Problems solved by technology

[0003] The opening or closing of the landing door in the elevator landing door system will have a certain vibration effect on the entire operating landing door system, and the elevator sheave in the existing elevator landing door system does not limit the elevator rope on its surface. Therefore, when the elevator landing door system is running at a certain time, when the cooperation between the elevator rope and the elevator sheave becomes loose, the elevator rope will easily come out of the elevator sheave, which will affect the normal operation of the entire elevator landing door system. At the same time, due to the particularity of the installation of the elevator landing door system, once there is a problem, the follow-up maintenance will be more troublesome

Embodiment 1

[0015] Such as figure 1 As shown, the elevator sheave provided in this embodiment includes a sheave main body 1, an arc-shaped rope ring groove 2 is provided on the outer wall of the sheave main body 1, and the notch of the above-mentioned arc-surface rope ring groove 2 2-1 is symmetrically provided with a rope limiting protruding ring 3 .

Embodiment 2

[0017] Such as figure 2 As shown, the general structure of the elevator sheave provided by this embodiment is consistent with that of Embodiment 1, but the main body 1 of the sheave described in this embodiment specifically includes a base 4, a cover plate 5 and a bearing 6, and the base 4 There is a bearing hole 4-1 on the top, the bearing 6 is placed in the bearing hole 4-1, the cover plate 5 is riveted on the base 4, and covers the edge of one side of the bearing hole 4-1, and the other side of the bearing hole 4-1 A riveting point 7 for a fixed bearing 6 is provided along the periphery of one side opening, and an arc-shaped rope ring groove 2 is also provided on the outer wall of the base 4 . In the above preferred solution, the bearing 6 in the sheave main body 1 is easy to install and has good structural stability.

Embodiment 3

[0019] The general structure of the elevator sheave provided in this embodiment is the same as that of Embodiment 2, but in order to prevent the elevator ropes from producing noise after contacting and rubbing the elevator sheave, it will have a negative impact on the use of the entire elevator landing door system, such as image 3 As shown, the groove surface 2-2 of the curved rope loop groove 2 in this embodiment is provided with a nylon covering layer 8 .

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 [0001] The invention relates to a component of an elevator landing door system, in particular to an elevator sheave. Background technique [0002] The elevator sheave is a conventional component in the elevator landing door system, and it mainly guides or pulls the lifting hammer rope or other component ropes in the entire elevator landing door device. [0003] The opening or closing of the landing door in the elevator landing door system will have a certain vibration effect on the entire operating landing door system, and the elevator sheave in the existing elevator landing door system does not limit the elevator rope on its surface. Therefore, when the elevator landing door system is running at a certain time, when the cooperation between the elevator rope and the elevator sheave becomes loose, the elevator rope will easily come out of the elevator sheave, which will affect the normal operation of the entire elevator landing door system. At the same time, ...
