[0032] The present application embodiment discloses a hoisting structure for preparing a concrete pipe. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , including a gantry 1, a lateral moving frame 2 is slidably connected to the opposite side of the two gantry frames 1, a lifting mechanism is provided at the bottom end of the lateral moving frame 2, a base 9 is provided at the bottom end of the lateral moving frame 2, and foot pads 13 are fixedly connected at the four corners of the bottom end of the base 9;

[0033] The base 9 is symmetrically provided with clamping assemblies on both sides thereof, and the clamping assemblies include a bidirectional threaded rod 14, a moving block 15, a fixed rod 11, a clamping plate 16 and a linkage mechanism, and the linkage mechanism includes a sprocket 18 and a chain 19. The base 9 is symmetrically fixedly connected with a shell 10 on both sides thereof, and both ends of the bidirectional threaded rod 14 are rotatably connected to the inner walls of both sides of the shell 10 respectively. A driving motor is provided on one side of the shell 10, and its output end is connected to one end of one of the bidirectional threaded rods 14, so that one of the bidirectional threaded rods 14 can be driven to rotate after starting the driving motor.

[0034] See also Figure 4 and Figure 5 The two sprockets 18 are symmetrically arranged on one side of the inner part of the two housings 10 . The sprockets 18 are sleeved on one end arm of the bidirectional threaded rod 14 , and the two ends of the chain 19 are respectively sleeved on the outside of the two sprockets 18 .

[0035] The two sprocket wheels 18 are connected to each other through a chain 19 . When one of the sprocket wheels 18 rotates, the chain 19 can drive the other sprocket wheel 18 to rotate synchronously.

[0036] See also Figure 3 A plurality of moving blocks 15 are symmetrically and slidably connected to both sides of the two shells 10 , and the plurality of moving blocks 15 are respectively sleeved on the arm rods at both ends of the two bidirectional threaded rods 14 .

[0037] The moving block 15 has a threaded hole inside that matches the bidirectional threaded rod 14 . Therefore, when the bidirectional threaded rod 14 rotates, the moving blocks 15 on both sides are driven to shrink inwards or spread outwards.

[0038] See also Figure 4 Two slide grooves are symmetrically opened at the top of the shell 10, the bottom of the fixed rod 11 is slidably connected inside the slide groove, the bottom end of the fixed rod 11 is fixedly connected to the top of the moving block 15, and the moving block 15 can drive the fixed rod 11 to slide on the top of the shell 10 during the movement.

[0039] See also Figure 2 The opposite sides of the plurality of fixing rods 11 are fixedly connected to the two sides of the clamping plate 16 respectively, and a buffer pad 17 is fixedly connected to one side of the clamping plate 16 close to the center of the base 9 .

[0040] During the sliding process, the fixing rods 11 on both sides can drive the clamping plates 16 to move synchronously and stably clamp the concrete pipe. At the same time, by providing the buffer pads 17, the clamping plates 16 can be prevented from causing squeezing damage to the two ends of the concrete pipe.

[0041] See also Figure 1 The lifting mechanism includes a lifting lock 3, a hanging plate 4, a connecting lock 5 and a hook 6. The top of the lifting lock 3 is fixedly connected to the side of the bottom end of the transverse moving frame 2 away from the center, and the bottom end of the lifting lock 3 is fixedly connected to the side of the top end of the hanging plate 4 away from the center. Multiple connecting locks 5 are symmetrically fixedly connected at the four corners of the bottom end of the hanging plate 4. The bottom end of the connecting lock 5 is fixedly connected to the top of the hook 6. By setting the lifting lock 3, the transverse moving frame 2 can drive the hanging plate 4 to move synchronously.

[0042] See also Figure 1 A tightening belt 12 is symmetrically fixedly installed on the top of the base 9, and a plurality of connecting seats 8 are symmetrically fixedly connected to both sides of the base 9. The top of the connecting seat 8 is fixedly connected to a lifting ring 7, and the lifting ring 7 is sleeved on the bottom of the hook 6.

[0043] The implementation principle of this embodiment is: when clamping, after starting the driving motor, one of the two-way threaded rods 14 is driven to rotate. Since the sprocket 18 is sleeved on one end of the two-way threaded rod 14, and the two sprockets 18 are connected by a chain 19, when one of the two-way threaded rods 14 rotates, the two-way threaded rod 14 on the other side can be driven to rotate through the mutual cooperation between the sprocket 18 and the chain 19.

[0044] The movable block 15 has a threaded hole inside that matches the bidirectional threaded rod 14. Therefore, when the bidirectional threaded rod 14 rotates, the movable blocks 15 on both sides will shrink and move inward along the outer wall of the bidirectional threaded rod 14, and drive the clamping plate 16 to shrink and move inward through the fixing rod 11 at the top, and then clamp and fix the concrete pipe to prevent the concrete pipe from falling.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
