In this case, if gondola stop at destination time there is the abnormal running that slides or to fall etc., then the control part (omitting diagram) of elevator responds to faulty condition as above, carries out rope brake device 200 is run by the control of collecting the control part of this information.
Namely, when there is the strange phenomenies such as gondola fault, control part is responded to this phenomenon and is inputted information, according to inputted information, control part cuts off the power supply being fed to electromagnetic valve 244d, then electromagnetic valve 244d is opened, and the air being simultaneously stored at air bellow 240 is fed to the pneumatics room 232 of cylinder 231 by air supply pipe 244c.
So, while air is fed to the pneumatics room 232 of described cylinder 231, the cylinder rod 244 that coupling is fixed on the pneumatics room 232 of cylinder 231 is stretched out from pneumatics room 232.
Now, when described cylinder rod 244 is stretched out from the pneumatics room 232 of cylinder 231, the axis of guide 260 that coupling is fixed on the coupling aperture 246a that the flange 246 of cylinder rod 244 is formed retreats along the pilot hole 234 of cylinder 231, when the axis of guide 260 retreats along pilot hole 234, the state that elastomeric element 266 is pressed retreats, along with the retrogressing of the described axis of guide 260, the movable cushion 250 that coupling is fixed on the axis of guide 234 retreats, and then makes the axis of guide 260 and air bellow 240 retreat and touch limit switch 274.
Therefore, as shown in Figure 6 b, described cylinder rod 244 from cylinder 231 stretch out and movable cushion 250 by the axis of guide 260 action, now, the rope W of pressing between fixed bolster 236 and movable cushion 250 makes it lock, and the axis of guide 260 touches the operation that limit switch 274 stops elevator simultaneously.

So, after completing the inspection of elevator, open button 279 under the state stopping described gondola, to remove the lock-out state of rope brake device 200 with described identical mode, thus gondola can normally run.
Owing to there is the strange phenomenies such as gondola fault, and rope brake device 200 is when running to make gondola move under the locked state of rope W, manual operation electromagnetic valve 244d discharges the pressurized air of air bellow 240, now by the elastic force of elastomeric element 266, movable cushion 250 makes rope W depart from from lock-out state, thus gondola can be made to run.
And coupling can be utilized to be fixed on the adjustment inclination bolt 218 of circular arc elongated hole 214 to adjust the leaning angle of rope brake device 200, and circular arc elongated hole 214 is formed in the sidepiece of described fixed mount 210.
Namely, when unclamping described adjustment inclination bolt 218, the adjustment inclination bolt 218 that screw is fixed on bracing frame 220 can make bracing frame 220 be that benchmark moves and after being adjusted to the leaning angle meeting rope W freely with bolt of rear end plate 216 in elongated hole 214, tighten adjustment inclination bolt 218, then complete the tilt adjustments of rope brake device 200.
On the one hand, when being moved by the gondola of the elevator of rope brake device 200 run-stopping status, if open safety valve 276, then the air of air bellow 240 is discharged and air pressure decline, thus removes the lock-out state of rope W and elevator can be made to run.
Above, describe the preferred embodiment according to rope brake device for elevator of the present invention, but the present invention is not limited thereto, can carry out various distortion in the scope of right and detailed description of the invention and appended drawing to implement, naturally these variant embodiment also should belong to interest field of the present invention.
