Abstract

The elevator rope braking device of the present invention is characterized by comprising: a fixing frame (9) provided in the vicinity of the main rope (4) for suspending the elevator car; a braking member (10) arranged opposite to the main rope, The braking force is generated by pressing on the main cable; the fixing mechanism (12) fixes the braking member on the above-mentioned fixing frame, and presses the braking member to the main cable, in the state that the braking member is pressed to the main cable When the lower car descends, the fixing mechanism moves the braking member in a direction away from the main rope, and when the car ascends, moves the braking member in a direction approaching the main rope.

Description

technical field [0001] The present invention relates to a rope braking device for an elevator. Background technique [0002] Figure 7 is a schematic configuration diagram showing an example of an elevator with a rope braking device, Figure 8 It is a side view showing a schematic structure of a conventional rope braking device. [0003] exist Figure 7 Among them, a mechanical crossbeam 2 is set above the floor 1 of the machine room, and a winch 3 is arranged above it. The main rope 4 is wound around the pulley of the hoist 3 . A car 5 is suspended from one end of the main rope 4, and the car 5 is guided vertically by a guide rail 6 provided in the hoistway. In addition, a counterweight (not shown) is suspended from the other end of the main rope 4, and the counterweight is guided vertically by a guide rail (not shown) provided in the hoistway. [0004] As a safety device for automatically stopping the car 5 when the speed of the car 5 becomes abnormally high, an emerge...
