Abstract

The utility model discloses a vapour -pressure type electrical mining locomotive braking control device, on its prior art's basis, this arresting gear comprises parts such as air compressor, oil water separator, gas holder, brake pedal, brake control valve, solenoid valve, pressure regulating unit, brake chamber, the fast sensors of wheel. It is convenient for considering brake force size and repacking, install the stopper at the reduction gear fast axis and adopt disc brake. The brake pedal conduct triggers the break -make that mechanism controls the air supply, and then is controlling brake chamber's the action of exitting of filling, finally reaches the purpose of damper operator braking torque. Vapour -pressure type arresting gear operates lightly, provides big braking moment, responds advantages such as fast. The problem of among prior art troublesome poeration, length consuming time, the empty trip distance of locomotive is long and locking wheel phenomenon etc. Appears down in emergency easily is solved.

Description

A kind of vapour-pressure type mining electric locomotive brake control
Technical field
The present invention relates to a kind of brake control, is exactly a kind of vapour-pressure type mining electric locomotive brake control.
Background technology
Coal is the main fossil energy of China, and very big proportion is occupied in the energy resource consumption of China.Therefore, coal Industry also just becomes the foundation stone of China's energy industry naturally.Mining electric locomotive is mainly used in the length on the big lane of underground transportation and ground Distance transport.Mining electric locomotive draws the train being made up of mine car or people's car equivalent to the electric locomotive head in railway transportation Walking in orbit.Complete to coal, spoil, material, equipment, personnel transport.Therefore, mining electric locomotive is transported in coal master With very important role is all play in assistant conveyance.
The large and small skilful flexible, simple structure of mining electric locomotive pull strength, maintenance cost are low, and using driven by power, pollution is few.
In prior art, the more extensive mining electric locomotive brake unit of application is handwheel brake shoe formula brake unit, is logical Crossing driver's rotation handle causes the gimbal lever to move, and then drives a series of link motion, and most at last active force is applied to brake shoe On, control the rotating speed of wheel.It is a kind of adhesion braking.The structure is relatively simple, low cost.But there is also it is many not Foot, be mainly manifested in it is following some:
(1) circle of driver's both hands rotation hand wheel 3 left and right is needed to implement to brake in braking, troublesome poeration, time-consuming, About 2~5 seconds, this will cause locomotive idle stroke distance;
(2) brake force is applied on handwheel by handss, and brake force is limited, and wayward, in emergency circumstances easily occurs embracing Dead phenomenon, causes the relative slip of wheel track, braking friction drastically to decline;
(3) in case of emergency, driver is often forced to take reversing braking.Joint burns out, motor is received to cause commutation The accidents such as damage, speed reduction gear box fracture;
(4) single shoe brake mode is belonged to., to side stress, axle box force-bearing situation is poor, easily makes bearing inclined for braking hour wheel Difference:
(5) typical linkage, its processing, rigging error and elastic deformation can all cause brake shoe unbalance stress, lead Cause brake shoe partial wear.
The content of the invention
It is an object of the present invention to provide a kind of simple to operate, fast response time and being capable of a kind of vapour-pressure type ore deposit of anti-lock Electricity consumption locomotive braking control device.
The technical scheme that the present invention is adopted for achieving the above object is that a kind of vapour-pressure type mining electric locomotive control for brake is filled Put, it is characterised in that including air compressor, oil water separator, air accumulator, brake pedal, brake control valve, electromagnetic valve, system Take offence room, brake, wheel speed sensors, pressure regulating unit.
The brake uses disk brake, is made up of brake disc and caliper.To consider its brake force and changing Dress is convenient, is installed in high-speed shaft of speed reducer.
Two brake discs are adopted in electric locomotive, is separately mounted on two sets of running mechanisms, there are two systems in each brake disc Dynamic pincers composition.Braking branch respectively controls a brake disc using each loop.
What above-mentioned technical proposal was directly brought has the technical effect that:On the one hand, improve original brake unit response speed, Time-consuming, troublesome poeration the problems such as.
On the other hand, the brake unit controls the size of source of the gas by brake pedal, and by pressure regulating unit control The inflation/deflation action of brake chamber, the size of air pressure is controlled, the purpose of regulating brake braking torque is finally reached, is solved Locking wheel easily occurs in brake hard in original brake unit causes the relative sliding problem of wheel track.
What the technical scheme was directly brought has the technical effect that, simple to operate during braking, fast response time, and according to its motion The pressure of status adjustment wheel cylinder, the braking moment of regulating brake prevents wheel lock up, and the creep rate of wheel is maintained at most Near good nodulizing rate, wheel rail adhesion coefficient utilization rate or ground attaching coefficient are greatly enhanced, and then reduce braking distance, strengthened The reliable degree of vehicle traveling.
Description of the drawings
Fig. 1 is air-pressure brake antilock system diagram
Fig. 2 is brake disc schematic view of the mounting position
Description of the drawings:1. pressure regulating unit, 2. electromagnetic valve, 3. brake chamber, 4. wheel speed sensors, 5. brake, 6. Air compressor, 7. oil water separator, 8. air accumulator, 9. brake pedal, 10. brake control valve.
Specific embodiment
Below in conjunction with the accompanying drawings, the present invention is elaborated.
As shown in Figures 1 and 2, a kind of vapour-pressure type mining electric locomotive brake control of the invention, it is characterised in that Including pressure control unit 1, electromagnetic valve 2, brake chamber 3, wheel speed sensors 4, brake 5, air compressor 6, oil-water separation Device 7, air accumulator 8, brake pedal 9, brake control valve 10.
The brake force of the system is provided by pneumatic supply 6, and brake pedal 9 controls brake control valve as trigger mechanism, by Brake control valve controls the air pressure into brake chamber.The rate signal for measuring is delivered to pressure and adjusts single by wheel speed sensors 4 Unit 1, and then the action of electromagnetic valve 2 is controlled, the inflation/deflation action of brake chamber 3 is realized, by the way that supercharging-pressurize-reducing pressure, this is followed Gyration is made, and is finally reached the purpose of the braking torque of regulating brake 5, to ensure that wheel fluctuates to creep rate near optimum, enters And provide bigger brake force for electric locomotive.
Certainly, described above is not that, to restriction of the present utility model, this utility model is also not limited to the example above, Change, remodeling, addition or replacement that those skilled in the art are made in essential scope of the present utility model, also should Belong to protection domain of the present utility model.
