Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a technical solution, please refer to Figure 1 and Figure 2 A mobile operation device for substation operation and maintenance includes: a base 1, a scissor lift 2, a top plate 3, a tool box 4 and a box door 5, the scissor lift 2 is assembled between the base 1 and the top plate 3, the tool box 4 is assembled inside the top plate 3, and the box door 5 is assembled on both sides of the tool box 4 through hinges, and the bottom of the box door 5 is equipped with a self-locking mechanism 6.

[0024] The base 1 can support the scissor lift 2, and the scissor lift 2 can drive the top plate 3 to climb. The scissor lift 2 is a common scissor lift device in the prior art. The top plate 3 can support the tool box 4, and the tool box 4 can be filled with maintenance tools. The box door 5 can close the tool box 4.

[0025] The four corners of the bottom of the base 1 are evenly distributed with movable casters 11, and the outside of the movable casters 11 is equipped with a driving power supply. The movable casters 11 are common electric movable devices in the prior art, which include movable wheels, motors, and controllers. The motor drives the movable wheels through the control of the controller to drive the base 1 to move.

[0026] The front of the top plate 3 is connected to a fence door 31 through a hinge, and the front of the fence door 31 is connected to a handle. The fence door 31 can facilitate the staff to enter the interior of the top plate 3 and be driven to climb by the scissor lift 2. A bearing is connected at the junction of the vertical shaft 61 and the toolbox 4, and a rubber sleeve is installed on the outside of the vertical shaft 61. The bearing can support the vertical shaft 61, and the rubber sleeve can protect the vertical shaft 61.

[0027] The top plate 3 includes a transverse plate, the top of which is provided with a square groove matched with the seat bearing 68, and the top of the transverse plate is equipped with a fence. The transverse plate is convenient for workers to climb up, and the fence improves the overall safety of the top plate 3.

[0028] See also Figure 3 and Figure 4 The self-locking mechanism 6 includes a vertical shaft 61, a worm wheel 62 is connected to the bottom of the vertical shaft 61, a worm 63 is meshedly connected to the outside of the worm wheel 62, a gear 64 is connected to the front of the worm 63, a rack 65 is meshedly connected to the outside of the gear 64, a slotted block 66 is connected to the outside of the rack 65, and the slotted block 66 is connected to the top plate 3, and a spring 67 is connected between the slotted block 66 and the rack 65.

[0029] The vertical shaft 61 can be driven by the worm gear 62, and the rack 65 can drive the worm 63 to drive the worm gear 62 to move by moving up and down through the gear 64. At the same time, the worm gear 62 and the worm gear 63 have a self-locking feature. The slotted block 66 cooperates with the spring 67 to guide the rack 65 and return it after driving the movement.

[0030] The front side of the gear 64 and the back side of the worm 63 are both connected with a seat bearing 68 , and the seat bearing 68 is connected to the top plate 3 , and the seat bearing 68 can support the worm 63 and the gear 64 .

[0031] When the substation needs to be repaired in this scheme, the maintenance tools are placed inside the tool box 4, and the mobile casters 11 are started to drive the base 1 to move to the outside of the substation. The staff stands on the top of the top plate 3 and drives the top plate 3, the tool box 4 and the box door 5 to rise through the scissor lift 2 to perform maintenance and repair operations on the substation. At the same time, the top plate 3 drives the rack 65 to move in different directions when moving. At this time, the rack 65 is no longer in contact with the top of the base 1, and then returns to its position, thereby driving the gear 64 to rotate, and then driving the worm wheel 62 to rotate through the worm 63, and finally driving the box door 5 to rotate through the vertical shaft 61, contacting the closure of the tool box 4, and locking the tool box 4 at the same time. The staff takes out the maintenance tools from the inside of the tool box 4 to complete the maintenance of the substation. After the maintenance is completed, the tools are put back and the scissor lift 2 is started to return. At this time, the self-locking mechanism 6 is again resisted and returned by the base 1, thereby driving the box door 5 to return to its position and close the tool box 4;

[0032] When climbing up to inspect the inside of the substation, the position of the box door 5 is automatically driven and locked to prevent the box door 5 from swinging due to the flow of gas at high altitudes, which may cause safety hazards to the staff. At the same time, the tool box 4 is automatically unlocked by the box door 5 through the self-locking mechanism 6 when it is in use, and is automatically driven to close the box door 5 through the self-locking mechanism 6 when it is not in use, thereby greatly improving the overall use effect of the tool box 4 and preventing the loss of maintenance tools due to the staff forgetting to lock the tool box 4 after using the tools.
