Description

Technical Field

[0001] This utility model relates to the field of rail vehicle technology, and in particular to an anti-collision fixture for rail vehicle bogies. Background Technology

[0002] During the turnover and assembly of rail vehicles, the bogies are at risk of colliding with surrounding components due to limited space in the work area and blind spots in the operating view. In particular, the installation part of the grounding return device is prone to deformation in a collision because of its prominent position and weak stress, which can lead to damage to the insulation layer of the return wire.

[0003] The aforementioned problems increase the costs of unplanned maintenance and parts replacement, reduce the efficiency of maintenance operations, and pose potential risks to the operational safety of equipment. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a collision protection fixture for railway vehicle bogies with good anti-collision effect and simple structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose an anti-collision tooling for a bogie of a rail vehicle, comprising:

[0006] A buffer body, one end of which is a fixed end and the other end is a buffer end; when an external impact acts on the buffer end, the buffer body can be forced to deform.

[0007] A magnet is disposed at the fixed end of the buffer body;

[0008] A flexible protective cover is disposed at the fixed end of the buffer body, and the flexible protective cover covers the magnet;

[0009] The anti-collision fixture is fixed to the bogie by the magnetic force of the magnet, and the flexible protective cover is placed between the magnet and the bogie to prevent the magnet from contacting the bogie.

[0010] Furthermore, the buffer end of the buffer body is provided with multiple buffer protrusions, which can be forced to deform when an external impact is applied to the buffer protrusions.

[0011] Furthermore, the buffer body is cylindrical in shape;

[0012] The outer periphery of the buffer body is provided with multiple buffer grooves along its axial direction. When the buffer end is subjected to an external impact applied along the axial direction of the buffer body, the width of the buffer groove can be forced to narrow.

[0013] Furthermore, the buffer protrusion is configured as a hemispherical shape;

[0014] The buffer end is provided with multiple rings of buffer protrusions, and each ring of buffer protrusions is evenly arranged with the central axis of the buffer body as the center.

[0015] Furthermore, the fixed end of the buffer body is provided with a mounting groove, and the magnet is disposed in the mounting groove;

[0016] The flexible protective cover is installed on the mounting groove.

[0017] Furthermore, the flexible protective cover is made of rubber, and the flexible protective cover is bonded to the fixed end of the buffer body by adhesive or tape.

[0018] Furthermore, the magnet is configured as a magnetic sheet.

[0019] Furthermore, the buffer body is made of nylon.

[0020] Furthermore, the outer wall of the bogie has a connecting lug protruding outwards, and the height of the buffer body is greater than the height of the connecting lug.

[0021] Furthermore, the mounting groove is configured as an oblong groove.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects:

[0023] In this invention, a magnet is provided at the fixed end of the buffer body. The magnetic force provided by the magnet secures the anti-collision fixture to the bogie of the rail vehicle. This magnetic fixation allows for quick installation and disassembly, and its flexible fixing position can adapt to different workstation requirements. Furthermore, a flexible protective cover is provided at the fixed end of the buffer body, covering the magnet. When the anti-collision fixture is fixed to the bogie, the flexible protective cover acts as a barrier between the magnet and the bogie, directly contacting the surface of the bogie while preventing the magnet from contacting the surface. This ensures both a firm magnetic adhesion and prevents scratches or magnetic damage to the paint layer on the bogie surface. When an external impact acts on the buffer end of the buffer body, the nylon buffer body deforms, absorbing the collision energy. Once the anti-collision fixture is fixed to the bogie of the rail vehicle, it provides effective protection for the bogie during handling and installation, preventing collision damage and other problems.

[0024] In this invention, multiple buffer protrusions are provided at the buffer end of the buffer body. When an external impact acts on the buffer end, the buffer protrusions are forced to deform and absorb the collision energy. The buffer protrusions enhance the buffering effect of the buffer body. Furthermore, the buffer protrusions are arranged in multiple rings in a hemispherical shape, resulting in good energy absorption during collisions, reducing stress concentration, and extending service life.

[0025] In this invention, the buffer body is cylindrical, and multiple buffer grooves are arranged sequentially along its axial direction on its outer periphery. When the buffer end of the buffer body is subjected to an external impact applied along its axial direction, the buffer body will deform, the width of the buffer groove will narrow, absorb the collision energy, and further improve the energy absorption effect of the buffer body.

[0040] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.

[0041] like Figures 1-6 As shown, an anti-collision fixture for a railway vehicle bogie in this embodiment mainly includes: a buffer body 1, a magnet 2, and a flexible protective cover 3.

[0042] One end of the buffer body 1 is set as a fixed end 11, which is fixed to the bogie of the rail vehicle during use; the other end is set as a buffer end 12. When an external impact acts on the buffer end 12, it can force the buffer body 1 to deform, that is, the buffer body 1 can absorb the collision energy through deformation.

[0043] Magnet 2 is installed at the fixed end 11 of the buffer body 1. The magnetic force provided by magnet 2 makes it easy for the fixed end 11 to be firmly fixed on the bogie.

[0044] A flexible protective cover 3 is provided at the fixed end 11 of the buffer body 1, and the flexible protective cover 3 covers the magnet 2;

[0045] In actual use, the tooling is attracted to the bogie by the magnetic force of magnet 2, and the anti-collision tooling is fixed to the bogie. The flexible protective cover 3 is placed between magnet 2 and bogie, so that magnet 2 does not contact bogie. That is, the flexible protective cover 3 directly contacts the surface of bogie, while magnet 2 does not contact bogie, ensuring that the paint layer on the surface of bogie will not be scratched or magnetically damaged.

[0046] As a preferred embodiment, the buffer body 1 is made of nylon (polyamide fiber, also known as PA), which is a high-toughness nylon material with good energy absorption and cushioning properties. It can effectively absorb external impact energy and prevent the bogie of the rail vehicle from being damaged by collisions during turnover and installation. Of course, as an energy-absorbing structure, the buffer body 1 can also be made of other materials with good energy absorption effects instead of nylon, which will not be elaborated here.

[0047] In practical use, the anti-collision fixture of this embodiment has a magnet 2 at the fixed end 11 of the buffer body 1. The magnet 2 provides magnetic force to fix the anti-collision fixture to the bogie of the rail vehicle, employing magnetic fixation for quick installation and disassembly. Installation and disassembly are convenient, and its fixing position is flexible to adapt to different workstation requirements. Furthermore, a flexible protective cover 3 is provided at the fixed end 11 of the buffer body 1, covering the magnet 2. When the anti-collision fixture is fixed to the bogie, the flexible protective cover 3 acts as a barrier between the magnet 2 and the bogie, directly contacting the surface of the bogie while preventing the magnet 2 from contacting the surface. This ensures both a firm magnetic attraction of the magnet 2 and prevents scratches or magnetic damage to the paint layer on the bogie surface. When an external impact acts on the buffer end 12 of the buffer body 1, the nylon buffer body 1 deforms, absorbing the collision energy. Once the anti-collision fixture is fixed to the bogie of the rail vehicle, it provides effective protection for the bogie during turnover and installation, preventing collision damage and other problems.

[0048] like Figure 1 and Figure 3 As shown, in this embodiment, the buffer end 12 of the buffer body 1 is provided with multiple buffer protrusions 120. When an external impact acts on the buffer protrusions 120, it can force the buffer protrusions 120 to deform, and the deformation of the buffer protrusions 120 can absorb part of the collision energy. The buffer body 1 is cylindrical, and the cylindrical nylon material is readily available, making the manufacture of the buffer body 1 convenient. Nylon material itself has good toughness, and the cylindrical shape can better exert its energy absorption and buffering effect, effectively absorbing collision energy.

[0049] The buffer protrusions 120 are hemispherical, and their spherical surface disperses concentrated point impact forces, preventing stress concentration. The spherical surface also lacks sharp edges, making it less likely to scratch the surface of the object it collides with. Furthermore, the buffer end 12 of the buffer body 1 has multiple rings of buffer protrusions 120, with each ring containing multiple protrusions 120. These protrusions are evenly distributed around the central axis of the buffer body 1, providing cushioning from all directions. The spacing between the buffer bodies 1 near the inner ring is smaller, while the spacing between the buffer bodies 1 near the outer ring is larger; that is, the center distance is small, and the outer distance is large. This is because, typically during a collision, the central area receives a more direct and concentrated impact, while the outer area experiences relatively less and more dispersed force. The buffer protrusions 120 being densely packed in the center and dispersed on the outside better adapts to real-world collision scenarios, improving the cushioning effect of the buffer body 1.

[0050] Furthermore, in this embodiment, multiple buffer grooves 100 are sequentially arranged around the outer periphery of the buffer body 1 along its axial direction. The multiple buffer grooves 100 are arranged at equal intervals. When the buffer end 12 is subjected to an external impact F applied along the axial direction of the buffer body 1, the width of the buffer groove 100 can be forced to narrow, and the buffer body 1 absorbs the collision energy.

[0051] In practical use, this embodiment provides multiple buffer protrusions 120 on the buffer end 12 of the buffer body 1. When an external impact acts on the buffer end 12, the buffer protrusions 120 are forced to deform, absorbing the collision energy. The buffer protrusions 120 enhance the buffering effect of the buffer body 1. Furthermore, the buffer protrusions 120 are arranged in multiple rings, forming a hemispherical shape, resulting in good energy absorption during collisions and reducing stress concentration, thus extending service life. Additionally, the buffer body 1 is cylindrical, with multiple rings of buffer grooves 100 sequentially arranged along its axial direction on its outer periphery. When the buffer end 12 of the buffer body 1 is subjected to an external impact applied along its axial direction, the buffer body 1 deforms, narrowing the width of the buffer grooves 100, absorbing the collision energy, and further enhancing the energy absorption effect of the buffer body 1.

[0052] It should be explained that a connecting lug (not shown in the figure) protrudes from the outer wall of the bogie of the rail vehicle. This connecting lug is the installation location of the grounding return device. Because it protrudes, it is prone to deformation in a collision. In this embodiment, the height of the buffer body 1 is set to be greater than the height of the connecting lug. Furthermore, when in use, the anti-collision fixture can be attracted to the position near the connecting lug by the magnet 2, effectively protecting the connecting lug and ensuring that the connecting lug will not be deformed or damaged in a collision.

[0053] like Figure 2 Figures 4-6As shown, in this embodiment, the fixed end 11 of the buffer body 1 is provided with a mounting groove 110. The mounting groove 110 is waist-shaped. The waist-shaped mounting groove 110 does not form sharp corners, avoiding stress concentration and shortening the service life of the buffer body 1. The magnet 2 is disposed in the waist-shaped mounting groove 110. In this embodiment, the magnet 2 is preferably disposed as a magnetic sheet. Two magnetic sheets are symmetrically disposed in the waist-shaped mounting groove 110. The magnetic sheets can ensure that the anti-collision fixture is firmly attached to the surface of the bogie, while ensuring that the magnetic force is not too strong, so as to avoid inconvenience in disassembly and assembly or damage to the surface of the bogie.

[0054] The flexible protective cover 3 is preferably made of rubber, rather than a rigid material, as a rigid protective cover can easily scratch or damage the paint layer on the bogie. Furthermore, the flexible protective cover 3 is bonded to the fixed end 11 of the buffer body 1 with adhesive or tape. The flexible protective cover 3 covers the mounting groove 110, confining the magnet 2 within the mounting groove 110 and preventing the magnet 2 from shifting.

[0055] In practical use, when the bogie needs to be moved or installed, the anti-collision fixture is fixed to the outer surface of the bogie. Magnet 2 provides the attraction force, but it is in contact with the surface of the bogie through the flexible protective cover 3, while magnet 2 does not make contact. When an external impact F acts on the buffer end 12 along the axial direction of the buffer body 1, the buffer protrusion 120, the buffer groove 100, and the buffer body 1 itself deform, absorbing the impact energy in multiple ways, thus effectively protecting the bogie and preventing damage to the return device and main wire insulation layer caused by the collision; reducing rework and component replacement, lowering maintenance redundancy costs, and achieving significant economic benefits; improving the first-time success rate of maintenance operations, shortening working time, and significantly improving efficiency; promoting the standardization of anti-collision fixtures and the standardization of processes, further enhancing the effectiveness of lean production, and enabling lean production to be implemented.

[0056] In this solution, the anti-collision tooling has a good anti-collision effect, simple structure, convenient disassembly and assembly, flexible application, and wide applicability.
