Description

Technical Field

[0001] The utility model relates to the technical field of skirt boards, and particularly relates to a skirt board for railway locomotives and vehicles. Background Art

[0002] During the operation of vehicles, the speed is relatively high. To prevent damage to the underbody components caused by environmental factors such as sand, wind, rain, snow, and flying foreign objects, skirt boards are installed under the side walls of the vehicle body to protect other components under the vehicle from being damaged by unknown foreign objects, and to improve the running safety and reliability of the train. Currently, most of the skirt boards used on railway locomotives and vehicles are formed by welding existing steel sections such as angle steel and panels into one body. For the skirt boards with this structure, the angle steel is welded to the panel through conventional welding processes. To meet the required strength of the skirt board, a large amount of angle steel is used, resulting in a relatively thick skirt board, which leads to a large weight of the skirt board. At the same time, the conventional welding method results in low processing accuracy of the skirt board, poor surface quality of the product, and poor surface flatness. Therefore, providing a skirt board with high surface flatness, high strength, and light weight is a problem that needs to be solved by those skilled in the art.

[0003] To solve the above technical problems, Chinese Patent No. CN206983991U in the prior art discloses a skirt board for railway locomotives and vehicles, which includes a rib plate and a panel: the rib plate and the panel are welded into one body: the rib plate adopts a "U" - shaped profile structure, the rib plate includes a longitudinal rib plate and a transverse rib plate and is integrally press - formed, the arc - shaped bending plate and the flat plate of the panel are integrally press - formed, and the rib plate and the panel are also press - formed through a special tooling.

[0004] Although the above - mentioned prior - art solution improves the strength of the skirt board and greatly reduces the raw material thickness of the rib plate and the panel, when the vehicle is running at a high speed, the flying objects from the outside are likely to cause a large impact force on the skirt board, and the impact force will cause local depression and deformation of the skirt board. The integrity of the structure at the depression and deformation part decreases. If it is hit again, it is likely to be damaged, resulting in the exposure of the internal pipeline components, thus affecting the running safety. Content of the Utility Model

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A skirt for railway locomotives and rolling stock includes a skirt frame 1. A panel body 2 is slidably connected to one end of the inner side of the skirt frame 1. A mounting frame 3 is snapped onto one side of the outer wall of the panel body 2 via a positioning component. A deflection wheel 4 is rotatably connected to the inner side of the mounting frame 3. A protective mechanism is installed between the panel body 2 and the skirt frame 1. The protective mechanism includes a sliding retraction component and a buffer component. The sliding retraction component ensures the stability of the panel body 2 when it retracts, and the buffer component buffers the impact force transmitted to the panel body 2. In use, this device can ensure the stability of the panel body 2 when it retracts through the sliding retraction component and buffer the impact force transmitted to the panel body 2. It has a simple structure and is easy to operate, further increasing the protective performance of the skirt when the vehicle is traveling at high speed, protecting the internal pipeline components of the vehicle, and improving the practicality of the skirt.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the sliding retraction assembly includes a fixed cover 5 installed on one side of the inner wall of the skirt frame 1. An extension groove is provided on one side of the fixed cover 5. A sliding plate 6 is slidably connected to the inner side of the fixed cover 5. A buffer pad 7 is slidably connected to the other side of the inner wall of the skirt frame 1. The buffer pad 7 is made of rubber. One side of the buffer pad 7 is fixedly connected to one side of the panel body 2. The length of the buffer pad 7 is greater than the length of the panel body 2. An airbag 21 is installed on the inner wall of the skirt frame 1 inside the fixed cover 5. First, when an external object collides with the skirt frame 1 and the panel body 2, the object first contacts the protective sleeve 13 on the multiple sets of deflection wheels 4 on the outer wall of the panel body 2. The protective sleeve 13 deforms to initially relieve the force.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the buffer assembly includes positioning plates 8 installed at both ends of the outer wall of the sliding plate 6 near the extension groove. Spring damping shock absorbers 9 are installed on the opposite surfaces of the two sets of positioning plates 8. First connecting plates 10 are installed on the opposite ends of the two sets of spring damping shock absorbers 9. Second connecting plates 11 are rotatably connected to the opposite ends of the two sets of first connecting plates 10. Then, the impact force continues to be transmitted to the panel body 2, forcing the panel body 2 to move back on the skirt frame 1. At the same time, the buffer pad 7 is subjected to force and moves back at any time. The third connecting plate 12 squeezes the two sets of second connecting plates 11 to deflect. The second connecting plates 11 then squeeze the spring damping shock absorbers 9 to retract and squeeze, and buffer and unload the force again.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, a third connecting plate 12 is rotatably connected between the two sets of second connecting plates 11. The other end of the third connecting plate 12 is fixedly connected to the other side of the buffer pad 7. Multiple sets of protective sleeves 13 are arranged on the outer wall of the deflection wheel 4. The protective sleeves 13 are made of rubber. Furthermore, the sliding plate 6 moves inside the fixed cover 5 to compress the airbag 21 and cooperate with the two sets of spring damping shock absorbers 9 to provide auxiliary buffering, which greatly reduces the impact force generated when the object collides. The deflection wheel 4 is rotatably connected to the inner side of the mounting frame 3 and can also rotate when a collision occurs. When the protective mechanism unloads and buffers, it deflects the direction of the object's movement to move it away from the panel body 2 and the skirt frame 1, which plays an auxiliary buffering and protective role.

[0028] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, the positioning component includes multiple sets of splicing seats 14 arranged and installed on one end of the outer wall of the panel body 2. A locking block 15 is installed on one side of the outer wall of the mounting frame 3. A locking groove is opened on one side of the splicing seat 14. The locking block 15 and the locking groove are slidably connected. An extrusion groove is opened inside the splicing seat 14 on one side of the locking groove. An extrusion plate 18 is slidably connected to the inner side of the extrusion groove. Return springs 16 are installed between both ends of one side of the extrusion plate 18 and the inner wall of the extrusion groove. The cross-section of the extrusion plate 18 is T-shaped, and the cross-section of the locking block 15 is L-shaped. Sloping surfaces are opened at the opposite ends of the locking block 15 and the extrusion plate 18. The slopes of the two sets of slopes are the same. A pull rod 17 is installed on one side of the extrusion plate 18 between the two sets of return springs 16. The pull rod 17 is slidably connected to the splicing seat 14. An operating groove is opened at one end of the top of the splicing seat 14. The pull rod 17 extends to one end inside the operating groove and rotates. A pull ring 19 is connected to the moving part, and a hanging rod 20 is installed on one side of the inner wall of the operating groove. Furthermore, the mounting frame 3 is attached to the splicing seat 14, and the locking block 15 enters the inner side of the locking groove and contacts the extrusion plate 18. The inclined surfaces of the two abut against each other. As the locking block 15 continues to move, the extrusion plate 18 squeezes the two sets of return springs 16 to retract. After the locking block 15 is fully pushed in, the extrusion plate 18 is ejected by the two sets of return springs 16, allowing it to abut against the protruding end of the locking block 15 to fix the position of the deflection wheel 4. When the deflection wheel 4 needs to be removed for inspection and maintenance, the pull ring 19 can be fastened to drive the pull rod 17 to slide inside the splicing seat 14, driving the extrusion plate 18 away from the locking block 15, and the pull ring 19 can be deflected at a certain angle and hung on the hanging rod 20 for temporary positioning. At this time, the deflection wheel 4 can be removed for inspection and maintenance. After separation, the pull ring 19 can be removed from the hanging rod 20.

[0029] The implementation principle of a skirt for railway locomotives and rolling stock according to an embodiment of this application is as follows: When an external object collides with the skirt frame 1 and the panel body 2, the object first contacts the protective sleeves 13 on the multiple sets of deflection wheels 4 on the outer wall of the panel body 2. The protective sleeves 13 deform to initially relieve the force, and the impact force continues to be transmitted towards the panel body 2, forcing the panel body 2 to move back on the skirt frame 1. At the same time, the buffer pad 7 is subjected to force and moves back at any time. The third connecting plate 12 squeezes the two sets of second connecting plates 11 to deflect, and the second connecting plates 11 squeeze the spring damping shock absorbers 9 to retract and squeeze, thus buffering and relieving the force again. The sliding plate 6 moves inside the fixed cover 5 to squeeze the airbag 21 and cooperate with the two sets of spring damping shock absorbers 9 to provide auxiliary buffering, which greatly reduces the impact force generated when the object collides. Moreover, the deflection wheels 4 are rotatably connected to the inner side of the mounting frame 3 and can also rotate when a collision occurs, thus relieving the impact force in the protective mechanism. When the force is buffered, the direction of the object's movement is deflected, causing it to move away from the panel body 2 and the skirt frame 1, which plays an auxiliary buffering and protective role. The mounting frame 3 is attached to the splicing seat 14, and the locking block 15 enters the inner side of the locking groove and contacts the extrusion plate 18. The inclined surfaces of the two abut against each other. As the locking block 15 continues to move, the extrusion plate 18 squeezes the two sets of return springs 16 to retract. After the locking block 15 is fully pushed in, the extrusion plate 18 is ejected by the two sets of return springs 16, allowing it to abut against the protruding end of the locking block 15 to fix the position of the deflection wheel 4. When the deflection wheel 4 needs to be removed for inspection and maintenance, the pull ring 19 can be fastened to drive the pull rod 17 to slide inside the splicing seat 14, causing the extrusion plate 18 to move away from the locking block 15, and the pull ring 19 can be deflected at a certain angle and hung on the hanging rod 20 for temporary positioning. At this time, the deflection wheel 4 can be removed for inspection and maintenance. After separation, the pull ring 19 can be removed from the hanging rod 20.
