When opening zero-bit or zero-bit failure, vehicle cannot start.In normal production, once zero-bit failure causes vehicle that cannot open
Dynamic, maintenance personal must judge that directive property is indefinite for failure, and the erroneous judgement of failure is be easy to cause to lead to the expansion of production accident
Change.
Therefore, there are also to be developed for the prior art.
Utility model content
Place in view of above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide the zero of a kind of bridge crane
Position monitoring system.Aim to solve the problem that existing crane troubleshooting difficulty is larger, the low problem of production efficiency.
In order to achieve the above object, the utility model takes following technical scheme:
The utility model provides a kind of zero-bit monitoring system of bridge crane, including cart zero-bit contact, main carriage zero
Position contact, secondary trolley zero-bit contact, main raising zero-bit contact, secondary raising zero-bit contact, which is characterized in that further include zero-bit relay
Device, indicator light, urgent zero relay and breaker；The anode of power supply is sequentially connected in series cart zero-bit contact, the touching of main carriage zero-bit
Point, secondary trolley zero-bit contact, main raising zero-bit contact, secondary raising zero-bit contact, and it is electrically connected one end of zero relay, it is described
The other end of zero relay is connect with power cathode；The indicator light is in parallel with the opened point of zero relay, indicator light with
NOT gate is additionally provided on conducting wire between zero relay；The urgent zero relay respectively with cart zero-bit contact, main carriage
Zero-bit contact, secondary trolley zero-bit contact, main raising zero-bit contact, secondary raising zero-bit contact shunt, the anode of power supply are sequentially connected
The positive pin of breaker, urgent zero relay, the negative pin of urgent zero relay are connected with the cathode of power supply.
Further, at least one group opened point on the zero relay and urgent zero relay.
Further, cart zero-bit contact, main carriage zero-bit contact, secondary trolley zero-bit contact, the touching of main raising zero-bit
Point, secondary raising zero-bit contact set that there are two screw holes, are fixed by screws on the handle of crane corresponding position.
Further, the indicator light is mounted on the drivers' cab joint action table of crane.
Further, the coil voltage of the supply voltage and zero relay and urgent zero relay is 24V.
The utility model is compared with prior art: operating system is simplified, when zero-bit failure, even if being unfamiliar with people to equipment
Member or overhead traveling crane operator can see whether being that vehicle caused by zero-bit failure cannot start from the state of indicator light quickly.
When certain mechanism handle zero-bit failure, equipment can start, but the failure mechanism can not act, and both ensure that safety, equipment also can
Enough emergency startings, reduce failure cost.
Detailed description of the invention
Fig. 1 is the utility model crane zero-bit monitoring system work wiring schematic diagram；
