Abstract
Description
technical field
[0001] The invention belongs to aircraft suspension support technology, in particular to an aircraft air spring lifting support. Background technique
[0002] Aircraft suspension support technology is a support suspension technology during aircraft ground testing, which is used to simulate the free-free state of the aircraft in the air. Existing aircraft suspension support technology mainly adopts lifting base with leading screw and telex type lifting base. The lifting base with lead screw mainly achieves the purpose of lifting by rotating the lead screw. The disadvantages are: 1) time-consuming and laborious (rotating the lead screw by manpower); 2) it is not suitable for large-tonnage aircraft; 3) it cannot be synchronized at three points Lifting; 4) Poor safety. The fly-by-wire lifting base is mainly driven by a motor to rotate the screw to achieve the purpose of lifting. The disadvantage is that it is not suitable for large-tonnage aircraft.

Embodiment Construction
[0012] Below in conjunction with embodiment and accompanying drawing, the present invention will be further described:
[0013] The aircraft air spring lifting support of the invention includes a hydraulic station, a hydraulic lifting cylinder, a base, an auxiliary support, an air spring installation base plate, a control valve group, and a displacement sensor.
[0014] The air spring installation base plate is a circular flange structure, which is set on the base for installing the air spring. Three hydraulic sound drop cylinders and three auxiliary supports are arranged around the air spring at intervals and evenly distributed on the air spring installation base plate In addition, the hydraulic lifting actuators are all provided with control valve groups and connected to the hydraulic station, and the displacement sensors are arranged on the side walls of the hydraulic lifting actuators.
[0015] The lower end of the base is provided with reinforcing ribs, the purpose of whi...
