Embodiments of the present invention will be described below.

FIG. 1 is a front view showing an embodiment of a traveling crane of the present invention, FIG. 2 is a side view of a main part of FIG. 1, and FIG. 3 is a side view of a lower rail and a rail mount shown in FIG.

In these drawings, 1 is a traveling crane main body, 2 is a traveling passage of the traveling crane main body 1, 3 is an opening / closing portion for opening and closing the traveling passage 2, and 4 is provided on both sides thereof through the opening / closing portion 3. The lower rail 5 is one side 21 of the opening / closing section 3.
The traveling crane body 1 is supported by the lower rail 4 via wheels 6 and is guided by the upper rail 5 via upper guide rollers 7. The other side 22 of the opening / closing part 3 is used as a maintenance area 8 so that the end 41 of the lower rail 4 can be removed so that the removed space can be used as a forklift passage or the like.

Explaining each part in the above-mentioned embodiment, the traveling crane main body 1 is supported by the lower rail 4 via wheels 6, and the upper rail 5 via the upper guide rollers 7 by the lower rail 4. Lower guide roller 6
1, a traveling body 11 that is guided through the traveling body 11, an elevating platform 13 that elevates and lowers along a mast 12 of the traveling body 11, a push-pull type loading / unloading device (partly not shown) 14 mounted on the elevating platform 13. It is composed of. Reference numeral 15 is a traveling drive device, 16 is a lifting drive device, and 17 is a control panel.

The traveling passage 2 is linearly formed so as to connect the temperature-controlled room 91 and the room temperature room 92.
A load storage shelf (not shown) is provided along the traveling passage 2 in the inside of the storage unit 1.

Further, the opening / closing section 3 includes a temperature-controlled room 91 and a room temperature room 9.
It is provided on a partition wall 93 between the two and the traveling passage 2 can be opened and closed by a double door (not shown).

Further, the lower rails 4 are disposed on both sides (the temperature-controlled room 91 side and the room temperature room 92 side) of the opening / closing section 3 on the other side 22 (the room temperature room 92 side) of the opening / closing section 3. The end 41 of the lower rail 4 can be removed together with the rail mount 42, and the removed space can be used as a forklift passage or the like. In addition, the lower rail 4 from which the end portion 41 is removed is one side 2 of the opening / closing portion 3.
It is arranged only in 1 (constant temperature room 91 side).

The upper rail 5 is provided only on the one side 21 (the temperature-controlled room 91 side) of the opening / closing section 3.

The wheels 6 are attached to the lower frame 18 of the traveling body 11, and the traveling crane main body 1 is supported by the lower rails 4 via the wheels 6.

Further, the upper guide roller 7 is provided on the traveling body 11
The traveling crane main body 1 is guided to the upper rail 5 via the upper guide roller 7 and to the lower rail 4 via the lower guide roller 61.

The maintenance area 8 is provided on the other side 22 of the opening / closing section 3.
It is set to the room temperature room 92 side, and when the traveling crane main body 1 is maintained, the end portion 41 of the lower rail 4 is attached together with the rail mount 42, and the traveling crane main body 1 is pulled out to the maintenance area 8 for work. It is done like this.

Thus, the traveling crane of the present invention has the lower rail 4 when performing normal work (not performing maintenance work).
End 41 of the door is removed and the double door is open (not shown)
By closing the opening / closing part 3 with, the air-tightness of the temperature-controlled room 91 can be maintained. Further, when performing maintenance work, the end portion 41 of the lower rail 4 is attached together with the rail mount 42 so that the traveling crane main body 1 is pulled out to the end portion 41 of the lower rail 4. At this time, the control panel 17 side Although the upper guide roller 7 of FIG. 3 comes off from the upper rail 5, the upper guide roller 7 of the lifting drive device 16 side is configured to hold the upper rail 5, so that the upper rail 5 is connected to one of the opening / closing sections 3. Although the traveling crane body 1 can stand on its own even though it is arranged only on the side 21 (the temperature-controlled room 91 side), when the maintenance work is not performed even if the opening / closing section 3 having no special structure is used. The air-tightness of the temperature-controlled room 91 can be easily maintained. In addition, the end 4 of the lower rail 4
Since 1 can be removed, the space where the end portion 41 of the lower rail 4 is arranged can be effectively used as a forklift passage or the like when maintenance work is not performed.

The embodiments of the present invention have been described above, but the present invention is not limited to these. For example, the lower rail 4 remaining after the end 41 is removed is the opening / closing part 3
May be provided on both sides (the temperature-controlled room 91 side and the room temperature room 92 side).

Further, the space in which the end portion 41 of the lower rail 4 is disposed during maintenance work may be used as a load storage space during normal work (when maintenance work is not performed).

[0023]

Since the traveling crane of the present invention is constructed as described above, it is possible to use an opening / closing part having no special structure and to effectively use the space in which the lower rail is arranged as a forklift passage or the like. Can be used.
