[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0032] Reference Figure 1 - Figure 2 The present invention provides an embodiment of an auxiliary welding device for power transmission towers, comprising a machine base 1 supported by support legs distributed at the four corners of the machine base 1. A positioning mechanism is provided on the lower surface of the machine base 1, the positioning mechanism including a moving component and a control component, used to move the entire device and control whether the device is in a moving state. A fixing mechanism is provided on the upper surface of the machine base 1, the fixing mechanism including a clamping component and a transmission component, used to clamp the welding workpiece and transmit power to meet welding requirements.

[0033] Reference Figure 1 , Figure 2 , Figure 4 The fixing mechanism includes a clamping assembly and a transmission assembly. The clamping assembly includes a limiting plate 46. A bottom support frame 45 is fixedly connected to the lower surface of the limiting plate 46. A hollow tube 43 is fixedly connected to the front surface of the limiting plate 46. One end of a connecting spring 44 is fixedly connected to the inner wall of the rear side of the hollow tube 43. A slide rod 42 is fixedly connected to the other end of the connecting spring 44. A clamping block 41 is fixedly connected to the front surface of the slide rod 42. Under the pressure of the workpiece, the clamping block 41 will push the guide rod 35 to move laterally along the inner wall of the hollow tube 43, while simultaneously squeezing the connecting spring 44. Since the reverse force of the connecting spring 44 is applied to the slide rod 42, a greater elastic force is generated, thereby enabling the clamping block 41 to more tightly press the workpiece, ensuring the stability and firmness of the clamping.

[0034] Reference Figure 1 , Figure 2 , Figure 4 The transmission assembly includes a handle 21, with a worm gear 22 fixedly connected to the left end of the handle 21. Rotating the handle 21 causes the worm gear 22 to rotate. A rotating platform 24 is rotatably connected to the inner wall of the bottom of the machine base 1. The rotating platform 24 can rotate. A worm wheel 23 is fixedly connected to the outer wall of the rotating platform 24. An arc-shaped groove 25 is provided on the upper surface of the rotating platform 24. Multiple sets of arc-shaped grooves 25 are symmetrically distributed around the center of the rotating platform 24. A support platform 26 is fixedly connected to the inner wall of the machine base 1. A sliding groove 27 is provided on the upper surface of the support platform 26. Multiple sets of sliding grooves 27 are symmetrically distributed in a "cross" shape around the center of the support platform 26. The rotation of the worm gear 22 causes the rotating platform 24 to rotate, thereby pushing the bottom support frame 45 to move under force.

[0035] Reference Figure 1 , Figure 3 , Figure 5The moving component includes a support base plate 53, with a pressure block 54 fixedly connected to the lower surface of the support base plate 53. The bottom of the machine base 1 is equipped with casters 51. Since casters 51 are existing technology and can be implemented by those skilled in the art, they will not be described in detail in this case. One end of a return spring 52 is fixedly connected to the inner wall of the bottom of the machine base 1, and the other end of the return spring 52 is fixedly connected to the lower surface of the support base plate 53. When the support base plate 53 is subjected to force and moves downward, the pressure block 54 will press down on the pedal on the caster 51 to lock it, thereby fixing the device.

[0036] Reference Figure 1 , Figure 3 , Figure 5 The control assembly includes a control lever 31, with a handle 36 fixedly connected to its upper surface. Holding the handle 36 drives the control lever 31 to move laterally. A fixing block 37 is fixedly connected to the left surface of the control lever 31. The fixing block 37 can be inserted into a fixing slot 38 to position the control lever 31. A guide rod 35 is fixedly connected to the right surface of the control lever 31. A square box 32 is fixedly connected to the right surface of the machine base 1. A sleeve 33 is slidably connected to the left surface of the square box 32. One end of a compression spring 34 is fixedly connected to the inner wall on the right side of the sleeve 33. The other end of the compression spring 34 is fixedly connected to the right surface of the guide rod 35. The guide rod 35 moves laterally along the inner wall of the sleeve 33 under the drive of the control lever 31, while simultaneously compressing the compression spring 34. Due to the reaction force of the compression spring 34 applied to the guide rod 35, the control lever 31 is pressed down, thereby firmly pressing down the control lever 31 and ensuring its positional stability. A fixing slot 38 is provided on the right surface of the machine base 1.

[0037] Reference Figure 1 , Figure 2 , Figure 4 The slide bar 42 passes through and is slidably connected to the front surface of the clamping block 41 to ensure smooth movement of the slide bar 42. The handle 21 passes through and is rotatably connected to the right surface of the machine base 1. The worm 22 and the worm wheel 23 mesh. The worm 22 and the worm wheel 23 are both existing technologies and can be implemented by those skilled in the art. Since they are existing technologies, they will not be described in detail in this case. The rotation of the worm 22 can drive the worm wheel 23 to rotate, but the worm wheel 23 cannot drive the worm 22 to rotate. The support platform 26 is located above the rotating platform 24.

[0038] Reference Figure 1 , Figure 3 , Figure 5The support base plate 53 is slidably connected to the outer wall of the machine base 1. The support base plate 53 can slide up and down along the outer wall of the machine base 1. The control rod 31 is slidably connected to the upper surface of the support base plate 53. The control rod 31 can slide along the groove of the support base plate 53. The guide rod 35 passes through and is slidably connected to the left surface of the sleeve 33 to ensure that the guide rod 35 moves smoothly. The fixed slot 38 is divided into upper and lower slots, which are used to control the two states of the device: moving and stationary.

[0039] Working principle: When using this device, turn the handle 21 to drive the worm 22 to rotate. The worm wheel 23 and the worm 22 rotate through gear meshing, which drives the rotating platform 24 to rotate. When the rotating platform 24 rotates, it will drive the arc groove 25 to move. The support platform 26 and the slide 27 remain stationary. The moving arc groove 25 will then squeeze the bottom support frame 45 and move it radially along the slide 27 until the clamping block 41 compacts the workpiece.

[0040] During the movement of the device, gripping the handle 36 drives the control lever 31 to move along the left and right axial direction. The fixing block 37 is pulled out from the fixing slot 38 above. Gripping the handle 36 again drives the control lever 31 to move downward, which in turn drives the sleeve 33, compression spring 34, and guide rod 35 to move downward. As a result, the bottom support frame 45 moves downward along the outer wall of the machine base 1, which drives the pressure block 54 to press down on the universal wheel 51, triggering the brake and stopping the entire device from moving. Similarly, the same method can be used to release the restriction on the control lever 31. Then, the control lever 31 and the pressure block 54 are moved upward to release the restriction on the universal wheel 51, allowing the device to move flexibly.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
