Description

Technical Field

[0001] This utility model belongs to the technical field of box-type transformers, and specifically relates to a support device for box-type transformers. Background Technology

[0002] A prefabricated transformer (also known as a box-type substation or box-type transformer) is a complete set of power distribution equipment that integrates high-voltage switchgear, transformer, and low-voltage power distribution devices. Its overall structure is enclosed in a sealed metal or composite material enclosure. Due to its excellent sealing and environmental adaptability, prefabricated transformers are widely used in urban power grids, industrial parks, residential communities, and power supply systems in complex outdoor environments.

[0003] In practical applications, when a box-type transformer requires internal debugging during production and assembly, or needs to be returned to the factory for repair due to a malfunction during operation, it is often necessary to hoist it as a whole and place it on a supporting structure. This allows for inspection, welding, wiring, or component replacement of the bottom structure, thus providing ample operating space. Currently, common support methods for box-type transformers include simple brackets, stacked sleepers, or temporary steel platforms. However, these traditional support structures have several technical drawbacks: firstly, they have poor structural stability, are prone to tilting or even overturning, posing serious safety hazards; secondly, they are inconvenient to assemble and disassemble during transportation or on-site operations, affecting work efficiency. Utility Model Content

[0004] In view of the various shortcomings of the existing technology, a box-type transformer support device is proposed to solve the technical problems of poor stability and inconvenient disassembly and assembly in the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A box-type transformer support device includes a support beam for supporting the box-type transformer. Several legs are provided below the support beam and are detachably connected to it. Each leg includes a base and a column. The column is arranged vertically, with its bottom connected to the base and its top provided with a mounting seat. The support beam is mounted above the mounting seat, and a positioning element is provided between the two.

[0006] The technical solution is further configured such that the base is flat and a support column is provided between the base and the column.

[0007] The technical solution is further configured such that, along the circumference of the column, there are several supporting columns.

[0008] The technical solution is further configured such that the mounting base is provided with a mounting cavity for placing the support beam, and the top of the support beam extends to the outside of the mounting cavity.

[0009] The technical solution is further configured such that a limiting groove is provided on the bottom surface of the mounting cavity.

[0010] The technical solution is further configured such that the positioning member is disposed inside the mounting cavity, and a connecting member is slidably connected to the side wall of the mounting cavity. One end of the connecting member is connected to the positioning member, and the other end of the connecting member extends to the outside of the mounting cavity and is locked by a locking member.

[0011] The technical solution is further configured such that the support beam includes a top plate and a support plate, the top plate is located above the mounting base, the support plate is located in the mounting cavity, and the positioning member abuts against the support plate. The technical solution is further configured such that several support beams are arranged in parallel and spaced apart, and several legs are provided below each support beam for detachable connection.

[0012] The beneficial effects of this utility model are: 1. The box-type transformer is supported by setting up feet and support beams.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0017] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0018] According to an embodiment of this utility model, a box-type transformer support device is provided. Please refer to [link / reference]. Figures 1 to 4 The system includes a support beam 100 for supporting a box-type transformer. Several legs 200 are detachably connected to the support beam 100 below it. Each leg 200 includes a base 202 and a column 201. The column 201 is arranged vertically, with its bottom connected to the base 202 and its top provided with a mounting seat 300. The support beam 100 is mounted on the mounting seat 300, and a positioning element 400 is provided between the two.

[0019] Furthermore, the support beam 100 can be arranged along the length or width of the box-type transformer. Simultaneously, the support beams 100 can be stacked along the same direction to accommodate the support requirements of box-type transformers of different specifications.

[0020] Understandably, the box-type transformer is supported by support legs 200 and support beams 100. Several support legs 200 are provided along the length of the support beams 100, employing multi-point support to improve the stability of both the support beams 100 and the box-type transformer. Furthermore, the support legs 200 and support beams 100 are detachably connected, facilitating assembly and disassembly. The support range can also be adjusted by increasing the number of support beams 100 and support legs 200, offering high flexibility and versatility.

[0021] In one embodiment of the box-type transformer support device, please refer to... Figures 1 to 4 The base 202 is flat, and a support column 203 is provided between the base 202 and the column 201.

[0022] Furthermore, adjustable feet can be provided on the base 202 to adapt to the flatness of the ground.

[0023] Furthermore, the support column 203 connects the upright column 201 and the base 202, forming a triangular or near-triangular support structure, which significantly improves the overall resistance to lateral forces and overturning, and can effectively suppress structural swaying or tilting, especially when subjected to eccentric loads or external disturbances.

[0024] Specifically, the support column 203 includes two support plates, which intersect at a right angle or an acute angle. In other words, the cross-section of the support column 203 is V-shaped or L-shaped, which can more evenly decompose and transfer the vertical and lateral loads borne by the column 201 to different areas of the base 202, avoiding stress concentration in local areas.

[0025] Understandably, the flat base 202 has a large ground contact area with the ground, which can effectively disperse the concentrated load of the box-type transformer or support device, reduce the ground pressure per unit area, and prevent settlement or overturning caused by excessive local pressure.

[0026] In one embodiment of the box-type transformer support device, please refer to... Figures 1 to 4 Along the circumference of the column 201, there are several support columns 203.

[0027] Specifically, the column 201 is located at the center of the base 202, and four support columns 203 are arranged around the circumference of the column 201 to support the column 201 from four directions. The angle between the central axis of the support column 203 and the central axis of the column 201 is 45°-60°. Within this angle range, the moment arm formed by the support column 203 is moderate and can effectively resist the overturning moment generated by the load on the top of the column 201.

[0028] Understandably, multiple support columns 203 are evenly distributed around the circumference of the upright column 201, forming a ring-shaped support structure, which effectively constrains the upright column 201 in all directions. The multiple support columns 203 provide multi-directional diagonal tension or bracing reinforcement to the upright column 201, greatly improving its resistance to bending and torsion. Simultaneously, the multiple support columns 203 evenly distribute the load borne by the upright column 201 to different areas of the base 202, preventing deformation, cracking, or fatigue damage to the base 202 due to excessive localized stress.

[0029] In one embodiment of the box-type transformer support device, please refer to... Figures 1 to 4 The mounting base 300 is provided with a mounting cavity for placing the support beam 100, and the top of the support beam 100 extends to the outside of the mounting cavity.

[0030] In use, the legs 200 (including mounting bases 300) can be pre-arranged in a straight line on the ground at the required spacing. The support beam 100, acting as a crossbeam, is directly inserted into the mounting cavity of each mounting base 300, forming a "plug-in assembly" structure. No on-site welding or complex alignment is required, making operation simple and significantly reducing installation and disassembly time. The mounting cavity guides and limits the support beam 100, ensuring its straightness among the multiple legs 200 and preventing slippage, torsion, or detachment during load-bearing, thus ensuring stable load transfer. The top of the support beam 100 extends to the outside of the mounting cavity, meaning the top of the support beam 100 directly abuts against the box-type transformer, achieving rigid contact load-bearing and efficiently transferring the weight of the box-type transformer along the path of support beam → mounting base → legs → ground.

[0031] Furthermore, the bottom surface of the mounting cavity is provided with a limiting groove 301 to limit the support beam 100, wherein the support beam 100 may be made of channel steel.

[0032] In one embodiment of the box-type transformer support device, please refer to... Figures 1 to 4 The positioning member 400 is disposed inside the mounting cavity, and a connecting member 500 is slidably connected to the side wall of the mounting cavity. One end of the connecting member 500 is connected to the positioning member 400, and the other end of the connecting member 500 extends to the outside of the mounting cavity and is locked by the locking member 600.

[0033] Furthermore, the positioning element 400 is located on the side of the support beam 100, and a through hole is formed on the side wall of the mounting cavity. The connecting element 500 is threadedly engaged with the locking element 600. Two locking elements 600 are provided, located on opposite sides of the side wall of the mounting cavity, forming a clamping mechanism that applies force simultaneously from both sides. By rotating the locking element 600, the axial displacement of the connecting element 500 can be precisely adjusted, thereby controlling the clamping force of the positioning element 400 on the support beam 100.

[0034] In one embodiment of the box-type transformer support device, please refer to... Figures 1 to 5 The support beam 100 includes a top plate 101 and a support plate 102. The top plate 101 is located above the mounting base 300, and the support plate 102 is located in the mounting cavity. The positioning member 400 abuts against the support plate 102.

[0035] Understandably, the top plate 101 directly contacts the bottom of the box-type transformer, bearing the vertical load and acting as a load-bearing platform. The support plate 102 is embedded inside the mounting cavity, serving as the "embedded section" or "connecting section" of the support beam 100, forming a structural connection with the mounting base 300, and receiving lateral constraints from the positioning element 400. Simultaneously, the insertion of the support plate 102 into the mounting cavity, combined with the limiting groove 301, provides guidance and centering, assisting the support beam 100 in quickly and accurately positioning itself onto multiple mounting bases 300.

[0036] In one embodiment of the box-type transformer support device, please refer to... Figure 1 The support beams 100 are arranged in parallel and spaced apart, and each support beam 100 is provided with several legs 200 that are detachably connected to it.

[0037] Understandably, several parallel and spaced support beams 100 form an array-like load-bearing frame on the ground, making large-area contact with the bottom of the box-type transformer to achieve multi-point, uniform load-bearing, effectively distributing weight and avoiding localized stress concentration. Furthermore, the spacing can be flexibly adjusted according to the bottom structure, center of gravity distribution, or support point location of the box-type transformer to accommodate different models and sizes of box-type transformers.
