[0024] It should be noted that by setting a limiting mechanism, the effect of limiting and fixing the pipe piles is achieved, and at the same time, it is convenient to limit and fix pipe piles of different sizes, thereby facilitating the movement of the pipe piles. The worm 4 and worm wheel 6 are self-locking, which increases stability and safety during the movement.

Fixed grooves are provided on the left and right sides of the inner wall of the base 1, and the fixed blocks 14 are slidably connected to the fixed grooves. A plurality of pulleys 15 are fixedly installed at the bottom of the fixed plate 13, and four dampers 16 are fixedly installed on the top of the fixed plate 13. The outer sides of the four dampers 16 are each provided with a first buffer spring 17, and a limiting assembly is provided inside the base 1.

[0026] It should be noted that, by providing the buffer assembly, the effect of buffering and reducing shock on the sliding platform is achieved, thereby ensuring the stability and safety of the sliding platform during movement, and further increasing the service life of the pulley 15.

[0027] See also Figures 1 to 4 In this embodiment, the limiting assembly includes a sleeve 18 fixedly connected to the top of the fixed plate 13, a second buffer spring 19 is fixedly connected to the inside of the sleeve 18, the top of the second buffer spring 19 is fixedly connected to the support plate 20, and the top of the support plate 20 is fixedly connected to the support rod 21.

[0029] The working principle of the above embodiment is: the sliding platform for hoisting pipe piles,

[0030] 1) When in use, by setting a limiting mechanism, the pipe pile is placed on the second limiting plate 11, and the handle 22 is turned. The handle 22 drives the worm 4 to rotate, the worm 4 drives the worm wheel 6 to rotate, the worm wheel 6 drives the threaded rod 5 to rotate, and the threaded rod 5 drives the connecting rod 7, the connecting plate 8 and the first limiting plate 10 to move downward. By setting a support block 9 and a support groove, it is limited and supported to increase its stability during movement, so that the pipe pile is limited and fixed by the first limiting plate 10. The worm 4 and the worm wheel 6 are self-locking, which increases the stability during limit fixation.

[0031] 2) By setting up multiple pulleys 15, it can run on the ship's track. The pulley 15 squeezes the fixed plate 13. By setting up the fixed block 14 and the fixed groove, the fixed plate 13 is limited and supported, thereby increasing the stability during movement. By setting up the damper 16 and the first buffer spring 17, the fixed plate 13 is buffered and shock-absorbing, thereby increasing the stability of the pulley 15 during movement.

[0032] 3) By setting a limit assembly, the second buffer spring 19 further buffers and reduces shock, further increasing its stability during movement, preventing it from being compressed and deformed by the pipe pile, and extending its service life. When the pipe pile is hoisted, the first limit plate 10 moves upward. When one end of the pipe pile is hoisted, the other end contacts the baffle 12 and then lifts upward to complete the hoisting, which is convenient for users and improves the practicality of the sliding platform.
