Utility model content
The purpose of this utility model is to provide a kind of stable vehicle-mounted cable take-up and pay-off device, it can raising equipment the safety of operation, when retractable cable generation tension, clamping stagnation, can automatically alleviate.
Problem described in the utility model realizes with following technical proposals:
A stable vehicle-mounted cable take-up and pay-off device, it comprises cable elevator dish, electric machine controller, motor, driving band and bearing seat, and described cable elevator dish is by bearing block support in frame, and described motor is by driving band driving cable elevator disc spins; Described motor controller controls motor rotation.
Above-mentioned stable vehicle-mounted cable take-up and pay-off device, described electric machine controller is comprised of two comparators, joint denial gate, relay and combined aural and visual alarm, wherein, electric machine controller is provided with voltage and current two-way incoming signal, described two-way incoming signal is input to respectively "+" end of two comparators, "-" end of comparator provides reference voltage, is concatenated into power supply obtains by the one the first resistance R 1 and the second resistance R 2; The two paths of signals of described comparator output is connected to the input end of joint denial gate, and the output of joint denial gate is connected to the base stage of aerotron Q1, and the collector load of aerotron Q1 is relay and combined aural and visual alarm, and the normally closed contact of relay is controlled the break-make of motor.
Above-mentioned stable vehicle-mounted cable take-up and pay-off device is being connected in series respectively the first diode D1 or the second diode D2 in the output loop of two comparators.
Above-mentioned stable vehicle-mounted cable take-up and pay-off device is distinguished and follows the 3rd diode D3 or the 4th diode D4 between "+" ends of two comparators and mouth.
The utility model has designed a kind of stable vehicle-mounted cable take-up and pay-off device, compared with the prior art, it can judge the tension force of vehicle mounted electric folding and unfolding drum, when overtension, disconnect the power supply of drive motor, thereby avoided cable clamping stagnation to cause pulling force to increase and damage that cable is caused.The utility model is simple in structure, easy operating, and in service do not have too much mechanical wear, reduced equipment loss and maintenance cost yet.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1. be physical construction schematic diagram of the present utility model;
Fig. 2 is electrical schematic diagram of the present utility model.
In figure, each list of reference numerals is: 1, cable elevator dish, 2, electric machine controller, M, motor, 5, driving band, 6, bearing seat, 7, braking mechanism, Q1, aerotron, IC1A, IC1B, comparator, J1 relay, U2, OR-NOT circuit, FMQ, combined aural and visual alarm, D1, the first diode, D2, the second diode, D3, the 3rd diode, D4, the 4th diode, S, Hall element.
The specific embodiment
As shown in Figure 1 and Figure 2, the cable elevator dish 1 in the utility model is bearing in frame by bearing seat 6, and described motor M is by driving band 5 driving cable elevator disc spins; Described electric machine controller 2 is controlled motor rotation.Motor M is connected on source of AC, connects Hall element S in its major loop.
Electric machine controller circuit is provided with the input of voltage and current two-way, and this two-way incoming signal is input to respectively "+" end of two comparator IC1A, IC1B, and "-" end of comparator provides reference voltage, is concatenated into power supply obtains by the first resistance R 1 and the second resistance R 2.The two paths of signals of described comparator output enters joint denial gate U2, and the output of joint denial gate is connected to the base stage of aerotron Q1, and the collector load of aerotron Q1 is relay J 1 and combined aural and visual alarm FMQ, and the normally closed contact J1-1 of relay controls the break-make of motor M.When relay energized action, and combined aural and visual alarm FMQ also sends chimes of doom simultaneously.
Principle of work of the present utility model is, when cable normally moves, motor carries out work with certain torque, and voltage signal is lower than the benchmark voltage of comparator "-" end, comparator LM324+export high level after the voltage ratio of end and-end.In like manner, by the Hall element S being serially connected in motor main circuit, gather "+" end that current signal inputs to comparator IC1B, the output of comparator is connected to joint denial gate U2, the level signal of joint denial gate output changes according to the size of electric current, thereby control conducting or the cut-off of aerotron Q1, relay J 1, in normally off, is controlled motor in normal operation.
When there is catching phenomenon in cable, the torque of motor will change, and this variation will directly be reflected on the operating voltage and electric current of motor, when the operating voltage of motor and electric current surpass setting value, comparator LM324 is output as high level, as long as the input end of joint denial gate 74HC02 has one to be input as high level, export high level, thereby make aerotron Q1 conducting, relay adhesive, normally closed contact disconnects, the output of cutting off the electricity supply, and indicator lamp is lighted and buzzer phone sounding simultaneously.Voltage or current signal abnormal corresponding cable tension or clamping stagnation, cut off motor power supply, will protect cable not because damaging appears in clamping stagnation.
It is 74HC02 that joint denial gate U2 in the utility model adopts model, and comparator adopts discharge circuit chip, and model is LM324.
