Description

Technical Field

[0001] This invention relates to the field of mine drilling rescue technology, specifically a large-diameter rescue borehole directional drilling device. Background Technology

[0002] With the development of mining engineering, shallow resources are becoming increasingly scarce, leading to a gradual increase in the depth and scale of mining. Due to the complex environment of underground mining, despite the existence of standardized safety measures, mining accidents still occur, causing huge economic losses and trapping miners inside the mine, requiring rescue operations.

[0003] Currently, large-diameter drilling rescue is widely used as an efficient and rapid rescue method. It can quickly build a rescue channel between the ground and the trapped area to achieve the goal of rapid rescue. However, during drilling, the drilling direction often deviates, which requires repeated drilling operations. When encountering underground structures, the path needs to be replanned, and the drilling angle cannot be quickly adjusted, which prevents the trapped personnel from being rescued quickly and wastes a lot of rescue time.

[0004] Therefore, it is necessary to provide a large-diameter rescue borehole directional drilling device to solve the problems mentioned in the background art. Summary of the Invention

[0026] Example: Please refer to Figures 1-4 In this embodiment of the invention, a large-diameter rescue drilling directional drilling device includes a base 1, a fixing ring 2, a drill rod 3, a drill bit 5, and an adjustment mechanism 4. The fixing ring 2 is fixedly mounted on the base 1, and a through hole 11 is provided on the base 1. The adjustment mechanism 4 is disposed inside the fixing ring 2. The drill rod 3 passes through the adjustment mechanism 4 and is driven by a driving mechanism. The output end of the drill rod 3 is provided with a drill bit 5, and the diameter of the through hole 11 is larger than the diameter of the drill bit 5.

[0027] During implementation, the drill rod 3 is passed through the adjustment mechanism 4 and then connected to the drill bit 5. The drilling direction of the drill rod 3 is fixed by the adjustment mechanism 4. Then, the drill rod 3 and the drill bit 5 are driven by the drive mechanism 5 to drill a large-diameter hole to build a rescue channel. During the drilling process, the drill cuttings are discharged into the cuttings discharge chamber 12, and under the action of the cuttings discharge mechanism 6, the cuttings are discharged to the outside of the fixing ring 2 to prevent the cuttings from affecting the adjustment mechanism 4.

[0028] In this embodiment, as Figure 1 , 3 The adjusting mechanism 4 includes a rotating ring 41, an adjusting ring 42, and adjusting rods 43. The rotating ring 41 is rotatably mounted on the fixed ring 2. Two adjusting rods 43 are symmetrically rotatably mounted on the inner side of the rotating ring 41. The other ends of the two adjusting rods 43 are fixedly mounted on the adjusting ring 42. The adjusting ring 42 is symmetrically hinged with two hydraulic rods 44 in the vertical direction of the adjusting rods 43. The other ends of the hydraulic rods 44 are hinged to the rotating ring 41.

[0029] During implementation, based on the location information of the trapped area, the position of the adjusting ring 41 is adjusted 360° in all directions by rotating the rotating ring 41 and the adjusting rod 43, thereby adjusting the direction of the drill rod 3. Subsequently, after the position of the adjusting ring 41 is fixed, hydraulic pressure is injected into the hydraulic rod 44 to completely fix the position of the adjusting ring 41, preventing it from deflecting during the drilling process and causing the drilling hole to deviate.

[0030] In addition, when encountering underground structures, the hydraulic rod 44 can be depressurized, and the rotating ring 41 and adjusting rod 43 can be rotated to quickly adjust the drilling angle of the drill rod 3, further shortening the rescue time and improving the rescue rate.

[0031] In this embodiment, as Figure 3 A motor 411 for driving the adjusting rod 43 is fixedly mounted on the rotating ring 41.

[0032] A second motor 21 is provided on the fixed ring 2;

[0033] A toothed ring is embedded on the outer side of the rotating ring 41, and the motor 21 drives the rotating ring 41 to rotate through gears.

[0034] In this embodiment, as Figure 4The upper side of the adjusting ring 42 is also provided with a plurality of guide mechanisms 45, including a guide plate 1 451, a guide plate 2 452 and a guide plate 3 453. The guide plate 1 451 is fixedly disposed on the adjusting ring 42. The guide plate 1 451 has a sliding groove 1 inside. The guide plate 2 452 is slidably disposed in the sliding groove 1. The guide plate 2 452 has a sliding groove 2 inside. The guide plate 3 453 is slidably disposed in the sliding groove 2.

[0035] Furthermore, a guide ring 454 is fixedly provided at the top of the guide plate 453.

[0036] In addition, there are various ways to drive the second guide plate 452 to slide along the first slide groove and the third guide plate 453 to slide along the second slide groove. They can be driven by hydraulic cylinders, lead screw and nut pair mechanisms and rack and pinion mechanisms.

[0037] Specifically, the guide mechanism 45 can further support and restrict the drill rod 3. The guide plate 2 452 and guide plate 3 453 slide out, so that the area of ​​the adjustment mechanism 4 acting on the drill rod 3 is further increased, thereby improving its support and restriction force. In addition, a guide ring 454 is provided at the top of the guide plate 3 453 to further increase the support strength of the support assembly 45.

[0038] In this embodiment, as Figure 4 The guide plate 1 451, guide plate 2 452 and guide plate 3 453 are all arc-shaped plates with the same diameter as the drill rod 3;

[0039] The inner diameter of the guide ring 454 is the same as the diameter of the drill rod 3.

[0040] It should be noted that, due to the large drilling depth, the larger the gap between the drill rod 3 and the adjustment mechanism 4, the greater the offset error. The guide plate 1 451, guide plate 2 452 and guide plate 3 453 are set as arc-shaped surfaces with the same diameter as the drill rod 3 so that they can fit tightly against the drill rod 3, thereby further reducing the influence of this error on the drilling direction.

[0041] In this embodiment, as Figure 2 , 3 The base 1 is also provided with a slag discharge chamber 12, and a slag discharge mechanism 6 is provided inside the slag discharge chamber 12.

[0042] A rubber pad 13 is also provided between the perforation 11 and the adjusting ring 42.

[0043] Specifically, the rubber pad 13 and the slag discharge chamber 12 are provided so that the drill cuttings are transferred in the slag discharge chamber 12 and isolated from the adjustment mechanism 4 by the action of the rubber pad 13, so as to prevent the drill cuttings from affecting the adjustment mechanism 4. Then, the drill cuttings are discharged to the outside of the fixing ring 2 by the slag discharge mechanism 6 to prevent the drill cuttings from clogging the borehole.

[0044] In this embodiment, as Figure 2 , 3 The slag discharge mechanism 6 includes a drive ring 61 and blades 62, wherein the drive ring 61 is rotatably disposed at the top of the slag discharge chamber 12, and a plurality of blades 62 are obliquely disposed at the bottom of the drive ring 61.

[0045] The base 1 is embedded with a motor 3, which can drive the drive ring 61 to rotate.

[0046] In this embodiment, as Figure 1 , 3 The base 1 is also provided with a plurality of slag discharge channels 14 at an angle, which are connected to the slag discharge chamber 12, and the output end of the slag discharge channel 14 is located outside the fixed ring 2.

[0047] During implementation, the drive ring 61 is driven counterclockwise by the motor 3. The drill cuttings are discharged to the outside of the slag discharge chamber 12 under the action of the blade 62, and discharged to the outside of the fixed ring 2 through the slag discharge channel 14. This effectively prevents the drill cuttings from clogging the borehole and isolates the drill cuttings from the adjustment mechanism 4, effectively avoiding the drill cuttings from affecting the adjustment mechanism 4 and causing the borehole to deviate.

[0048] In summary, when implementing this invention, the drill bit 5 is placed at the bottom of the fixing ring 2, and then the base is fixed above the trapped area. The drill rod 3 is passed through the adjusting ring 42 and connected to the drill bit 5. The rotating ring 41 and the adjusting rod 43 are rotated to adjust the deflection direction of the adjusting ring 42, thereby adjusting the drilling direction of the drill rod 3. After the adjustment is completed, the position of the adjusting ring 42 is fixed by the hydraulic rod 44. Then, the drilling position of the drill rod 3 is further fixed by the guiding mechanism 45, effectively preventing the drilling direction from deviating. During drilling, the cuttings are discharged outside the fixing ring 2 by the cuttings removal mechanism 6, and the cuttings are isolated from the adjusting mechanism 4 by the rubber pad 13, preventing the cuttings from affecting the adjusting mechanism 4 and further preventing the drilling direction of the drill rod 3 from deviating.

[0049] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
