Abstract

PROBLEM TO BE SOLVED: To provide a tip head (camera head, etc.), for a connecting rod which has an excellent passing performance, can be matched with various types of space shapes in a duct which are produced in accordance with the size of the duct and the size of a cable in the duct without the necessity of the replacement of components, and provides the excellent workability. SOLUTION: A camera head 10 is composed of a head main part 1 attached directly to the tip of a connecting rod 3 and adaptors 2 which have wing-shapes and are attached to the left and right sides of the head main part 1 so as to be turned up and down. A connecting rod 3 is pushed into a duct to make the camera head pass through the duct. As the left and right wing-shape adaptors 2 can be turned up and down, when the camera head 10 is moved forward in the duct in which a power cable is already laid, the adaptors 2 are displaced in accordance with an effective space in the duct, so that a smooth connecting performance can be secured.

The above-mentioned conventional camera heads have the following problems. FIG.
The cylindrical camera head 10′1 of (a) falls down along the twist of the power cable 6 or gets caught on the joint of the pipeline 7. Although the spherical camera head 10'2 shown in FIG.
In the pipeline 7 laid, there is a problem similar to that of the cylindrical type, and since the diameter of the head is large, the range of the pipeline 7 that can be used is narrowed, and it is difficult to use the pipeline 7 in a small pipeline.
The whisk-type camera head 10'3 shown in FIG.
Similar to the cylindrical type, not only does it fall down along the power cable 6, but it is also vulnerable to external pressure and has the disadvantage of being deformed immediately. The camera head 10'4 having a substantially "eight" shape in FIG. 13 (d) has excellent passage of the camera head, but corresponds to various effective space forms in the pipeline 7 as described above. For this purpose, it is necessary to prepare a plurality of detachable adapters 2 'as shown in FIG. To describe an example of a specific size, e.g., diameter 10 in FIG. 15 (a) of a diameter 130mm of the conduit 71 and 15 (b)
The size of the effective space in the pipe is different from that of the pipe 72 of 0 mm, and the adapter 2'1 in the pipe 71 of 130 mm in diameter is different.
Is larger than the opening angle β of the adapter 2′2 in the pipe 72 of 100 mm in diameter, and it does not enter the pipe 72 of 100 mm in diameter by using the adapter 2′1. Adapter 2'2 is required. Therefore, two types of adapters are required, and one type of adapter cannot cope with various effective space forms in the pipeline 7.

Referring to FIGS. 5 (a), 5 (b) and 5 (c), the situation in which the above-mentioned camera head 10 is passed through various diameters of pipes 7 on which cables (power cables) 6 are laid. I will explain. In the illustrated example, the relationship between the diameters of the pipes 7 is as follows.
(B) Diameter of pipeline 71> (b) Diameter of pipeline 72> (c)
And the diameter of the cable 6 is large or small.
(A) Cable 61> (b) Cable 62> (c)
Cable 63. The camera head 10 pushed into the pipe 7 is shown in FIGS. 5 (a), 5 (b) and 5 (c).
As described above, the adapter 2 hangs down following the inner walls of the respective conduits 71, 72, 73 and the outer peripheral surfaces of the respective power cables 61, 62, 63. In this way, the adapter 2 is displaced in accordance with various effective space forms in the pipeline 7 (the size and shape of the space in which the camera head 10 around the power cable 6 in the pipeline 7 can move). Proceed in the pipeline 7. Thus, Adapter 2
Is displaced freely in accordance with the effective space form in the pipeline 7, unlike the conventional simple cylindrical camera head.
There is no danger that the camera head 10 will fall along the twist of the cable 6. In addition, there is no risk of being caught by the step of the joint of the pipeline 7. Therefore, the camera head 10 can move smoothly in the pipeline 7. Further, unlike the conventional spherical camera head, the adapter 2 can be used for a small pipe by reducing the angle of the adapter 2. Further, there is no problem that the camera head is deformed by an external pressure unlike the conventional whisk-type camera head. Since one kind of adapter 2 can cope with various kinds of pipe sizes and cable sizes in pipes as described above, that is, it can cope with various kinds of effective space forms in pipes. It is not necessary to replace an adapter such as a conventional camera head having a substantially "eight" shape, and the workability of inspection in a pipeline is improved.

In such a case, the opening degree of the adapter 2 of the camera head 10 changes in accordance with the laid state of the cable 6 thus changed. It doesn't get stuck.

FIGS. 10 and 11 show another embodiment of the hinge portion 4. FIG. The hinge part 4 of this embodiment is the same as the embodiment of FIGS. 1 to 4 in that a bolt 5 is used, but the right and left adapters 2 face each other by a torsion spring 8 attached to the bolt 5. (In the direction of arrow C) with a relatively weak force. According to this configuration, for example, when the adapter 2 changes the opening angle according to the size of the various cables 6 as shown in FIGS. 5A, 5B, and 5C, and FIG. As shown in (a) and (b), when the laid state of the cable 6 changes, the force of the torsion spring 8 can stably and reliably follow the size of the cable 6.

In each of the embodiments described above, the tip head is a camera head for inspecting the inside of the pipeline. However, the present invention is not limited to this, and an inspection device other than a camera may be attached to the tip of a passage rod. It can be applied to inspections in pipelines, and is not limited to inspections in pipelines. For example, when pushing a line rod into a pipeline to lay a sub duct,
The present invention is also applicable to a case where the wire rod is simply attached to the tip as a guide.

According to the tip head of the present invention, the wing-shaped adapters provided on the left and right sides of the head main body can be turned up and down with respect to the head main body, and can be displaced in accordance with the effective space form in the pipeline. Since it is possible, it is possible to cope with various pipe sizes and cable sizes in the pipes, that is, a variety of effective space forms in the pipes with one kind of adapter. Therefore, it is not necessary to replace the adapter in accordance with various effective space forms in the pipeline, and the operation can be simplified and the efficiency can be improved.
