Abstract

The invention relates to a clamp type drill rod outer wall clamping ring which comprises a fixing seat. The upper end of the fixing seat is provide with a fixing plateIwith an arc structure. One end of the fixing plateIin the radial direction is connected with a fixing plateIIof the arc structure through a rotating shaft, the end portions of the fixing plateIand the fixing plateIIare provided with a protruding plateIand a protruding plateIIwhich are matched with each other respectively, the protruding plateIand the protruding plateIIare provided with a screw thread through holeIand a screw thread through holeIIwhich are matched with each other and matched with a screw down structure provided with a screw, the inner walls, matched with each other, of the fixing plateIand the fixing plateIIare provided with a grooveIand a grooveIIrespectively, the side walls of the grooveIand the grooveIIare provided with a protruding pieceIand a protruding pieceIIrespectively, a rubber plateIand a rubber plateIIare arranged in the grooveIand the grooveIIrespectively, and the side walls of the rubber plateIand the rubber plateIIare provided with a clamping grooveIand a clamping grooveIIwhich are matched with the protruding pieceIand the protruding piece II. According to the clamp type drill rod outer wall clamping ring, a clamp type fixing method is used to fix a petroleum drill rod, manual operation is performed, and the problems of high energy consumption and high cost caused by hydraulic type fixing are solved.

Description

technical field [0001] The invention relates to the field of fixing devices, in particular to a clamping ring for clamping the outer wall of a drill pipe. Background technique [0002] In the process of oil extraction, the drill pipe is an indispensable tool. The drill pipe can be used repeatedly. In order to improve the service life of the drill pipe, the drill pipe must be maintained and cleaned after each use. During the use of the drill pipe, the mud, stone chips, oil stains and other debris generated by drilling will adhere to the outer wall of the drill pipe, corrode the outer wall of the drill pipe, affect the service life of the drill pipe, and damage the drill pipe. The next use of the drill pipe will affect the quality and work efficiency of the next drilling. Therefore, the drill pipe must be cleaned after use, because the drill pipe used in petroleum machinery The diameter of the drill pipe is relatively large, so it is necessary to fix the drill pipe with a fi...
