Abstract
The utility model relates to a sliding steel rope braking and clipping device of a friction drive hoist and is suitable for the locking of the sliding steel rope in the operating process of the friction drive hoist and the braking of the falling vessels caused by lacking of enough braking force, or is used for the steel rope clipping in the working process of changing the steel ropes. The device comprises a brake cylinder, a back rushing board connected with the brake cylinder, a wedge brake block of the clipping rope, a roller line for ensuring that the wedge brake block can move up and down, a limiting pin for limiting and guiding the wedge brake block, an offsetting spring for automatically offsetting of the wedge brake block, a side stretching plate for guiding a braking device and a limiting block used by the clipping rope. When the braking force of the clipping ropes is not enough resulting that the friction drive hoist can not be stopped, a control system sends a braking signal for controlling the brake cylinder through a hydraulic system, thus leading the hoisting steel ropes of the braking device moving downwards to enclasp and brake; when rope clipping is needed, a braking cylinder rod retracts the braking steel ropes, thus playing a roll of rope clipping. The sliding steel rope braking and clipping device has simple structure and convenient operation and is provided with wide practicability.
