Understandably, the maintenance tool is a tent, and the tent is mainly composed of a shielding cloth and 4-6 columns according to the size of the equipment. The tool mainly uses an automatic lifting construction method, and the specific implementation manner relies on an intelligent lifting column. Among them, two motors are arranged on the hydraulic oil cylinder 4, the first motor 5 is arranged on the telescopic shaft 6 of the hydraulic oil cylinder 4, and the second motor 7 is arranged on the base 8 of the hydraulic oil cylinder 4; the output shaft of the first motor 5 is fixed to the inner top wall of the first telescopic section 1, and the first motor 5 can drive the first telescopic section 1 to rotate synchronously through the output shaft; the output shaft of the second motor 7 is fixedly connected with the movable rod 9, and the second motor 7 can drive the movable rod 9 to rotate through the output shaft. The second telescopic section 2 is sleeved outside the fixed section 3, and the first telescopic section 1 is sleeved outside the second telescopic section 2; and the hydraulic oil cylinder 4 is arranged in the first telescopic section 1.

[0030] In the embodiment, for the hydraulic oil cylinder 4, the two force bearing positions are the output shaft of the first motor 5 and the output shaft of the second motor 7. In order to protect the two motors, a force bearing support is arranged on the telescopic shaft 6 of the hydraulic oil cylinder 4, and the telescopic shaft 6 directly supports the first telescopic section 1 through the support, and the rotating mode is realized through the bearing; similarly, a support is arranged on the base 8 of the hydraulic oil cylinder 4 to directly bear the movable rod 9, and the rotating structure between the movable rod 9 and the output shaft of the second motor 7 is also realized through the bearing. This part about the structure of the bearing and the support is a common structure in the industry, and will not be described here.

[0031] One embodiment, the first slot is a straight line, from the second stretch 2 top to bottom, the first slot set at the top of a limit for fixing the force element 10. Understandably, the second stretch 2 of the outer edge of the 4 different function of the slot, two of which correspond with the force element 10, for A slot (first slot); the other two with the second motor 7 on the movable rod 9, for B slot (second slot).

Understandably, the fixed segment 3 of the outer edge of the 2 slot, also with the second motor 7 on the movable rod 9, for C slot (third slot).

[0033] One embodiment, the telescopic shaft 6 is vertically set in the hydraulic cylinder 4, when the telescopic shaft 6 moves up, the first stretch 1 is driven to move up synchronously, until the force element 10 moves to the top of the first slot; when the force element 10 moves to the top of the first slot, the force element 10 is turned into the limit of the first slot with the rotation of the first motor 5, the first stretch 1 and the second stretch 2 are fixed by mutual clamping. Understandably, when the driving column is driven to rise vertically, the hydraulic cylinder 4 is driven, the rising of the telescopic shaft 6 will drive the first stretch 1 to rise synchronously, at this time, the force element 10 on the first stretch 1 moves vertically along the A slot, the telescopic shaft 6 rises to the vertical turning point of the A slot, and then the first motor 5 is driven to rotate, driving the force element 10 to turn from the turning point of the A slot to the right side; at this time, the first stretch 1 is raised to the position, and the second stretch 2 and the fixed segment 3 are located at the bottom, when the force element 10 slides into the right side of the A slot, the first stretch 1 and the second stretch 2 are clamped, and the relative vertical movement between them is limited (because there are two slots above and below the right side of the A slot, the limitation here is not absolute), the second stretch 2 supports the first stretch 1, and the connection structure of the first stretch 1 and the telescopic shaft 6 of the hydraulic cylinder 4 is also realized, realizing the overall force support of the hydraulic cylinder 4.

[0034] One embodiment, the bottom of the telescopic shaft 6 is also provided with a base 8, the base 8 is sleeved on the outside of the movable rod 9; when the first telescopic section 1 and the second telescopic section 2 are mutually clamped and fixed, then move downward, the base 8 will drive the movable rod 9 to move upward in the second groove and the third groove, and the contraction is carried out. When the base 8 is completely contracted, the movable rod 9 moves to the top of the second groove and the third groove, and drives the second motor 7 to rotate the movable rod 9 through the output shaft, and the movable rod 9 and the fixed section 3 are clamped. It can be understood that the hydraulic cylinder 4 is driven again, and the hydraulic cylinder 4 is contracted, at this time the first telescopic section 1 and the second telescopic section 2 are stationary, when the contraction is carried out, the force receiving part 10 is located on the right side of the A groove, and the force receiving part 10 will gradually enter the lower part of the right side of the A groove, and the A groove realizes the axial rotation of the first telescopic section 1 and the hydraulic cylinder 4 as a whole; with the continuous contraction of the hydraulic cylinder 4, the base 8 will drive the movable rod 9 to move upward on the B groove and the C groove, and the B groove is mainly a avoiding groove; after the base 8 is completely contracted, the movable rod 9 moves to the top of the left side of the B groove and the top turning point of the left side of the C groove, and the hydraulic cylinder 4 is completed. After the completion of this part of the operation, the overall state is that the first telescopic section 1 is completed to rise, the fixed section 3 and the second telescopic section 2 are still located at the bottom and have not started to move.

[0035] Then drive the second motor 7, the output shaft drives the movable rod 9 to rotate, and the movable rod 9 is turned into the right side of the C groove, in this step, the B groove still realizes the avoiding effect; after the movable rod 9 enters the right side of the C groove, the movable rod 9 and the fixed section 3 are clamped, and the two are limited and cannot move relative to the vertical direction (because there is a lower groove on the right side of the C groove, the limitation here is also not absolute); the fixed section 3 supports the base 8 of the hydraulic cylinder 4, at this time the state is still unchanged, and the overall state is that the first telescopic section 1 is completed to rise, the fixed section 3 and the second telescopic section 2 are still located at the bottom and have not started to move.

[0036] One embodiment, when the movable rod 9 and the fixed section 3 are clamped, if the telescopic shaft 6 moves upward again, the first telescopic section 1 and the second telescopic section 2 are driven to move upward synchronously, until the telescopic shaft 6 is completed to stretch and the movable rod 9 is located at the bottom of the right side of the second groove. It can be understood that the hydraulic cylinder 4 is started again, due to the gravity, the base 8 of the hydraulic cylinder 4 moves downward first, so that the movable rod 9 moves into the lower part of the right side of the C groove, the C groove limits the axial rotation of the hydraulic cylinder 4 as a whole, and the C groove supports the hydraulic cylinder 4, even the first telescopic section 1 and the second telescopic section 2 as a whole through the movable rod 9; in order to optimize the rotation efficiency of the movable rod 9, a bearing is arranged at the end of the movable rod 9 (the part actually contacted and stressed with the C groove);

[0037] With the continuous extension of the hydraulic cylinder 4, the telescopic shaft 6 will drive the first telescopic section 1 and the second telescopic section 2 to move upward synchronously again through the first telescopic section 1 (the force receiving member 10 is clamped to connect the first telescopic section 1 and the second telescopic section 2), and the B groove realizes the avoidance effect on the movable rod 9 during the upward movement of the second telescopic section 2, and the movable rod 9 is located at the bottom on the right side of the B groove after the hydraulic cylinder 4 is fully extended, and at this time, the column completes the complete vertical upward movement.

[0038] In one embodiment, the bottom of the fixed section 3 is provided with an outwardly extending cross support 11 for force support of the fixed end. In the storage state, the bottom of the fixed section 3 is force supported by the outwardly expanding cross support 11.

[0039] In a specific embodiment, before the preparation of the equipment for maintenance, the laying of the shielding cloth is first completed, the shielding cloth is placed on the site, and then each column is placed at a position for connection and support of the shielding cloth. In order to avoid the rotation of the first telescopic section 1 during the extension of the column, a connecting piece for connecting the rope can be provided at the top of the first telescopic section 1, and the connecting piece is rotationally connected with the first telescopic section 1. After the position layout of the column and the layout of the shielding cloth are completed, the on-site operator can start all the columns synchronously through the integrated remote control connection mode, and synchronously raise and set up the shielding cloth to complete the setting up of the whole tent. It should be noted that in order to reduce labor costs, only one or two workers are often needed during maintenance, and the setting up and setting up method of the tent can be realized by the worker through step-by-step layout of the shielding cloth and the column and through remote control, which greatly improves the setting efficiency of the maintenance site.

[0040] In summary, the embodiment of the present application has the following beneficial effects:

[0041] The auxiliary maintenance tool for the transformer provided by the present application is used for providing a site for maintenance work by a worker, and only one worker is needed to prepare the site for maintenance work during the maintenance process, which greatly improves the setting efficiency of the maintenance site, has great convenience for the current maintenance work, adapts to various environmental conditions to improve the maintenance efficiency, and greatly reduces the labor cost.
