[0030] It should be noted that the terms used herein are only for the purpose of describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. As used herein, the singular form is intended to include the plural form unless the context clearly indicates otherwise, and it should also be understood that when the terms "comprise" and / or "include" are used in the specification, they indicate the presence of a feature, step, operation, device, component and / or combination thereof.

[0031] As shown in Figures 1 to 5 The track for splicing and welding of prefabricated pipe piles in the embodiment includes a first arc-shaped track 10, a second arc-shaped track 20, a fastener 30 and a jacking piece 40. The second arc-shaped track 20 is spliced with the first arc-shaped track 10 to form a ring-shaped track. The fastener 30 connects the first arc-shaped track 10 and the second arc-shaped track 20. The first arc-shaped track 10 and the second arc-shaped track 20 are both provided with a plurality of jacking pieces 40. The inner side end surface of the jacking piece 40 in the radial direction of the ring-shaped track forms a jacking surface 421 abutting against the prefabricated pipe pile. The jacking piece 40 is movably arranged on the ring-shaped track, so that the position of the jacking surface 421 in the radial direction of the ring-shaped track is adjustable.

[0032] The first arc-shaped track 10 and the second arc-shaped track 20 with the plurality of top pressing pieces 40 are buckled on the lower section prefabricated pipe pile, and then the first arc-shaped track 10 and the second arc-shaped track 20 are fixed together through the fastener 30. Then, the positions of the plurality of top pressing pieces 40 are adjusted, so that the top pressing surfaces 421 of the plurality of top pressing pieces 40 move inward to enable the annular track to be firmly clamped on the lower section prefabricated pipe pile. Then, the movement device is erected on the track, the welding gun is installed on the movement device, the welding wire on the welding gun is aligned with the welding seam, and finally welding is performed. The technical solution of the embodiment can improve the firmness of the track installed on the prefabricated pipe pile, thereby ensuring the welding quality, and can improve the track installation efficiency, thereby improving the overall efficiency of the prefabricated pipe pile splicing welding.

[0033] As shown in the drawings, Figures 1 to 5 In the embodiment, the top pressing piece 40 is a jam nut, the annular track is provided with a threaded hole matched with the jam nut, and the jam nut is arranged in the threaded hole. Specifically, the operator can move the top pressing piece 40 inward along the radial direction by rotating the jam nut, the above structure simplifies the operation steps of the operator, and improves the installation efficiency. In addition, the above structure has the following two advantages: first, it does not occupy the external space of the annular track, thereby not affecting the movement of the movement device provided with the welding gun; second, it is not necessary to additionally provide other transmission mechanisms, thereby reducing the cost. Of course, in other embodiments not shown in the drawings, the top pressing piece 40 can also be a wedge-shaped block that moves up and down. When it is necessary to press, the wedge-shaped block moves upward, the thickness of the wedge-shaped block clamped between the annular track and the prefabricated pipe pile increases, so that the annular track is fixed on the prefabricated pipe pile.

[0034] As shown in the drawings, Figure 5 In the embodiment, the jam nut is provided with a first rotation hole 411 matched with a rotating piece driving the jam nut to rotate on the outer end surface in the radial direction. Preferably, in the embodiment, the first rotation hole 411 is an internal hexagonal rotation hole. The operator first inserts an internal hexagonal wrench into the first rotation hole 411, and then rotates the internal hexagonal wrench, so that the jam nut rotates and moves radially. The above structure is simple and easy to operate. In addition, since the structure matched with the rotating piece is an internal concave structure, it will not protrude outward, thereby not affecting the movement of the movement device.

[0035] As shown in the drawings, Figures 1 to 5 In the embodiment, the jam nut includes a screw body 41 and a top pressing cap 42 arranged at the end of the screw body 41, the cross-sectional area of the top pressing cap 42 is greater than that of the screw body 41, the screw body 41 is arranged in the threaded hole, and the end surface of the top pressing cap 42 forms the top pressing surface 421. The above structure can increase the pressing area of the top pressing surface 421, so that the track can be more firmly fixed on the prefabricated pipe pile.

[0036] As shown in Figures 1 to 5 the present embodiment, the plurality of tightening members 40 are uniformly arranged along the length direction of the first arc-shaped track 10. The plurality of tightening members 40 are uniformly arranged along the length direction of the second arc-shaped track 20. The above structure makes the outward abutting force on the annular track uniform in the circumferential direction, so that the annular track can be firmly installed on the precast pipe pile. Of course, in the embodiment not shown in the figure, only the plurality of tightening members 40 can be uniformly arranged along the length direction of the first arc-shaped track 10, or only the plurality of tightening members 40 can be uniformly arranged along the length direction of the second arc-shaped track 20.

[0037] As shown in Figure 2 and Figure 3 the present embodiment, the first arc-shaped track 10 includes a first arc-shaped track body 11 and a first connecting sheet 12 arranged at both ends of the first arc-shaped track body 11, and the second arc-shaped track 20 includes a second arc-shaped track body 21 and a second connecting sheet 22 arranged at both ends of the second arc-shaped track 20. The corresponding first connecting sheet 12 and the second connecting sheet 22 are arranged in a superposed manner and connected by a connecting screw, and the connecting screw forms a fastener 30. The above structure is simple and easy to assemble.

[0038] In the present embodiment, the connecting screw is provided with a second rotating hole on the outer side end surface in the radial direction, which cooperates with a rotating member for driving the rotation of the connecting screw. In addition, the connection is made by using the above structure, so that the fastener 30 as a whole does not protrude outside the track, so as not to affect the movement of the movement device.

[0039] As shown in Figure 2 and Figure 3 the present embodiment, the first arc-shaped track 10 and the second arc-shaped track 20 have the same structure, in which the outer side surface of one of the first connecting sheets 12 is on the same circle as the outer side surface of the first arc-shaped track body 11, and a first insertion slot for inserting the corresponding second connecting sheet 22 is formed between the first connecting sheet 12 and the end of the first arc-shaped track body 11. The inner side surface of the other first connecting sheet 12 is on the same circle as the inner side surface of the first arc-shaped track body 11, and a second insertion slot for inserting the corresponding second connecting sheet 22 is formed between the first connecting sheet 12 and the end of the first arc-shaped track body 11. The above structure makes the structure of the first arc-shaped track 10 and the second arc-shaped track 20 universal, so as to facilitate production and processing and reduce production cost.

[0040] As shown in Figure 4 the present embodiment, the first connecting sheet 12 and the corresponding second connecting sheet 22 are connected by a plurality of connecting screws. The above structure makes the connection of the first arc-shaped track 10 and the second arc-shaped track 20 more reliable.

Since the track has the advantage of good firmness, the prefabricated pipe pile splicing and welding device having the track has the advantage of high welding quality. In addition, since the track has the advantage of high installation efficiency, the prefabricated pipe pile splicing and welding device having the track has the advantage of high welding efficiency. It should be noted that the welding robot 60 comprises a movement mechanism and a welding gun, and the movement mechanism adjusts the circumferential movement and the up-down movement of the welding gun, so as to form a regular, neat and full weld.
