Safety brake device for loading of mine dumper with motor-driven wheels

Abstract

A safety brake device for loading of a mine dumper with motor-driven wheels is characterized in that two signal output ends of a two wire switch are electrically connected with the on-off input end of a controller. The controller is a self special controller for the mine dumper with motor-driven wheels, the on-off output end of the controller is simultaneously electrically connected with one ends of two identical electromagnetic valves and a cathode of a fly wheel diode, and the other ends of the two electromagnetic valves are simultaneously electrically connected with an anode of the fly wheel diode and connected with the ground. The safety brake device has the advantages of being capable of achieving the loading brake function, good in brake effect, safe and reliable.

Description

[0001] technical field [0002] The invention relates to an electric-wheel mining dump truck, in particular to a loading safety brake device for an electric-wheel mining dump truck, and belongs to the technical field of an electric-wheel mining dump truck. Background technique [0003] The electric wheel mining dump truck is the main tool for mineral transportation. The working environment of the electric wheel mining dump truck is generally: the time for loading goods is generally short, but the impact force of the goods on the electric wheel mine dump truck is relatively large when loading the goods. Therefore, during the working process, the driver generally does not need to turn off the engine, and at the same time brakes through the pedal brake system set by the electric wheel mining dump truck itself to prevent the impact of cargo loading from causing electric shock. The displacement of the mine dump truck and other safety accidents caused by it. Obviously, the foot ...

Problems solved by technology

[0003] The electric wheel mining dump truck is the main tool for mineral transportation. The working environment of the electric wheel mining dump truck is generally: the loading time is generally short, but the loading The goods have a greater impact on the electric-wheel mining dump truck during the cargo process. Therefore, during the work process, the driver generally does not need to turn off the engine, and at the same time use the pedal brake set by the electric-wheel mining dump truck itself. The system performs braking to prevent the displacement of the electric wheel mining dump truck caused by the impact of cargo loading, and other safety accidents caused by it. Obviously, a long time of pedal braking is likely to cause driver fatigue , coupled with the influence of human factors, it is easy to cause unreliable braking, and thus lead to corresponding safety accidents

Although in the prior art, corresponding improvements are made for the above-mentioned defects of the electric wheel mining dump truck, for example: Chinese Patent No. 201120172879.X patent name is "loading brake system device for electric wheel mine dump truck", This patented technology solves the defects of the pedal brake by setting a set of independent automatic devices composed of switches, controllers, solenoid valves, and freewheeling diodes. Working in a harsh environment with many impacts, easy to damage and unreliable work, once the above situation occurs, it will inevitably lead to corresponding safety accidents
