Second, the guide wheel, support car and support plate need to be installed on the tank body in advance, and need to be removed after the arc-extinguishing chamber assembly is completed, which is complicated and time-consuming, resulting in low assembly efficiency. In addition, the support car and support plate need to be installed on the inner surface of the tank body, which may scratch the surface during assembly. Therefore, it is very important to design a tank tooling that does not affect the efficiency of product assembly and ensures the safety and reliability of product operation. Utility model content

The support height of the guide rail support frame 32 is adjusted through the height adjusting member, so that the guide rail 4 can enter the tank body 1 at different heights, and the use is more convenient.

[0026] Specifically, the height adjusting member is a vertically extending adjusting screw 33, the upper end of the adjusting screw 33 is connected with the guide rail support frame 32 through double nuts, and the lower end of the adjusting screw 33 is connected with the moving frame 31 through double nuts. The height can be adjusted by rotating the position of the double nuts, and the adjustment is convenient.

[0027] Specifically, the guide rail support frame 32 is provided with a support roller 34 supported at the bottom of the guide rail 4. The guide rail moves through the rolling of the support roller, which is more labor-saving and convenient. The top of the moving frame 31 of the embodiment is provided with two groups of guide rail support frames 32, and the two groups of guide rail support frames 32 are arranged along the length direction of the guide rail 4, thereby improving the stability during the movement of the guide rail.
