When it is necessary to install the transformer body 2, first, the cross arm 1 is placed between two wire poles, then the pressing shaft 307 is pressed downward, the downward movement of the pressing shaft 307 drives the mounting plate 303 to slide, the sliding of the mounting plate 303 makes the first spring 306 contract, and meanwhile the mounting plate 303 drives the limiting blocks 304 to disengage from the limiting grooves 305, after the pressing shaft 307 moves downward to a certain position, the pressing shaft 307 is rotated by means of the threaded sleeve 308, so that the threaded sleeve 308 is threadedly engaged with the threaded column 309, at this time the mounting plate 303 cannot slide upward under the action of the first spring 306, at this time the adjusting rods 301 can slide relative to the cross arm 1, the sliding of the adjusting rods 301 drives the anti-dropping blocks 302 to slide, the arrangement of the anti-dropping blocks 302 can prevent the adjusting rods 301 from sliding off the cross arm 1, so as to avoid the danger of accidental falling during installation or use, during the sliding process, the length of the adjusting rods 301 sliding out of the cross arm 1 can be flexibly controlled according to the actual distance between the two wire poles, and the sliding distances of the two adjusting rods 301 sliding out of the cross arm 1 are kept consistent by observing the scale bar 310 on the adjusting rod 301, so as to ensure the accuracy and balance of installation, after the adjustment is completed, the threaded sleeve 308 is disengaged from the threaded column 309, and the mounting plate 303 is reset under the elastic force of the first spring 306.The limiting block 304 is re-engaged with the limiting groove 305, thereby completing the adjustment of the adjusting rod 301.

When it is necessary to overhaul the sleeve and other components above the transformer body 2, the hydraulic rod 507 can be started. When the extension end of the hydraulic rod 507 is elongated, the connecting rod 506 is driven to move upward. The movement of the connecting rod 506 causes the abutting rod 707 to no longer be subjected to the abutting force. At this time, the fixed rod 701 slides under the action of the second spring 710. The fixed rod 701 slides in cooperation with the guide rod 709. The arrangement of the guide rod 709 makes the sliding of the fixed rod 701 more stable and smooth. The fixed rod 701 drives the connecting block 702 to move. The movement of the connecting block 702 drives the driving shaft 703 to roll in the driving groove 705, and then drives the sliding rod 706 to move upward. One side of the sliding rod 706 drives the other side of the sliding rod 706 to move upward synchronously through the fixed plate 708. At the same time, the fixed rod 701 is no longer engaged with the rotating rod 502. The rack 505 is engaged with the gear 504. At this time, the hydraulic rod 507 continues to elongate, driving the rack 505 to move upward. The rack 505 drives the gear 504 and the fixed shaft 503 to rotate, so that the fixed shaft 503 drives the rainproof top plate 9 to rotate. When it is rotated by ninety degrees, the rainproof top plate 9 no longer shields the sleeve and other components, providing an open operating space for overhauling the sleeve and other components, improving the efficiency of the overhaul, and reducing the overhaul time. When the overhaul is completed, the hydraulic rod 507 is completely retracted, so that the four rotating rods 502 are kept in a vertical state with the mounting frame 501. At this time, the connecting rod 506 of the extension end of the hydraulic rod 507 abuts against the abutting rod 707 to move downward. The abutting rod 707 cooperates with the driving block 704 and other components to make the fixed rod 701 and the rotating rod 502 re-engage, completing the fixation of the rotating rod 502. The fixed rod 701 fixes the rotating rod 502, avoiding the abrasion of the meshing part of the gear 504 caused by vibration during the operation of the transformer body 2, causing the rainproof top plate 9 to loosen and affecting its protective performance. The four rotating rods 502 are fixed by the fixed rod 701, effectively dispersing the influence of vibration, avoiding the abrasion of the gear 504, and ensuring that the rainproof top plate 9 always remains stable.
