Description

Technical Field

[0001] This utility model relates to the field of mine blasting technology, and in particular to a drilling equipment for mine blasting. Background Technology

[0002] When mining ore, some rock strata are too hard for machinery to excavate. Blasting is usually required. During blasting, holes need to be drilled in the harder rock strata, and explosives are placed into the holes. When the explosives explode in the soil and rock medium, the soil and rock medium is compressed, deformed, broken, loosened and thrown, thus achieving the effect of blasting.

[0003] In existing technologies, ore mining employs a bottom-up mining method. Several blast holes are drilled in the top surface of the next level of the mine, explosives are filled into these holes, and mining operations are carried out through blasting, connecting the upper and lower levels of the mine. However, when drilling, the existing drilling equipment is inconvenient to adjust due to the slight difference in the height of the mine ceiling, which causes practical problems. At the same time, drilling easily causes dust and stone chips to fly around, which can easily cause environmental pollution due to flying dust and safety hazards due to flying stone chips. Therefore, there is room for improvement. Utility Model Content

[0004] This utility model provides a drilling equipment for blasting in mines to solve the problems mentioned in the background art.

[0005] To address the aforementioned problems, this utility model provides a drilling device for mine blasting, comprising a movable base, a movable mechanism, and a drilling mechanism. The movable base has two symmetrically arranged fixed plates, with a first threaded rod rotatably mounted between the two fixed plates. One end of the first threaded rod rotatably passes through one of the fixed plates and is connected to a first motor mounted on the movable base. The movable mechanism is mounted on the movable base and consists of a movable plate, a lifting frame, and a second motor. A drive block threadedly connected to the first threaded rod is located in the center of the bottom surface of the movable plate. Two symmetrically arranged support columns are fixed on one side of the upper part of the movable plate, and a first U-shaped frame is fixed in the center of the movable plate. A second threaded rod, passing through the first U-shaped frame, is rotatably mounted vertically upwards in the movable plate. The second threaded rod is located at the bottom of the first U-shaped frame and a first bevel gear is installed thereon. The first bevel gear meshes with the second bevel gear, and the second bevel gear is connected to the second motor mounted on the movable plate. The lifting frame is provided with limit sliders at both ends, and the limit sliders are slidably connected to the support column. A second U-shaped frame that is threadedly connected to the second threaded rod is fixedly installed on the outer side of the lifting frame. The drilling mechanism is installed on the lifting frame and consists of a hydraulic telescopic rod, a third motor, a drill rod, and a corrugated cover. The hydraulic telescopic rod is installed in the lifting frame and the telescopic end is connected to the mounting frame. The third motor is installed in the mounting frame and the power output end is connected to the drill rod. The corrugated cover is installed on the top of the mounting frame and covers the drill rod inside.

[0006] Preferably, two positioning plates are symmetrically installed on both sides of the movable base, and positioning rods are threadedly connected to the positioning plates.

[0007] Preferably, two sets of first guide rods are symmetrically arranged between the two fixed plates on the movable base, located on both sides of the first threaded rod, and each set of first guide rods consists of two rods. The bottom of the movable plate is symmetrically provided with first sliders that are slidably connected to the two sets of guide rods.

[0008] Preferably, an L-shaped limiting frame is installed on the top of the support column, and a second guide rod is slidably connected in the L-shaped limiting frame. The bottom end of the second guide rod is fixedly installed on the upper part of the lifting frame, and second sliders that are slidably connected to the second guide rod are symmetrically fixed on both sides of the mounting frame.

[0009] Preferably, the support column is provided with a plurality of first positioning grooves at equal intervals, the limiting slider is provided with a second positioning groove that matches the first positioning grooves, and a limiting block is inserted into the second positioning groove and the first positioning groove.

[0010] The beneficial effects of adopting the above technical solutions are:

[0011] 1. The movable base facilitates the movement of the entire device, and the positioning rod in the positioning plate facilitates the positioning of the movable base, thereby ensuring stability during operation.

[0012] 2. The corrugated cover can protect against dust and stone chips generated when the third motor drives the drill rod to drill, thereby avoiding environmental pollution and safety hazards caused by flying stone chips.

[0013] 3. The first motor drives the rotation of the first threaded rod, which allows the movable plate to move, thus facilitating the lateral movement of the drilling mechanism. This enables multiple boreholes to be drilled in the same row without moving the equipment, thereby improving work efficiency.

[0014] 4. The second motor drives the second bevel gear to drive the first bevel gear, which in turn rotates the second threaded rod. This, in turn, drives the lifting frame to move up and down between the two support columns via the threaded second U-shaped frame, thereby completing the height adjustment of the drilling mechanism. This facilitates drilling blast holes at different heights in the mine top layer and improves the convenience of the work. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1-4In this embodiment, a drilling device for blasting in a mine includes a movable base 1, a movable mechanism 2, and a drilling mechanism 3. The movable base 1 has two fixed plates 11 symmetrically arranged, and a first threaded rod 12 is rotatably arranged between the two fixed plates 11. One end of the first threaded rod 12 rotatably passes through a fixed plate 11 and is connected to a first motor 13 installed on the movable base 1. The movable mechanism 2 is arranged on the movable base 1 and is composed of a movable plate 21, a lifting frame 22, and a second motor 23. A driving block 211 threadedly connected to the first threaded rod 12 is provided in the middle of the bottom surface of the movable plate 21. Two support columns 24 are symmetrically fixed on one side of the upper part of the movable plate 21, and a first U-shaped frame 25 is fixed in the middle of the upper part of the movable plate 21. A second threaded rod 26 is rotatably arranged vertically upward in the movable plate 21, passing through the first U-shaped frame 25, and the second threaded rod 26 is located at the first... A first bevel gear 261 is installed at the bottom of the U-shaped frame 25. The first bevel gear 261 meshes with a second bevel gear 231, and the second bevel gear 231 is connected to a second motor 23 installed on the movable plate 21. The lifting frame 22 has limit sliders 221 at both ends, and the limit sliders 221 are slidably connected to the support column 24. A second U-shaped frame 27, which is threadedly connected to the second threaded rod 26, is fixedly installed on the outer side of the lifting frame 22. The drilling mechanism 3 is installed on the lifting frame 22 and consists of a hydraulic telescopic rod 31, a third motor 32, a drill rod 33, and a corrugated cover 34. The hydraulic telescopic rod 31 is installed in the lifting frame 22, and the telescopic end is connected to the mounting frame 35. The third motor 32 is installed in the mounting frame 35, and the power output end is connected to the drill rod 33. The corrugated cover 34 is installed on the top of the mounting frame 35 and covers the drill rod 33 inside.

[0024] With the above technical solution, the equipment is moved to the location where blasting holes need to be drilled via the movable base 1. The second motor 23 in the movable mechanism 2 drives the second bevel gear 231 to rotate, which in turn drives the second threaded rod 26 to rotate in the first U-shaped frame 25 through the meshing first bevel gear 261. The first U-shaped frame 25 ensures the stability of the rotation of the second threaded rod 26. The rotation of the second threaded rod 26, in conjunction with the threaded connection of the second U-shaped frame 27, drives the lifting frame 22 to adjust its height between the two support columns 24, thereby adjusting the height of the drilling mechanism 3 installed on the lifting frame 22. This facilitates blasting work on the mine top at different heights, improving work convenience. The drill rod 33 is driven by the third motor 32. The rotation, combined with the movement of the hydraulic telescopic rod pushing the mounting bracket 35, causes the third motor 32 to push upwards to complete the drilling work. During the drilling work, the corrugated cover 34 covers the drill hole 33, and the dust and stone chips generated will fall into the corrugated cover 34, avoiding environmental pollution caused by dust and safety hazards caused by flying stone chips. Due to the foldable nature of the corrugated cover 34, the dustproof and flying stone prevention effect can be guaranteed without hindering the drilling work. The rotation of the first threaded rod 12 driven by the first motor 13 can drive the movable plate 21 to move on the movable base 1, thereby adjusting the position of the drilling mechanism 3, which is convenient for drilling different positions on the top of the mine. It is not necessary to change the position of the equipment for each hole, thus improving work efficiency.

[0025] Preferably, two positioning plates 4 are symmetrically installed on both sides of the movable base 1, and positioning rods 41 are threadedly connected to the positioning plates 4.

[0026] Through the above technical solution, the positioning rod 41 is inserted into the ground and cooperates with the positioning plate 4 to make the moving base 1 stably placed on the ground, thereby improving the stability of drilling.

[0027] Preferably, two sets of first guide rods 14 are symmetrically arranged between the two fixed plates 11 on the movable base 1 on both sides of the first threaded rod 12, and each set of first guide rods 14 consists of two rods. The bottom of the movable plate 21 is symmetrically provided with first sliders 212 that are slidably connected to the two sets of guide rods 14.

[0028] Through the above technical solution, the two sets of first guide rods 14, together with the first slider 212, make the sliding connection of the movable plate 21 on the movable base 1 more stable.

[0029] Preferably, an L-shaped limiting frame 5 is installed on the top of the support column 24, and a second guide rod 51 is slidably connected in the L-shaped limiting frame 5. The bottom end of the second guide rod 51 is fixedly installed on the upper part of the lifting frame 22. The two sides of the mounting frame 35 are symmetrically fixed with second sliders 351 that are slidably connected to the second guide rod 51.

[0030] Through the above technical solution, the L-shaped limiting frame 35 can prevent the lifting frame 22 from detaching from the support column 24. By cooperating with the second guide rod 51, the stability of the lifting frame 22 when moving is further improved, while ensuring the stability of the hydraulic telescopic rod 31 driving the mounting frame 35 to move, thereby ensuring the stability of drilling.

[0031] Preferably, the support column 24 is provided with a plurality of first positioning grooves 241 at equal intervals, and the limiting slider 221 is provided with a second positioning groove 222 matching the first positioning grooves 241, and a limiting block is inserted into the second positioning groove 222 and the first positioning groove 241.

[0032] With the above technical solution, after the lifting frame 22 is adjusted to the position in the support column 24, the second positioning groove 222 corresponds to the first positioning groove 241. At this time, the limiting block is inserted into the second positioning groove 222 and the first positioning groove 241, so that the lifting frame 22 is stably connected to the support column 24, thereby ensuring the stability of the drilling mechanism 3 after the height is adjusted.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit the technical solutions described in this utility model. Therefore, although this specification has described this utility model in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model, and all technical solutions and improvements that do not depart from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model; technologies not described in detail in this utility model are implemented using existing technologies.
