[Detailed description of the invention] [Technical field to which the invention belongs]

The present invention relates to a cable duct for accommodating a cable.

[Prior art and its problems]

Conventionally, a power supply device 5 as shown in FIG. 3 has been used to supply power to a bogie traveling reciprocally. That is, the power supply device 5 is provided with the duct 30 along the traveling path of the trolley (dust collector) 4, one end of the cable 32 is fixed at the center of the duct 30, and the other end is attached to the trolley 4. The cable 32 is configured to be accommodated in the duct 30 as the vehicle travels. Conventionally, shaped steel, lightweight shaped steel, and the like have been used as such a duct. However, there is a problem that the duct using these is heavy and it is difficult to obtain an optimal shape and size. Therefore, the present inventors have proposed a duct formed by sequentially connecting duct members having a length of about 4 m manufactured by extrusion of an aluminum alloy. In this duct, when connecting between adjacent duct members, the bottom of each duct member is individually fixed by a bracket, and each side wall portion is
An aluminum foil tape coated with an adhesive on one side is to be attached between the side walls of both duct members. However, when the duct is used, vibration occurs due to the movement of the bogie and the movement of the cable, and the movement of the cable causes the cable to slide on the side wall of the duct, so that the aluminum foil tape may peel off due to friction or the like. . If the aluminum foil tape is peeled off, there is a problem that various steps occur such as a step is generated between the side walls of each duct member, and the cable is caught by the step and causes abnormal wear. Conventionally, since only one cable accommodating portion is provided in the duct, if the traveling direction of the bogie changes, the cables vertically overlap in the cable accommodating portion, and the lower portion of the cable is pulled toward the upper portion. The cable could be unstable due to abnormal conditions. In view of the above-mentioned problem, the present invention can prevent the cable from being vertically overlapped, and can prevent a situation in which the lower portion of the cable is dragged toward the upper portion to cause an abnormal phenomenon, thereby stabilizing the cable. It is an object of the present invention to provide a cable duct that can be accommodated in a housing.

[Means for Solving the Problems]

SUMMARY OF THE INVENTION In order to solve the above-described problems, the present invention provides a cable duct in which a duct member having a predetermined length is sequentially connected along a traveling direction of the truck to accommodate a cable for supplying power to the truck. Wherein the duct member has a substantially U-shaped cross section by the side walls on both sides and a bottom part between the side walls, and is substantially perpendicular to the bottom at a center inside the bottom and has a height. A central wall portion formed lower than the side wall portion is provided so as to divide the width of the bottom portion into two, and the central wall portion separately accommodates the cables according to a traveling direction of the bogie. Are formed and formed.

[Action]

The width of the bottom portion is divided into two by the central wall portion formed at the inner central portion of the bottom portion, thereby forming the first storage portion and the second storage portion. In the cable duct, the cable is accommodated in either the first accommodating portion or the second accommodating portion according to the traveling direction of the bogie. That is, for example, when the cart moves in the right direction (the direction of the arrow M1) in FIG. 3 by the distribution member attached to the cart, the cable is guided so as to be accommodated in the first accommodating portion. Is the left direction of Fig. 1 (direction of arrow M2)
When moving, the cable is guided to be accommodated in the second accommodation section. In this way, each time the bogie reverses the running direction, the positions where the cables are accommodated in the duct are distributed so as to be different from each other, so that the cables do not overlap vertically, and the lower part of the cable becomes the upper part. A stable power supply by the cable is performed without being dragged and causing an abnormal phenomenon. The duct members are connected to each other by, for example, pins or aluminum foil tape.

[Embodiment of the invention]

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 3 is a front view of the dust collecting apparatus 1 using the duct 30 according to the present invention. The dust collecting apparatus 1 includes a rail 3 having a total length of about 90 m, a dust collector 4 reciprocating along the rail 3, and a power supply device 5 for supplying power to the dust collector 4. Consists of While traveling along the rail 3, the dust collector 4 cleans the spinning machine M with air blown out from a number of nozzles provided in the blow duct 11, and removes fly dust and other dust on the floor F from the tip of the suction duct 12. Inhale and clean. Meanwhile, the dust collector 4 receives the electric signal and the electric power from the power supply device 5 and drives the blower and the electric motor for traveling built in the dust collector 4. As shown in FIG. 3, the traveling section of the dust collector 4 is divided into three sections: section A, section B, and section C. The dust collector 4 can travel in all of these sections. If some running is not possible due to maintenance of the spinning machine M,
For example, the vehicle travels only in the A section or only in the B section. A cable guide 21 for fixing one end of a cable 32 is provided at the center of the rail 3, and a dust collector 4 is provided at the center of each of the both ends of the rail 3 and the cable guide 21 with an A section or a B section. Cable only when traveling 32
Intermediate reversing ducts 22, 22 are provided for stabilization. In addition, the rails 3 are provided with position sensors 23 and 24 for detecting the position of the dust collector 4 and a middle reversing unit 25 for switching the traveling direction of the dust collector 4 so as to travel only in the section A or the section B. , 26 are provided. FIG. 1 is a sectional front view of the duct 30 according to the present invention, and FIG. 2 is a side view of the duct 30 according to the present invention. The duct 30 includes a large number of duct members 31 connected to each other in a straight line. Each duct member 31 is made of an extruded material of an aluminum alloy, has side wall portions 31a, 31a, and a bottom portion 31b, and has a U-shaped cross section open at the top. In the center of the bottom 31b, the bottom 3
A central wall 31c that divides 1b into two is provided, and the width of each of the divided bottoms 31b is slightly larger than the width of the cable 32 accommodated therein. by this,
A first accommodating portion 35a and a second accommodating portion 35b for accommodating the cables 32 are formed. At the upper end edge of the side wall portion 31a of the duct member 31, an outwardly folded ear portion 51 is provided over the entire length, and the ear portion 51 forms a concave groove 52. Each of the duct members 31 has its bottom 31b supported by a supporting member 39 attached to the rail 3 at an appropriate pitch, and the concave grooves 52 of the duct members 31 adjacent to each other.
The pin 53 of the columnar shape is fitted over the
Are fixed by caulking with an appropriate tool at two places, for example. The diameter of the pin 53 is such that the pin 53 is not destroyed by the shear load applied to the pin 53 due to the vibration of the side wall 31a, and the side walls 31a connected by this have sufficient rigidity (for example, about 1.5 mm). It is. Thus, the adjacent duct members 31 are firmly connected to each other. Therefore, even when the dust collector 4 travels and the cable 32 moves, the side walls 31a of the respective duct members 31 do not vibrate separately.
There is no step between 31a, and the occurrence of various troubles such as the cable 32 being caught on the step and causing abnormal wear is prevented. Since the duct member 31 is made of an aluminum alloy, the lugs 51 are easily caulked, and the production of the duct member 31 is easy and inexpensive. Workability of the on-site installation work of the duct member 31 is good, and the work can be performed quickly, so that the construction cost can be reduced. The cable 32 is, for example, a flat cable having an appropriate number of cores (for example, 4 cores) having a flexible outer jacket made of synthetic rubber or the like. In this duct 30, the cable 32 is accommodated in either the first accommodating portion 35a or the second accommodating portion 35b according to the traveling direction of the dust collector 4. That is, when the dust collector 4 moves to the right (the direction of the arrow M1) in FIG. 3 by the distribution member 33 attached to the dust collector 4, the dust collector 4 is guided to be stored in the first storage portion 35a, and conversely. When the dust collector 4 moves to the left (the direction of the arrow M2) in FIG.
It is guided to be accommodated in. According to this, each time the dust collector 4 reverses the running direction, the positions where the cables 32 are accommodated in the duct 30 are distributed so as to be different from each other, so that the cables 32 do not overlap one another up and down. Stable power supply by the cable 32 is performed without causing the lower part to be dragged by the upper part and causing an abnormal phenomenon. According to the above-described embodiment, the bottom portion 31b of the duct member 31 is divided by the central wall portion 31c, and the first accommodating portion 35a and the second accommodating portion 35b are provided independently, so that they are accommodated in each. Cable 32 does not move to the other side.
Therefore, if the cable 32 is extremely long,
Even if the flexibility of the cable 30 is extremely large or the duct 30 is inclined, the cables 32 are stably housed in the respective housing portions and do not interfere with each other. In the above embodiment, the concave groove 52 is formed so as to open downward, but may be formed so as to open outward or upward. Although the central wall portion 31c is provided on the duct member 31,
This can be omitted. The shape, dimensions, structure, material, and the like of the duct member 31, the cable 32, the bracket 39, and the like can be various other than those described above.
