Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figures 1-4 This is the first embodiment of the present invention, which provides a portable bridge welding device, including...

[0026] The mobile box 1 has symmetrically distributed sliding openings 13 on its top, which realizes the opening of the sliding openings 13; multiple moving wheels are installed on the bottom of the mobile box 1, which increases the convenience of portable movement of the welding equipment; the front surface of the mobile box 1 is hinged with a box door 11, which facilitates the opening of the box door 11 and increases the convenience of internal maintenance of the mobile box 1.

[0027] The clamping mechanism includes a bearing 14 and a bracket 15 installed on the inner side of the movable box 1, which realizes the addition of bearing 14 and bracket 15. A servo motor 150 is installed on the top of the bracket 15, which increases the support for the servo motor 150. The output shaft of the servo motor 150 is connected to a bidirectional lead screw 7 extending into the bearing 14. When the servo motor 150 is working, it can drive the bidirectional lead screw 7 to rotate. The clamping member 5 is movably set on the movable box 1. An extension 51 is set at the bottom of the clamping member 5, which realizes the addition of extension 51. A threaded hole adapted to the bidirectional lead screw 7 is opened inside the extension 51. When clamping, the servo motor 150 works to drive the bidirectional lead screw 7 to rotate. When the bidirectional lead screw 7 rotates, it drives the two extensions 51 to move closer or further away from each other with the cooperation of the threaded hole. The two extensions 51 move closer or further away from each other, which drives the two clamping members 5 to move closer or further away from each other, thus improving the efficiency of clamping bridge steel structure components.

[0028] The anti-slip protective component includes an anti-slip seat 6 that is detachably mounted on the side surface of the clamping component 5. This adds an anti-slip seat 6, which has anti-slip textures to increase the anti-slip performance of the clamping bridge steel structure component. The added anti-slip seat 6 also helps to increase the protection of the clamping component 5, and can be disassembled and replaced when the anti-slip seat 6 is worn.

[0029] In this embodiment, preferably, it also includes a first groove 61 formed on the side surface of the anti-slip seat 6, and a second groove 52 formed on the side surface of the clamping member 5, and a threaded post 8 extending through the first groove 61 into the interior of the second groove 52, and a nut 520 connected to the threaded post 8, with the nut 520 located inside the second groove 52. When the anti-slip seat 6 and the clamping member 5 are spliced, the threaded post 8 and the nut 520 are used for stabilization, which improves the splicing performance of the anti-slip seat 6 and the clamping member 5. When the nut 520 is unscrewed and the threaded post 8 is removed, the anti-slip seat 6 and the clamping member 5 can be disassembled.

[0030] In this embodiment, preferably, it also includes a plurality of support columns 12 installed on the top of the mobile box 1, thereby increasing the number of support columns 12. A fixing plate 2 is set on the top of the support column 12, and the support column 12 increases the support for the fixing plate 2.

[0031] In this embodiment, preferably, a cylinder 21 is installed on the top of the fixing plate 2, the fixing plate 2 provides support for the cylinder 21, and the output end of the cylinder 21 passes through the fixing plate 2 and is connected to the support plate 3. When the cylinder 21 is working, it can drive the support plate 3 to rise and fall.

[0032] In this embodiment, preferably, a welding head 4 is provided at the bottom of the support plate 3. The welding head 4 is used to weld the bridge steel structure components. The outer side of the welding head 4 is provided with symmetrically distributed lugs. The lugs are connected to the support plate 3 by screws. By using the cooperation of the lugs and screws, the welding head 4 and the support plate 3 are stably spliced ​​together. It is also easy to loosen the screws and disassemble the welding head 4.

[0033] Example 2

[0034] Please see Figures 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment, but differs in that:

[0035] The side surface of the anti-slip base 6 is provided with a limiting block 62, which realizes the addition of the limiting block 62. The side surface of the clamping member 5 is provided with a limiting groove 53 for the limiting block 62 to be inserted, which realizes the opening of the limiting groove 53. The inner side of the limiting groove 53 is equipped with symmetrically distributed baffles 530, which realizes the addition of the baffles 530. When the limiting block 62 is inserted into the limiting groove 53, the limiting block 62 abuts against the two baffles 530. The cooperation of the limiting block 62, the limiting groove 53, and the baffles 530 helps to improve the limitation when the anti-slip base 6 and the clamping member 5 are spliced, and improves the efficiency of splicing the anti-slip base 6 and the clamping member 5.

[0036] It should be noted that the specific structure and working principle of the welding head 4 in this application have been disclosed in the welding equipment for steel structure bridges with publication number CN218575342U;

[0037] The servo motor 150 and cylinder 21 in this application can both be purchased from the market.

[0038] The working principle and usage process of this utility model are as follows: In use, the welding equipment is moved to the construction area by the moving wheels. The bridge steel structure component to be welded is placed at the top center of the moving box 1. The servo motor 150 drives the bidirectional lead screw 7 to rotate. When the bidirectional lead screw 7 rotates, it drives the two extensions 51 to move closer to each other with the help of the threaded hole. The two extensions 51 move closer to each other, which in turn drives the two clamping parts 5 to move closer to each other, thereby clamping the bridge steel structure component to be welded. The cylinder 21 works to drive the support plate 3 to descend. The descent of the support plate 3 drives the welding head 4 to descend, and the welding of the bridge steel structure component is achieved through the welding head 4.

[0039] Although embodiments of the present invention have been shown and described in detail above, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
