Description

Technical Field

[0001] This application relates to a device for measuring the rock boundary of medium-deep boreholes in metal mines. Background Technology

[0002] Common hole-measuring tools are mainly divided into two categories: physical measuring tools and optical measuring tools. Their function is to detect parameters such as the center position, coaxiality, diameter, and length of the hole. However, they cannot measure the mineral waste between magnetite and waste rock, and their price is relatively high. Through on-site observation and practical operation, a simple, inexpensive, and easy-to-operate hole-measuring tool was developed. The original problem was that the operating rod for measuring the hole was of uneven thickness, making it prone to jamming; the operating rod was also generally heavy, making operation inconvenient. Utility Model Content

[0003] To address the aforementioned problems, this application provides an apparatus for measuring the ore-rock boundary in medium-deep boreholes in metal mines.

[0004] The dust suppression device for underground power distribution chambers provided in this application adopts the following technical solution: A device for measuring the ore-rock boundary in a medium-deep borehole in a metal mine includes a borehole measuring main rod, a magnetic head, a fixed connection assembly, and an extension rod. The borehole measuring main rod consists of an insertion section and a detection section, wherein the insertion section is connected to the fixed connection assembly located at one end of the extension rod, and the magnetic head is fixedly mounted at the top of the lower detection section. The fixed connection assembly includes a stainless steel sheet, a spring, and a stainless steel pin. The stainless steel sheet is fixedly installed at one end of the extension rod. One end of the spring is fixedly connected to the stainless steel sheet, and the other end abuts against the stainless steel pin. The stainless steel pin can extend partially under the elastic force of the spring and engage with the corresponding locking pin opening on the wall of the through section.

[0005] This utility model further defines the technical solution as follows: Preferably, the magnetic suction head is assembled to the top of the detection section by a spring-loaded fixing structure. The spring-loaded fixing structure includes an M8 threaded component and a spring-loaded clip. The top tube of the detection section is provided with an internal thread. The M8 threaded component is threadedly connected to the internal thread at the top of the detection section. The spring-loaded clip is fixed to the front end of the M8 threaded component. The magnetic suction head is clamped and fixed to the top of the detection section by the spring-loaded clip.

[0006] Preferably, the measuring hole body rod is a one-piece structure made of carbon fiber, with a diameter of Φ18mm, a total length of 1200mm, and its outer surface is smoothed.

[0007] Preferably, the diameter of the extension rod is the same as that of the main rod of the measuring hole, both being Φ18mm. It is made of carbon fiber, has a length of 1200mm, and its outer surface is smoothed.

[0008] Preferably, the adsorption end face of the magnetic suction head has an arc-shaped structure, and the radius of the arc is consistent with the radius of the measuring hole body rod.

[0009] Preferably, the other end of the extension rod is provided with a pin hole of the same size as the locking pin opening, and the extension rod is detachably and fixedly connected to multiple extension rods by engaging with a stainless steel pin through the pin hole.

[0010] In summary, this application includes the following beneficial technical effects: This utility model's main measuring rod and extension rod are both integrally formed from carbon fiber tubes with a diameter of Φ18mm, and the outer surface is smoothed. It eliminates the structural defects of traditional operating rods with uneven thickness, completely avoiding hole jamming caused by inconsistent rod dimensions during measurement. This ensures smooth operation when probing up and down in medium and deep holes, reducing the risk of on-site operation interruption. Furthermore, the use of lightweight carbon fiber material significantly reduces the overall weight while meeting the strength requirements of the rod, allowing for installation, disassembly, carrying, and probing operations to be completed by a single person. It is especially suitable for narrow working spaces in mines, improving operational efficiency and user experience.

[0011] This invention allows for the flexible addition of an extension rod via a fixed connection assembly for the interlocking section. The length of the extension rod can be adjusted to suit the actual hole depth, eliminating the need for custom-made tools for different hole depths and reducing tool compatibility costs.
