[0024] Furthermore, a slot 43 is formed on the connecting rod 41 on one side of the moving block 4 close to the limiting rod 24 , and the slot 43 and the limiting rod 24 are slidably matched with each other.

[0025] Furthermore, two groups of rollers 44 are oppositely provided on the moving block 4, and the rollers 44 are arranged parallel to the connecting rod 41 and the hinge axis of the moving block 4. A cover plate 45 is wrapped around the rollers 44. The moving block 4 is oppositely provided with an outer frame 46 in the direction of rotation of the rollers 44, and a plurality of groups of second slide grooves 47 are oppositely provided on the outer frame 46.

[0026] Furthermore, a through slot 5 is provided at one end of the cover plate 45 away from the roller shaft 44, and two groups of blocks 51 are oppositely provided in the through slot 5. The two groups of blocks 51 are slidably connected to the through slot 5, and a third elastic member 52 is provided between the two groups of blocks 51.

[0027] Furthermore, a mounting block 3 is provided on the side of the connecting rod 41 away from the equipment body 1, the mounting block 3 and the connecting rod 41 are hinged to each other, the first clamping roller 31 is provided on the mounting block 3, the mounting block 3 is provided with a second clamping roller 32, and the second clamping roller 32 is provided on the side of the mounting block 3 away from the axis of the first slide groove 22.

[0028] Specific application examples of the utility model:

[0029] The web clamping device 2 is arranged on the side wall of the equipment body 1. The mounting frame 21 in the web clamping device 2 can be connected to the equipment body 1 through a screw, which is conducive to adjusting the height of the web clamping device 2 so that the web clamping device and the steel part are matched with each other. The second elastic member 23 can be made of a spring. The second elastic member 23 is arranged between the moving block 4 and the side wall of the first slide groove 22. The first slide groove 22 provided on the mounting frame 21 is arranged in a direction away from the side wall of the equipment body 1, so that the moving block 4 moves toward the steel part in the equipment body 1 under the elastic restoring force of the second elastic member 23. It is conducive to the first clamping roller 31 arranged on the moving block 4 to abut against the steel part.

[0030] The first elastic member 42 can be made of a spring. The first elastic member 42 is arranged between the two groups of connecting rods 41. The elastic restoring force of the first elastic member 42 pushes the connecting rod 41 to rotate around the moving block 4, so that the first clamping roller 31 arranged on the connecting rod 41 is mutually abutted and fixed with the part of the steel piece to be welded, thereby ensuring the welding effect. The first clamping roller 31 is connected to the connecting rod 41 through the mounting block 3 so that the first clamping roller 31 can also be mutually horizontally abutted with the web of the steel piece when the connecting rod 41 rotates, which is beneficial to ensuring the clamping and fixing effect. The second clamping roller 32 is arranged on the mounting block 3 to mutually abut and clamp the wing plate of the steel piece, so that the web clamping device 2 not only clamps and fixes the part of the web to be welded, but also clamps and fixes the part of the wing plate to be welded, which is beneficial to keep the steel plates on both sides of the welding part flat.

[0031] The limiting rod 24 disposed at one end of the first slide groove 22 away from the side wall of the device body 1 abuts against the moving block 4, which helps to prevent the moving block 4 from sliding out of the first slide groove 22. The connecting rod 41 is provided with a slot 43 that slides with the limiting rod 24, which helps to prevent the limiting rod 24 from hindering the rotation of the connecting rod 41, resulting in the two sets of connecting rods 41 being unable to rotate to a mutually parallel state.

[0032] The outer frame 46 is arranged on the side of the moving block 4 close to the device body 1. When the two groups of connecting rods 41 are parallel to each other, the two groups of connecting rods 41 are stored in the outer frame 46. The roller shaft 44 is rotatably connected to the moving block 4. A driving assembly can be arranged at one end of the roller shaft 44 to drive the roller shaft 44 to rotate through the operation of the driving assembly. The cover plate 45 can be composed of a plurality of plates hinged to each other. When not in use, the cover plate 45 is wound and stored on the roller shaft 44. When in use, the cover plate 45 is moved away from one end of the roller shaft 44 toward the outer frame 46, so that the cover plate 45 moves toward the outer frame 46 under the restriction of the second slide groove 47, covering the upper and lower openings of the outer frame 46, ensuring that the connecting rod 41 is located in the outer frame 46, thereby completing the storage of the connecting rod 41. The third elastic member 52 can be made of a spring. The third elastic member 52 is arranged between the two groups of blocks 51. The third elastic member 52 pushes the block 51 to move in the through groove 5. When the cover plate 45 moves, the block 51 and the second slide groove 47 are slidably connected with each other. When the cover plate 45 moves to the end of the outer frame 46 away from the moving block 4, the block 51 moves out of the second slide groove 47 and abuts against the outer frame 46 to fix the position of the cover plate 45.
