[0020] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1, as Figures 1 - 4 shown, the present utility model provides an electromagnetic braking device for a rail train, including: a mounting plate 1, support rods 2 are fixedly connected to the bottom corners of the mounting plate 1, and a support plate 3 is fixedly connected between the lower end faces of the plurality of support rods 2; a braking assembly 4, the braking assembly 4 is fixedly connected to the bottom of the support plate 3, the braking assembly 4 includes a plurality of springs 401, a supporting plate 402 is fixedly connected between the lower end faces of the plurality of springs 401, and a plurality of electromagnets 403 are fixedly connected to the bottom of the supporting plate 402 at equal intervals; a release assembly 5, the release assembly 5 is fixedly connected to the top of the supporting plate 402, the release assembly 5 includes a connecting pipe 501 and a bracket 503, a friction plate 404 is fixedly connected to the bottom of the electromagnet 403, a notch is formed in the top of the supporting plate 402, a discharge channel 405 is fixedly connected to the bottom of the supporting plate 402 near the notch, a discharge hopper 406 is fixedly connected to the bottom of the discharge channel 405, the connecting pipe 501 is matched with the position of the discharge channel 405, a storage hopper 502 is fixedly connected to the top of the connecting pipe 501, a side groove 507 is formed on the outer surface of the connecting pipe 501, an electric telescopic rod 504 is fixedly connected to the outer surface of the bracket 503 close to the connecting pipe 501, a connecting plate 505 is fixedly connected to the end face of the electric telescopic rod 504, a baffle 506 is fixedly connected to the outer surface of the connecting plate 505, the baffle 506 is matched with the position of the side groove 507, the outer surface of the baffle 506 is attached to the inner surface of the connecting pipe 501, a storage box 6 is fixedly connected to the top of the support plate 3, the storage box 6 is communicated with the storage hopper 502, and covers 7 are symmetrically hinged to the top of the storage box 6.

[0023] The effect achieved by the entire Embodiment 1 is that when the electromagnetic brake of the rail train is in use, the electromagnetic brake is integrally installed at the bottom of the train carriage through the use of the mounting plate 1. The electromagnet 403 is positioned directly above the rail. The electromagnet 403 is supported by the supporting plate 402 and the spring 401 at the top. When the electromagnet 403 is in the unactivated state, there is a certain distance from the rail. Sand and gravel for providing friction during sandblasting are stored in the storage box 6. When the train needs to make an emergency brake, the electromagnet 403 is activated to generate magnetic suction. At this time, the electromagnet 403 generates an attractive force downward towards the rail. Therefore, the electromagnet 403 moves downward to drive the friction plate 404 into a state of being in contact with the rail. By the friction plate 404 being in contact with the rail surface and generating pressure, it can play a role in increasing the friction force, thereby assisting the train in braking. During the process of the electromagnet 403 being activated for braking, the electric telescopic rod 504 is activated to contract. After the electric telescopic rod 504 contracts, it can drive the baffle 506 to move through the connection of the connecting plate 505. After the baffle 506 moves out of the position of the communicating pipe 501, the position of the communicating pipe 501 loses the obstruction at this time. Therefore, the accumulated sand and gravel above will fall along the communicating pipe 501. The sand and gravel will then fall downward through the connection of the discharge channel 405 and the discharge hopper 406. The sand and gravel will fall from the position of the discharge hopper 406 onto the rail surface. The sand and gravel on the rail surface will come into contact with the friction plate 404 and the wheels. The sand and gravel can form a covering layer with a relatively large friction force on the smooth rail surface, making the friction force relatively large when the friction plate 404 contacts the rail, and being able to assist the train in quickly stopping, improving the use effect of the electromagnetic brake.

[0024] Embodiment 2, as Figures 1 - 4 shown, a storage box 6 is fixedly connected to the top of the support plate 3. The storage box 6 is in a communicating setting with the storage hopper 502. The top of the storage box 6 is symmetrically hinged with cover plates 7.

[0025] The effect achieved by the entire Embodiment 2 is that when storing sand and gravel in the storage box 6, after opening the cover plate 7, the inside of the storage box 6 can be added, making the feeding operation more convenient and fast.

[0026] Working principle: When the electromagnetic brake of the rail train is in use, the electromagnetic brake is integrally installed at the bottom of the train carriage through the use of the mounting plate 1. The electromagnet 403 is positioned directly above the rail. The electromagnet 403 is supported by the supporting plate 402 and the spring 401 at the top. When the electromagnet 403 is in the unactivated state, there is a certain distance from the rail. In the storage bin 6, sand is stored to provide friction for sandblasting. When the train needs to make an emergency brake, the electromagnet 403 is activated to generate magnetic suction. At this time, the electromagnet 403 generates an attractive force downward towards the rail. Therefore, the electromagnet 403 moves downward to drive the friction plate 404 to be in a state of being in contact with the rail. By the friction plate 404 being in contact with the rail surface and generating pressure, it can play a role in increasing the friction force, thereby assisting the train in braking. During the process of the electromagnet 403 being activated for braking, the electric telescopic rod 504 is activated to contract. After the electric telescopic rod 504 contracts, it can drive the baffle 506 to move through the connection of the connecting plate 505. After the baffle 506 moves out of the position of the communicating pipe 501, the position of the communicating pipe 501 is no longer blocked at this time. Therefore, the sand accumulated above will fall along the communicating pipe 501. The sand will then fall downward through the connection of the discharge channel 405 and the discharge hopper 406. The sand will fall from the position of the discharge hopper 406 to the rail surface. The sand on the rail surface will contact the friction plate 404 and the wheels. The sand can form a covering layer with a relatively large friction force on the smooth rail surface, making the friction force relatively large when the friction plate 404 contacts the rail, which can assist the train in quickly braking and improving the use effect of the electromagnetic brake. When storing sand in the storage bin 6, after opening the cover plate 7, the inside of the storage bin 6 can be added, and the feeding operation is relatively convenient and fast.

[0027] The wiring diagrams of the electromagnet 403 and the electric telescopic rod 504 in the present utility model belong to the common knowledge in the field. Their working principles are already known technologies. Their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the electromagnet 403 and the electric telescopic rod 504 will not be explained in detail.

[0028] The above are only the preferred embodiments of the present utility model, and do not limit the present utility model in other forms. Any person skilled in the relevant art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
