Rod type automatic moving bent pipe inner wall cleaning device

Abstract

The invention relates to the technical field of steel pipe machining, and discloses a rod type automatic moving bent pipe inner wall cleaning device. The device comprises a base and four outer rods, a fixing device is arranged in the base, a water inlet pipe is fixedly connected to the bottom of the base, and extendable rods are arranged in the outer rods. According to the rod type automatic moving bent pipe inner wall cleaning device, when a bent pipe is cleaned and the cleaning device enters the bent pipe, an inner ball can rotate in an outer ball, the interior of the bent pipe can be cleaned conveniently, bending can be conducted according to the radian of the bent pipe, then the inner wall of a steel pipe can be cleaned, the situation that the interior of the bent pipe is inconvenient to clean is avoided, it is guaranteed that the device can automatically adapt to the radian of the bent pipe, then steel pipes with different bent radians can be cleaned conveniently, and when the steel pipes with the excessively-large bent radians are cleaned, the length of the extendable rod with the proper length should be changed.

Description

technical field [0001] The invention relates to the technical field of steel pipe processing, in particular to a rod-type automatic moving elbow inner wall cleaning device. Background technique [0002] Steel pipes are used to transport fluids and powdery solids, exchange heat, and manufacture mechanical parts and containers. It is also a kind of economical steel. The development of steel pipe production technology began with the rise of the bicycle manufacturing industry, the development of petroleum in the early 19th century, the manufacture of ships, boilers, and aircraft during the two world wars, the manufacture of thermal power boilers after the Second World War, the development of the chemical industry and Drilling, production and transportation of oil and natural gas have strongly promoted the development of steel pipe industry in terms of variety, output and quality. Steel pipes can be divided into two categories according to the production method: seamless steel p...
