- a pair of upper car guide shrouds 5 that engage with the car guide rails 4 are mounted on the upper part of the car 2.
- a pair of emergency stop devices 6 are provided at the lower portion of the force cage 2 to emergency stop the cage 2 by mechanically engaging with the force guide rail 4.
- a driving device (lifting machine) 7 for raising and lowering the force 2 and the counterweight 3 is installed.
- the drive device 7 includes a motor unit, a drive sheave 8 that is rotated by the motor unit, and a brake unit that brakes the rotation of the drive sheave 8.
- an electromagnetic brake device is used as the brake unit.
- the brake shoe is pressed against the braking surface by the spring force of the braking spring to brake the rotation of the drive sheave 8, and the brake force is released by exciting the electromagnet. , Braking is released.
- a deflecting wheel 9 is arranged in the vicinity of the driving device 7.
- a plurality of main ropes 10 (only one is shown in the figure) are wound around the drive sheave 8 and the deflector 9.
- a car 2 is suspended from the first end 10 a of the main rope 10.
- a counterweight 3 is suspended from the second end 10 b of the main rope 10. That is, the force 2 and the counterweight 3 are suspended in the hoistway 1 by the main rope 10 in a 1: 1 roving manner.
- a speed governor 11 for detecting the speed of the force 2 is installed at the upper part of the hoistway 1.
- a governor rope 12 is wound around the governor sheave of the governor 11.
- a governor wheel 13 is arranged in the lower part of the hoistway 1, a governor wheel 13 is arranged.
- the governor rope 13 is wound around the lower end of the governor rope 12.
- a pull-up bar 14 for operating the emergency stop device 6 is pulled out.
- the pull-up bars 14 are connected to each other via a link mechanism 15. Both ends of the governor rope 12 are connected to the link mechanism 15. For this reason, the governor rope 12 is circulated and moved as the force 2 is raised and lowered, and the governor sheave of the governor 11 is rotated at a speed corresponding to the traveling speed of the force 2.
- FIG. 2 is a side view showing the safety device 6 of FIG.
- An emergency stop frame 31 is fixed to the lower portion of the force 2.
- the emergency stop frame 31 is provided with an emergency stop housing part (or emergency stop mounting part) 31a and a guide shoe housing part (or guide shoe mounting part) 31b. That is, the emergency stop accommodating portion 3 la and the guide shoe accommodating portion 3 lb are integrally formed.
- the emergency stop frame 31 is made of, for example, a steel plate.
- the guide shoe housing part 31b is provided at the lower part of the emergency stop housing part 3la.
- An emergency stop main body 32 is mounted and accommodated in the emergency stop accommodating portion 31a.
- the emergency stop main body 32 includes a pair of taper members 33, a plurality of pressing springs 34 provided between the taper member 33 and the emergency stop accommodating portion 31a, and a pair of braking pieces (wedge members) 35 facing the taper member 33. And a plurality of rollers 36 interposed between the taper member 33 and the braking piece 35.
- the components of the emergency stop body 32 are arranged symmetrically around the car guide rail 4.
- Each taper member 33 is provided with a tapered surface 33a that faces the car guide rail 4 and whose distance from the car guide rail 4 decreases as it goes upward.
- Each braking piece 35 faces the tapered surface 33a.
- Each braking piece 35 is provided with a braking surface 35a facing the force guide rail 4.
- a pulling rod 14 is connected to each braking piece 35.
- a pair of lower car guide shoes (sliding guide shoes) 39 are attached and housed inside the guide shoe housing part 31b.
- the lower car guide shoe 39 is arranged symmetrically around the car guide rail 4.
- the car 2 is moved up and down in the hoistway 1 by being guided by the car guide rail 4 when the upper car guide show 5 and the lower car guide show 39 are engaged with the car guide rail 4.
- the emergency stop main body 32 and the lower car guide shoe 39 are installed in the emergency stop frame 31 in advance in the factory.
- the emergency stop main body 32 is attached to the emergency stop accommodating portion 31a so that the distance to the center force braking surface 35a of the emergency stop frame 31 is equal on both sides of the center, and at the same time the center of the emergency stop frame 31 and the lower car guide
- the car guide shoe 39 is mounted in the guide shoe housing 3 lb so that the distance to the guide surface of 39 is equal on both sides of the center.
- the emergency stop frame 31 is attached to the car 2 while adjusting only the left and right clearances between the guide surface of the car guide shoe 39 and the car guide rail 4, the distance between the braking surface 35a and the car guide rail 4 The left and right gaps are automatically the same.
- the emergency stop body 32 and the cage guide 39 are attached to the common emergency stop frame 31, so that the position adjustment work at the installation site can be greatly reduced. The efficiency of installation work can be improved. Further, since the lower car guide shoe 39 and the braking piece 35 are separate members, the replacement force of the lower force guide shoe 39 does not increase.
- the sliding guide show is shown as the lower car guide show 39, but the car guide show may be a roller guide show.
- a one-handed type that presses the braking piece only on one side of the force-carrying guide rail 4 that shows a double-handed type emergency stop body 32 that sandwiches the car guide rail 4 with a pair of braking pieces 35 Use the emergency stop body.
- the emergency stop device 6 is operated when the second overspeed of the force 2 is mechanically detected by the governor 11 is shown. May be detected electrically (for example, by a calculation process by a computer) and the emergency stop device may be operated.
- the emergency stop main body may have an actuator (for example, an electromagnetic actuator) that is driven in response to an input of an electrical activation signal.
- the force roving method showing an elevator apparatus in which the force 2 and the counterweight 3 are suspended by the 1: 1 roving method is not limited to this, for example, 2 : 1 roving method!
