Drilling peeping instrument capable of achieving single-person operation

Abstract

The invention relates to a drilling peeping instrument capable of achieving single-person operation, and belongs to the technical field of drilling peeping devices. The drilling peeping instrument solves the problems that an existing drilling peeping instrument is complicated in operation, the drilling peeping process is difficult to complete by a single person, the drilling depth recording accuracy is low, and the image quality is poor. The drilling peeping instrument includes a camera probe, a push rod, an imaging host and a metal frame. The camera probe is arranged at the end of the push rod, the metal frame is provided with a depth counter pulley, and the camera probe and the depth counter pulley are connected to the imaging host through cables. The outer circumference of the depth counter pulley is uniformly provided with protrusions, and the push rod is provided with push rod grooves matched with the protrusions; the depth counter pulley is provided with a rotating rod, and the depth counter pulley is controlled by the rotating rod to rotate, the protrusions and the push rod grooves are matched to push the push rod to move the camera probe into a drilled hole, and the arc length rotation of the depth counter pulley is the moving distance of the camera probe. The drilling peeping instrument realizes single-person operation of the drilling peeping process, and the drillingdepth recording accuracy is high.

Description

technical field [0001] The invention relates to the technical field of borehole peeping devices, in particular to a borehole peeping instrument that can be operated by a single person. Background technique [0002] The borehole peeping instrument is an optical imaging device that can directly observe the internal conditions of the rock mass. It can store imaging videos and imaging expansion diagrams, so as to reproduce the internal structure of the borehole and facilitate later analysis. Therefore, the borehole peeping instrument is very useful for detecting coal seam structure. , geological structure, roadway surrounding rock control effect, etc. play a very important role. [0003] At present, the commonly used borehole peeping instrument is to connect the camera probe and the depth counter to the imaging host through a cable. The cable on the probe is installed on the pulley of the depth counter. In this way, the depth of the imaging part can be obtained, but the operati...
