Description

Technical Field

[0001] The utility model relates to the field of disassembly and assembly tools for carbon dioxide fire extinguishing gas cylinders used in a fire extinguishing system of a combustion engine generator box, in particular to a disassembly and assembly device for a carbon dioxide fire extinguishing gas cylinder. Background Art

[0002] The LM6000 unit is derived from the General Electric (GE) CF6-80C_2 jet engine, widely used in civil aircraft such as the Boeing 747, McDonnell Douglas MD-11, and Airbus A300 and A310. The LM6000 unit is a dual-shaft, cold-end driven gas turbine. When operating at 60 rpm, it can be directly connected to the generator. When operating at 50 rpm, a speed reduction device is required to reduce the speed to 3000 rpm. Due to its cold-end drive, the 50-cycle generator unit has a total length of 20.9 meters. Axial exhaust can be conveniently directed to a waste heat boiler system for combined heat and power generation or combined cycle power generation. When operating at 60 rpm in a simple cycle, the LM6000 unit has a heat rate of 9,062 kJ / (kW·h) and an output power of 40,760 kW, making it one of the most efficient and high-performance gas turbine generator sets in the world.

[0003] The fire extinguishing system of the gas turbine generator box is a very important and necessary item. The fire extinguishing material of the current gas turbine fire extinguishing system is composed of multiple carbon dioxide fire extinguishing cylinders. Once a fire occurs, the carbon dioxide in the carbon dioxide fire extinguishing cylinders will be instantly sprayed in to extinguish the fire, providing protection for the fire prevention of the gas turbine. The carbon dioxide fire extinguishing cylinders need to be replaced when the gas is used up or leaking; and as special equipment, the carbon dioxide fire extinguishing cylinders must be inspected regularly. If they are broken, they need to be repaired immediately. However, due to the lack of special tools, each cylinder must be disassembled when it is replaced or inspected. Moreover, since the carbon dioxide fire extinguishing cylinders are large in size and very heavy, and are also located at high places, each disassembly and assembly is very time-consuming, wasting a lot of manpower and material resources.
