no. 1 approach

[0033] The first embodiment of the present invention relates to a device for quickly judging the wear of a drill thread, such as figure 1 As shown, it at least includes a keychain 8, and a mobile light source 2, a reflector 4, and a buckle gauge box 9 mounted on the keychain 8; a plurality of buckle gauges 1 of different specifications are housed in the buckle gauge box 9; The top of the buckle gauge 1 is provided with threaded teeth for meshing with the screw thread of the drilling tool, and the moving light source 2 is connected to one side of the buckle gauge 1, such as figure 2 As shown, the other side of the buckle gauge 1 opposite to the moving light source 2 is marked with a comparison Figure 5 and the scale line 6; when the night falls, the light is dim or the sight is not good in rainy and foggy weather, the brightness of the mobile light source 2 is automatically adjusted according to the brightness of the external working environment, and the light of the mobile l...

no. 2 approach

[0039] The second embodiment of the present invention relates to a device for quickly judging the wear of a threaded thread of a drilling tool, including a key chain 8, a moving light source 2, a clamping structure 3, a reflector 4, and a buckle gauge box 9. There are a plurality of buckle gauges 1 of different specifications, and the top of the buckle gauge 1 is provided with thread teeth for meshing with the screw thread of the drilling tool. The mobile light source 2 is connected to the buckle gauge 1 through the clamping structure 3, The other side of the buckle gauge 1 opposite to the moving light source 2 is marked with a comparison Figure 5 And the scale line 6; when the light of the moving light source 2 passes between the buckle gauge 1 and the threaded thread, the wear of the threaded thread of the drilling tool can be judged by observing the matching gap between the two. The buckle gauge box 9, moving light source 2, clamping structure 3, reflector 4, etc. can all ...

no. 3 approach

[0045] The third embodiment of the present invention relates to a device for quickly judging the wear of a threaded thread of a drilling tool, including a key chain 8, and a mobile light source 2 mounted on the key chain 8, a clamping structure 3, a reflector 4 and a key chain. A gauge box 9, the buckle gauge box 9 is equipped with a plurality of buckle gauges 1 of different specifications, and the top of the buckle gauge 1 is provided with thread teeth for meshing with the screw thread of the drilling tool, and the mobile light source 2 It is connected to the buckle gauge 1 through the clamping structure 3, and the other side of the buckle gauge 1 opposite to the moving light source 2 is marked with a comparison Figure 5 And the scale line 6; when the light of the moving light source 2 passes between the buckle gauge 1 and the threaded thread, the wear of the threaded thread of the drilling tool can be judged by observing the matching gap between the two.

Abstract

The invention provides a device for quickly judging wearing of a screw thread of a drilling tool and a method. The device at least includes a key chain, a mobile light source in hooked connection withthe key chain, a reflective mirror, and a button gauge box; and button gauges of different specifications are placed inside the button gauge box, and are used for quickly judging wearing and discarding conditions of a male screw thread and a female screw thread. When detection is performed, the screw thread is first cleaned, for the male screw thread, the button gauges are tightly attached to thescrew thread, a light shape exposed from an engaging part of the button gauges and the screw thread is observed, the number of sharpening teeth is determined according to a comparison chart and a scale line on the button gauges, thereby determining the wearing condition of the male screw thread; and when it is necessary to detect the female screw thread, the reflective mirror is additionally utilized, the mobile light source on one side of the button gauges is first opened, an operator observes the light shape exposed from the engaging part of the button gauges and the screw thread through the reflective mirror, and according to the comparison chart and the scale line on the other side of the button gauges, the wearing condition of the female screw thread is determined. The method has theadvantages of convenient usage, high efficiency, low labor intensity, safe and convenient operation, and the like.

Description

technical field [0001] The invention belongs to the technical field of pipe tools for drilling engineering machinery, and in particular relates to a device and method for quickly judging the wear of threaded threads of drilling tools. Background technique [0002] The drilling team needs to use drilling tools for drilling operations during construction. Drilling tools include drill collars, drill pipes, mating joints and various downhole tools. The connections between them are all connected by threads, and each short joint is about 0.5 -10 meters or so; during drilling construction, it is necessary to load and unload each single short joint many times, and the thread of the drilling tool will also wear out; the weight of the drilling tool increases with the increase of the well depth, which can reach tens to hundreds of tons , The wear and tear of the drilling tool thread will cause the drilling tool to trip and fall into the drilled well, causing a safety accident.
