Abstract
The invention discloses a crane electrical control device, which is characterized by comprising a remote control transmitter, a remote control receiver and a control box body, wherein the remote control receiver outputs signals to a PLC input end, and the PLC controls operation of the motor through an alternating current contactor. According to the crane electrical control device, an operator does not need to stand near the crane for operation, safety of the operator is improved, corrosion of chemical gases is reduced as the electrical control box is moved indoors, corrosion on the electrical component by gases can be reduced, electrical fault is thus reduced, the maintenance cost is saved, the crane is controlled in a remote control mode, and the operation is convenient and safe. The invention also relates to an operation method for the crane electrical control device.
Description
Technical field
The present invention relates to a kind of overhead traveling crane electrical control gear, relate to particularly a kind of handling safety, the remote-controlled overhead traveling crane electrical control gear that electric fault is few; The invention still further relates to the method for operating of this overhead traveling crane electrical control gear.
Background technology
At present, known overhead traveling crane electric control box is installed on lifting motor shell, adopt traditional A.C. contactor electric and mechanical interlocked, by line handle, control A.C. contactor closure and realize electric machine rotation, and then control 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, electric cabinet is subject to gas attack for a long time in top, electrical equipment often breaks down, when serious, cause burn-down of electric motor, when impact is produced, improve maintenance cost, and because electric cabinet is arranged on overhead traveling crane lifting motor position, each maintenance all needs to ascend a height, and dangerous accident and maintenance difficult easily occur.
Summary of the invention
The present invention aims to provide that a kind of circuit is simple, easy-to-operate, effectively reduce the corrosion of etchant gas to electric box, and then minimizing electric fault, the overhead traveling crane electrical control gear of maintenance safe ready, to solve the operational hazards existing at present, electric fault rate is high, the problems such as maintenance difficult.
For achieving the above object, technical scheme of the present invention is: by original overhead traveling crane electric box is transformed, electric cabinet is drawn to electric control chamber or transfer the position that environment is good and be convenient to keep in repair, each motor power-supply wire is caused to each motor connects, above overhead traveling crane, only has like this each motor power-supply wire, reduce greatly corrosion and electric fault, reduce etchant gas control box is corroded.Control section adopts industrial remote control transmitter, by panel button, transmit to receiver of remote-control sytem, receiver outputs signal to Programmable Logic Controller PLC by the signal correspondence of receiving, the coil that outputs signal to A.C. contactor after carrying out by PLC internal processes, motor operation is connected in A.C. contactor action.
The invention has the beneficial effects as follows: overhead traveling crane electrical control gear of the present invention, operating personnel do not need to stand in the place operation very near apart from overhead traveling crane, improve operating personnel's safety, electrical control cabinet is moved to indoor minimizing chemical gases corrosion, so not only can reduce the corrosion of gas to electrical equipment, and then reduce electric fault, save maintenance cost, mode by remote control is controlled overhead traveling crane, easy to operate, safety.
