By employing the above technical scheme, the explosion-proof crane has the advantages of high safety coefficient and good heat radiation performance.
Description
Technical field
The present invention relates to belong to hoisting crane technical field, particularly relate to a kind of explosion-proof crane with hoisting controller.
Background technology
Hoisting crane in the market, what its large dolly hoisted each mechanism's use is conial motor, makes hoisting crane can reach steady failure-free braking and starting.If adopting the contactless switch of traditional type controls, frequent owing to playing braking, cause contactless switch often in open and-shut mode, there will be arcing phenomenon simultaneously, contacts of contactor ablation phenomen is very serious, this just makes the electric controling element life-span reduce, especially the button ablation in pocket torch door control handle is serious, and when problem occurs in any mechanism, is all difficult to the source of pinpointing the problems, search problem and bother very much, to user, bring great inconvenience.Pre-buried two temperature resistances on motor winding, a pre-buried temperature resistance on motor housing.At normal temperatures, when surpassing design temperature, it is large that resistance becomes suddenly temperature resistance.Transfer the signal to the hoisting controller input, overtemperature Shi Duandiao mechanism electrical motor.This carrys out very big inconvenience to hoisting crane long journey handling and load material strip.My company is for the problem of above existence, and according to home and abroad Aeronautics and Astronautics career development demand, the crane control system with high-end technology has been expanded in exploitation, to adapt to more intelligent, the modern development of Crane Industry, and improves hoisting crane technology competition ability in industry.Therefore design and develop a kind of hoisting crane of safety factor high-band hoisting controller.
Summary of the invention
The technical problem to be solved in the present invention is: the explosion-proof crane with hoisting controller that a kind of safety factor is high is provided.
The technical scheme that the present invention takes for the technical matters existing in solution known technology is:
An explosion-proof crane with hoisting controller, comprises explosion-proof crane, it is characterized in that: also comprise crane controller and craneman's electric switch; Wherein: between described crane controller and craneman's electric switch, by RS485 data line, connect;
Described crane controller is electrically connected to the button that opens/stop of controlling explosion-proof crane by electronic power switch; Described crane controller is electrically connected to the motor driver of explosion-proof crane by mechanical relay; Described craneman's electric switch is provided with LCD Liquid Crystal Display screen, scram button, switching button, arrow button; Described crane controller is provided with aluminum alloy casing.
As optimal technical scheme, the present invention has also adopted following technical scheme:
Described craneman's electric switch is provided with electronic lock circuit.
Described explosion-proof crane is provided with energy back feed device.
Advantage and good effect that the present invention has are:
One, because the crane controller in the present invention is electrically connected to the button that opens/stop of controlling explosion-proof crane by electronic power switch, therefore the good switching characteristic that power application electronic switch " zero current " is opened and " zero pressure difference " turn-offs starts or stops electrical motor frequently, and " arcing " that actv. has solved while using mechanical switch start and stop electrical motor burns contact phenomenon and electromagnetic interference;
Two, because the crane controller in the present invention is electrically connected to the motor driver of explosion-proof crane by mechanical relay, the running that therefore can utilize mechanical relay contact advantage low in energy consumption to keep electrical motor, effectively reduces the temperature rise that in electronic power switch operational process, pressure drop power consumption produces;
Three, because the craneman's electric switch in the present invention is provided with LCD Liquid Crystal Display screen, so breakdown signal can show by LCD Liquid Crystal Display screen rapidly;
Four,, because the crane controller in the present invention is provided with aluminum alloy casing, therefore there is anti-electromagnetic interference;
Five,, because the craneman's electric switch in the present invention is provided with electronic lock circuit, therefore can prevent thering is the maloperation between relevance Action Button;
Six, because the explosion-proof crane in the present invention is provided with energy back feed device, the power consumption heat element that is about to explosion-proof crane is replaced by energy feedback unit, therefore reduces the generation of heat.
Accompanying drawing explanation
Fig. 1 is the electric control loop circuit diagram of explosion-proof crane of the present invention under two kinds of modes;
Fig. 2 is the electric main loop circuit figure of explosion-proof crane of the present invention under two kinds of modes;
Fig. 3 is the external structure of craneman's electric switch in the present invention.
The specific embodiment
For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, Fig. 2, a kind of explosion-proof crane with hoisting controller, comprises outside the necessary member of traditional explosion-proof crane, also comprises crane controller and craneman's electric switch; Wherein: between crane controller and craneman's electric switch, by RS485 data line, connect; Crane controller is electrically connected to the button that opens/stop of controlling explosion-proof crane by electronic power switch; Crane controller is electrically connected to the motor driver of explosion-proof crane by mechanical relay; Crane controller is provided with aluminum alloy casing.Refer to Fig. 3, craneman's electric switch is provided with LCD Liquid Crystal Display screen, scram button, switching button, arrow button; Above-mentioned arrow button comprises: upper button, knob down, left button, right button, front button, rear button.
Wiring relation between crane controller and explosion-proof crane refers to following table 1
Table 1 is the wiring relation between crane controller and explosion-proof crane
As preferably, on the basis of above-mentioned specific embodiment, in order to prevent thering is the maloperation between relevance Action Button, electronic lock circuit is preferably set on craneman's electric switch.
As preferably, on the basis of above-mentioned arbitrary specific embodiment, in order to reduce the generation of heat, therefore the power consumption heat element of traditional explosion-proof crane is replaced by energy back feed device.When explosion-proof crane hangs loads decline, hoisting crane is now subject to potential energy load like this, and electrical operation is in the generating operation mode of fourth quadrant; electric energy is by the anti-frequency converter of delivering to of motor; frequency changer direct current bus voltage is raise, if do not discharged, reach after certain voltage frequency converter protection and shutting down automatically.Adopt after energy back feed device, realizing minimizing cal val object simultaneously, by electric energy feedback Dao Dianwangzhong district, also saved electric energy
Above embodiments of the invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the present patent application scope and improvement etc., within all should still belonging to patent covering scope of the present invention.
