Description

Technical Field

[0001] This utility model relates to the field of depth measuring instrument technology, specifically a mine borehole depth measuring instrument. Background Technology

[0002] Mining borehole drilling refers to drilling operations in underground mines. When drilling reaches a certain stage, it is necessary to measure the internal depth of the borehole. Depth is typically measured using a depth measuring instrument. Existing depth measuring instruments are devices used for measuring the depth of mining boreholes. The instrument is directly fixed to the top of the borehole, and the measuring rope is opened by rotating the winding shaft to the interior of the borehole for measurement, allowing for convenient and rapid measurement.

[0003] Chinese patent application number 202320265983.6 discloses a drilling depth measuring instrument for mines, including a measuring component movably mounted on a track. The measuring component also includes a support, with a fixed ring movably mounted at the top of the support; a connecting ring positioned above the fixed ring; and a track mounted on the connecting ring. Further, the measuring component includes a rotating seat positioned below the track, with a rotating shaft rotatably mounted on the rotating seat. A drum is mounted on the rotating shaft, and a measuring rope is wound on the drum. The measuring rope has graduations, one end of which is connected to the drum, and the other end has a plumb bob. A pressure sensor is mounted at the bottom of the plumb bob. The measuring component is movably mounted on the track, and its installation is achieved by engaging a crossbar with the track. The structure is simple and easy to use, allowing for convenient measurement at different locations. The pressure sensor on the plumb bob allows for easy detection of whether the plumb bob has reached the bottom, avoiding reliance on experience and ensuring accurate data.

[0004] When this mine borehole depth measuring instrument measures borehole depth, the measuring rope comes into contact with the borehole wall during its extension, causing it to accumulate a significant amount of dirt and other debris. When winding up the measuring rope, it is necessary to promptly clean the dirt and other debris adhering to the outside of the rope; otherwise, the accumulated debris will be difficult to clean, leading to blurred graduations on the outer side of the rope and making data reading difficult. Furthermore, it will increase corrosion of the measuring rope, reducing its service life. Therefore, we propose a mine borehole depth measuring instrument. Utility Model Content
