Abstract
PURPOSE: To safely pull up a roof and the like to a required height by moving a group of sector wedges for grasping and pulling apart a rope by a vertical motion of a piston up and down by compressed air.
CONSTITUTION: When compressed air is blown into a cylinder 1 through an air path 5, a piston 2 rises while a lower wedge 8a grasps a rope 16, so that the rope 16, so that the rope 16 is pulled up. While the rope 16 is pulled up, the rope 16 is not restricted by an upper wedge 8. When the piston 2 finishes rising and the compressed air is let out of the cylinder, the piston 2 is pushed downward by a force of a spring 14, but as the lower wedge 8a puts no restrictions on the rope 16, the piston 2 descends. All this while the rope 16 is grasped by the upper wedge 8. In one cycle of such operation, the rope 16 is pushed up for a stroke of the piston2. The rope 16 can pull up a hanging load to the required height by repeating this operation.
