Abstract
The utility model discloses a kind of bridge crane electric clamp automatic control devices, including total contactor；Total contactor coil is connected with the normally opened contact of total contactor output relaying；Total contactor coil and clamp power circuit breaker coil, clamp cable drum power circuit breaker coils from parallel connection of coils；The clamp power circuit breaker coil, clamp cable drum power circuit breaker coils from parallel connection of coils；The coil of total contactor output relaying is connect with PLC.The utility model realizes the automatic control of electric clamp power supply, convenient for overhead traveling crane driver operation, it is effective to save operating procedure, so that clamp is after closing main contactor, directly it is electric, main contactor clamp power loss is disconnected after operation, is eliminated on overhead traveling crane driver to crane crossbeam upper switch electric clamp power supply.
Description
Technical field
The utility model relates to bridge crane electric clamp automatic control devices.
Background technique
On overhead traveling crane driver's arrival machine after power cabinet, clamp power circuit breaker in manual power turn-on cabinet needs after operation
Clamp power circuit breaker is disconnected manually, if replacing different cold coilings, needed using different travelling overhead crane apparatus, therefore clamp power supply
It gives so that job step is relatively complicated.Meanwhile if driver in the case where forgetting to finish clamp power supply after operation, goes back
Additional electricity consumption will be caused to waste.
Utility model content
Technical problem to be solved in the utility model is, in view of the shortcomings of the prior art, it is electromechanical to provide a kind of overhead traveling crane
Dynamic clamp automatic control device so that clamp is after closing main contactor, directly it is electric, main contactor is disconnected after operation and is pressed from both sides
Power loss is clamped, is eliminated on overhead traveling crane driver to crane crossbeam upper switch electric clamp power supply.
A kind of in order to solve the above technical problems, the technical scheme adopted by the utility model is: bridge crane electrical clip
Clamp automatic control device, including total contactor；Total contactor coil is connected with the normally opened contact of total contactor output relaying；
Total contactor coil and clamp power circuit breaker coil, clamp cable drum power circuit breaker coils from parallel connection of coils；The clamp
Power circuit breaker coil, clamp cable drum power circuit breaker coils from parallel connection of coils；The coil and PLC of total contactor output relaying
Connection.
The PLC is connect with control switch.
Compared with prior art, have the beneficial effect that the utility model realizes electric clamp possessed by the utility model
The automatic control of power supply is convenient for overhead traveling crane driver operation, effectively saves operating procedure, so that clamp is after closing main contactor,
Directly it is electric, after operation disconnect main contactor clamp power loss, eliminate on overhead traveling crane driver to crane crossbeam upper switch
Electric clamp power supply.
Detailed description of the invention
Fig. 1 is the utility model embodiment circuit diagram.
Specific embodiment
As shown in Figure 1, the utility model installs contactor additional between electric clamp under electric clamp power circuit breaker and machine, from
And realize contactor control, breaker lower collar thread is parallel to overhead traveling crane main contactor suitable for reading, mouth parallel connection clamp power supply under contactor
Route.Since when overhead traveling crane is in operation, main contactor must be attracted, so that clamp after closing main contactor, directly obtains
Electricity disconnects main contactor clamp power loss, eliminates on overhead traveling crane driver to crane crossbeam upper switch electrical clip after operation
Clamp power supply.
This circuit realizes clamp power supply suspension control switch ZC control.ZC is closed, and clamp obtains electric；ZC is disconnected, clamp power loss.
In Fig. 1, A1-C22K15 is total contactor output relaying, and A1-KM3 is total contactor coil, and KQ1 is clamp power supply,
KQ2 is clamp cable drum power supply.After ZC is closed, feedback to PLC power supply closes signal, so that C22K15 coil is obtained electric, Fig. 1 by PLC
Middle A1-C22K15 normally opened contact closure, A1-KM3, KQ1, KQ2 coil it is electric；ZC has no progeny, and feedback arrives PLC power supply break signal,
Make C22K15 coil losing electricity by PLC, A1-C22K15 normally opened contact disconnects in Fig. 1, the equal power loss of A1-KM3, KQ1, KQ2 coil.
The control power supply of P4E21, P4E22 control circuit thus, P6B71 are wiring wire size.
Using the device of the utility model, the time required to eliminating bridge machine operation up and down, directly complete to control in drivers' cab,
About 5 seconds time-consuming, single saves the time 205 seconds.
