Description
Technical field
The utility model relates to a kind of electric controll winch system.
Background technology
In new national standard, the security requirement that the winch for colliery runs is more and more higher.In inclined shaft hoisting, lifting of winch must surprisingly slip the car stop of car containing preventing from causing large tank.In former electric controll winch, electric controll winch is electric controll winch, car stop is automatically controlled is that car stop is automatically controlled, and both do not contact, during each setting winch, installation two is needed to overlap PLC control system, two cover distance measurement sensors, not only make control circuit bother, improve installation cost, and two cover control system also easily produce conflict, run also less stable.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of electric controll winch system, by same PLC control system achieve simultaneously manipulate electric controll winch and car stop automatically controlled, system is simplified greatly, improves the stability of system.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of electric controll winch system, comprise PLC control cabinet, operating unit, winch mechanical hook-up and prevent-moving car mechanical hook-up, PLC control cabinet inside is provided with PLC control system, control signal is also transferred to PLC control cabinet by described operating unit display running status, described PLC control cabinet controls four-quadrant frequency converter according to the control signal received and drives winch mechanical hook-up to run, described winch mechanical hook-up is connected with the first scrambler and the second scrambler, and send displacement signal to PLC control cabinet by the first scrambler and the second scrambler, PLC control cabinet controls prevent-moving car mechanical hook-up by the displacement signal accepted, described PLC control cabinet control linkage has Hydraulic Station.
Further, described first scrambler is speed pickup, and is arranged on cylinder side, and described second scrambler is speed pickup, and is arranged on motor side.
Further, described prevent-moving car mechanical hook-up comprises car stop, and car stop is provided with arrester.
The beneficial effect adopting technique scheme to produce is: the utility model is combined by the controlling functions of the PLC control cabinet by prevent-moving car control module and winch, eliminate the trouble of the scrambler that other installation site is detected, also eliminate the scrambler in prevent-moving car control module simultaneously, the stationary problem of the relevant components and parts of PLC and man-machine interface and the man-machine display part of car stop and car stop and electric controll winch, drop to cost, simplify winch to install, debug process, decrease possible trouble spot, improve the stability of electric controll winch system.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As depicted in figs. 1 and 2; a kind of electric controll winch system of the utility model; comprise PLC control cabinet, operating unit, winch mechanical hook-up and prevent-moving car mechanical hook-up; PLC control cabinet inside is provided with PLC control system; control signal is also transferred to PLC control cabinet by described operating unit display running status; described PLC control cabinet controls four-quadrant frequency converter according to the control signal received and drives winch mechanical hook-up to run, and PLC control cabinet controls the operation of frequency converter according to the control signal of operating unit and various guard signal and formulates the braking of lock.Four-quadrant frequency converter drives winch motor to run, and drags mine car and runs back and forth in tunnel, promote or transfer weight.Described winch mechanical hook-up is connected with the first scrambler and the second scrambler, and send displacement signal to PLC control cabinet by the first scrambler and the second scrambler, PLC control cabinet controls prevent-moving car mechanical hook-up by the displacement signal accepted, and described PLC control cabinet control linkage has Hydraulic Station; Described first scrambler is speed pickup, and is arranged on cylinder side, and described second scrambler is speed pickup, and is arranged on motor side; Described prevent-moving car mechanical hook-up comprises car stop 4, and car stop 4 is provided with arrester 5.Car stop 4 is the run locations according to mine car, automatic lifting or put down arrester, and when preventing the connecting link between the wire rope pulling mine car or mine car from occurring fracture, mine car slips car.Because once there is slipping car phenomenon, due to tunnel short have one or two hundred meters, long has upper km, and the mine car glided at a high speed not only can hit pipeline, cable in rotten tunnel, and can cause serious life injury to the staff below tunnel.
The utility model can according to the operation conditions of mine car, carries out exceeding the speed limit, overtravel protection, and carries out automatic retarding and automatically stop; and adopt Dual-encoder to carry out distance velocity measuring; when a scrambler breaks down, system will stop-working protection, greatly reduces the probability of malfunction that position is detected.Not only accurately but also safety therefore the calculating to mine car position of electric controll winch; The position signalling that car stop adopts Dual-encoder to gather, system accurate coefficients is high, safe and reliable, does not tightly simplify difficulty of construction, has dropped to system cost, but also improves the stability of system.
The utility model is combined by the controlling functions of the PLC control cabinet by prevent-moving car control module and winch, eliminate the trouble of the scrambler that other installation site is detected, also eliminate the stationary problem of the scrambler in prevent-moving car control module, PLC and the relevant components and parts of man-machine interface and the man-machine display part of car stop and car stop and electric controll winch simultaneously, drop to cost, simplify winch installation, debug process, decrease possible trouble spot, improve the stability of electric controll winch system.
