Description

[Detailed description of the invention] The present invention provides that even if a traveling device that reciprocates on a traveling rail installed in a dangerous place surrounded by a wall breaks down, the traveling device can be moved from the outside along the traveling rail. The present invention relates to a mobile device that can be moved.

2. Description of the Related Art A power manipulator system is a device that can perform work in a dangerous place by remote control. Overhead cranes are often used as moving devices for moving power manipulator systems within dangerous locations. Of course, the traveling device that moves the traveling girth of this overhead crane is also driven and controlled by an external operation.

By the way, if this traveling device malfunctions and the vehicle is able to travel but stops at an inappropriate location, this must be corrected. However, since it is impossible for people to enter for repairs, this running girder must be moved to a suitable location, that is, to a location with an entrance where the work equipment can be brought in by remote control. . As a countermeasure against warpage, it is possible to provide a backup drive means in the running gear, but since it is only used in emergencies, it would require too much maintenance and may not work in an emergency. I can't say it's an appropriate method.

Therefore, this invention solves these problems and
To provide a highly reliable and inexpensive moving device that requires almost no maintenance cost and operates reliably even in an emergency.

The structure of the present invention for achieving such an object includes a cable that is installed on the inside of the wall and spans along a traveling rail on which a traveling device moves back and forth, and a cable that is provided on the outside of the wall and that is connected to the cable. and a locking member that protrudes from the cable and is capable of locking onto the traveling device to move the traveling device. be.

The present invention will be described in detail below based on an embodiment shown in the drawings. In this embodiment, as shown in FIGS. 1 and 2, an overhead crane (traveling device) 3 moves back and forth on a traveling rail 2 laid inside a wall 1 along this wall 1. It's getting old. A chain 4 is spanned along the running rail 2 from one end to the other end by sprockets (rotary drive bodies) 5, 5a, 5b, and 5c. Chain 4 as shown in Figure 3
A drive shaft 6 passing through the wall 1 is connected to the sprocket 5 at one end, and a drive motor (drive means) is connected to the drive shaft 6 via a reducer 7 on the outside of the wall 1. 8 is provided. The drive shaft 6 passes through, in a sealed manner, a right side portion, that is, an inner portion, and a left side portion, that is, an outer portion in the figure, which are partitioned by the wall 1. Further, the drive shaft 6a of the drive motor 8 is provided with a handle (drive means) 9 that allows the sprocket 5 to be rotated manually.
This handle 9 is removed when the drive motor 8 is not malfunctioning. On the other hand, as shown in FIGS. 4 to 6, a locking protrusion 1 is provided on a portion of the chain 4 along the running rail 2, which can be locked to a protruding plate 10 protruding from the running section 3.
1 is attached.

By the way, if the drive device (not shown) in No. 3 that was able to run breaks down, it must be repaired, but the opening and closing door for carrying in the work equipment for that work is, for example, located on the ceiling at the left end in Figure 1. (not shown), the running member 3 may be moved to the left end of the running rail 2, which is directly below the loading opening/closing door.

Therefore, the locking protrusion 11 is pre-positioned at the right end position in FIG. If the chain breaks down and stops midway through 2, the drive motor 8 is driven to move the locking protrusion 11 of the chain 4 toward the left in FIG. As a result, this locking protrusion 11 locks on the protruding plate 10 of the running part 3 and moves this running part 3 to the left end of the running rail 2.

In this embodiment, since the locking protrusion 11 is provided on the engagement surface on the chain 4, this portion is attached to the sprocket 5.
~5c cannot be engaged and chain 4 is
It is impossible to rotate the locking protrusion 11 and lock it to the third protruding plate 10 running from the opposite side. However, if this locking protrusion 11 is made to protrude to the side of the chain 4 using the pin 4' of the chain 4, the above-mentioned problem will be solved, and the running part 3 can be moved to either side. It becomes possible.
Therefore, for example, even if the above-mentioned loading/unloading door is located directly above the center of the traveling rail 2, this can be sufficiently accommodated.

Further, in this embodiment, the chain 4 is used in the form of a cable, but this may be a wire or a rubber belt with teeth formed on the inside. In that case, the sprocket as the driving rotating body is replaced with a pulley or a gear.

Furthermore, according to the present idea, it is of course possible to manually operate from the outside of the wall 1 in an emergency by using only the handle 9 without providing the drive motor 8 as a drive means.

As explained above, according to the present invention, even if the traveling device in a dangerous place surrounded by walls breaks down, it can be easily accessed from the outside of the safe wall, which is completely isolated from the inside of the wall. The operation allows the traveling device to be reliably moved to a predetermined location. Furthermore, although the present invention is used only in emergencies and is often not used, its simple structure requires almost no maintenance costs during that time and can be maintained at low cost.

[Brief explanation of the drawing]

Figures 1 to 6 show an embodiment of the present invention in which the present invention is used as a device that can move the traveling rack of an overhead crane located inside a wall from outside the wall along a traveling rail only in an emergency. Figure 1 is a schematic view of the wall as seen from the inside, Figure 2 is its plan view, Figure 3 is a view taken along the line A-A in Figure 2, Figure 4 is an enlarged view of the main parts of Figure 2, 5 is a view taken in the direction of arrow A in FIG. 4, and FIG. 6 is an enlarged view of the main part of FIG. In the drawings, 1 is a wall, 2 is a traveling rail, 3 is a traveling device, 4 is a cable, 5, 5a, 5b, 5c are driving rotors, 8, 9 are driving means, 10 is a protruding plate, and 11 is a lock. It is a protrusion.
