Field of the Invention The present invention, when shipping a shaped steel from a refinement yard of a shaped steel manufacturing plant, provides a wheel block required for stacking shaped steel on the shaped steel carrier, on the shaped steel carrier. Alternatively, it relates to a device installed on the shaped steel on the shaped steel carrier.

[0002]

2. Description of the Related Art At present, for example, when a shaped steel is shipped out of the factory from a refinement line of a large-sized factory (H-shaped steel, steel sheet pile, etc.),
After the shaped steels are combined and bundled by using a fine line piller, as shown in FIG. 9, such shaped steels A are mounted on the overhead traveling crane C equipped with a lifting magnet M.
Lifted by, shaped steel carrier B (or trailer)
Loading on top.

At this time, in order to stably stack the shaped steels A, a wheel block (lining) 1 is installed on the shaped steels A, the shaped steels A are piled on this, and this is repeated. Shaped steel A and wheel 1 are alternately stacked. In the present situation, such laying of stiles on the shaped steel carrier B is entirely dependent on manpower, and every time the shaped steels A are piled up, the worker rides on the worktable and puts the stilts manually. It is spinning.

[0004]

However, in the conventional method of manually placing and rotating a wheeled tree as described above, a person may enter under the suspended load of the crane, and the position of stacking the wheeled tree is 1 It may be over 6 m, which is dangerous work and heavy work. Therefore, in order to eliminate such a so-called 3K workplace, it is desired to mechanize the installation work of the tree.

In the field of loading plate-like members such as metal plates and steel plates, automation of insertion and installation of a wheeled wood which is inserted between plate-like members stacked in a number corresponding to the packing unit is performed. (For example, Japanese Patent Publication No. 53-46345, Japanese Patent Publication No. 53-
15575, JP-A-3-148411, Jpn.
7633).

However, the objects of these automated devices are products having a fixed rectangular parallelepiped shape in which plate-like bodies are stacked, and the product carry-in route is only one route, and the position of the product is always constant. Therefore, the installation position of the tree is always the same height and the same longitudinal position. For this reason, when the product shape and loading method are various and diverse, such as shaped steel, and there are multiple product loading routes, there are multiple installation locations and the wheelwood installation positions differ in the height direction and the longitudinal direction. Is not applicable.

The present invention has been made to solve the above-mentioned problems, and an object thereof is to automatically attach a wheel block to an arbitrary installation location for shaped steels having various product shapes and various loading methods. The purpose of the present invention is to provide a shaped steel wheel block installation device that can be installed in a desired manner.
