[0023] In order to make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. The components of the embodiments of the present utility model usually described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed present utility model, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the scope of protection of the present utility model.

[0025] Please refer to Figures 1-5 , the present utility model provides a butt welding device for a bridge crane bridge, which includes a bottom plate 1, and a welding device for welding a welded part is slidably arranged on the bottom plate 1. The welding device includes a sliding seat 2 slidably arranged on the bottom plate 1, a mounting bracket 3 arranged on the sliding seat 2 in a lifting manner, and a welding assembly slidably arranged on the mounting bracket 3. The welding assembly includes a connecting plate 4 slidably connected to the mounting bracket 3, and a welding torch 5 arranged on the connecting plate 4. The welding torch 5 is connected to the controller 6 through a power cord 18.

[0026] As Figure 1 , Figure 2 shown, a chute 7 is arranged on the bottom plate 1, and a first roller 8 rotatably arranged in the chute 7 is arranged at the bottom of the sliding seat 2. Two sets of the chute 7 and the first roller 8 are respectively arranged on both sides of the bottom plate 1. By driving a transmission shaft through a motor, the two sets of rollers are driven to rotate, so as to realize the lateral movement of the welding device on the bottom plate 1.

[0027] As Figure 5As shown, a first screw rod 9 is rotatably arranged in the slide 2, and the first screw rod 9 is threadedly connected to the mounting frame 3. The first screw rod 9 is driven by a motor, and the mounting frame 3 is driven to slide up and down by rotating the first screw rod 9 to adjust the height of the welding gun 5. One or two first screw rods 9 can be provided. In this embodiment, two first screw rods 9 are provided, which are distributed on both sides of the slide slot 7. The motors of the two first screw rods 9 are synchronously controlled by the controller 6. Under the action of the two first screw rods 9, the mounting frame 3 is more stable during the up and down movement.

[0028] In this embodiment, two connecting plates 4 and welding guns 5 are provided, which are distributed on both sides of the mounting frame 3. The two welding guns 5 can improve the welding efficiency. The two connecting plates 4 can slide independently on the mounting frame 3 to achieve independent movement of the two welding guns 5. Specifically, Figure 4 As shown, two second screw rods 10 are rotatably arranged in the mounting frame 3, and the two second screw rods 10 are correspondingly threadedly connected to the two connecting plates 4. A driving motor 11 is slidably arranged on the mounting frame 3, and the output end of the driving motor 11 is equipped with a driving wheel 12, and the driving wheel 12 can be selectively connected to the two second screw rods 10. The driving motor 11 is slidable through the electric telescopic rod, and the driving wheel 12 is a gear, which can be respectively connected to the two second screw rods 10 through the gear transmission assembly. The specific operation is that the driving motor 11 is driven to move by the electric telescopic rod, and then the driving wheel 12 is driven to move, and finally the gear transmission assembly between the driving wheel 12 and the two second screw rods 10 is selectively transmitted and disconnected, so as to adjust the front and rear positions of the two welding guns 5 separately.

[0029] like Figure 1 As shown, a supporting device for placing welded parts is also slidably provided on the bottom plate 1. The supporting device includes a top plate 13 slidably connected to the bottom plate 1. The bottom plate 1 is used to place some welded parts. In order to realize the movement of the welded parts on the top plate 13, as shown in FIG. Figure 3 As shown, second rollers 14 that are in sliding contact with the bottom plate 1 are provided on both sides of the top plate 13. The movement of the top plate 13 is driven by an electric telescopic rod, and the second rollers 14 ensure stable sliding between the top plate 13 and the bottom plate 1. The movement of the top plate 13 enables the welded parts to move and come into contact with each other, thereby facilitating welding operations. Furthermore, the support device also includes a first support block 15 that is slidably disposed on both sides of the top plate 13. The first support block 15 is configured in two and is slidably connected to the top plate 13. The first support block 15 can carry another part of the welded parts, and through its movement, mutual contact between the welded parts is achieved. In addition, the support device also includes two second support blocks 16 that are slidably disposed at one end of the bottom plate 1 away from the top plate 13, and the second support block 16 can carry another part of the welded parts. As shown Figure 3As shown, the movement of the second support block 16 can also be achieved by the transmission of the motor and the lead screw. At the same time, gaskets 17 are arranged on the surfaces of the top plate 13, the first support block 15 and the second support block 16 to provide a certain degree of protection for the welded parts. Through the coordinated action of the top plate 13, the first support block 15 and the second support member, effective support and contact between different welded parts can be achieved. When used in cooperation with the welding device, it can meet the requirements of various welding positions, thereby improving the convenience of operation.
