[0018] Example:

[0019] like Figure 1 to Figure 3 As shown in the figure, the clamp ring for the outer wall of the drill pipe includes a fixed seat 1, and the upper end of the fixed seat 1 is provided with a fixed plate I2 with a circular arc structure. II4 is connected, the ends of the fixed plate I2 and the fixed plate I2 are respectively provided with a convex plate I21 and a convex plate II41 that cooperate with each other. The threaded through hole I and the threaded through hole II are matched with the tightening structure 5 provided with the screw. The convex plate I21 is connected with the fixed frame 9 through the rotating shaft I. The end of the fixed frame 9 is matched with the screw I10. The screw holes of the screw I10 are matched with each other, and the inner walls of the fixed plate I2 and the fixed plate II4 are respectively provided with grooves I6 and II. The side walls of the grooves I6 and II are respectively provided with lugs I7 and lugs II. , the gr...

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...
