Abstract
The utility model provides a brake release device's automatic control system, including program controller, be equipped with pressure sensor on the power that is connected with program controller, be equipped with the brake and remove the switch, the brake is removed switch one end and is linked to each other with program controller, and the other end links to each other with the power, and the power links to each other with fuse and battery, is equipped with the solenoid valve on the negative pole that is connected with program controller, is equipped with the electric pump, and electric pump one end links to each other with program controller, links to each other with the power simultaneously, and the solenoid valve all links to each other with battery circuit with the electric. The utility model discloses realize automated control, reduction personnel's that can be great intensity of labour improves work efficiency greatly, and the driver only needs to press the braking and removes the button, alright open with the axle stopper with quick, has also ensured simultaneously that hydraulic system pressure is unlikely to too high to arouse hydraulic system overload damage sealed.
Description
Technical Field
The utility model belongs to the technical field of mining equipment, specifically speaking relates to an automatic control system of brake release device.
Background
At present, a brake release device of underground mine trackless equipment mainly adopts manual operation, a ball valve is closed to cut off a pipeline of an original brake hydraulic system, a manual pump is used for pressing brake oil into an axle brake, and a brake spring is jacked open to open a bridge. The method is time-consuming and labor-consuming, can not ensure the constant pressure in the axle in real time, can not monitor the pressure in real time, and still needs manual pressing after the pressure is reduced. If pressure is not enough and the discovery is not timely, wear out the axle brake very easily, arouse stopper high temperature, sealed ageing scheduling problem, shorten the life of axle greatly.
SUMMERY OF THE UTILITY MODEL
The utility model provides an automatic control system of brake relieving device has solved the artifical manually operation brake relieving device among the background art and has wasted time and energy, the unable shortcoming of guaranteeing of pressure.
The technical scheme of the utility model is realized like this: the automatic control system of the brake release device comprises a program controller, wherein a pressure sensor and a brake release switch are arranged on a power supply connected with the program controller, one end of the brake release switch is connected with the program controller, the other end of the brake release switch is connected with the power supply, the power supply is connected with a fuse and a storage battery, an electromagnetic valve and an electric pump are arranged on a negative electrode connected with the program controller, one end of the electric pump is connected with the program controller and is simultaneously connected with a power supply A, and the electromagnetic valve and the electric pump are both connected with a storage battery circuit.
The utility model has the advantages that: the utility model discloses realize automated control, reduction personnel's that can be great intensity of labour, improve work efficiency greatly, the driver only needs to press the braking and removes the button, alright open axle brake with quick, and program controller real-time detection axle brake pressure, maintain axle brake's opening pressure at a stable effectual within range all the time, pressure sensor has ensured that axle brake opens completely, prevent the damage of axle, it is unlikely to too high hydraulic system pressure to arouse hydraulic system overload damage sealed also to have ensured simultaneously.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Description of the parts: 1. the device comprises a program controller 2, a pressure sensor 3, an electromagnetic valve 4, an electric pump 5, a brake release switch 6, a fuse 7, a storage battery 8, a power supply 9 and a negative electrode.
Detailed Description
For a better understanding and appreciation of the invention, it will be further described in connection with the accompanying drawings: an automatic control system of a brake release device comprises a program controller 1, a pressure sensor 2 is arranged on a power supply 8 connected with the program controller 1, a brake release switch 5 is arranged, one end of the brake release switch 5 is connected with the program controller 1, the other end of the brake release switch is connected with the power supply 8, the power supply 8 is connected with a fuse 6 and a storage battery 7, an electromagnetic valve 3 is arranged on a negative electrode 9 connected with the program controller 1 and is provided with an electric pump 4, one end of the electric pump 4 is connected with the program controller 1 and is simultaneously connected with the power supply 8, and the electromagnetic valve 3 and the electric pump 4 are both connected with the storage battery 7 through circuits.
When the equipment has serious faults and the engine cannot be started, after the brake release switch 5 is pressed down, the electromagnetic valve 3 is electrified, the brake oil path is switched on, the program controller 1 collects pressure signals of the pressure sensor 2, when the pressure is lower than 120bar, the electric pump 4 is controlled to work, and when the pressure reaches 140bar, the electric pump 4 is automatically stopped, so that the front axle brake and the rear axle brake are opened, and external force can be applied to drag the equipment.
