Abstract

The invention discloses a device for reducing vibration of an elevator compensation rope. The device comprises a guide bracket fixed on the ground and a tension device which is arranged on the guide bracket along the vertical direction in a movable manner, wherein the tension device comprises an installation seat and a tension wheel arranged on the installation seat; the compensation rope bypasses the tension wheel downwards; and a buffer capable of supplying upward or downward buffering force to the installation seat is arranged between the installation seat and the guide bracket. When the tension device is vibrated by shake of the compensation rope, the vibration amplitude and the vibration frequency of the tension device can be reduced obviously under the action of the buffering force of the buffer; therefore, the sitting comfortableness in a cage can be improved; furthermore, due to the arrangement of the buffer, the tension force to the compensation rope can be increased, and a tension effect can be enhanced.

Description

Reduce the compensating rope of elevator oscillatory system

Technical field

the present invention relates to reduce the compensating rope of elevator oscillatory system.

Background technology

In prior art, lift car bottom and counterweight bottom are connected with the compensation rope, in running process of elevator; Compensation rope has shake, and is especially more obvious when speed is higher, and the compensation rope ground of beating is severe; When beating when excessive; The compensation rope can pass to the swelling device that is used for tensioner compensation rope with shake, and the vibration meeting of swelling device passes to car through the compensation rope, causes that the passenger is uncomfortable.

Summary of the invention

the purpose of this invention is to provide the device that energy disperser reduces compensating rope of elevator vibration is set.

are for achieving the above object; The technical scheme that the present invention adopts is: reduce the compensating rope of elevator oscillatory system; Comprise the guiding trestle that fixes on the ground, can vertically be arranged on the swelling device on the said guiding trestle movably; This swelling device comprises mount pad, is contained in the expansion tightening wheel on the said mount pad; Said compensation rope is walked around said expansion tightening wheel downwards, and being provided with between said mount pad and the said guiding trestle to provide this mount pad energy disperser of cushion effect up or down.

are as a kind of concrete embodiment; Said energy disperser adopts water bumper; This energy disperser comprises base, with respect to the buffer head that said base can stretch up and down, said base is fixed on the said mount pad, said buffer head is fixed on the said guiding trestle.

are because the utilization of technique scheme; The present invention compared with prior art has advantage: energy disperser is set; Like this when the vibration of compensation rope shake causing swelling device; Under the cushion effect effect of energy disperser, can obviously reduce the Oscillation Amplitude and the frequency of swelling device, thereby improve the comfort that car is taken; Moreover, energy disperser is set, can also increases expanding force, improve the tensioner effect the compensation rope.

Description of drawings

accompanying drawing 1 is a scheme drawing of the present invention.

The specific embodiment

Structure of the present invention is further set forth below in conjunction with accompanying drawing in .

are referring to shown in Figure 1; Reduce the compensating rope of elevator oscillatory system; Comprise the guiding trestle 1 that fixes on the ground, can vertically be arranged on the swelling device 3 on the guiding trestle 1 movably; This swelling device 3 comprises mount pad 31, is contained in the expansion tightening wheel 32 on the mount pad 31, and compensating rope of elevator is walked around expansion tightening wheel 32 downwards, comes tensioner compensation rope through swelling device 3; Be provided with energy disperser 2 between mount pad 31 and the guiding trestle 1, this energy disperser 2 can provide mount pad 31 cushion effect up or down.In Fig. 1, energy disperser 2 adopts water bumpers, and this energy disperser 2 comprises base 21, with respect to the buffer head 22 that base 21 can stretch up and down, and base 21 is fixed on the mount pad 31, and buffer head 22 is fixed on the guiding trestle 1.When 3 vibrations of compensation rope shake causing swelling device, under the cushion effect effect of energy disperser 2, can obviously reduce the Oscillation Amplitude and the frequency of swelling device 3, thereby improve the comfort that car is taken like this; Moreover, energy disperser 2 is set, can also increases expanding force, improve the tensioner effect the compensation rope.
