[0040] When in use, the power equipment fault inspection and repair device is moved to the vicinity of the power equipment that needs to be inspected, and is moved by the push handle 9 and the moving wheel 2. The height of the lifting platform 5 is adjusted as needed, which is achieved by operating the switch of the electric push rod 43. When the electric push rod 43 is working, its output end will push the top plate 42 to move up and down relative to the bottom plate 41.

The guardrail 63 is slid to the required height and fixed by the mounting mechanism 7. According to the on-site conditions, the height of the stabilizing mechanism 3 is adjusted by operating the switch of the servo motor 306 to ensure the stability of the device during use. Maintenance personnel can climb onto the lifting platform 5 through the ladder 8 and perform power equipment fault inspection and repair work under the protection of the guardrail mechanism 6. After the inspection and repair is completed, the lifting assembly 4, the guardrail mechanism 6 and the stabilizing mechanism 3 are operated in reverse order to restore the device to its initial state and move it to the next inspection point or storage position.

[0041] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0042] In summary, the power equipment fault inspection and repair device, by setting a stabilizing mechanism 3, is located on the inner side of the mounting seat 1, and the stabilizing mechanism 3 is adjusted to contact with the ground, so as to increase the stability of the device during operation. When the staff performs inspection and repair work on the lifting platform 5, the position of the stabilizing plate 304 is adjusted by controlling the servo motor 306. The servo motor 306 drives the bidirectional threaded rod 308 to rotate, so that the two threaded blocks 309 move relative to or oppositely on the bidirectional threaded rod 308. The movement of the threaded block 309 drives the lifting plate 302 to move up and down through the round rod 311 and the rectangular block 305, and then adjusts the height of the U-shaped frame 303 and the stabilizing plate 304, so that the stabilizing plate 304 contacts with the ground, thereby increasing the stability of the device during use and achieving the purpose of higher stability. By setting a guardrail mechanism 6 and a mounting mechanism 7, the guardrail mechanism 6 is fixed to the mounting mechanism 7 after the height is adjusted. The design of the rotating rod 75 and the rotating drum 76 allows the user to adjust the position of the two movable plates 72 at the same time by turning the handle 78, so that the block 73 can quickly fix or release the vertical plate 64. After the contact block 73 limits the vertical plate 64, the height of the guardrail 63 can be adjusted as needed. After the adjustment is completed, the handle 78 is released, and the contraction force of the fixing spring 74 causes the movable plate 72 and the block 73 to reset, and the vertical plate 64 can be fixed again, thereby achieving the purpose of adjustable guardrail height. The problem that the height of the guardrail is fixed and cannot be adjusted, while the height of the maintenance personnel is different, the guardrail with a fixed height cannot effectively protect the maintenance personnel with a taller height, resulting in poor protection of the guardrail, and no corresponding stabilizing structure is set. If a position offset occurs during the maintenance process, the overall stability of the device will be poor, which will bring inconvenience to the maintenance work.
