Description

Technical Field

[0001] The utility model relates to the technical field of sightseeing trains, in particular to a brake assembly for sightseeing trains. Background Art

[0002] As the name suggests, sightseeing trains are used for sightseeing. Generally speaking, they are mainly used in scenic spots, parks, resorts, etc. Unlike our common trains and high-speed trains, this kind of sightseeing train is a special equipment and is only allowed to run on site. There are also speed limit requirements. Different countries have different standards for speed limits.

[0003] Most of the existing sightseeing trains use wrapped calipers for braking, which have a complex overall structure, are not easy to replace and repair the brake discs, and have high usage costs. The brake discs are prone to high temperatures when braking. The sightseeing trains traveling in scenic areas often need to avoid tourists, and the brakes are used frequently. The existing brake assemblies for sightseeing trains do not cool the brake discs, which are prone to brake failures. Utility Model Content

[0004] The purpose of the utility model is to provide a brake assembly for a sightseeing train to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a brake assembly for a sightseeing train, comprising a top plate, four support rods are arranged at the four corners of the bottom end of the top plate, the bottom ends of the four support rods are commonly connected to the bottom plate, a transmission shaft is arranged above the bottom plate, a brake disc is arranged on the outer surface of the transmission shaft, a brake caliper is arranged on the top of the brake disc, an I-shaped support frame is arranged on the top of the brake caliper, a drive rod is arranged on the top of the I-shaped support frame, and an air pump is arranged on the top of the drive rod.

[0006] Preferably, a connecting wire group is provided on the top of the air pump, and the top of the connecting wire group extends out of the top of the top plate. The air pump is connected to a controller provided in the cab of the small train through the connecting wire group. When the cab steps on the brake, the connecting wire group drives the air pump to operate, so as to drive the brake caliper to move downward and contact with the brake disc to generate friction to achieve the braking effect.

[0007] Preferably, two fixed mounting brackets are provided at both end edges of the top plate, so that the brake assembly for the sightseeing train can be installed inside the train, which is convenient to use.

[0008] Preferably, two sleeves are provided at both ends of the I-shaped support frame, and the four sleeves are all sleeved on the surfaces of four support rods. The bottom ends of the sleeves on the outer surfaces of the four sleeves are provided with return springs. When braking, the I-shaped support frame is pressed downward, and the return springs are contracted under the force. After braking is completed, the air pump above the I-shaped support frame retracts the force, and the return spring pushes the I-shaped support frame upward, so that the brake caliper leaves the brake disc.

[0009] Preferably, two cooling nozzles are provided at the top of the bottom plates on both sides of the brake disc, and a cold air circulation pipe is provided on one side of the two cooling nozzles. The cold air circulation pipe is connected to the cold air circulation system of the small train to transport cold air to the brake disc position, thereby reducing the temperature when the brake disc contacts the brake caliper, avoiding excessively high temperature of the brake disc affecting the braking effect, and improving safety.

[0010] Preferably, a rubber block is provided at the bottom end of the brake caliper. When braking, the rubber block will contact both sides of the brake disc. The friction of the rubber block is large, thereby increasing the friction between the brake caliper and the brake disc.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The brake assembly of the sightseeing train pushes the output end of the driving rod to move downward through the thrust generated by the air pump when it is excited, and pushes the I-shaped support frame to move linearly downward. The brake caliper arranged at the bottom end of the I-shaped support frame will contact the brake disc. When the brake caliper contacts the brake disc, the inner wall of the brake caliper and the brake disc generate friction, and the rubber block contacts both sides of the brake disc to increase the friction. The overall structure is simple, and the brake disc and the brake caliper are separated, which is convenient for the inspection and replacement of the brake disc, and the use cost is low.

[0013] 2. The brake assembly of this sightseeing train has two cooling nozzles on both sides of the brake disc. The cooling nozzles are connected to the cold air circulation system of the train through the cold air circulation pipe, which transports cold air to the brake disc position to reduce the temperature when the brake disc contacts the brake caliper, avoid excessively high temperature of the brake disc affecting the braking effect, and improve safety.

[0021] Specifically, a connecting wire group 10 is provided on the top of the air pump 14, and the top of the connecting wire group 10 extends out of the top of the top plate 1. The air pump 14 is connected to a controller set in the cab of the small train through the connecting wire group 10. When the cab steps on the brake, the connecting wire group 10 stimulates the air pump 14 to operate to drive the brake caliper 12 to move downward and contact the brake disc 13 to generate friction to achieve a braking effect.

[0022] Furthermore, two fixed mounting frames 8 are provided at the edges of both ends of the top plate 1, so that the brake assembly for the sightseeing train can be installed inside the train, which is convenient to use.

[0023] Furthermore, two sleeves 3 are provided at both ends of the I-shaped support frame 7, and the four sleeves 3 are all sleeved on the surfaces of the four support rods 2. The bottom ends of the sleeves 3 on the outer surfaces of the four sleeves 3 are provided with return springs 4.
