Description

Technical Field

[0001] The invention relates to the technical field of pipeline cleaning and drilling processing, and in particular to a pipeline drilling and reaming cleaning system and a pipeline drilling and reaming cleaning robot. Background Art

[0002] At present, drilling refers to the general term for machinery and equipment that uses a tool that is harder and sharper than the target object to leave a cylindrical hole or hole on the target object through rotary cutting or rotary extrusion. It plays a very important role in industrial production. Pipeline cleaning robots are usually composed of a drilling / reaming cleaning mechanism, a control mechanism, and a moving mechanism. The robot's moving mechanism carries the corresponding drilling / reaming cleaning mechanism, or is connected to the drilling / reaming cleaning mechanism, and moves and cleans in the pipeline, so that the inside of the pipeline can be inspected and cleaned, thereby unblocking the pipeline.

[0003] In the process of realizing the present invention, the inventors found that the existing related technologies have the following problems: In industrial production, the pipeline will accumulate dirt and scale after running for a period of time. If it is not cleaned in time, it will cause damage such as corrosion, cracks, dents or deformation. Due to the small space inside the pipeline, manual cleaning is impossible in most cases, and a pipeline robot is required to complete the cleaning work. At present, most of the drill bits on the market are single-directional, which is difficult to drill hard dirt on the inner wall of the pipeline, and it is easy to get stuck in the pipeline, which is not suitable for front installation.
