Problems solved by technology

After completing the maintenance work, open the pressure relief valve of the axle jack, and rely on the gravity of the aircraft, the landing gear of the aircraft will press down on the actuator. The landing gear of the aircraft is locked together by concave-convex fit, which makes it difficult to take out the jack from the landing gear of the aircraft. At this time, it is necessary to compress the actuator manually, and it is very difficult to compress the actuator manually, which seriously affects the work efficiency. and flight punctuality and safety

Embodiment Construction

[0022] The present invention is further described below in conjunction with embodiment.

[0023] Such as figure 1 , figure 2 , image 3 As shown, the present invention includes a spray head 1 and a body 2 .

[0024] The shape of the spray head 1 is a round tube, with a convex ring 13 in the middle of its outer surface, its inner hole is the first air flow channel 11, its inlet end 12 is a threaded counterbore, and the outlet end 16 is a fine hole, located on the side of the outlet end of the convex ring There are threads on the outer surface of the outlet end 16, and the outer surface of the outlet end 16 is a conical nozzle 15. There is a conical wall 17 at the junction of the threaded counterbore of the inlet end 12 and the fine hole of the outlet end 16, and the air flow flows through the first air flow. During passage 11, transfer from the threaded counterbore of large diameter to the fine hole of small diameter, can form the air-flow that pressure is bigger, speed fas...

Abstract

The invention discloses an actuating cylinder recovering device for an aircraft axle jack. The actuating cylinder recovering device for the aircraft axle jack comprises a spray head and a main body, wherein the spray head is of a circular tube shape, and a convex ring is formed in the middle of the outer surface of the spray head; an inner hole of the spray head is used as a first air flowing channel; an inlet end of the spray head is provided with a threaded sunken hole while an outlet end of the spray head is provided with a fine hole; threads are formed in the outer surface at the outlet end side of the convex ring, and the outer surface of the outlet of the convex ring is provided with a tapered nozzle; the main body is pipe-shaped, and an inner hole of the main body is used as a second air flowing channel; a threaded sunken hole is formed in the inlet end of the main body and is in match with the outer threads in the outlet end of the spray head; a threaded sunken hole is formed in the outlet end of the main body; a threaded hole is drilled in the sidewall of the outer surface of the inlet end and communicates with the bottom of the threaded sunken hole in the inlet end; the spray head is in thread connection with the inlet end of the main body. With the adoption of the device, the actuating cylinder of the axle jack can lower down at constant speed; in addition, the device is simple in structure, convenient to operate, stable to run, and high in efficiency.

Description

technical field [0001] The invention relates to a device for recovering an aircraft axle jack actuator. [0002] technical background [0003] Pneumatic hydraulic pumps can convert lower air pressure into high oil pressure, that is, use low air pressure at the piston end with a large area to generate high hydraulic pressure at the piston end with a small area, so the air hydraulic pump will have a gas chamber. During the maintenance process of the aircraft, it is usually necessary to use the axle jack to support the landing gear of the aircraft, so that the maintenance personnel can overhaul and replace the tires. The axle jack realizes its function by lifting the actuator through the pneumatic hydraulic pump. After completing the maintenance work, open the pressure relief valve of the axle jack, and rely on the gravity of the aircraft, the landing gear of the aircraft will press down on the actuator. The landing gear of the aircraft is locked together by concave-convex fit,...
