Description

  The present invention relates to a rope guide, and more particularly to a rope guide for a rope used for various operations such as a cleaning operation in a pipeline used as a flow path for liquid such as sewage.

  For example, there are various types of pipelines used as liquid channels for sewage and industrial water, but generally they are not thick enough to allow people to enter and perform cleaning and inspection work. . However, various operations such as cleaning and inspection of these pipes are indispensable.

  As what performs various operations, such as a cleaning operation | work and an inspection operation | work in such a thin pipe line, there exists what is proposed by patent document 1, for example.

Japanese Patent Laid-Open No. 5-148886, summary

  The "Underwater robot carrying-in / out device for underdrain water channel cleaning" proposed in this patent document 1 is "fast and accurate in an underwater robot even in a low ceiling underdrain where the ceiling height is close to the length of the underwater robot." It was made for the purpose of proposing an underwater robot carrying-in / out device for cleaning the underwater channel that can be safely carried into and out of the manhole. As shown in FIG. The support frame 2, the guide rails 3 and 4 that extend vertically downward along the wall surface of the upstream end of the support frame 2 and the fistula directly below the manhole, and have a lower end curved in the downstream direction, and the guide rail 3. , 4, a movable curved rail 6 slidably engaged along the curved lower end portion 4, a linear rail 5 installed vertically downward along the wall surface of the downstream end of the support frame 2 and the fistula, Linear Over it equipped with a cable guide 14 for vertically along Le 5 "it is characterized in.

  In other words, in the “underwater robot carrying-in / out device for underdrain water channel cleaning” proposed in Patent Document 1, the “straight rail 5” must be laid down vertically, and along this straight rail 5 The cable guide 14 that moves up and down must be provided, because the underwater robot that performs cleaning in the “underdrain” must be carried in and out of the manhole by the “wire rope 12”.

  However, these “straight rails 5” and “cable guides 14” that move up and down along these lines must be matched to the shape and size of the respective manholes and culverts connected to the manholes. Must be installed every time.

  For example, when looking at the pipelines for sewage, manholes are generally formed at intervals of about 20 m for the multiple connections and inspection in each pipeline, etc. The diameter of the open pipe line may be different. For such a large number of manholes, it is almost impossible to install a fixed “straight rail 5” or “cable guide 14” for each manhole in order to clean and inspect pipes with different diameters. If the “straight rail 5” and the “cable guide 14” are used for each manhole, it will take a considerable amount of time.

  Of course, if the “underwater robot for underdrain water channel cleaning” in a culvert that is installed in a nearly horizontal state is to be pulled out from the outside of a manhole dug vertically by using only the “wire rope 12”, this “wire rope 12” Will be caught at the culvert entrance.

  Therefore, the present inventors can easily install the cable at the opening of the pipeline connected to the manhole, and how can the cable or wire, etc. be easily guided at the opening of the pipeline? As a result of various investigations, the present invention has been completed.

  That is, the first object of the present invention is to provide a cable that can be easily installed at the opening of the pipe as well as being able to guide the rope used for cleaning the pipe at the opening of the pipe. It is to provide a strip guide with a simple configuration.

  A second object of the present invention is to provide a cable guide that can be easily installed even if the size of the opening of the pipe is different.

In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the best mode described below.
