Description

[Detailed Description of the Invention] The present invention relates to a guide wire passing machine used when inserting and installing a new cable into an underground cable pipe.

Conventionally, when installing a new cable through an underground cable conduit, a guide wire is first passed through the cable conduit, then the conductor is passed through the cable conduit using this guide wire, and the cable is inserted into the cable conduit while being wound up with a winch. Conventionally, the guide wire used to pull out this kind of conductor is a long piece of split bamboo, or a hard vinyl pipe about 4 meters long. When using a guide wire made of bamboo, it is necessary to insert the split bamboo into the cable pipe, connect the conductor to the guide wire, and pull it out manually by two or more people.
In addition, when using a hard vinyl pipe, insert the vinyl pipe into the cable pipe while adding it, pass it through, connect the conductor to the guide wire, and pull it out. At this time, remove the connecting part of the vinyl pipe and The method of pulling out the wire was used, which required the labor of four people and about 20 minutes.
In both cases, the wiring work had drawbacks such as being inefficient and requiring a lot of manpower and time.

In order to eliminate the above-mentioned drawbacks, the present invention utilizes the flexibility and elasticity of synthetic resin to create a reel that can hold a long hard vinyl pipe rolled up. and a transfer wheel that can be freely rewound.

An example of the implementation of the present invention will be described below with reference to the drawings.A reel 1 has outer ring frames 2 and 3 having the same diameter, which are placed opposite each other at a predetermined interval, and a fixed interval is formed between these two outer ring frames 2 and 3. A plurality of U-shaped frame portions 4 are connected and installed in each frame, and these U-shaped frame portions 4 are connected to the outer ring frame portions 2 and 3.
A plurality of spokes 5 are fixed to the axle 6 at one end and fixed to only one outer ring frame 2 at the other end. By providing the spokes 5 only on the surface on the side of the frame portion 2, the other surface of the reel 1, that is, the surface on the side of the outer ring frame portion 3, is formed free from the spokes 5, and the U-shaped frame portion of the reel 1 is formed. A vinyl pipe 7 is formed on the inner periphery of the reel 1 formed by the reel 4 so that it can be wound and held freely due to its flexibility.
The upper and lower caterpillars 9, 10 are installed as a pair so that the raceway surfaces of these caterpillars 9, 10 can overlap each other, and each caterpillar 9, 10 is attached to a rubber track board 11.
A groove 12 for guiding the vinyl pipe 7 is formed in the center of the rubber track board 11, and the lower caterpillar 10 is fixed, and the upper caterpillar 9 can be moved up and down by a screw shaft 13. The reel 1 is rotatably mounted on the frame 14 by its axle 6, and the transfer wheel 8 is placed on the side of the surface of the reel 1 that is released from the spokes 5 and at the front of the reel 1. At the same time, this transfer wheel 8 is placed at a height position that sends the vinyl pipe 7 back to the reel 1 and is placed at a predetermined angle forward and downward on the frame 15.
and configure it.

Reference numeral 16 is a motor connected to the starting wheel of the caterpillar 10 at the bottom of the transfer wheel 8, and the caterpillar 9 at the top is formed only of a guide wheel.

Further, the inner diameter of the reel 1 surrounded by the U-shaped frame portion 4 is formed as a range within which the maximum deformation of the vinyl pipe 7 to be wound can be restored, that is, a range that does not exceed the plastic capacity.

Since the present invention has the above-described structure, the hard vinyl pipe 7 is wound and held on the inner peripheral surface surrounded by the U-shaped frame portion 4 of the reel 1 due to its flexibility and elasticity. Since one side of the reel 1 is released from the spokes 5, the vinyl pipe wound around the reel 1 can be pulled out and rewinded more freely than the side that is released from the spokes 5. Moreover, since the inner circumference of the reel 1 that can be bent by the U-shaped frame part is formed to have an inner diameter within the maximum deformation range in which the hard vinyl pipe can be restored, the vinyl pipe 7 pulled out from the reel 1 immediately restores its straight shape. Therefore, the vinyl pipe 7 pulled out from the reel 1 by the transfer wheel 8 is transferred to the sixth
As shown in the figure, the cable can be penetrated very easily by simply feeding it into the underground cable pipe 18 buried between the manholes 17 and 17'. In addition, since the transfer wheel 8 clamps the vinyl pipe 7 with two caterpillars 9 and 10 and is guided by grooves provided on the rubber track board 11, the vinyl pipe 7 may be damaged when it is pulled out and rewinded. It is possible to reliably hold it without any problems and pull it in the correct direction.

Furthermore, by equipping an automobile with the reel 1 and the transfer wheel 8 in advance, its mobility and workability can be significantly improved.

Therefore, the present invention provides a reel that can freely wind a hard vinyl pipe by utilizing the flexibility and elasticity of synthetic resin, thereby making it possible to use a hard vinyl pipe of the length necessary for running underground cable pipes. This eliminates the inconvenience of using pipes that have been cut into short lengths and connecting them, as was the case in the past, and it is also possible to mechanize underground cable installation work, which not only reduces the number of personnel but also increases work efficiency. ,
Furthermore, by equipping a car with the wire threading machine of the present application, mobility is improved, and furthermore, by providing a reel that can wind hard vinyl pipes, there is no need to cut long hard vinyl pipes. It has the advantage of simplifying storage, storage and management, and can be widely used in areas other than the line passing machine of the present invention.
