[0021] This utility model provides, for example Figures 1-4 The diagram shows a special welding fixture for the angle steel tower feet of a power transmission tower, including an operating platform 1, with support columns 3 fixedly connected to the four corners of the lower surface of the operating platform 1.

[0022] The top of the operating platform 1 is equipped with a first positioning component, which includes two first positioning plates 2. The first positioning plates 2 are fixedly connected to the operating platform 1, and a fixing groove for placing a steel plate is formed between the two first positioning plates 2. In actual use, the angle steel tower legs of the transmission tower are inserted into the fixing groove with steel plates. Rubber blocks or other structures can be installed in the fixing groove to improve the stability of the steel plate placement. This can be adjusted according to the specific usage.

[0023] The operating table 1 is equipped with a second positioning assembly for welding two steel plates. The second positioning assembly includes two second positioning plates 4, which are fixedly connected to the operating table 1. A fixing groove for placing the steel plate is formed between the two second positioning plates 4, and the second positioning plates 4 are collinear with their corresponding first positioning plates 2. In practical use, one steel plate is inserted into the fixing groove, and the other steel plate is inserted between the two first positioning plates 2, facilitating clamping and welding of the two steel plates.

[0024] The operating table 1 is equipped with a third positioning component for welding three steel plates. There are two sets of the third positioning components, and the first positioning component and the two sets of the third positioning components are arranged in a circular array.

[0025] The third positioning component includes a second sliding channel 11 and a fourth positioning plate 12. Two second sliding channels 11 and two fourth positioning plates 12 are provided. The second sliding channel 11 is located on the operating table 1, and the fourth positioning plate 12 is slidably disposed inside the corresponding second sliding channel 11. When the fourth positioning plate 12 extends upward from the corresponding second sliding channel 11, a fixing groove for placing steel plates is formed between the two fourth positioning plates 12. Two steel plates are inserted into the fixing grooves corresponding to the two sets of third positioning components, and the other steel plate is inserted between the two first positioning plates 2, facilitating clamping, fixing, and welding of the three steel plates.

[0026] The operating table 1 is equipped with a fourth positioning component for welding four steel plates. There are three sets of the fourth positioning components, and the first positioning component and the three sets of the fourth positioning components are arranged in a circular array.

[0027] The fourth positioning component includes a first sliding channel 6 and a third positioning plate 7. Two of each type of component are provided. The first sliding channel 6 is located on the operating table 1, and the third positioning plate 7 is slidably disposed within its corresponding first sliding channel 6. When the third positioning plate 7 extends upward from its corresponding first sliding channel 6, a fixing groove for placing steel plates is formed between the two third positioning plates 7. Three steel plates are inserted into the fixing grooves corresponding to the three sets of fourth positioning components, and the remaining steel plate is inserted between the two first positioning plates 2, facilitating the welding of the four steel plates.

[0028] This allows for the rapid fixing and welding of two, three, or four steel plates, and is especially suitable for welding the angle steel tower legs of power transmission towers.

[0029] By setting up structures such as the first positioning component, the second positioning component, and the third positioning component, it is easy to position different numbers of steel plates, and the operation is simple and convenient, improving the applicability of the special welding fixture for the angle steel tower feet of power transmission towers.

[0030] To control the movement of the third positioning plate 7 and the fourth positioning plate 12, a U-shaped frame 8 is fixedly connected to the bottom of the operating table 1. A second electric push rod 10 is fixedly connected to the U-shaped frame 8, and a first arc frame 9 is fixedly connected to the telescopic end of the second electric push rod 10. The bottom end of the third positioning plate 7 is fixedly connected to the first arc frame 9. When the telescopic end of the second electric push rod 10 is extended, the first arc frame 9 drives multiple third positioning plates 7 to move upward synchronously, and the third positioning plates 7 extend upward from the corresponding first sliding channel 6.

[0031] A first electric push rod 5 is fixedly connected to the U-shaped frame 8. A second arc frame 13 is fixedly connected to the telescopic end of the first electric push rod 5.
