The utility model discloses a kind of overhead traveling crane electrical control gear, it is characterized in that, comprise remote control transmitter, receiver of remote-control sytem and control box body, described receiver of remote-control sytem outputs signal to PLC input end, and described PLC controls motor by A.C. contactor and runs.This overhead traveling crane electrical control gear, operating personnel do not need to stand in the very near place operation of distance overhead traveling crane, improve the safety of operating personnel, electrical control cabinet is moved to the corrosion of indoor minimizing chemical gases, so not only can reduce the corrosion of gas to electrical equipment, and then reduce electric fault, save maintenance cost, overhead traveling crane is controlled, easy to operate, safety by the mode of remote control.
Description
Technical field
The utility model relates to a kind of overhead traveling crane electrical control gear, relates to a kind of handling safety particularly, the remote-controlled overhead traveling crane electrical control gear that electric fault is few.
Background technology
At present, known overhead traveling crane electric control box is installed on lifting motor shell, adopt traditional A.C. contactor electrically with mechanical interlocked, closed by line handle control A.C. contactor and realize electric machine rotation, and then controlling overhead traveling crane action, this kind of method of operating is for this hoisting device of overhead traveling crane, because coiled handset cord restriction personnel need stand in the very near place operation of distance elevating thing, greatly dangerous, often there is dangerous accident; And at chemical workshop, seriously corroded, it is long-term by gas attack that electric cabinet is in top, electrical equipment often breaks down, cause burn-down of electric motor time serious, while impact is produced, improve maintenance cost, and be arranged on overhead traveling crane lifting motor position due to electric cabinet, each maintenance all needs to ascend a height, and easily dangerous accident occurs and maintenance difficult.
Summary of the invention
The utility model aims to provide that a kind of circuit is simple, easy-to-operate, effectively reduce etchant gas to the corrosion of electric box, and then minimizing electric fault, the overhead traveling crane electrical control gear of maintenance safe ready, to solve the operational hazards existed at present, electric fault rate is high, the problems such as maintenance difficult.
For achieving the above object, the technical solution of the utility model is: by transforming original overhead traveling crane electric box, by electric cabinet traction to electric control chamber or transfer environment good and be convenient to maintenance position, each motor power-supply wire is caused that each motor connects, each motor power-supply wire is only had like this above overhead traveling crane, great minimizing corrosion and electric fault, reduce etchant gas and corrode control box.Control section adopts industrial remote control transmitter, transmit to receiver of remote-control sytem by panel button, receiver outputs signal to programmable controller PLC by the signal correspondence received, output signal to the coil of A.C. contactor after being performed by PLC internal processes, A.C. contactor action is connected motor and is run.
The beneficial effects of the utility model are: overhead traveling crane electrical control gear of the present utility model, operating personnel do not need to stand in the very near place operation of distance overhead traveling crane, improve the safety of operating personnel, electrical control cabinet is moved to the corrosion of indoor minimizing chemical gases, so not only can reduce the corrosion of gas to electrical equipment, and then reduce electric fault, save maintenance cost, overhead traveling crane is controlled, easy to operate, safety by the mode of remote control.

Wherein, 1. remote control transmitter, 2. button, 3. transmit antenna, 4. remote signal receiver, 5. power supply and signal end, 6. programmable controller PLC, 7.PLC input end, 8.PLC output terminal.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with embodiment also with reference to accompanying drawing, the utility model is further described.Should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
As shown in Figure 1, this overhead traveling crane electrical control gear, comprises remote control transmitter, receiver of remote-control sytem and control box body.
As shown in Figure 2, remote control transmitter 1 has 8 action buttons 2 above, wherein 7 is single speed button (top to bottom, left and right, front and rear, for subsequent use), and 1 is always stopped button (general supply button), and attaching antenna 3 can extend command range about 100 meters.By powered battery, safe and reliable.
In figure 3, power supply and the signal end 5 of remote signal receiver 4 comprise power supply terminal, public terminal, signal output terminal etc., signal output terminal is connected with the input end 7 of Programmable Logic Controller 6, signal is provided to PLC, external power source button, stop control as outside other or spacing device sends signal to the input end 7 of PLC, after being performed by Programmable Logic Controller 6 internal processes, the output terminal of Programmable Logic Controller 6 sends signal and connects contactor, makes the performer actions such as motor.
Electrical control cabinet is moved to power distribution room above electric car, only need extend each motor power-supply wire.
When operating, to close general supply, operating personnel only need stand in home, first unclamp and always stop button above remote control transmitter 1, then remote control transmitter 1 direction indicator button is pressed according to demand, remote control transmitter 1 just sends signal, remote signal receiver 4 receives corresponding signal, performed by internal circuit, output contact closes, corresponding signal is exported to the respective input of Programmable Logic Controller 6 by connection line, Programmable Logic Controller 6 starts to perform by the program of internal composition, the lead-out terminal of setting is connected, the coil of A.C. contactor is obtained electric, connect contactor main contacts, after contactor is closed, connect corresponding motor power, corresponding motor energized action, realize production requirement, when overhead traveling crane moves to each limit, corresponding travel switch action closes, the closed corresponding input end of Programmable Logic Controller 6, corresponding contactor coil power supply is disconnected by internal processes, contactor main contacts is disconnected and then cuts off motor power, if there is electric wire open failure, maintenance personal can ascend a height, just can repair or replace electric elements on ground, convenient, safety, reliably.
Should be understood that, above-mentioned embodiment of the present utility model only for exemplary illustration or explain principle of the present utility model, and is not formed restriction of the present utility model.Therefore, any amendment made when not departing from spirit and scope of the present utility model, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.In addition, the utility model claims be intended to contain fall into claims scope and border or this scope and border equivalents in whole change and modification.
