Since the friction coefficient between the cables and the pipe piles is relatively small, it is difficult to maintain the horizontal state of the pipe piles during the lifting process. The pipe piles are difficult to maintain stability during the conveying process, causing the pipe piles to slip easily, thereby causing danger. Utility Model Content

[0028] The two slides 2 are threadedly connected to the two threaded rods 33 through the nut 35. The dual-output shaft motor 31 drives the two threaded rods 33 to rotate so that the hook assemblies 4 under the two slides 2 can move away from or close to each other, thereby clamping and hanging the pipe pile. The fixed hanging plate 61 is provided to facilitate the connection between the device and the crane.
[0029] Furthermore, the driving mechanism 3 further includes two connecting rods 32 and a plurality of bearing seats 34. The two connecting rods 32 are respectively fixedly mounted on the two output shafts of the dual-output shaft motor 31 through a coupling. The plurality of bearing seats 34 are equidistantly mounted on the connecting plate 1. The two connecting rods 32 are aligned with the axis of the plurality of bearing seats 34. The end surfaces of the two connecting rods 32 extending out of the two end bearing seats 34 are respectively fixedly connected to the two threaded rods 33.
[0030] By setting a plurality of bearing seats 34 evenly spaced and installed on the connecting plate 1, two connecting rods 32 are respectively fixedly installed on the two output shafts of the dual-output shaft motor 31, and the two connecting rods 32 are aligned with the axis centers of the plurality of bearing seats 34. The end faces of the two connecting rods 32 extending out of the two end bearing seats 34 are respectively fixedly connected to the two threaded rods 33, thereby avoiding the situation in which the two threaded rods 33 are broken or bent during long-term use due to the long distance between them.
[0031] Further, the two hook assemblies 4 each include a C-shaped hook 41 and a fixing plate 42, the two fixing plates 42 are symmetrically mounted on the bottom of the two slide plates 2 away from each other, and the two fixing plates 42 are evenly spaced on one end along the height direction thereof to open a penetrating 421, and the end surfaces of the two C-shaped hooks 41 away from each other are fixedly mounted with bolts 411, and the end surfaces of the two bolts 411 through 421 are threadedly mounted with threaded screw discs 43;

[0033] Furthermore, a connecting frame 6 is fixedly installed on the upper part of the dual-output shaft motor 31 on the driving mechanism 3, and a fixed hanging plate 61 is fixedly installed on the top of the connecting frame 6; by setting the connecting frame 6 on the fixed hanging plate 61, the connection between the device and the crane is facilitated, and the fixed hanging plate 61 can provide protection for the dual-output shaft motor 31.
[0034] Furthermore, limit blocks 36 are fixedly installed on the end surfaces of the two threaded rods 33 that are away from each other; the limit blocks 36 are provided to prevent the nut 35 from sliding off the threaded rod 33 .
[0035] Embodiment 2
[0036] like Figure 4As shown, a pressing assembly 5 is provided at the bottom of the connecting plate 1, and the pressing assembly 5 includes a pressing seat 51 and a round block 53. The top end of the pressing seat 51 is fixedly installed at the axis of the bottom end of the connecting plate 1, and the other end of the pressing seat 51 is provided with a round groove 52. The round block 53 is slidably installed on the round groove 52. A spring 54 is placed in the round groove 52. The head and tail ends of the spring 54 are respectively in conflict with the round block 53 and the inner top wall of the round groove 52.

In this way, when the pipe pile is hoisted, the spring 54 pushes the pressure block 55 to hold the pipe pile downward, so that the pipe pile and the two C-shaped hooks 41 are more closely fitted, and the high-altitude hoisting is more stable, avoiding unnecessary shaking of the pipe pile caused by high wind speed during high-altitude operation.
[0038] Furthermore, a limit ring 56 is fixedly installed at the lower end of the circular groove 52, and a limit disk block 57 is fixedly installed on the circular block 53, and the outer circumferential dimension of the limit disk block 57 is larger than the inner circumferential dimension of the limit ring 56; by setting the outer circumferential dimension of the limit disk block 57 to be larger than the inner circumferential dimension of the limit ring 56, the spring 54 is prevented from pushing the circular block 53 out of the circular groove 52.
[0039] It should be noted that the specific installation method, circuit connection method and control method of the dual output shaft motor 31 used in the present invention are all conventional designs, and the present invention will not elaborate on them in detail.
[0040] The working principle of the utility model is as follows: the dual-output shaft motor 31 drives the two threaded rods 33 to rotate so that the C-shaped hooks 41 under the two slides 2 can move away from or close to each other, and then clamp the pipe pile and lift it.
