DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1: Reference Figure 1-2 , transformer installation and fixing components, including The crossbeam 1 is used to connect to the pole support beam 101. When in use, the crossbeam is fixed to the pole support beam 101 by fixing bolts. The crossbeam 1 itself can be fixed to the bottom of the transformer body 7 by fixing bolts or welding; The buffer adjustment shell 2 is arranged at the bottom of the transformer body 7; A buffer adjustment member 3, the lower end of which is inserted into the buffer adjustment housing 2; The cushioning airbag 5 is connected to the bottom of the cushioning adjustment member 3 and is connected to the bottom wall of the cushioning adjustment shell 2; During transportation, the cushioning airbag 5 provided between the cushioning adjustment shell 2 and the cushioning adjustment member 3 can provide cushioning.

[0020] Reference Figure 3-5 , multiple airbag adjustment top columns 6 are evenly distributed at the corners of the buffer adjustment part 3. The airbag adjustment top columns 6 can expand and contract, thereby adjusting the position of the buffer adjustment part 3 and the transformer body 7 relative to the buffer adjustment shell 2 The cushioning airbag 5 and the cushioning adjustment member 3 are both provided with an exhaust pipe 604. The cushioning adjustment member 3 is provided with an external exhaust pipe 603, a main pipe 602, and a branch pipe 601. The exhaust pipe 604 is in communication with the external exhaust pipe 603 and the main pipe 602. The exhaust pipe 604 is in communication with the main pipe 602. The main pipe 602 is in communication with the airbag airbag adjustment top column 6 through the branch pipe 601. The exhaust pipe 604, the external exhaust pipe 603, and the branch pipe 601 are all provided with electronic valves. The stabilizing component 4 is arranged at the bottom of the buffering and adjusting shell 2 and is used to stabilize the buffering and adjusting shell 2 on the pole support beam 101.

[0021] When installing the transformer, it is first dropped initially. At this time, the buffer adjustment shell 2 at the bottom of the transformer body 7 will first fall on the pole support beam 101, and the buffer adjustment shell 2 will be stabilized on the pole support beam 101 through the buffer adjustment shell 2 stabilizing component 4.

[0022] Then the transformer body 7 is slowly descending. At this time, through the buffering effect of the buffer airbag 5, the buffer adjustment part 3 and the transformer body 7 can both be slowly descended. At the same time, observe the position of the lower end crossbeam 1 of the transformer body 1 and the position of the screw hole on the pole support beam 101. If there is a position deviation, the buffer airbag 5 is squeezed by the weight of the transformer body 7 itself, and the gas in the buffer airbag 5 can be transported to the airbag adjustment top column 6. Because the airbag adjustment top column 6 is evenly distributed at the corners around the buffer adjustment part 3, by observing the screw hole position, the electronic valves on the branch pipes 601 on the multiple airbag adjustment columns 6 are controlled to open and close, so as to use the airbag adjustment column 6 to support the inner wall of the buffer adjustment shell 2, thereby realizing the position adjustment of the buffer adjustment part 3 relative to the buffer adjustment shell 2, so as to facilitate alignment. In specific implementation, the number of airbag adjustment columns 6 is preferably 8.

[0023] Example 2: Reference Figure 6-8 , transformer installation and fixing components, in this embodiment, the stabilizing component 4 is further optimized and limited. During the specific implementation, the weight of the transformer body 7 itself is used to press down the buffer airbag 5, and then the stabilizing component is driven to stabilize. Specifically, the stabilizing component 4 includes a screw sleeve 401 rotatably connected to the bottom of the buffer adjustment shell 2, and the two ends of the screw sleeve 401 are connected with symmetrical stabilizing top columns 402 through threads. The stabilizing top column 402 is used to support the inner side of the pole support beam 101, and the thread rotation direction of the stabilizing top column 402 is opposite to that of the connection end of the screw sleeve 401, and the stabilizing top column 402 is slidably connected to the bottom of the buffer adjustment shell 2.

[0024] During hoisting installation, the buffer adjustment shell 2 is first dropped and placed on the pole support beam 101, and the stabilizing top column 402 is driven to move in opposite directions at the same time by rotating the screw sleeve 401. The stabilizing top column 402 is located between the two pole support beams 101. As the stabilizing top column 402 moves, it is continuously supported closely by the pole support beam 101, thereby starting the stabilizing effect.

[0025] Reference Figure 6A gear sleeve 403 is fixedly sleeved on the screw sleeve 401, and a rack 404 meshing with the gear sleeve 403 is slidably connected to the buffer adjustment shell 2. A lifting chamber 405 connected to the buffer airbag 5 is provided on the buffer adjustment shell 2, and a lifting column 406 is slidably and sealedly connected in the lifting chamber 405. The lifting column 406 is fixedly connected to the rack 404, and an electronic valve is connected to the top of the lifting chamber 405. When the buffer airbag 5 is pressurized, the electronic valve on the lifting chamber 405 is opened to supply air to the lifting chamber 405, pushing the lifting column 406 and the rack 404 to move downward, thereby driving the screw sleeve 401 to rotate through the gear sleeve 403.

[0026] Reference Figure 8 A slider is fixedly connected to the stable top column 402, and a sliding groove matching the slider is provided at the bottom of the buffer adjustment shell 2 to ensure that the stable top column 402 slides forward stably.

[0027] Reference Figure 6 A reset spring 407 is connected between the inner wall of the lifting chamber 405 and the lifting column 406 , and the reset spring 407 facilitates the reset of the lifting column 406 .

[0028] Example 3: Reference Figures 9-11 , transformer installation and fixing components, in order to achieve the buffering effect of the buffering adjustment shell 2 and the buffering adjustment part 3 during transportation, and at the same time ensure that the buffering adjustment part 3 can be adjusted relative to the buffering adjustment 2, the buffering adjustment shell 2 is slidably connected with a sliding column 204, and the top of the sliding column 204 is detachably connected to the buffering adjustment part 3, and the buffering adjustment shell 2 and the top of the sliding column 204 are connected with a buffer spring 207. When transporting, the sliding column 204 slides up and down and the buffer spring 207 is used to achieve a buffering and shock-absorbing effect.

[0029] Reference Figure 11-12 The top end of the sliding column 204 is detachably connected to the buffer adjustment member 3, and the specific implementation is as follows: a sliding groove 202 is provided on the buffer adjustment shell 2, and a piston 203 is fixedly connected to the bottom end of the sliding column 204. The piston 203 is slidingly and sealingly connected in the sliding groove 202. A sliding sealing ring 205 is provided between the top of the sliding groove 202 and the sliding column 204. A driving chamber 206 is formed between the sliding sealing ring 205 and the piston 203. The driving chamber 206 is connected to the buffer airbag 5 through the delivery channel 201, and an electronic valve is provided on the delivery channel 201.

[0030] A locking chamber 211 is provided at the top of the sliding column 204, and a locking column 213 is slidably connected in the locking chamber 211. A locking groove 301 matching the locking column 213 is provided on the buffer adjustment member 3, and a sealing piston 210 is fixedly connected to the end of the locking column 213 away from the locking groove 301. A push spring 209 is connected between the sealing piston 210 and the inner wall of the locking chamber 211, and a sliding seal 212 is provided between the locking column 213 and the locking chamber 211. A delivery hole 208 is provided on the sliding column 208, and both ends of the delivery hole 208 are respectively connected to the locking chamber 211 and the driving chamber 206.

[0031] By opening the electronic valve on the delivery channel 201, air pressure enters the drive chamber 206 and is delivered to the locking chamber 211 through the delivery hole 208, thereby pushing the sealing piston 210 to drive the locking column 213 to move to the left, so that the locking column 213 disengages from the locking groove 301. As the air pressure in the drive chamber 206 continues to increase, the sliding column 204 will be driven downward by the piston 203, thereby realizing the disengagement of the sliding column 204 from the buffer adjustment member 3, and realizing the separation of the buffer adjustment member 3 from the buffer adjustment shell 2.

[0032] Example 4: Reference Figure 13 and 14 A transformer comprises a transformer body 7 and the transformer mounting and fixing assembly box of claim 1 , wherein the crossbeam 1 is fixedly connected to the bottom of the transformer body 7 , and the buffer adjustment member 3 is fixedly connected to the bottom of the transformer body 7 .
