Handheld pipeline groove bionic polishing device

Abstract

The invention discloses a handheld pipeline groove single-face polishing device which comprises a power device, a polishing device body and a tight-supporting device. The power device is fixedly connected with the tight-supporting device through a fixing pipeline. A rotating shaft I is arranged on the fixing pipeline in a sleeving mode and connected with the polishing device body through a bracket. The power device is in driving connection with the rotating shaft I. The polishing device body comprises a frame, a movable plate I, a movable plate II, a polishing piece, an inflation pipe I and two airbags I. The polishing device body is partially fixed to the rotating shaft and can rotate along with the rotating shaft to form revolution, and in this way, a pipe orifice of the whole pipeline can be polished at a time; through an adjustable telescopic rod arranged at the front end of a transverse rod, the polishing assembly can extend and retract in the front-rear direction, and the applicable range is expanded; and the bracket further be positioned in an up-down extending and retracting mode, and the revolution diameter of a polishing assembly is increased, so that the handheld pipeline groove single-face polishing device is applied to different pipeline diameters, and practicability and universality are improved.

Description

technical field [0001] The invention relates to a hand-held pipe groove bionic grinding device. Background technique [0002] Pipeline refers to the device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. [0003] In the construction of pipeline engineering, different connection methods should be selected according to the material of the pipe used. Ordinary steel pipes are threaded, welded and flanged; seamless steel pipes, non-ferrous metals and stainless steel pipes...

AI Technical Summary

Problems solved by technology

On the other hand, the uncertainty of parameters such as the diameter and wall thickness of the pipe increases the difficulty of grinding the pipe joint.

[0005] At this stage, large-scale grinding machines are not suitable for small places, and small-scale grinding machines are unstable. Skilled workers must be required to properly improve the stability. At present, most of the pipe joints still rely on manual grinding, but whether manual grinding is Time, efficiency or quality are not optimistic

There are a series of problems such as uneven grinding and different groove sizes, and it is difficult to ensure the consistency of the pipe grinding interface, which affects the strength after welding. These are the problems of manual grinding that are difficult to solve at present.
