Abstract
The utility model provides an anti-explosion electrical starting interlock protection mechanism. The anti-explosion electrical starting interlock protection mechanism comprises an engine, an anti-explosion starter motor used for controlling the engine to start and an anti-explosion electrical starting control circuit. A first starting relay is arranged in the anti-explosion electrical starting control circuit in a series connection mode. A second starting relay is further arranged in the anti-explosion electrical starting control circuit. One end of a normally open contact of the second starting relay is connected with the negative electrode of a power supply, and the other end of the normally open contact of the second starting relay is connected with a coil of the first starting relay. The second starting relay is also connected with an oil pressure switch and a starting switch in series. A protection circuit formed by the second starting relay, the oil pressure switch and the starting switch is connected with the anti-explosion electrical starting control circuit in parallel. An oil circuit of the oil pressure switch is communicated with an engine oil circuit of the engine. The anti-explosion electrical starting interlock protection mechanism is simple in structure; since oil pressure signals of the engine are used for interlock protection of an anti-explosion electric starter, damage caused by misoperation to the anti-explosion electric starter can be reduced.
Description
Technical field
The utility model relates to automobile engine starting technical field, relates in particular to a kind of anti-explosion electric and starts interlock protection mechanism.
Background technique
The most of anti-explosion electric Starting mode that uses of underground mine use explosion-proof engine at present; adopt flame-proof type electric starters to do power; electric starter is mainly used in controlling the across-the-line starting of three-phase squirrel-cage induction motor, stops and forward and reverse running, and can and disconnected shield mutually to the overload of motor.
But due to colliery power operation peopleware and Environmental Conditions limited, operating habit is bad, often can cause overload; or short circuit phenomenon; and general electric starter is without overload and short circuit protection system, therefore cause electric starter often to damage, affect manufacturing efficiency.
Summary of the invention
Technical problem to be solved in the utility model is the technical deficiency to above-mentioned existence just; provide a kind of simple in structure; utilize engine oil pressure interlocking of signals protection anti-explosion electric starter motor, reduce anti-explosion electric starter motor and start interlock protection mechanism because misoperation causes the anti-explosion electric that electric starter damages.
The utility model solves the technological scheme that its technical problem adopts:
A kind of anti-explosion electric starts interlock protection mechanism, include motor and the explosion-proof actuating motor for control engine starting, and anti-explosion electric starts control circuit, in anti-explosion electric startup control circuit, be in series with the first starting relay, it is characterized in that: in described anti-explosion electric startup control circuit, be also provided with the second starting relay, the normally opened contact one termination power cathode of the second starting relay, another termination first starting relay coil; The second starting relay is also in series with oil pressure switch and enable switch, and the protective circuit of three's composition is in parallel with anti-explosion electric startup control circuit; The oil circuit of described oil pressure switch communicates with the engine oil passage of motor.
In such scheme, described anti-explosion electric starts between control circuit and motor, and flame proof regulator is also installed.
The principle of the utility model device is that before engine start, oil pressure switch contact, in closed state, seals in oil pressure switch contact in the coil of the second starting relay.The second starting relay normally opened contact closure after switch starter closure, the first starting relay coil electricity, the first starting relay normally opened contact closure, main starting circuit is connected motor and is started starting, now engine oil pressure is less than oil pressure switch working value, and explosion-proof actuating motor keeps working state until engine start success.After engine start success, engine oil pressure impels oil pressure switch action, contact separation, even if now operator's misoperation continues closed switch starter, the coil of the first starting relay and the second starting relay also cannot obtain electric, thereby ensures to there will not be reignition to beat tooth phenomenon.
Main beneficial effect of the present utility model is:
The utility model mechanism structure is simple, utilizes engine oil pressure interlocking of signals protection anti-explosion electric starter motor, reduces anti-explosion electric starter motor and damages because misoperation causes electric starter.
