Method and device for increasing adhesion force between wheel and rail of rail vehicle

Abstract

The invention relates to a method for increasing the adhesion between wheels of rail vehicles and tracks. When an idling tendency is about to appear in rail vehicles and friction needs to be increased, a tackifying device leans on the surfaces of rotating wheels, and a tackifying material on the tackifying device is adhered to wheel treading surfaces during the friction process of leaning the tackifying device on the surfaces of the rotating wheels, and the adhesion conditions of contact points are improved to increase the adhesion coefficient between wheel pairs and the tracks, thus inhibiting and preventing idling. By means of coating wheel rolling surfaces with the tackifying material, the adhesion coefficient between wheel pairs and the tracks can be changed, thereby inhibiting and preventing idling. The method and the device involved in the invention have the characteristics of convenient operation and good effect, and are free of the problems that spread sand are likely to roll out of tracks to influence the tackifying and cause environmental pollution and the like.

Description

technical field [0001] The invention relates to a method and a device for preventing rail vehicle wheels and rails from slipping, in particular to a method and a device for increasing the adhesive traction force between rail vehicle wheel sets and rails. The method and the device can replace locomotive sanding to increase the adhesion traction between the rail vehicle wheel set and the rail. The utility model belongs to the technical field of rail vehicles, and is mainly used in railway locomotives, and can also be used for preventing wheel idling of other rail vehicles. Background technique [0002] In the field of rail transit, the locomotive in front of the train relies on the power of the locomotive to move the wheels forward through a series of complex power conversion and transmission. When the wheels run on the rails, due to various factors of the locomotive structure, track structure, environment and wheel-rail contact surface, the wheels do not pass the rails in a ...

AI Technical Summary

Problems solved by technology

[0005] 1. A large number of frequent sanding will not only pollute the environment, but also affect the transmission of track electrical signals;

[0006] 2. A large number of frequent sanding increases the resistance of the train behind and increases the running noise; it is also unfavorable to the rolling bearings of the wheels;

Seriously affected the full use and exertion of traction force;

[0009]5. The effect of sand spreading is poor when driving at high speed. The reason is that the train has a certain air flow, and the sand cannot be successfully sprinkled between the wheels and rails; it can enter the wheel , the sand that acts between the rails is less than 1 / 10 of the entire amount of sand

In the case of frozen ice, snow, and heavy oil pollution on the rail surface, the sanding effect is not good;

[0010] 6. During the sand spreading process, very little sand enters the surface of the rail, and most of the sand accumulates on both sides of the rail, which needs to be cleaned up in time, and the cost of roadbed pollution caused by sand spreading is relatively high;

[0011] 7. The treatment of sand: such as sand drying, cleaning, recycling and storage, and locomotive sanding all need a lot of manpower and material resources;

[0012] 8. A large number of frequent sanding accelerates the wear of the wheel and rail
