[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0023] like Figures 1 to 5As shown, a truss welding rotation auxiliary device includes an auxiliary support device and a rotation support device. The rotation support device includes a first movable base 6, a motor support 5, a reduction motor, and a clamping and fixing mechanism. The motor support 5 is fixed on the first movable base 6, and the reduction motor is fixed on the motor support 5. The output end of the reduction motor is connected to the clamping and fixing mechanism. The auxiliary support device includes a second movable base 1, a support frame 2, and a clamping and fixing mechanism. The support frame 2 is fixed on the second movable base 1, and the clamping and fixing mechanism is rotatably mounted on the support frame 2. The device also includes a track 4, on which both the first movable base 6 and the second movable base 1 are placed. In this embodiment, when welding the truss, the two ends of the truss are supported by an auxiliary support device and a rotating support device, so that the truss is suspended in the air, which facilitates welding. During clamping, the truss is clamped by a clamping and fixing mechanism. During the welding process, the truss needs to rotate. The geared motor on the rotating support device drives the clamping and fixing mechanism to rotate, thereby driving the truss to rotate. The clamping and fixing mechanism on the auxiliary support device rotates with the truss. This allows the angle of the truss to be adjusted according to the needs of the welder. The geared motor is controlled by a control cabinet, which can adjust the rotation angle.

[0024] Furthermore, the clamping and fixing mechanism includes a turntable 3, a rotating shaft 9, and clamping mechanisms 7. The rotating shaft 9 is coaxially and fixedly connected to the turntable 3. Multiple clamping mechanisms 7 are arranged on the turntable 3. The rotating shaft 9 of the auxiliary support device is rotatably connected to the support frame 2. The rotating shaft 9 of the rotary support device is rotatably connected to the motor support 5 and connected to the output end of the geared motor. In this embodiment, in order to fix the truss, three clamping mechanisms 7 are provided on the turntable 3 for fixing the triangular truss. During fixing, the clamping mechanisms 7 of the triangular truss are inserted into the steel tubes of the triangular truss to clamp the truss. The truss is clamped between the auxiliary support device and the rotary support device.

[0025] Furthermore, the clamping mechanism 7 includes a mounting plate 10, a pull rod 12, and clamping blocks 11. At least three clamping blocks 11 are provided. One end of the pull rod 12 is provided with a conical push block 20. A slider is provided on the end face of the clamping block 11. The mounting plate 10 is provided with a plurality of radially arranged sliding grooves 13. The sliders are slidably disposed in the sliding grooves 13 one by one. The inner side of the slider is provided with a conical surface, which is slidably connected to the outer wall of the conical push block 20. In this embodiment, clamping blocks 11 are slidably mounted on the mounting plate 10. Four clamping blocks 11 are arrayed on the outside of the tie rod 12 to form a cylindrical tension rod. When fixing the truss, the tension rod is inserted into the steel pipe of the truss, and then the tie rod 12 is pulled. At this time, the conical push block 20 set at one end of the tie rod 12 abuts against the clamping block 11 and pushes the clamping block 11 along the slide groove 13. In this way, the outer diameter of the tension rod expands, thereby clamping the steel pipe of the truss and preventing the steel pipe from shaking. Multiple clamping mechanisms 7 clamp the steel pipe one by one to fix the truss. The slider is cylindrical, so that it can only slide along the slide groove 13 and will not fall out of the slide groove 13.

[0026] Furthermore, a return spring 14 is provided in the slide groove 13, the return spring 14 abuts against the slider, and an end cap 15 is provided on the mounting plate 10 to limit the return spring 14 in the slide groove 13. In this example, in order to disassemble the truss after welding, a return spring 14 is installed in the slide 13. When disassembling, the pull rod 12 is pushed in the opposite direction, and under the action of the return spring 14, the clamping block 11 is pushed along the slide 13 towards the center of the mounting plate 10. This reduces the outer diameter of the tension rod formed by the clamping block 11, allowing the tension rod to be pulled out of the steel pipe of the truss. When removing the truss, the clamping mechanism 7 on the same clamping and fixing mechanism is first released, and then the auxiliary support device or the rotating support device is pushed along the track 4 to separate the clamping mechanism 7 on one side from the truss. The first moving base 6 and the second moving base 1 are the moving trolleys of the track 4, which are equipped with brakes. During disassembly, a support device can be placed between the auxiliary support device and the rotating support device to support the truss, preventing the truss from falling directly to the ground after disassembly on one side and damaging the clamping mechanism 7 on the other side.

[0027] Furthermore, one end of the mounting plate 10 is provided with a stud 16, the stud 16 is threadedly connected to a threaded sleeve 17, the threaded sleeve 17 is provided with a pressure plate 18, the stud 16 is provided with a central hole, and a nut sleeve 20 is provided in the central hole of the stud 16. One end of the pull rod 12 is provided with a thread, the pull rod 12 is threadedly connected to the nut sleeve 20, and one end of the pull rod 12 is provided with a handle 19. The turntable 3 is provided with radially arranged sliding grooves 8 corresponding to the number of clamping mechanisms 7. Sliding surfaces are cut on both sides of the stud 16, and the stud 16 slides in cooperation with the sliding grooves 8. The clamping mechanism 7 is fixed on the turntable 3 by the cooperation of the threaded sleeve 17 and the mounting plate 10. In this embodiment, in order to fix the clamping mechanism 7 on the turntable 3, a stud 16 is provided on the mounting plate 10. Sliding surfaces are cut on both sides of the stud 16, so that the stud 16 can slide in the sliding groove 8. Adjusting the position of the clamping mechanism 7 can accommodate trusses of different sizes. After adjusting the position, tighten the threaded sleeve 17. The pressure plate 18 on the threaded sleeve 17 and the mounting plate 10 abut against the turntable 3, thus fixing the clamping mechanism 7 on the turntable 3. Rotating the pull rod 12 so that the pull rod 12 and the nut sleeve 20 rotate relative to each other can make the pull rod 12 move axially, thereby driving the conical push block 20 to move.

[0028] Furthermore, the outer surface of the clamping block 11 is provided with multiple steps. In this embodiment, in order to clamp truss steel pipes with different inner diameters, multiple steps are provided on the outer side of the clamping block 11. The resulting tensioning rod is a stepped shaft. For steel pipes with different inner diameters, the insertion depth of the tensioning rod into the steel pipe is different, corresponding to different steps, thus adapting to steel pipes with different inner diameters.

[0029] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
