Description

Technical Field

[0001] The utility model relates to the technical field of aircraft engine transport and test-run devices, in particular to a multifunctional aircraft engine transport and test-run device. Background Art

[0002] In the aircraft engine manufacturing and testing process, the completion of the final assembly of the engine marks a key step towards final performance testing. However, this transition stage is often accompanied by complex logistical challenges, especially when faced with specific test bench configurations. After the engines have completed all necessary assembly processes in the final assembly workshop, they need to be carefully transferred to a dedicated engine transporter so that they can be safely and stably transported to the test bench for the first test run. This standard process - seamless connection from the workshop to the transporter, then to the pre-assembly vehicle, and the subsequent test run on the test bench and the reverse return to the transporter - should be efficient and smooth.

[0003] However, in practice, the unique design of some test stands—using an upper transport system rather than a traditional overhead crane—presents significant challenges to this process. This limitation means that engines cannot be reversed directly from the transport vehicle to the pre-assembly area, but must instead be transferred to the test room. This process not only prolongs the overall cycle time from engine assembly to test, but also inevitably leads to congestion between process steps, reducing overall production efficiency.

[0004] Furthermore, the complexity of the installation site environment exacerbates this problem. Multiple engine frames of varying sizes and series are often placed simultaneously on site, occupying valuable space and increasing the complexity of operator judgment and operation, thus increasing the risk of error. Performing reverse operations in such an environment not only requires a high degree of professional skill and caution, but also requires overcoming spatial limitations and visual obstructions, further extending the operation time and increasing both time and labor costs.
