[0002] In dangerous environments such as coal mines, due to the presence of explosive factors such as flammable gases (such as methane) and combustible dust, traditional electrical equipment is prone to fire or explosion, posing a threat to the safety of miners and equipment. Therefore, the design of mine electrical equipment must take into account the risk of explosion and take corresponding explosion-proof measures. Mine flameproof substations came into being. In order to ensure the normal transmission of electricity and maintain the normal operation of the substation, some equipment in the substation needs to be regularly inspected and maintained. The existing mobile maintenance platform of the mine flameproof substation can basically meet the daily use needs, but there are still some shortcomings that need to be improved.

[0003] Most of the mobile maintenance platforms widely used on the market adopt mobile pallets, so that workers can board the pallets for maintenance operations. However, due to the high height of the pallet, it is easy to shake during use, which may cause workers to fall easily, posing certain safety hazards. For this reason, we propose a mobile maintenance platform for mine flameproof substations to solve the above problems. Summary of the invention

[0024] In other embodiments, the width of the through hole 8 on the rotating plate 6 is the same as the width of the positioning column 7;

[0025] With this design, when the rotating plate 6 drives the through hole 8 to be sleeved on the outside of the positioning column 7, the enclosure 4 can be prevented from rotating.

[0026] In other embodiments, the outer wall of the movable block 11 is fully fitted with the inner wall of the movable inner cavity 10, and the movable block 11 is slidably connected with the movable inner cavity 10;

[0027] Through this design, when the movable block 11 slides along the inside of the movable inner cavity 10, it can effectively prevent the movable block 11 from shaking during the movement, thereby improving the stability of the device when in use.
