Abstract

The invention provides an anti-falling foldable heavy aircraft jack, and relates to the technical field of aviation equipment. The anti-falling foldable heavy aircraft jack comprises a plurality of supporting rods (1), an actuating cylinder (2), adjustable flat foot supporting palms (4) and pressed self-contraction trundles (5), wherein a T-shaped threaded piston (12) is installed in the actuating cylinder (2), a mechanical self-locking screw disc (3) is arranged at the top of the actuating cylinder (2), a leveling display pendulum bob (8) is installed on a shell, the bottom of the actuating cylinder is connected with a hydraulic pump station, the adjustable flat foot supporting palms (4) are connected with the supporting rods (1) through ball head leveling lead screws (13), and auxiliary supporting rods (6) are connected between the supporting rods (1) and the actuating cylinder (2) and between every two adjacent adjustable flat foot supporting palms (4). According to the anti-falling foldable heavy aircraft jack, safe jacking during maintenance of a large-scale heavy-load aircraft can be met, falling of the aircraft during hydraulic failure is avoided, the jack can be used for jack leveling on the uneven ground, and folding transportation along with the aircraft during aircraft transition is facilitated.

Description

technical field [0001] The invention relates to the technical field of aviation equipment, in particular to a foldable heavy-duty aircraft jack for preventing falling. Background technique [0002] The jack is a kind of working device that uses a rigid lifting piece as a working device. It lifts heavy objects within the stroke through the top bracket or the bottom claw. Currently, the commonly used jacks are mostly used in fields such as auto repair and lifting. Due to the weight of the aircraft itself Large, conventional jacks are not suitable. At present, most aircraft special jacks, such as patent number CN201510524362.5, an aircraft main jack adjustment device discloses an aircraft main jack adjustment device. , the supporting mechanism includes a first connecting rod, an adjustable foot, a second connecting rod and a third connecting rod, the two ends of the third connecting rod are respectively connected with the adjustable feet to form a tripod, and one end of the fir...
