Abstract
The invention discloses a component of an elevator landing door system, and particularly relates to an elevator rope sheave which comprises a rope sheave body. An arc rope circular groove is formed in the outer side wall of the rope sheave body, and rope limit convex rings are symmetrically arranged at the opening of the arc rope circular groove. The elevator rope sheave achieves the technical purpose that after the elevator rope sheave and an elevator rope are matched, the elevator rope can not fall out of the arc rope circular groove of the elevator rope sheave under the loosening condition. Matching stability of the elevator rope sheave and the elevator rope is effectively improved, and operation performance of the whole elevator landing door system is improved; meanwhile, due to the fact that a nylon covering layer is arranged on the surface of the arc rope circular groove and the nylon material has good noise reduction performance, noise is avoided when the elevator rope sheave is used in the elevator landing door system.
Description
Technical field
The present invention relates to a kind of parts of elevator landing door system, particularly a kind of elevator rope pulley.
Background technology
Elevator rope pulley is the conventional components in elevator landing door system, and it is main guiding or the draw that plays weight rope or miscellaneous part rope in whole elevator landing door.
The layer door system of closing in whole service of opening or close of elevator landing door system middle level door produces certain vibration effect, and elevator rope pulley in existing elevator landing door system does not carry out spacing structure to being enclosed within its surperficial elevator rope, therefore when elevator landing door system is being that the cooperation moving the time between its elevator rope and elevator rope pulley occurs under relaxation cases, elevator rope is just easily deviate from from elevator rope pulley, affect the normal operation of whole elevator landing door system, while is due to the installation particularity of elevator landing door system, once it goes wrong, follow-up maintenance is just cumbersome.
Summary of the invention
The object of the invention is provides a kind of elevator rope pulley that steadiness is good that coordinates with elevator rope in order to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, the elevator rope pulley that the present invention is designed, comprises rope sheave main body, and the lateral wall of described rope sheave main body is provided with cambered surface rope annular groove, is provided with rope position limiting convex ring in the notch place symmetry of above-mentioned cambered surface rope annular groove.
As preferably, described rope sheave main body comprises base, cover plate and bearing, described base is provided with bearing hole, bearing is placed in bearing hole, cover plate riveted is on base, and hiding a side opening's edge of bearing hole, the opposite side opening's edge periphery of bearing hole is provided with the riveting point of fixed type bearing, is also provided with cambered surface rope annular groove on the lateral wall of described base.In above-mentioned preferred version, rope sheave main body centre bearer is easy for installation, and stabilized structure is good simultaneously.
In order to prevent producing noise after elevator rope and elevator rope pulley contact friction, produce harmful effect to the use of whole elevator landing door system, the rooved face of described cambered surface rope annular groove is provided with nylon overplate.
The elevator roller that the present invention obtains, be provided with rope position limiting convex ring in the notch place of cambered surface rope annular groove symmetry in its structure, even if make snare elevator rope pulley in rope sheave main body occur relaxation cases, it also can not deviate from easily in the cambered surface rope annular groove of above-mentioned rope sheave main body, actv. promoted elevator rope pulley and elevator rope between the two coordinate steadiness, thereby play the drive ability that promotes whole elevator landing door system; Simultaneously owing to being provided with nylon overplate on the rooved face at cambered surface rope annular groove, the concrete well performance muffler of nylon material, the elevator roller that makes to provide in the present invention can not produce noise while use in elevator landing door system.
