。Conventionally, the method of inserting an inspection device or the like into a pipe to inspect the pipe from the inside is carried out using a pressure feeding type using fluid pressure or a self-propelled type internal pipe traveling device having a traveling function. These tow cables or guide lines for power, communication and control. For this reason, it is difficult to insert the cable or guide wire deep into the pipe entrance due to frictional resistance caused by contact with the inner wall of the pipe.

管の通過も可能としたものである。The present invention relates to an in-pipe running device for properly laying the guide wire. Normal piping is mostly straight pipes, but it also includes joints, bent pipes, and branch pipes. This causes the aforementioned frictional resistance problem. As a means of solving this problem caused by frictional resistance, the present invention eliminates the cable to be towed, and the guide wire is wound around a take-up reel beforehand and mounted on the traveling device, so that the guide wire is unwound equal to the amount of travel at the same time as the travel starts. It is a permanent solution that can be solved by doing this. In addition, problems caused by the shape of the piping can be solved by making the front and rear parts of the traveling device bullet-shaped, arranging multiple traveling wheels on the same circumference and in the axial direction, and further dividing the traveling device in the axial direction. By transmitting power between them via a universal joint, it is possible to pass through curved and base pipes.
本発明の実施例を図面を用いて説明する。第1図は、本
発明の一実施例を示したものである。胴体1の先頭部2
および後部3は砲弾型をしている。Embodiments of the present invention will be described using the drawings. FIG. 1 shows an embodiment of the present invention. Top part 2 of body 1
The rear part 3 is shaped like a cannonball.

を導通させるとモータ4とウオーム6を経由して複数個
のウオームホイール8は全て同じ向きに回転を始める。A motor 4 and a battery 5 are built inside the front part 2. A worm 6 is connected to the rotating shaft of the motor 4.
The other end of the worm 6 is rotatably held by a bearing 7. A plurality of worm wheels 8 are arranged on the worm 6 in three or more rows in the axial direction and at least three or more on the circumference, and the worm wheels 8 are sized so that a part thereof protrudes from the body 1. Now, motor 4 and battery 5
When electrically conductive, the plurality of worm wheels 8 all start rotating in the same direction via the motor 4 and the worm 6.
この時、ウオームホイール8の回転が正転となるよう電
池5をモータ4に接続しておく。At this time, the battery 5 is connected to the motor 4 so that the worm wheel 8 rotates in the normal direction.
この状態で、先頭部2から配管の入口に挿入すれば、管

量と等しい長さの線材10が繰り出されることになる。On the other hand, a wire rod 10 is wound inside the rear portion 3.
1 is built-in. This reel 11 is a wound wire 1
By pulling one end of the wire rod 10, the reel rotates and the wire rod 10
It is set up so that it can be played out one after another. Therefore, if one end of the wire rod 10 is fixed near the inlet of the pipe, as the traveling device moves, tension is applied to the wire rod 10 and the reel 11 rotates. The wire rod 10 will be paid out.

Whether the wire 10 is made of a flexible material or a rigid material, the wire material 10 may be made of a tensile material that can guide the test device, for example,
Use carbon fiber, etc.

より、胴体1の軸方向を柔軟構造とすることができる。FIG. 3 shows that the worm 6 shown in FIG. 1 is divided into rings along with the body for each worm wheel 8, and the divided worms 6 are connected to each other by a universal joint 14, and the divided bodies 1 are connected to each other. They are connected by bellows 13. Also, 7
The motor 4 and the body 1a are similarly divided and connected. The leading part 2 and the motor 4, and the rear part 3 and the rearmost body ln are connected only by the bellows 13 because there is no need to transmit rotational power. By adopting such a configuration, the body 1 can have a flexible structure in the axial direction.

Even if a branch pipe is interposed at the contact portion between the worm wheel 8 and the inner wall surface 9 of the pipe, the worm wheel 8 will not fall into the branch pipe because the worm wheels 8 are arranged in multiple rows on the shelf in the traveling direction. In addition, if it becomes impossible to run for some reason, it can be recovered from inside the pipe by pulling the wire.
