[0004] Currently, the inductors used in vehicle power supply systems are very large in size and weight. During maintenance, they need to be removed from the vehicle and then transported to the repair workshop for maintenance. Since the inductors are installed inside the frame of the subway auxiliary inverter, the hydraulic lifting transport vehicle cannot fully penetrate into the frame, resulting in a certain distance between the inductor and the hydraulic lifting transport vehicle. It is not safe to remove the inductor and place it directly on the hydraulic lifting transport vehicle. Simple brackets are often used for transition.

[0005] Therefore, there is an urgent need to design suitable tooling to achieve a safe transition from inductor disassembly to the hydraulic lifting transport vehicle. Utility Model Content

[0006] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide an auxiliary tooling for the transfer of inductors in rail transit vehicles.

[0007] According to the present invention, an auxiliary tooling for transferring inductors in rail transit vehicles includes: an upper square frame, a lower square frame, anti-tipping support feet, a reinforcing tube, and a wear-resistant pad. The upper square frame and the lower square frame have the same shape and structure. The upper square frame and the lower square frame are both arranged in a horizontal direction and are fastened together by multiple connecting plates. A plurality of elongated mounting holes for connecting inductors and the wear-resistant pad are provided on the top surface of a set of opposite sides of the upper square frame.

[0008] A plurality of anti-tipping support feet are symmetrically arranged on a set of opposite sides of the lower square frame.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This utility model connects the upper and lower square frames into a whole by multiple connecting plates, which is simple in structure and easy to manufacture, and increases the overall sturdiness of the transfer auxiliary tooling; by setting multiple anti-tipping support feet, the stability of the transfer auxiliary tooling can be improved while minimizing material usage, reducing costs, and facilitating widespread application; by setting multiple wear-resistant pads at intervals on the top surface of the upper square frame, in addition to wear resistance, it can also avoid rigid contact between the inductor and the bearing platform, playing a certain buffering role and reducing accidental damage to the inductor.

[0029] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0030] like Figure 1-3As shown, an auxiliary tooling for transferring inductors in rail transit vehicles according to this utility model includes: an upper square frame 1, a lower square frame 2, anti-tipping support feet 3, reinforcing tubes 5, and wear-resistant pads 6. The upper square frame 1 and the lower square frame 2 have the same shape and structure. Both the upper square frame 1 and the lower square frame 2 are arranged in a horizontal direction and are fastened together by multiple connecting plates. A plurality of elongated mounting holes 4 for connecting inductors and wear-resistant pads 6 are provided on the top surface of a set of opposite sides of the upper square frame 1. Each elongated mounting hole 4 is used to lock with the inductor. A plurality of anti-tipping support feet 3 are symmetrically arranged on a set of opposite sides of the lower square frame 2. The anti-tipping support feet 3 include a horizontal plate and a vertical plate. The vertical plate is arranged perpendicular to the lower square frame 2 and extends upward from the lower square frame 2 to the lower surface of the upper square frame 1. The inner side of the vertical plate is attached to and fastened to the upper square frame 1, the connecting plates, and the lower square frame 2. A reinforcing tube 5 is provided between the horizontal plate and the anti-tipping support feet 3.

[0031] This application connects the upper square frame 1 and the lower square frame 2 into a single unit using multiple connecting plates, increasing the overall robustness of the transfer auxiliary tooling. Simultaneously, the use of multiple anti-tipping support feet 3 enhances the stability of the transfer auxiliary tooling while minimizing material usage, reducing costs, and facilitating widespread application. Furthermore, considering the actual installation environment of the inductor, the area enclosed by the upper square frame 1 can be smaller than the area enclosed by the lower square frame 2. Combined with the connecting plates forming a boss structure (smaller at the top and larger at the bottom), this allows for deeper insertion into the inductor's installation location, bringing it closer to the inductor, reducing the falling distance during inductor removal, and improving safety.

[0032] The anti-tipping support foot 3 includes a right-angle bent plate. The horizontal plate is a right-angled sector shape, and the vertical plate is securely connected to one right-angled side of the sector. The other right-angled side of the sector is securely connected to the reinforcing tube 5, with the curved edge facing outwards. The sector-shaped horizontal plate increases the contact area between the transfer auxiliary tooling and the hydraulic lifting vehicle, improving overall stability and reducing the risk of tipping. The vertical plate reconnects the connecting plate, upper square frame 1, and lower square frame 2, providing reinforcement and enhancing stability.

[0033] The inner edge of the vertical plate has stepped latches, which follow the same trend as the lower square frame 2, the upper square frame 1, and the corresponding connecting plates, and are connected together by welding. The outer edge of the vertical plate has an overall L-shaped structure, and the corners are all curved. The top of the vertical plate is firmly connected to the lower surface of the upper square frame 1, and does not exceed the outer edge of the upper square frame 1, and its bottom end transitions to the horizontal plane with a curve.

[0034] The reinforcing tube 5 is flat, and its upper surface is firmly connected to the lower surface of the lower square frame 2. Both ends of the side of the reinforcing tube 5 are firmly connected to two horizontal plates. The ends of the lower square frame 2, the reinforcing tube 5, and the horizontal plates are aligned, meaning the fan-shaped arc edge of the horizontal plate extends from the end of the lower square frame 2. Considering the limited thickness of the lower square frame 2, a flat reinforcing tube 5 can be installed on the bottom surface of the side where the anti-tipping support foot 3 is located. The slot on the vertical plate of the right-angle bent plate can extend to the bottom surface of the reinforcing tube 5, and its horizontal plate can be connected to the bottom side of the reinforcing tube 5 to improve welding strength.

[0035] In this application, the upper square frame 1 and the lower square frame 2 are arranged parallel and spaced apart. They have the same structure, and their inner edges are connected together by connecting plates. Each pair of adjacent connecting plates is connected to each other. That is, the inner edges of the upper square frame 1 and the lower square frame 2 are fastened together by four vertical connecting plates, and the upper and lower ends of the connecting plates are connected to the upper square frame 1 and the lower square frame 2 by arc-shaped surfaces. Any two adjacent plates are fastened together. Anti-tipping support feet 3 are provided at the four corners of the lower square frame 2. That is, two anti-tipping support feet 3 are symmetrically provided on each side of the lower square frame 2, and the vertical plates are located inside the horizontal plates. Multiple elongated mounting holes 4 are provided on the top surface of one pair of parallel frame edges of the upper square frame 1. Each elongated mounting hole 4 is used to lock with an inductor. Preferably, the anti-tipping support feet 3, elongated mounting holes 4, and wear-resistant pads 6 are all provided on the long sides of the upper square frame 1 and the lower square frame 2. Multiple wear-resistant pads 6 are evenly spaced on the top surface of the upper square frame 1.

[0036] The area enclosed by the upper square frame 1 is smaller than the area enclosed by the lower square frame 2, forming an overall boss structure. This parallel upper and lower boss structure allows for sufficient depth into the electrical equipment box to contact the transfer equipment. The use of anti-tipping support feet 3 enhances overall stability and reduces the risk of tipping. This solves the safety and technical problems associated with existing simple tooling that relies entirely on the experience and eyesight of maintenance personnel to achieve proper connection with inductors, requiring frequent and repeated movements and long operation times.

[0037] Two anti-tipping support feet 3 are set together and are respectively set on two opposite sides of the lower square frame 2. The vertical surfaces of the two anti-tipping support feet 3 on the same side are opposite each other, and the arc-shaped edge of the horizontal plane extends from the end of the side. In this way, the edges of the exposed anti-tipping support feet 3 are all arc-shaped transitions, which can effectively reduce the risk of accidental damage. Setting anti-tipping support feet on the same side can improve the portability of the transfer auxiliary tooling and facilitate transportation.

[0038] The top surface of the upper square frame 1 is also provided with multiple wear-resistant pads 6 at intervals. Holes are also made on the wear-resistant pads 6 corresponding to the positions of the elongated mounting holes 4. In addition to being wear-resistant, these pads can also prevent rigid contact between the inductor and the support platform, thus playing a certain buffering role and reducing the risk of accidental damage to the inductor.

[0039] When using the inductor transfer auxiliary tooling of this application, first place it on the hydraulic lifting transport vehicle, then start the hydraulic lifting transport vehicle to slowly rise and gradually approach the inductor. During this period, the maintenance worker manually moves the inductor transfer auxiliary tooling according to experience until the elongated mounting hole 4 of the upper square frame 1 matches the mounting hole on the inductor. Finally, the two are fixed together with bolts. Then, the inductor is removed and the hydraulic lifting vehicle is lowered. The inductor can then be transported to the maintenance workshop for repair using the hydraulic lifting vehicle.

[0040] This application presents a transfer auxiliary tooling constructed from an upper square frame 1, a lower square frame 2, and a connecting plate. The structure is simple and easy to manufacture. It can be made into a cylindrical or frustum-shaped structure according to actual needs, ensuring that the transfer tooling structure can penetrate deeply into the electrical equipment box to contact the inductor. This facilitates disassembly and subsequent transfer operations with the inductor, improving the operability and practicality of the transfer tooling structure.

[0041] This application is equipped with multiple anti-tipping support feet 3. The fan-shaped structure can increase the contact area between the transfer auxiliary tool and the hydraulic lifting vehicle, improve the overall stability, and reduce the risk of tipping. The vertical plate can reconnect the connecting plate, the upper square frame 1 and the lower square frame 2 together, which plays a reinforcing role and improves the firmness. At the same time, it minimizes the use of materials, reduces costs, and facilitates promotion and application.
