Abstract

The utility model discloses a lifter with a compensation steel cable, which is composed of a car, a driving wheel, a hoist rope, a counterweight, the steel cable, a guide device, a compensation steel cable, etc. The driving wheel drives the hoist rope which drives the car and the counterweight to run up and down along respective guide track. The compensation steel cable is composed of steel cable chain rings which are connected together and have definite quantity and continuous metal ropes; the steel rope chain ring are provided with corresponding holes, and the metal ropes are threaded into the holes of the steel rope chain rings. The steel cable chain rings are limited to form relative rotation without causing mutual collision by using the toughness of the metal ropes or wires, and accordingly, the running noise of the utility model is eliminated.

Description

The elevator of band compensating rope

The utility model relates to a kind of elevator with compensating rope, belongs to lifting machinery.

The elevator of existing band compensating rope, as Chinese patent application number: the 94105271 (applyings date: on April 5th, 1994), name is called " compensation and rope elongation arrangment ", the charging system of this elevator, the elevator that comprises cage, counterweight, one group of dangling cage and counterweight cable wire that dangles, hauling block, the motion of this pulley transfers to elevator and counterweight through dangling cable wire, and one group of compensating rope and belong to this group at least one angle pulley of wireline system that dangles, and be useful on the buffer device of counterweight.Compensating rope dangle than with the dangling of the cable wire that dangles than identical, perhaps multiply by coefficient.Dangle than identical or different with cable wire in the cage side in the counterweight side.In order to compensate the extension of dangle cable wire and compensating rope, on the energy disperser under the counterweight, provide can vertical adjusting structure.Its weak point is: owing to adopt common compensating rope, therefore, noise is bigger, and the life-span is short.

The purpose of this utility model is the elevator that proposes a kind of low noise long life band compensating rope.

The purpose of this utility model is achieved in that is with the elevator of compensating rope to be made up of car, drive wheel, hoist ropes, counterweight, cable wire guide piece, compensating rope etc.Drive hoist ropes by drive wheel, hoist ropes drags car and counterweight edge guide rail separately moves up and down.Be fixed on the also up-and-down movement thereupon of compensating rope below car and the counterweight.Compensating rope is by cable wire, compositions such as the cable wire chain link of the some that promptly links together and metallic cable.The cable wire chain link has corresponding cable wire link hole.Metallic cable is a continuous rope, and it is through among each cable wire link hole.One end of metallic cable passes the back of the cable wire link hole of cable wire chain link to the cable wire chain link from the front of cable wire chain link, the cable wire link hole of passing the cable wire chain link again above next cable wire chain link is below the cable wire chain link, other cable wire chain link can be with reference to the structure that pierces of aforementioned cable wire chain link, until metallic cable being worn to each cable wire link hole of cable wire.Utilize only to relatively rotate between metallic cable or the rigidity wiry restriction cable wire chain link and do not produce mutual bump, thereby eliminate its operation noise.

The utility model has the advantages that: compare with the common compensating rope of same specification that to have a noise low, ratio of performance to price height, long service life, maintenance cost is low, and the intensity height is applied widely etc.

Accompanying drawing of the present utility model:
