Description
Technical field
The utility model relates to and belongs to hoisting crane technical field, particularly relates to a kind of explosion-proof crane with hoisting controller.
Background technology
Hoisting crane in the market, its large dolly each mechanism that hoists uses conial motor, makes hoisting crane can reach the braking of steady failure-free and start.If adopt the contactless switch of traditional type to control, frequent owing to playing braking, cause contactless switch to be often in open and-shut mode, there will be phenomenon of arc discharge simultaneously, contacts of contactor ablation phenomen is very serious, this just makes electric controling element service life reduction, 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, bring great inconvenience to user.Pre-buried two temperature resistances on motor winding, a pre-buried temperature resistance on motor housing.At normal temperatures, when exceeding design temperature, resistance becomes suddenly large to temperature resistance.Transfer the signal to the hoisting controller input, break during overtemperature mechanism motors.This carrys out very big inconvenience to hoisting crane long journey handling and load material strip.My company is for above Problems existing, 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 a kind of hoisting crane of safety factor high-band hoisting controller is designed and developed.
Utility model content
The technical problems to be solved in the utility model is: the explosion-proof crane of the band hoisting controller providing a kind of safety factor high.
The technical scheme that the utility model is taked for the technical matters existed in solution known technology is:
With an explosion-proof crane for hoisting controller, comprise explosion-proof crane, it is characterized in that: also comprise crane controller and craneman's electric switch; Wherein: connected by RS485 data line between described crane controller and craneman's electric switch;
Described crane controller is electrically connected with the button that opens/stop controlling explosion-proof crane by electronic power switch; Described crane controller is electrically connected with 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 utility model additionally uses 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.
The advantage that the utility model has and good effect are:
One, because the crane controller in the utility model is electrically connected with the button that opens/stop controlling explosion-proof crane by electronic power switch, therefore the excellent switching characteristic that power application electronic switch " zero current " is opened and " zero pressure difference " turns off starts or stops electrical motor frequently, and actv. solves and uses " arcing " during mechanical switch start and stop electrical motor to burn contact phenomenon and electromagnetic interference;
Two, because the crane controller in the utility model is electrically connected with the motor driver of explosion-proof crane by mechanical relay, therefore mechanical relay contact advantage low in energy consumption can be utilized to keep the running of electrical motor, effectively reduce the temperature rise that in electronic power switch operational process, pressure drop power consumption produces;
Three, due to the craneman's electric switch in the utility model be provided with LCD Liquid Crystal Display screen, therefore breakdown signal can quickly move through LCD Liquid Crystal Display screen show;
Four, because the crane controller in the utility model is provided with aluminum alloy casing, therefore there is the advantage of anti-electromagnetic interference;
Five, because the craneman's electric switch in the utility model is provided with electronic lock circuit, therefore can prevent that there is the maloperation between relevance Action Button;
Six, because the explosion-proof crane in the utility model is provided with energy back feed device, the power consumption heat element by 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 utility model under two kinds of modes;
Fig. 2 is the electric main loop circuit figure of explosion-proof crane of the present utility model under two kinds of modes;
Fig. 3 is the external structure of craneman's electric switch in the utility model.
Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, 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, comprise outside the necessary component of traditional explosion-proof crane, also comprise crane controller and craneman's electric switch; Wherein: connected by RS485 data line between crane controller and craneman's electric switch; Crane controller is electrically connected with the button that opens/stop controlling explosion-proof crane by electronic power switch; Crane controller is electrically connected with 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, lower button, 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 that there is the maloperation between relevance Action Button, craneman's electric switch preferably arranges electronic lock circuit.
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.Like this when explosion-proof crane hangs loads decline, hoisting crane is now by potential energy load, and electrical operation is in the generating operation mode of fourth quadrant; electric energy delivers to frequency converter by motor is counter; frequency changer direct current bus voltage is raised, and if do not discharged, after reaching certain voltage, frequency converter can automatically be protected and shut down.After adopting energy back feed device, reduce cal val object simultaneously in realization, by electric energy feedback to Dian Wangzhong district, also save electric energy
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
