Abstract
The many motor starting devices of a kind of internal combustion engine generator group, one end of the normally opened contact of the power supply contactor of each motor is connected with power supply, the other end is connected between sectional pressure element and the motor, be connected in series with each motor power supply contactor coil of parallel connection again after the travel switch contact serial connection of each motor shaft, formed a logical control circuit, thereby guaranteed to have only the pinion wheel of whole starter motor output shafts all to mesh just energising startup, avoided not meshing the overload that causes other motor because of the gear of indivedual starter motors with large fluted disc.
Description
Technical field
The utility model belongs to internal combustion engine generator group control technology field, relates in particular to a kind of novel many motor starting devices of internal combustion engine generator group.
Background technology
The starting resistance square of high-power internal combustion engine generator group is bigger, and the fire speed height all was to adopt the more powerful starter motor of separate unit in the past, and the startup wheel box by heaviness drives the internal combustion engine generator group and starts.This starter gear heavy, volume are big, complex structure, vibration and noise are big, install and adjust trouble, cost height.Adopt many schemes that the micro-machine parallel connection starts simultaneously, can overcome the shortcoming of the big electric motor starting scheme of above-mentioned separate unit.But,, just may cause other motor overload and scaling loss if the gear of the motor that wherein has withstands in the time of can not meshing on the canine tooth wheel disc.
Summary of the invention
The purpose of this utility model overcomes the deficiency of above-mentioned prior art exactly, provides a kind of and has only the gear of whole starter motors all to mesh the many motor starting devices of internal combustion engine generator group that just energising starts with large fluted disc.
The purpose of this utility model is existing like this: the many motor starting devices of a kind of internal combustion engine generator group, form by starting switch, at least two starter motors and power supply contactor thereof and pilot relay, one end of the normally opened contact of the power supply contactor of each motor is connected with power supply, the other end is connected between sectional pressure element and the motor, is connected in series with each motor power supply contactor coil of parallel connection after the travel switch contact serial connection of each motor shaft again.
Adopt the technical solution of the utility model, the coil tandem of each motor power supply contactor that the travel switch contact serial connection of each motor shaft is back and in parallel, formed a logical control circuit, thereby the pinion wheel that has guaranteed to have only whole starter motor output shafts all with the large fluted disc engagement after just energising start, avoided not meshing the overload scaling loss that causes other motor because of the gear of starter motors individually.
Description of drawings
Accompanying drawing 1 is the circuit diagram of the utility model embodiment.
Embodiment
Referring to Fig. 1, the many motor starting devices of internal combustion engine generator group of the present utility model, starter motor M1, M2 adopt series DC machine, and they are connected to 24 volts of direct supplys with after separately sectional pressure element J13, J23 is connected in series through starting switch AN.In order to improve the suction of pilot relay to armature, sectional pressure element J13, the J23 of present embodiment also is an ancillary coil of pilot relay simultaneously.Pilot relay main coil J12, the J22 of each motor is respectively with motor M 1 branch road, motor M 2 branch roads and connect.Be connected in series with each motor power supply contactor coil C1, C2 of parallel connection again after travel switch contact J11, the J21 serial connection of each motor shaft.The end of normally opened contact C1c, the C2c of the power supply contactor of each motor is connected with power supply by starting switch AN, and the other end is connected on respectively between the sectional pressure element and motor of each motor branch road.
When starting the internal combustion engine generator group, press starting switch AN, the major-minor coil electricity of pilot relay, the motor shaft that pinion wheel is housed is released, because of string on the motor branch road has sectional pressure element, so supply voltage all is not added on the motor, motor shaft slowly rotates, and is meshed with large fluted disc on the internal combustion engine output shaft.After the pinion wheel of all motor shafts all puts in place with the large fluted disc engagement, travel switch contact J11, J21 closure, each motor power supply contactor coil C1, C2 energising, thereby make normally opened contact C1c, C2c closure, supply voltage directly is added on the field copper and armature of each motor, and all motors just begin fast rotational work simultaneously.If wherein the pinion wheel of any one motor shaft hits and can not mesh on large fluted disc when putting in place, its corresponding travel switch contact just can not be closed so, thereby power supply contactor coil C1, C2 just can not switch on, and all motors are not worked.
Claims (1)
1, the many motor starting devices of a kind of internal combustion engine generator group, form by starting switch, at least two starter motors and power supply contactor thereof and pilot relay, an end of normally opened contact that it is characterized in that the power supply contactor of each motor is connected with power supply, the other end is connected between sectional pressure element and the motor, is connected in series with each motor power supply contactor coil of parallel connection after the travel switch contact serial connection of each motor shaft again.
