Abstract
The utility model discloses an automatic pull force balancer for rope taper sleeves of an elevator. The automatic pull force balancer comprises steel ropes and steel rope taper sleeves at the top ends of the steel ropes, pull rods are connected at the other ends of the steel rope taper sleeves, shock proofing springs are arranged at the other ends of the pull rods, pull rod sleeves are sleeved on the pull rods, hydraulic cylinders are arranged on one sides of the steel rope taper sleeves, the pull rods and the pull rod sleeves penetrate the hydraulic cylinders, rope head plates for positioning the pull rod sleeves are mounted at the top ends of the hydraulic cylinders, relative sealed spaces are formed by the hydraulic cylinders and the rope head plates, piston sleeves are mounted on sections, in the hydraulic cylinders, of the pull rod sleeves, and balancing liquid shunt pipe systems are arranged between the hydraulic cylinders. The automatic pull force balancer is structurally improved reasonably by particularly adding the hydraulic cylinders and the balancing liquid shunt pipe systems. Via the balancing liquid shunt pipe systems, hydraulic pressure cooperation in the hydraulic cylinders is adjusted, borne tensile forces of the steel ropes are balanced, and service life of the elevator is effectively prolonged.
Description
Technical field
The utility model relates to the elevator technology field, particularly a kind of elevator rope tapered sleeve pulling force autobalance.
Background technology
According to existing known technology, elevator must be equipped with steel cable and connect on car and the balance counterweight, with steel cable suspension in the groove of electrical motor hole, when electrical motor rotates, drive steel cable and realize the control elevating function, and the age limit of elevator steel cable becomes urgent problem day by day, trace it to its cause, except the quality of steel rope own, repeatedly bending, dimensional problem etc. show outside the reason, the equalization of strain of steel rope becomes more importantly factor, and the present steel cable that normally fixes elevator two by spring, because error is made in the restraining of traction race, the diameter error of steel rope, the reasons such as distance accumulation error of each root steel wire real-world operation during the elevator operation, causing can't be accurately with the adjustment of steel cable range ability error, and the elevator operation can produce vibration and sympathetic response, the simultaneously tension force of each bar steel cable and inhomogeneous, also can increase the wearing and tearing of steel cable, reduce the service life of steel cable and the comfort level of elevator.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of elevator rope tapered sleeve pulling force autobalance.
The technical scheme that its technical matters that solves the utility model adopts is:
Elevator rope tapered sleeve pulling force autobalance, comprise steel cable and the steel cable tapered sleeve that is arranged on the steel cable top, the other end of described steel cable tapered sleeve is connected with pull bar, the other end of described pull bar then is provided with shock-proof spring, described drag link sleeve is equipped with the pull bar external member, this pull bar external member upper end is provided with limit coil, one end of described shock-proof spring is connected with limit coil, the other end of described shock-proof spring then is stuck under the bolt that is installed on the pull bar, the opposite side of described steel cable tapered sleeve also is provided with hydraulic actuating cylinder, described pull bar and pull bar external member are passed hydraulic actuating cylinder, described hydraulic actuating cylinder upper end is equipped with for the rope hitch plate to pull bar external member location, the space of described hydraulic actuating cylinder and a relative sealing of rope hitch plate formation, described pull bar external member part in hydraulic actuating cylinder is equipped with piston bush, is provided with equilibrium liquid shunt conduit system between the described hydraulic actuating cylinder.
Monitor the working condition of balancing device in order to be more convenient for, described hydraulic actuating cylinder is outside equipped with the steel cable seat, is provided with the Monitoring and Positioning bar on this steel cable seat, on the described Monitoring and Positioning bar displacement monitoring device is installed.
The beneficial effects of the utility model are: this balancing device is by rational structure of modification, the particularly design of hydraulic actuating cylinder and equilibrium liquid shunt conduit system, utilize the differential pressure automatic stream theorem of liquid, cooperate by the hydraulic pressure in the equilibrium liquid shunt conduit system regulator solution cylinder pressure, realize the pulling force of bearing of each bar steel cable of balance, reduced because steel cable pulling force overbalance causes the easily phenomenon of wearing and tearing of steel cable, cable wheel, reduce car resonance altogether toot, the service life of Effective Raise elevator.
