[0002] In open-pit mining, various engineering construction, underground deep hole mining, large industrial site leveling and other projects, deep hole blasting has an irreplaceable position and very high technical and economic effects in its application process. With the continuous updating and development of various large-scale mechanical equipment and blasting equipment, blasting technology has been highly improved.

[0003] However, in the current open-pit mine environment, the drilled blastholes usually need to be loaded and blasted after a period of time. Due to the limitations of the open-pit environment, the drilled holes may be damaged or even collapsed for various reasons, delaying the progress of the project. Therefore, the drilled holes need to be protected by hole protection devices. In addition, because the hole diameters are different, the placed hole protection devices are easily lost due to external factors such as wind or human factors, resulting in hole protection failure.

[0021] Example:

[0022] See also Figure 1-4 The utility model provides a technical solution: a drill-type open-pit mine hole protection device, including a sealing panel 1, which can seal the hole to prevent external influences from entering the hole. A connecting plate 2 is arranged around the upper side of the sealing panel 1, and a pressing ring 3 is fixedly connected to the upper side of the connecting plate 2. A connecting rod 4 is arranged on the upper side of the sealing panel 1, and a pressing plate 5 is fixedly connected to the upper side of the connecting rod 4. A pressing plate 6 is fixedly connected to the lower side of the pressing plate 5. The lower sides of the four connecting rods 4 are fixedly connected to a limiting plate 7. The lower side of the sealing panel 1 is provided with a fixed hole bottom Plate 8 supports and stabilizes the hole to prevent collapse. An installation groove 9 is opened on the upper side of the fixed hole bottom plate 8. Support seats 10 are fixedly connected to the bottom of the inner side of the installation groove 9. Compression springs 11 are symmetrically connected to the opposite sides of the four support seats 10. Support legs 12 are penetrated through the outer sides of the support seats 10 and the fixed hole bottom plate 8. The inner walls of different holes can be adjusted and supported, and the hole protection device can be prevented from being lifted by external force, so that the hole sealing is stable and the effect is better. Sliders 13 are fixedly connected to the opposite ends of the support legs 12 and the compression springs 11.

[0023] The pressing plate 5 is located on the inner side of the inner ring of the pressing ring 3, and screw holes 14 are arranged around the upper side of the sealing panel 1, and the screw holes 14 are located on the outer side of the outer ring of the pressing ring 3. Screws are nailed into the screw holes 14 to fix the sealing panel 1. The fixed hole bottom plate 8 is fixedly plugged into the sealing panel 1, and the supporting hole legs 12 are located on the upper side of the compression spring 11. A fixed plugging hole 15 is opened on the upper side of the slider 13, and the fixed plugging hole 15 corresponds to the limiting plate 7. The limiting plate 7 sinks and can be plugged into the inner side of the fixed plugging hole 15 to fix the slider 13. The outer side of the pressing plate 6 is set as a slope surface, and the opposite side of the slider 13 is set as a slope surface. Therefore, in the process of sinking the pressing plate 6, the four sliders 13 are pushed to move in four vertical directions. The slider 13 compresses the compression spring 11 and pushes the supporting hole legs 12 out of the fixed hole bottom plate 8. The outer side of the pressing plate 6 corresponds to the opposite side of the slider 13, and the side wall on the inner side of the mounting groove 9 is in contact with the opposite side of the support seat 10.

[0024] Working principle: When in use, place the sealing panel 1 on the upper side of the hole so that the fixed hole bottom plate 8 is inserted into the hole, and then screws are screwed into the screw holes 14 to fix the sealing panel 1. Then, press the pressing plate 5 to drive the pressing plate 6 to sink. The corresponding surfaces of the pressing plate 6 and the slider 13 are both sloped surfaces. Therefore, during the sinking process of the pressing plate 6, the four sliders 13 are pushed to move in four vertical directions. The slider 13 compresses the compression spring 11 and pushes the hole support leg 12 out of the fixed hole bottom plate 8. Then, press the pressing ring 3 so that The limit plate 7 sinks and is inserted into the inner side of the fixed plug-in hole 15, fixing the slider 13, so that the hole-supporting legs 12 support the inner wall of the hole to support and fix the device. When disassembling, it is only necessary to lift the pressing ring 3 to make the limit plate 7 rise and detach from the inner side of the fixed plug-in hole 15, then the compression spring 11 is reset and the pressure plate 6 is lifted, and the pressing plate 5 is lifted accordingly. At the same time, the hole-supporting legs 12 are retracted, and then the screws are removed to complete the disassembly. This design has a simple structure and is relatively convenient to install and disassemble.
