- the drive unit 53 shown as a cross section in FIGS. 2 and 3 has a bearing 1 b of the rotating shaft 1 a of the sheave 1 similarly to the king pins 5 fl and 5 f 2 (FIG. 4). (See the left bearing).
- the drive section 53 includes a solenoid 5b and a plunger 5d driven by turning on and off the current to the solenoid 5b.
- the lower end of the plunger 5d is connected to a brake shoe 50.
- 5 m pin is provided.
- the pin 5m fits into a movable support hole 5n formed in the main body 50a of the brake shoe portion 50, is connected to the brake shoe portion 50, and drives the brake shoe portion 50.
- the brake shoe part 50 is suspended from the pin 5 m at the lower end of the plunger 5d, and abuts on a position separated from the inner wall of the sheave 1 shown in FIG. 2 and the inner wall of the sheave 1 shown in FIG. Moved between positions. Then, according to the shapes of the movable support holes 5 k 1, 5 k 2 and the movable support holes 5 n described later, the movable support holes 5 k 1 and 5 n can be inclined at predetermined angles to both sides with respect to a vertical center line passing through the rotation axis 1 a.

- a speed detector 107 provided in the hoisting machine 105 performs return control on the elevating speed.
- the service brake 113 is operated to lock the rotation of the hoist 105.
- the speed abnormality detecting means 109 obtains the control command state for the car 3 from the elevator control device 101, and determines the actual car movement (speed, direction) at that time of the hoisting machine 105. By checking the rotation status from the detection signal of the speed detector 107, it is monitored whether a speed error (including direction) has occurred.
- the detecting means 109 instructs the emergency brake driving means 111 to drive the emergency brake 5.
- the emergency brake driving means 1 1 1 always cuts off the current supply to the solenoid 5b of the driving section 53 of the emergency brake 5 which has been supplied.
- the brake shoe part 50 that had been pulled up by the drive unit 53 has the lower brake shoe 5a attached to the inner wall of the outer frame of the sheave 1 as shown in FIG. Lower to the abutment position.

- the speed abnormality detecting means 109 detects the abnormal speed, and the emergency brake driving means 1 1 1 1 moves to the solenoid 5b.
- the brakes 50 descends due to gravity, and the brakes 5a below the brakes 5a are pressed against the sheave 1, and the wedge effect causes the brakes 1b to rotate as the sheave 1 rotates.
- Part 50, especially the part on the spring mechanism 51 side, is caught between the sheave 1 and the king pin 5f1, and the spring force of the coil spring 5e1 and the braking force generated by the rake 1a are balanced. Move until you do.
- the coil spring 5e1 is further compressed from the normal state by a predetermined amount to generate a constant pressing force, thereby causing a brake between the brake shoe 5a and the sheave 1 Generate force. Therefore, the ascending car 3 is decelerated and stopped with a constant braking force regardless of the speed.
- the emergency brake 5 has a symmetrical structure on the left and right of the center line, the same operation and effect are exerted even when the car 3 descends. Can be.
- the abnormal speed of the car 3 in the upward direction is detected and the car is stopped, but the emergency brake 5 applies the brakes 5a to the inner wall of the sheave 1 when the car 3 is stopped.
- the contact makes it possible to prevent not only abnormal speeds but also abnormal rise and fall of the car 3 when passengers get on and off with the car stopped.
- the emergency brake according to the present invention can be applied not only to an elevator but also to an emergency brake of various rotating devices, and a similar improvement in safety can be achieved.
