[0038] In this embodiment, in the process of the steel trestle pipe pile construction, when the pile tip needs to be welded at the bottom of the pipe pile, the operation steps are as follows:
[0039] First, the pipe column is lifted to the vertical state by the lifting device, and the bottom of the pipe column is kept at a certain height from the ground;
[0040] Then the pile tip is placed inside the support ring seat 101 (it should be noted that the pile tip is a conical structure, and the conical head of the pile tip faces downward), and the plurality of limiting blocks 102 can limit the pile tip, so as to ensure that the pile tip does not fall off;
[0041] Then the entire device is sleeved with the pipe column through the connecting sleeve 104, and is moved upward, so that the top of the pile tip is attached to the bottom end of the pipe pile. At this time, any one of the rotating arms 205 is rotated downward, and the rotating arm 205 is pushed upward by the transmission gear 206 when it rotates, so that the toothed arm 204 and the lifting ring block 203 move upward as a whole. The lifting ring block 203 can extrude the plurality of L-shaped clamping blocks 201, so that the plurality of L-shaped clamping blocks 201 move inwardly of the connecting sleeve 104 and extrude the spring 202 to contract;

[0045] In this embodiment, the inclined surface structure of the L-shaped clamping block 201 and the lifting ring block 203 makes the extrusion of the lifting ring block 203 to the L-shaped clamping block 201 more smooth, reduces the moving resistance of the lifting ring block 203, and ensures the smooth horizontal movement of the L-shaped clamping block 201.
[0046] Please refer to Figures 1-2 , the distribution inner diameter of the plurality of limiting blocks 102 is smaller than the maximum diameter of the top of the pile tip, the inner diameter of the connecting sleeve 104 is greater than the diameter of the pipe pile, and the height of the connecting rod 103 is greater than the height of the pile tip.
