【Example】

 The drawings show a preferred embodiment of the present invention.

The rail bodies 7 and 7 are laid on the base 6, and the moving bodies 1 and 2 on which the traveling wheels 8 are suspended are installed on the rail bodies 7 and 7 so as to face each other.

Stands 11 and 12 with bearings 10 and 10 attached thereto are erected on the base 9 of the moving body 1 and 2, and a spindle 13 is fitted into the bearings 10 and 10 so that the tip end projects rightward. A locking disk 15 having a locking body 14 for locking one end of the die steel material a is secured to the tip of the locking disk 15.

A sprocket (A) 16 is fixed to the main shaft 13 of the moving body 1 at a proper position, and a motor 17 with a speed reducer which is operated by a battery power source is provided on the base 9. The output shaft of the motor 17 with the speed reducer is provided. The sprocket (B) 18 is connected to the sprocket (C) 21 fixed to the input shaft of the reduction gear 20 via the chain (A) 19 and is connected to the output shaft of the reduction gear 20 (D). A chain (B) 23 is stretched between 22 and the sprocket (A) 16. The traveling wheels 8 are provided on the front, rear, left and right sides of the base 9, and the front wheel shaft 24 and the rear wheel shaft 25 are fitted and fixed to the traveling wheels 8 so that both ends of the front wheel shaft 24 and the rear wheel shaft 25 are attached to the base 9. Fit the bearing unit 26 fixed to the.

[0011] A traveling sprocket (A) 27 is fixed to the front wheel shaft 24 of the moving body 1 in place, and a sprocket (E) 29 is fixed to the output shaft on the base 9. Of the traveling speed reducer 31 is connected to the sprocket (E) 29 through the chain (C) 30 and the sprocket (F) 32 fixed to the input shaft of the speed reducer 31 for traveling. A chain (D) 34 is stretched between the sprocket (G) 33 fixed to the shaft and the traveling sprocket (A) 27.

A sprocket (H) 35 is fixed to the front wheel shaft 24, and a chain (E) 37 is stretched between the sprocket (H) 35 and the traveling sprocket (B) 36 fixed to the rear wheel shaft 25. To do.

In the figure, reference numeral 38 is a tension roller for adjusting the tension of the chain (E) 37, and 39 is a guide roller mechanism for guiding and moving the movable bodies 1 and 2 on the rail. Since this embodiment is configured as described above, the following operational effects are exhibited.

The flanges at the respective ends of the mold steel material a are mounted on the lock bodies 14 and 14 of the pair of moving bodies 1 and 2, and the mold steel material a and the lock body 14 are fixed to each other by an appropriate means. The vertical steel material a is laid horizontally between the moving bodies 1 and 2.

When the traveling electric motor 28 with a reduction gear attached to the moving body 1 is rotated, the sprocket (E) 29, the chain (C) 30, the sprocket (F) 32, the speed reducer 31 and the sprocket (G ) 33 ・ Chain (D) 34 ・ Power is transmitted to the traveling sprocket (A) 27 to rotate the front wheel shaft 24, and at the same time, the sprocket (H) 35, chain (E) 37, and traveling sprocket (B) 36 are used for the rear wheels. Since the shaft 25 rotates, the moving body 1 moves, and the moving body 2 is pushed by the shaped steel material a installed between the moving body 1 and the moving body 2, and the moving body 1, the shaped steel material a, and the moving body 2 are integrated. When moving on rails 7 and 7 to a predetermined place in the state of an object and stopping the rotation of the traveling electric motor 28 at that place and rotating the electric motor 17 with a reduction gear of the rotary drive mechanism 4, the sprocket ( B) 18, Chain (A) 19, Sprocket ( ) 21, a reduction gear 20, a sprocket (D) 22, a chain (B) 23, a sprocket (A) 16, and the main shaft 13 is rotated and fixed to the locking body 14 of the moving body 1. Is rotated together with the locking body 14 of the moving body 2 so that the worker can easily process it. The rotation is stopped at an appropriate position to perform welding work or painting work.

As described above, according to the present invention, since the shaped steel material a can be moved to a predetermined place and processed at that place, the worker can work the welding equipment and the coating equipment such as the welding equipment as in the conventional work. It eliminates the need to bring the machine to a certain place for work, significantly shortens the time required for processing to prepare the equipment for processing, and arranges the layout of the processing equipment in the factory tidily to improve the working environment significantly.

Further, since the painting place can be limited to a certain place, it is possible to prevent the floor surface of the factory from being contaminated by paint splashes or the like due to painting work.

Further, as shown in FIG. 5, it is possible to switch the rail body 7 at a point and introduce a pair of moving bodies 1 and 2 into the service line to move the rail body 7 to a specific processing site.

Further, depending on the size and weight of the processed member, the traveling drive mechanism 4 and the rotation drive mechanism 5 attached to the moving body 1 are also attached to the moving body 2 so that the traveling and rotating drive mechanisms of the moving bodies 1 and 2 are attached. It is also possible to activate 4, 5 simultaneously.

[Effect of the device]

 Since the present invention is configured as described above, it is possible to eliminate the need for lifting and transporting by a crane or reversing, which is required when processing a long-steel shaped steel material, etc., and rails laid on the base. It is very safe because the pair of moving bodies can transport or invert the shaped steel material and so on, and the rotation drive mechanism rotates the work piece at the position where the operator can easily process. As a result, it is a practical and excellent self-propelled steel moving device with a good working environment in which the working man-hours are reduced, the quality is improved, and work can be performed with peace of mind.
