Because the height of the single-rope winding type hoister is limited by the rope containing amount of the roller, and the hoisting capacity is limited by the strength of a single steel wire rope, the single-rope winding type hoister cannot meet the requirements of mines with high well depth and high yield, and the multi-rope friction type hoister is widely applied at present. The YXZ type multi-rope hoisting steel wire rope tension automatic balancing suspension device solves the problem that the lengths of a plurality of first ropes are inconsistent and ensures that the stress of the plurality of ropes is consistent because the lengths of the plurality of first ropes of the multi-rope friction type hoisting machine cannot reach the length consistency of each steel wire rope in the use process; the device is characterized in that: 1. the closed-loop passive hydraulic communication automatic balance adjusting system is adopted, and the tension automatic balance of the steel wire rope in a dynamic state and a static state can be realized at high precision. 2. The automatic tension balance of the hoisting steel wire rope can be realized in dynamic and static states; 3. the tension difference of the steel wire rope caused by the diameter error of the rope groove of the roller can be reduced without stopping and adjusting; 4. the stress change of the steel wire rope caused by the rigidity error of the steel wire rope can be reduced or eliminated; 5. the service life of the steel wire rope can be effectively prolonged, and rope breakage accidents caused by unbalanced tension are reduced. 6. The abrasion of the elevator liner can be greatly reduced, and the service life of the liner is prolonged. The turning liner, the tension testing and the balance adjusting can be greatly reduced or cancelled, and the maintenance workload is reduced. 7. Can reduce the times of adjusting the rope cutting of the tank.
The working principle of the suspension device is as follows: closed loop passive hydraulic connections. No matter when the steel wire rope moves or is static, as long as tension difference exists among the steel wire ropes, the steel wire rope with large tension compresses the communicated oil cylinder through the middle plate, the cushion block, the side plate and the pressing plate to enable the piston rod of the communicated oil cylinder to compress, the suspension extends, the tension of the steel wire rope becomes small, oil liquid in the oil cylinder enters the communicated oil cylinder with small tension through the communicating pipe to enable the piston rod of the communicated oil cylinder to extend outwards, the suspension is shortened through the cushion block, the middle plate, the pressing plate and the side plate, the tension of the steel wire rope becomes large, and the communicated oil cylinder correspondingly stops moving until the tension of each steel wire rope is equal.
But the online state detection of this device can't realize always, because the industrial and mining of field production is more complicated, and the pressure in this suspension cylinder is great simultaneously, and long can take place the sealing washer to damage, phenomenon such as valve fracture directly leads to the hydro-cylinder pressure release. If the tension cannot be found for a long time, the tension of the steel wire rope is uneven, the single rope of the lifting container is stressed, and safety accidents are easy to happen.
