Grinding device easily clamped into inner wall of pipeline

Abstract

The invention discloses a grinding device easily clamped into the inner wall of a pipeline. The grinding device comprises a base. A guiding rod and a threaded rod are mounted on the base, two slidingsleeves are arranged on the guiding rod, and supporting plates are arranged on the upper sides of the two sliding sleeves; a threaded sleeve is connected to the threaded rod in matched and threaded modes, and the threaded sleeve and the sliding sleeves are connected through connecting rods; a lower mounting plate is arranged on the left side of the top of the base, and a plurality of second telescopic cylinders are arranged between the lower mounting plate and the base; an upper mounting plate is arranged above the lower mounting plate, a transverse shaft is further arranged between the uppermounting plate and the lower mounting plate, a plurality of elastic telescopic assemblies are arranged circumferentially on the outer side of a fixing sleeve at the right end of the transverse shaft,and grinding plates are mounted at the outer ends of the elastic telescopic assemblies; and a first telescopic cylinder is further arranged on the right sides of side frames, and a pushing block whichcan push a movable rod leftwards is mounted at the end of the first telescopic cylinder. The grinding device is convenient to operate and control and suitable for grinding different pipelines and hasquite high application and popularization value, and a grinding assembly can be clamped into the pipeline advantageously.

Description

technical field [0001] The invention relates to the field of pipeline processing equipment, in particular to a grinding device for the inner wall of a pipeline that is easy to snap into. Background technique [0002] A pipeline is a 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] During the process of pipeline processing, the inner wall needs to be ground. The existing device is inconvenient to operate and control, and cannot adapt to different pipelin...

AI Technical Summary

Problems solved by technology

[0003] In the process of pipeline processing, the inner wall needs to be ground. The existing device is not convenient to operate and control, and cannot adapt to different pipeline processing needs. The grinding components are not conducive to being stuck in the pipeline, which affects the working efficiency.
