Abstract

The invention discloses a braking method of a gear rail car, On the basis of adhering a brake device to the belt brake device, the gear rail car first receives a the brake command, the ground gradientof the line running on the gear-rail car is acquired first, the line is the gear-rail line is judged according to the ground gradient, if it is, the adhesive brake and the belt brake are started, ifnot, the adhesive brake is started. In the prior art, the braking mode of the gear-rail car is only adhesive braking, and the braking mode cannot meet the braking requirements when the gear-rail car is traveling on the ramp. The invention adopts the combination of adhesive braking and belt braking on the gear track to complete the braking. The belt braking is more suitable for ramp braking than adhesive braking, and the gear track car can reach the braking requirement on the ramp. The braking mode is selected by the ground slope of the running track, so that the gear-rail car can meet the braking requirements both on the straight road and on the ramp. The invention also discloses a braking device of a gear rail car, which has the beneficial effects.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a braking method and a braking device for a rack car. Background technique [0002] The rack car is mostly used in the mine system for the transportation of coal and ore in the mine. Because the slope of the transportation channel is generally relatively gentle, the braking control system of the rack car usually only considers the operation of the straight road. However, in some special environments, the rack car also needs to run on the ramp. When the rack car is running on a slope, due to the effect of gravity, the previous braking method will not be able to meet the requirements of emergency braking distance and other indicators, which may cause safety accidents. [0003] Therefore, how to make the braking control of the rack car adapt to the braking of the rack car on different types of lines, so as to meet the braking requirements of the rack car and ensure the safe oper...
