Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation, in particular to an acceleration device for a rail vehicle and a rail vehicle component. Background Art

[0002] During the operation of rail vehicles, especially when facing special sections such as uphill or sections with large wind resistance, the power demand of the vehicle will increase significantly. Traditional rail vehicles have insufficient traction due to the adhesion coefficient. The power unit often cannot meet the power demand in these situations, resulting in a reduction in vehicle speed, affecting operational efficiency and passenger experience.

[0003] To solve this problem, the traditional solution is to equip rail vehicles with power units with larger loads to cope with the power requirements under various road conditions. However, this approach has significant shortcomings. First, oversized power units mean higher manufacturing costs and energy consumption, which undoubtedly adds unnecessary burdens to daily operations. Second, under most normal road conditions, these large-load power units cannot be fully utilized, resulting in a waste of resources.

[0004] In the prior art, vehicles using wheels and rails have insufficient traction due to the adhesion coefficient, which leads to slow starting and difficulty in climbing. The utility model improves the starting, acceleration and climbing operation of wheel-rail vehicles by adding a thrust acceleration device independent of the wheels and rails. Utility Model Content

[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0042] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0043] In order to solve the problem in the prior art that the power of a rail vehicle is insufficient or a power device with a large load is provided, which leads to increased costs, an embodiment of the utility model provides an acceleration device for a rail vehicle.

[0044] refer to Figure 1-6 As shown, the acceleration device for a rail vehicle provided by the utility model comprises a driving unit 1 and an acceleration guide rail 2 .

[0045] Specifically, the acceleration guide rail 2 includes a guide rail body 20 and a plurality of U-shaped baffles 22. A mounting groove 21 is provided on the upper end surface of the guide rail body 20 along its axial direction. A plurality of U-shaped baffles 22 are arranged in the mounting groove 21 at intervals along the axial direction. The opening direction of the U-shaped baffles 22 is arranged in the same direction as the opening direction of the mounting groove. Such an arrangement can ensure that when the drive unit 1 is installed in the mounting groove 21, the piston 11 can be arranged in the space surrounded by the plurality of U-shaped baffles 22.

[0046] The driving unit 1 includes a slider 12 and a piston 11 connected to the slider. The slider 12 is slidably arranged on the groove wall of the mounting groove 21. The slider 12 is provided with a water inlet 121, and the water inlet 121 is used to introduce high-pressure water to form a sealed water wall between the U-shaped baffle 22 adjacent to the water inlet and the slider 12.

[0047] It should be noted that the high-pressure water is refracted by hitting the groove wall of the installation groove 21, hits the U-shaped baffle 22 adjacent to the water inlet 121, and splashes along the plane where the U-shaped baffle 22 is located, thereby forming the sealing water wall between the U-shaped baffle 22 adjacent to the water inlet 121 and the slider 12.

[0048] Of course, the high-pressure water may also directly hit the U-shaped baffle 22 near the water inlet 121 and splash along the plane where the U-shaped baffle 22 is located, thereby forming the sealing water wall between the U-shaped baffle 22 near the water inlet 121 and the slider 12 .

[0049] Furthermore, the piston 11 is arranged in a space surrounded by a plurality of the U-shaped baffles 22, and a liquid flow channel 111 and a gas flow channel 112 are provided on the piston 11. The liquid flow channel 111 is used to introduce high-pressure water between the piston 11 and the U-shaped baffle 22 located directly below the piston 11, and the introduced high-pressure water can form a water seal between the two.

[0050] The liquid flow channel 111 is also used to introduce high-pressure water between the piston 11 and the groove wall of the mounting groove 21 to form a water seal. It can be understood that the liquid flow channel 111 can also provide high-pressure water between the mounting groove 21 and the drive unit 1. This part of water can play a lubricating role when the drive unit 1 moves relative to the groove wall of the mounting groove 21.

[0051] The U-shaped baffle 22, the drive unit 1, the groove wall of the installation groove 21 and the sealed water wall can enclose a sealed cavity. This design utilizes the fluidity and sealing properties of water to create a dynamic and closed environment. The gas flow channel 112 is used to fill the sealed cavity with high-pressure gas, thereby increasing the pressure in the sealed cavity. When the high-pressure gas releases the pressure, it can cause the piston 11 to move, thereby driving the slider 12 to slide on the groove wall. This method of converting the increased pressure into power can push the slider 12 to slide on the installation groove 21, thereby pushing the rail vehicle connected to the slider 12 to run, so as to achieve vehicle acceleration.

[0052] Further, refer to Figure 3-4 The best display is that the distance between any two adjacent U-shaped baffles 22 is less than the length of the piston 11 in the axial direction (corresponding to Figure 3 Such a configuration is more conducive to the high-pressure water introduced from the piston 11 to collide with the U-shaped baffle 22 located directly below the piston 11, thereby forming the water seal therebetween.

[0053] It can be understood that when the spacing between any two adjacent U-shaped baffles 22 is smaller than the length of the piston 11 in the axial direction, it can be ensured that when the piston 11 is located at any position in the space surrounded by the multiple U-shaped baffles 22, it can be ensured that at least one U-shaped baffle 22 is located below the piston 11, and when high-pressure water flows out from the liquid flow channel 111 on the piston 11 and collides with the U-shaped baffle to generate refraction or reflection, the refracted or reflected high-pressure water can form a water seal between the U-shaped baffle 22 and the piston 11.

[0054] As a preferred embodiment, the plane where the U-shaped baffle 22 is located is perpendicular to the axial direction (i.e. Figure 3 direction of the y-axis).

[0055] Such a configuration is more conducive to the high-pressure water introduced into the piston 11 and the high-pressure water introduced into the water inlet 121 of the slider 22 to collide with the corresponding U-shaped baffle 22 .

[0056] As a preferred embodiment, refer to Figure 2 , 3 is the best display, in this embodiment, the installation groove 21 has two groove side walls 211 arranged opposite to each other, each of the groove side walls is provided with a guide groove 212 opening toward the inside of the installation groove, and the two sides of the slider 12 (corresponding to Figure 3 The two sides in the horizontal direction, that is, the two sides in the x-axis direction) are respectively slidably disposed in the two guide slots 212.

[0057] refer to Figure 2 As shown in FIG. 3 , preferably, the two guide slots 212 are symmetrically arranged on the two groove side walls 211 . Such an arrangement can ensure that both sides of the slider 12 can slide smoothly in the two guide slots 212 .

[0058] Furthermore, the end surfaces of both ends of the U-shaped baffle 22 are flush with the inner side of the slot side wall 2121 located at the lower side of the guide slot 212. With such a configuration, when the slider 12 slides in the guide slot 212, the distance between the U-shaped baffle 22 and the slider 12 is as small as possible, which is conducive to the high-pressure water forming a water seal between the two, and preventing the high-pressure gas from leaking when the high-pressure gas rushes into the closed cavity, thereby affecting the power output.

[0059] Further, refer to Figure 4-6 As shown, the water inlet 121 includes a cylindrical through hole provided on the slider 12, and the axial direction of the cylindrical through hole intersects the axial direction of the mounting groove 21 at an acute angle. Figure 4 The angle of angle a is between 0 and 90 degrees. This arrangement allows part of the high-pressure water to directly collide with the U-shaped baffle 22. Figure 4 As best shown in FIG. 1 , high-pressure water is sprayed along direction b onto the U-shaped baffle 22 located below it, and is blocked by the U-shaped baffle 22 to form the sealed water wall.

[0060] Next, refer to Figure 6 As shown, optionally, the lower surface of the slider 12 has two sides that are relatively arranged along the axial direction of the mounting groove 21 (that is, the direction of the y-axis in the figure), the piston 11 is arranged on the lower surface and close to the first side thereof, and the high-pressure gas storage 111 is arranged to transport high-pressure gas toward the second side. Such an arrangement can ensure that there is enough space under the slider 12 to form the enclosed space.

[0061] More preferably, reference Figure 3As shown in , a recessed portion 113 is provided on the surface of the piston 11 facing the second side, and the gas flow channel 112 runs through the bottom of the recessed portion 113 and is connected to the inside of the recessed portion 113. In this way, the recessed portion 113 forms a bell mouth, which is conducive to the high-pressure gas flowing out of the gas flow channel 112 flowing into the inside of the sealed cavity evenly along the bell mouth. When the high-pressure gas in the sealed cavity releases pressure, it can evenly transmit force to the piston 11 and the slider 12, so as to better drive the vehicle to accelerate.

[0062] Specifically, refer to Figure 4 5. The gas flow channel 112 includes a gas flow channel inlet 1121, through which a high-pressure gas storage device on the vehicle can fill the piston 11 with high-pressure gas. The gas flow channel 112 also includes a gas flow channel outlet 1122. The gas flow channel 112 penetrates the piston 11 and the outlet of the gas flow channel 1122 is located at the bottom of the recessed portion 113.

[0063] It should be noted that the installation groove 21 has an entry end for the drive unit 1 to enter, and among the multiple U-shaped baffles located in the installation groove 21, there is a first U-shaped baffle disposed close to the entry end, and there is a predetermined distance between the first U-shaped baffle and the entry end. When the drive unit 1 enters the installation groove 21 from the entry end, the installation groove 21 can guide the introduction unit entering therein.

[0064] Next, return Figure 4-5 The liquid flow channel 111 includes a water collecting portion 1111 and a plurality of water outlet holes arranged in the piston 11. The plurality of water outlet holes include a plurality of first water outlet holes 1112 for conveying high-pressure water from the water collecting portion to between the piston and the groove wall. The plurality of water outlet holes also include a plurality of second water outlet holes 1113 for conveying high-pressure water from the water collecting portion to between the piston and the U-shaped baffle.

[0065] The water collecting portion 1111 can store high-pressure water in the piston 11 and maintain the pressure of the high-pressure water in a stable high-pressure range. The high-pressure water can be sprayed to the outside of the piston 11 through the water outlet hole.

[0066] It should be noted that the liquid flow channel 111 further includes a liquid flow channel inlet 1114 , and a high-pressure water reservoir located on the vehicle can fill the water collecting portion 1111 with high-pressure water from the liquid flow channel inlet 1114 .

[0067] An embodiment of the utility model further provides a rail vehicle assembly, which includes a rail vehicle, at least two running rails for the rail vehicle to run, and the acceleration device of the rail vehicle as described above, at least two of the running rails are arranged parallel to the acceleration rail, the acceleration rail and at least two of the running rails are arranged at intervals in a direction perpendicular to the acceleration rail, and the slider 12 is connected to the rail vehicle.

[0068] It is understandable that the acceleration rail and the running rail are both fixed at predetermined positions. When the rail vehicle travels to the predetermined position, the slide block 12 can be matched with the mounting groove 21 .

[0069] Further, refer to Figure 2-3 As best shown, the slider 12 is connected to the rail vehicle through a connecting member 122, and the connecting member 122 includes a mounting seat 1221 and a connecting rod 1222 arranged on the upper surface of the slider, one end of the connecting rod 1222 is connected to the mounting seat 1221, and the other end is connected to the rail vehicle, and the connecting rod 1222 can adjust its position relative to the mounting seat 1221, so that the drive unit 1 can run in the mounting groove 21.

[0070] It can be understood that the vehicle is provided with a high-pressure gas reservoir connected to the gas flow passage, and a high-pressure water reservoir connected to the liquid flow passage.

[0071] In summary, the embodiments of the present invention achieve the following technical effects:

[0072] High-pressure water flows in from the water inlet 121 on the slider 12 and collides with the U-shaped baffle 22 adjacent to the water inlet 121 to form a sealed water wall. The high-pressure water introduced by the liquid flow channel 111 on the piston 11 forms a water seal between the piston 11 and the U-shaped baffle directly below the piston 11.
