Problems solved by technology

Elevator noise is different from ordinary noise. Because it is low-frequency noise pollution accompanied by relatively large vibrations, conventional measures such as sound insulation, sound absorption, or even double concrete walls in the well wall or the owner's room cannot effectively solve the noise. transfer

Embodiment Construction

[0019] In the current guide rail fixing installation process in the elevator industry, all elevator manufacturers use steel structure guide rail brackets to directly fix the elevator guide rails. Since this rigid guide rail fixing method does not have any vibration reduction, it leads to vibration of the elevator guide rails. It is directly transmitted to the owner's room through the connection of this bracket. The present invention adds an elastic vibration reduction and noise reduction device between the elevator guide rail and the wall, so that the vibration of the guide rail is absorbed by the vibration reduction and noise reduction device, and then transmitted to the wall, so as to eliminate the low frequency vibration noise caused by the elevator vibration the goal of.

[0020] As the first embodiment of the present invention, the elastic damping device includes a rectangular parallelepiped vibration-damping fixed box 20, the lengths of both ends of the steel plate on th...

Abstract

The invention discloses a vibration-reducing and noise-reducing device for an elevator guiding track, comprising an elevator guiding track and a fixing board for fixing the guiding track; being characterized in that a flexible vibration-reducing device is provided between the guiding track and the wall body; the flexible vibration-reducing device is provided with a flexible vibration-reducing piece; the guiding track fixing board is directly connected to the vibration-reducing piece via a vibration-reducing supporting part; the flexible vibration-reducing piece is enveloped in a case; the vibration-reducing fixing case is fixed on the well wall body via the bolts. The invention reduces the vibration and noise via adding the flexible vibration-reducing device between the elevator guiding track and the wall; after the vibration of the guiding track is absorbed by the device, the vibration is delivered to the wall, which can completely solve the low frequency vibration noise caused by the guiding track vibration and giving the tenements a healthy and comfortable living environment.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator guide rail vibration and noise reduction device that can effectively absorb and reduce low-frequency vibration noise generated by sliding friction of guide rails when the elevator runs at high speed. Background technique [0002] In the case of the rapid development of real estate in my country, many developers have neglected the influence of the vibration noise of the elevator guide rails on the interior due to lack of experience in architectural design, the beauty of the building itself and the saving of public areas in architectural design. The wall of the hoistway and the wall of the living room are often designed as the same common wall in the design. The elevator car and the counterweight slide in the elevator rail guide, and the guide rail is directly fixed on the common wall between the hoistway and the owner's room through the bracket. The rigid connection b...
