The utility model discloses a start-up protection system for a loader. The loader start-up protection system comprises a storage battery, a generator, a starter and an ignition switch. The power terminals are connected, the positive pole of the battery, the start gear of the ignition switch, the switch of the start protection relay and the control terminal of the starter are connected in sequence, the positive pole of the battery, the power-on gear of the ignition switch, the charging indicator light and the neutral terminal of the generator are connected in sequence Connected, the coil of the start protection relay is connected in parallel with the charging indicator light. Damage to drive gears by repeated starts can be avoided. It can prevent the starter from repeatedly starting and overtaking for a long time. The starter drive gear and the one-way device are effectively protected, and the failure rate of the starter is reduced. The structure is simple, the connection is convenient, the operation is reliable, and the stability and safety of the electrical system can be effectively improved. Used to protect the starter of the loader engine.
Description
Technical field
The utility model relates to a kind of protective gear of loader Starter.
Background technique
At present, on loader motor, Starter does not have protective gear, is one of product that rate of fault is the highest.This is that Starter working principle is due to short time duty design, the Starter operating time slightly length will damage.Remove outside Starter design itself and quality problems, most of reason that Starter damages is that operator are long starting time.Modally be exactly repeated priming and surmount when long, this act of operation very easily damages Starter.
Summary of the invention
In order to overcome known Starter, there is no protective gear, slightly long flimsy defect of operating time, the utility model provides a kind of loader starting protection system, and this loader starting protection system can protect Starter can not damage.
The technical solution of the utility model is: this loader starting protection system comprises storage battery; generator; Starter; ignition switch; the positive pole of storage battery is connected with the positive pole of generator by insurance; the positive pole of storage battery is connected with the power supply terminal of Starter; the startup gear of the positive pole of storage battery, ignition switch, the switch of starting protection relay and the control terminal of Starter are sequentially connected; the gear that powers on of the positive pole of storage battery, ignition switch, charging indicator light are sequentially connected with the neutral end of generator, and the coil of starting protection relay is in parallel with charging indicator light.
The utility model has the advantages that: can avoid by repeated priming infringement actuation gear.Can avoid the infringement that Starter still works on Starter is caused after engine start.In the time of can preventing Starter repeated priming and length, surmount.Effectively protect Starter actuation gear and one-way element, reduced the rate of fault of Starter.Simple in structure, easy to connect, reliable operation, stability and the Security that can effectively improve electrical system.
Accompanying drawing explanation
Fig. 1 is an embodiment's of the present utility model electrical block diagram.
Embodiment
In Fig. 1, this loader starting protection system comprises storage batteries D C, generator F, Starter Q, ignition switch, the positive pole of the positive pole of storage batteries D C+by insurance BX1 and generator F+be connected, the positive pole of storage batteries D C+be connected with the power supply terminal 30 of Starter Q, the positive pole of storage batteries D C+, the startup gear start of ignition switch, the switch J-1 of starting protection relay J is sequentially connected with the control terminal 50c of Starter Q, the positive pole of storage batteries D C+, the gear on that powers on of ignition switch, charging indicator light D is sequentially connected with the neutral end D+ of generator F, the coil of starting protection relay J is in parallel with charging indicator light D.
The positive pole of storage batteries D C+be connected with electrical apparatus for vehicle use load FZ by another insurance BX2.Starting protection relay J voltage is selected 24V voltage.
When ignition switch is placed in, power on gear during on, neutral end D+ voltage is 0V, and charging indicator light D is bright.Now, starting protection relay J coil obtains electric, and the switch J-1 of starting protection relay J is closed.When ignition switch is placed in startup gear start, starting circuit is connected, Starter Q work.After motor F starts, generator F also works simultaneously, and now neutral end D+ voltage is greater than 24V, and charging indicator light D extinguishes.The power-off of starting protection relay J, Starter Q quits work.Can find out, starting protection relay J is also short time duty.
