Vibration reduction support for elevator guide rail

Technical Field

The utility model belongs to the technical field of vibration reduction devices, and particularly relates to a vibration reduction support for an elevator guide rail.

Background

When the elevator car moves up and down, vibration is generated and transmitted to an adjacent living room through the guide shoes, the guide wheels, the guide rails and the shaft wall, so that vibration in the living room and noise caused by the vibration are generated. In recent years, the requirements of people on the quality of life are rapidly improved, and the indoor vibration and noise caused by the operation of an elevator car are gradually paid attention to by people. Meanwhile, due to the shortage of urban land, high-rise buildings serving as residential buildings in cities are continuously increased, and elevators are essential vertical transportation tools for the high-rise buildings, so that the noise problem caused by elevator complaints of residents is more frequent. The reduction or elimination of the vibration and noise in the house caused by the running of the elevator car is of great significance.

At present, common methods for reducing vibration and noise in a neighboring room caused by the operation of an elevator car are as follows: the vibration damping method can reduce the vibration of the elevator car, but cannot prevent the vibration of the elevator car from being transmitted into a room; the vibration of the guide rail transmitted from the guide shoe of the elevator car is reduced by using the rubber guide wheel, and the vibration reduction method can prevent high-frequency vibration from being transmitted, but can not effectively reduce the transmission of low-frequency vibration into a room; the surface of the wall of the elevator shaft is paved with sound-absorbing materials, so that the noise transmitted into the adjacent rooms through the wall of the elevator shaft is reduced, and the noise reduction method only can block the air sound transmission and cannot eliminate the vibration and the noise transmitted into the rooms through solids.

Detailed Description

For a better understanding of the present invention, reference is made to the following description taken in conjunction with the accompanying drawings and examples.

As shown in fig. 1, a damping support for elevator guide rail, including base 1, guide rail support 2, sliding support 3, spring stopper 4, electromagnetic damper 5 and active cell 6, the base left side passes through high strength bolted connection with elevator well wall 7, inside is equipped with damping chamber and sliding chamber from a left side to the right side in proper order, the junction is equipped with the perforating hole, electromagnetic damper installs in the damping chamber, sliding support is fixed in on the inner wall in sliding chamber, the active cell is located in the perforating hole, both ends head stretches into damping chamber and sliding chamber respectively, the guide rail support is T type plate structure, the left end stretches into the sliding chamber and is connected with the active cell, the right-hand member passes through high strength bolted connection with elevator guide rail 8, the spring stopper is located between base and the guide rail support, both ends are connected with the terminal surface that corresponds respectively.

The electromagnetic damper comprises a shell 9, a conductor tube 10, a permanent magnet 11 and an iron block 12, wherein the shell is embedded in a damping cavity, the conductor tube is embedded in the shell, and the permanent magnet and the iron block are arranged in the conductor tube at intervals. When the elevator guide rail vibrates in the horizontal direction, the permanent magnet inside the electromagnetic damper can be driven to move, according to the electromagnetic induction theorem, the relative motion between the permanent magnet in the electromagnetic damper and the conductive material in the conductor pipe can induce eddy currents in the conductive material and excite an induction magnetic field, and the effect of the induction magnetic field can block the relative motion between the conductive material and a main magnetic field, namely, damping force is generated on the moving magnet.

The spring limiter is horizontally arranged, and two ends of the spring limiter are respectively connected with the base and the guide rail support. When the horizontal displacement of the guide rail support does not reach the set limit value, the spring limiter can be stretched freely and acts as a common spring; when the horizontal displacement of the guide rail support is overlarge, the spring limiter can not stretch out and draw back, and the horizontal movement of the guide rail support is forcibly stopped. Therefore, the spring limiter can effectively prevent the guide rail support from excessively displacing horizontally.
