Description

Technical Field

[0001] The invention relates to the technical field of geological detection, and in particular to a drilling probe. Background Art

[0002] At present, blasting technology has been widely used in open-pit mines, railways, highways, quarries and other places. Under the complex working conditions of underground mines, holes are usually drilled downward to form blastholes, and then explosives are loaded in the re-drilled holes for blasting. The stability of the blastholes has become an important factor restricting the production blasting of underground mines, affecting the efficiency of drilling and hole inspection. Since the boreholes in the mines are vacant for a long time, when the boreholes are affected by many factors such as rock conditions and construction disturbances, the inner wall of the borehole will produce serious bulges, resulting in a decrease in the inner diameter of the borehole, which seriously affects the efficiency of mine blasting. Therefore, before charging and blasting the borehole, it is necessary to detect the internal conditions of the borehole to determine the internal conditions of the borehole. The existing borehole detection head only has the function of detecting the borehole, and is unable to repair the borehole with bulges and other blockages on the inner wall while detecting the borehole. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a drilling probe to solve the problem that the drilling detection head in the prior art only has the function of detecting the borehole, and cannot repair the borehole with blockage such as bulging inner wall while detecting the borehole.

[0004] To solve the above technical problems, a basic solution adopted by the present invention is a drilling probe, comprising a walking part, a detection part and a cutting part, the walking part comprising an upper base, a plurality of elastic plates evenly distributed along the outer wall of the upper base and a braking mechanism arranged on the upper base for controlling the movement state of the upper base, the upper end of the elastic plate is a free end, the lower end of the elastic plate is rotatably connected to the upper base, the upper base is provided with an elastic member 1 for forcing the upper end of the elastic plate to move away from the upper base, the cutting part comprises a slide plate arranged below the upper base, a driving member 1 fixedly connected to the upper base for driving the slide plate to slide up and down, a rotating cutting mechanism arranged below the slide plate and a driving member 2 fixedly connected to the slide plate for driving the rotating cutting mechanism to rotate, the detection part comprises a camera located below the rotating cutting mechanism, the braking mechanism, the driving member 1 and the driving member 2 are all electrically connected to a controller on the ground, and the camera is electrically connected to a monitor on the ground.

[0005] In the above scheme, a suspension rope is tied at the center of the upper surface of the upper base, the entire probe is placed vertically into the borehole, and the probe slides downward under its own weight. The speed of the probe sliding downward is controlled by the suspension rope, and the condition of the borehole wall in the borehole is observed through a monitor. When it is found that the borehole wall has a bulge phenomenon causing a blockage phenomenon that reduces the borehole diameter, the brake is controlled by operating the controller to brake the upper base to prevent the upper base from moving and rotating. Then, drive member 1 and drive member 2 are operated. When drive member 1 pushes the slide plate to move downward, drive member 2 drives the rotating cutting mechanism to rotate and cut off the bulging part on the inner wall of the borehole.

[0006] Furthermore, the upper base is a cylindrical body, and the driving member includes an electric cylinder with an output shaft arranged downward, the electric cylinder is fixedly connected to the bottom surface of the upper base, the bottom surface of the upper base is vertically fixedly connected to a sliding column, the slide plate is fixedly connected to the output shaft of the electric cylinder, and a sliding hole is provided on the slide plate for sliding cooperation with the sliding column.

When the camera finds that the inner wall of the borehole bulges toward the middle of the borehole, the lifting rope is stopped after the cutting wheel is close to the top of the bulging part. The brake mechanism is controlled by the controller to brake the upper base to prevent the upper base from rotating and moving. The driving member 2 is then controlled to drive the center column to drive the cutting rod to rotate synchronously. The cutting wheel at the lower end of the cutting rod rotates around the axis of the center column to cut the bulging part on the inner wall of the borehole.

[0011] When the rotating cover is rotated, the rotating cover drives the limit sleeve to slide up and down in cooperation with the upper thread of the center column to limit the opening angle of the cutting rod, so that the cutting rod can be used in drill holes of different sizes. When the driving member 2 drives the center column to rotate, the limit sleeve rotates synchronously and drives the cutting rod to rotate through the slot that cooperates with the cutting rod.

[0012] Furthermore, the braking mechanism includes a plurality of electric push rods arranged along the radial direction of the upper base and arranged corresponding to the elastic plates, the electric push rods are fixedly connected to the top surface of the upper base, and the output shaft ends of the electric push rods are set as pointed ends.
