Description

Technical Field

[0001] The utility model relates to the field of train brakes, in particular to an electric brake for train wheels. Background Art

[0002] A train, also known as a railway train, refers to a vehicle that travels on railway tracks. It is usually composed of multiple carriages and is one of the important modern means of transportation for mankind. When the power plant unloads coal, the locomotive pulls a fully loaded train over. When it stops to unload coal, each carriage is separated and disconnected to start unloading coal, and the locomotive no longer pulls. At this time, each section is turned over and unloaded, and the empty carriage is placed on an empty car line after each section is unloaded. After a train is completely unloaded, these empty carriages are connected together and then towed by the locomotive.

[0003] At present, the locomotive is equipped with a pneumatic braking device, and the carriages are connected by brake air pipes. However, when the locomotive is separated from the train carriage and the train carriage is stopped on the empty track, it cannot brake autonomously. If strong winds blow directly along the train track, the train carriage may be blown and cause the train to slip, which is quite dangerous. Utility Model Content

[0004] The purpose of the utility model is to provide an electric brake for train wheels, so as to solve the problem mentioned in the background technology that when a train encounters strong winds during operation and stops at a station, the train carriage stops on the track, and the strong wind blows directly along the train track, which may blow the train and cause the train to slip.

[0006] The utility model provides an electric brake for a train wheel, comprising a plurality of boxes arranged side by side and fixed on the ground, each of which is provided with a rotatable worm wheel and a worm, the worm wheel and the worm are meshed, and each two adjacent worms are connected by a transmission shaft, wherein the worm in the box at one end is connected to the output end of a motor through the transmission shaft, and the motor is fixed on the ground;

[0007] The worm gear is rotatably connected to the left and right walls of the box body through a rotating shaft. Guide tubes are provided on the left and right walls of the box body. Threaded rods are provided in the guide tubes. The rotation directions of the threaded rods on both sides are opposite. One end of the threaded rod is connected to the rotating shaft, and the other end is threadedly matched with a square push rod. The push rod is provided with a threaded hole engaged with the threaded rod. The push rod is slidably engaged in the guide tube, and a vertically arranged electric telescopic rod is provided at one end of each push rod away from the threaded rod. The telescopic ends of the electric telescopic rods on the same side are connected to the brake rail.

[0008] Furthermore, a cover plate is provided on the box body, and the cover plate is connected to the box body via a first bolt.

[0009] Furthermore, the brake rail is connected to the electric telescopic rod through a second bolt.

[0010] Furthermore, the motor is arranged in a fixed box, and the fixed box is fixed on the track.

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

[0012] The utility model can prevent a train from stopping on a rail and causing the train to slip when a strong wind blows the train, and has the advantages of simple structure, convenient operation and strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1As shown, this embodiment discloses an electric brake for a train wheel, comprising a plurality of boxes 1 arranged side by side and fixed on the ground, each box 1 is provided with a rotatable worm wheel 2 and a worm 3, the worm wheel 2 and the worm 3 are meshed, and every two adjacent worms 3 are connected by a transmission shaft 4, wherein the worm 3 in one end of the box 1 is connected to the output end of a motor 5 through the transmission shaft 4, and the motor 5 is fixed on the ground;

[0022] The worm gear 2 is rotatably connected to the left and right walls of the box body 1 through the rotating shaft 6. Guide tubes 7 are provided on the left and right walls of the box body 1. Threaded rods 8 are provided in the guide tubes 7. The rotation directions of the threaded rods 8 on both sides are opposite, which can ensure that the push rods 9 at both ends of the threaded rods 8 are retracted and extended at the same time. One end of the threaded rod 8 is connected to the rotating shaft 6, and the other end is threadedly matched with a square push rod 9. The push rod 9 is provided with a threaded hole 901 engaged with the threaded rod 8. The push rod 9 is slidably connected in the guide tube 7. A vertically arranged electric telescopic rod 10 is provided at one end of each push rod 9 away from the threaded rod 8, and the telescopic ends of the electric telescopic rods 10 on the same side are connected to the brake rail 11.

[0023] In this embodiment, a cover plate 12 is provided on the box body 1 , and the cover plate 12 is connected to the box body 1 via a first bolt 13 . The cover plate 12 is detachable, so that the parts in the box body 1 can be repaired or replaced conveniently.
