Technical Field

[0001] The utility model relates to the technical field of emergency rescue auxiliary equipment, in particular to an emergency rescue breaking and demolition device. Background Art

[0002] When an equipment collapse accident occurs in an oil refinery or chemical plant due to equipment collapse or explosion, the collapsed steel structures, pipelines or equipment are often easily piled up in the passage, causing the passage to be blocked, affecting the actions of rescue workers. However, since the collapse site of an oil refinery or chemical plant is prone to be filled with flammable gases or liquids, in order to avoid the risk of secondary explosion, traditional flame cutting methods cannot be used, thus affecting the rescue speed. Utility Model Content

[0003] The utility model aims to provide an emergency rescue breaking and demolition device to solve the above problems existing in the prior art.

[0004] The technical solution of the utility model to solve the above technical problems is as follows:

[0005] An emergency rescue and demolition device comprises a bottom plate, wherein a plurality of liquid nitrogen pressure storage tanks are arranged on the upper surface of the bottom plate, and the tops of the plurality of liquid nitrogen pressure storage tanks are connected to liquid infusion pipelines and gas infusion pipelines, and valves are fixedly installed on the liquid infusion pipelines and the gas infusion pipelines; and further comprises a pneumatic impactor, a liquid nitrogen nozzle and a connecting piece;

[0006] The connecting piece includes a connecting pipe, and a first pair of joints and a second pair of joints that match. The first pair of joints are fixedly installed at both ends of the connecting pipe, and the second pair of joints are fixedly installed at one end of the liquid infusion pipe, the gas pipeline, the pneumatic impactor, and the liquid nitrogen nozzle. The pneumatic impactor is connected to the gas pipeline through the connecting piece, and the liquid nitrogen nozzle is connected to the liquid infusion pipe through the connecting piece.

[0007] The beneficial effect of the utility model is as follows: when the rescue team members are advancing inside the channel, a collapsed steel structure appears in front of them, and the staff holds the liquid nitrogen nozzle, starts the valve on the infusion pipeline, and sprays liquid nitrogen on the steel structure that needs to be demolished, so that the local temperature of the steel structure is lower than -100°C. At this temperature, the toughness of the steel structure itself will be reduced, resulting in lower strength. At this time, the staff holds the pneumatic impactor, opens the valve on the gas pipeline, and makes the pneumatic impactor impact the steel structure at this location, which can destroy the steel structure at this location, thereby achieving the purpose of demolition. No open flame will be generated during the entire operation process. The nitrogen generated by the exhaust gas and the gasification of the sprayed liquid nitrogen after the pneumatic impactor is operated can also create a local environment that isolates oxygen and combustible gases at the operation site. Even if sparks appear during the operation, it can be ensured that no fire or explosion will occur, thereby reducing the risk and improving practicality.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, a fixing part is provided on the upper surface of the bottom plate; the fixing part includes a fixing plate fixedly installed on the upper surface of the bottom plate, including a plurality of fixing seats fixedly installed on the upper surface of the bottom plate and located on both sides of the fixing plate for fixing the bottom of the liquid nitrogen pressure storage tank, and also includes a fixing ring fixedly installed on both side surfaces of the fixing plate and located above the plurality of fixing seats for fixing the surface of the liquid nitrogen pressure storage tank.

[0010] Furthermore, rubber pads are fixedly mounted on the inner walls of the plurality of fixing seats and the plurality of fixing rings.

[0011] Furthermore, a storage box is fixedly mounted on the upper surface of the bottom plate, and placement boxes are fixedly mounted on both side surfaces of the storage box. The pneumatic impactor and the liquid nitrogen nozzle can be placed inside the corresponding placement boxes.

[0012] Furthermore, a plurality of partitions are fixedly mounted on the inner wall of the storage box, and brackets are fixedly mounted on the inner walls on both sides of the storage box and between two adjacent partitions.

[0023] The connecting piece 8 includes a connecting pipe 81, and a matching first pair of joints 82 and a second pair of joints 83. The first pair of joints 82 are fixedly installed at both ends of the connecting pipe 81, and the second pair of joints 83 are fixedly installed at one end of the liquid infusion pipeline 3, the gas pipeline 4, the pneumatic impactor 6 and the liquid nitrogen nozzle 7. The pneumatic impactor 6 is connected to the gas pipeline 4 through the connecting piece 8, and the liquid nitrogen nozzle 7 is connected to the liquid infusion pipeline 3 through the connecting piece 8.

[0024] When the rescue team advances inside the channel, a collapsed steel structure appears in front of them. The staff holds the liquid nitrogen nozzle 7, starts the valve 5 on the infusion pipeline 3, and sprays liquid nitrogen on the steel structure that needs to be demolished, so that the local temperature of the steel structure is lower than -100°C. At this temperature, the toughness of the steel structure itself will be reduced, resulting in lower strength. At this time, the staff holds the pneumatic impactor 6 and opens the valve on the gas pipeline 4, so that the pneumatic impactor 6 impacts the steel structure at this location, which can destroy the steel structure at this location, thereby achieving the purpose of demolition. No open flame will be generated during the entire operation. The nitrogen generated by the exhaust and spraying of liquid nitrogen after the operation of the pneumatic impactor 6 can also create a local environment that isolates oxygen and combustible gases at the operation site. Even if sparks occur during the operation, it can be ensured that no fire or explosion will occur, thereby reducing the risk.

[0025] It should be noted that the pneumatic impactor 6 and the liquid nitrogen nozzle 7 can be quickly connected to the liquid nitrogen pressure storage tank 2 through the connecting piece 8. When the device is not in use, the pneumatic impactor 6 and the liquid nitrogen nozzle 7 can be quickly disassembled for convenient storage.

[0026] It should be noted that the liquid nitrogen pressure storage tank 2 is a low-temperature insulated storage tank, which can deliver liquid nitrogen to the liquid nitrogen nozzle 7 through the liquid delivery pipeline 3 and deliver nitrogen to the pneumatic impactor 6 through the gas delivery pipeline 4, thereby providing power for the pneumatic impactor 6, so that the pneumatic impactor 6 does not need to introduce additional power, thereby reducing cost consumption.

[0027] It should be noted that the liquid nitrogen pressure storage tank 2 is generally provided with an air bath type vaporizer, so that the nitrogen absorbs the heat of the air through the vaporizer and is vaporized into nitrogen close to the environment, and the valve 5 is a pressure reducing valve, which can reduce the nitrogen pressure to the required pressure value and directly supply the gas.
