An automatic polishing machine for the outer wall of a pipe

Abstract

The invention discloses an automatic polishing machine for the outer wall of a pipeline, which comprises an arc-shaped first polishing arm and a second polishing arm, the two ends of the first and second polishing arms are respectively connected, and the connected first and second polishing arms have angle; the first and second polishing arms include a polishing device and a walking device. The first and second polishing arms of the present invention are easy to disassemble, and the overall structure is simplified; a single polishing arm is small in size and easy to carry after disassembly, and is suitable for outdoor pipeline engineering polishing operations, especially for pipeline polishing with complex field terrain and small working space .

Description

technical field [0001] The invention relates to a polishing machine, in particular to an automatic polishing machine for the outer wall of a pipeline, which belongs to the technical field of steel pipe processing equipment. Background technique [0002] There are many methods for removing rust on the outer surface of steel pipes. There are basic manual rotary tool grinding, which is very inefficient, and there are also efficient rust removal methods such as shot blasting and sand blasting. There are also many patent designs related to rust removal, such as patent No. ZL201711122118.1 is a rust removal system for the outer surface of steel pipes. When the rust is removed, the equipment does not move, the steel pipe rotates, and the equipment is large. These rust removal methods are not suitable for rust removal on the outer surface of pipelines that have been installed in place, such as a large number of chemical pipelines. At present, manual rotary tool grinding is usually u...

Problems solved by technology

[0002] There are many ways to remove rust on the outer surface of steel pipes. There are basic manual rotary tool grinding, which is very inefficient. There are also efficient rust removal methods such as shot blasting and sand blasting. There are also many patented designs for rust removal, such as patent No. ZL201711122118.1 is a steel pipe outer surface rust removal system. During the rust removal, the equipment does not move and the steel pipe rotates. The equipment is large in size

These derusting methods are not suitable for derusting the outer surface of pipelines that have been installed in place, such as a large number of chemical pipelines. At present, manual rotary tool grinding is usually used, which has very limited effect, heavy workload, and is easy to cause damage to the steel pipe body.
