Abstract

The rope brake device for an elevator comprises: a fixed frame 9 installed near a main rope 4 hanging an elevator car; a braking member 10 opposed to the main rope and generating a braking force whenpressed by the main rope; a mounting mechanism 12 mounting the braking member to the fixed frame and pressing the braking member against the main chain. The mounting mechanism moves the braking memberin a direction separated from the main rope in moving down of the car with a state where the braking member is pressed against the main rope, and moves the braking member in a direction getting closer to the main rope in moving up of the car.

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...
