Technical Field

[0001] This utility model relates to the field of railway maintenance tools, specifically a wheel-stopping device for railway vehicles. Background Technology

[0002] Railway transportation is a mode of land transportation in which locomotives pull trains that travel on two parallel rails. The rails provide an extremely smooth and hard medium on which the train wheels roll with minimal friction.

[0003] To improve the stability of railway vehicles when they are stopped, wheel-stopping devices are needed to position the vehicles during maintenance. However, the existing wheel-stopping devices have a relatively simple structure and can only squeeze and limit the wheels. When subjected to excessive compression, they will slip and displace, thus failing to achieve the wheel-stopping effect.

[0004] Therefore, it is necessary to redesign and modify the wheel-stopping devices used in railway vehicles. Utility Model Content

[0008] As a preferred embodiment of this utility model, the left and right sides of the top of the screw sleeve are movably connected to rollers via pins, and the outer surface of the rollers is in contact with the surface of the extension plate.

[0009] In a preferred embodiment of this invention, a baffle is fixedly connected to the front of the upright plate, and the screw, screw sleeve, and chuck are all located on the back of the baffle.

[0010] As a preferred embodiment of this invention, the surface of the baffle is provided with a limiting groove, and the front of the threaded sleeve is fixedly connected to a limiting rod located inside the limiting groove, and the limiting rod and the limiting groove are slidably connected.

[0012] As a preferred embodiment of this utility model, a support plate is fixedly connected to the front of the wheel stop, and the side of the support plate away from the wheel stop extends to the front of the clamping plate and is movably connected to the clamping plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 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 protection scope of the present utility model.

[0021] like Figures 1 to 3 As shown, the present invention provides a wheel stop device for railway vehicles, including a wheel stopper 1;

[0022] The left and right sides of the front of the wheel stopper 1 are movably connected to the clamping plate 2 by the pin. The top and bottom of the front of the wheel stopper 1 are fixedly connected to the upright plate 3. The top of the upright plate 3 is provided with a rotating wheel 4. The bottom of the rotating wheel 4 is fixedly connected to the screw 5 located inside the upright plate 3. The surface of the screw 5 is threaded with a threaded sleeve 6. The top of the clamping plate 2 is fixedly connected to the extension plate 7. The top of the threaded sleeve 6 contacts the bottom of the extension plate 7.

[0023] refer to Figure 3 Rollers 8 are movably connected to the top left and right sides of the screw sleeve 6 via pins, and the outer surface of the rollers 8 is in contact with the surface of the extension plate 7.

[0024] As a technical optimization of this utility model, by setting the roller 8, the screw sleeve 6 can be protected, reducing the wear caused by the contact friction between the screw sleeve 6 and the limiting plate.

[0025] refer to Figure 2 A baffle 9 is fixedly connected to the front of the upright plate 3, and the screw 5, the screw sleeve 6 and the claw are all located on the back of the baffle 9.

[0026] As a technical optimization of this utility model, by setting the baffle 9, the safety of the wheel stopper 1 can be improved, and the user can be prevented from being injured by the structure during the movement.

[0027] refer to Figure 2 A limiting groove 10 is provided on the surface of the baffle 9, and a limiting rod 11 located inside the limiting groove 10 is fixedly connected to the front of the screw sleeve 6. The limiting rod 11 and the limiting groove 10 are slidably connected.

[0028] As a technical optimization of this utility model, by setting the limiting groove 10 and the limiting rod 11, the threaded sleeve 6 can be limited, so as to avoid the threaded sleeve 6 tilting during the movement.

[0029] refer to Figure 3 A buffer plate 12 is fixedly connected to the inner side of the clamping plate 2, and the buffer plate 12 is elastic.

[0030] As a technical optimization of this utility model, by setting a buffer plate 12, the squeezing effect of the clamping plate 2 can be improved, and the friction between the clamping plate 2 and the rail can be increased.

[0031] refer to Figure 3 A support plate 13 is fixedly connected to the front of the wheel stopper 1. The side of the support plate 13 away from the wheel stopper 1 extends to the front of the clamping plate 2 and is movably connected to the clamping plate 2.

[0032] As a technical optimization of this utility model, by setting the support plate 13, the clamping plate 2 can be supported, thereby increasing the contact area between the clamping plate 2 and the wheel stopper 1.

[0033] The working principle and usage process of this utility model are as follows: When in use, first place the wheel stopper 1 on the top of the rail and on one side of the wheel. When the wheel stopper 1 is installed, the user rotates the rotating wheel 4, which drives the screw 5 to rotate. The screw 5 uses the thread to push the screw sleeve 6 to move upward. During the movement, the screw sleeve 6 uses the extension plate 7 to squeeze the clamping plate 2. The clamping plate 2 is squeezed and swings around the pin on the surface of the wheel stopper 1. When the inner side of the clamping plate 2 contacts the surface of the rail, the wheel stopper 1 is squeezed and fixed.

[0034] In summary, this wheel-stopping device for railway vehicles can improve the structural functionality of existing wheel-stopping devices, prevent wheel-stopping device 1 from sliding under excessive pressure, and further improve the wheel-stopping effect.
