Rope braking apparatus

Abstract

The present invention relates to an elevator wire rope braking apparatus, and more particularly, to a rope braking apparatus which prevents partial abrasion of the wire rope while increasing braking efficiency by preventing a deviation in the pressure applied to the wire rope by a pressure plate moving in a straight line to apply pressure to the wire rope. Since the pressure application is based not on a hydraulic method but on a purely mechanical structure using only a spring elastic force, environmental pollution caused by hydraulic oil is prevented and reduced product cost is made possible.

Description

technical field

[0001] The present invention relates to a rope brake device that pressurizes and drives the rope when performing emergency braking in elevators, crane lifts, elevators, etc. that lift and move objects suspended on driving ropes. Background technique

[0002] Elevators used in general buildings use driving ropes to connect the hoist installed in the building and the cage carrying people etc. to realize the up and down movement of the cage by winding and relaxing the driving rope structure.

[0003] Such elevators are provided with braking means for emergency braking of the lift car in case of an emergency.

[0004] The brake device is a structure that blocks the movement of the lift car by grasping the principle of the main rope when emergency braking is required when it is installed on the lift car.

[0005] As the accident prevention standards for elevators have been strengthened, research and development on such rope braking devices has been actively carr...
