In one possible design, one side of the movable frame is fixedly connected with a ladder stand, one side of the fixed frame is fixedly connected with two handrail frames, and the two handrail frames are respectively positioned on two sides of the ladder stand.
In one possible design, a plurality of protection plates are fixedly connected between the bottoms of the fixing frames.
In one possible design, a plurality of reinforcing rods which are obliquely arranged are fixedly connected to the inside of the movable frame and are used for reinforcing the stability of the movable frame.
In one possible design, the bottom of the moving frame is fixedly connected with universal wheels.
When the metro vehicle maintenance device is used, when the position of the metro vehicle to be maintained changes, maintenance personnel can rotate the threaded rod by rotating the turntable at the top of the rotating rod, and the threaded rod is in threaded connection with the threaded block at the bottom of the sliding table, so that the sliding table is driven to move along the direction of the threaded rod by the rotation of the threaded rod, and the extension length of the sliding table is changed. When the sliding table stretches out to a proper position, the maintenance work of the metro vehicle can be carried out. The maintainer can get into inside the fixed frame through the cat ladder, utilizes the handrail frame to support and remove. The protection plate fixed to the bottom of the frame can provide additional security. After maintenance is completed, the sliding table can be retracted below the fixed table by reversely rotating the rotary table of the rotary rod, so that the platform can be conveniently moved and stored.
The maintainer can directly stand on the fixed station to adjust the extending length of the sliding table, so that the sliding table is convenient, and in the moving process of the sliding table, the two sliding blocks provide stable supporting force for the sliding table to prevent the sliding table from falling.
The beneficial effects are that:
According to the self-adaptive subway vehicle maintenance platform, the extension length of the sliding table can be conveniently adjusted through the design of the adjusting component so as to adapt to subway vehicles with different widths, and the maintenance flexibility and efficiency are improved;
According to the self-adaptive subway vehicle maintenance platform, the platform can be easily moved and positioned through the arrangement of the movable frame and the universal wheels, so that maintenance work on subway vehicles at different positions is facilitated.
