The L-shaped, U-shaped and O-shaped traveling rails 4 can be assembled along the wall surface.

FIG. 6 shows another embodiment of the present invention. A pipe clamp 23 is integrally joined on the vertical portions 6A and 6B of the main body 2 shown in FIG. The left and right pipe rail travel devices 1 are respectively connected by pipes 3.

FIG. 7 shows an XY direction overhead crane 24 using the pipe rail traveling device 1 provided with the pipe clamp 23 shown in FIG. This is attached to a Y-direction traveling rail 26 laid parallel to the ceiling so as to straddle the pipe rail traveling device 1, and both ends of the X-direction traveling rail 27 formed of the pipe 3 are connected to the pipe clamp 23, and this X-direction traveling is connected. The rail 27 is attached so as to straddle the pipe rail traveling device 1 in which the L-shaped arm 18 shown in FIG. 4 is joined, and the chain block 20 is attached to the L-shaped arm 18.

In the XY direction overhead crane 24 assembled in this way, the chain block 20 moves in the X direction on the X direction traveling rail 27 by pulling the chain of the chain block 20 back and forth, and left and right. 26 can be moved in the Y direction. Thus, the XY direction overhead crane 24 can be easily assembled by combining the three pipe rail traveling devices 1 and the three pipes 3 to be the traveling rails 4.

FIG. 8 shows another embodiment of the present invention, which is a hoist crane 28 using the pipe rail traveling device 1. This is because the pipe rail traveling device 1 to which the L-shaped arm 18 shown in FIG. 4 is attached is installed in parallel with two traveling rails 4 on the ceiling, and the pipe rail traveling device 1 is directed to the L-shaped arm 18 respectively. The pipe 3 is connected to both ends of the L-shaped arm 18 by pipe clamps 23 on the opposite side. Further, a U-shaped bracket 30 is attached to the lower part of the pipe 3, and a winch 32 is attached to the inside thereof.

One end of a wire 34 is wound around the winch 32, the other end of the wire 34 is connected to a bracket 30, a pulley 35 is attached to a U-shaped curved portion of the wire 34, and a hook 36 is attached to a lower portion of the pulley 35. is there. Reference numeral 37 denotes a power cable.

The hoist crane 28 configured as described above suspends the load 38 on the hook 36 and drives the winch 32 to rotate the drum 33 and wind the wire 34. In this state, the load 38 is pulled along the traveling rail 4. Can be moved.

FIG. 9 shows another embodiment of the present invention, which is a transport device 40 using the pipe rail travel device 1. This is formed by combining a horizontal frame pipe 3 arranged in parallel with a pipe clamp 29 that crosses two horizontal frame pipes 3 arranged orthogonally and two vertical frame pipes 3 arranged in parallel, and the horizontal frame pipe 3 is combined. A carriage 41 is formed by joining to the pipe clamp 23 of the pipe rail traveling device 1 shown in FIG. 6, and two pipe rail traveling devices 1 are mounted on the traveling rail 4 laid on the floor or the ground in parallel. is there. This is to carry the load 38 by placing the load 38 on a carriage 41 formed by combining the pipe 3 with the well and pushing it on the traveling rail 4.

In this case, the traveling rail 4 can be made several tens of meters long by being connected by a pipe joint. Since the inexpensive pipe 3 can be used as the traveling rail 4 in this way, it is extremely cheap compared to a transporting device in which sleepers are laid on top of gravel as in the past and steel I-shaped rails are laid on this. Rails can be laid on the vehicle, and the conveying device 40 can be easily assembled by simply combining the traveling device 1 and the pipe 3, and can be disassembled in a short time. In addition, the structure which connected the wire 34 of the winch 32 to a pipe rail traveling apparatus, and was made to drive | work automatically may be sufficient.
