[0030] In this embodiment, as shown in Figure 2 Figure 4 As shown, the other side inclined surface of the inner wall of the pressure groove plate 4 is fixedly installed with a staggered linkage assembly, which comprises: a sleeve pressing column 11 slidingly installed at the other side inclined surface of the inner wall of the pressure groove plate 4, one end of the sleeve pressing column 11 is fixedly connected with a pressing strip 12; an inclined arc block 13 is fixedly installed at the top end of the pressing strip 12, the inclined arc block 13 is used for positioning and fixing the inclined surface of the outer wall of the bent steel frame 15; a bottom arc block 14 is fixedly connected to the lower surface of the inclined arc block 13, the bottom arc block 14 is used for moving and inserting at the outer wall bottom position of the bent steel frame 15, the outer wall of the welding positioning frame 1 is fixedly connected with a groove plate 31, and the inner wall of the groove plate 31 is fixedly connected with a sliding rod 32; the inner walls of the sleeve pressing column 11 and the sleeve rod 5 are slidingly connected with the sliding rod 32, and the sliding rod 32 penetrates through the sleeve pressing column 11 and the bent steel frame 15.

[0031] In the embodiment, as shown in Figure 5 Figure 7 The longitudinal linkage mechanism comprises: a springy pull rope 17, the bottom end of which is fixedly connected to the upper surface of the linkage block 16, the outer wall of the springy pull rope 17 is slidably connected with a stepped plate 18, and the stepped plate 18 is fixedly connected with the welded positioning frame 1; an inclined pressing strip 19, which is fixedly arranged at the top end of the springy pull rope 17, one end of the inclined pressing strip 19 is fixedly connected with a vertical pressing strip 20, one side of the vertical pressing strip 20 is provided with a spacing block 21, the spacing block 21 is arranged in the gap between the vertical steel frame 10 and the inclined steel frame 9, one side of the spacing block 21 is fixedly connected with an inclined arc plate 22, and the inclined arc plate 22 is fixedly connected with the inclined pressing strip 19; and an inclined supporting strip 23, which is fixedly connected with the other end of the inclined pressing strip 19. One side of the inclined pressing strip 19 is fixedly connected with a sleeving block 24, the inner wall of the sleeving block 24 penetrates through a slidingly connected guide rod 27, the guide rod 27 is fixedly connected with the welded positioning frame 1; one side of the sleeving block 24 is fixedly connected with an elastic sheet 25, one end of the elastic sheet 25 is fixedly arranged with a supporting block 26, and the supporting block 26 is fixedly connected with the welded positioning frame 1. When the pressing groove plate 4 moves downward, the linkage block 16 moves downward synchronously, the springy pull rope 17 slides along the outer wall of the arc-shaped block 28, the inclined pressing strip 19 starts to longitudinally press the vertical pressing strip 20 on the outer wall of the vertical steel frame 10 to longitudinally position and fix the vertical steel frame 10, the inclined pressing strip 19 drives the inclined arc plate 22 to move forward and is inserted into the gap between the vertical steel frame 10 and the inclined steel frame 9, the inclined arc plate 22 is longitudinally pressed on the outer wall of the inclined steel frame 9, the inclined pressing strip 19 drives the inclined supporting strip 23 to move forward, the inclined supporting strip 23 is obliquely pressed on the outer wall of the bent steel frame 15 to obliquely position and fix the outer wall of the bent steel frame 15, and meanwhile, the inclined pressing strip 19 drives the sleeving block 24 to move forward to ensure that the sleeving block 24 moves forward along the outer wall of the guide rod 27, the supporting block 26 supports the elastic sheet 25, and the elastic sheet 25 provides elastic stretching operation for the sleeving block 24. The longitudinal synchronous positioning and fixing of the inclined steel frame 9, the vertical steel frame 10 and the bent steel frame 15 are realized, the positioning and fixing welding is more efficient, and the welding stability is higher.

[0032] In the embodiment, as shown in Figure 6 The upper surfaces of the inclined arc plate 22 and the inclined supporting strip 23 are inclined surfaces, the outer wall of the springy pull rope 17 is slidably arranged with an arc-shaped block 28 at the position on the side of the stepped plate 18, and the lower surface of the arc-shaped block 28 is fixedly connected with the welded positioning frame 1. The springy pull rope 17 slides along the outer wall of the arc-shaped block 28 to reduce the abrasion of the outer wall of the springy pull rope 17.

[0033] In the embodiment, as shown in Figure 8 ​As shown, a controller 29 is installed on the upper surface of the welding positioning frame 1 near its central position. A battery 30 is fixedly connected to one side of the outer wall of the controller 29. The electric cylinder 2 and the pressure sensor 3 are both electrically connected to the controller 29, and the controller 29 is fixedly connected to the battery 30. This allows the controller 29 to be powered by the battery 30, enabling the controller 29 to start the electric cylinder 2. The electric cylinder 2 is then shut off by the controller 29 when the pressure value sensed by the pressure sensor 3 matches the pressure value set by the controller 29.

[0034] The working principle of the welding device for the insert-plate type steel bracket for cast-in-place highway beams of the present invention is as follows: First, when the present invention is installed, the bottom ends of the inclined steel frame 9, the vertical steel frame 10, and the bent steel frame 15 are all pre-embedded and fixed with the concrete of the highway cast-in-place beam. Then, the inclined steel frame 9, the vertical steel frame 10, and the bent steel frame 15 need to be contact welded. Then, the welding positioning frame 1 is placed in the highway cast-in-place beam trough, and the lower surface of the welding positioning frame 1 is placed at the bottom of the inner wall of the highway cast-in-place beam trough. The welding positioning frame 1 is positioned at the outer wall of the vertical steel frame 10 and the outer wall of the inclined steel frame 9, and the lower surface of the welding positioning frame 1 is attached to the outer wall of the bent steel frame 15.

[0035] Secondly, during the staggered synchronous positioning welding of this invention, the battery 30 powers the controller 29, which in turn activates the electric cylinder 2. The output of the electric cylinder 2 pushes the pressure sensor 3 downward, which in turn moves the pressure plate 4 downward. The pressure plate 4 then moves the sleeve rod 5 to the right, guiding it to the right along the outer wall of the slide rod 32. Simultaneously, the welding positioning frame 1 supports the groove plate 31, which in turn supports the slide rod 32. The sleeve rod 5 moves steadily to the right, causing the connecting strip 6 to move to the right. The connecting strip 6 then moves the inclined pressure block 7 to the right, which laterally presses against the inclined surface of the outer wall of the inclined steel frame 9 while in an inclined state. At the same time, the connecting strip 6 moves the vertical pressure plate 8 to the right, which laterally presses against the outer wall of the vertical steel frame 10. This achieves lateral staggered synchronous positioning and fixation of the inclined steel frame 9 and the vertical steel frame 10.

[0036] Simultaneously, when the present invention performs misalignment linkage, the downward movement of the pressure plate 4 will drive the sleeve pressure column 11 to move to the left. The sleeve pressure column 11 moves to the left along the outer wall of the slide rod 32, and at the same time, the sleeve pressure column 11 drives the pressure strip 12 to move to the left. The pressure strip 12 causes the inclined arc block 13 to move to the left. The inclined arc block 13 presses against the inclined surface of the outer wall of the bent steel frame 15 in an inclined state. At the same time, the inclined arc block 13 drives the bottom arc block 14 to move to the left. The bottom arc block 14 contacts the bottom position of the outer wall of the bent steel frame 15. In this way, the inclined arc block 13 and the bottom arc block 14 can be misaligned to position and fix the outer side and bottom of the outer wall of the bent steel frame 15.

[0037] Simultaneously, during longitudinal linkage, when the pressure plate 4 moves downward, it causes the linkage block 16 to move downward synchronously. The linkage block 16 pulls the bottom end of the elastic rope 17 downward, causing the elastic rope 17 to slide along the outer wall of the arc-shaped block 28 and move forward along the outer wall of the step plate 18. This causes the elastic rope 17 to move the inclined pressure strip 19 forward, which in turn causes the vertical pressure strip 20 to longitudinally press against the outer wall of the vertical steel frame 10, thus longitudinally positioning and fixing the vertical steel frame 10. Furthermore, the inclined pressure strip 19 causes the inclined arc plate 22 to move the spacer block 21 forward, and the spacer block 21 is guided and inserted into the angled gap between the vertical steel frame 10 and the inclined steel frame 9. At the same time, the inclined arc plate 22 longitudinally presses against the outer wall of the inclined steel frame 9, achieving inclined longitudinal positioning and fixing of the inclined steel frame 9. At the same time, the inclined pressure strip 19 drives the inclined support strip 23 to move forward. The inclined support strip 23 is inclined and pressed against the inclined surface of the outer wall of the bent steel frame 15. In this way, the inclined support strip 23 is inclined and fixed to the outer wall of the bent steel frame 15. At the same time, the vertical steel frame 10, the inclined steel frame 9, and the bent steel frame 15 are all fixed to the side of the step plate 18.

[0038] Simultaneously, the inclined pressure bar 19 drives the sleeve block 24 to move forward. The sleeve block 24 moves forward along the outer wall of the guide rod 27, and is supported by the support block 26 through the welding positioning frame 1. The support block 26 supports the spring piece 25, and the spring piece 25 provides elastic tension to the sleeve block 24. At the same time, the elastic pull rope 17 can also deform and stretch itself, thus ensuring that the linkage block 16 moves down, so that the vertical pressure bar 20, the inclined arc plate 22, and the inclined support bar 23 move forward longitudinally in sync. When the pressure value sensed by the pressure sensor 3 is the same as the pressure value set by the controller 29, the electric cylinder 2 is shut off by the controller 29. In this way, the inclined steel frame 9, the vertical steel frame 10, and the bent steel frame 15 are simultaneously positioned and fixed in a horizontally staggered manner, and can also be positioned and fixed in a longitudinally synchronized manner. Then, the edge welding is performed on the connection between the inclined steel frame 9, the vertical steel frame 10, and the bent steel frame 15 using a welding torch.
