Self-propelled oil pipeline automatic paint removing and grinding device and grinding method thereof

Abstract

The invention discloses a self-propelled oil pipeline automatic paint removing and grinding device and a grinding method thereof. The device comprises a rack, a motor is arranged on the rack, the motor is connected with a motor rotating shaft extending forwards, a small belt wheel is arranged on the motor rotating shaft, and the small belt wheel and a second double-flange belt wheel are connected through a sleeved transmission belt. A tensioning wheel is arranged outside the transmission belt. The second double-flange belt wheel and the first double-flange belt wheel are connected in series and fixed to a first fixing device and a second fixing device through threaded connecting rods, the first fixing device and the second fixing device are of annular structures, and the upper half parts of the first fixing device and the second fixing device are connected with the rack. A gear box is installed below the rack and connected with a land wheel shaft below the rack through a second chain wheel set on a side shaft, and land wheels are installed on the land wheel shaft. The device is simple in structure and detachable, automatic polishing and automatic advancing along a pipeline can be achieved, manpower is replaced with electric power and mechanical force, and the polishing efficiency can be greatly improved by matching with the given polishing method.

Description

technical field [0001] The invention relates to the field of pipeline paint removal and polishing devices, in particular to a self-propelled oil pipeline automatic paint removal and polishing device and a polishing method thereof, which can realize paint removal and polishing on the outer wall of the pipeline. Background technique [0002] Since the 1970s, the oil and natural gas industry has developed rapidly, and pipeline transportation has been widely used as an important transportation method. However, during the transportation process, because most of the pipelines are located in the wild, and the surrounding environment is complex and harsh, leaks and cracks will inevitably appear in the pipelines. In order to detect whether the pipeline is damaged by corrosion, it is usually necessary to regularly remove the paint and polish the surface of the pipeline to ensure the detection accuracy. However, most of the current paint removal and polishing work is completely done m...
