A push type drill pipe inner wall cleaning device and its application method

Abstract

The invention belongs to the technical field of drill pipe cleaning and maintenance and relates to a push-press-type device for cleaning the inner wall of a drill pipe and an application method of thedevice. An annular spray nozzle comprises a columnar pipe and an annular clamping head fixedly sleeving the water outlet end of the columnar pipe, multiple annular spraying holes are evenly distributed at the outer side of the annular clamping head, and multiple press springs are evenly installed on the outer wall of the columnar pipe; a water inlet device is fixedly installed at the water inletend of the columnar pipe, a movable valve is movably clamped to the columnar pipe through a first spring supporting base, and the inner diameter of the press springs is larger than the outer diameterof the columnar pipe and smaller than the inner diameter of the first spring supporting base; the movable valve movably sleeves the annular clamping head through an annular clamping groove, the lengthof the columnar pipe is larger than that of a female connector of the drill pipe to be cleaned, and the length of the movable valve is smaller than that of the columnar pipe. According to the devicefor the cleaning inner wall of the drill pipe, the inner wall of the drill pipe is cleaned before the drill pipe is used for drilling, the cleanness of the drill pipe is improved, the service life ofthe drill pipe is prolonged, and the device helps to improve the working efficiency of drill hole construction.

Description

technical field [0001] The invention belongs to the technical field of drill pipe cleaning and maintenance, and relates to a push-type drill pipe inner wall cleaning device and its use method, in particular to a device that can quickly and effectively clean the remaining rock slag, coal ash and slurry in the inner cavity of the drill pipe. A push-type drill pipe inner wall cleaning device and its application method. Background technique [0002] In recent years, with the rapid development of my country's economy and technology, engineering technology has continued to innovate in the fields of engineering infrastructure and mining. Among them, drilling construction is an important link in the engineering field. The main functions of drilling construction are geological exploration, gas drainage, drilling grouting and oil and gas extraction. Before the drilling process, the cleaning of the drill pipe is often a link ignored by the on-site operators, which is prone to drill bl...

Problems solved by technology

[0004] In view of this, in order to solve the problem that the inner wall of the drill pipe is difficult to clean and not clean in the prior art, the present invention provides a push-type drill pipe inner wall cleaning device and its use method, so that the drill pipe can be cleaned before the drill pipe is drilled. The inner wall is cleaned, which improves the cleanliness of the drill pipe, prolongs the service life of the drill pipe, and is conducive to improving the working efficiency of drilling construction
