Guide component and guide device

Abstract

The invention discloses a guide component and a guide device, and belongs to the technical field of elevators. The guide component comprises a first roller, a first mounting base, a second roller, a second mounting base, a swing arm of which the two ends are provided with a first sliding rod and a second sliding rod symmetrically, an actuator and a connecting device fixedly connected with the swing arm, and the guide device comprises a plurality of guide components, guide mounting plates and guide rails. The guide device has the beneficial effects that the distance between the rollers in the guide component can be regulated through the guide device according to the current running speed and current inherent frequency of an elevator body, so that the horizontal vibration of the elevator body at different motion states and inherent frequencies due to the defects of the guide rails is eliminated.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a guide assembly and a guide device. Background technique [0002] When the elevator moves in the vertical direction, it usually needs a corresponding guide device to ensure the comfort of the user. The guide rails in the guide device are usually spliced, and there will inevitably be steps out of tolerance at the joints of the guide rails, and Since the working surface of the guide rail often has problems such as local defects, local distortions and excessive spacing, this will further aggravate the vibration of the elevator car in the horizontal direction. With the continuous increase of building floors in recent years, the running distance and running speed of the supporting elevators are increasing accordingly, and the guide rail problem has an increasing impact on the vibration of the elevator car. [0003] The elevator is usually divided into three stages during its opera...

AI Technical Summary

Problems solved by technology

When the elevator passes through the same guide rail unevenness at different operating speeds and / or different natural frequencies, the vibrations will be different. The guide shoes that can reduce the horizontal vibration of the elevator in the elevator constant speed stage may be parallel in the acceleration and deceleration stage of the elevator. The same vibration reduction effect cannot be achieved. The guide shoes that can reduce the horizontal vibration of the elevator when the elevator is fully loaded may not achieve the same vibration reduction effect when the elevator is unloaded
