Description

Technical Field

[0001] The utility model belongs to the bulk material loading and unloading equipment of railway vehicles, and particularly relates to a novel coupler device. Background Art

[0002] The coupler device is commonly used on the shunting locomotive of the dumper car unloading system. At present, both the front coupler and the rear coupler of the commonly used coupler device are fixed on the boom body through a guide cover and a guide shaft. The front coupler relies on a rubber pad for buffering, and the rear coupler relies on a disc spring for buffering. The disadvantage of this device is that whether the front coupler or the rear coupler is stressed, only a single rubber pad or disc spring is stressed, which requires high stress on the rubber pad and disc spring. In addition, when the front coupler pushes an empty car body, since the coupler on the empty car body has a deflection angle, it is often difficult to hook up. In order to improve the buffering performance of the coupler and the hooking stability of the front coupler, it is very necessary to develop a novel coupler device. Content of the Utility Model

[0003] The utility model aims to provide the buffering performance of the coupler and the hooking stability of the front coupler.

[0004] The purpose of the utility model is realized by adopting the following technical scheme: a novel coupler device, including a front coupler (1), a coupler alignment device (2), a rotary pin shaft (3), a front guide seat (4), a rubber pad (5), a spacer sleeve (6), a disc spring (7), a rear guide cover (8), a rear coupler (9), a front guide shaft (10) and a rear guide shaft (11); the front guide seat (4) is fixed on the boom body (12); the front coupler (1) and the front guide shaft (10) are fixed on the front guide seat (4) through the rotary pin shaft (3); the rear guide cover (8) is fixed on the boom body (12), and the rear coupler (9) is fixed on the rear guide cover (8) through the rear guide shaft (11) and the disc spring (7); the rubber pad (5), the spacer sleeve (6) and the disc spring (7) are arranged in the boom body (12). The front section of the rubber pad (5) is assembled with the front coupler as a whole through the front guide shaft (10), the rear section of the rubber pad (5) is directly installed on the boom body, and the spacer sleeve (6) is installed between the two sections of the rubber pad.

[0005] Furthermore, the coupler alignment device (2) is installed on the front guide seat (4), and the installation direction is determined according to the actual deflection of the coupler. The coupler alignment device (2) contacts the rear part of the front coupler (1) so that the front coupler (1) can rotate around the rotary pin shaft (3), and the magnitude of the force of the coupler alignment device can be adjusted.

[0006] Compared with the prior art, the utility model has the following advantages: 1. The structure is simple and the maintenance is convenient; 2. The stress on the rubber pad and the disc spring is reduced; 3. The connection between the front coupler and the coupler of the empty car body is smooth. Description of the Drawings

[0007] Figure 1 is the front view structural schematic diagram of the specific embodiment of the utility model;

[0008] Figure 2 It is a top view structural schematic diagram of a specific embodiment of the present utility model.

[0009] In the figure: 1. Front hook; 2. Coupler centering device; 3. Rotary pin shaft; 4. Front guide seat; 5. Rubber pad; 6. Sleeve; 7. Disc spring; 8. Rear guide cover; 9. Rear hook; 10. Front guide shaft; 11. Rear guide shaft; 12. Boom body. Specific embodiments

[0010] As Figure 1 and Figure 2 shown, a new type of coupler device, its structure includes a front hook 1, a coupler centering device 2, a rotary pin shaft 3, a front guide seat 4, a rubber pad 5, a sleeve 6, a disc spring 7, a rear guide cover 8, a rear hook 9, a front guide shaft 10 and a rear guide shaft 11; the front guide seat 4 is fixed on the boom body 12; the front hook 1 and the front guide shaft 10 are fixed on the front guide seat 4 through the rotary pin shaft 3; the rear guide cover 8 is fixed on the boom body 12, and the rear hook 9 is fixed on the rear guide cover 8 through the rear guide shaft 11 and the disc spring 7; the rubber pad 5, the sleeve 6 and the disc spring 7 are arranged in the boom body 12, the front section of the rubber pad 5 is assembled with the front hook through the front guide shaft 10, the rear section of the rubber pad 5 is directly installed on the boom body, and the sleeve 6 is installed between the two sections of the rubber pad. The coupler centering device 2 is installed on the front guide seat 4, and the installation direction is determined according to the actual deflection of the coupler. The coupler centering device 2 contacts the rear part of the front hook 1 so that the front hook 1 can rotate around the rotary pin shaft 3, and the magnitude of the force of the coupler centering device is adjustable.

[0011] Its working principle is as follows: when the front hook 1 pushes an empty car body and is stressed, the acting force is transmitted to the rubber pad 5 through the front guide shaft 10 and the sleeve 6. After the rubber pad 5 is compressed, it contacts the rear guide shaft 11 and transmits the force to the disc spring 7 all the time, that is, the force received by the front hook 1 is jointly borne by the rubber pad 5 and the disc spring 7 fixed in the boom body 12. When the rear hook 9 brakes when towing a whole train of heavy cars, the acting force is first transmitted to the disc spring 7, and then the rubber pad 5 will be compressed through the rear guide shaft 11, that is, the force when the rear hook 9 brakes is jointly borne by the rubber pad 5 and the disc spring 7 fixed in the boom body 12. When the front hook 1 pushes an empty car body, the coupler centering device 2 will rotate the coupler by an angle through the rotary shaft 3, so that the front hook can adapt to the deflection of the coupler of the empty car body and hook up smoothly.

[0012] The above is only a specific and preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
