Embodiment Construction

[0013] An external pedal for a helicopter is composed of a rear fixing part 1, a strut 2, an adapter joint 3, a front fixing part 4, a connecting clamp 5 and a beam 6, and the components can be disassembled.

[0014] The front end and the rear end of the crossbeam 6 are respectively docked with the sleeves of the front fixture 4 and the rear fixture 1, and a strut 2 is arranged between the lower end of the front fixture 4 and the front end of the crossbeam 6, and the strut 2 is connected by a clamp 5 is connected to the front end of the crossbeam 6, and a strut 2 is arranged between the lower end of the rear fixing member 1 and the rear end of the crossbeam 6, and the strut 2 is connected to the rear end of the crossbeam 6 through a connecting clip 5.

[0015] The front fixing part 4 and the rear fixing part 1 are riveted on the main load-bearing frame below the floor plane of the helicopter, and the front fixing part 4 uses an adapter joint to strengthen the connection effect,...

Abstract

The invention belongs to the technical field of helicopter structural members, and particularly relates to an externally-hung pedal of a helicopter. The externally-hung pedal comprises a rear fixing piece (1), supporting rods (2), an adapter connector (3), a front fixing part (4), connecting hoops (5) and a cross beam (6), wherein the front end and the rear end of the cross beam (6) are in butt joint with a sleeve of the front fixing part (4) and a sleeve of the rear fixing part (1) respectively; the lower end of the front fixing part (4) is connected with the front end of the cross beam (6) through one supporting rod (2), and the supporting rod (2) is connected with the front end of the cross beam (6) through the corresponding connecting hoop (5); the other supporting rod (2) is arranged between the lower end of the rear fixing piece (1) and the rear end of the cross beam (6), the supporting rod (2) is connected with the rear end of the cross beam (6) through the corresponding connecting hoop (5), and the front fixing part (4) and the rear fixing part (1) are riveted to a main bearing frame below a floor plane of the helicopter. The front fixing part (4) uses the adapter connector to enhance the connecting effect, and meanwhile, the function of ensuring ground mooring at the position is achieved. The connecting hoops (5) are two semi-circular rings and are arranged on the cross beam in a sleeving mode (6), one end of each connecting hoop is fixed through a bolt, and the other end of each connecting hoop is connected with corresponding supporting rod (2).

Description

technical field [0001] The invention belongs to the technical field of helicopter structural parts, in particular to a helicopter external pedal. Background technique [0002] For the convenience of passengers getting on and off the helicopter, wheeled landing gear helicopters are mostly designed with built-in boarding pedals and equipped with a lock mechanism. When using the pedals, ground personnel need to unlock the locks, and the ground personnel will lock them after passengers board the aircraft. The lock mechanism is locked, which is inconvenient to operate, and the maintenance work of the lock mechanism is increased in daily maintenance. In addition, most of the current helicopters need to perform a variety of tasks. For example, after installing an electric winch and a cable drop mechanism, the helicopter can perform the tasks of delivering people to the ground and performing rescue tasks. However, since there is no effective support point outside the helicopter, th...
