Accordingly, even in case of a large-scale inclined dome, the outside maintenance work can be facilitated, and the economical scaffolding device can be constructed, securing the excellent safety.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inclined dome scaffolding device. More specifically, the present invention relates to a new scaffolding device capable of traveling, which can facilitate external maintenance of a large-diameter long-distance inclined dome.

[0002]

2. Description of the Related Art Conventionally, there has been known a dome structure in which an automatic traveling device such as an escalator is arranged in an internal space. In this dome structure, members such as glass and film body are arranged on a steel frame structure, and it is also used as a device for moving a person in the dome while enjoying the outdoor scenery. However, with respect to these dome structures, maintenance of the external areas such as glass and film body is very troublesome, and in particular, it is extremely difficult to perform maintenance on the inclined surface.

[0003] Generally, a worker has been arranged at a predetermined place and moved by a lift device or a crane device to deal with the problem. However, for a larger tilted dome, such work is performed. Has a problem that it requires a huge amount of labor and cost, and in addition, there is a situation in which it cannot be dealt with depending on a crane device or the like. Especially, the diameter is 1
In the case of a large-scale inclined dome with a length of 0 m or more, a length of 150 m or more, and an altitude difference of 70 m or more, maintenance with these ordinary devices was not practical and some new measures were required. .

The present invention has been made in view of the above circumstances, overcomes the limitation of the conventional device, and facilitates the external maintenance of a large-scale tilt dome, and further, the work safety. The goal is to realize a new policy that is excellent and economical.

[0005]

In order to solve the above problems, the present invention provides a scaffolding assembly, which is arranged outside a slanted dome and is composed of horizontal scaffolds, and a slanted dome body or a sash frame attached thereto. A rail support attached to the rail member to support the scaffold assembly so that the scaffold assembly can travel freely, and a wire rope device for vertically moving the scaffold assembly with a winch device arranged on the top of the inclined dome. An inclined dome scaffolding device is provided.

More specifically, in the present invention, a scaffolding assembly is provided around the outside of the inclined dome, and a wire rope device is connected to the top and both sides of the scaffolding assembly facing the inclined dome. The arrangement is such that the scaffold assembly is run by arranging and hoisting it at the same speed with a uniaxial three-body winch and releasing it. This scaffolding device facilitates external maintenance of the tilted dome and ensures work safety. The economy of maintenance is also good.

Examples will be shown below to describe the scaffolding device according to the present invention which can travel freely.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 of the accompanying drawings illustrates an outline of the appearance of an embodiment of the present invention. For example, as shown in FIG. 1, in the inclined dome scaffolding device of the present invention, the inclined dome (1) has a horizontal distance (L) of about 170 to 180 m and a height difference (H) of about 85, for example.
large scale with a slope distance (l) of about 200 to 220 m,
For long-distance inclined dome. In this case, as shown in FIG. 2, the diameter (D) is set to a large diameter of 10 to 15 m. Inside the sloping dome (1), an escalator, a sloping elevator, and even stairs are arranged.

In such an inclined dome (1), the scaffolding device of the present invention is arranged outside the inclined dome (1) such as the glass surface, as shown in FIG. A scaffolding assembly (2) composed of horizontal scaffolds can be vertically moved by a wire rope device (4) connected to a winch device (3) arranged on the top of the inclined dome (1).

In order to enable this vertical traveling, FIG.
As illustrated in FIG. 1, the scaffolding device of the present invention has the traveling support device (6) for the scaffolding assembly (2) for the rail member (5) attached to the main body of the inclined dome (1) or the sash frame attached thereto. Be prepared for. Inclined angle (α) of the inclined dome (1)
The rail member (5) is also tilted in accordance with the size of the above, and a proper number and a proper structure of the traveling support device (6) are provided so that the rail member (5) can be smoothly supported by traveling.

In FIG. 3 and in the example of FIG. 4 showing this as a front view, the scaffolding assembly (2) comprises a safety handrail (2).
1) and a circular handrail etc. for further safety are properly installed, and scaffolds having a length about half of the outer circumference of the inclined dome (1) are arranged on both sides of the inclined dome (1). , A traveling support device (6) is provided at the top, middle and bottom of each of them.

FIG. 5 illustrates the traveling support device (6) at the lower end. The rail member (5) is supported by running by rollers (7) on the left and right sides and on the upper side. Further, a spring (8) is used to absorb vibration and shaking. Further, FIG. 6 shows the traveling support device (6) at the top. Similarly, the scaffolding assembly (2) is supported by the left and right and upper rollers (7) for running support. And, it also has a locking portion (9) of the wire rope (4).

Of course, the traveling support device (6) is not limited to these structures. Needless to say, as the material thereof, for example, the roller (7), various materials such as a nylon roller as a hard resin for absorbing vibration can be adopted. As described above, the wire rope (4) is connected to the scaffolding assembly (2). In this case, the locking device is the size, shape, and travel support device (6) of the scaffolding assembly (2). It can be selected accordingly. A plurality of wire ropes (4) can be appropriately used in order to stably wind the wire rope (4) and vertically release the scaffolding assembly (2) by releasing the wire rope (4).

In the example shown in FIG. 1, three wire ropes (4) are used, for example, as shown in the arrangement example of FIG. It is connected to the body (2). Then, as shown in FIG. 7, a winch device (3) having a single axis and three bodies is used to move the three wire ropes (4) at the same speed. In this case, the power consumption is reduced by using a low speed winch of, for example, 0.75 kw and 3.4 m / min, and by using a wire rope (4) made of stainless steel,
It is also possible to prevent the tilted dome (1) from becoming dirty and extend its life. Of course, the winch device (3) can also be operated remotely.

Further, in detail, it goes without saying that the scaffolding device of the present invention can have various modes.

[0016]

As described above in detail, according to the present invention, a new scaffolding device which can easily perform external maintenance work, is excellent in safety, and is economical to run even in a large-scale inclined dome is provided. It
