Description

Technical Field

[0001] This application belongs to the technical field of transformer disassembly and assembly, and particularly relates to a transformer transfer system. Background Art

[0002] Oil-immersed transformers are a type of transformer with relatively wide application, having a reasonable structure and excellent performance. To ensure the reliable operation of oil-immersed transformers, regular maintenance and servicing are required, such as performing core extraction inspections on oil-immersed transformers. For a core extraction inspection of an oil-immersed transformer, the oil-immersed transformer needs to be separated from the transformer room where it is located, and then the transformer moved outside the transformer room is sent to a specified and more suitable core extraction site for inspection.

[0003] Currently, when it is necessary to move a transformer relative to a transformer room, a mechanism for controlling the movement of the transformer is usually provided inside the transformer room. However, in this method, the separation of the transformer from the transformer room is prone to instability, presenting certain safety hazards. Also, due to the relatively small and limited space of the transformer room, it is inconvenient to cooperate with lifting equipment to transfer the transformer, and the overall versatility is not high. The transformers that can be transferred and applied are relatively limited, and the safety during the transfer of the transformer is not ideal enough. Summary of the Utility Model

[0004] This application aims to at least to a certain extent solve the technical problems that the transformers that can be transferred and applied are relatively limited and the safety during the transfer of the transformer is not ideal enough. For this purpose, this application provides a transformer transfer system.

[0005] An embodiment of this application provides a transformer transfer system for transferring a transformer located inside a transformer room. The transformer is supported on at least two spaced bases. The transformer transfer system includes:

[0006] A lifting mechanism, located between the bottom of the transformer room and the bottom of the transformer, and having a reciprocatingly liftable lifting end that abuts against the transformer;

[0007] At least two side-by-side steel rails, one end of which is used to be inserted between the corresponding base and the transformer, and the other end extends outside the transformer room;

[0008] A support platform for supporting the other end of the steel rail;

[0009] A telescoping mechanism having a telescoping end that reciprocates along the length direction of the steel rail, and the telescoping end is used to abut against the side of the transformer;

[0010] A lifting device, spaced from the transformer room and used to lift the transformer.

[0011] In some embodiments, the lifting mechanism is a jack, and a plurality of the jacks are arranged at intervals between the bottom of the transformer chamber and the bottom of the transformer, and one end of the jack that can reciprocally lift is configured as the lifting end.

[0012] In some embodiments, the length of the rail located outside the transformer chamber is 1.5 to 2 times the length of the rail located inside the transformer chamber.

[0013] In some embodiments, the rail includes a plurality of connection segments that are detachably connected in sequence along its length direction.

[0014] In some embodiments, the rail further includes:

[0015] A fishplate, with both ends respectively connected to adjacent two of the connection segments through fasteners.

[0016] In some embodiments, the transformer transfer system further includes:

[0017] At least two sliding pads, which are respectively slidably supported on the corresponding rails and are located between the corresponding rails and the transformer.

[0018] In some embodiments, the sliding pad includes a supporting portion and a limiting portion that are both plate-shaped, and there is an included angle between the supporting portion and the limiting portion. The supporting portion is slidably supported on the corresponding rail, and the limiting portion contacts the side surface of the rail.

[0019] In some embodiments, the transformer transfer system further includes a moving tool for assisting in moving the rail, and the moving tool includes:

[0020] A U-shaped portion.

[0021] Two coaxial bearings, which are oppositely and rotatably arranged in the U-shaped portion and are both located in the U-shaped groove corresponding to the U-shaped portion.

[0022] A handheld portion, which is fixedly connected to the bent portion of the U-shaped portion.

[0023] In some embodiments, the U-shaped portion is in the shape of a U-shaped rod, the handheld portion is in the shape of a tube, and the moving tool further includes a reinforcing rib connecting the handheld portion and the U-shaped portion.

[0024] In some embodiments, the transformer transfer system further includes:

[0025] At least two supporting members, which support the rail at intervals along the length direction of the rail.

[0026] Beneficial effects provided by one or more embodiments of the present application:

[0027] The lifting mechanism between the bottom of the transformer chamber and the bottom of the transformer in the transformer transfer system can reciprocally lift and has a lifting end that abuts against the transformer. When the lifting end ascends and descends, it can push the transformer upward, creating a gap between the bottom of the transformer and the base it supports, into which at least two parallel rails can be inserted. Then, the other end of each rail extends out of the transformer chamber and is supported on a support platform to ensure the height stability of the rails. Next, the lifting end of the lifting mechanism descends, causing the transformer to be supported on the rails. The rails can form a track for the transformer to move out of the transformer chamber. When combined with the telescopic end of the telescopic mechanism that can reciprocally extend and retract along the length of the rails, the telescopic end abuts against the side of the transformer, applying pressure to the transformer to enable it to move smoothly and completely out of the transformer chamber along the length of the rails. Finally, when combined with a lifting device, the transformer that has been moved out of the transformer chamber can be transferred to the destination. The above transformer transfer system can be applied to most transformers installed in transformer chambers with bases, without the need to modify the transformer or the transformer chamber. It has high overall versatility. Since the rails extend from the transformer chamber to the outside and are stably supported at both ends, the transformer can move stably out of the transformer chamber under the push of the telescopic mechanism. The possible sway and offset of the transformer are relatively small. The transformer can also cooperate with the lifting device after completely moving out of the transformer chamber, reducing the possible collisions of the transformer and improving the safety during the transformer transfer process. To a certain extent, it solves the technical problems that the applicable transformers are relatively limited and the safety during the transformer transfer is not ideal enough.

[0039] In the related art, in order to facilitate the transfer of the transformer, modifications are made in the transformer room. However, this method requires certain modifications to both the transformer and the transformer room, resulting in low versatility. Moreover, during the process of moving the transformer, the transformer lacks support when moving from the transformer room to the outside of the transformer room, and problems such as shaking and collision of the transformer are likely to occur, which affect the safety of the transformer transfer.

[0040] The present application will be described below with reference to the accompanying drawings:

[0041] Figure 1 shows the cooperation relationship diagram between the transformer room and the transformer in some embodiments or certain embodiments of the present application, Figure 2 shows the schematic diagram of the use state of a transformer transfer system in some embodiments or certain embodiments of the present application. Refer to Figure 1 and Figure 2 , the embodiments of the present application provide a transformer transfer system for transferring the transformer 100 located in the transformer room 300. The transformer 100 is supported on at least two spaced bases 200. The transformer transfer system includes:

[0042] A lifting mechanism 1 is located between the bottom of the transformer room 300 and the bottom of the transformer 100, and is provided with a reciprocatingly liftable lifting end 11 that abuts against the transformer 100.

[0043] At least two side-by-side steel rails 2, one end of which is used to be inserted between the corresponding base 200 and the transformer 100, and the other end extends outside the transformer room 300.

[0044] A support platform 3 is used to support the other end of the steel rail 2.

[0045] A telescopic mechanism 4 is provided with a telescopic end 41 that reciprocates telescopically along the length direction of the steel rail 2, and the telescopic end 41 is used to abut against the side of the transformer 100.

[0046] A lifting device (not shown in the figure) is spaced from the transformer room 300 and is used to lift the transformer 100.

[0047] The lifting mechanism 1 disposed between the bottom of the transformer chamber 300 and the bottom of the transformer 100 in the transformer transfer system has a lifting end 11 that can be lifted and lowered reciprocally and abuts against the transformer 100. The lifting and lowering of the lifting end 11 can push the transformer 100 to rise, so that a gap for inserting the rail 2 appears between the bottom of the transformer 100 and the base 200 supported by the transformer 100. Then, at least two parallel rails 2 are inserted between the transformer 100 and the base 200 in the transformer chamber 300, and the other end of each rail 2 extends out of the transformer chamber 300 and is supported on the support platform 3 to ensure the height stability of the rail 2. Then, the lifting end 11 of the lifting mechanism 1 is lowered to support the transformer 100 on the rail 2. The rail 2 can form a track for moving the transformer 100 to the outside of the transformer chamber 300. In conjunction with the telescopic end 41 of the telescopic mechanism 4 that can reciprocate and retract along the length direction of the rail 2, the telescopic end 41 abuts against the side of the transformer 100, and can apply pressure to the transformer 100 so that the transformer 100 can be smoothly and completely moved out of the transformer room 300 along the length direction of the rail 2. Finally, in conjunction with the lifting equipment, the transformer 100 that has been moved out of the transformer room 300 can be transferred to the destination. The above transformer transfer system can be applied to most transformers 100 arranged in a transformer chamber 300 with a base 200, and there is no need to modify the transformer 100 and the transformer chamber 300. The overall versatility is high, and the rail 2 extends from the transformer chamber 300 to the outside of the transformer chamber 300, and both ends can be stably supported. Then, the transformer 100 can be stably moved out of the transformer chamber 300 along the rail 2 under the push of the telescopic mechanism 4, and the shaking and displacement that may be generated by the transformer 100 are small. The transformer 100 can also cooperate with the lifting equipment after being completely moved out of the transformer chamber 300, which can also reduce the possible collision of the transformer 100 and improve the safety of the transformer 100 during the transfer process. To a certain extent, it solves the technical problem that the transformers 100 that can be transferred and applied are relatively limited and the safety when transferring the transformer 100 is not ideal.

[0048] It should be noted that the transformer 100 needs to be transferred and moved to the corresponding site mainly because there are certain requirements for the environment and site where the transformer 100 is located for the core-pulling inspection. The environment where the transformer room 300 is located may not meet the inspection requirements of the transformer 100, so it needs to be transferred to the corresponding site. Usually, a base 200 for supporting the transformer 100 is added in the transformer room 300 to facilitate the moving and installation of the transformer 100. The structure in this application does not need to modify the transformer 100 and the transformer room 300 either, so it can be applied to the transfer of most transformers 100 and has high versatility. Rails 2, etc. After the transformer 100 is overhauled, the lifting device can lower the transformer 100 to one end of the rail 2 located outside the transformer room 300, and then the transformer 100 can be dragged into the transformer room 300 for installation mechanically or manually. The reason for setting the telescopic mechanism 4 inside the transformer room 300 for the transformer 100 is mainly that the space inside the transformer room 300 is small, and adding the telescopic mechanism 4 can facilitate the pushing out of the transformer 100 from the transformer room 300. The bottom of the structure or equipment involved in this application is the part with the lowest height in the working state of the structure or equipment.

[0049] In some or certain embodiments, the lifting mechanism 1 is a jack. A plurality of jacks are arranged at intervals between the bottom of the transformer room 300 and the bottom of the transformer 100, and the end of the jack that can reciprocally lift is configured as the lifting end 11.

[0050] The lifting mechanism 1 being a jack is small in volume and can support the relatively heavy transformer 100. A plurality of jacks can stably support the transformer 100 and improve the lifting efficiency of the transformer 100, so as to improve the transfer efficiency of the transformer 100.

[0051] For easy understanding, here is provided Figures 3 to 5 , Figures 3 to 5 a schematic diagram showing the lifting process of the transformer in some or certain embodiments of this application. Figure 3 In [diagram], the transformer 100 is lifted by a plurality of jacks located between the two bases 200, and a gap appears between the transformer 100 and the base 200. Figure 4 In [diagram], the corresponding rails 2 are inserted between the base 200 and the transformer 100. Figure 5 In [diagram], the jacks are depressurized, and the transformer 100 is supported on the rails 2. Figure 3 The view directions in [diagram] and Figure 4 are the front view and the rear view of the transformer 100 respectively. Figure 5 The jack structure is omitted in [diagram].

[0052] In some embodiments, the lifting mechanism 1 can also be set as, for example, a ball screw or a telescopic cylinder, etc. A support plate or the like can also be added to the telescopic end of the telescopic cylinder or the jack, so that the three jacks or telescopic cylinders can also realize the lifting of the transformer 100.

[0053] In some embodiments, the lifting mechanism 1 can be arranged between at least two bases 200 in the transformer chamber 300, which can make full use of the relatively small space in the transformer chamber 300 and reduce interference, and is applicable to the transformer 100 in a relatively small space.

[0054] In some embodiments, the telescopic mechanism 4 can also be a jack. The jack has a small volume and can be horizontally placed into the transformer chamber 300. The two ends of the horizontally placed jack can be respectively abutted against the transformer 100 and the side wall of the transformer chamber 300, and the transformer 100 can be pushed to move along the length direction of the rail 2 by telescoping. After the transformer 100 is moved out of the transformer chamber 300, the jack is also convenient to take out from the transformer chamber 300.

[0055] In some embodiments, the length of the rail 2 outside the transformer chamber 300 is 1.5 to 2 times the length of the rail 2 inside the transformer chamber 300.

[0056] When the lengths of the rail 2 inside and outside the transformer chamber 300 are respectively within the above ranges, the rail 2 is relatively stable, and the rail 2 outside the transformer chamber 300 can also realize the stable support of the transformer 100.

[0057] In some embodiments, the rail 2 includes a plurality of connection segments 21 that are detachably connected in sequence along its own length direction.

[0058] The rail 2 includes a plurality of connection segments 21 that are detachably connected in sequence along its own length direction, which is convenient for the movement and installation of the rail 2. Especially for the transformer 100 with a relatively large specification, the corresponding rail 2 also has certain size and strength requirements. The plurality of connection segments 21 are detachably connected in sequence, which is convenient for the formation and placement of the rail 2.

[0059] In some embodiments, the rail 2 further includes:

[0060] Fishplate 22, the two ends of which are respectively connected to adjacent two connection segments 21 through fasteners. It is convenient to realize the connection between the connection segments 21, and the manufacturing cost is relatively low. The fasteners can be structures such as bolts and nuts.

[0061] In some embodiments, according to the specifications of the transformer 100 and the transformer chamber 300, the rail 2 can also be set as an integral structure. It can also realize the movement and transfer of the transformer 100.

[0062] In some embodiments, the transformer transfer system further includes:

[0063] At least two sliding pads 5 are respectively slidably supported on corresponding rails 2 and are located between the corresponding rails 2 and the transformer 100.

[0064] When the transformer 100 is pushed to move, the sliding pads 5 can move relative to the rails 2 together with the transformer 100, converting the static friction between the transformer 100 and the rails 2 into sliding friction, which can reduce the moving resistance of the transformer 100 to a certain extent and improve the transfer efficiency of the transformer 100.

[0065] Figure 6 The figure shows a schematic structural diagram of a sliding pad in some embodiments or certain embodiments of the present application. Refer to Figure 6 , in some or certain embodiments, the sliding pad 5 includes a supporting part 51 and a limiting part 52 that are both plate-shaped. There is an included angle between the supporting part 51 and the limiting part 52. The supporting part 51 is slidably supported on the corresponding rail 2, and the limiting part 52 contacts the side surface of the rail 2. It can achieve sliding and there is a certain mutual limiting effect between the limiting part 52 and the side surface of the rail 2, facilitating the movement of the transformer 100 while ensuring the stable movement of the transformer 100.

[0066] In some or certain embodiments, the sliding pad 5 can also be set as a U-shaped plate buckled on the rail 2, etc., and the width of the U-shaped plate can be greater than the width of the rail 2. It can also improve the moving efficiency of the transformer 100.

[0067] Figure 7 The figure shows a schematic structural diagram of a moving tool in some embodiments or certain embodiments of the present application. Refer to Figure 7 , in some or certain embodiments, the transformer transfer system further includes a moving tool 6 for assisting in moving the rail 2. The moving tool 6 includes:

[0068] A U-shaped part 61.

[0069] Two coaxial bearings 62 are oppositely and rotatably arranged in the U-shaped part 61 and are both located in the U-shaped groove corresponding to the U-shaped part 61.

[0070] A handheld part 63 is fixedly connected to the bent part of the U-shaped part 61.

[0071] The moving tool 6 can assist in the movement of the rail 2. Especially for rails 2 of larger specifications that include multiple connecting segments 21, each connecting segment 21 can be moved in cooperation with the moving tool 6. When using the moving tool 6, the U-shaped part 61 of the moving tool 6 can be sleeved on one end of the connecting segment 21. Through the rotatable bearing 62 in the U-shaped groove corresponding to the U-shaped part 61, the moving tool 6 can move relative to the connecting segment 21 to the middle in the length direction of the connecting segment 21. Then, the two opposite and coaxial bearings 62 of the moving tool 6 can become the lever axis of the connecting segment 21, controlling both ends of the connecting segment 21. It is possible to use the bearing 62 as the lever node to move the connecting end of the rail 2, improving the transfer efficiency of the transformer 100.

[0072] In some embodiments, the U-shaped part 61 is in the shape of a U-shaped rod, the hand-held part 63 is in the shape of a tube, and the moving tool 6 further includes a reinforcing rib 64 connecting the hand-held part 63 and the U-shaped part 61. The moving tool 6 has a relatively high strength, is relatively light, and is easy to move.

[0073] In some embodiments, the support platform 3 can be a cubic platform or a frustum of a cone, etc. All can achieve the support of the rail 2.

[0074] It should be noted that the support platform 3 is used to support the other end of the rail 2 so that the rail 2 can be in or close to the horizontal plane of the environment during use.

[0075] In some embodiments, the transformer transfer system further includes:

[0076] At least two support members 7 that support the rail 2 at intervals along the length direction of the rail 2. This improves the stability of the movement of the transformer 100 on the rail 2. These support members 7 can also be located between the support platform 3 and the transformer chamber 300, providing better stability.

[0077] In some embodiments, the support member 7 can be in the shape of a block or a cube, etc., and the width of the support member 7 is greater than the width of the rail 2. The support member 7 can also play a certain supporting role for the transformer 100 when the transformer 100 is moving.

[0078] In some embodiments, the lifting device (not shown in the figure) can be a crane or an overhead crane, etc. The boom of the crane can be set according to the position of the transformer chamber 300, and the moving track of the overhead crane can be located obliquely above the transformer chamber 300.

[0079] In the description of this specification, the descriptions referring to terms such as "one embodiment", "some embodiments", "examples", "specific examples", or "some examples" etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application.

Moreover, the specific features, structures, materials, or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine the different embodiments or examples described in this specification.

When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.
