Description

Technical Field

[0001] The utility model relates to the technical field of elevator maintenance, in particular to an adjustment device for an elevator wire rope. Background Art

[0002] As the elevator operates, the length of the wire ropes between the car and counterweight constantly changes, causing the tension on both sides of the traction sheave to change at any time. To reduce the tension difference caused by the varying lengths of the wire ropes on both sides of the traction sheave, a common method is to install compensating chains, ropes, or cables between the counterweight and the bottom of the car. This balances the mass of the wire ropes on both sides of the car and counterweight, reducing the tension difference and improving traction efficiency. When the elevator is running at high speeds, compensating ropes are mainly used for compensation.

[0003] However, since the wire rope will stretch to a certain extent under the action of gravity, the elongation of the wire rope will cause the elevator to experience unstable phenomena such as shaking and trembling during operation. In addition, the existing elevator wire rope adjustment device is not designed with a shock-absorbing mechanism, which causes the adjustment device to vibrate up and down significantly when the elevator stops in an emergency. When the vibration spreads to the elevator car, it will cause a safety hazard. Utility Model Content
