There is a replacement cable. For example, a local cable for collecting and providing information between terminal information devices such as road information boards, CCTVs, beacons, and various sensors and branch offices / offices, and information devices of terminals from local branches. Cables for pulling out to the road are arranged along the road. In addition, in the automatic driving road system, automatic operation control is performed while checking the situation with the distance sensor between the front and side vehicles, the guidance sensor on the road surface, etc.In the automatic toll collection system, the wireless charge between the passing vehicle and the check point In the road traffic information communication system, communication cables and the like are similarly arranged along the road to correspond to communication from a beacon installed to provide traffic congestion information and the like on the road surface. -ing

[0004] In order to remotely manage the operation and control of automobiles on the road in this way, advanced road management utilizing information equipment such as ITV, enhancement of information provision to users such as VICS, and ITS. In order to further promote the (Intelligent Transportation System), management optical fibers for communication and control shall be laid on general national roads and major prefectural roads, etc. in principle, and so-called information boxes will be used as accommodation space for that. A handhole called “Hall” will be provided for each appropriate section. That is, a protective tube having a diameter of, for example, about 300 mm is embedded and connected between the hand holes, and for example, 80 mm
An inner pipe called a sheath made of a high-density polyethylene pipe having a diameter of about mm is drawn in and, at the connection portion with the handhole, subjected to a waterproof treatment or the like to be water-tightly connected and fixed. An optical fiber is drawn into the inner pipe and passed through. At this time, since the sheath tube itself has a length of, for example, about 200 to 300 m corresponding to a distance between hand holes, for example, and is spirally wound and held on the drum body, The wire is drawn back into the protective tube in a rewinding manner.

[0005]

However, when the sheath tube is drawn through the protection tube, the protection tube itself is buried along the side of the road. This is performed by temporarily installing the device on a road side zone near the handhole side and forcibly towing it via a messenger wire or the like by a retractable winch device arranged on the other handhole side.

[0006] However, it is necessary to support the drum body in a freely rotatable manner in order to facilitate rewinding in such a draw-through operation, and to install a plurality of drum bodies to collectively pull in a plurality of sheaths. The diameter of the entire drum body holding and holding the sheath tube is 2500 to 3000 mm
In order to install the drum body on the side of the road or on the sidewalk because of its large size, it was necessary to implement a certain amount of traffic regulation on traffic.

[0007] In addition, the conventional drum body of this type is large and bulky, so that the installation area is large and the handling becomes troublesome. In addition, the drum body is removed after the pull-in operation is completed, and is transferred to another work site. In addition, it takes time, which makes the workability at the work site poor, and the time required for pull-in work makes it necessary to restrict traffic for a long time. It had to be even more dangerous.

Accordingly, the present invention has been made in view of the above-mentioned various existing circumstances, and for example, protects and stores an optical fiber or the like for the construction of a traffic control system as described above, and draws in a sheath tube. It is possible to reduce the weight of the drum itself that holds the tube in a rolled shape for drawing in the long tube, and it is easy to hold and set a new rolled long tube. It is possible to reduce the installation area and to improve the workability, and by doing so in a short time even on the road side zone, the impact on traffic traffic can be extremely reduced, and work can be done safely. It is an object of the present invention to provide a drum device for rewinding a long tube material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. Reference numeral 1 shown in the drawings is accommodated by being spirally wound, and is unwound from a predetermined pipe. This is a drum frame that holds a long pipe material P such as a high-density polyethylene pipe called a sheath pipe that is drawn into the road. The drum frame 1 holds and accommodates an installation base 10 formed in a frame structure so as to be installed and installed at a drawing-in work site, and a long tubular material P wound in a roll and rotated by itself to be elongated. It comprises a turntable mechanism 30 rotatably provided on the installation table 10 so as to unwind and supply the tube material P while unwinding (see FIG. 1).

The mounting base 10 is connected to a frame base 11 which is formed crosswise in a horizontal plane, for example, in a cross shape, and is substantially orthogonally connected to each end of the frame base 11 in a direction perpendicular to the frame base 11 itself. And a pipe-shaped joint portion 15 connected in a standing shape, which is detachably connected to and fixed to the joint portion 15, and which is positioned outside the long tube P on the turntable mechanism 30. And a support 27.

The frame base 11 itself is formed by, for example, welding and integrating a hollow square pipe in a cross shape.
A central support plate 12 formed, for example, in a substantially circular shape in a plane is fixed integrally on the upper surface at the center crossing portion by welding or the like, and the rotation center portion of the turntable mechanism 30 is mounted on the central support plate 12. Is to be supported.
The frame base 11 is provided with a turntable mechanism 3.

When the casters 33 provided on the lower surface are rolled, the frame-shaped rotation support guide 13 is integrally fixed by welding or the like when viewed from a plane that also supports the weight of the long pipe material P. The support guide 13 itself is formed of, for example, an L-shaped steel material.

The joints 15 are integrally fixed to the respective ends of the frame base 11 by welding or the like so as to protrude vertically with respect to the horizontal plane of the frame base 11 itself. Then, an adjuster member 21 and a connecting post 27 to be described later, which are inserted into the joint portion 15 itself by mounting screws 16 which are screwed from the outside so as to be able to advance and retreat from outside at respective protruding upper and lower portions, are connected to the joint portion 15. It is designed to be screwed and connected.

The adjuster member 21 adjusts the installation height and the like when the installation base 10 itself is installed and installed in a predetermined place such as a roadside zone, so that the entire horizontal level can be set and maintained. , And are detachably attached to the respective joint portions 15. As shown in FIGS. 2 and 3, the adjuster member 21 includes a bolt 22 which moves relatively up and down by, for example, screw rotation and an operation handle 2.
And a nut 23 provided with a four-sided nut 23. The slide part 2 supports and fixes the connecting column 27, which is inserted into the joint part 15 from below, onto the upper surface thereof.
The bolt 22 is mounted on the slide part 26 in a state where the bolt 22 is inserted into the slide part 26 itself, and the base part 25 abutting on the mounting position is fixed to the bottom surface of the bolt 22 inserted into the connection support column 27, A nut 23 that is slidably rotatable is screwed to the bolt 22 on the lower surface of the slide portion 26. By inserting and connecting the adjuster member 21 into the joint portion 15 from below through the connecting column 27, the nut 23 itself is rotated with respect to the slide portion 26 by the operating handle 24 of the nut 23, and the bolt 23 is rotated. 22 can be moved in the vertical direction,
The mounting table 10 can be set at a high position by protruding from the mounting table, and can be set at a low position by being immersed on the contrary. Reference numeral 22A in the figure is a stopper fixed to the upper portion of the bolt 22 so as to prevent the bolt 22 from being pulled out of the slide portion 26.

Further, as shown above, the connecting column 27 shown in FIG.
However, when the apparatus of the present invention is vertically connected in a multi-stage arrangement as shown in the figure, the adjuster is provided so that the lowermost one can be easily installed at the installation location. This is because the member 21 is configured.
The adjuster member 21 is of course the joint 1
It suffices if the height of the mounting table 10 itself can be adjusted by being inserted into the mounting member 5, so that the adjuster member 21 and the connecting column 27 may be configured separately.

The connecting column 27 itself is formed in a pipe shape and is connected to the joint portion 15 by, for example, being inserted into the joint portion 15. The height of the connecting column 27 is at least collected in a winding shape held by the turntable mechanism 30. It is not lower than the height of the long pipe material P. In addition, on the upper portion of the connecting post 27, a load-resistant pin is protrudingly inserted into the connecting post 27 so as to support the lower surface of the joint portion 15 of the upper mounting table 10 in the case of multiple stages in the vertical direction. The support member 28 is detachably mounted. Reference numeral 29 in the figure denotes a turntable mechanism 30.
This is a corrugated uneven protection pipe that prevents the long tube P from being damaged by the contact of the long tube P with the connecting column 27 located on the outer side of the long tube P.

On the other hand, the turntable mechanism 30 comprises a plurality of radially arranged support arm members 32 which are integrally fixed by welding or the like to a central rotating plate 31 which is rotated on the installation table 10, A caster 33 which is mounted on the lower surface of the end of the member 32 and rolls on the rotation support guide 13 of the mounting table 10 and a long tube P mounted on the support arm 32 is held from the inside. And a tube holding post member 34 which is detachably attached to a standing leg.

The center rotating plate 31 is provided with a turntable mechanism 30.
For example, a rounded flat surface is formed in a substantially hexagonal shape at the center portion of the lower surface of the central rotating plate 31, and is fixedly disposed on the central support plate 12 of the installation table 10 on the lower surface of the lower central rotating plate 31. The bearing means 14 is rotatably supported.

The support arm member 32 itself is formed of, for example, a hollow square pipe member, and is fixed between the upper and lower central rotary plates 31 in a six-element configuration arranged radially at equal intervals. The table frame is formed together with the central rotating plate 31 so as to place and hold the long tubular material P collected in a circular shape.

Further, the tube material holding post member 34 is supported on the support arm member 32 via a positioning post 35 which is slidably mounted on the support arm member 32, for example, so as to be fixed at an arbitrary position.
2 is detachably attached to a standing leg. Therefore, the positioning post 35 is, for example, a hollow slide body 36 slidably fitted to the support arm member 32.
For example, a mounting screw 37 which is screwed from the upper side so as to be able to advance and retreat from above and whose tip is pressed against the support arm member 32, and a mounting support column 38 which is substantially upright with respect to the support arm member 32 are provided. is there. Since the positioning post 35 holds the long tube P placed on the support arm member 32 from the inside thereof, the mounting support column 38 is located on the outer end side of the support arm member 32. It is provided with an outer diameter not larger than the inner diameter of the tube holding post 34 so as to be fitted inside the hollow tube holding post 34 itself. As shown in the figure, the tube holding post member 34 itself is a horizontal portion positioned above the long tube member P so as to securely hold the long tube member P mounted on the support arm member 32 without falling off. A fixing screw 39 is attached to a vertical portion of the vertical portion thereof, and is screwed so as to be able to move forward and backward so that the tip is pressed against the mounting support column 38.

The positioning post 35 may be a positioning post 35 having a structure that can be fitted into the groove corresponding to the support arm material 32 having a groove shape in cross section, or a mounting support column 38 formed in a hollow shape. It is also possible that the tube material holding post 34 is fitted in and screwed.

Next, an example of use in the embodiment configured as described above will be described. As shown in FIG. 5, for example, inside a protection pipe S connected by pipes between hand holes H constructed as a traffic control system, for example. In the case where a long tube material P such as a sheath is drawn in and drawn in so as to protect and store the optical fiber, the optical fiber is placed in the vicinity of one handhole H in, for example, a multi-stage shape or a multi-row shape. The invented device is arranged, and the long tube material P is connected to the messenger wire M from the other hand hole H side to convert the long tubular material P into the winch device W.
And so on.

In order to hold the elongate tube material P wound in a roll on the turntable mechanism 30 in such a drawing operation, the tube material holding post material 34 of the turntable mechanism 30 is removed and the upper part is opened. And keep it. Then, the long tube P is placed and set on the support arm 32 such that the inside of the wound long tube P is positioned outside the positioning post 35. Next, the tube holding post 34 is attached to the positioning post 35 located inside the rolled long tube P, and a horizontal portion of the tube holding post 34 is required above the long tube P if necessary. 32
Is set at an appropriate angle with respect to.
If necessary, the connecting column 27 is connected to the joint portion 15 to surround the long tube P and protect the long tube P, and in some cases, the tube holding post 34 and the connecting column 2
7 may be connected.

At this time, for example, in the case of using in a multi-tiered manner such as two-tiered upper and lower sections, the adjuster member 21 is attached to the joint portion 15 of the mounting base 10 although it is located at the lower level, while 1
The joints 15 are connected and supported by fitting the connecting columns 27 between the joint portions 15. In this way, they are stacked in multiple stages, arranged in a plurality of rows, and pulled out from each, a large number of long pipe materials P are collectively drawn into the protective tube S. The symbol G in the figure is a hand hole H
It is a guide member for guiding the long pipe material P when drawn into the inside.

After the use of the long pipe material P, the tube material holding post member 34 is removed and the long pipe material P is set again. When the drawing operation at the work site is completed, the long tube material P is stored as it is or disassembled. Or transport it to the next work site.

[0027]

Since the present invention is configured as described above, for example, a sheath is wound in a wound shape so as to protect and store optical fibers in the construction of a traffic control system so that the optical fibers can be drawn in. The long tube material P such as a tube can be held and set by rewinding, and the long tube material P itself can be held in a horizontal state, so that an operator can be attached to each drum frame 1 for monitoring or the like. It is possible to work safely and reliably without having to work. In addition, the overall height at the time of installation can be reduced, not only does not fall down due to wind etc., but also there is no feeling of oppression and the visibility is good, so traffic such as cars running on the road can be easily made The work safety can be ensured.
In addition, the apparatus of the present invention itself can reduce the weight of the drum frame 1 because its constituent members are frame-shaped, and can easily set and set a new rolled long tubular material P, and have excellent handleability. It is possible to reduce the installation area by making it possible to achieve a simple arrangement form, and it is excellent in workability, and it can be done in a short time even on the side of the road, so that the influence on traffic traffic can be extremely reduced and work can be done safely Is what you can do.

That is, in the present invention, this is a turn for placing the long tubular material P wound up in a horizontal state on the installation table 10 which can be installed at the installation location and can be stacked in multiple stages. This is because the table mechanism 30 is provided so as to be rotatably supported, thereby facilitating the work at the retraction work site, reducing the weight and size of the component members, and further reducing the influence on traffic, etc. Can be achieved.

The mounting table 10 is provided with an adjuster member 21 that abuts on a joint portion 15 which is connected to the end of the radially formed frame base 11 in an upright state at the installation surface.
Are removably connected and fixed, so that even if there are irregularities or other undulations at the retraction work site in, for example, a roadside zone, the height of each can be finely adjusted in response to these. Therefore, the horizontal level of the turntable mechanism 30 provided on the installation table 10 can be reliably and easily set, and the drawn-out rolled long tubular material P placed horizontally on the turntable mechanism 30 is drawn. With this, the turntable mechanism 30 itself is forcibly rotated, and the long pipe material P can be smoothly fed out.

Further, a standing leg-like connecting column 27 located on the outside of the long tubular material P mounted on the turntable mechanism 30 is removably connected to the joint portion 15, so that the mounting table 10 Can be stacked in multiple stages in the vertical direction, reducing the installation area of a large number of long tubing materials P which are arranged when a plurality of long tubing materials P are collectively pulled in, and thus, for example, for traffic traffic during work on a road. The influence can be reduced. In addition, it is possible to secure a space for storing the long pipes P in the turntable mechanism 30 when stacking in multiple stages, for example, by arranging and installing the multi-stage, multiple rows in multiple rows to collect a large number of long pipes P. Each turntable mechanism 30 when drop-in traffic
Can be independently and independently rotated, a large number of long pipe materials P can be pulled out at a time, and the pulling load by the winch device W can be reduced.

Further, since the connecting column 27 is disposed outside the long tubular member P to be placed and held, the long tubular member P to be placed on the turntable mechanism 30 is transferred to the tube holding post member 34.
In addition, it can be held from inside and outside, so that the long tube P can be prevented from dropping off, for example, during transportation to the installation location or installation at the installation location, and can be protected from the outside to prevent damage to the long tube P. is there.

The turntable mechanism 30 is mounted on the mounting table 1.
A plurality of support arm members 32 radially arranged on a central rotating plate 31 rotated on a zero, and a tube holding post member 34 is slidably and detachably provided so as to hold the long tube material P from the inside thereof. Therefore, mounting the long tube material P on the turntable mechanism 30 and then attaching the tube material holding post member 34 does not hinder the placement and setting work, and the length of the long tube material P is different. Even in the case where the diameters of the windings are different, it is possible to achieve a reliable holding correspondingly adjusted. In addition, the tube holding post member 34 does not not only hinder the drawing operation when sequentially pulling out the wound long tube material P from the outside thereof, but also when it is unnecessary together with the detachable connecting column 27. By removing it, the whole can be compacted and its storage and transportation can be facilitated.
