Description

Technical Field

[0001] This utility model belongs to the technical field of underground nail guns, specifically relating to a portable pneumatic nailing device for underground rescue. Background Technology

[0002] When dealing with underground fires, rescue teams sometimes need to build temporary air barriers, wooden board enclosures, or other facilities to change the airflow, or to seal off large areas of the fire zone. Building these facilities tests a team's ability to cooperate and coordinate, and it is also a race against time. Every minute that the sealing work can be completed earlier can reduce the danger.

[0003] Existing conventional pneumatic nailing equipment generally suffers from the following drawbacks when applied to underground mining operations: First, it requires an independent air source (such as a compressed air tank) or an external fixed air pump, making it inconvenient to carry and unsuitable for mobile rescue scenarios underground; second, core components (such as pressure gauges and pressure reducers) are all standardized new products, resulting in high manufacturing costs and making it impossible to utilize existing scrapped equipment resources; third, it requires numerous equipment parts, is inconvenient to move, and wastes valuable time in underground rescue operations. Therefore, there is an urgent need for a low-cost and efficient pneumatic nailing device that is suitable for mine rescue scenarios. Utility Model Content

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] This utility model provides a portable pneumatic nail-driving device for downhole rescue, such as... Figure 1 As shown, it includes: a base 7, with four wheels 10 at its bottom; and a guardrail 9, which is a ring structure and is positioned above the base 7.

[0022] Oxygen cylinder 2 is placed vertically within the guardrail 9; the height of the guardrail 9 must exceed half the height of oxygen cylinder 2 to ensure that oxygen cylinder 2 does not tip over during movement. A pressure reducing valve 4 and a three-outlet distributor 5 are sequentially connected to the outlet of oxygen cylinder 2. Each of the three outlets of the three-outlet distributor 5 is connected to a flexible hose 6; the flexible hose 6 is used to transmit compressed air, connect various components, and ensure the air circuit is sealed. The three-outlet distributor 5 allows for the connection of multiple nail guns 2 at once, greatly improving work efficiency.

[0023] A support platform 11 is positioned above the base 7, on which three fixed posts 12 are mounted; three flexible hoses 6 are used to wrap around the fixed posts 12 respectively; when not in use, the long flexible hoses 6 are wrapped around the fixed posts 12 for easy storage and movement of the entire nailing device.

[0024] Three hooks 13, all L-shaped, are longitudinally spaced on the outer side of the support platform 11 for hanging three pneumatic nail guns 1. The pneumatic nail gun 1 is the core component for performing the nailing action, with a built-in firing mechanism and magazine (capacity 80pcs of nails). The three hooks 13 allow the nail guns 1 to be hung on the hooks when nailing is not needed, facilitating storage and transportation.

[0025] This utility model discloses a portable pneumatic nail-driving device for underground rescue, which significantly improves work efficiency. The pneumatic nail gun is equipped with an 80-piece high-capacity magazine, which greatly reduces the frequency of magazine changes compared to the 10-30 round magazine capacity of traditional air guns. With the quick-connect design, the entire process from installation to startup only requires three steps: "connecting the air source - loading nails - opening the valve". It can be operated by a single person, significantly shortening the time required to build windbreaks or airtight walls, and saving valuable time for fire rescue.

[0026] The oxygen cylinder 2 is a backup oxygen cylinder for downhole rescue, used to provide air pressure for the nail gun 1. This portable pneumatic nail gun for downhole rescue exhibits outstanding adaptability and portability in terms of air source. It directly utilizes the backup oxygen cylinder standardly provided by the rescue team as a power source, eliminating the need to carry separate gas cylinders or connect to external air pumps, reducing the load on downhole equipment, and making it particularly suitable for rapid deployment in emergency rescue scenarios. The oxygen cylinder's rated pressure of 20MPa is reduced to a working pressure of 0.5-0.8MPa via a pressure reducer, ensuring nail-driving power while allowing for real-time pressure monitoring via a pressure gauge to avoid overpressure risks and improve operational safety.

[0027] The pressure reducing valve 4 is used to reduce the output pressure of the oxygen cylinder 2 to match the working pressure of the nail gun 1, thereby quickly sealing off wind barriers, building wooden board seals and other facilities that change the airflow. The construction of these facilities tests the team's ability to cooperate and coordinate, and it is also a race against time. The sooner the sealing work is completed, the less danger there will be. This invention can greatly shorten the time it takes for commanders and soldiers to nail, thereby completing the work quickly.

[0028] In some embodiments, a 360° swivel joint is provided at the connection point of the hose 6 between the three-outlet distributor 5 and the pneumatic nail gun 1, and a filter screen is provided at the outlet of the swivel joint. This allows the hose 6 to rotate freely at any angle, avoiding operational obstruction caused by hose tangling when multiple people are working simultaneously, and improving the efficiency of on-site collaboration. It enables a single person to complete equipment handling and multi-gun collaborative operations, reducing labor costs by 50% compared to the traditional operation mode that requires two people, making it particularly suitable for small team rapid response scenarios.

[0029] In some embodiments, a pressure gauge 3 is provided on the pressure reducing valve 4. This pressure gauge, from a discarded 2-hour oxygen respirator, is used to monitor the airway pressure in real time.

[0030] In some embodiments, the base 7 is provided with a handrail 8.

[0031] The method of using the portable pneumatic nail-driving device for downhole rescue according to this utility model is as follows:

[0032] Before use, place the oxygen cylinder 2, which is a spare for well rescue, inside the guardrail 9; seal the outlet end of the oxygen cylinder 2 to the inlet end of the pressure reducing valve 4; connect the pneumatic nail gun 1 to the three-outlet distributor 5 through the hose 6 and ensure airtightness; then load the appropriate size of the pneumatic nail gun 1 into the magazine compartment of the pneumatic nail gun 1 to complete the equipment assembly.

[0033] When using the device, push the portable pneumatic nailing equipment for downhole rescue to the location in the well where rescue is needed; turn on the switch of oxygen cylinder 2, observe the value of pressure gauge 3, and confirm that the pressure reducing valve 4 stabilizes the pressure within the range of 0.5-0.8MPa; after the airflow stabilizes, hold the pneumatic nail gun 1, aim it at the location to be nailed, press the firing wrench, and use air pressure to push the nail into the target object; during continuous nailing, monitor pressure gauge 3 in real time, and when the pressure is lower than the safety threshold, immediately turn off the switch of oxygen cylinder 2 and replace it with a spare oxygen cylinder 2.

[0034] After completing the operation, first turn off the oxygen cylinder 2 switch, then press the firing wrench several times to release the residual air in the nail gun and ensure that there is no residual air pressure in the equipment.

[0035] This invention, by mounting the integrated nailing device on a movable base, allows for faster and more convenient access to underground rescue sites. The three-outlet distributor allows for the connection of multiple nail guns simultaneously, significantly improving work efficiency. When not in use, the long flexible hose can be wound around a fixed post for easy storage and relocation of the integrated nailing device. Three hooks are provided for hanging the nail guns when not in use, facilitating storage and transport.

[0036] This utility model relates to a portable pneumatic nail-driving device for underground rescue, which utilizes old equipment to reduce costs. The core components are salvaged parts from discarded mine rescue equipment—the pressure gauge and resuscitator pressure reducer of a discarded 2-hour oxygen respirator. This significantly reduces manufacturing costs, aligns with the green and energy-saving concept of "repairing and reusing old equipment," and simultaneously achieves the secondary use of scrapped equipment, reducing resource waste.
