Abstract

The invention provides an elevator main suspension line shake preventing apparatus which can faithfully prevent the shakes of a main suspension line with a simple structure and conveniently perform setting operations. The apparatus comprises a car side shake preventor used for preventing shakes of the main suspension line on the elevator car side when a drive pulley with the main suspension line wound serves as a reference; a heavy side shake preventor used for preventing shakes of the main suspension line on the heavy side when the drive pulley serves as the reference; connecting slings connecting the shake preventors and having shake preventor rope wheels connected with slings wound thereon. The weights of the shake preventors are greater than the total weight of the shake preventor and the connecting slings. The shake preventors rise and fall inside an elevating channel in a way to not contact each other. When the shake preventors interfere with counterweights during a rising process, the shake preventors are pushed upwards so that the positions of the shake preventors are lowered.

Description

technical field [0001] The present invention relates to an elevator main rope sway restraining device for restraining the sway of a main rope suspending an elevator car and a counterweight. Background technique [0002] As the prior art related to the above-mentioned anti-sway prevention of the main rope for the elevator, the elevator rope sway prevention device disclosed by Patent Document 1 can be cited, which can prevent the noise when the elevator car is raised and lowered, and can reliably Prevent the main sling and compensating sling from swaying. [0003] prior art literature [0004] patent documents [0005] Patent Document 1 Japanese Patent Application Laid-Open No. 2007-22673 Contents of the invention [0006] The problem to be solved by the invention [0007] In the technology disclosed in the above-mentioned Patent Document 1, the lifting speed of the sway arresting body for suppressing swaying of the main rope is set to half the speed of the elevator car ...
