Dynamic Analysis Of Rubber-tyred Vehicle Safety Protection Device

Underground transportation is an important part of the work of coal mine production process, the application of anti running system in underground coal mine is mainly on the inclined lane lifting rail winch, a protection system for inclined lane car bumper and car arrester. Whether it is car or car arrester are passi ve to stop stalling and transport vehicles, two kinds of block mode is n ot suitable for underground trackless tyred vehicle stop. According to the design of a kin d of rubber tyred vehicle safety stop device in inclined roadway of trackless rubber tyred vehicle in well oblique lane transport stall phenomenon, has an important significance to prevent underground rubber tyred vehicle stall.In this paper a rubber tyred vehicle safety stop device design of coal mine oblique lane transport rubber tire vehicle stall phenomenon, through the field test data show that the blocking mechanism is reasonable, the stopping device can reduce the initial braking moment of impact, and can in a short distance will stall vehicle b raking; dynamic characteristics of wire rope stop mechanism under impact load; to establish the three-dimensional model of brake block mechanism and a buffer, buffer analysis of three-dimensional model of brake and mechanical properties of the brake when t he vehicle safety protection device based on the block, analysis results show that with the increase in the braking distance, braking force stop device increases rapidly.This paper analyzes the theoretical calculation and practical application of the diameter of wire rope calculation of gap, and m ain factors affecting the steel wire rope diameter selection, gives the formula calculating the diameter of wire rope with rubber tyred vehicle safety stop device, convenient for reasonable selection of wire rope use coefficient of wire rope diameter.
