Description

The present invention relates to an introduction device for introducing a traveling vehicle or the like into a pipe line connecting a plurality of manholes .

The pipeline connecting multiple manholes must be inspected immediately after laying is completed, especially in the interior. For example, during use as a sewer, maintenance such as inspection and cleaning inside the pipeline is required. There is a need to do. If this pipe is large enough for a person to enter, maintenance can be performed by a person, but if it is a small diameter pipe that cannot be inserted by a person, It is impossible for a person to do directly.

  In general, when performing maintenance or the like in a pipeline that does not allow such a person to enter, as shown in FIGS. 12 to 15, wires and auxiliary ropes are connected from one manhole to the corresponding pipeline. A traveling vehicle is introduced, and a camera and a cleaning tool are reintroduced into the pipeline using wires and auxiliary ropes coming out from other manholes.

  As a means for performing maintenance or the like in the corresponding pipe line by such a method, for example, there is one proposed in Patent Document 1 or the like.

Japanese Patent Laid-Open No. 5-148886, abstract, representative diagram

  The “Underwater robot carrying-in / out device for underdrain waterway cleaning” proposed in this patent document 1 “makes an underwater robot fast and accurate 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 loading / unloading device that can be safely carried in and out of manholes, as shown in FIG. The support frame 2 provided, guide rails 3 and 4 extending vertically downward along the wall surface of the upstream end of the support frame 2 and the fistula directly below the manhole, and having a lower end curved in the downstream direction, and the guide rail A movable curved rail 6 slidably engaged along the curved lower end portions 3 and 4, and a linear rail 5 laid down vertically along the wall surface of the downstream end of the support frame 2 and the fistula ,the above And "in which comprises a cable guide 14 for vertically along a linear rail 5.

  This “Underwater Robot Carrying In / Out Device for Cleaning Underwater Channels” disclosed in Patent Document 1 “allows underwater robots to be quickly, accurately and safely even in low ceilings where the ceiling height is close to the length of the underwater robot. It is thought that it can be carried into and out of the manhole ”, but“ a guide rail that extends vertically downward along the wall surface of the upstream end of the support frame 2 and the fistula directly below the manhole and has a lower end curved in the downstream direction. 3 and 4 ", the entire configuration is complicated by at least the" guide rails 3 and 4 ", and the installation work of the" guide rails 3 and 4 "is also required.

  In particular, as described above, thin pipes that cannot be inserted by people have been used frequently in recent years, and because they are connected to one manhole in different heights, patents There is no room or space where the “guide rails 3 and 4” as in Document 1 can be used. In other words, as shown in FIG. 12, in the present situation where a pipe having an inner diameter enough to be finally inserted by a robot or a traveling vehicle is being adopted, even if “guide rails 3 and 4” are adopted, this is used. The number of cases that cannot be increased is increasing.

  Also, for example, when an auxiliary cable passed through the pipeline with a traveling vehicle is used to pull the tow cable attached with a cleaning tool into the pipeline, the tow cable opens into the manhole. There are cases where the end of the pipeline is caught and cut, or the end of the pipeline is damaged by the towing line. If the pipe end is damaged, the inspection will not pass, and a considerable cost will be required including re-working.

Therefore, the present inventors have a simple configuration and easy operation for this kind of introducing device for introducing a traveling vehicle or the like into a pipe line connecting a plurality of manholes. As a result of various investigations, the present invention has been completed.

  That is, the object of the present invention is not only that the structure is simple and the work can be easily performed, but it is connected to a single manhole in different heights, and the inside of a pipe line that is so thin that a person cannot enter it. Even so, an object of the present invention is to provide an introduction device capable of introducing a traveling vehicle or the like. Moreover, the place made into the objective of this invention is providing the introduction apparatus with which damage to a pipe line end part does not generate | occur | produce by the auxiliary | assistant rope to be used or the tow rope.

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.
“Introducing device 10 for introducing the traveling vehicle 30 into the pipeline 41 connecting the plurality of manholes 40 ,
An introduction rod 11 inserted into one of the manholes 40, an introduction body 12 connected to the introduction rod 11 so as to be adjustable in position, and a support base 13 for the traveling vehicle 20 connected to the lower portion of the introduction body 12. Introducing device 10 for a pipeline traveling vehicle characterized by comprising:
It is.

That is, as shown in FIGS. 1 to 3, the introduction device 10 according to claim 1 introduces the traveling vehicle 20 into the underground conduit 41 from above the manhole 40, It is intended or to introduce a traction rope 31 for cleaning tools 30 using, an introduction rod 11 which is inserted into one of the manhole 40 is positioned adjustably connected to this introduction rod 11 An introduction body 12 and a support base 13 for the traveling vehicle 20 connected to the lower portion of the introduction body 12 are provided.

  The introduction rod 11 is for the operator to insert the traveling vehicle 20 attached to the lower end portion into the manhole 40 and is not particularly limited to the structure as long as the traveling vehicle 20 can be mounted. Although not described later, in the embodiment described later, it is composed of an outer flange 11a and an inner flange 11b each having a locking hole 11c.

  The introduction main body 12 may be anything as long as it can be attached to the lower end portion of the introduction rod 11 so that the position of the introduction main body 12 can be adjusted. However, in the embodiment described later, a locking block 16 that is locked in the locking hole 11c of the introduction rod 11 is provided. The introduction main body 12 is provided with a support base 13 for mounting and mounting the traveling vehicle 20 thereon.

  The support base 13 is configured such that a traveling vehicle 20 as shown in FIG. 12 can be mounted on the upper surface, and is connected to the introduction main body 12 at the base. Of course, the support base 13 is substantially orthogonal to the introduction rod 11 and can support the traveling vehicle 20 horizontally when the introduction rod 11 is set up vertically. Further, as shown in FIG. 4, the tip of the support base 13 is opened so that the mounted traveling vehicle 20 can travel toward the pipe line 41 without any trouble.

  In order to use the introducing device 10 configured as described above, first, when the pipe 41 into which the traveling vehicle 20 is to be introduced does not open at the same position as the bottom surface 42 as shown in FIG. The introduction rod 11 that is not mounted is inserted into the manhole 40, and the position of the support base 13 is visually checked when the lower end of the introduction rod 11 reaches the bottom surface 42 of the manhole 40. Then, the position of the support 13 in the pipeline 41 where the traveling vehicle 20 is to be introduced is adjusted with respect to the introduction rod 11 standing on the ground so as to match the position shown in FIG. Then, the traveling vehicle 20 is mounted on the support base 13 and the introduction rod 11 is inserted into the manhole 40 as it is.

  At the time of this insertion, the auxiliary rope 21 is connected to the traveling vehicle 20 and the traveling vehicle 20 is in a driving state, that is, a state where the wheels are rotating. The traveling vehicle 20 is mounted on the support base 13 so that the wheels can idle. Then, when the support base 13 is located at the entrance of the pipeline 41, the wheel touches the bottom surface 42, or it touches a part of the pipeline 41 by slightly shaking the entire introduction device 10. The car 20 automatically starts running into the pipeline 41, that is, is introduced.

  Here, the traveling vehicle 20 itself is of a type that is equipped with a camera that can capture an image of the inside of the pipeline 41 as shown in FIGS. 12 and 13 and that can send the image data to an external monitor. For example, even if the pipe 41 has an inner diameter that a person cannot enter, the situation inside the pipe 41 can be checked on the ground. The traveling vehicle 20 that has been checked can be pulled back to the original position by pulling the auxiliary rope 21.

  Alternatively, when the traveling vehicle 20 reaches another manhole 40, it hits the inner wall or falls on the bottom surface 42 and stops, so that the traveling vehicle 20 is pulled up using, for example, the introduction rod 11. Therefore, it is convenient to provide a “claw claw” that engages with the traveling vehicle 20 on the side opposite to the side where the introduction body 12 of the introduction rod 11 is attached.

  In addition, since the auxiliary rope 21 is connected to the traveling vehicle 20 that has entered the pipeline 41, the traveling vehicle 20 draws the auxiliary rope 21 into the pipeline 41. And when this traveling vehicle 20 reaches another manhole 40, it hits the inner wall or falls on the bottom surface 42 and stops, so if this traveling vehicle 20 is pulled up, the auxiliary rope 21 connected to it. Is pulled out from another pipe 41. Therefore, if the tow rope 31 is connected to the auxiliary rope 21 and the auxiliary rope 21 is pulled out from the original manhole 40 (manhole 40 on the side where the traveling vehicle 20 is inserted), the tow rope 31 is To the manhole 40 side. Therefore, if the cleaning tool 30 illustrated in FIG. 15 is connected to the tow rope 31 and the end portion of the tow rope 31 on the other manhole 40 side is pulled out using, for example, a winder 50 or the like. The cleaning tool 30 cleans the inside of the pipe line 41.

As a result of the above, for example, as shown in FIGS. 1 and 2, even if a plurality of pipelines 41 are connected to one manhole 40 at different heights, the introduction main body 12 or the support base 13 can be attached to the introduction rod 11 By adjusting the position, the traveling vehicle 20 can be introduced into the plurality of pipelines 41 in one manhole 40. Moreover, since the introduction device 10 can be operated from the ground, the traveling vehicle 20 and the like can be introduced even in the pipe line 41 that is so thin that a person cannot enter it.

  Accordingly, the introduction device 10 according to the first aspect of the present invention is simple in structure and easy to operate, and is connected to a single manhole 40 at different heights and is so thin that a person cannot enter it. Even within the road 41, the traveling vehicle 20 or the like can be introduced.
