Description

Technical Field

[0001] This invention relates to a self-propelled lifting device for aircraft engine disassembly operations, belonging to the field of aviation equipment. Background Technology

[0002] In recent years, with the improvement of my country's comprehensive national strength, the country has vigorously developed related industries. With the booming development of aviation and aerospace construction, intelligent mechanical equipment used in this field, as a part of it, has also developed at an unprecedented speed and scale. A construction boom in related fields has swept across the country, and a large number of newly built and renovated factories urgently need high-tech equipment. This has led to a rapid expansion of the domestic market, prompting related mechanical equipment to develop towards industrialization, forming a market with huge potential and broad prospects. On the one hand, my country has basically achieved the localization of the design and manufacturing of special mechanical equipment for the disassembly of key aviation components, and the level of mechanical technology has developed rapidly. However, my country's related equipment technology is relatively backward. Currently, there are very few manufacturers in China that can truly design and manufacture independently, which is far from meeting the needs of the current rapid development. This has also led to major international companies entering the Chinese market in large numbers, seizing most of the mid-to-high-end market share. Therefore, vigorously developing related technologies in my country is of great practical significance for improving the overall technical level of the country, improving the working conditions of operators, and promoting social development. On the other hand, the development of specialized mechanical equipment for the disassembly of key aviation components in my country is relatively late, lacking solid theoretical research and design experience, and still has some problems. Completely copying and imitating foreign platform designs is not suitable for my country's national conditions. Due to the high processing difficulty and use of a large number of specialized components in large machinery, domestic procurement is difficult and costly, which also limits the application of specialized mechanical equipment for the disassembly of key aviation components in related fields in my country. However, with the development of my country's aviation and aerospace industry, construction is also becoming more diversified, and current design forms are diverse, making it impossible to adopt general-purpose standardized specialized equipment. At present, with the development of control technology, computer technology, and electric drive technology, there is a trend internationally for computer-controlled modular combination equipment to replace large integral frame mechanical equipment. Miniaturized combination equipment can meet the use of disassembly operations for different types of key aviation components, expanding the application range of equipment; it can achieve better results and is more suitable for large-scale promotion in this field. There is a gap between the disassembly table and the manned platform of the existing aircraft engine disassembly equipment. During the disassembly process, some parts often fall out of the gap between the disassembly table and the manned platform, causing engine parts to be scattered all over the ground and unable to be collected together for easy access, which affects the disassembly process.

The multiple driven wheels 303 are evenly distributed and mounted on the lower surface of the equipment base 5, and the axis of the axle of each driven wheel 303 is parallel to the axis of the axle of the drive wheel 302. The drive motor 301 is equipped with a three-axis gearbox. The input shaft of the three-axis gearbox is coaxially and fixedly connected to the motor shaft of the drive motor 301, and the two output shafts of the three-axis gearbox are coaxially and fixedly connected to the axles of the two drive wheels 302, respectively.

[0036] With this configuration, the self-propelled mechanism 3 can move and operate smoothly on the ground, and ensure that the equipment base frame 5 experiences minimal vibration during movement.

The rack 510 is positioned between two right slide rails 503, and the centerline of the rack 510 along its length is parallel to the centerline of the right slide rail 503 along its length. A gap is left between the gear 509 with electromagnetic locking function and the rack 510.

[0042] There is a certain gap between the gear 509 with electromagnetic locking function and the rack 510 to ensure that they do not mesh. When the equipment needs to be locked, the gear block guide electric push rod 511 pushes the gear 509 with electromagnetic locking function to mesh and lock with the rack 510. In case of emergency such as sudden power failure, the gear 509 with electromagnetic locking function will automatically lock the gear rotation. The equipment will be locked at any time during the start and end of the lifting process to ensure the safety and stability of the equipment during the lifting process.
