Description
Technical field
The present invention relates to the device of a kind of quick replacing ground-type multi-cable friction drive hoist head rope and tail rope.
Background technology
The handling labor of multi-rope friction hoisting machine more complicated with respect to cylindrical drum hoist, because must keep every rope capacity of multi-rope friction hoisting machine to equate, thereby the work capacity of replacing, inspection, adjustment steel rope is increased, particularly change rope work.According to the 379th regulation of China's " safety regulations in coal mine "; The useful life of friction drive hoist steel rope (being head rope) must not be above 2 years, the useful life of balance rope (being tail rope) must not surpass 4 years, therefore, is the mine of friction drive hoist for major and minor well, need to change head rope every year on average No. one time, tail rope of replacing in 2 years.At present, the rope changer that adopt in each ore deposit mainly is oneself processing, owing to do not have regular design and calculation of strength, exists the problem of rope changer insufficient strength, is the hidden danger that mine safety is produced.Simultaneously, because main electromotor is asynchronous with stable car, exist rope to turn round strength, twist dog leg, newly steel rope and old steel rope, new steel rope and problems such as new steel rope is twisted together directly influence the quality of changing rope, even can make new rope impaired, injured, jeopardize the safety of mine.
Summary of the invention
Purpose of the present invention is exactly to overcome above-mentioned the deficiencies in the prior art, provide a kind of and shorten the rope time of changing, improve safety and reduce the quick rope changer of ground-type multi-cable friction drive hoist of labor strength.
The present invention includes stepping and changed rope mechanism, anti-rope mechanism and the automatic monitoring alarm of running.Stepping is changed rope mechanism and is included stepping oil cylinder, clamping mechanism and base; The stepping oil cylinder is a two-way ram bar hydraulic actuating cylinder; Clamping mechanism includes upper holder block, lower lock block, double acting single-piston-rod hydraulic cylinder, big rocking bar, little rocking bar and bearing pin; The lower lock block of stepping oil cylinder one end and clamping mechanism is by Bolt Connection, and upper holder block and lower lock block couple together by big rocking bar, little rocking bar and bearing pin, and the double acting single-piston-rod hydraulic cylinder is installed between two big rocking bars by bearing pin.Base is fixed on the ground.
The anti-rope mechanism of running includes sleeve, wire rope handling pipe, gland, wedge, spring and spring perch, hydraulic actuating cylinder, erecting frame, pin, U type card, needle valve lubricating cup and channel-section steel; Spring, spring perch, wedge are put into sleeve, and sleeve and gland are by bolted connection, and the needle valve lubricating cup is installed on the sleeve; U type card is fixed on hydraulic actuating cylinder on the erecting frame, and hydraulic actuating cylinder links to each other with channel-section steel by pin, and channel-section steel and wedge are adjacent.
Automatic monitoring alarm includes the pressure monitoring alarm mechanism and runs rope monitoring, alarming mechanism.The pressure monitoring alarm mechanism includes A/D converter, pressure sensor, PLC, relay and modular pressure.Run rope monitoring, alarming mechanism and include tachogenerator, solenoid directional control valve, A/D converter, PLC and relay.The pressure monitoring alarm mechanism is installed in to be prevented running on the hydraulic actuating cylinder of rope mechanism.The tachogenerator that runs rope monitoring, alarming mechanism contacts with new steel rope by rubber wheel, and PLC sends the action of signal control solenoid directional control valve.
Upper holder block and lower lock block inside face scribble polyamine fat friction material.Pressure sensor is a silicon diffusion pressure sensor.
The pressure monitoring alarm mechanism is according to the start-stop of the variation control motor of force value.Run rope monitoring, alarming mechanism and the straight-line motion of steel rope is converted into rotatablely moves, the new lowering velocity of steel rope is converted into electric signal, electric signal is passed to PLC, sends the action of signal control solenoid directional control valve.
The principle of work that rope mechanism is changed in stepping is: during fuel feeding, stepping oil cylinder piston bar stretches out the drive clamping mechanism and moves forward; Not during fuel feeding, the oil return of stepping oil cylinder, clamping mechanism resets.And steel rope is passed between lower lock block and upper holder block, by stretching of double acting single-piston-rod hydraulic cylinder, drive the motion of big rocking bar, thereby realize the folder rope of clamping mechanism and the function of slack rope.The present invention adopts " old rope band newly restrict suspensions, the old rope of new rope band reclaims " disposable rope scheme of changing, and has introduced stepping simultaneously and has changed the mechanism that restricts steel rope is sent into head sheave and cylinder, has guaranteed to change the quality of rope.The upper and lower briquetting inside face that rope mechanism is changed in stepping scribbles polyamine fat friction material, can shield to steel rope, has guaranteed to change the quality of rope.
Thereby whether the pressure monitoring alarm mechanism adopts PLC control motor control oil pump to the hydraulic actuating cylinder fuel feeding, utilizes pressure sensor to detect force value and also changes digital signal into through modular pressure.PLC will compare from the digital signal and the pressure given value of modular pressure, as the opening, stop of control signal control motor, and has dynamic LED force value and alarm display.Display lamp is that pump is given the hydraulic actuating cylinder repairing for the work of red expression electrical motor, then represents electrical motor for green to be failure to actuate, and represents to run the automatic mechanism for monitoring of rope and move when the traffic lights interlace flicker.Running rope detection alarm mechanism utilizes tachogenerator to record the steel rope lowering velocity.When speed during greater than setting value, PLC sends instruction, and steel rope is held in anti-hydraulic actuating cylinder oil return of running rope mechanism tightly, and display lamp be a redness simultaneously.
The present invention is applicable to the gig in difference rope footpath.It can realize the quick replacing of gig steel rope, and is simple in structure, reliable in action, and it is few to take equipment, has reduced working strength of workers, and the engineering time is short, only finishes with just 500 meters steel ropes being transferred 0.5 working day.Because of steel rope is to change simultaneously, stressed more even, reduce the wearing and tearing of steel rope.All mechanism, sensor, the electrical controllers of fast quick change rope system all are located at well head, conveniently use, are convenient to operation.Remarkable in economical benefits.
