Abstract
The utility model discloses an elevator chain vibration damping device which comprises a motor support, wherein an elevator motor is arranged on the motor support, two chain wheels are arranged on a rotating shaft of the elevator motor, transmission chains are respectively arranged on the chain wheels, and the transmission chains of the two chain wheels are staggered at a certain distance in the height direction so that the two transmission chains and the chain wheels cannot be meshed and loosened simultaneously. The elevator chain vibration damping device adopts double-chain transmission, and the two chains are staggered by half a pitch in the height direction, so that the two chains and the chain wheel cannot be meshed and loosened simultaneously, and resonance is reduced. Meanwhile, the chain spring clamps are added at the positions with larger vibration, and because the two chains are staggered, meshed and separated, the elasticity of the chain spring clamps can mutually absorb the vibration between the chains, and the vibration and the noise of the chains are effectively reduced.
Description
Technical Field
The utility model relates to the technical field of elevator equipment, in particular to a damping device for preventing an elevator chain from vibrating.
Background
Modern elevators are mainly composed of a traction machine (winch), guide rails, a counterweight, safety devices (such as a speed limiter, a safety clamp, a buffer and the like), a signal control system, a car, a hall door and the like. These parts are installed in the hoistway and machine room of the building, respectively. Usually, a steel wire rope is used for friction transmission, the steel wire rope bypasses a traction sheave, two ends of the steel wire rope are respectively connected with a car and a balance weight, and a motor drives the traction sheave to lift the car. The elevator requires safety and reliability, high conveying efficiency, accurate leveling, comfortable riding and the like. The basic parameters of the elevator mainly include rated load capacity, the number of passengers, rated speed, the overall dimension of the elevator car, the type of the hoistway, and the like.
At present, the elevator mostly adopts chain drive, and it has that the drive ratio is accurate, and transmission efficiency is high, and epaxial atress is less, and compact structure can adapt to multiple abominable operational environment. The defects are that the instantaneous transmission ratio is unstable, the vibration, the impact and the noise are large in the work process, and the vibration, the impact and the noise caused by chain transmission are large in order to be reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an elevator chain vibration damping device with higher transmission effect.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the elevator chain vibration damping device comprises a motor support, an elevator motor is mounted on the motor support, two chain wheels are arranged on a rotating shaft of the elevator motor, transmission chains are respectively arranged on the chain wheels, and the transmission chains of the two chain wheels are staggered at a certain distance in the height direction so that the two transmission chains and the chain wheels cannot be meshed and loosened simultaneously.
Furthermore, a chain spring clamp is arranged between the two transmission chains.
Furthermore, the chain spring clip comprises semi-arc-shaped spring steel and reverse buckle type buckles arranged at two ends of the spring steel.
Furthermore, the two ends of the chain spring clamp are respectively clamped at the middle parts of the outside chain plates of the two transmission chains.
Furthermore, a transmission chain protective cover is arranged on the motor support.
The elevator chain vibration damping device has the advantages of simple structure, small volume, convenience in installation and low cost.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, but the technical solutions in the embodiments of the present invention are not limited to the scope of the present invention.
Referring to fig. 1, 2 and 3, the utility model discloses an elevator chain vibration damping device, which comprises a motor support 3, wherein an elevator motor 1 is installed on the motor support 3, two chain wheels 11 are arranged on a rotating shaft of the elevator motor 1, transmission chains 4 are respectively arranged on the two chain wheels 11, and the transmission chains 4 of the two chain wheels 11 are staggered with each other by a certain distance in the height direction so that the two transmission chains 4 and the chain wheels 11 cannot be meshed and loosened simultaneously.
In one embodiment of the utility model, a chain spring clamp 5 is arranged between the two transmission chains 4; the chain spring clamp 5 comprises a semi-arc spring steel 51 and a back-off type buckle 52 arranged at two end parts of the spring steel 51; specifically, the back-off buckles 51 at the two ends of the chain spring clamp 5 respectively clamp the middle parts of the outside link plates of the two transmission chains 11.
In yet another embodiment of the utility model, a cover for the drive chain guard 2 is provided on the motor bracket 3.
The elevator chain vibration damping device adopts double-chain transmission, and the two chains are staggered by half a pitch in the height direction, so that the two chains and the chain wheel cannot be meshed and loosened simultaneously, and resonance is reduced. Simultaneously, a chain spring clamp is added at the position with larger vibration, the chain spring clamp is made of spring steel, two ends of the chain spring clamp are designed into reverse buckle type buckles, the chain outer side chain plates can be clamped once when the chain spring clamp is installed, the middle parts of the outer side chain plates of one chain are clamped at two ends respectively, and after the two chains are connected and fixed through the chain spring clamp, the two chains are meshed and separated in a staggered mode, so that the elasticity of the chain spring clamp can absorb the vibration between the chains mutually, and the vibration and the noise of the chains are effectively reduced.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the utility model.
