[0002] Tower feet are positioning components installed at the connection between the tower base and the tower body. Their main function is to ensure the accurate installation position of the tower body and provide stable support, guaranteeing the stability and safety of the overall structure. Tower feet are welded assemblies and are the main supporting components of the entire power transmission tower structure. Therefore, the welding quality and the stability of their own structure affect the structural stability and service life of the entire power tower. Tower feet consist of a base plate and a cross-shaped connecting plate fixed to the base plate. During use, the cross-shaped connecting plate is connected to the tower rod. The base plate and the cross-shaped connecting plate typically require welding equipment for welding and fixing.

[0003] In the prior art, for example, patent application number CN202321974429.1 discloses a welding area in the middle of the top of the welding platform to facilitate the placement of the tower legs. At least two fixing plates are provided on the welding platform around the welding area, and fixing bolts are screwed on both ends of the fixing plates. At least four threaded holes that mate with the fixing bolts are provided on the welding platform. The tower legs are fixedly connected to the welding area of ​​the workbench by using fixing plates and bolts. This method is not suitable for fixing tower legs of multiple sizes. Moreover, once the tower legs are fixed by the fixing plates, their position cannot be moved and their angle cannot be adjusted. Furthermore, since there are many parts to be welded and many welding points, the welding machine needs to be moved constantly between various positions, resulting in reduced welding efficiency.

[0040] The first guide frame 411 is connected above the rotating table body 31. The first guide frame 411 has a cavity as a sliding cavity for the first slider. The first lead screw is rotatably connected in the sliding cavity, and the first slider is threadedly connected to the first lead screw. By rotating the first lead screw, the first slider can move along the first lead screw. The first guide frame 411 has a first groove on its upper part. The first slider can move along the first groove, and one end of the first slider can extend out of the first groove to facilitate connection with the positioning component 43, so that the positioning component 43 can be slidably connected to the first guide frame 411.

[0041] In a preferred embodiment, the first guide frame 411 further includes a first manual wheel 412, which is connected to one end of the first lead screw. The first manual wheel 412 can be rotated to rotate the first lead screw, so that the first slider moves along the first lead screw.

[0042] To rotate the first lead screw, a first manual wheel 412 is connected to the outside of the first guide frame 411 body. The first manual wheel 412 is connected to the first lead screw. By rotating the first manual wheel 412, the operator can drive the first slider to move along the first groove. The two ends of the first lead screw are provided with threaded sections with opposite directions of rotation, and the two ends of the first lead screw are respectively connected to the first slider. In use, when the first manual wheel 412 is operated, the first sliders on both sides can move relative to each other, so as to be suitable for positioning tower feet of different sizes, so that the positioning components 43 connected to the first sliders on both sides can abut against and connect to the four corners of the tower foot.

[0043] In a preferred embodiment, the second guide frame 413 includes a second guide frame 413 body, a second lead screw, and a second slider. The second guide frame 413 body has a cavity, and a second groove communicating with the cavity is opened on the top of the second guide frame 413 body. The second lead screw is rotatably connected to the inside of the second guide frame 413 body corresponding to the second groove. The second slider is slidably connected to the second lead screw, and the second slider can extend out of the second groove.

[0044] The second guide frame 413 is connected above the rotating table body 31. The second guide frame 413 has a cavity as a sliding cavity for the second slider. The second lead screw is rotatably connected in the sliding cavity, and the second slider is threadedly connected to the second lead screw. By rotating the second lead screw, the second slider can move along the second lead screw. The second guide frame 413 has a second groove on its upper part. The second slider can move along the second groove, and one end of the second slider can extend out of the second groove to facilitate connection with the positioning component 43, so that the positioning component 43 can be slidably connected to the second guide frame 413.

[0045] In a preferred embodiment, the sliding assembly 42 includes a first sliding block 421 and a second sliding block 422, which are connected to a second lead screw. The first sliding block 421 and the second sliding block 422 are provided with threaded holes 8 that can be connected to the through holes of the tower feet.

[0046] In addition to the slidable connection of the positioning component 43, the second guide frame 413 is also connected to a sliding component 42.

The first sliding block 421 and the second sliding block 422 are connected to both sides of the second lead screw. The two sides of the second lead screw have helical segments with opposite directions of rotation. Therefore, the relative movement of the first sliding block 421 and the second sliding block 422 on both sides can be achieved by rotating the second manual wheel 414 described below, thereby adjusting the distance between the first sliding block 421 and the second sliding block 422. Since the first sliding block 421 and the second sliding block 422 are respectively provided with threaded holes 8, when the first sliding block 421 and the second sliding block 422 move relative to each other until the threaded hole 8 corresponds to the through hole on the base plate of the tower foot, the rotation of the second manual wheel 414 is stopped, and the bolt is inserted into the threaded hole 8 and the through hole to fix the base plate of the tower foot to the first sliding block 421 and the second sliding block 422.

[0047] Furthermore, the first sliding block 421 and the second sliding block 422 are disposed between the second sliders on both sides of the second lead screw; since the positioning component 43 is used to abut and position the four corners of the tower foot, the first sliding block 421 and the second sliding block 422 are bolted to the base plate of the tower foot, and the through hole on the base plate is located on the base plate. In order to prevent movement from causing conflict, the positioning component 43 needs to be disposed outside the first sliding block 421 and the second sliding block 422; therefore, the positioning block 431 is connected to both ends of the first lead screw and is located outside the first sliding block 421 and the second sliding block 422.

[0048] In a preferred embodiment, the second guide frame 413 further includes a second manual wheel 414, which is connected to one end of the second lead screw. The second lead screw can be rotated by rotating the second manual wheel 414, so that the second slider can move along the second lead screw.

[0049] To rotate the second lead screw, a second manual wheel 414 is connected to the outside of the second guide frame 413 body. The second manual wheel 414 is connected to the second lead screw. By rotating the second manual wheel 414, the operator can drive the second slider to move along the second groove. The two ends of the second lead screw are provided with threaded sections with opposite directions of rotation, and the two ends of the second lead screw are respectively connected to the second slider. In use, when the second manual wheel 414 is operated, the two second sliders on both sides can move relative to each other, so as to be suitable for positioning tower feet of different sizes, so that the positioning components 43 connected to the two second sliders on both sides can abut against the four corners of the tower foot.

[0050] In a preferred embodiment, the positioning component 43 includes positioning blocks 431, two positioning blocks 431 are slidably connected to both ends of the first lead screw, and the positioning blocks 431 are connected above the first slider; the side of the positioning block 431 facing the center of the first guide frame 411 has a positioning groove 6 with a V-shaped structure for abutting the tower foot.

[0051] The positioning block 431 has a V-shaped positioning groove 6 on one side facing the center of the first guide frame 411. The V-shaped positioning groove 6 can position the top corner of the rectangular structure of the tower foot, and the two side walls of the positioning groove 6 can abut and connect to the two sides of the top corner.

[0052] In a preferred embodiment, the bottom of the positioning groove 6 has a relief groove 7 that is recessed into the positioning block 431.

[0053] The bottom of the positioning groove 6 is provided with an inwardly recessed clearance groove 7. The clearance groove 7 is lower than the bottom surface of the positioning groove 6. The purpose is to prevent the bottom of the positioning groove 6, which has a V-shaped structure, from interfering with the top corner of the tower foot and causing wear to the top corner of the tower foot.

[0054] In a preferred embodiment, the positioning component 43 further includes a support block 432; the support block 432 includes a support block body 4321 and a clamping block; the support block body 4321 is connected above the positioning block 431, and the clamping block is vertically connected above the support block body 4321, and the clamping block can move relative to the support block body 4321 to position the tower foot.

[0055] A support block 432 is also connected above the positioning block 431. The support block 432 has an L-shaped structure and includes a support block body 4321 connected to the positioning block 431 and a clamping block connected above the support block body 4321. The function of the clamping block is to clamp the connecting plate connected above the base plate. The clamping block can slide relative to the support block body 4321, thereby adjusting the distance between the clamping blocks on both sides of the first guide frame 411 or the clamping blocks on both sides of the second guide frame 413, so as to be suitable for clamping the connecting plates above the tower feet of different sizes.

[0056] The end of the clamping block can have a concave arc structure with an elastic layer on the concave arc surface to wrap around both sides of the connecting plate, preventing wear on the sides of the connecting plate. Alternatively, the end of the clamping block can be movably connected to two relatively moving clamping blocks. The end of the clamping block is rotatably connected to a drive screw, and the two clamping blocks are threaded to both sides of the drive screw. By rotating the screw, the relative distance between the two clamping blocks can be adjusted to clamp connecting plates of different thicknesses. Through the setting of positioning blocks and support blocks, multi-position positioning of the base plate and connecting plate of the tower foot can be achieved, further improving the positioning accuracy of the tower foot, thereby improving welding quality and ensuring welding efficiency.
