Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning and drilling technology, and in particular to a pipeline drilling and reaming cleaning system and a pipeline drilling and reaming cleaning robot. Background Art

[0002] Currently, drilling refers to the collective term for machinery and equipment that uses tools harder and sharper than the target object to leave cylindrical holes or cavities in the target object through rotary cutting or rotary extrusion. It plays a very important role in industrial production. Pipeline cleaning robots typically consist of a drilling / reaming cleaning mechanism, a control mechanism, and a moving mechanism. By enabling the robot's moving mechanism to carry or connect to the corresponding drilling / reaming cleaning mechanism, it can move and clean inside the pipeline, thereby achieving the detection and cleaning of the pipeline's interior and thus unblocking the pipeline.

[0003] In the process of developing this utility model, the inventors discovered the following problems in existing related technologies: In industrial production, pipes accumulate dirt and scale after operating for a period of time. If not cleaned in time, this can cause damage such as corrosion, cracks, dents, or deformation. Due to the confined space inside pipes, manual cleaning is often impossible, requiring pipe cleaning robots to perform the cleaning work. Currently, most drill bits on the market are unidirectional, making it difficult to clean hard dirt from the inner wall of pipes, and they are prone to getting stuck inside the pipe, making them unsuitable for front-mounted installation.

[0016] The advantages and positive effects of this utility model are as follows: This utility model provides a pipe drilling and reaming cleaning system.

[0048] Please see Figures 5 to 6 The installation and connection sequence is as follows: the stepped drill bit 1 is installed at the front end of the first mounting base 26 and fixed to the first mounting base 26 by bolts 12; both the first and second mounting bases are provided with flanges 10, and the flanges 10 are provided with non-through embedded grooves 28 on their circumference. The embedded grooves 28 are provided with three side walls and a groove bottom; the side walls parallel to the end face of the flanges 10 are provided with threaded holes; the inner rings of the first and second driven gears are provided with protrusions that mate with the embedded grooves 28.

After starting, when the industrial camera 11 detects a blockage in the pipe ahead, the second motor 3 drives the second drive gear 6 to rotate, and the second driven gear 7 drives the second mounting base 9 to rotate around the base 23; the first motor 2 drives the first drive gear 4 to rotate, and the first driven gear 5 drives the first mounting base 26 to rotate around the second mounting base 9; causing the stepped drill bit 1 to rotate accordingly, forming a ring drill / reamer trajectory to drill through the blockage in front. When the industrial camera 11 does not detect a blockage, the stepped drill bit 1 and the first and second motors will stop rotating to save energy and protect the equipment's lifespan. When the transparent glass in front of the industrial camera 11 is contaminated by pipe dirt, the glass wiping assembly starts to operate, and the lifting gear 13 moves up and down along the rack 14, driving the cleaning brush 19 to move up and down to clean the dirt on the transparent glass cover 17. The pollutants and wastewater will be diverted to the collection box 18 below for later collection and discharge.
