Method for limiting and protecting wheel sets of 10m<3> underground mine cars

Abstract

The invention relates to the field of technologies for limiting and protecting wheel sets of mine cars, in particular to a method for limiting and protecting wheel sets of 10m<3> underground mine cars. The method includes measuring the width-side distances from wheel flanges of the wheel sets of the mine cars to main girders at the bottoms of the mine cars to determine the widths of steel plates; abrading harmful substances by the aid of polishing machines; respectively welding the steel plates at certain positions of front groups of wheel sets and certain positions of rear groups of wheel sets. The certain positions of the front groups of wheel sets are flush with the main girders, and the certain positions of the rear groups of wheel sets are flushed with front main girders. The method has the advantages that road falling frequencies of the wheel sets of the 10m<3> mine cars at ore discharge stations can be effectively controlled after tempering heat-insulation is carried out, the flanges of the wheel sets instantly rub with the edges of the steel plates when the wheel sets are collided with steel rails and are reset, large-amplitude twisting spaces of the wheel sets can be controlled, accordingly, the mine cars can stably run, and stable and high yield purposes of enterprises can be assuredly achieved.

Description

technical field [0001] The invention relates to the technical field of position-limiting protection of a mine wheel pair, in particular to a method for position-limiting protection of an underground 10m3 mine wheel pair. Background technique [0002] The main purpose of the underground mine car is to transport ore at the -420 level. After each ore drawing, when the 10m3 mine car is unloading at the -420 level ore unloading station, the wheels will collide when they pass the main rail and the auxiliary rail. The steel rails have a strong impact, and it is difficult for the driver to control the speed of the vehicle. He violently increases the gear of the operating handle, causing the wheel set's rim to straddle the steel rail, causing the wheel set to always fall off the road at the exit of the ore unloading station. At this time, the operator needs to restore the wheel set to the rail, which seriously wastes the working time and the physical exertion of the personnel. Cont...

[0002] The main purpose of the underground mine car is to transport ore at the -420 level. After each ore drawing, when the 10m3 mine car is unloading at the -420 level ore unloading station, the wheels will collide when they pass the main rail and the auxiliary rail. Steel rails, the impact force is relatively large, it is difficult for the driver to control the speed of the vehicle, and the gear of the operating handle is violently increased, causing the wheel set wheel flange to ride on the steel track, causing the wheel set to always fall off the road at the exit of the unloading station

At this time, the operator needs to restore the wheel set to the rail, which seriously wastes the working time and the physical exertion of the personnel.
