Description
Technical field
The utility model relates to a kind of device controlling motor auto extinguishing.
Background technique
Relay is a kind of electronic control device, and it has control circuit and working circuit, is usually applied in automatic control circuit, and it is actually the one " recloser " removing to control larger working circuit electric current with less control circuit electric current.
Its principle of double-wound relay is that the magnetic force design of two coils is different, and one of them coil is used for making relay adhesive, i.e. starting coil; And the magnetic force of another coil is generally not enough to make the actuating of relay, even if but energising after starting coil power-off, still can guard relay at attracting state, i.e. hold-in winding.
Fork truck is one of carrying vehicle of commonly using of present people, be that member pallet cargo carries out loading and unloading, stacking and short distance transport, weight transport operation various wheeled carrying vehicle.Be widely used in harbour, station, airport, goods yard, factory floor, warehouse, Transfer center and DISTRIBUTION CENTRE etc., and can enter carry out pallet cargo in cabin, compartment and shipping container handling, transport operation, be requisite equipment in palletized transport, Container Transport.
At present on the fork truck not having controller, motor is when stopping for a long time, can not auto extinguishing, therefore when driver is at needs long term stop due to carelessness forget kill engine or away from keyboard after again because other things stop over, cause engine long time idle running, thus cause very large waste of fuel.
Given this, the present inventor develops a kind of device controlling motor auto extinguishing specially, and this case produces thus.
Model utility content
A kind of device controlling motor auto extinguishing that the utility model provides, it can when the long-time idle running of fork truck, and automatically controlled engine stops working, and decreases the waste of fuel.
To achieve these goals, the technical solution of the utility model is as follows:
Control a device for motor auto extinguishing, comprise initiation key switch, seat switch, the time relay, double-wound relay and main circuit relay, initiation key switch is connected with power electric respectively with the time relay, the control circuit of the time relay is connected with power electric by seat switch, the control circuit of main circuit relay passes through working circuit and the electrical connection of initiation key switch of double-wound relay, initiation key switch has 3 switch contacts, be respectively break contact, operating contact and startup work double-contact, initiation key switch to be placed in after startup work double-contact by elastic structure self-return to operating contact place, the working circuit electrical connection of operating contact and double-wound relay, startup work double-contact is electrically connected with the working circuit of double-wound relay and the starting coil interface of control circuit respectively, the working circuit of the time relay and the hold-in winding interface electrical connection of double-wound relay.
Described elastic structure is spring.
After adopting such scheme, during the utility model startup fork truck, turn initiation key switch connection is to starting work double-contact, now the starting coil of double-wound relay and hold-in winding work simultaneously, connect main circuit relay, fork truck starts, after starting, initiation key switch return only contacts with operating contact, and double-wound relay continues to connect its working circuit under the effect of hold-in winding.When driver leaves seat, now seat switch disconnects, time relay deferred action, when after time delay certain hour, time relay action disconnects its working circuit, now the hold-in winding power-off of double-wound relay, double-wound relay working circuit disconnects, make the power-off of main circuit relay, cause main circuit to disconnect, forklift engine stops working; Only need sit on the seat when restarting, initiation key switch be revolved and puts startup work double-contact place, can restart, thus reach the purpose of this utility model.
Accompanying drawing explanation
Fig. 1 is the entity circuit diagram of the utility model embodiment;
Fig. 2 is the schematic diagram of the utility model embodiment initiation key switch.
Label declaration
Initiation key switch 1, break contact A, operating contact B, start work double-contact C, the time relay 2, double-wound relay 3, starting coil interface 12, hold-in winding interface 14, main circuit relay 4, spring 5.
Embodiment
As shown in Figure 1-2, be a kind of device controlling motor auto extinguishing that the utility model discloses, comprise power supply, initiation key switch 1, seat switch, the time relay 2, double-wound relay 3 and main circuit relay 4; Initiation key switch 1 is connected with power electric respectively with the time relay 2, the control circuit of the time relay 2 is connected with power electric by seat switch, the control circuit of main circuit relay 4 is electrically connected by the working circuit of double-wound relay 3 and initiation key switch 1, initiation key switch 1 has 3 switch contacts, be respectively break contact A, operating contact B and start work double-contact C, initiation key switch 1 to be placed in after startup work double-contact C by spring 5 self-return to operating contact B place; The working circuit electrical connection of operating contact B and double-wound relay 3, startup work double-contact C is electrically connected with the working circuit of double-wound relay 3 respectively and the starting coil interface 12 of control circuit is electrically connected; The working circuit of the time relay 2 and the hold-in winding interface 14 of double-wound relay 3 are electrically connected.
After adopting such scheme, during the utility model startup fork truck, turn initiation key switch 1 is switched to startup work double-contact C, now the starting coil of double-wound relay 3 and hold-in winding work simultaneously, connect main circuit relay 4, fork truck starts, and initiation key switch 1 return under the effect of spring 5 after starting, only contacts with operating contact B, double-wound relay 3 continues to connect its working circuit under the effect of hold-in winding, and fork truck keeps starting state.
When driver leaves seat, now seat switch disconnects, the time relay 2 deferred action, when after time delay certain hour, the time relay 2 action disconnects its working circuit, the now hold-in winding power-off of double-wound relay 3, double-wound relay 3 working circuit disconnects, and makes main circuit relay 4 power-off, causes main circuit to disconnect, forklift engine stops working, and namely reaches order of the present utility model.
When restarting, need sit on the seat, connect seat switch, the time relay 2 is worked, and at this moment the hold-in winding of double-wound relay 3 obtains electric, then initiation key switch 1 is revolved and put startup work double-contact C place, make the starting coil of double-wound relay 3 obtain reset, due to now hold-in winding electric, so double-wound relay 3 returns to working state, make main circuit relay 4 again electric, now just can restart fork truck.
Wherein the delay time of the time relay 2 is preferably 5 minutes, and client can regulate according to actual needs.
These are only preferred embodiment of the present utility model, the restriction not to protection domain of the present utility model.All equivalent variations done according to the mentality of designing of this case, all fall into the protection domain of this case.
