Description

Technical Field

[0001] This utility model relates to the field of railway track vehicle technology, and in particular to a railway track walkway device. Background Technology

[0002] Railway vehicle maintenance stations are railway facilities responsible for the inspection, maintenance, and storage of trains. They mainly undertake daily inspections, troubleshooting, cleaning, and maintenance to ensure the safe operation of trains. Vehicles are usually parked in the maintenance station, and maintenance personnel need to complete vehicle inspections and maintenance between the tracks. Therefore, the track walkways are the working surfaces for maintenance personnel to walk and work. Traditional track walkways are made of rubber material laid close to the track bed, which is not only prone to aging but also has poor drainage performance.

[0003] To improve the reliability of trackside walkways, a Chinese utility model patent (publication number: CN211036622U) discloses a walkway slab for track lines, comprising an upper top plate, a lower top plate, and an intermediate core plate. The upper top plate includes a first upper layer of blanks composed of parallel-grained bamboo fiber bundles and a first lower layer of blanks composed of transverse-grained bamboo fiber bundles. This technology mainly achieves the effects of reducing the weight of the device, increasing its service life, and reducing production costs by adjusting the materials and internal structure of the trackside walkway.

[0004] While the aforementioned technology has solved the problems of traditional trackside walkways to some extent, it lacks a drainage structure and is installed on the track bed. Therefore, the existing technology still suffers from poor drainage performance in railway trackside walkways. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a railway maintenance trackside walkway device with a drainage structure that facilitates vehicle maintenance operations by maintenance personnel.

[0006] This utility model is achieved through the following technical solution: a railway maintenance trackway device, including a trackway slab and a fixing frame, wherein drainage holes are evenly arranged through the trackway slab, the fixing frame is a parallel support structure, and the trackway slabs are laid tightly on the fixing frame one by one.

[0007] Preferably, the fixing frame consists of multiple independent and parallel H-beams, the edge of the walkway slab is provided with fixing holes, the fixing frame is provided with connecting holes corresponding to the fixing holes, and the walkway slab and the fixing frame are fixed by connecting parts passing through the fixing holes and connecting holes.

[0008] Preferably, a limiting baffle is provided above the fixing frame, and the distance between the limiting baffles is equal to the width of the walkway slab.

[0009] Furthermore, the side of the walkway slab is provided with a limiting hole, and the limiting baffle is provided with a mounting hole that penetrates the limiting baffle corresponding to the limiting hole. The walkway slab and the fixing frame are fixed by a connector that penetrates the limiting hole and the mounting hole.

[0010] Furthermore, the side of the walkway slab is provided with a limiting hole, and the inner side of the limiting baffle is provided with a limiting protrusion corresponding to the limiting hole. The limiting protrusion is used to snap the limiting hole to fix the walkway slab and the fixing frame.

[0011] Preferably, the drainage holes are uniformly and staggeredly arranged hexagonal hollow structures.

[0012] Furthermore, the inner side of the drainage hole has a downward-sloping surface structure.

[0013] Preferably, the upper surface of the walkway slab is provided with anti-slip texture.

[0014] Preferably, a plug-in block is provided on the front side of the walkway slab, and a plug-in interface is provided on the rear side of the walkway slab, with the plug-in block and the plug-in interface being provided correspondingly.

[0015] Preferably, the fixing frame consists of multiple independent and parallel H-beams, with the width of the lower plane of the H-beams being greater than the width of the upper plane.

[0016] The beneficial effects of this utility model are as follows: This device, through the combination of walkway slabs and fixed frames, enables the laying of a passageway for maintenance personnel in railway track maintenance areas. Drainage holes are provided on the walkway slabs, and the walkway slabs are mounted on the fixed frames, which ensures the overall drainage effect of the device. There is a certain gap between the walkway slabs and the track bed in the part where maintenance personnel walk, which ensures that accumulated water can be drained quickly. In winter, snow can fall directly under the device through the drainage holes, minimizing the impact of precipitation on the use of the device. The walkway slabs and fixed frames are stably connected and fixed by a connecting mechanism, ensuring the reliability of the overall device. Attached Figure Description

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Example

[0024] like Figure 1-2 As shown, a railway maintenance track bed walkway device includes a walkway slab 1 and a fixing frame 2. Drainage holes 3 are evenly arranged through the walkway slab 1. The fixing frame 2 is a parallel support structure. The walkway slabs 1 are laid tightly one by one on the fixing frame 2. The walkway slab 1 is the main working surface for maintenance personnel to walk and operate. By tightly laying multiple independent walkway slabs 1 on the fixing frame 2, a complete walkway for railway maintenance track bed is formed. The combination of walkway slabs and fixing frames realizes the laying of a passage for maintenance personnel in the railway maintenance track bed. The walkway slabs are provided with drainage holes, and the walkway slabs are mounted on the fixing frame to ensure the overall drainage effect of the device. There is a certain gap between the walkway slab and the track bed where maintenance personnel walk, which can ensure that accumulated water is quickly drained away. In winter, snow can fall directly under the device through the drainage holes, minimizing the impact of precipitation on the use of the device. Example

[0025] like Figure 1-2As shown, to ensure the stable fixing of the walkway slab 1 and the fixing frame 2, fixing pins or bolts are used to fix the walkway slab 1 and the fixing frame 2 together. Fixing holes 11 are provided at the edge of the walkway slab 1, and the fixing frame 2 is provided with connecting holes corresponding to the fixing holes 11. The walkway slab 1 and the fixing frame 2 are fixed by connecting parts passing through the fixing holes 11 and connecting holes, which can ensure that the walkway slab 1 will not be displaced. At the same time, a limiting baffle 4 is provided above the fixing frame 2. The limiting baffle 4 is just enough to fit the walkway slab 1, which can prevent the walkway slab 1 from being displaced due to the vibration generated by the train, and can also prevent the side of the fixing hole 11 of the walkway slab 1 from being damaged by excessive force, thereby ensuring the reliability of the device.

[0026] Furthermore, a limiting hole 12 is provided on the side of the walkway slab 1, and a mounting hole is provided on the limiting baffle 4 corresponding to the limiting hole 12 (or a limiting protrusion is provided on the inner side of the limiting baffle 4 corresponding to the limiting hole 12). The walkway slab 1 and the fixing frame 2 are fixed by a connector passing through the limiting hole 12 and the mounting hole (or the limiting protrusion is used to snap the limiting hole 12 to fix the walkway slab and the fixing frame 2). This ensures that the walkway slab 1 will not move forward or backward. Example

[0027] like Figure 1-4 As shown, the drainage holes 3 are uniformly and staggered hexagonal hollow structures, which can not only maximize the hollow area of ​​the walkway slab 1 to ensure that water will not accumulate, but also ensure the compressive strength of the walkway slab 1.

[0028] Meanwhile, the upper inner side of the drainage hole 3 has a downward sloping structure, which can improve the drainage efficiency of the walkway slab 1; the upper surface of the walkway slab 1 is provided with anti-slip texture, thereby ensuring the safety of maintenance personnel walking on the device.

[0029] A plug-in block 5 is provided on the front side of the walkway slab 1, and a plug-in interface 51 is provided on the rear side of the walkway slab 1. The plug-in block 5 and the plug-in interface 51 are set in a corresponding manner to form multiple independent walkway slabs 1 into an integrated load-bearing structure, thereby improving the load-bearing and compressive strength of a single walkway slab 1.

[0030] The fixing frame 2 consists of multiple independent and parallel H-beams. The width of the lower plane of the H-beam is greater than the width of the upper plane to ensure the stability of the fixing frame 2.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
