Description
Technical Field
[0001] This invention relates to the field of mine rescue technology, and in particular to an emergency obstacle-breaking and rescue device for mines. Background Technology
[0002] Underground coal mining operations are highly susceptible to various safety disasters such as collapses. After an accident, rescuers usually use life detectors and hazardous gas monitoring equipment to determine the approximate location, vital signs, and environmental conditions of trapped personnel in the affected area. In underground emergency rescue operations, handheld drilling rigs are the core portable equipment for mine emergency obstacle clearing and personnel search and rescue. They can complete a number of key operations at the rescue site, such as drilling and ventilation, material transportation, rock anchoring and support, obstacle drilling and breaking, and close-range search and rescue exploration.
[0003] Existing handheld rescue drills are generally heavy and bulky, making them difficult for a single person to operate independently. Drilling operations require the cooperation of multiple people. In addition, the mine collapse site is characterized by piles of rocks and uneven working surfaces, often with irregular curved surfaces. Rescue personnel cannot stably calibrate the drilling position of the drill, which can easily cause the hole to be skewed or the borehole to deviate. This often requires repeated drilling operations, which seriously slows down the overall rescue progress.
[0004] Therefore, in order to effectively improve the ease of operation and actual work efficiency of rescue drilling rigs and further optimize the effectiveness of underground emergency rescue work, this invention provides an emergency obstacle-breaking and rescue device for mines to meet the needs. Summary of the Invention
[0005] The technical problem this invention aims to solve is to provide an emergency obstacle-breaking and rescue device for mines. By setting up a support mechanism and a drilling mechanism, this rescue device provides an adjustable support system for the drilling rig, thereby eliminating the need for rescue personnel to manually operate the drilling rig, making drilling operations easier and improving the efficiency of drilling rescue. This adjustable support system can also adaptively adjust the drilling position of the drilling rig according to the on-site conditions of the mine after a collapse and the accumulation of rubble, further improving rescue efficiency and the ease of use of the device. Through the above settings, the problem of rescue personnel being unable to stably calibrate the drilling position of the drilling rig during the current drilling rescue process can be solved, which easily leads to hole deviation and duct offset, often requiring repeated drilling operations and seriously slowing down the overall rescue progress.
[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: An emergency obstacle-breaking and rescue device for mines includes a bottom support, a top support, and a drilling rig. The drilling rig is slidably mounted on the top of the top support. A support mechanism is installed on the top of the bottom support for fixing the relative position between the bottom support and the top support. The support mechanism includes a first support rod and a second support rod. The first support rod is hinged to one end of the bottom support, and the end of the first support rod away from the bottom support is hinged to the top support. The second support rod is fixedly connected to the end of the bottom support away from the first support rod. The device also includes a drilling mechanism, which includes a slide rod rotatably connected to the top support. One end of the slide rod is fixedly connected to a handwheel, and the other end of the slide rod is rotatably connected to an adjusting rod. A screw is coaxially provided on the outer side of the slide rod.
[0007] Optionally, an adjusting base is fixedly connected to the top of the bottom bracket, the second support rod is hinged to the adjusting base, and a threaded sleeve is provided at the hinge point between the second support rod and the adjusting base. The threaded sleeve is threadedly connected to both the second support rod and the adjusting base.
[0008] Optionally, an installation gap is reserved between the two second support rods, and an installation plate is installed in the installation gap. A first installation block and a second installation block are fixedly connected to the two ends and the center of the installation plate, respectively. A first rod clamp is fixedly connected to both the first installation block and the second installation block.
[0009] Optionally, both ends of the mounting plate are clamped and fixed to the outer wall of the second support rod by the first rod clamp, and the first rod clamp at the center of the mounting plate is clamped and fixed to the outer wall of the adjusting rod.
[0010] Optionally, the mounting plate, the first mounting block, and then the second mounting block are integrally bent sheet metal structures.
[0011] Optionally, the screw is threadedly connected to a threaded slide block, and two guide rods are symmetrically inserted on both sides of the threaded slide block. The guide rods are sequentially inserted into the top bracket and the threaded slide block, and the two ends of the guide rods are locked and fixed to the outer wall of the top bracket by nuts.
[0012] Optionally, both ends of the screw are fixedly connected to clamps, and the clamps are provided with clearance grooves.
[0013] Optionally, a second rod clamp is fixedly connected to the outer wall of the clamping plate, and the screw and the slide rod are clamped and fixed together by the second rod clamp.
[0014] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up a support mechanism and a drilling mechanism, this rescue device provides an adjustable support system for the drilling rig, thus eliminating the need for rescue personnel to manually operate the drilling rig, making drilling operations easier and improving drilling rescue efficiency. This adjustable support system can also adaptively adjust the drilling position of the rig according to the site conditions of the mine collapse and the piled-up rocks, further improving rescue efficiency and ease of use of the device. In addition, this rescue device is equipped with a propulsion mechanism with two operating states for the drilling rig's operation. These two operating states correspond to the rapid relocation operation before drilling and the precise feeding operation during drilling, respectively. This ensures both the convenience and efficiency of the rig's position adjustment before drilling and improves the uniformity of the rig's movement and the straightness of the hole during drilling. Thus, while improving drilling rescue efficiency, it also ensures the convenience and operational stability of rescue personnel when using the drilling rig.
[0015] The rescue device provided in this application has a simple structure and low manufacturing cost. It can be folded and stored during transportation, making it easier to move within the mine. In actual use, the structure is efficiently assembled, and the operation of adjusting the position of the drilling rig by rescue personnel is simple and convenient. Attached Figure Description

[0025] like Figures 1 to 8 As shown, an embodiment of the present invention provides an emergency obstacle-breaking and rescue device for mines, including a bottom support 1, a top support 3, and a drilling rig 4. The drilling rig 4 is slidably mounted on the top of the top support 3. A support mechanism is installed on the top of the bottom support 1. The support mechanism is used to fix the relative position between the bottom support 1 and the top support 3. The support mechanism includes a first support rod 2 and a second support rod 9. The first support rod 2 is hinged to one end of the bottom support 1, and the end of the first support rod 2 away from the bottom support 1 is hinged to the top support 3. The second support rod 9 is fixedly connected to the end of the bottom support 1 away from the first support rod 2. An adjusting base 8 is fixedly connected to the top of the bottom support 1. The second support rod 9 is hinged to the adjusting base 8. A threaded sleeve 10 is provided at the hinge point of the second support rod 9 and the adjusting base 8. The threaded sleeve 10 is threadedly connected to both the second support rod 9 and the adjusting base 8.
[0026] In the above structure, the drilling rig 4 is installed on top of the top support 3. Relying on the support of the bottom support 1 and the top support 3, the drilling rig 4 does not require manual operation by rescue personnel, making drilling operations easier and improving the efficiency of drilling rescue. By setting a support mechanism between the bottom support 1 and the top support 3, the relative position of the two can be adjusted and fixed. Specifically, one end of the bottom support 1 and the top support 3 is hinged together by the first support rod 2, so that the top support 3 can rotate on top of the bottom support 1 under the support of the first support rod 2. The other end of the top support 3 is supported and positioned by two second support rods 9. By rotating the first support rod 2, the relative height between the bottom support 1 and the top support 3 can be adjusted, thereby adjusting the drilling height of the drilling rig 4. This allows the rescue device to make adaptive adjustments to the drilling position of the drilling rig 4 according to the on-site conditions of the mine collapse and the piled rocks, further improving rescue efficiency and the ease of use of the device.
[0027] Furthermore, since the adjusting base 8 and the second support rod 9 are hinged together, and the threaded sleeve 10 is threadedly fixed at the hinge position of the adjusting base 8 and the second support rod 9, when the rescuer unscrews the threaded sleeve 10 from the hinge position of the adjusting base 8 and the second support rod 9, the second support rod 9 can rotate on the top of the adjusting base 8. This structural arrangement, combined with the hinged rotation structure between the bottom bracket 1 and the top bracket 3 via the first support rod 2, allows the entire device to be folded up. After folding (e.g., Figure 2 As shown in the figure, the overall space occupied is smaller, making it easier for rescuers to move and transport the device within the mine, further improving the ease of use of the device.
[0028] As one implementation method in this embodiment, such as Figures 1 to 9 As shown, the drilling mechanism includes a slide rod 5 rotatably connected to the top support 3. A handwheel 6 is fixedly connected to one end of the slide rod 5, and an adjusting rod 7 is rotatably connected to the other end. A screw 15 is coaxially mounted on the outer side of the slide rod 5, and a threaded slide block 19 is threaded onto the screw 15. Two guide rods 20 are symmetrically inserted through both sides of the threaded slide block 19. The guide rods 20 are sequentially inserted into the top support 3 and the threaded slide block 19. Both ends of the guide rods 20 are locked to the outer wall of the top support 3 by nuts. A space is reserved between the two second support rods 9. The mounting gap contains a mounting plate 11. The two ends and the center of the mounting plate 11 are respectively fixedly connected to a first mounting block 12 and a second mounting block 13. The first mounting block 12 and the second mounting block 13 are both fixedly connected to a first rod clamp 14. The two ends of the mounting plate 11 are clamped and fixed to the outer wall of the second support rod 9 by the first rod clamp 14. The first rod clamp 14 at the center of the mounting plate 11 is clamped and fixed to the outer wall of the adjusting rod 7. The mounting plate 11, the first mounting block 12 and the second mounting block 13 are a sheet metal structure formed by bending in one piece.
[0029] In the above structure, the handwheel 6 and the adjusting rod 7 are respectively installed at both ends of the slide rod 5. The adjusting rod 7 can rotate at the end of the slide rod 5, and the adjusting rod 7 and the mounting plate 11 are fixed by the first rod clamp 14. The two ends of the mounting plate 11 are also clamped and fixed by the first rod clamp 14 and the second support rod 9. Through the above structure, rescuers can change the relative height between the adjusting rod 7 and the bottom bracket 1 by adjusting the first rod clamp 14 at both ends of the mounting plate 11, and then change the relative position between the adjusting rod 7 and the mounting plate 11 by adjusting the first rod clamp 14 at the middle position of the mounting plate 11, thereby achieving the effect of adjusting the relative height between the bottom bracket 1 and the top bracket 3. This adjustment method is simple to operate, the top bracket 3 has high overall stability, and it is convenient for subsequent folding and storage of the device. In addition, since the mounting plate 11, the first mounting block 12 and the second mounting block 13 are integrally formed sheet metal structures, they not only have high structural strength, but also have simple production processes, low manufacturing costs, and are convenient for assembly and transportation.
[0030] Furthermore, when the rescuer turns the handwheel 6, the threaded slide 19 will slide on top of the top support 3 under the threaded transmission action of the screw 15 and the threaded slide 19. Since the drilling rig 4 is fixed on top of the threaded slide 19, the drilling rig 4 will slide synchronously with the threaded slide 19 as the threaded slide 19 slides on top of the top support 3. At the same time, the guide rods 20 on both sides of the threaded slide 19 can limit and guide the threaded slide 19, ensuring the stability of the overall structure of the threaded slide 19. Through the above structure, the rescuer does not need to manually calibrate the drilling position of the drilling rig 4, and can ensure that the drilling is straight and regular during operation, avoiding repeated rework of drilling and improving the overall efficiency of downhole drilling rescue operation.
[0031] In this embodiment, as Figures 1 to 11 As shown, both ends of the screw 15 are fixedly connected to clamping plates 16. A clearance groove 17 is provided through the clamping plate 16. A second rod clamp 18 is fixedly connected to the outer wall of the clamping plate 16. The screw 15 and the slide rod 5 are clamped and fixed together by the second rod clamp 18.
[0032] As mentioned above, rescuers can rotate handwheel 6 to make the drill 4 slide on top of the top support 3. Furthermore, the clamps 16 at both ends of the screw 15 are fixed to the slide rod 5 by means of the second clamp 18. Therefore, the fixing method between the screw 15 and the slide rod 5 can be changed by adjusting the second clamp 18. Specifically, when the rescuers adjust the second clamp 18 to release the clamping fixation of the clamp 16, the limit between the screw 15 and the slide rod 5 is released. At this time, the screw 15 can slide freely on the slide rod 5 to adjust its position. During the sliding of the screw 15, the drill 4 on the threaded slide 19 will move synchronously with the screw 15 on top of the top support 3. This operation allows the drill rig 4 to be moved quickly, enabling it to efficiently move to the drilling position. When the rescuer adjusts the second clamp 18 to clamp and fix the clamp plate 16 onto the slide rod 5, the screw 15 and the slide rod 5 become a complete support system. This support system is used to support the threaded slide block 19 and adjust the relative position of the threaded slide block 19 on the top of the top support 3. At this time, when the rescuer turns the handwheel 6, under the threaded transmission cooperation of the screw 15 and the threaded slide block 19, the threaded slide block 19 moves slowly along the top of the top support 3, thereby ensuring that the drill rig 4 moves at a uniform speed during drilling and ensuring that the drill hole is straight and regular.
[0033] In summary, by setting the second clamp 18 and the clamping plate 16, there are two operating states between the screw 15 and the slide bar 5. These two operating states correspond to the rapid shifting operation before drilling and the precise feeding operation during drilling. This ensures the convenience and efficiency of the position adjustment of the drilling rig 4 before drilling, and also improves the uniformity of the movement of the drilling rig 4 and the straightness of the hole during drilling. Thus, while improving the efficiency of drilling rescue, it also ensures the convenience and operational stability of rescue personnel when using the drilling rig 4.
[0034] The working principle of the first clamp 14 and the second clamp 18 in this technical solution is disclosed as mature prior art and will not be described in detail here.
[0035] The working principle of the technical solution provided by this invention is as follows: In use, rescuers first adjust the first clamp 14 to release the fixing effect between the mounting plate 11 and the second support rod 9 and the adjusting rod 7. Then, they rotate the top bracket 3 to adjust the relative height between the top bracket 3 and the bottom bracket 1. During the rotation of the top bracket 3, the first support rod 2 is simultaneously hinged between the bottom bracket 1 and the top bracket 3, which can ensure the stability of one end of the top bracket 3. The adjusting rod 7 will follow the direction of rotation of the top bracket 3 and move synchronously within the first clamp 14. At the same time, by adjusting the relative height between the mounting plate 11 and the second support rod 9, the top bracket 3 and the bottom bracket 1 are kept in a parallel state. When the height of the top bracket 3 is determined, the first clamps 14 at both sides and the middle position of the mounting plate 11 are locked and fixed. At this time, the two ends of the top bracket 3 are supported and positioned by the first support rod 2 and the adjusting rod 7 respectively, and the bottom bracket 1 and the top bracket 3 form a complete support system.
[0036] After the height of the top support 3 is determined, the rescuers first adjust the second rod clamp 18 to release the clamping and fixing of the clamp plate 16. At this time, the limit between the screw 15 and the slide rod 5 is released, and the screw 15 can slide freely on the slide rod 5 to adjust its position. During the sliding of the screw 15, the drill 4 on the threaded slide block 19 will move synchronously with the screw 15 on the top of the top support 3. Through this operation, the drill 4 can be moved quickly, so that the drill 4 can be moved to the position to be drilled efficiently.
[0037] When the drill rig 4 moves to the drilling position, the rescuer adjusts the second clamp 18 to clamp and fix the clamp plate 16 onto the slide rod 5. At this time, the screw 15 and the slide rod 5 become a whole support system. This support system is used to support the threaded slide 19 and adjust the relative position of the threaded slide 19 on the top of the top bracket 3. When the rescuer turns the handwheel 6, under the threaded transmission action of the screw 15 and the threaded slide 19, the threaded slide 19 moves slowly along the top of the top bracket 3, thereby ensuring that the drill rig 4 moves at a uniform speed during the drilling process and ensuring that the drill hole is straight and regular.
[0038] This invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this invention. To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0039] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
