DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Example: like Figure 1-17 As shown, this embodiment proposes a highly stable hoist for a concrete pipe pile mold, which is used to hoist a pipe pile mold 30, and includes a moving beam 13, on which a plurality of groups of movable shells 20 are arranged; The movable housing 20 is provided with a mounting plate 28, and a driving screw 29 is rotatably provided on the mounting plate 28. The movable housing 20 is also provided with a first clamping assembly 40 and a second clamping assembly 50, and the driving screw 29 is connected with the first clamping assembly 40 and the second clamping assembly 50. The pipe pile mold 30 is provided with an upper mold 36 and a lower mold 32. The driving screw 29 rotates so that the first clamping assembly 40 is clamped on the upper mold 36, and the second clamping assembly 50 is clamped on the lower mold 32 at the same time.

[0019] In this embodiment, when the pipe pile mold 30 is hoisted, the mobile housing 20 is first displaced so that the multiple groups of mobile housings 20 are adjusted to the position above the pipe pile mold 30, and then the mobile beam 13 is lowered so that the multiple groups of mobile housings 20 are displaced toward the pipe pile mold 30. During the displacement process, the first clamping assembly 40 and the second clamping assembly 50 are opened. When the mobile housing 20 is suspended above the pipe pile mold 30, the first clamping assembly 40 and the second clamping assembly 50 are closed. The pipe pile mold 30 is clamped by the first clamping assembly 40 and the second clamping assembly 50 at the same time, and then the mobile beam 13 is displaced, thereby driving the pipe pile mold 30 to be displaced, and the position of the pipe pile mold 30 can be adjusted. Of course, in the process of lifting the pipe pile mold 30, the two outermost groups of mobile shells 20 are displaced toward the center direction of the mobile beam 13, and the pipe pile mold 30 is positioned by pulling the two groups of mobile shells 20, which can avoid the shaking of the pipe pile mold 30 during the lifting process; The first clamping assembly 40 and the second clamping assembly 50 are used to clamp the pipe pile mold 30 at the same time, so that the lifting device can firmly clamp the pipe pile mold 30 during the lifting and transportation process, achieving a double insurance effect, avoiding the shaking and sliding of the pipe pile mold 30, and improving the safety and stability of the operation; The pipe pile mold 30 is clamped by the first clamping assembly 40 and the second clamping assembly 50. The first clamping assembly 40 and the second clamping assembly 50 can clamp the pipe pile mold 30 at different positions respectively. During the hoisting process, the pipe pile mold 30 can be clamped in multiple directions, so that the weight of the mold can be evenly distributed, the deviation and tilt during the hoisting process can be reduced, and the stability of the hoisting device can be further improved. By adjusting the displacement of the mobile shell 20 on the mobile beam 13, it can be ensured that multiple groups of mobile shells 20 can be accurately positioned above the pipe pile mold 30. In this way, during operation, the hoisting and moving position of the mold can be accurately controlled. At the same time, corresponding adjustments can be made under different operating environments and requirements. It has strong adaptability and can meet the hoisting requirements of concrete pipe pile molds 30 of different sizes and specifications.

[0020] The pipe pile mould 30 is clamped simultaneously by the first clamping assembly 40 and the second clamping assembly 50 provided as above. The integrated design unifies the operations of the first clamping assembly 40 and the second clamping assembly 50 into a driving screw 29 system, thereby reducing the number of required driving components and simplifying the overall structure. This not only helps to reduce the complexity of design and manufacturing, but also reduces the difficulty and cost of maintenance.

The outer wall thread sleeve of the first threaded outer wall 291 is provided with a first connecting sleeve 292, and the outer wall thread sleeve of the second threaded outer wall 293 is provided with a second connecting sleeve 294. The pitch of the first threaded outer wall 291 is smaller than the pitch of the second threaded outer wall 293. The first connecting sleeve 292 is connected to the first clamping assembly 40 , and the second connecting sleeve 294 is connected to the second clamping assembly 50 .

[0022] In this embodiment, when the pipe pile mold 30 is clamped, the driving screw 29 is rotated, and the first threaded outer wall 291 and the first connecting sleeve 292 are threadedly matched, and the second threaded outer wall 293 and the second connecting sleeve 294 are threadedly matched, so that the first connecting sleeve 292 and the second connecting sleeve 294 are lifted or lowered at the same time, so that the first clamping assembly 40 and the second clamping assembly 50 are closed or opened at the same time; Of course, since the pitch of the first threaded outer wall 291 is smaller than the pitch of the second threaded outer wall 293, the first clamping assembly 40 and the second clamping assembly 50 can clamp the pipe pile mold 30 at the same time under the same operation steps, which reduces the complexity of operation, improves work efficiency, significantly optimizes the operating performance of the sling, improves its adaptability, flexibility and accuracy, and also helps to reduce manufacturing and maintenance costs; Of course, the thread pitch of the first thread outer wall 291 and the second thread outer wall 293 is set according to the actual usage. By simply adjusting the rotation of the driving screw 29, the ideal clamping position and strength can be achieved, thereby improving the adaptability and efficiency of the sling; Of course, the clamping force of the first clamping assembly 40 and the second clamping assembly 50 can also be accurately adjusted to ensure that appropriate clamping force can be provided for pipe pile molds 30 of different sizes and weights. This design provides greater flexibility and adaptability and is suitable for a wide range of application scenarios.

[0024] In this case, when the first connecting sleeve 292 is lifted, since the two sets of first connecting rods 43 are connected to the first connecting sleeve 292, the two sets of first clamping claws 41 simultaneously move toward the axial direction of the driving screw 29 to clamp the upper mold 36.

[0025] In this embodiment, when the first clamping assembly 40 clamps the pipe pile mold 30, the driving screw 29 is rotated to lift the first connecting sleeve 292, and the first connecting rod 43 drives the first clamping claw 41 to rotate about the axis of the first mounting rod 26. When the two groups of symmetrically arranged first clamping claws 41 are in contact with the pipe pile mold 30 at the same time, the clamping process is completed. Of course, when the clamping needs to be released, the driving screw 29 is rotated in the opposite direction to lower the first connecting sleeve 292.

[0026] Specifically, two sets of second mounting rods 27 are symmetrically arranged on the mobile housing 20; The second clamping assembly 50 includes two groups of second clamping claws 52, and a second connecting plate 51 is disposed on the second clamping claws 52. The second connecting plate 51 is rotatably disposed on the second mounting rod 27, and a second connecting rod 53 is movably disposed between the second clamping claws 52 and the second connecting sleeve 294; The second connecting sleeve 294 is lifted, and the second clamping claw 52 is rotated about the axis of the second mounting rod 27 through the first connecting rod 43 , and is displaced toward the axis of the driving screw 29 to clamp the lower mold 32 .

[0027] In this case, when the second connecting sleeve 294 is lifted, since the two sets of second connecting rods 53 are connected to the second connecting sleeve 294, the two sets of second clamping claws 52 are simultaneously displaced toward the axial direction of the driving screw 29 to clamp the lower mold 32.

[0028] In this embodiment, when the second clamping assembly 50 clamps the pipe pile mold 30, the driving screw 29 is rotated to lift the second connecting sleeve 294, and the second clamping claw 52 is driven by the second connecting rod 53 to rotate along the axis of the second mounting rod 27. When the two groups of symmetrically arranged second clamping claws 52 are in contact with the pipe pile mold 30 at the same time, the clamping process is completed. Of course, when the clamping needs to be released, the driving screw 29 is rotated in the opposite direction to lower the second connecting sleeve 294.

[0029] Specifically, the upper mold 36 is provided with a plurality of groups of upper mold running wheel semi-rings 37, the lower mold 32 is provided with a plurality of groups of lower mold running wheel semi-rings 31, the plurality of groups of upper mold running wheel semi-rings 37 are adapted to the plurality of groups of lower mold running wheel semi-rings 31, the upper mold 36 is symmetrically provided with two groups of upper mold tongue and groove plates 34, the lower mold 32 is symmetrically provided with two groups of lower mold tongue and groove plates 33, the two groups of upper mold tongue and groove plates 34 are adapted to the two groups of lower mold tongue and groove plates 33; The central axes of the two groups of the first clamping claws 41 are arranged perpendicular to the central axes of the two groups of the second clamping claws 52; The two end faces of the upper mold running wheel half ring 37 and the lower mold running wheel half ring 31 are both provided with clamping grooves 35, and the two groups of the first clamping claws 41 are respectively extended into the two groups of clamping grooves 35 to clamp the upper mold 36, and the two groups of the second clamping claws 52 are respectively extended to the bottom of the two groups of lower mold tongue and groove plates 33 to clamp the lower mold 32.

[0030] In this embodiment, when the pipe pile mold 30 is hoisted, the first clamping claw 41 extends into the clamping groove 35 to clamp the upper mold 36, and the second clamping claw 52 extends below the lower mold tongue and groove plate 33 to clamp the lower mold 32; Of course, the upper mold 36 can be clamped by the first clamping claw 41 alone. In this step, the upper mold 36 can be raised by a gasket to facilitate the second clamping claw 52 to extend below the upper mold 36. Of course, the lower mold 32 can also be clamped by the second clamping claw 52 alone. In this step, the first clamping claw 41 is in a wheel-bypass state, that is, the first clamping claw 41 moves toward the axial direction of the driving screw 29, but does not participate in the clamping process.

[0031] Specifically, a support plate 297 is provided at the bottom end of the driving screw 29, the driving screw 29 is rotatably disposed on the support plate 297, and a support rod 298 is provided between the support plate 297 and the moving housing 20; The support plate 297 is provided with an extrusion threaded hole 295, and a threaded extrusion screw 65 is arranged in the extrusion threaded hole 295.

The support plate 297 is provided with multiple groups of guide holes 296, and the multiple groups of guide rods 64 are adapted to the multiple groups of guide holes 296.

[0032] Specifically, the inner cavity of the extrusion screw 65 is hollow, and a movable rod 62 is provided on the movable plate 63.

[0033] In this embodiment, during the rotation of the driving screw 29, the extrusion screw 65 extends into the extrusion threaded hole 295, and the extrusion screw 65 is displaced at the same time. When the first clamping assembly 40 and the second clamping assembly 50 clamp the pipe pile mold 30, the extrusion screw 65 is displaced toward the pipe pile mold 30, so that the extrusion plate 60 contacts the pipe pile mold 30, and the pipe pile mold 30 is pressed to improve the stability during the clamping process. Of course, by setting the movable rod 62 to slide in the inner cavity of the extrusion screw 65, and under the support of the extrusion spring 61, the extrusion plate 60 and the pipe pile mold 30 can be changed from the original hard contact to elastic contact, thereby avoiding damage to the pipe pile mold 30 caused by hard contact. At the same time, it also has a certain buffering effect, which can alleviate the impact force during the clamping and moving process, further protect the pipe pile mold 30, and can adapt to the lifting requirements of pipe pile molds 30 of different sizes and specifications, meet the use requirements in different operation scenarios, and improve the flexibility and adaptability of the hanger.

[0036] When making adjustments, you only need to pull the extension plate 5231 out of the extension receiving groove 5212, and then fix it with the positioning bolt 522.
