- an intrusion prevention tool 20 for preventing falling objects from entering the sheave is attached near the entrance of the sheave of the rope 2.
- An object of the present invention is to solve the above-described problems, and it is possible to reduce an installation space of an intrusion prevention device without being affected by a large change in a swing angle of a mouth.
- the purpose is to obtain an overnight device.
- the elevator apparatus includes: a hoistway that lifts and lowers a hoistway; a hoistway; a counterweight that moves up and down in conjunction with the car; and the car and the counterweight are suspended in the hoistway.
- FIG. 1 is a front view of an intrusion prevention device of the elevator apparatus according to Embodiment 1 of the present invention.
- FIG. 2 is a right side view of the intrusion prevention device of FIG.
- FIG. 3 is a diagram showing a use mode of the intrusion prevention device of FIG. 1,
- Figure 4 is a right side view of the intrusion prevention device of Figure 3,
- FIG. 5 is a diagram showing the first contact piece of FIG. 4 being removed from the intrusion prevention device
- FIG. 6 is a diagram showing the use of the intrusion prevention device when the elevator device is driven
- Figure 7 is an enlarged view of the intrusion prevention device of Figure 6,
- Figure 8 is a right side view of the intrusion prevention device of Figure 7,
- FIG. 9 is a diagram showing another use mode of the intrusion prevention device of FIG. 1,
- FIG. 10 is a front view of the intrusion prevention device of the conventional elevator apparatus. BEST MODE FOR CARRYING OUT THE INVENTION
- FIG. 1 is a front view of an intrusion prevention device of an elevator apparatus according to Embodiment 1 of the present invention
- FIG. 2 is a right side view of the intrusion prevention device of FIG. 1
- FIG. 4 is a right side view of the intrusion prevention device of Fig. 3
- Fig. 5 is a diagram showing a state where the first contact piece of Fig. 4 is removed from the intrusion prevention device
- Fig. 6 is a diagram when the elevator device is driven.
- 7 is an enlarged view of the intrusion prevention device of FIG. 6, and
- FIG. 8 is a right side view of the intrusion prevention device of FIG.
- This elevator system includes a car (not shown) that moves up and down the hoistway, a counterweight (not shown) that moves up and down in conjunction with the car in the hoistway, and a car and counterweight that moves up and down. It has a mouthpiece 2 suspended in the road, a sheave 3 around which the rope 2 is wound, and an electric motor which is a driving device for driving the sheave 3, and the electric motor is driven through the rope 2
- the hoisting machine 1 for raising and lowering the car and the counterweight, and the mouthpiece 2 are provided both near the entrance to the sheave 3 for the sheave 3 and can be adjusted in angle to the rope 2 so that the sheave 3 from the entrance to the rope 2
- An intrusion prevention device 4 for preventing a falling object from entering between the rope 2 and the rope 2 is provided.
- the intrusion prevention device 4 includes a bracket 6 fixed to a mounting base 5 which is a mounting member fixed to the hoisting machine 1 with a first fastener 7, a holding plate 22, a bracket 6 and a holding plate 2. 2 and a first contact piece 8 and a second contact piece 30 fixed by a second fastener 24.
- the first contact piece 8 and the second contact piece 30 are made of urethane which is an elastic body.
- the first contact piece 8 has a plurality of grooves 8a formed at the distal end thereof to be in contact with the plurality of ropes 2 and a wide second fastener 2 extending at the base end in the direction in which the plurality of ropes 2 are arranged.
- a long hole 8b into which 4 is inserted is formed.
- a through portion 8 c communicating with the long hole 8 b is formed. With this through portion 8 c, the first contact piece 8 is attached to the bracket 6, The holding plate 22 and the second fastener 24 have been removed.
- the rope 2 is wound around the sheave 3 of the hoisting machine 1, and then the intrusion prevention tool 4 is attached to the mounting base 5.
- the first fastener ⁇ and the second fastener 24 are loosened and adjusted so that the groove 8 a at the tip of the first contact piece 8 comes into light contact with the mouthpiece 2. This adjustment is performed by changing the angle of the bracket 6 with respect to the mounting base 6 and moving the first contact piece 8 to the left and right in the SB row direction of the rope 2.
- the adjustment can be performed by rotating the intrusion prevention device 4 with the first fastener 7 as a rotation point with respect to the mounting base 6, so that the adjustment can be performed as compared with the conventional slide type.
- the installation space for the intrusion prevention device 4 can be small.
- the first contact piece 8 is made of urethane, which is an elastic body, it is possible to prevent the rope 2 that is in contact with the first contact piece 8 from being damaged.
- the intrusion prevention device 4 by installing the intrusion prevention device 4 first when installing the elevator device, falling objects such as small concrete pieces, screws, nuts, etc., from the upper part of the hoistway toward the sheave 3 at the time of installation. Even if it falls, the fallen object collides with the first contact piece 8 of the intrusion prevention device 4 and is prevented from entering between the sheave 3 and the rope 2.
- the second fastener 24 is loosened, and the first contact piece 8 is removed. In this removal, the first contact piece 8 is formed at the base end of the first contact piece 8 with the through-hole 8c communicating with the elongated hole 8b. Easy to remove from 2 and 2nd cotton attachment 24.
- the second contact piece 30 is firmly fixed between the bracket 6 and the holding plate 22 by tightening the second fastener 24.
- the second contact piece 30 is made of elastic urethane, even if the mouthpiece 2 comes into contact with the second contact piece 30, damage of the rope 2 due to the contact is prevented. can do.
- the angle of the intrusion prevention device 4 near the entrance on both sides of the sheave 3 with respect to the mounting base 5 is set to the first angle. This can be coped with by changing the fastener 7 as a pivot point.
- the intrusion prevention device 4 for preventing falling objects from entering between the sheave 3 and the rope 2 of the machine room-less hoist has been described. It is needless to say that the present invention can also be applied to other vehicles that wrap a rope in a hoistway such as a suspending vehicle of a counterweight.
- urethane which is an isotropic body
- rubber may be used in other examples.
- replacement of the contact pieces 8 and 30 can be easily performed by removing the second fastener 24 from the intrusion prevention tool 4.
- the mounting base 5 fixed to the hoisting machine 1 was used as the mounting member, and the intrusion prevention device 4 was attached to the mounting base 5, but in some cases, the intrusion preventing device was directly mounted on the hoisting machine. Good. Industrial applicability
- the present invention can be applied to an elevator apparatus that drives a rope wound around a sheave or the like to raise and lower a car and a counterweight.
