Fig. 2 is the utility model electrical schematic diagram.
The specific embodiment
Embodiment 1
As shown in Figure 2, the utility model is installed in the operator's compartment, comprise the 1st intermediate relay Q1 and the 2nd intermediate relay Q2, wherein coil one termination of the 2nd intermediate relay Q2 is from the power takeoff power supply, the other end links to each other with brake ground signalling line, and the open contact J2 of the 2nd intermediate relay Q2 and power take-off valve K1 are connected in series on the power lead of vehicle-mounted emergent computer; Coil one end of the 1st intermediate relay Q1 is connected to the power takeoff power supply through the open contact J2 of power take-off valve K1 and the 2nd intermediate relay Q2, the other end links to each other with the brake ground signalling, and the open contact J1 of the 1st intermediate relay Q1 and vehicle-mounted emergent computer switch K2 are series on the power lead of vehicle-mounted emergent computer.Side near vehicle-mounted emergent computer on vehicle-mounted emergent computer power line is provided with emergent computer indicator lamp D2; Side near the power takeoff electromagnetic valve on the power takeoff power lead is provided with power of electromagnetic valve indicator lamp D1.
Principle of work of the present utility model is:
Vehicle could be given stopping brake lock when neutral gear, parking, the brake ground signalling is arranged this moment, the 2nd intermediate relay Q2 coil is charged, then its open contact J2 closure, closed power take-off valve at this moment, then the power takeoff coil is charged, the work of driving power takeoff, the 1st intermediate relay Q1 coil is charged simultaneously, and it is located at the open contact closure on the vehicle-mounted emergent computer power line, this moment is with vehicle-mounted emergent computer switch K2 closure, then vehicle-mounted emergent computer work.
Present embodiment is example with the dumping car.When dumping car stops, after the execution self-unloading finishes, need during normal running Hydraulic Pump is stopped, get back to the wagon box original position, dumping car just can travel, if violate this operating instruction, forgets and closes the Hydraulic Pump switch, be that power take-off valve K1 and vehicle-mounted emergent computer switch K2 disconnect, the wagon box of the vehicle behind installation the utility model can be got back to original position automatically, and stopping brake lock unclamps, and the stopping brake lock ground signalling is arranged, vehicle can travel, then deny, if wagon box is not got back to original position, even stopping brake lock unclamps, also do not have the brake ground signalling, vehicle can't travel.
Embodiment 2
Present embodiment is example with the aerial lift device with insulated arm.Be the utility model is installed in the operator's compartment of aerial lift device with insulated arm with the difference of embodiment 1.When vehicle in neutral gear, parking, when carrying out aloft work, the brake ground signalling is arranged, power take-off valve is a closure state, the 1st intermediate relay Q1 coil is charged, it is located at the open contact J1 closure on the vehicle-mounted emergent computer power line, vehicle-mounted emergent computer switch K2 is got to closed position, vehicle-mounted emergent computer work.If driving engine occurs flame-out, vehicle-mounted emergent computer can start Emergency Hydraulic Pump automatically, and insulation bucket arm is withdrawn from the high-altitude, and staff's safety is fallen to the ground.
Embodiment 3
With the various special vehiclees that Hydraulic Pump is housed on the chassis is example, is with the difference of executing example 1 or 2: the utility model is installed in the operator's compartment of the special vehicle that Hydraulic Pump is housed on the various chassis.Close power take-off valve K1 if forget in the prior art, Hydraulic Pump is in vehicle ', pressure is directly proportional with Vehicle Speed, the pressure that hydraulic tubing bears is the several times of rated pressure, then hydraulic tubing can be because the excessive fatigue that causes of pressure, be prone to unexpected booster, change speed gear box, part-time case and fragile.Vehicle of the present utility model is installed, if forget before startup and close power take-off valve K1, stopping brake lock is a releasing orientation, the ground signalling of not braking, the power takeoff coil is not charged, and Hydraulic Pump can't be worked, normal vehicle operation has effectively been avoided the serious consequence that above-mentioned maloperation produced.
In the various embodiments described above, all can in the operator's compartment of vehicle, be provided with the 1st, 2 indicator lamp D1, D2, also can on each indicator lamp, distinguish siren horn in parallel (as buzzer phone), in running order with caution vehicle-mounted emergent computer of navigating mate or power takeoff.
