Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a device for suppressing wind noise generated by a cab that moves up and down in a hoistway.

[0002]

2. Description of the Related Art A conventional elevator installed in a hoistway is usually constructed as shown in FIG. In the figure, 1 is a hoistway, 2 is a car room surrounded by a thin steel plate, 2a is a car floor, 3 is a counterweight, and the car room 2 and the counterweight 3 are suspended by hoisting ropes 4, A balance rope 5 is suspended between the two. 6 is a car door, 7 is a landing door, and 8 is a front edge of a floor on which a sill (not shown) of the landing door 7 is installed, which projects into the hoistway 1. In recent years, the speed of elevators has tended to increase with the rise of buildings, and high-speed elevators of 240 m / min or more are not uncommon and are being installed one after another. When the cab 2 of such a high-speed elevator passes the counterweight 3 and when it passes through the front edge 8 of the floor,
A problem that can be neglected in a low-speed elevator becomes a problem when passing through a portion such as a device installed in the hoistway 1 that protrudes from the surface of the hoistway 1. That is, the cab room 2
When passing through another device, the air passage cross section between the cab 2 and the other device changes abruptly, causing air pressure fluctuations based on this. Even if there is no such change in the cross section of the air passage, since the shape of the cab 2 is square, the flow is separated at the corner a of the cab 2, and a large turbulence is induced at that part to cause pressure fluctuation. Accompanied by. This becomes a wind noise and is transmitted to the inside of the car room 2 to make passengers feel uncomfortable and anxious.

In order to solve these problems, a device equipped with an air conditioning device as shown in FIGS. 3 and 4 has recently been devised. That is, there is one in which a streamlined cover is attached to the upper part of the car room 2 and the lower part of the car floor 2a.

When the cab 2 rises, the air above it gradually flows laterally and rearward of the cab 2 along the surfaces of the side cover 11 and the rear cover 12. Therefore, the air flow 9 around the cab 2 is not suddenly disturbed and does not induce a swirl of high-speed air. Therefore, the pressure fluctuation of the air flow due to the vortex does not occur, and the generation of wind noise is suppressed. Further, by making the front cover 10 of the cab 2 vertical, the amount of air flowing in the front of the cab 2 is reduced, so that the discontinuous wind noise that appears every time the floor front edge 8 is passed is suppressed. It It is obvious that the same function as above is provided even when the car room 2 is lowered.

[0005]

In the case of an elevator without a conventional air-conditioning cover as shown in FIG. 2,
As shown in FIG. 2, by riding on the upper part of the cab, it was possible to perform maintenance and inspection of the equipment in the hoistway, including the counterweight. However, in the case of an elevator with a conventional air-conditioning cover as shown in Fig. 3, the maintenance room cannot stand on the cab because the upper part of the cab is streamlined. It was necessary to build a scaffolding for maintenance.

The present invention has been made to solve the above problems, and in an elevator having a streamlined airflow adjusting cover, it is not necessary to build a scaffold in the hoistway, and the streamlined airflow adjusting cover is provided. The purpose is to provide an elevator that has the same or better maintenance workability as an elevator without.

[0007]

The air conditioner according to the present invention has an inclined surface which is disposed on the outer edge of the cab and has the other end inclined from three directions toward a vertical line passing through the center of the cab. The inclined cover is provided with a scaffolding inspection door that opens at a fixed angle with the lower side as a fulcrum.

[0008]

[Operation] At the time of inspection, it can be used as a scaffold by opening the scaffolding inspection door at a certain angle with the lower side as a fulcrum.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. The same or corresponding parts as those in FIG. 2 are designated by the same reference numerals and the description thereof will be omitted. 10 is a vertical plane, 11 is an inclined cover inclined from the side of the car, and 12 is an inclined cover inclined from the rear edge of the car to the front. The inclined cover 12 is provided with a scaffolding / inspection door 13 that opens and closes with a lower fulcrum 13a as a fulcrum, stops opening at a substantially horizontal position, and has a strength enough to bear the weight of a maintenance worker. There is. When this door is not inspected, the door is closed to form the original inclined surface.

FIG. 5 is a view as seen from VV of FIG. 1 and shows a state in which the maintenance door is opened to the left and right. As can be seen from this figure, the scaffolding inspection door 14 is also attached to the side air conditioning cover 11 so as to open with the lower side as a fulcrum, and this door also has the strength to withstand the weight of the maintenance personnel. It is possible to inspect elevator equipment on the side of the elevator.

FIG. 6 is a view seen from the direction of line VI-VI in FIG.
Shown in. As described above, the rear and side air conditioning covers are provided with maintenance and inspection doors and scaffolds, but it is not always necessary to provide them at all places, and they may be attached only at necessary places.

[0012]

As described above, according to the present invention, an inclined cover provided from the three sides provided on the outer edge of the cab is provided, and at least one of the inclined covers is used as a scaffolding inspection that opens at a fixed angle with the lower side as a fulcrum. By providing the door, the maintenance staff can ride on it to perform the work. Therefore, the maintenance staff does not need to assemble a scaffold in the hoistway when performing maintenance and inspection in the hoistway. Further, since the work can be performed at a position closer to the wall surface of the hoistway, the work can be performed more easily and more efficiently than when performing the maintenance and inspection in the conventional elevator without the air conditioning cover.
