Petroleum drill pipe joint wooden packaging box based on smooth surface side rolling principle

Abstract

The invention discloses a petroleum drill pipe joint wooden packaging box based on the smooth surface side rolling principle. The petroleum drill pipe joint wooden packaging box structurally comprisesa side rolling device, a sealing cover plate, fixing clamps, a loading box body, bottom frames and two or more fastening bars. The two or more fastening bars are mounted at the four corners of the side face of the loading box body in a buckled mode. The two ends of the bottom of the loading box body are connected with the bottom frames in a buckled mode. The upper ends of the bottom frames are buckled to grooves of the fixing clamps. When a drill pipe joint needs to be taken out, the petroleum drill pipe joint wooden packaging box can guide a petroleum thinner in through a filling mechanism to enable the petroleum thinner to be diffused in a purifying cotton brush. At the moment, an inner spindle rotates to drive a rolling wheel, the drill pipe joint is turned over, and the purifying cotton brush is used in cooperation to brush away oil stain. Accordingly, it is ensured that the surface of the drill pipe joint is clean when the drill pipe joint is taken out to prevent the situation that residual oil stain causes hand slipping and has the effect on carrying.

Description

technical field [0001] The invention relates to the field of wooden packaging boxes, in particular to a wooden packaging box for oil drill pipe joints based on the principle of side milling smooth surfaces. Background technique [0002] The oil drill pipe joint is the butt joint with the drill pipe body used in oil and natural gas drilling operations, including internal and external threaded joints. The oil drill pipe friction welding process is quite brittle, so it is generally necessary to pass through the weld seam during processing. Heat treatment is used to improve its performance, thereby improving the quality and life of the joint, and it is easy to wear the joint surface during the joint replacement and adjustment process during use. Therefore, the outer wall surface of the joint is rough, and oil is easy to absorb. Usually, the replaced drill pipe The joints will be stored in wooden packing boxes to improve the convenience of handling. There is such a problem in th...

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a wooden packaging box for oil drill pipe joints based on the principle of side milling smooth surface, so as to solve the problem that the original rough surface is damaged by residual oil when the oil drill pipe needs to be taken out. Adsorption, and it is not easy to clean and remove in the packing box, resulting in easy hand slipping during the moving process, difficult to take out, and high risk problems
