[0028] In this embodiment: It should be noted that the base bracket 2 has been installed on the electric pole by bolts. In the process of installing the transformer body 1, the transformer body 1 and the base bracket 2 are hoisted by machinery, and the base bracket 2 is placed on the outer wall of the installed mounting bracket 3. The lower halves of the two corresponding docking rods 401 are passed through the inner cavity grooves of the mounting bracket 3. At the same time, the inner cavities of the upper and lower halves of the docking rods 401 half-wrap the outer wall of one end of the base bracket 2. The limiting rod 402 is passed through the docking rod 401 and the base bracket 2 from top to bottom in sequence until it contacts the outer wall of the docking rod 401. At this time, the limiting component of the limiting mechanism 5 on the rotating wheel 403 is released by giving the rotating wheel 403 a forward thrust, and then the rotating wheel 403 is rotated. The rotation will drive the transmission components of the transmission mechanism 4 to work, so that the two movable blocks 405 are close to each other under the transmission of the thread, and give an extrusion force to the support block 406 located at one end of the movable block 405, so that the support block 406 moves upward along the inner wall inclined groove of the movable groove 410. At this time, the lifting equipment gives a lifting force to the top of the transformer body 1, so that the transformer body 1 drives the base bracket 2 to move upward until the outer wall of the base bracket 2 abuts against the inner cavity of the docking rod 401, until the top of the support block 406 abuts against the bottom end of the base bracket 2, and at this time the top of the base bracket 2 also has no gap with the inner cavity of the docking rod 401. At this time, the limiting mechanism 5 is used to limit the rotation of the rotating wheel 403, so the lifting equipment of the transformer body 1 can be released, and the installation of the transformer body 1 can be completed at this time.

[0030] The limiting mechanism 5 further includes a second protrusion 502 which is fixedly connected to the outer wall of the first screw rod 404 and is located inside the rotating wheel 403 .

[0031] In this embodiment, the lower halves of the two corresponding docking rods 401 are passed through the inner cavity slots of the mounting bracket 3, and the connecting rod 407 at one end of one docking rod 401 will pass through the rotating sleeve 408 on the inner wall of the other docking rod 401. At the same time, the inner cavities of the upper and lower halves of the docking rod 401 will half-wrap the outer wall of one end of the base bracket 2. The limiting rod 402 is passed through the docking rod 401 and the base bracket 2 from top to bottom in sequence until it contacts the outer wall of the docking rod 401. At this time, by giving the rotating wheel 4 403, and the first screw rod 404 is driven by the second protrusion 502 to rotate. The screw rod 409 rotates, and the first screw rod 404 and the second screw rod 409 rotate to drive the two first screw rods 404 to approach each other along the thread, and give an extrusion force to the support block 406 at one end of the movable block 405, so that the support block 406 moves upward along the inner wall inclined groove of the movable groove 410 under the extrusion force. At this time, the lifting equipment gives a lifting force on the upper part of the transformer body 1, so that the transformer body 1 drives the base bracket 2 to move upward until the outer wall of the base bracket 2 abuts against the inner cavity of the docking rod 401, until the support block 4 The top of 06 is against the bottom of the base bracket 2, and at this time, there is no gap between the top of the base bracket 2 and the inner cavity of the docking rod 401. At this time, the rotating wheel 403 is pulled backward, and the movement of the rotating wheel 403 will drive the first protrusion 501 to move, so that the first protrusion 501 moves to the limiting groove inside the rotating wheel 403, and the rotating wheel 403 is limited, so that the first screw rod 404 will not rotate under external force, then the lifting equipment of the transformer body 1 can be released, and the installation of the transformer body 1 can be completed at this time.

The rotation of the rotating wheel 403 transmits the torque to the first screw rod 404 through the second protrusion 502, thereby driving the first screw rod 404 to rotate.

[0034] Please refer to Figure 2-6 The outer wall of the connecting rod 407 is a hexagonal structure, the inner cavity of the rotating sleeve 408 coincides with the outer wall of the connecting rod 407, the inner wall of the docking rod 401 is provided with a sliding groove matching the lateral movement trajectory of the movable block 405, the number of movable blocks 405 is set to two, the two movable blocks 405 are respectively installed on the outer walls of the two docking rods 401, the inner walls of the two movable blocks 405 are respectively provided with thread grooves matching the outer walls of the second screw rod 409 and the first screw rod 404, and the outer wall thread grooves of the second screw rod 409 and the first screw rod 404 are in opposite states, the outer wall of the support block 406 is an "L"-shaped structure, the cross-section of the movable groove 410 is an "L"-shaped structure, the inner wall of the movable groove 410 is provided with an oblique sliding groove matching the oblique movement trajectory of the support block 406, and the inner walls of the base bracket 2 and the docking rod 401 are provided with hole grooves matching the outer wall of the limit rod 402.

[0035] In this embodiment: the rotation of the first screw rod 404 will drive the connecting rod 407, the rotating sleeve 408, and the second screw rod 409 to rotate. The rotation of the first screw rod 404 and the second screw rod 409 will drive the two first screw rods 404 to approach each other along the thread, and give an extrusion force to the support block 406 located at one end of the movable block 405, so that the support block 406 moves upward along the inner wall inclined groove of the movable groove 410 under the extrusion force. At this time, the lifting equipment gives a lifting force on the top of the transformer body 1, so that the transformer body 1 drives the base bracket 2 to move upward until the outer wall of the base bracket 2 abuts against the inner cavity of the docking rod 401, until the top of the support block 406 abuts against the bottom end of the base bracket 2, and At this time, there is no gap between the top of the base bracket 2 and the inner cavity of the docking rod 401, so the lifting equipment of the transformer body 1 can be released, and the installation of the transformer body 1 can be completed. At this time, when the transformer body 1 is subjected to front and rear forces, the force will be blocked by the movable block 405 that resists the support block 406, and when it is subjected to left and right thrusts, the force will be blocked by the limit rod 402. Before taking out the limit rod 402, the transformer body 1 will always be connected to the outer wall of the installation bracket 3, and after manually taking out the limit rod 402, the transformer body 1 and the base bracket 2 can be quickly disassembled, thereby achieving the purpose of quickly installing and disassembling the transformer body 1 and further improving work efficiency.
