Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1, the power control of a kind of crawler dozer that the utility model provides, it is the electric power thus supplied for controlling between crawler dozer power supply and body, and it mainly comprises electromagnetic switch 100, load wire harness 200, positive source wire harness 300, power main switch 400, power cathode wire harness 500 and minus earth wire harness 600.
Electromagnetic switch 100, it is specially electromagnetic relay, its coiler part access control loop.
Load wire harness 200, its one end connects the top connection of electromagnetic switch 100 contact, and the other end connects load.
Positive source wire harness, its one end connects the lower contact of electromagnetic switch 100 contact, and the other end connects power supply 700 positive terminal.
Power main switch 400, it is for controlling power supply 700 and the energising situation of bull-dozer, can carrying out the switching between connecting and disconnecting.
Power main switch 400 is specially the hand switch with removable key, like this after manually power supply and complete machine negative pole being disconnected, hand switch key can be extracted, and can effectively prevent from, because misoperation causes being closed by switch by mistake, substantially increasing fail safe.
Power cathode wire harness 500, its one end connects power supply 700 anode connector, and the other end connects the top connection of power main switch 400.
Minus earth wire harness 600, its one end connects the lower contact of power main switch 400, and the described power cathode wire harness other end connects the top connection of power main switch.
By the connected mode of above-mentioned parts, can effectively reduce power shortage situation, and car load power supply can be cut off quickly and safely.
