In addition, a plurality of revolving frames (6) are rotatably supported on a post unit (3a) of the post (3) via a flange portion (3b) and a bearing (7). On the inner periphery of the bracket through a bracket (8) at a position facing the revolving frame (6) A shaped rail (9) is laid, and an outer end of a crane main girder (10) whose inner end is connected to a revolving frame (6) is movably supported on the circular rail (9). A hoist rail (11) is provided along the lower surface of the main girder (10) so as to allow the hoist (12) to run freely, and a radio transmission for turning the crane main girder (10) and running the hoist (12) is provided. Machine (14) is provided.

[0009]

[0010]

In the multi-stage turning traveling crane using a cylindrical body constructed as described above, horizontal turning, horizontal traveling, and hanging operations are easy, and by changing the position of the crane main girder, simultaneous operations of multiple types of work can be performed. And safe and efficient construction.

Further, a crane member such as a post member is carried in from the opening, assembled and installed, and disassembled and carried out.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, openings 2 and 2, which are small enough to carry in and take out a disassembled crane member, are formed in the cylindrical body 1 in the course of sliding.

3 to 5, on the axis of the cylindrical body 1, a post 3 is fixedly erected by a plurality of anchors 3c. The post 3 is a multi-section post unit 3a.
Is added and erected according to the height of the cylinder 1, and on the top,
A cover 4 is provided, and a plurality of wires 5 are stretched between the cover 4 and the inner periphery of the cylindrical body 1.

The post 3 has multiple stages (2 in the illustrated example).
A (stage) turning frame 6 is provided. The revolving frame 6 is rotatably supported on the post unit 3a via a flange 3b and a bearing 7.

On the other hand, a circular rail 9 is provided on the inner circumference of the cylindrical body 1 at a position facing the revolving frame 6 via a bracket 8.
Is laid. The rail 9 has a crane main girder 1
0 of the crane main girder 1
0 is connected to the turning frame 6 at its inner end.

A hoist rail 11 is provided along the lower surface of the crane main girder 10, and the hoist rail 1
1, a hoist 12 is suspended so as to run freely. In addition, the code | symbol 13 in a figure is the driving | running insulating trolley for power reception, and 14 is a radio transmitter.

At the time of assembling, the rail 9 is attached via a bracket 8 to an anchor (not shown) inserted when the cylindrical body 1 slides.
Install.

Next, the first post unit 3a is erected on the axis of the cylindrical body 1 via an anchor 3c, and the second and third post units 3a are mounted in accordance with the height of the cylindrical body 1. Then, the cover 4 attached to the top is connected to the cylindrical body 1 with the wire 5 and the post 3 is fixed.

Therefore, in the illustrated example, the turning base 6 is attached to each of the post units 3a of the third and fourth sections, and the crane main beam 10 is attached to the turning base 6 and the circular rail 9.

Next, a hoist rail 11 is attached to the main girder 10, and the hoist 1 is attached to the hoist rail 11.
Install 2.

Finally, the traveling insulation trolley 13 and the radio transmitter 14 are installed, and the assembly is completed.

In operation, the radio transmitter 14 is operated, the crane main girder 10 is turned, the hoist 12 is run, and lifting is performed at an arbitrary place in the cylindrical body 1.

[0024] Demolition and removal work is performed in the reverse order to the above.
In both the assembling and dismantling work, the disassembled members are carried in and out through the opening 2.

[0025]

According to the present invention, since the crane is constructed as described above, the crane is divided into small parts and can be easily assembled and disassembled. Therefore, it is only necessary to provide the cylinder with an opening as small as possible. In addition, the work is horizontal movement for both turning and running, which is efficient and safe. It is also possible to increase or decrease the number of cranes according to the scale of the construction.
