Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for mounting a cable protection tube of a predetermined length, which is vertically split by a slit, on the outer circumference of a cable such as an optical cable.

[0002]

2. Description of the Related Art Generally, in order to attach a cable protection tube to a cable such as an optical cable, a method of attaching the cable protection tube in advance before laying the cable and a method of attaching the cable protection tube to the laid cable afterwards There is a method of attaching a protective tube, and the former has a large overall friction resistance and requires a lot of human power to extend the cable.Therefore, the latter method of attaching a cable protective tube to the laid cable is generally used. Was adopted. When a cable protection tube is attached to the latter cable, the cable protection tube must have a longitudinally split cable protection tube. The cable is fitted into the cable protection tube while expanding the slit part of the cable protection tube, and the means for expanding the vertically split slit part in the cable protection tube is a field means,
For example, it is the current situation that a handle such as a screwdriver, spanner, or wrench is used for the slit portion.

[0003]

However, in the above-mentioned means, the slit portion is opened one by one with a handle such as a screwdriver, a spanner and a wrench, so that a lot of labor and time are required for the work. In addition, it is also a factor that causes a problem of damaging the cable itself.

Therefore, the present invention has been made in view of the above problems, and an object thereof is an extremely simple and easy operation without damaging the cable itself.
An object of the present invention is to provide a device for mounting a cable protection tube that can mount a cable protection tube on a cable such as an optical cable.

[0005]

In order to solve this problem, the following cable protection tube mounting device was created. That is, the invention according to claim 1 is a device for mounting a cable protection tube of a predetermined length vertically divided by a slit on the outer circumference of a cable such as an optical cable, and for supporting members on both sides. The main body portion of the apparatus includes a pair of arm members whose end portions are respectively fixed and separated so as to form a predetermined holding space, and restriction pieces formed on inner end edges of the pair of arm members facing each other. And at least one arm member of the pair of arm members is movably supported on the support member so as to open and close the holding space, and a cable such as an optical cable is supported by the pair of arm members. And the restriction piece of the arm member is cut into the slit of the cable protection tube, and the main body of the device is moved along the slit to attach the cable protection tube to the outer circumference of the cable. It is an gist.

With the above construction, the pair of arm members holds a cable such as an optical cable, and after the regulating piece of the arm members is inserted into the slit of the cable protection tube, the main body of the device is slit. It is possible to mount the cable protection tube on the outer circumference of the cable while moving along with and expanding the slit portion by the restriction piece.

According to a second aspect of the present invention, there is provided a cable protection tube mounting device according to the first aspect, wherein a connecting member for mounting a pulling line for moving the main body of the device is provided on the supporting member. Is the summary. According to the above configuration, the movement of the apparatus main body itself can be performed very easily.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to FIGS. As shown in FIG. 1, the apparatus for mounting the cable protection tube w of this embodiment has a cable k, such as an optical cable, whose ends are respectively fixed to flat plate-shaped support members 1a and 1b arranged on both sides. A pair of arm members 2a, 2b separated so as to form a predetermined holding space s to be held, and restriction pieces formed on inner end edges 3a, 3b of the pair of arm members 2a, 2b facing each other. Four
A device main body 5 is formed from a and 4b.

The pair of arm members 2a, 2b are formed in a substantially curved shape facing each other so as to secure the holding space s, and one arm member 2a has both ends at the support member. 1 a and 1 b are respectively supported by a single supporting part 6, 6 so as to be rotatable (opening and closing movements),
The other arm member 2b has one end fixed to the support member 1a by a plurality of bearings 6 and the other end detachably supported by the thumbscrew means 7 with respect to the support member 1b.

The restriction pieces 4a, 4b are formed in a substantially L shape, and are projected in a predetermined length over substantially the entire area of the inner end edges 3a, 3b facing each other of the pair of arm members 2a, 2b. It is configured such that it can be inserted into the slit ws of the cable protection tube w of a predetermined length that is vertically split by a single slit ws.

A shackle 10 composed of a U-shaped ring 8 for attaching a pulling line y for moving the main body 5 of the apparatus and a mounting bolt 9 is detachably attached to the ends of the both supporting members 1a, 1b. ing.

The apparatus for mounting the cable protection tube w of the present embodiment is constructed as described above, and the usage state thereof will be described.

Now, as shown in FIGS. 3 and 4, the other arm member 2b of the pair of arm members 2a and 2b is attached to the support member 1.
Part of the cable k such as an optical cable to which the cable protection tube w should be attached (outer periphery) is released by unconstraining the thumbscrew means 7 from b and opening the holding space s. Insert (hold) in s.

The other arm member 2b of the pair of arm members 2a and 2b is confined to the support member 1b by the thumbscrew means 7 in the opposite manner to the above, and the holding space s is closed.

Next, the restriction pieces 4a and 4b are inserted from the side of the support member 1a into the slit ws end of the cable protection tube w to be mounted, and then the tow line y attached to the shackle 10 of the support member 1a. Is used to pull and move the device main body 5 along the slit ws.

Along with the pulling movement of the apparatus main body 5, the slit ws of the cable protection tube w has its restriction pieces 4a, 4b.
The cable k is held by the pair of arm members 2a and 2b and is held in the cable protection tube w.

After that, the pair of arm members 2 which continued the above operation
The cable k in the embraced state is stored over the entire length in the cable protection tube w by a and 2b.

In the present embodiment, the fixed positions of the pair of arm members 2a, 2b with respect to the support members 1a, 1b may be variable so that the size of the holding space s can be changed.

The shape of the pair of arm members 2a, 2b is not limited to that shown in the figures, and may be a bent shape, for example.

[0020]

According to the invention of claim 1, while holding a cable such as an optical cable by a pair of arm members,
After inserting the restriction piece of the arm member into the slit of the cable protection tube, move the main body of the device along the slit to mount the cable protection tube on the outer circumference of the cable while expanding the slit portion by the restriction piece. You can

Therefore, the cable protection tube can be attached to a cable such as an optical cable by an extremely simple and easy operation without damaging the cable itself.

According to the second aspect of the present invention, the movement of the apparatus main body itself can be performed very easily.
