[0001] The utility model relates to the technical field of drilling equipment, in particular to a semi-automatic impact testing device for drilling rod strength detection. Background Art

[0002] Drilling equipment refers to equipment used for drilling, including a complete set of ground equipment for drilling, special drilling tools and drilling instruments, etc. The drill pipe is a steel pipe with a threaded tail, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or bottom hole device at the bottom of the drilling rig. During the production of the drill pipe, an impact test device will be used to test its strength.

[0003] Authorization announcement No. CN212110913U discloses a device for detecting the strength of an oil production drill pipe, which can increase the adjustment stroke of the support mechanism, thereby reducing the probability of the oil production drill pipe or other objects to be tested being too large to measure the torsional strength through the strength detection device, thereby improving the functionality of the strength detection device; it includes a body, a power mechanism and a support mechanism, the power mechanism is installed on the left side of the top of the body, the bottom end of the support mechanism is provided with a slide rail assembly, and the front end of the power mechanism is provided with a display assembly and a control assembly; it also includes a controller, a slider, a rotating shaft, an adjusting threaded rod and an adjusting handwheel, the bottom end of the controller is connected to the right side of the top of the body, the top of the controller is provided with a control groove, the right end of the control groove is penetrated by an insertion hole, and the insertion hole is fitted with a bearing in the left area of ​​the rotating shaft.

[0004] Existing drill pipe strength testing devices for oil production have shortcomings: they rely on the position of the support mechanism and control the power mechanism through a control assembly to coordinate the power mechanism with the support mechanism to test the torsional strength of the drill pipe. However, the device lacks a protective structure, which makes it easy for fragments to fly out during drill pipe strength testing. To address this issue, we propose a semi-automatic impact testing device for drill pipe strength testing. Summary of the Invention
