Description

The apparatus of repairing pipe

The present invention relates to a sewage pipe maintenance apparatus, which will be described in more detail. The apparatus for removing various precipitates or depositing foreign matters on the inner wall is rotated by the rotational force of the grinding tool, or the wheel is in close contact with the inner wall. The present invention relates to a sewer pipe maintenance device that is developed to solve the problem that back and forth is difficult to move forward and backward in a stable posture, so that the grinding tool rotates to remove deposits.

Unlike water pipes, unlike sewage pipes, various foreign substances are contained, so once the heavy material is settled, the sewage flow slows down and the sedimentation continues, providing the cause of sewage backflow.

In particular, in the case of large pipelines, it is common to remove them by manpower, but in the case of small sewage pipes ranging from general households to large pipelines, it is impossible to clean them due to the input of manpower. One had that limit.

Recently, a sewer pipe maintenance device operating in a wired line has been developed so that it is possible to enter and clean a narrow sewer pipe so that maintenance of the sewer pipe, which is relatively difficult to maintain compared to large sewer pipes, is relatively easy.

However, the sewer pipe maintenance device is intended to remove deposits and deposits by grinding tools that are driven and rotated for the wheels, but when the grinding tools are not rotated by solid deposits, the rotation is transmitted to the main body where the wheels are mounted. There is a problem that the main body is rotated and thus the sedimentation and the removal of deposits are not easily made or twisted to allow power supply and adjustment to the main body.

In addition, it is moved by three to six wheels in the lower part, but internal sedimentation and deposits may become obstacles, and some parts of the wheels are not in close contact with the inner wall surface due to the rotation of the grinding tool, so it is impossible to move forward and backward. There was a problem that occurred.
