10 with pressure oil branch roadDelay acoustic-optic alarm is provided between 4, delay acoustic-optic alarm is by normally closed flame-proof mine pressure
Switch 5, normally opened flame-proof mine pressure switch 9 and flame-proof mine voice audible-visual annunciator 7 are composed in series, described normally opened mining
The control port of flame-proof type pressure switch 9 and pressure oil branch roadIt is connected, the control port of normally closed flame-proof mine pressure switch 5
With pressure oil branch roadIt is connected, accumulator 8 is provided with guide's oil return line between sequence valve and adjustable throttling；Work as guide oil
When the pressure oil inlet that loop associates with parking has pressure, pressure is by pressure oil branch roadOpened into normally opened flame-proof mine pressure
Close, make its closure, flame-proof mine voice audible-visual annunciator obtains electric, flame-proof mine voice audible-visual annunciator work, while liquid
Force feed passes through adjustable throttling, and into accumulator, sequence valve commutates when pressure reaches 20bar in accumulator, and pressure is by pressure oil
Branch roadInto normally closed flame-proof mine pressure switch, make its disconnection, the power-off of flame-proof mine voice audible-visual annunciator stops work
Make, meanwhile, pressure oil enters the control oil pocket of pilot operated directional control valve, pilot operated directional control valve commutation, and guide oil, which is connected, causes walking variable
Pump variable, vehicle are normally started to walk；When the pressure oil inlet pressure that guide oil loop associates with parking disappears, inside accumulator
Pressure oil is commutated by the rapid oil return box of check valve, pressure zero, sequence valve, and the pressure oil in pilot operated directional control valve control chamber is through suitable
Sequence valve oil return box, pilot operated directional control valve reset, and pilot control cut-out starts delay alarming device and restPosed.Its master of the present invention
It is vehicle launch alarm and the delayed startup for realizing vehicle to act on, and operation principle is delays time to control row after vehicle releases braking
Variable pump guide's fuel feeding is walked, so as to control the delayed startup of vehicle, flame-proof mine voice acousto-optic report is controlled during delay
Alert device is propagandaed directed to communicate, and realizes vehicle launch alarm and the delayed startup function of vehicle.
The guide oil branch road to connect with pilot control is additionally provided with the oil-out in guide oil loop, on guide oil branch road
The control ball valve 2 of manual ON pilot control when being failed provided with start-up study acoustic-optic alarm.Installed on guide oil branch road
There is the pressure gauge 1 of display pilot control oil pressure.Pressure gauge 1 is used to show guide's oil pressure, prompts whether driver's guide's oil circuit connects
It is logical.The drain tap to connect by drain line with fuel tank is additionally provided with sequence valve.Installed in the pressure oil entrance of sequence valve
There is the sequence valve pressure measuring tie-in 14 of testing sequence valve input pressure, sequence valve pressure measuring tie-in 14 is used for testing sequence valve oil inlet pressure
Power.Parking braking oil pressure measuring tie-in 13 is installed in the pressure oil entrance of flow regulating valve, parking braking oil pressure measuring tie-in 13 is used
In measurement parking system pressure.The adjustable throttling is also parallel with check valve 11, the oil inlet end and adjustable throttling of check valve
Pressure oil export be connected, the oil outlet end of check valve 11 is connected with the pressure oil inlet of adjustable throttling.To ensure safety, colliery
Underground vehicle is forced to brake using fail safe type, i.e. spring braking, and hydraulic pressure releases.When that is having pressure oil at F in figure
Vehicle parking releases, it is allowed to starts traveling.Vehicle parking during no pressure oil, can not start at F.Meanwhile vehicle is
Hydraulic drive vehicle, the power of vehicle launch traveling are provided by 2 walking variable pumps, only control walking variable pumpage
Guide's oil return line has oil pressure, and variable pump variable of walking, driver steps on the gas, and vehicle hydraulic running gear can just provide dynamic for vehicle
Power.Vehicle just can normally start to walk, and the present invention utilizes EPB pressure, and delays time to control hydraulic moving variable pump guide oil returns
The break-make on road realizes delayed startup, while passes through normally closed flame-proof mine pressure switch and normally opened mine explosion-suppression during delay
Type pressure switch controls the start and stop of flame-proof mine voice audible-visual annunciator.Concrete operating principle is as follows：Work as parking braking system
When having pressure（When i.e. driver's take-off the brake handle prepares to start vehicle）, pressure enters normally opened flame-proof mine pressure switch,
Make its closure, flame-proof mine voice audible-visual annunciator obtains electric, and alarm flicker repeats to propaganda directed to communicate " vehicle launch, to note simultaneously
Meaning ".Hydraulic oil is by adjustable throttling simultaneously, and into accumulator, pressure is gradually increasing in accumulator, when pressure reaches 20bar
When sequence valve commutate, normally closed flame-proof mine pressure switch makes it disconnected while pressure oil enters pilot operated directional control valve control oil pocket
Open, the power-off of flame-proof mine voice audible-visual annunciator, stopping of propagandaing directed to communicate.Meanwhile pressure oil quickly enters pilot operated directional control valve control oil
Chamber, pilot operated directional control valve commutation, guide oil are connected, and hydraulic moving pump variable, driver steps on the gas, variable pump pressure oil output, car
Just can normally it start to walk.Vehicle is delayed and flame-proof mine voice audible-visual annunciator propagandas directed to communicate the time by adjustable throttling and accumulator
Co- controlling, flame-proof mine voice audible-visual annunciator are propagandaed directed to communicate before stopping, even if driver unclamps parking brake, having been stepped on the gas by force
Step, because hydraulic moving variable pump pilot control is off, vehicle can not still start to walk, when only reaching the delay of setting
Between, flame-proof mine voice audible-visual annunciator propaganda directed to communicate stop vehicle just allowing to start to walk, effectively prevent driver's failure to inspect, police
Show, irritable the problem of causing vehicle-surroundings casualties of driving a vehicle.When parking braking system distress resolves（I.e. driver's pull-up is braked
Handle, when vehicle is braked）, pressure oil inside accumulator is by the rapid oil return box of check valve, pressure zero, sequence valve commutation,
Pressure oil in pilot operated directional control valve control chamber resets through sequence valve oil return box, pilot operated directional control valve, pilot control cut-out start-up study
Acoustic-optic alarm restPoses.Control ball valve when start-up study acoustic-optic alarm breaks down can manual unlocking,
Pilot control is connected and ensures that vehicle is normally walked.
