Description

Technical Field

[0001] This utility model relates to the field of mining engineering technology, specifically to a depth measuring device for mining engineering. Background Technology

[0002] Mining is the technology and science of extracting mineral resources from the Earth's crust or surface. Mining generally refers to the extraction of metallic or non-metallic mineral deposits; in a broader sense, it also includes the extraction and beneficiation of coal and oil. Essentially, it is a selective collection and transportation process of materials. Currently, in mining engineering practice, it is often necessary to drill blast holes and then load appropriate amounts of explosives for blasting. The depth of these blast holes must frequently be measured. The depth measurement device typically involves fixing a weight to the end of a measuring rope, inserting it vertically into the bottom of the blast hole, and reading the depth upon contact with the bottom.

[0003] Existing depth measuring devices typically use screws and nuts for connection. When disassembling or repairing the equipment, tools such as screwdrivers or wrenches are required, which is inconvenient. Furthermore, when measuring the depth of blast holes, the height difference between the device base and the ground causes errors in the measured depth of the measuring rope. Therefore, a depth measuring device for mining engineering is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a depth measuring device for mining engineering to solve the problems mentioned in the background art.

[0005] By adopting the above technical solution, the hole measuring instrument and the base can be quickly installed and disassembled.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] 1. In this utility model, the hole measuring instrument is connected and fixed to the base by the latch in the latch assembly on the hole measuring instrument. The latch is retracted by pulling up the lever, and the lever is moved out by the third lever to lock the second stop, thereby separating the hole measuring instrument from the base and realizing the quick disassembly function of the hole measuring instrument from the base.

[0008] 2. In this utility model, by retracting the first stop block by the first detonator, the measuring scale extends to measure the distance between the base and the ground. Then, by retracting the measuring scale by the second detonator and moving the first stop block out, the measuring scale is limited and fixed, thereby solving the measurement error problem caused by the distance between the base and the ground.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 This utility model provides a technical solution: a depth measuring device for mining engineering, including a borehole measuring instrument 1 and a base 5. The borehole measuring instrument 1 is equipped with a measuring component, and the base 5 has a rope hole 23. The depth of the blast hole is measured by the measuring component. The borehole measuring instrument 1 is existing technology and will not be described in detail here. Multiple buckle components are installed on the outside of the borehole measuring instrument 1, and multiple buckle holes 22 are opened on the base 5. The borehole measuring instrument 1 is connected and fixed to the base 5 by the buckle components on the borehole measuring instrument 1 locking the buckle holes 22 on the base 5, so as to realize the quick installation and disassembly of the borehole measuring instrument 1 and the base 5.

[0017] The latching assembly includes a retainer 11, which is fixedly connected to the outside of the hole measuring instrument 1. A latch 17 is slidably connected inside the retainer 11. Two springs 21 are fixedly connected to the outside of the latch 17. A lever 16 is fixedly connected to the top of the latch 17. The springs 21 allow the latch 17 to lock into the latch hole 22 on the base 5. The latch 17 is retracted by pulling up the lever 16. A sliding groove 3 18 is fixedly connected to the top of the retainer 11. A stop 20 is slidably connected inside the sliding groove 3 18. A lever 3 19 is fixedly connected to the left end of the stop 20. After the latch 17 is retracted, the lever 3 19 is moved to the right to extend the stop 20, thereby locking the lever 16 and fixing the latch 17.

[0018] Please see Figure 1 and Figure 5 The outer side of the hole measuring instrument 1 is fixedly connected to a slide groove 3, and the inner side of the slide groove 3 is slidably connected to a measuring scale 4. The upper end of the measuring scale 4 is fixedly connected to a pivot pin 2. A limit component is installed on the outer side of the hole measuring instrument 1. The measuring scale 4 is pushed out by moving the pivot pin 2, thereby measuring the height between the base 5 and the ground. The measuring scale 4 is limited by the limit component.

[0019] Please see Figure 1 , Figure 4 and Figure 5 The limiting component includes a second slide groove 8, with a stop block 6 slidably connected inside the slide groove 8. A lever 7 is fixedly connected to the right end of the stop block 6. The lever 7 moves the stop block 6 to limit the measuring scale 4. Multiple telescopic legs 12 are rotatably connected to the bottom of the base 5. The measuring component includes a measuring rope 10, which is located inside the rope hole 23. A measuring hammer 9 is fixedly connected to the bottom of the measuring rope 10. Multiple control buttons 13 are installed on the outside of the borehole measuring instrument 1. A display screen 14 is installed on the outside of the borehole measuring instrument 1. A handle 15 is rotatably connected to the outside of the borehole measuring instrument 1. The measuring rope 10 is retracted and extended by the measuring hammer 9 and the control buttons 13. The measuring hammer 9 reaches the bottom of the borehole to measure the depth. The display screen 14 is existing technology and displays depth information, which will not be described in detail here.

[0020] Working principle: Place the measuring hammer 9 in the blast hole, and control the expansion and contraction of the measuring rope 10 by the control button 13 so that the measuring hammer 9 reaches the bottom of the blast hole to measure the depth. The hole measuring instrument 1 is connected and fixed to the base 5 by locking the buckle component on the base 5 through the buckle hole 22. After pulling up the lever 16, the lever 16 is locked by the second stop 20, which can release the buckle component and realize the quick disassembly function of the hole measuring instrument 1 and the base 5.

[0021] By retracting the stop block 6 using the first lever 7, the measuring scale 4 is extended to measure the distance between the base 5 and the ground. The measuring scale 4 is then retracted using the second lever 2, and the stop block 6 is moved out to limit and fix the measuring scale 4, thereby solving the measurement error problem caused by the distance between the base 5 and the ground.
