A first rotating shaft 104 is provided inside the friction damping spring device 103. The first rotating shaft 104 is used to connect the first connecting rods 102 on different sides, so that when the first connecting rod 102 on one side rotates, the first connecting rod 102 on the other side is driven to rotate. The number of the first rotating shafts 104 is two, and the first rotating shafts 104 are fixedly connected to the first connecting rod 102. Both ends of the first rotating shaft 104 are fixedly connected to the first connecting rod 102, and the end of the first rotating shaft 104 away from the first connecting rod 102 is rotatably connected to the gradual buffer device 105; The two first connecting rods 102 on the same side are driven to rotate by the gear synchronous transmission device 101, and then the two rotating first connecting rods 102 on the same side drive the two first connecting rods 102 on the other side to rotate through the first rotating rod, and then the rotating first connecting rods 102 drive the gradual buffer device 105 to perform lifting and lowering movements.

[0024] The gradual buffering device 105 includes a first hollow rectangular shell 1051, the material of the first hollow rectangular shell 1051 is a supporting material with relatively high hardness, the first hollow rectangular shell 1051 is fixedly connected to the inside of the second hollow rectangular shell 1052, the second hollow rectangular shell 1052 is a relatively soft vibration-damping material, the second hollow rectangular shell 1052 is fixedly connected to the inside of the third hollow rectangular shell 1053, the hollow positions of the first hollow rectangular shell 1051, the second hollow rectangular shell 1052, and the third hollow rectangular shell 1053 are consistent, the material of the third hollow rectangular shell 1053 is a supporting material with relatively high hardness, the first hollow rectangular shell 1051, the second hollow rectangular shell 1052, and the third hollow rectangular shell 1053 are fixedly connected to the inside of the first hollow rectangular shell 1051.

The first oil-immersed transformer 1054 is fixedly connected to the interior of the third hollow rectangular shell 1053. The second hollow rectangular shell 1052 is used to reduce the vibration of the first oil-immersed transformer 1054 caused by the movement of the equipment.

The bottom of the smooth lifting device 1 is fixedly connected to the smooth moving device 3; When the gradual buffering device 105 moves, due to the effect of inertia, the first oil-immersed transformer 1054 generates an impact force on the third hollow rectangular shell 1053, and then the third hollow rectangular shell 1053 transmits the impact force to the second hollow rectangular shell 1052, and then the second hollow rectangular shell 1052 transmits the impact force to the first hollow rectangular shell 1051.

When the moving direction of the gradual buffering device 105 is consistent with the axial direction of the friction damping spring device 103, the friction damping spring device 103 will further weaken the impact force generated by the inertia of the first oil-immersed transformer 1054.

[0025] Example 2, based on Example 1, please refer to Figure 5-9The present invention provides a technical solution: the smooth moving device 3 includes a rectangular base 301, the rectangular base 301 is rotatably connected to the first connecting rod 102, the rectangular base 301 is fixedly connected to the gear synchronous transmission device 101, the bottom of the rectangular base 301 is fixedly connected to an elastic boosting friction device 302, the number of the elastic boosting friction devices 302 is four, and they are evenly distributed at the bottom of the rectangular base 301, the elastic boosting friction devices 302 are movably connected to the rubber roller vibration damping device 303 inside, the number of the rubber roller vibration damping devices 303 is four, the four rubber roller vibration damping devices 303 are located inside the four elastic boosting friction devices 302, a rectangular through groove 304 is provided on the surface of the connecting rod of the rubber roller vibration damping device 303, the bottom of the rectangular base 301 is rotatably connected to a rotation redirecting device 305, the rotation redirecting device 305 is slidably connected to the rectangular through groove 304, and the width of the connecting rod of the rotation redirecting device 305 is consistent with the width of the rectangular through groove 304. The rotation redirecting device 305 is used to drive the rubber roller vibration damping device 303 to rotate and change the moving direction of the roller of the rubber roller vibration damping device 303 when the rubber roller vibration damping device 303 is not under pressure from the rectangular base 301. A uniform and slow telescopic device 306 is fixedly connected to the bottom of the rectangular base 301. The uniform and slow telescopic device 306 is used to cooperate with the rubber roller vibration damping device 303 for steering. At the same time, the uniform and slow telescopic device 306 can also be used to adjust the flatness of the oil-immersed transformer that is easy to adjust through the bubble level 2 in conjunction with the uniform and slow telescopic device 306 in different positions. There are four uniform and slow telescopic devices 306, which are evenly distributed between the two rubber roller vibration damping devices 303. The uniform and slow telescopic device 306 is used to gradually release the elastic force of the elastic boosting friction device 302 through uniform and slow telescopic when the elastic boosting friction device 302 needs to release the elastic force, so as to avoid the elastic force of the elastic boosting friction device 302 being released instantly and causing excessive vibration.

[0026] The elastic pressure-boosting friction device 302 includes a first cylindrical shell 3021, which is fixedly connected to the rectangular base 301. An arc-shaped pressure plate 3022 is rotatably connected inside the first cylindrical shell 3021. The rough surface of the arc-shaped pressure plate 3022 is used to increase the friction force on the connecting rod of the rubber roller vibration damping device 303 when the rubber roller vibration damping device 303 is subjected to pressure from the top. There are four arc-shaped pressure plates 3022 and four first compression springs 3023. The side of the arc-shaped pressure plate 3022 away from the first cylindrical shell 3021 is a rough surface. The four arc-shaped pressure plates 3022 are used to increase the friction force on the connecting rod of the rubber roller vibration damping device 303 when the rubber roller vibration damping device 303 is subjected to pressure from the top. The arc pressure plate 3022 and the first compression spring 3023 are evenly distributed on the inner wall of the first cylindrical shell 3021. The first compression spring 3023 is fixedly connected to the inside of the first cylindrical shell 3021. The end of the first compression spring 3023 away from the inner wall of the first cylindrical shell 3021 is fixedly connected to the arc pressure plate 3022. The first compression spring 3023 is used to apply a rebound force to the rubber roller vibration damping device 303 when the rubber roller vibration damping device 303 is not under pressure from the top, so that the connecting rod of the rubber roller vibration damping device 303 is away from the elastic boosting friction device 302.

[0027] The working principle of the second embodiment is as follows: when the oil-immersed transformer that is easy to adjust needs to be moved on a plane, the pressure of the oil-immersed transformer that is easy to adjust is borne by the rubber roller vibration damping device 303. Under the action of this pressure, the rubber roller vibration damping device 303 approaches the top of the elastic pressure-boosting friction device 302. During this process, the connecting rod of the rubber roller vibration damping device 303 applies pressure to the arc-shaped pressure plate 3022, and then the arc-shaped pressure plate 3022 transmits this pressure to the first compression spring 3023, and then the first compression spring 3023 contracts. When the connecting rod of the rubber roller vibration damping device 303 reaches the limit close to the elastic pressure-boosting friction device 302, the roller of the rubber roller vibration damping device 303 starts to rotate, driving the oil-immersed transformer that is easy to adjust to move; When the direction of the oil-immersed transformer that is easy to adjust needs to be adjusted, the uniform and slow telescopic device 306 is slowly extended to slowly lift up the oil-immersed transformer that is easy to adjust. During this process, the rubber roller vibration damping device 303 loses the pressure from the oil-immersed transformer that is easy to adjust. Under the action of the rebound force of the first compression spring 3023 and gravity, the rubber roller vibration damping device 303 begins to slowly leave the elastic boosting friction device 302. Since this process is relatively slow, the secondary vibration caused by the rebound force of the first compression spring 3023 is avoided. After the uniform and slow telescopic device 306 is slowly extended to a sufficient length, the rubber roller vibration damping device 303 is driven to rotate by the rotating redirecting device 305 to change the moving direction of the oil-immersed transformer that is easy to adjust.

[0028] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
