Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe with a cable discharging function which is installed in an inner space of a pipe for accommodating cables such as communication and power cables.

[0002]

2. Description of the Related Art FIG. 4 (a) is a cross-sectional view showing a case where one of communication and power cables and the like is housed in a pipe according to the prior art, and FIG. It is sectional drawing at the time of accommodating several cables, such as a power cable, in a pipe.

That is, since the conventional pipe 3 for housing communication and power cables has a single hollow portion inside,
Even when one cable 2 or a plurality of cables 1 and 2 are accommodated in one tube 3, the accommodation space of the accommodated cable 1 and the installation space of the installed cable 2 are the same space, The single hollow portion was used.

[0004]

However, a tube having a single hollow portion in which the space for installing cables and the like is the same as the space in which the cables are laid is difficult to accommodate a plurality of cables and the like in one tube. If there is enough space, the cable can be laid without any problem. However, if there is not enough room in the accommodating space as the second and third cables are accommodated, bending or twisting of the cable will have an adverse effect, and the cable etc. And the number of tubes that can be accommodated is reduced, making it impossible to effectively use the space in the tube. In addition, when a new cable is laid in a pipe in which a cable already laid is present, the cable or the like comes into direct contact with the pipe, causing a problem such as damage to the cable or the like.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is possible to effectively and efficiently use a space in a pipe, and to easily and reliably lay a plurality of cables and the like without damaging the exterior of the cables and the like. It is an object of the present invention to provide a pipe with a cable discharge function that can perform the operation.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, a pipe with a cable discharging function according to the present invention is a pipe for accommodating a cable such as a communication and power cable, the pipe having a shape capable of being drawn into the inner space of the pipe. It is characterized by having a linear opening in the longitudinal direction of the pipe for discharging a cable such as a communication and power cable laid on the pipe.

Further, according to the present invention, in the above-mentioned pipe with a cable discharging function, a cable such as a communication and power cable laid on the pipe is discharged from the linear opening of the pipe. Is provided in a direction perpendicular to the longitudinal direction of the pipe, and the roller is provided so that the roller can be freely moved in the longitudinal direction of the linear opening.

The present invention also provides a pipe having a cable discharging function, wherein the pipe is drawn into a pipe for accommodating a cable such as a communication and power cable, and a sled member or a fall prevention member for facilitating the drawing of the pipe. Is provided on the pipe.

According to the present invention, when a cable or the like is laid, the cable or the like is laid on a pipe with a cable discharge function, so that the already accommodated cable does not cause any trouble. In addition, the cable can be easily and reliably laid, and the cables and the like can be reliably discharged from the pipe with the cable discharging function to the housing space, so that the space in the pipe can be effectively used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1A is a cross-sectional view of a pipe with a cable discharge function according to an embodiment of the present invention installed in an inner space of a pipe for accommodating a communication and power cable and the like, and FIG. It is sectional drawing which installed the pipe with the cable discharge function which concerns on another embodiment in the internal space of the pipe | tube which accommodates a communication and electric power cable, etc. FIG.
1 is a perspective view of a pipe with a cable discharging function according to an embodiment of the present invention, which is installed in an inner space of a pipe for accommodating a communication and power cable and the like. In the figure, 11 is a pipe with a cable discharge function, 12 is a cable discharge device, 13 is a sled member, 14 is a stored cable, 15 is a cable to be laid, 16 is a pipe for storing communication and power cables, 17 Is a laying space, 18 is a housing space, 19 is a stand, 20 is a linear opening, and 21 is a string for towing. In FIG. 2, the sled member 13 or the stand 19 is omitted.

That is, a pipe 11 having a cable discharging function is drawn into the inner space of a pipe 16 for accommodating a cable such as a communication and power cable, and is laid and fixed.
The pipe 11 with a cable discharging function is a pipe having a shape that can be drawn into the inner space of the pipe 16, and a longitudinal direction (axial direction) of the pipe for discharging a cable such as a communication and power cable laid on the pipe. Has a linear opening 20. In order to discharge a cable such as a communication and power cable laid in the pipe from the linear opening 20 to the linear opening 20, the rollers of the cable discharging device 12 are moved in the longitudinal direction of the pipe. A cable discharge device 12 was provided, which was mounted in a right angle direction and in which the roller was freely movable in the longitudinal direction of the linear opening. In order to install the pipe 11 in the pipe 16 for accommodating a cable such as a communication and power cable, the sled member 13 for facilitating the pull-in of the pipe 11 and the stand 19 for preventing the fall of the pipe 11 Is provided.

When a cable is to be accommodated in the pipe 16, a cable 15 is laid from one end of the pipe 11 with a cable discharging function to the other end, and the cable 15 is taken out from the linear opening 20 at one end of the pipe 11. Then, the cable discharging device 12 is installed in the opening 20. Thereafter, when the towing string 21 attached to the cable discharging device 12 is pulled from the other end of the pipe 11, the cable 15 is squeezed by the rollers attached to the cable discharging device 12 and the laying space in the pipe 11 is laid. From 17, it passes through the linear opening 20 and is sequentially discharged into the housing space 18 outside the pipe 11.

The cable discharge device 12 can be pulled from either end of the pipe 11.
FIG. 2 shows an example of pulling from right to left. FIG. 3 is a configuration diagram showing an example of the cable discharging device 12 according to the present invention. That is, when the cable discharge device 12 is pulled, the sliders 23 and 24 at both ends thereof are linearly opened.
Move in the longitudinal direction without disengaging with both side edges of the.

Further, a guide 25 for guiding the cable 15 discharged from the laying space 17 to the storage space 18 to the left or right is attached to the cable discharge device 12 by being squeezed by the rollers 22 mounted on the cable discharge device 12. By doing so, the cable 15 can be accommodated in a desired direction on the left or right side of the accommodation space 18.

When the cable is laid using such a pipe with a cable discharging function, the laying space 17 is always empty, and the cable 1 accommodated in the pipe 16 is always available when necessary.
The cable 15 can be laid without being hindered by the cable 4, and the housing space 18 can effectively house the cable 14.

[0016]

As described above, according to the present invention, when a cable such as a communication and power cable is laid, the cable is laid on a pipe having a cable discharging function, so that the cable already housed in the pipe may cause trouble. No matter how many cables, etc., can be laid easily and reliably, and cables can be discharged and stored from the pipe with cable discharge function in the desired direction on the left or right side of the storage space. Therefore, effective use of the space in the pipe is achieved.
