Adhesion-increasing block for increasing wheel-rail adhesion of rail vehicle and method for making and using it

Abstract

A tackifier block for rail vehicles to increase the adhesion between wheels and rails. The tackifier block is a composite material containing a tackifier. The composite material containing a tackifier is a synthetic high polymer material that can A composite material synthesized from powder particles that increase the adhesion coefficient between the wheel pair and the rail. The tackifier block contains at least adhesive and adhesion coefficient improver. The adhesive and the adhesion coefficient improver are mixed in a mixer according to the ratio, and a solid block with a certain hardness is formed by synthesis, that is, a thickening block. The present invention makes a thickening block of composite material, installs it next to the wheel, and coats the thickening substance on the rolling surface of the wheel to change the adhesion coefficient between the wheel pair and the rail, thereby suppressing and preventing idling.

Description

technical field [0001] The invention relates to a device for preventing rail vehicle wheels and rails from slipping and a method for making and using the same, in particular to a device for increasing the adhesion and traction between wheels of rail vehicles and rails and methods for making and using the device. The device can replace locomotive sanding to increase the adhesion traction between the rail vehicle wheel set and the steel 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 conta...

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 sanding 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. The roadbed caused by sanding The cost of pollution treatment is high

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