[0002] Tower cranes, also known as tower cranes, are an indispensable lifting equipment on construction sites, used to lift raw materials such as steel bars, concrete, and steel pipes for construction. Existing tower crane climbing frames are mostly rectangular frame structures, and the assembly method is that a smaller rectangular frame is set inside a larger rectangular frame and the two are fixedly connected to form a relatively stable tower crane support body. In order to enhance the carrying capacity of the climbing frame, multiple inclined supports are generally welded to the rectangular frame structure, and most existing welding platforms can only weld the outer welds of the rectangular frame. For the internal inclined supports and the inner seam welding of the frame, it is necessary to weld separately or replace the tooling platform for welding, resulting in low assembly efficiency of the climbing frame.

The square tubes can be welded into a rectangular frame of a climbing frame through the first tooling platform 1. The four square tubes are placed on the positioning device 4 of the first tooling platform 1 for positioning. Then the rotation of the motor 6 drives the welding robot to weld.
