Abstract

The invention provides a helicopter blade clamping and locking device. The helicopter blade clamping and locking device comprises a pressing plate (1), a supporting plate (2), a J-shaped piece (3), a short connecting rod (4), an adjustable locking rod, a long connecting rod (6), a long shaft (7) and a push rod (8). The pressing plate (1) is rotationally connected to a first rotating shaft (101) on the supporting plate (2); the two ends of the adjustable locking rod are rotationally connected with the pressing plate (1) and the first end of the J-shaped piece (3); the second end of the J-shaped piece (3) is rotationally connected with the first end of the short connecting rod (4), and the third end is rotationally connected with the supporting plate (2); the second end of the short connecting rod (4) and the first end of the long connecting rod (6) are rotationally sleeved on the long shaft (7); the second end of the long connecting rod (6) is rotationally connected with the supporting plate (2); the push rod (8) is hinged to the long shaft (7) and used for pushing the long shaft (7) to move; and the supporting plate (2) is provided with a supporting groove used for clamping the long shaft (7). And rapid clamping and locking are achieved.

Description

technical field [0001] The invention belongs to the design field of a helicopter rotor folding device, in particular to a helicopter blade clamping and locking device. Background technique [0002] When the helicopter is shipped on a carrier platform such as a ship or a large transport aircraft, the rotor needs to be folded and fixed to reduce the transportation and storage space of the helicopter, and at the same time avoid the blades from interfering with the loading platform during the waving and shimmy motion during transportation. damage. [0003] However, due to many reasons such as the unique shape of the blade airfoil and the large inertial load during sea and air transportation, it is difficult for ordinary universal clamps to meet the needs of fast clamping and locking. Contents of the invention [0004] The invention provides a clamping and locking device for helicopter blades, which realizes fast clamping and locking of the blades when the helicopter is loaded...
