DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0021] Embodiment one In order to achieve the purpose of automatic supplement of auxiliary support when the transformer is lifted, and to provide certain redundant support for the transformer during the supplement of auxiliary support, please refer to Figures 1-4 The present embodiment provides a transformer hydraulic jacking and translation device, which comprises a translation track 1, a horizontal pushing assembly 2 and a jacking assembly 3. The horizontal pushing assembly 2 pushes the transformer to move along the translation track 1, and at least one set of jacking assembly 3 pushes the transformer to rise above the translation track 1. The jacking assembly 3 comprises a bottom plate 31, a first hydraulic cylinder 32, a belt conveyor 33, a lifting assembly 34 and a cushion block 35. The bottom plate 31 is arranged between the translation tracks 1, the first hydraulic cylinder 32 is fixed on the top of the bottom plate 31, the lifting assembly 34 is installed on the top of the bottom plate 31, the belt conveyor 33 conveys the cushion block 35 to the lifting assembly 34, and the lifting assembly 34 comprises a longitudinal plate 341, an elastic telescopic rod 342, a motor 343 and a side plate 344. The longitudinal plate 341 is arranged on the bottom plate 31, the elastic telescopic rod 342 is rotationally connected with the longitudinal plate 341, the motor 343 is fixed on the longitudinal plate 341, the motor 343 drives the elastic telescopic rod 342 to rotate, and the side plate 344 is rotationally connected with the bottom of the elastic telescopic rod 342.

[0022] The first hydraulic cylinder 32 is connected with the pump station and the synchronous control system. In use, the first hydraulic cylinder 32 is arranged below the transformer, the pump station is started, the synchronous control system controls all the first hydraulic cylinders 32 to synchronously jack up, the transformer is stably lifted off the foundation, the first pad 35 below the transformer is placed between the two side plates 344 by the worker, and the two side plates 344 are limited, so that the two side plates 344 are prevented from being pushed close by the elastic telescopic rods 342. The height of the pad 35 is set as H. When the transformer is jacked up by H, the motor 343 drives the elastic telescopic rods 342 to rotate upwards. The elastic telescopic rods 342 press the pad 35 from both sides through the side plates 344, and drive the pad 35 to be lifted. Until the pad 35 below the transformer is pushed up and abuts against the bottom of the transformer, the belt conveyor 33 conveys the pad 35 above it to between the two side plates 344, until the pad 35 on the belt conveyor 33 is conveyed below the pad 35 pressed and lifted by the two side plates 344, the process of automatically supplementing the pad 35 below the transformer is completed, and finally the motor 343 drives the side plates 344 to rotate downwards through the elastic telescopic rods 342, until the side plates 344 rotate to the pad 35 at the bottom, so that the side plates 344 can start to lift the pad 35 from the pad 35 at the bottom below the transformer each time. The above process is repeated, and the pad 35 at the bottom is automatically supplemented each time the transformer is jacked up by H, so that the total height of the pads 35 below the transformer is increased.

[0023] Since the motor 343 drives the elastic telescopic rods 342 to support the transformer from below, when the transformer accidentally falls, the pad 35 below the transformer needs to be pushed. In this process, the elastic telescopic rods 342 are pushed to contract, and then drive the rotating shaft of the motor 343 to rotate. The motor 343 is provided with an electromagnetic brake. When power is off, the brake automatically locks the rotor. The transformer needs to overcome the elastic force of the elastic telescopic rods 342 and the resistance of the electromagnetic brake of the motor 343 to fall, so as to assist in supporting the transformer. The auxiliary support structure below the transformer can be automatically supplemented after the transformer is jacked up, so that the worker does not need to continuously supplement the auxiliary support below the transformer, the safety hazard of the worker is reduced, and the transformer can be continuously provided with redundant support during the auxiliary support process. When the transformer accidentally falls, the protection of the transformer is realized, the sinking and inclination of the transformer when the transformer accidentally falls are reduced, and the risk of falling of the transformer during movement is reduced.

[0024] In order to push the transformer to move along the track to the specified position after the transformer is jacked up on the track, referring to Figure 1 , the horizontal pushing assembly 2 comprises a clamping block 21, a second hydraulic cylinder 22 and a sliding plate 23. The clamping block 21 is fixed on the translation track 1. The second hydraulic cylinder 22 is rotationally connected with the clamping block 21. The sliding plate 23 is fixed on the movable end of the second hydraulic cylinder 22. The sliding plate 23 is slidably connected with the translation track 1.

[0025] In use, the jacking assembly 3 jacks up the transformer above the sliding plate 23, then lays the translation rail 1 under the transformer, and fixes the clamping block 21 on the translation rail 1, then the jacking assembly 3 drives the transformer to descend until the transformer is supported by the sliding plate 23, at this time the first hydraulic cylinder 32 is continuously retracted, and the jacking assembly 3 is removed from under the transformer, then the second hydraulic cylinder 22 pushes the sliding plate 23 and the transformer to move along the translation rail 1 until the transformer is moved to the designated position, and finally the jacking assembly 3 is used to lift the transformer to the designated height, completing the jacking and translation process of the transformer.

[0026] Embodiment two In order to adjust the position of the cushion block 35 under the transformer, make the cushion block 35 neatly arranged, thereby reducing the possibility of the cushion block 35 staggered stacking causing easy loosening and falling, referring to Figures 1-5 On the basis of embodiment one, the top of the side plate 344 is provided with a guide plate 4, the top of the guide plate 4 is arc-shaped, the two side plates 344 and the guide plate 4 are oppositely arranged, the top of the side plate 344 is provided with a sliding groove 5, the guide plate 4 extends into the sliding groove 5, and the bottom of the guide plate 4 is fixedly connected with the spring 6 between the sliding groove 5.

[0027] In use, the side plate 344 is at the bottommost cushion block 35 under the transformer, when the motor 343 drives the side plate 344 to move upward, because the two side plates 344 are limited by the cushion block 35 in the middle, the side plate 344 can only be raised along the longitudinal direction, in this process, the elastic expansion rod 342 is deformed to move away from the side plate 344, the elastic force generated by the deformation of the elastic expansion rod 342 extrudes the cushion block 35, and a clamping force is formed on the cushion block 35, driving the bottommost cushion block 35 to rise, thereby driving the whole stack of cushion blocks 35 to rise.

[0028] When the cushion block 35 is raised against the bottom of the transformer, the cushion block 35 cannot continue to be pushed up, new cushion blocks 35 are supplemented under the cushion blocks 35 clamped by the side plate 344, so that the bottom of the cushion blocks 35 clamped by the side plate 344 cannot be lowered, at this time the motor 343 drives the side plate 344 to continue to rise, the side plate 344 will slide and rise relative to the cushion block 35, the cushion blocks 35 that are not neatly stacked will slide along the arc-shaped top of the guide plate 4, and be extruded by the guide plate 4 to align with other cushion blocks 35, finally the guide plate 4 extrudes the bottom of the transformer, slides into the inside of the side plate 344 after being blocked by the transformer, extrudes and retracts the spring 6, and finally the motor 343 is reversed to drive the side plate 344 to descend to the bottommost cushion block 35, completing a period of supplementing the cushion block 35, and repeating the above process, constantly supplementing the cushion blocks 35 under the transformer when the transformer is raised, which can calibrate the position of the cushion block 35 under the transformer, make the cushion block 35 neatly arranged, and reduce the possibility of the cushion block 35 staggered stacking causing easy loosening and falling.

[0029] Embodiment three In order to make the transformer fall more smoothly when the transformer falls accidentally, thereby reducing the possibility of the transformer falling off the support structure, with reference to Figures 1-6 On the basis of embodiment one, the elastic telescopic rod 342 includes an outer tube 3421, an inner rod 3422, a limiting plate 3423 and an elastic plate 3424, the outer tube 3421 is rotationally connected with the longitudinal plate 341, the inner rod 3422 penetrates through the outer tube 3421, the limiting plate 3423 is arranged in the outer tube 3421 and is fixed with the inner rod 3422, and the elastic plate 3424 is fixed between the limiting plate 3423 and the outer tube 3421.

[0030] In use, the motor 343 drives the side plate 344 to move upward, since the two side plates 344 are limited by the cushion block 35 in the middle, the side plate 344 can only be raised along the longitudinal direction, and in this process, the inner rod 3422 is pushed to move away from the side plate 344, the inner rod 3422 drives the limiting plate 3423 to move and extrude and bend the elastic plate 3424, the elastic force generated by the deformation of the elastic telescopic rod 342 extrudes the cushion block 35, when the elastic plate 3424 is extruded and bent, on the one hand, the elastic force is generated due to the deformation, and on the other hand, the side surface of the elastic plate 3424 slides along the inner wall of the outer tube 3421, and the friction force between the elastic plate 3424 and the inner wall of the outer tube 3421 needs to be overcome, when the transformer falls accidentally, not only the elastic force of the elastic plate 3424 and the resistance of the electromagnetic brake of the motor 343 need to be overcome, but also the friction force needs to be overcome by pushing the elastic plate 3424 to slide along the inner wall of the outer tube 3421, the mode and intensity of the redundant support provided for the transformer are increased, and stronger auxiliary support can be provided when the transformer falls accidentally.

[0031] Embodiment four In order to make the jacking and translation device adapt to transformers of different sizes and still be able to complete the jacking and translation of the transformer when the size of the transformer is small, with reference to Figures 1-6 On the basis of embodiment one, the bottom plate 31 is rotationally connected with a rotating disc 7 at the top, the lifting assembly 34 is installed at the top of the rotating disc 7, the rotating disc 7 is fixedly connected with a protrusion 8 at the top, the bottom of the cushion block 35 is provided with a limiting groove 9, the limiting groove 9 includes a horn mouth area and a rectangular area with the same width as the protrusion 8, the bottom of the belt conveyor 33 is fixedly connected with a bent plate 10, and the bent plate 10 is fixed with the bottom plate 31 through bolts.

[0032] When the size of the transformer to be moved is large, the two rails of the translation track 1 are expanded, the translation track 1 supports the transformer from a wider range, the belt conveyor 33 in the lifting assembly 3 is fixed on the side of the base plate 31, and the distance between the two rails is sufficient to accommodate the width of the lifting assembly 3. When the size of the transformer to be moved is small, the two rails of the translation track 1 are shortened, the belt conveyor 33 is fixed on the base plate 31 close to the lifting assembly 34 at this time, and then the rotating disc 7 is rotated to make the lifting assembly 34 face the belt conveyor 33. When the belt conveyor 33 transports the pad 35 to the rotating disc 7, the protrusion 8 limits the movement position of the pad 35, so that the pad 35 is aligned with the middle of the lifting assembly 34, and the movement direction of the pad 35 can be calibrated when the pad 35 is transported. It can meet the lifting and translation requirements of transformers of different sizes.
