Damping device for elevator guide rail

Abstract

The invention discloses an elevator guide rail damping device. The elevator guide rail damping device comprises a wall connecting frame, a guide rail support connecting cover and an elastic damping cushion installed in a box structure formed between the wall connecting frame and the guide rail support connecting cover. The guide rail support connecting cover and the wall connecting frame are screwed by a pair of first bolts and a pair of second bolts to be fixed to pre-buried nuts in the elastic damping cushion respectively, and the first bolts are perpendicular to the second bolts. A third bolt penetrates through the guide rail support connecting cover, the elastic damping cushion and the wall connecting frame and is screwed to the nut fixed to the wall connecting frame, and the head of the third bolt is provided with an elastic damping washer. The elevator guide rail damping device can absorb vibration of guide rails of an elevator in an all-around mode, and the damping effect is good. When the elastic damping cushion is aged and deform and a clearance exists between the contact face of the elastic damping cushion and the contact face of the box structure, the elastic damping washer can deform to a certain degree to fill the clearance, the serious reducing of the damping effect is avoided, the damping effect of the damping device is reliably guaranteed, and the service life of the damping device is prolonged.

Description

technical field [0001] The invention relates to a damping device, in particular to a damping device for an elevator guide rail. Background technique [0002] In order to reduce the vibration and noise of the elevator running, a shock-absorbing and noise-reducing device needs to be installed between the elevator guide rail bracket and the shaft wall. The vibration generated by the elevator operation is not directly transmitted to the elevator shaft wall, but first passes through the shock and noise reduction device, absorbs the vibration, and then reaches the elevator shaft wall. Through the absorption of vibration energy by the shock and noise reduction device, the vibration and noise of the shock and noise reduction device can be better eliminated or alleviated, thereby avoiding adverse effects on buildings and residents near the shaft wall. [0003] Existing elevator guide rail shock-absorbing devices usually include a wall mount, a guide rail bracket connection cover and...

AI Technical Summary

Problems solved by technology

No matter which kind of elevator guide rail damping device is mentioned above, it cannot have excellent damping performance in front and rear, up and down, left and right, and all directions at the same time.

[0004] In addition, the elastic shock-absorbing pads of the above-mentioned existing elevator guide rail shock-absorbing devices are usually bonded in the storage tank by glue. There will be a certain gap between the connecting plate and the vibration-transmitting plate, so that when the elevator guide rail vibrates, the connecting handle cannot directly contact the elastic shock-absorbing pad, or the elastic shock-absorbing pad cannot directly connect with the guide rail bracket and the box formed by the combined wall frame The wall of the structure is in contact, which greatly affects the effect of shock absorption and noise reduction, and may even generate additional noise, which cannot achieve the ideal use effect
