Abstract

The utility model relates to a vehicle starting device, in particular to a starting device convenient to start a vehicle out of a cab. A control loop comprises a key switch and a starting relay. The control loop is characterized in that the control loop further comprises a control relay, a neutral position switch, a subsidiary starting button, a subsidiary flameout button, a flameout relay and a flameout electromagnetic valve, wherein the key switch is connected with a coil of the control relay in series to form into the control loop, a contact point of the control relay, the neutral position switch, the subsidiary starting button and the starting relay are connected with each other in series to form into a subsidiary starting loop, and the subsidiary flameout button, the flameout relay, the flameout electromagnetic valve and the key switch are connected with each other in series to form into a flameout loop. The vehicle starting device has the beneficial effects that maintenance personnel can normally starts and flames out the vehicle under the vehicle after the cab is overturned, so that the correlative system is convenient to overhaul, the maintenance efficiency of the vehicle is improved, and the maintenance cost is reduced.

Description

A kind of vehicle launch

Technical field

The utility model relates to a kind of vehicle launch, particularly a kind of starting arrangement of being convenient to starting outside operator cabin.

Background technique

Existing vehicle launch generally is to adopt the key operation that is installed in the operator cabin to control, the break-make of the starter relay power supply that key operation control starter motor carries.Key operation is when " START " shelves, and starter relay gets electric, the starter motor starting; Key operation return " ON " shelves, the starter relay outage.If desired behind driver's cab turnover, pilot engine, when maintenance vehicle related system and other device, operator cabin is very inconvenient about.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of device of being convenient to starting outside operator cabin.

For solving the problems of the technologies described above, the technical solution of the utility model is:

A kind of vehicle launch, its control loop comprises key operation and starter relay, the coil of its key operation and control relay is formed control loop, it is characterized in that, its control loop also comprises controlled relay, neutral switch, secondary starting button, secondary flame-out button, flame-out relay, flame-out solenoid valve, wherein the coil of key operation and control relay is composed in series control loop, the contact of control relay, neutral switch, secondary starting button and starter relay are composed in series secondary start loop, secondary flame-out button, flame-out relay, flame-out solenoid valve and key operation are composed in series flame-out loop.

Between described key operation and control relay, insurance is set, between described key operation and flame-out relay, insurance is set, between described key operation and starter relay, insurance is being set, between described control relay and neutral switch, insurance is set.It is excessive and short circuit occurs and burn wire harness that insurance can be protected the electric current of interlock circuit.

The beneficial effects of the utility model are after being implemented in driver's cab turnover, and the maintenance man is normal starting and flame-out power operation under car, is convenient to carry out the maintenance of related system, has improved the maintenance efficiency of vehicle, reduce maintenance cost.

Description of drawings

Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described in detail.

Fig. 1 is an embodiment's of the utility model circuit theory diagrams.

Embodiment

As shown in Figure 1, a kind of special car starting arrangement, comprise the control gear that key operation 1, control relay 2, neutral switch 3, secondary starting button 4, secondary flame-out button 5, flame-out relay 6, flame-out solenoid valve 7, starter relay 8, starter motor 9 are formed, wherein key operation 1 is composed in series control loop with the coil of control relay 2, the contact of control relay 2, neutral switch 3, secondary starting button 4 are composed in series secondary start loop with starter relay 8, and secondary flame-out button 5, flame-out relay 6, flame-out solenoid valve 7 are composed in series flame-out loop with key operation 1.Insurance 10 is set between described key operation 1 and control relay 2, insurance 11 is set between described key operation 1 and flame-out relay 6, insurance 12 is set between described key operation 1 and starter relay 8, insurance 13 is set between described control relay 2 and neutral switch 3.

When key operation 1 is in the ON shelves, control relay 2 electrical contacts closed, vehicle is in neutral state simultaneously, neutral switch 3 closures, press secondary starting button 4 after, starter relay 8 electrical contacts closed, starter motor 9 electric just can normal starting; After relevant maintenance is finished, press secondary flame-out button 7, flame-out relay 6 gets electric contact and disconnects, flame-out solenoid valve 7 outages, and motor 9 oil-breaks are flame-out.

Because this device can driven field operation by the maintenance user of service, has exempted repeatedly the puzzlement of operator cabin up and down.

It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.

Claims
