[0025] As an optional implementation, the moving part 1 may include a plurality of track wheels 11 and a brake assembly connectable to the track wheels 11; the plurality of track wheels 11 are respectively movably connected to two adjacent tracks.

[0026] like Figure 2 As shown, the track wheel 11 can be configured with an inwardly protruding structure, so that when the track vehicle is placed on the track, the outer part of the track wheel 11 is above the track, and the inner protruding part can adhere to the inner sidewalls of two adjacent tracks. This ensures that the track vehicle is stable on the track and will not deviate from the track or tip over to one side, improving the stability of the track vehicle. A braking assembly is also provided. When the track vehicle needs to operate at a certain position, the braking assembly can stably stop the track vehicle at the corresponding position, preventing it from moving due to track incline or forces that may exist in various directions during operation. This ensures construction safety and further improves the stability and practicality of the track vehicle.

[0027] The number of track wheels 11 can be four, with two on each side of the track. In addition, to improve the stability of the track vehicle, or depending on the weight, size, and structure of the track vehicle, six or eight wheels can also be provided. This application does not limit this.

[0031] As shown in Figure 2 , when the track vehicle needs to be braked, the worker can move the movable rod 15, so that the movable rod 15 moves along the moving hole 16 and drives the pin 14 to extend out of the moving cavity and be inserted into the first pin hole and the second pin hole 111, so that the track wheel 11 is fixed to the support frame 12, thereby realizing the effect of stabilizing the track vehicle at the current position. The track vehicle can be stably stopped at the corresponding position, and will not move due to the slope of the track or the force in each direction that may exist during the work on the track vehicle, thereby ensuring the safety of the construction and further improving the stability and practicality of the track vehicle.

[0032] As an optional implementation, the load-bearing part 2 comprises a load-bearing frame 22 connected with the moving part 1, and an extension frame 23 is arranged on one side of the load-bearing frame 22; a plurality of operation positions 21 are arranged on the extension frame 23 and the load-bearing frame 22, respectively.
