2. Description of the Related Art In a thermal power plant, it is necessary to regularly inspect and replace the heat insulating material on the inner wall of the furnace.
A large amount of waste is generated from each floor. Conventionally, this waste was transported to the ground by an elevator.

[0003]

When an object is conveyed from a high place as described above, the work efficiency can be improved by installing a dropping device (shooter). However, the conventional dropping device is intended for comparatively soft and lightweight items such as postal items and garbage, and on the other hand, there is a problem that a large amount of noise is generated at the time of dropping because the heat insulating material is a hard and heavy item. Further, when the dropping device is installed after the construction of the building is completed, the installation work is not necessarily easy because the existing device is installed and avoided.

The present invention has been made in view of such conventional problems.
The purpose of the present invention is to provide a waste dropping device that can reduce noise when dropping waste and facilitate installation work.

[0005]

The features of the present invention for solving the above-mentioned conventional problems and achieving the intended purpose are as follows.
In a waste dropping device provided with a waste input port and a guide pipe for guiding the input waste when it falls, the guide pipe is formed by joining a plurality of hollow double structure dividing members in the circumferential direction. To be formed. The split member is provided with concave joint portions or convex joint portions on both end faces in the circumferential direction, and is assembled in such a manner that the convex joint portions are fitted into the concave joint portions,
It is preferable that a plurality of band-shaped joining members are tightened from the outer peripheral side to join a plurality of members in the circumferential direction.

Further, it is preferable to provide a cylindrical shape retaining member for restraining the assembled divided member from the outer peripheral side and / or the inner peripheral side, and the shape retaining member is inserted with an end portion of the assembled divided member. It is more preferable to have an inner cylinder and an outer cylinder that form an annular groove.

[0007]

In the present invention, a plurality of hollow split member members are joined in the circumferential direction to form a guide tube.
The guide tube is formed in a double tubular shape and is lightweight.

Further, by assembling the plurality of divided members in such a manner that the convex joined portions are fitted into the concave joined portions between the adjacent divided members, the shift between the divided members is prevented, and further, the belt-like joined member is formed. A plurality of divided members are integrated into a tubular shape by tightening from the outer peripheral side via.

Further, by restraining the assembled dividing member from the outer peripheral side and / or the inner peripheral side via the tubular shape retaining member, the assembled dividing member is held in a tubular shape having a predetermined sectional shape. To be done.

Further, by inserting the end portion of the assembled dividing member into the annular groove between the inner cylinder and the outer cylinder of the shape retaining member, the assembled dividing member is held in a tubular shape having a predetermined sectional shape. To be done.

Therefore, even when the guide pipes 10, 10 ... Are connected vertically or diagonally in a complicated manner, for example, by installing them after avoiding the existing ones after the completion of the building, the installation can be suitably performed.

When the waste is dropped, the waste is dropped into the guide tube 10 through the charging port 70 of each floor. At this time, the waste may collide with the guide pipes 10 while falling, but the guide pipes 10 have a hollow double-structured dividing member 20,
Since the double cylinder 20 is formed, the noise at the time of collision can be reduced. Therefore, even a hard heavy object can be dropped appropriately.

The case where the split member 20 having the concave joint portion 27 at one end and the convex joint portion 28 at the other end is used has been described, but the split member having the concave joint portions at both ends and the split member at both ends are described. You may use it combining with the division member which has a convex junction part.

It should be noted that the dividing member 20 has an arc-shaped cross section.
Although the case where the cylindrical guide tube 10 is formed by using is described, the dividing member 120 having a linear cross-sectional shape shown in FIG. 10, the dividing member 220 having an arc-shaped cross-sectional shape having a small radius, and the like. It is possible to use dividing members having various cross-sectional shapes, and by combining these, guide tubes having various cross-sectional shapes such as the guide tubes 110 and 210 shown in FIGS. It can be formed in a retaining shape. The split members 120 and 220, the guide tube 1
The same parts of 10, 220, the dividing member 20, and the guide tube 10 are denoted by the same reference numerals, and the description thereof will be omitted.

[0024]

As described above, in the waste dropping apparatus according to the present invention, a plurality of hollow double structure dividing members are joined in the circumferential direction to form a guide tube, so that the guide tube can be suitably used. The noise can be reduced when the waste is dropped by forming it in the shape of a heavy pipe. In addition, the guide tube is made lighter to assemble / install,
It can be easily disassembled and removed.

Further, concave joint portions or convex joint portions are provided on both end faces in the circumferential direction of the split member, and the convex joint portions are fitted into the concave joint portions and tightened from the outer peripheral side via the belt-shaped joint members. This makes it possible to easily join the plurality of divided members in the circumferential direction.

Further, a cylindrical holding member for restraining the assembled divided member from the outer peripheral side and / or the inner peripheral side, for example, an inner cylinder forming an annular groove into which an end of the assembled divided member is inserted. By providing the shape-retaining member having the outer cylinder, the assembled divided member can be held in the tubular shape having the predetermined cross-sectional shape, and the guide tube having the predetermined cross-sectional shape can be preferably formed.
