Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a pipe tag attaching tool for attaching an identification pipe tag from the road to a pipe installed in an excavated trench.

[Prior art]

When a cable such as a telephone line is passed through a pipe body and laid in an excavated trench, horseshoe-shaped pipes made of vinyl chloride, for example, are installed at regular intervals on the outside of the pipe body so that the cable inside the pipe can be identified from the outside. Installing road signs.

By the way, multiple pipes through which cables are passed are laid in parallel, and mainly pipes with a length of 5.5 m are sequentially connected and buried in an excavated trench formed with a length of 20 to 30 m. However, as shown in Figure 4, color-coded semicircular identification pipe tags are attached to each pipe at approximately 1.5 m intervals. In particular, pipe tags are attached to pipes installed in parallel in a staggered manner to facilitate identification of adjacent pipes.

In conventional installation work, a worker enters an excavated trench and manually pushes the pipe tag directly onto the outside of the pipe body.

[Problem that the invention attempts to solve]

Installation work of pipe tags by direct acquisition is dangerous, as there is a risk of the pipe tags collapsing even if earth retaining is applied to the wall of the excavated trench. Attaching the tags by bending over them one by one required time and effort, resulting in poor work efficiency.

The purpose of the present invention is to eliminate the disadvantages of the conventional example,
A pipe tag that is attached to the outside of a pipe installed in an excavated trench can be easily pushed in from the street without the need for workers to enter the trench, improving worker safety and increasing work efficiency. The purpose of the present invention is to provide road tag mounting tools.

[Means for solving problems]

In order to achieve the above object, the pipe tag attaching device of the present invention fixes a curved pushing plate to the tip of the pushing rod, and pushes the pair of curved arm rods so as to cover the pushing plate from above. The gist is to attach it to a rod and bias the tip of the arm in the closing direction so that it can expand freely.

[Effect]

According to the present invention, a horseshoe-shaped identification pipe tag to be attached to the outside of the pipe body is attached to a push-in plate provided at the tip of a push-rod, and a pair of arm rods provided so as to be freely expandable so as to cover the push-in plate. The pipe label can be fitted to the outside of the pipe body by holding it with the pipe body, bringing the fixture holding the pipe label into contact with the upper surface of the pipe body, and pressing the push rod downward.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a front view showing an embodiment of the pipe tag attachment device of the present invention, in which a curved push plate 2 that matches the external shape of the pipe body is attached to the tip of a metal push rod 1 that is pushed into an excavated groove. A pair of curved arm rods 4, 4 are attached to the pusher rod 1 at the rear of the pusher plate 2 so as to cover it from above.

The arm rods 4, 4 are attached to the pusher rod 1 in such a way that their tips can be expanded freely, and in such a way that the tips are normally biased in the closing direction. Arm rod 4, 4 via pin 3
The proximal end of the push rod 1 is pivotally attached to the middle of the push rod 1, and tension springs 5, 5' are interposed between the arm rods 4, 4 and the tip of the push rod 1.

In addition, as another embodiment, the arm rods 4, 4 themselves may be elastic, and the ends of the arm rods 4, 4 may be fixed to the push rod 1, so that they can be pushed open using their elasticity. Conceivable.

On the other hand, as shown in FIG. 5, the pipe label 6 is made of elastic vinyl chloride, and is formed into a horseshoe shape with a predetermined width so as to surround more than half the circumference of the pipe body, and has a different color for each pipe body 7 to be fitted. is colored.

Next, how to use and operate the pipe tag 6 is to be attached to the pipe body 7 by pressing the back of the pipe tag 6 against the push plate 2 as shown in FIG. Both ends are held by a pair of arm rods 4, 4 so as to be pressed from both sides. At this time, since the arm rods 4, 4 are strongly pressed against the conduit tag 6 by the tensile force of the springs 5, 5, there is no fear that the conduit tag 6 will fall off downward. Next, by pressing the opening of the pipe label 6 against the upper surface of the pipe body 7 installed in the groove, and then pushing the push rod 1 from above in the direction of arrow a, the pipe The road tag 6 is pushed downward, and as shown in FIG. It slides and fits onto the outer periphery. Thereafter, when the push rod 1 is pulled upward, the arm rods 4, 4 are removed from the conduit tag 6, and the conduit tag 6 is tightened and fixed to the pipe body 7 by its elasticity.

In this way, a plurality of conduit tags 6 are attached to the pipe body 7 at regular intervals, and the conduit tags 6 are arranged and attached in a staggered manner to the plurality of pipe bodies 7 laid in parallel.

[Effect of idea]

As mentioned above, the conduit tag attachment tool of the present invention has a simple structure, and the worker can easily attach the conduit tag from the road without entering the trench, improving work safety. It is something to do. Moreover, since the installation work is a one-touch type that is simply pushed in from above, the work time and labor can be reduced, resulting in economical effects such as cost reduction.
