Description

Technical Field

[0001] The utility model relates to the field of turbofan engines, in particular to turbofan engine hoisting equipment. Background Art

[0002] The turbofan engine is a power device widely used in aviation, aerospace and ground power generation. Its working principle is to eject the high-temperature and high-pressure gas generated by fuel combustion through jet propulsion, generating a reaction force to propel the aircraft forward. The turbofan engine has the advantages of high efficiency, low noise and low emissions, and has become one of the core technologies of the modern aviation industry. The development of the turbofan engine can be traced back to the early 20th century, when jet engines mainly used turbojet engines (Turbojet) and turboprop engines (Turboprop). The thrust of the turbojet engine comes from the high-speed ejected gas, but its fuel consumption rate is high and it is not suitable for long-term low-speed flight. The turboprop engine generates thrust by driving a multi-blade propeller. Its fuel consumption rate is low, but the thrust is small and the noise is large. Due to the large size of the turbofan engine, the turbofan engine needs to be hoisted. The main reason why the turbofan engine needs to be hoisted is to install it on the aircraft. The turbofan engine is a complex thermal machine with high temperature, high pressure and high-speed rotation. It consists of tens of thousands of parts, with a complex and compact structure and a small space. In addition, the temperature changes dramatically during operation, and the internal flow is extremely complex, resulting in a very harsh environment for each structural component. Therefore, to safely and accurately install such a complex device on an aircraft, it needs to be hoisted. During hoisting, the turbofan engine needs a machine to turn the turbofan engine due to its heavy weight. At the same time, in order to reduce the blind spot of the turbofan engine during hoisting, the turbofan engine needs to be tilted to observe the turbofan engine, thereby reducing the time and energy of the turbofan engine during detection. In the prior art, the rotation and tilting of the turbofan engine requires the use of various large-scale machinery, which not only increases the cost significantly, but also increases the cost of manual operations. For this reason, we propose a turbofan engine hoisting device. Utility Model Content
