Description
Technical field
The utility model relates to the anti-slip control system of electric wheel mining truck, belongs to the haul truck field of intelligent control.
Background technology
The electric wheel mining truck is a kind of large-scale transportation device, has that load carrying ability is large, efficient is high, traffic cost is low and the characteristics such as long service life.Along with open cast mine to large scale development, the mine user is more and more, also more and more higher to the requirement of electric wheel mining truck simultaneously to the demand of Large Electric wheel mine truck.Especially, the safety of electric wheel mining truck is had higher requirement.Through investigation, the moving accident that causes happens occasionally surface mine owing to the electric wheel mining truck slips, the electric wheel mining truck heavy duty weight of using on the mine at present is all more than 400 tons, if so the moving phenomenon of large-tonnage electric wheel mining truck generation slide is breakneck.So the mine user requiring consumingly main engine plants to solve the moving problem of slide of truck, realizes automatic anti-running, the generation of Accident prevention.
Summary of the invention
The purpose of this utility model is to provide a kind of electric wheel mining truck anti-slip control system, and this system avoids the generation of the moving phenomenon of slide of electric wheel mining truck, has improved safety performance.
Technical solution:
The utility model comprises wheel motor drive system, control system, brake system and gearshift finder.The wheel motor drive system comprises: wheel motor motor, speed sensor, and the speed sensor input end is connected with the wheel motor motor;
Control system comprises: speed comparator, direction comparator and forward controller, the speed sensor mouth is connected respectively to the input end of speed comparator and direction comparator, speed comparator is connected mouth and is connected with the input end of forward controller respectively with the direction comparator, the mouth of forward controller is connected to the input end of the braking electromagnetic valve of brake system;
The input end of direction comparator also is connected with the mouth of gearshift finder simultaneously.
Direction comparator Real-time Collection is from the electric wheel mining truck shift signal of the gearshift finder that sends of gearshift finder and transmit the velocity reversal signal of the wheel motor motor of returning from speed sensor, and carry out Boolean calculation, again operation result is sent to forward controller.
The speed comparator Real-time Collection transmits the velocity magnitude signal of the wheel motor motor of returning from speed sensor, and carries out Boolean calculation, again operation result is sent to forward controller.
The Boolean calculation result of forward controller Real-time Collection direction comparator and speed comparator, if the result satisfies the moving condition of slide then controls braking electromagnetic valve the electric wheel mining truck is braked, so that brake caliper is embraced brake disc, prevent that strictly the slide of electric wheel mining truck is moving.
The utility model is to have configured speed sensor, speed comparator, forward controller, direction comparator for electric wheel mining truck control system.Velocity magnitude and the direction of electric wheel mining truck speed sensor Real-time Collection wheel motor motor, and respectively the result is sent to speed comparator and direction comparator; Speed comparator is responsible for if satisfy the moving condition of slipping, then the result being sent to forward controller to slipping the comparison of velocity magnitude; The value of direction comparator Real-time Collection speed sensor and gearshift finder is if both contradictions then send to forward controller with the result; The result of forward controller Real-time Collection speed comparator and direction comparator, moving condition is satisfied when slipping, and then removes to control braking electromagnetic valve, and drg is embraced, and strictly realizes electric wheel mining truck automatic anti-running, prevents that contingency from occuring.
Description of drawings
Accompanying drawing 1 is the utility model schematic diagram;
Accompanying drawing 2 is the utility model schematic diagram.
The specific embodiment
As shown in Figure 1, this system is comprised of wheel motor drive system 1, control system 2, brake system 3 and gearshift finder 4.Wherein wheel motor drive system 1 comprises: wheel motor motor 6, speed sensor 5; Control system 2 comprises: speed comparator 7, direction comparator 9 and forward controller 8; Brake system 3 comprises: braking electromagnetic valve 10 is installed on the brake piping.The input end of speed sensor 5 is connected with the mouth of wheel motor motor 6, and its mouth is connected respectively to speed comparator 7 and direction comparator 9; The input end of direction comparator 9 also is connected with the mouth of gearshift finder 4 simultaneously; The input end of forward controller 8 is connected with the mouth that speed comparator 7 is connected with the direction comparator respectively; The mouth of forward controller 8 is connected to the input end of the braking electromagnetic valve 10 of brake system 3.
Direction comparator 9 Real-time Collections are from the gearshift electric wheel mining truck shift signal that sends of finder 4 and transmit the velocity reversal signal of the wheel motor motor 6 of returning from speed sensor 5, and carry out Boolean calculation, again operation result is sent to forward controller 8; Moving speed in the slide of forward controller 8 interior setting electric wheel mining trucies is 0.8km/h, the speed comparator 7 Real-time Collections wheel motor motor that 5 transmission are returned from speed sensor) velocity magnitude signal, and carry out Boolean calculation, again operation result is sent to forward controller 8; The Boolean calculation result of forward controller 8 Real-time Collection direction comparators 9 and speed comparator 7, if the result satisfies the moving condition of slide then controls 10 pairs of electric wheel mining trucies of braking electromagnetic valve and brake, so that brake caliper is embraced brake disc, prevent that strictly the slide of electric wheel mining truck is moving.
As shown in Figure 2, according to the running condition of electric wheel mining vehicle, precision characteristic and the actual condition of sensor, strictly prevent maloperation, definition only has the moving speed of the slide of working as just to carry out associative operation greater than the 0.8km/h Time Controller.If defining following several situation occurs then thinks that electric wheel mining vehicle is slipping car:
(a) when chaufeur is hung forward gear, the velocity reversal of the electric wheel mining vehicle that wheel motor speed sensor 5 records is for backward, and slide vehicle speed＞0.8km/h;
(b) hang when falling back gear when chaufeur, the velocity reversal of the electric wheel mining vehicle that wheel motor speed sensor 5 records is for forward, and slide vehicle speed＞0.8km/h;
(c) when chaufeur was hung neutral, the velocity amplitude of the electric wheel mining vehicle that wheel motor speed sensor 5 measures was non-vanishing, and slide vehicle speed＞0.8km/h.
When the moving condition of slide satisfied, forward controller 8 went to control braking electromagnetic valve 10 work of brake system immediately, and drg is embraced, and strictly realizes electric wheel mining truck automatic anti-running, prevents that contingency from occuring.
