Elevator door hanging structure

Abstract

The invention belongs to the technical field of elevator manufacture, and discloses an elevator door hanging structure which comprises a hanger and a guide rail shaft, wherein the hanger is used for being connected with an elevator door; the guide rail shaft is installed on a header plate of the door through a bracket; the hanger is provided with a through hole; the guide rail shaft passes throughthe through hole to enable the hanger to be sleeved on the guide rail shaft; and the inner wall of the through hole is provided with a plurality of rolling bodies which are in contact with the guiderail shaft. By using the structure, the invention has the following advantages: (1) the elevator door can move smoothly when being opened and closed, and has small friction force and noise; (2) the door hanging structure is compact and small in volume, and can simplify and reduce the whole volume of an elevator door system; and (3) the elevator door can be effectively prevented form derailing, andsimultaneously, because the gap between the guide rail and the hanger is small, the elevator door can be effectively prevented from swinging.

Description

technical field [0001] The invention belongs to the technical field of elevator manufacturing, and in particular relates to an elevator door hanging structure. Background technique [0002] The elevator door system is an important component of the elevator. Such as figure 1 and figure 2 As shown, the structure of the existing elevator door system for hanging the elevator door is usually: the elevator door 1 is fixed on the door hanging part 2, the door hanging roller 4 and the door limit wheel 5 are fixed on the door hanging part 2, and the guide rail 3 Between the door hanging roller 4 and the door limit wheel 5; driven by external force, the door hanging roller 4 rolls on the guide rail 3, driving the door hanging part 2 to move together with the elevator door 1 fixed thereon. The door limit wheel 5 then guarantees that the door hanger does not break away from the guide rail 3. However, the existing elevator door hanging structure has a relatively large external dimen...

AI Technical Summary

Problems solved by technology

However, the existing elevator door hanging structure has a relatively large external dimension as a whole; and, since the rollers roll on the guide rail, there is a certain friction force between the two, and certain noises can be generated; meanwhile, the guide rail and the elevator There is a certain gap between the door limit wheels, so when the elevator door reciprocates, the elevator door will shake up and down.
