Abstract

The present invention relates to an elevator rope sway control device, which comprises a rope end bar arranged on a plurality of elevator ropes, a sway detection unit, a controller, and a rope tension controller arranged on the rope end bar. The rope tension controller includes a displacement sensor, a hydraulic cylinder group, a spring assembly, a hydraulic pump, and a valve; the hydraulic cylinder group includes two groups of hydraulic cylinders, and a check valve is arranged between the two groups of hydraulic cylinders; the swing detection unit and the control The controller is connected with the hydraulic pump, and the hydraulic pump controls the hydraulic cylinder group to apply force to the spring assembly through the valve. The excitation of the natural frequency of the plurality of ropes is mitigated by the device, so as to prevent the plurality of ropes from swaying and resonating with the building, causing damage to other components or maintaining the personal safety of passengers.

Description

technical field [0001] The present invention relates to an elevator installation. More specifically, it relates to an elevator rope sway control device. Background technique [0002] During the use of elevators, if encountering strong winds, earthquakes, etc., buildings tend to sway laterally. As the building sways, the lateral motion of the building is typically translated into lateral motion of the ropes of the elevator system installed in the building. The lateral movement of the ropes can cause collisions, noise, wear and damage to elevator system equipment and / or buildings. [0003] In the prior art, several methods are used to alleviate the rope sway problem. One is to use a mechanical device to restrain the rope to limit rope sway. This mechanical structure may effectively limit the lateral swing of the rope, but the cost is relatively high and it takes up a large space in the hoistway. Another approach is to limit elevator car travel during periods of building s...
