[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0025] like Figures 1 to 4 As shown, this embodiment provides a cage welding device, including a first welding wheel assembly 1, a second welding wheel assembly 2, a main frame 3, a rotating plate 4, and an electrode assembly 5. The rotating plate 4 is rotatably mounted on the main frame 3 and is rotatably installed in the through hole of the main frame 3 via bearings, allowing the rotating plate to rotate relative to the main frame 3. The electrode assembly 5 is mounted on the main frame 3 and includes a guide plate 51 and a fixed electrode 52. The guide plate 51 has several longitudinal rib holes 510 along the outer periphery of the fixed electrode 52 for the longitudinal ribs of the reinforcing cage to pass through. The surface of the guide plate 51 has a first guide groove 511 and a second guide groove 512 surrounding the fixed electrode. The first and second guide grooves are closed loop grooves, and the guide plate is made of insulating material. The first welding wheel assembly 1 and the second welding wheel assembly 2 are mounted on the rotating plate 4 and are respectively connected to the first guide groove 511 and the second guide groove 512. The fixed electrode 52 has a short side 521 and a long side 522. The first welding wheel assembly 1 is correspondingly arranged with respect to the short side 521, and the second welding wheel assembly 2 is correspondingly arranged with respect to the long side 522. In the above technical solution, the rotating plate 4 rotates clockwise, and the long and short sides of the reinforcing cage are respectively rolled welded by two welding wheel assemblies arranged circumferentially. This method is applicable to sheet pile reinforcing cages with a certain length-to-width ratio, and the welded reinforcing cage is firm and has high strength, thus improving the production quality of sheet piles.
[0026] Furthermore, the fixed electrode 52 has a groove 523, which is provided on the short side 521 and the long side 522. The groove 523 is provided in correspondence with the longitudinal reinforcement hole 510, so that the reinforcing bar can pass through the longitudinal reinforcement hole and abut against the groove 523 to obtain support.
[0027] Further, the first welding wheel assembly 1 comprises a first slide column 11, and the second welding wheel assembly 2 comprises a second slide column 21, the first slide column 11 and the second slide column 21 are arranged in the first guide slot 511 and the second guide slot 512 respectively, by arranging the first slide column and the second slide column, the first welding wheel assembly and the second welding wheel assembly can be guided to move along the direction of the guide slot, the first slide column 11 and the second slide column 21 are the same in structure.
[0028] Further, the first guide slot 511 is wider than the second guide slot 512, and the first guide slot 511 is shallower than the second guide slot 512, the first guide slot is wider and shallower, and the second guide slot is narrower and deeper, so that the slide column can be prevented from entering the corresponding guide slot.
[0029] Further, the first welding wheel assembly 1 comprises a first pressing wheel 12, and the second welding wheel assembly 2 comprises a second pressing wheel 22, the first pressing wheel 12 abuts against the long side part 522, and the second pressing wheel 12 abuts against the short side part 521. Due to the limiting effect of the guide slot on the slide column, the first pressing wheel of the first welding wheel assembly only abuts against two long side parts of the fixed electrode, and the second pressing wheel of the second welding wheel assembly only abuts against two short side parts of the fixed electrode. The pressing wheel presses the ring rib against the longitudinal rib, and the pressing wheel and the fixed electrode are both made of conductive material to perform the roll welding work by electrification.
[0030] Further, the first welding wheel assembly 1 comprises a first supporting rod 13 and a first air cylinder 14, the first supporting rod 13 is hinged to the rotating plate 4, and the two ends of the first supporting rod 13 are connected with the first pressing wheel 12 and the telescopic rod of the first air cylinder 14 respectively.

The piston rod of the air cylinder can drive the supporting rod to deflect, so that the pressing wheel presses the ring rib against the longitudinal rib.
[0031] Further, the first guide slot 511 has a first symmetry axis 10, the second guide slot 512 has a second symmetry axis 20, and the first symmetry axis 10 intersects with the second symmetry axis 20 at the center position of the fixed electrode.

In the embodiment, the plate pile with the cross-sectional aspect ratio a / b (greater than 1), the central angle of the two copper pressing wheels is preferably (2d / L)-(2b / L), in the formula, the unit is radian, d is the diameter of the pressing wheel, L is the length of the diagonal line, and b is the length of the short side. The rotating plate rotates in the clockwise direction, when the pressing wheel of the first welding wheel assembly just passes the short side of the steel reinforcement cage, the second welding wheel assembly completes the welding of the short side of the steel reinforcement cage, and the corresponding central angle is 2d / L; or, when the pressing wheel of the first welding wheel assembly just passes the short side of the steel reinforcement cage, the second welding wheel assembly starts to weld the short side of the steel reinforcement cage, and the corresponding central angle is 2b / L.
