Technical Field

The invention relates to the technical field of elevator equipment, in particular to a vibration isolation guide rail bracket device with a circular truncated cone limiting function.

Background

When the elevator car runs in the elevator shaft, the vibration on the guide rail can be transmitted to the shaft wall body through the guide rail bracket. In order to ensure the safety and prevent the guide rail from falling, the traditional guide rail bracket is directly and rigidly connected with the well wall, the vibration at the guide rail side is directly transmitted to the well wall through the guide rail bracket, and the vibration and noise problems in the resident room are caused through the transmission of the building structure. In order to improve the vibration of the guide rail, it is common to add an elastic member between the guide rail bracket and the wall or between the guide rail bracket and the guide rail to reduce the transmission of the normal vibration of the wall. In order to obtain a good vibration isolation effect, it is generally required that the rigidity of the elastic member is as low as possible. However, due to the fact that the elastic element is additionally arranged between the guide rail and the wall body, the guide rail and the wall body are not rigidly connected any more, the guide rail can be displaced and deviated in the up-down direction, the front-back direction and the left-right direction, and if relevant limiting measures are lacked, the guide rail is easily displaced and deviated greatly under the extreme working conditions that the elastic element is burnt out due to ground vibration, safety tongs or fire, the guide rail falls, and personal safety of passengers and safety of building structures are threatened.
