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 may be prevented and product cost may be reduced.
Claims11
A rope braking apparatus comprising:
- an installation body comprising a wire rope positioned on a back surface of the installation body, the wire rope being connected to a lifted/lowered object;
- a driving unit comprising a driving motor installed on the installation body, a transfer block unit installed to be movable upwards/downwards while being connected to the driving motor, and elastic members installed on the transfer block unit;
- a pressurization unit comprising a movable unit installed on the installation body so as to be movable forwards/backwards along a straight line while contacting the transfer block unit and a pressurization plate positioned to face the installation body, with the wire rope interposed, while being connected to the movable unit;
- and
- a movement control unit configured to control a movement of the pressurization unit and including a solenoid unit.
