wear of the hollow beam. Summary of the invention

When the lower surface of the lifting plate 921 abuts against the upper surface of the hollow beam plate, close the driver 922 to complete the vertical position fixation of the top pad 7.

[0039] Reference Figure 3-Figure 5When the hollow beam needs to be clamped, first start the driver 1 922 to drive the lifting plate 921 to descend. During the descent of the lifting plate 921, the mounting plate 913, the top pad 7 and the lifting rod 912 are driven to descend. When the lower surface of the lifting plate 921 abuts against the upper surface of the hollow beam, the lifting plate 921 no longer descends.

A groove for installing the rotating disk 42 is opened on the mounting frame 41, and the rotating disk 42 is set as a T-shaped structure. The top of the rope 2 is wound on the rotating disk 42. One end of the torsion spring is fixedly connected to the rotating disk 42, and the other end is fixedly connected to the mounting frame 41. In the initial state, the torsion spring drives the rotating disk 42, the locking assembly 43 and the rope 2 to move in a direction away from the hollow beam plate.

[0042] Reference Figure 3-Figure 7A receiving block 5 is fixedly provided on one connecting plate 3, and the receiving block 5 is arranged in a "concave" shape structure. A receiving groove 51 is opened on the receiving block 5, and a clamping mechanism 6 for clamping, locking and unlocking with the receiving groove 51 is arranged on the other connecting plate 3. The clamping mechanism 6 includes a clamping block 61 for clamping, locking and unlocking with the receiving groove 51, and an elastic member 62 for driving the clamping block 61 to move into the receiving groove 51. The clamping block 61 is adapted to the receiving groove 51, and a guiding inclined surface is arranged at one end of the clamping block 61. The clamping block 61 is slidably matched with the connecting plate 3 along the length direction of the hollow beam plate. The elastic member 62 directly adopts a spring, and one end of the elastic member 62 is fixedly connected to the connecting plate 3, and the other end is fixedly connected to the clamping block 61. When the two connecting plates 3 are connected, the two connecting plates 3 are first pushed in the direction of approaching each other, driving the receiving block 5 and the clamping block 61 to move in the direction of approaching each other. When the guiding inclined surface of the clamping block 61 abuts against one end of the receiving block 5 close to the clamping block 61, the receiving block 5 will squeeze the guiding inclined surface, and then squeeze the clamping block 61, so that the clamping block 61 slides in the direction away from the receiving block 5 and stretches the elastic member 62. When the clamping block 61 moves to the receiving groove 51, the elastic member 62 releases the elastic restoring force, driving the clamping block 61 to be inserted into the receiving groove 51, and the clamping block 61 is clamped and locked with the receiving block 5. At this time, the bottom pad 8 abuts against the bottom of the hollow beam plate; the clamping block 61 is pushed to slide in the direction away from the receiving block 5, and the elastic member 62 is compressed. When the two connecting plates 3 are pushed in the direction away from each other, the two connecting plates 3 can be disassembled.

[0043] The implementation principle of the hoisting device for erecting ramp beams and slabs of the present invention is as follows: when the hollow beams and slabs need to be hoisted, firstly two ropes 2 are placed on the outside of the hollow beams and slabs, then the hollow beams and slabs are clamped, and the driver 1 922 is started, and the driver 1 922 drives the lifting plate 921 to descend, and during the process of the lifting plate 921 descending, it can sequentially drive the mounting plate 913, the top pad 7 and the lifting rod 912 to descend, and when the lower surface of the lifting plate 921 abuts against the upper surface of the hollow beams and slabs, the lifting plate 921 no longer descends, and at this time, the vertical positions of the mounting plate 913, the top pad 7 and the lifting rod 912 are fixed; Then, the second driver 93 is started, and the second driver 93 drives the two adjacent sliding frames 911 to slide in a direction close to each other. When the sliding frames 911 slide, they can sequentially drive the lifting rod 912, the mounting plate 913 and the top pad 7 to slide toward the hollow beam plate, and then the two top pads 7 abut against the outer side of the hollow beam plate and fix the hollow beam plate; Then, the two connecting plates 3 are pushed in the direction of approaching each other, driving the receiving block 5 and the clamping block 61 to move in the direction of approaching each other. When the guiding inclined surface of the clamping block 61 abuts against the end of the receiving block 5 close to the clamping block 61, the receiving block 5 will squeeze the guiding inclined surface, and then squeeze the clamping block 61, so that the clamping block 61 slides in the direction away from the receiving block 5 and stretches the elastic member 62. When the clamping block 61 moves to the receiving groove 51, the elastic member 62 releases the elastic restoring force, driving the clamping block 61 to be inserted into the receiving groove 51, and the clamping block 61 is clamped and locked with the receiving block 5. At this time, the bottom pad 8 abuts against the bottom of the hollow beam plate, completing the adjustment of the bottom pad 8 and the top pad 7, and the torsion spring can drive the rotating disk 42, the locking assembly 43 and the rope 2 to move in the direction away from the hollow beam plate, so that the rope 2 is tensioned on the side close to the hollow beam plate; Then the lifting mechanism is started, and the hanger 1 is driven to rise by the lifting mechanism to perform the lifting operation on the hollow beam slab.
