Abstract

A kind of coal mine explosion-proof vehicle pneumatics; two the five-way control cock comprising brake control valve group, transmission disconnecting valve, braking during standstill control cock, gas starter motor, the shutdown cylinder connected with electrical generator and connect with source of the gas; two five-way control cock are provided with spring automatic reset mouth and working hole; the spring automatic reset mouth of two five-way control cock is connected with shutdown cylinder by pipeline, and the working hole of two five-way control cock is connected with two-bit triplet control cock by pipeline.The utility model is when two five-way control cock are in working hole, and driving engine can start, and two-bit triplet control cock possesses service conditions, and brake control valve group has running braking function; When two-bit triplet control cock is in control position, starts control cock and lost efficacy, achieve automatic parking brake of dying, achieve driving engine No Load Start, improve production efficiency.

Description

A kind of coal mine explosion-proof vehicle pneumatics
Technical field
The utility model relates to a kind of vehicular pneumatic systems, particularly a kind of coal mine explosion-proof vehicle pneumatics.
Background technology
Traditional coal mine explosion-proof vehicle pneumatics is not died and is automatically realized braking during standstill, engine starting cannot realize No Load Start automatically, once forget that braking during standstill easily causes potential safety hazard, in addition, driving engine, when starting, due to comparatively heavy load, causes difficulty in starting, have impact on normal coal production operation, reduce production efficiency.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, proposes a kind of safe and reliable, the coal mine explosion-proof vehicle pneumatics of can realize dying automatic parking brake and driving engine No Load Start.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of coal mine explosion-proof vehicle pneumatics, comprise brake control valve group, transmission disconnecting valve, braking during standstill control cock, gas starter motor, the shutdown cylinder connected with electrical generator and two the five-way control cock connected with source of the gas, be characterized in: two five-way control cock are provided with spring automatic reset mouth and working hole, the spring automatic reset mouth of two five-way control cock is connected with shutdown cylinder by pipeline, the working hole of two five-way control cock is connected with two-bit triplet control cock by pipeline, two-bit triplet control cock is provided with air extractor duct, air extractor duct is connected with transmission disconnecting valve by branched pipe I, air extractor duct is connected with braking during standstill control cock by branched pipe II, air extractor duct is connected with gas starter motor by branched pipe III, branched pipe III is provided with Pneumatic valve, Pneumatic valve is provided with low pressure port and high-pressure mouth, the low pressure port of described Pneumatic valve connects with gas starter motor, the high-pressure mouth of Pneumatic valve is connected with brake control valve group by connecting line, the pipeline that Pneumatic valve connects with gas starter motor is provided with startup control cock.
Compared with prior art, the utility model is when being communicated with source of the gas, and the spring automatic reset mouth of two five-way control cock communicates with shutdown cylinder, makes driving engine be in stopped status; When two five-way control cock are in working hole, driving engine can start, and two-bit triplet control cock possesses service conditions, and start control cock simultaneously and start, brake control valve group has running braking function; When two-bit triplet control cock is in control position, its outlet starts to have pressure, now start control cock to lose efficacy, transmission disconnecting valve makes speed regulation device out of supply, braking during standstill control cock group brake off, achieves automatic parking brake of dying, and avoids and forgets braking during standstill and the potential safety hazard caused, achieve driving engine No Load Start, improve production efficiency.
Accompanying drawing explanation
Fig. 1 is hydraulic schematic diagram of the present utility model.
Detailed description of the invention
A kind of coal mine explosion-proof vehicle pneumatics, comprise brake control valve group, transmission disconnecting valve, braking during standstill control cock, gas starter motor, the shutdown cylinder connected with electrical generator and two the five-way control cock 1 connected with source of the gas, two five-way control cock 1 are provided with spring automatic reset mouth and working hole, the spring automatic reset mouth of two five-way control cock 1 is connected with shutdown cylinder by pipeline, the working hole of two five-way control cock 1 is connected with two-bit triplet control cock 2 by pipeline, two-bit triplet control cock 2 is provided with air extractor duct, air extractor duct is connected with transmission disconnecting valve by branched pipe I, air extractor duct is connected with braking during standstill control cock by branched pipe II, air extractor duct is connected with gas starter motor by branched pipe III, branched pipe III is provided with Pneumatic valve 3, Pneumatic valve 3 is provided with low pressure port and high-pressure mouth, the low pressure port of described Pneumatic valve 3 connects with gas starter motor, the high-pressure mouth of Pneumatic valve 3 is connected with brake control valve group by connecting line, the pipeline that Pneumatic valve connects with gas starter motor is provided with and starts control cock 4.
With reference to accompanying drawing 1, when system starts to provide source of the gas, two five-way control cock are in a state and are namely in spring automatic reset mouth place, and make shutdown cylinder action, driving engine is in stopped status; When two five-way control cock are in b state, driving engine can start, and the two-bit triplet control cock of spring automatic reset possesses service conditions, and meanwhile, starting control cock can start, and brake control valve group has running braking function; When the two-bit triplet control cock of spring automatic reset is in a state, its (3) mouth is without pressure, now Pneumatic valve is in a state, its (3) mouth has pressure, start control cock effective, can start, and (3) mouth of the two-bit triplet control cock of spring automatic reset is without pressure, transmission disconnecting valve can be made to be in state out of supply, braking during standstill control cock group brake off; When the two-bit triplet control cock of spring automatic reset is in b state, its (3) mouth has pressure, Pneumatic valve can be made to be in b state, (3) mouth of Pneumatic valve is without pressure, start control cock to lose efficacy, the pressure of (3) mouth of the two-bit triplet control cock of spring automatic reset can make transmission disconnecting valve be in non-state out of supply simultaneously, and braking during standstill control cock group is in brake off state, can drive a vehicle.
So, the two-bit triplet control cock of spring automatic reset must be in a state, thus make transmission disconnecting valve be in state out of supply, make braking during standstill control cock group be in braking during standstill state, startup control cock could be allowed to work, realize neutral and start.In addition, when system stops air feed, the two-bit triplet control cock of spring automatic reset can automatically reset, and is in a state, namely braking during standstill state, and out of supply.
