During the use of box-type substation, daily maintenance is essential to ensure the normal operation of box-type substation.

[0003] The utility model patent with authorization announcement number CN209250032U discloses an auxiliary device for substation operation and maintenance, which comprises a base and a shell, the top of the base is fixedly installed with a shell, the bottom surface of the shell is fixedly installed with two groups of hydraulic telescopic rods, the output end of the hydraulic telescopic rod is fixedly installed with a push rod extending out of the shell through a mounting plate, the top of the push rod is fixedly installed with a support plate, and the top of the support plate is fixedly installed with a guardrail, an escalator is fixedly installed on the back of the shell, a box is fixedly installed on the other side of the shell, and two groups of winding rods are fixedly installed on the bottom surface of the box, two groups of placement plates are fixedly installed above the winding rods, a push-pull structure is fixedly installed on the base on the other side of the shell, a placement groove is provided inside the base, and a battery is fixedly installed inside the placement groove, a walking wheel is fixedly installed on the bottom of the base, and a manual telescopic rod is fixedly installed on the bottom of the base outside the walking wheel. Compared with traditional auxiliary devices, the auxiliary device for substation operation and maintenance is equipped with a hydraulic telescopic rod that enables the device to achieve the function of automatic lifting and retraction through a push rod. The staff can adjust the device according to the actual maintenance height, which improves the functionality of the device and reduces limitations. A support plate is provided through a guardrail to facilitate the staff to work at heights, avoid or reduce the situation of working on ladders, and improve the convenience and safety of the staff during operation. A box is provided to facilitate the staff to place the corresponding operating devices through a winding rod and a placement plate, which effectively achieves the effect of separating the devices from the wires and improves the working efficiency of the staff. The device is equipped with walking wheels to make it easier to use. The staff can move the device according to the actual situation, which improves the flexibility of the device, expands the scope of application, and facilitates popularization and use.

[0004] Although the placement plate provided on the auxiliary device for operation and maintenance of the substation is convenient for the staff to place the corresponding operating devices, the device still has the following problems in actual use: the placement plate of the device is fixedly installed and the installation height cannot be adjusted. During the maintenance process, when the staff are working at a height, not only are the tools placed on the placement plate difficult for the staff to use, but the parts disassembled by the staff during the maintenance process are also difficult to place on the placement plate. Therefore, the setting of the placement plate is difficult to meet the maintenance needs of the box-type substation. In view of this, we propose an auxiliary maintenance device for box-type substations. Utility Model Content
