Embodiment
Be elaborated below in conjunction with the embodiment of accompanying drawing to the utility model.Should be understood that embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
Fig. 2 is the skeleton diagram of controller that is used to protect starting motor according to the utility model embodiment.
As shown in Figure 2, the utility model provides a kind of controller 5 that is used to protect starting motor 3, and starting motor 3 links to each other with power supply and is used for ato unit, and this controller 5 comprises: timing device 12 is used for picking up counting from the moment of starting motor ato unit; And treatment device 14, link to each other with timing device 12, be used for reaching the scheduled time and break off the power supply of starting motor 3 during value in timing device 12 timing.
Through in the engineering mechanical device of for example full hydraulic excavator, using this controller 5, can avoid driver's long-time operation key enable switch 1 and the starting motor 3 that causes damages or the phenomenon of discharged or defective battery.Thereby realized protection to starting motor 3 and storage battery.
In the present embodiment; This controller 5 also comprises the reception unit 10 that is connected with timing device 12; Wherein, In the moment of starting motor 3 ato units, reception unit 10 is used to receive the power source voltage signal and sends timing device 12 to, and timing device 12 picked up counting from the moment that receives voltage signal.
In the present embodiment, treatment device 14 breaks off the lasting scheduled time of power supply of starting motor 3.Like this, can avoid the operator last once start not success after, ato unit and cause starting motor 3 or the unnecessary damage of storage battery once more in a short period of time.
Wherein, the scheduled time can be in 5 seconds to 10 seconds scope, and in the present embodiment, the scheduled time is 10 seconds.
The utility model also provides a kind of system that is used to protect starting motor; Comprise the key enable switch 1 that is connected between starting motor 3 and the power supply; This system also comprises the controller that is connected with power supply through key enable switch 1, and this controller is a controller 5 of protecting starting motor 3 being used in the foregoing description.
In the present embodiment, this system also comprises: relay 4, this relay 4 are connected between starting motor 3 and the key enable switch 1; Wherein, Controller 5 is electrically connected with this relay 4, is used for reaching the scheduled time during value in timing device 12 timing, controls this relay 4 and breaks off.
Wherein, controller 5 can be programmable logic controller (PLC) (PLC), single-chip microcomputer, field programmable gate array (FPGA) etc.
The utility model also provides a kind of engineering mechanical device, comprises starting motor 3 and the motor that is connected with this starting motor 3, and this project machinery comprises that also being used in the foregoing description protect the system of starting motor.This project machinery for example can be an excavator.
Fig. 3 is the circuit diagram of system that is used to protect starting motor according to the utility model embodiment.
As shown in Figure 3; Starting motor power supply (VCC) is connected to starting motor 3 through insurance unit 2, key enable switch 1; The terminal 86 of relay 4 connect the output terminal of controller 5, terminal 85 ground connection, and normally-closed contact 30 is connected starting motor 3 and key enable switch 1 respectively with 87a.When the normally-closed contact 30 and 87a conducting of relay 4, when driver's operation key enable switch 1, key enable switch 1 closure; Thereby starting motor 3; The output shaft of this starting motor 3 links to each other with the bent axle of motor machinery, drives the crankshaft rotating of motor, thus ato unit; After driver's hand left this key enable switch 1, key enable switch 1 can automatically reset, and this moment, starting motor 3 also can be thrown off and being connected of engine crankshaft because of outage.
The working principle of system that is used to protect starting motor of the utility model is described below in conjunction with Fig. 4.
After key enable switch 1 closure, the power source voltage signal sends starting motor 3 to through relay 3, starting motor 3 ato units, and this voltage signal is sent to controller 5 simultaneously.Controller 5 picked up counting from the moment that receives voltage signal; Starting motor 3 runs well during the timing, reaches scheduled time during value (for example a value between 5 seconds to 10 seconds, those skilled in the art can set according to actual needs) in timing device 12 timing; The normally opened contact 30 and 87 conductings of controller 5 these relays 4 of control; And normally-closed contact 30 breaks off with 87a, thereby starting motor 3 and power supply are broken off, and stops the long-time running of starting motor 3.In this case, even if the operator because during false judgment and long-time ato unit, starting motor 3 also can not turn round, thereby has protected starting motor 3 and storage battery.
In addition, the operator after the failure of last once ato unit, ato unit once more in a short period of time possibly, but in the short time continuously ato unit can cause very big harm to starting motor 3 and storage battery.For addressing this problem, the normally-closed contact 30 of controller 5 control relays 4 breaks off and must continue a scheduled time with 87a, and just the normally-closed contact 30 of control relay 4 and 87a can conductings, operates just ato unit once more of key enable switch 1 this moment.Particularly, time lag timing that can be through 5 pairs of key enable switch 1 double actions of controller, make time of key enable switch 1 double action must reach the Preset Time section after, confirm control relay 4 conductings.For example the time lag fitness for purpose of the double startup of key enable switch 1 was not less than 10 seconds, and controller 5 control relays 4 break off the predetermined amount of time that is continued and can be 10 seconds like this.Just, the operator last must be after once starting failure at ato unit once more after 10 seconds at interval, otherwise can't operation start motor 3.
Can find out from the foregoing description: controller is through breaking off the power supply of starting motor after the running scheduled time at starting motor; Avoided operator's long-time operation to start key operation deactivation motor; Perhaps last once start failure after, deactivation motor and cause the unnecessary damage of starting motor or storage battery system again in a short period of time.Thereby reduced the phenomenon of unusual damage engine cranking motor, reduced user's construction risk and hazard rate, had the advantage simple, convenient, reliable, that cost is low.
More than combine accompanying drawing to describe the preferred implementation of the utility model in detail; But; The utility model is not limited to the detail in the above-mentioned mode of execution; In the technical conceive scope of the utility model, can carry out multiple simple variant to the technological scheme of the utility model, these simple variant all belong to the protection domain of the utility model.
Need to prove that in addition each the concrete technical characteristics described in above-mentioned embodiment under reconcilable situation, can make up through any suitable manner.For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible compound modes.
In addition, also can carry out combination in any between the various mode of execution of the utility model, as long as its thought without prejudice to the utility model, it should be regarded as content disclosed in the utility model equally.
