Description

[0001] PIPE DETECTION INSTALLATION [0002]

The present invention relates to a pipe detection device, and more particularly, to a pipe detection device having a plate so that when a pipe detection device passes through a branch hole of a pipe, a bearing roller of the pipe detection device is caught by a branch hole, Thereby preventing movement defect and detection defect.

In general, a shock or bump occurs in the process of installing a pipe, and a pipe detection device is used to grasp the deformation degree and deformation position of the pipe due to such impact or impact.

The pipe detection apparatus 10 generally used is a system in which the detection discs 12 made of a material (for example, aluminum) that can be easily bent as shown in FIGS. 1 and 2 are spaced apart from each other It is placed on both sides. The outer diameter of the detection disk 12 is formed so as to be substantially equal to the inner diameter of the pipe S or close to the inner surface of the pipe S.

Particularly, the detection disc 12 is provided with a cutout groove 14 partially cut from the tip toward the center along the tip of the detection disc 12, and the cutout groove 14 cuts the cutout segment 12 16 are partitioned.

A steel disc 18 having a diameter smaller than the outer diameter of the detection disc 12 is disposed in close contact with a surface of the detection disc 12 to prevent the detection disc 12 from being totally deformed. The base plate 20 is fastened and fixed between the base plates 20 in a state in which the base plate 20 is disposed on both sides so as to be engaged between the base plate 12 and the steel disc 18.

A ring member 22 is fixedly connected to the center of the inner surface of the detection disc 12 and a connection ring member 24 is disposed between the ring members 22. The connection shaft 26 is coupled through the detection disc 12 and the ring member 22 and the connection ring member 24, respectively. At this time, the connecting ring member 24 may be coupled so that movement along the connecting shaft 24 can be performed.

The first link 30 connected to the rib 28 of the ring member 22 and the second link 34 connected to the rib 32 of the connecting ring member 24 are connected by a hinge shaft 36 And a bearing roller 38 which is moved along the inner surface of the pipe S is also rotatably coupled to the hinge shaft 36. [

Therefore, the pipe detecting apparatus 10 is received at one end of the piping S having been installed, and the pipe detecting apparatus 10 is moved in the direction of the arrow. At this time, the bearing roller 38 also moves along the pipe S while being in contact with the inner surface of the pipe S. At this time, for example, when the deformation protruding in the inward direction on the pipe S is encountered, the detecting disk 12 of the pipe detecting device 10 is caught. If the user continues to move in the direction of the arrow in the state where the jamming has been performed, the jawed cutting segment 16 of the cutting segment 16 of the detection disk 12 is bent so that the cutting segment 16 It is possible to comprehensively grasp the degree of bending, the position of the incision segment 16, the movement length of the pipe detection device 10, and the like, thereby confirming the damage and deformation position of the pipe S.

When there is a possibility that the branch pipe is to be connected later from the pipe S, the branch pipe P is pierced in the pipe S and the T pipe adapter T normally used in the branch pipe P is connected . When the branch pipe P is formed in the pipe S as described above, when the pipe detecting device 10 passes the branch pipe P, the bearing roller 38 is pulled into the branch pipe P, It is impossible to move the pipe detection device 10 so that the detection operation for the pipe S can no longer be performed and the pipe detection device 10 must be taken out of the pipe S A troublesome work is generated.

According to the present invention, when a plate is provided in the pipe detection device and the bearing roller passes the branching hole, the movement defect of the pipe detection device due to the engagement of the bearing roller and thus the detection failure is prevented, And to provide a pipeline detection device that can solve the problem.

According to the present invention, there is provided a pipe detection device that moves along the inside of a pipe, comprising: a detection disk disposed at a distance from each other in a state of facing each other; A ring member fixedly connected to the inner surface of the detection disk; A connecting ring member disposed between the ring members; A connection shaft which is coupled to the detection disc through the ring member and the connection ring member, respectively; And a plate coupled in the longitudinal direction of the bearing roller and the pipe coupled to the hinge shaft connecting the first link of the ring member and the second link of the connecting ring member.

As described above, according to the present invention, the hinge shaft connecting the first link of the ring member and the second link of the connecting ring member is provided with the plate in the longitudinal direction of the pipe, so that, when passing through the branch hole, It is possible to expect the effect of preventing the movement of the pipe detection device and hence the detection failure and also the effect of eliminating the hassle of the detection operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 3 is a cross-sectional view schematically showing the inside of a pipe by using the pipe detecting apparatus according to the present invention, and FIG. 4 is a sectional view taken along line B-B of FIG. Prior to the description of the present invention, the same components as those of FIG. 1 are denoted by the same reference numerals and will not be described in order to avoid redundant description.

1 and 2, the pipe detection device 50 according to the present invention has a structure in which the detection disk 12 is disposed on both sides and the detection disk 12 is connected by the connection shaft 26 have. At this time, the connection shaft 26 is coupled with the ring member 22 connected to the center of one surface of the detection disc 12 and the connection ring member 24 disposed between the ring member 22 do.

The first link 30 connected to the rib 28 of the ring member 22 and the second link 34 connected to the rib 32 of the connecting ring member 24 are connected to each other by a hinge shaft (36). A bearing roller 38 is also rotatably coupled to the hinge shaft 36.

Here, the plate 52 having a length is coupled to the hinge shaft 36 for connecting the first link 30 and the second link 34 to each other. The plate 52 is formed in the shape of a pear shape formed by the curved portions 54a and 54b at both end sides and is fixed in the longitudinal direction of the pipe S.

Therefore, when the pipe detecting device 50 of the present invention is passed through the branch hole P of the pipe S, the bearing roller 38 is pulled into the branch hole P, The bearing roller 38 is prevented from falling into the branch hole P because the support roller 52 is supported by the branch pipe P across both sides of the branch pipe P, Can be prevented.

For example, even if the pipe detection device 50 is slightly tilted, and the curved surface portion 54a, which is one end of the plate 52, comes into contact with the branch hole P, the curved surface portion 54a The plate 52 can easily come out from the branch hole P. [ As a result, not only the movement defect of the pipe detection device 50 can be prevented, but also the detection failure can be prevented. That is, it is possible to solve the trouble of the detection operation which has been caused by the engagement of the pipe detection device 50 in the related art.
