Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to a hole expansion protection device for mining geological exploration. Background Art

[0002] An important aspect of geological exploration is the collection of soil and rock samples, which are crucial for analyzing stratigraphic structure, determining mineral composition, and assessing the potential of mineral resources. To obtain these samples, drilling is usually performed using an expander to create holes for testing.

[0003] Chinese Patent 202420233398.2 discloses a hole-expanding protective device for mining geological exploration, comprising a control box, a mounting plate connected to one side of the control box, storage boxes mounted on both sides of the control box, an opening formed below the control box, a support frame connected to the bottom of the control box, a slide bar connected to the interior of the control box, a support plate connected to the top of the interior of the control box, a first rotating rod passing through the center of the support plate, a first bevel gear connected to the first rotating rod, and a second bevel gear meshingly connected to the first bevel gear. By providing a support frame, a protective plate, a clamping block, and a clamping slot, the expanded protective plate is mounted on the support frame by clamping the clamping block into the clamping slot. Splashing debris generated by a high-speed drill drilling into the ground will impact the protective plate, thereby preventing the debris from flying around and protecting surrounding workers from injury. The clamping connection between the clamping block and the clamping slot allows workers to quickly install the protective plate and provide timely protection.

[0004] In order to prevent gravel from flying around, the above-mentioned hole expansion protection device requires the staff to manually insert the card block into the preset card slot before each hole expansion operation to ensure that the protection plate can be firmly unfolded and installed on the support frame. This installation process is relatively troublesome, which increases the operation time, reduces work efficiency, and has a limited protection range. Therefore, a hole expansion protection device for mine geological exploration is proposed. Utility Model Content

For those skilled in the art, the specific meanings of the above terms in this utility model can be understood by those skilled in the art in specific circumstances.

[0027] like Figure 1-5 As shown, the utility model proposes a hole expansion protection device for mine geological exploration, including a mounting shell 2, an opening 21 passing through the middle of the lower end of the mounting shell 2, a lifting mechanism is provided inside the mounting shell 2, and a driving assembly is provided on the lifting end of the lifting mechanism, and the driving assembly is coaxially connected to the opening 21 through a transmission rod 19, and support ring plates 5 are provided on both sides of the bottom of the mounting shell 2. The support ring plates 5 on both sides are point symmetrical, and a second slot 10 is provided inside the support ring plate 5. Sliding assemblies are provided on the upper and lower sides of the inner end surface of the second slot 10, and an annular partition 6 is provided between the moving ends of the upper and lower sliding assemblies, and a first slot 8 is provided on the outer end surface of the support ring plate 5, and a handle 9 is provided on the outer end surface of the first slot 8 and located inside the first slot 8.

[0028] In the utility model, when expanding a hole for geological exploration of a mine, the staff pulls the handle 9 to make the annular partition 6 slide in an annular manner inside the second slot 10 through the sliding components on both sides, so that the annular partition 6 contacts the side of the support ring plate 5 on the other side. At this time, protection can be provided during hole expansion, and then the lifting mechanism can be used to drive the driving component to descend, and the driving component can drive the drill bit 20 to rotate through the transmission rod 19, so that hole expansion can be carried out during geological exploration of a mine; and when there is no need to expand a hole, the lifting mechanism can drive the drill bit 20 to be located inside the mounting shell 2, thereby preventing the drill bit 20 from contacting external staff and preventing damage.

[0029] In an optional embodiment, the sliding assembly includes a slider 11 and a slide rail 12, the upper and lower sides of the inner end surface of the second slot 10 are connected to the slide rail 12, and the upper and lower sides of the annular partition 6 are slidingly connected to the slide grooves of the slide rails 12 on both sides through the slider 11.

[0030] It should be noted that when the annular partition 6 moves, the sliders 11 on the upper and lower sides of the annular partition 6 move in the slide grooves of the upper and lower slide rails 12, ensuring the stability of the annular partition 6 during annular sliding.

[0031] In an optional embodiment, the first magnetic plate 4 is embedded in the side of the supporting ring plate 5 , and the second magnetic plate 7 is embedded in the side of the annular partition plate 6 .

[0032] It should be noted that the second magnetic plate 7 on one side of the annular partition 6 is connected to the first magnetic plate 4 on the other side of the supporting ring plate 5 by magnetic force, thereby preventing the annular partition 6 from moving due to vibration generated during drilling.

[0033] In an optional embodiment, the lifting mechanism includes a first motor 1, a threaded sleeve 13, a threaded rod 14, a lifting plate 18 and a stabilizing component. The first motor 1 is arranged at the edge of the upper end of the mounting shell 2, and one end of the threaded rod 14 is rotatably connected to the inner bottom wall of the mounting shell 2. The other side of the threaded rod 14 passes through the upper end of the mounting shell 2 and is coaxially connected to the output end of the first motor 1 through a coupling. The threaded sleeve 13 is threadedly sleeved on the outer end surface of the threaded rod 14, the lifting plate 18, and multiple stabilizing components are spaced apart between the upper and lower inner walls of the mounting shell 2. The threaded sleeve 13 and the moving ends of the multiple stabilizing components pass through the lifting plate 18, and the driving component is arranged in the middle of the upper end surface of the lifting plate 18.

[0034] It should be noted that when the first motor 1 is started, the first motor 1 can drive the threaded rod 14 to rotate, and the threaded rod 14 can drive the threaded sleeve 13 to rise and fall when rotating. The threaded sleeve 13 can pass through multiple stabilizing components when rising and falling, thereby driving the lifting plate 18 to rise and fall stably, and the lifting plate 18 can drive the driving component to rise and fall when rising and falling.

[0035] In an optional embodiment, the stabilizing assembly includes a sliding rod 16 and a sliding sleeve 17. The sliding rod 16 is arranged between the upper and lower inner walls of the mounting shell 2. The sliding sleeve 17 is slidably sleeved on the outer end surface of the sliding rod 16. The sliding sleeve 17 vertically passes through the lifting plate 18, wherein the threaded rod 14 and the multiple sliding rods 16 are arranged in parallel.

[0036] It should be noted that when the lifting plate 18 is being lifted or lowered, the sliding sleeve 17 can be driven to slide up and down on the sliding rod 16 , thereby ensuring the stability of the lifting plate 18 during the lifting or lowering.

[0037] In an optional embodiment, the drive assembly includes a second motor 15, the upper end of a transmission rod 19 passes through the lifting plate 18 and is coaxially connected to the output end of the second motor 15, and the lower end of the transmission rod 19 is connected to a drill bit 20. The drill bit 20 and the opening 21 are located at the same center, and the radius of the drill bit 20 is smaller than the inner diameter of the opening 21.
