Problems solved by technology
When hanging cargo, the load in the vertical direction drives the crank to rotate around the crank axis through the cargo hook, and is transmitted to the base of the reduction box through the connecting rod. The problem with this is that in order to balance the component force of the cargo perpendicular to the course deflection, the crank and its mounting base must bear a huge bending moment, and the design of the crank and its mounting base is extremely strong and heavy

Embodiment Construction
[0026] The present invention is described in further detail below in conjunction with accompanying drawing:
[0027] Such as figure 1 As shown, it is the helicopter load transmission and anti-sway structure according to the present invention, which includes a load bearing base 1 connected with the main gearbox of the helicopter, and the pull rod 4 is hung on the bearing through the first suspension ring 3 and the first pin shaft 2 at the upper end. On the force base 1, the lower end of the pull rod 4 is connected to the middle part of the upper load beam 7 through the second suspension ring 5 and the second pin shaft 6, so that the pull rod 4 can be flexibly rotated.
[0028] The upper load beam 7 is located above the lower load beam 9, such as figure 2 As shown, the lower bearing beam 9 is installed in the first upper bearing bush 16 and the first lower bearing bush 17 on the upper bearing beam 7, and the middle part of the first upper bearing bush shaft 16 and the first lo...

The invention discloses a helicopter load transmission and anti-deflection structure and a helicopter. The helicopter load transmission and anti-deflection structure comprises an upper bearing beam, a lower bearing beam and a hanging plate, wherein the upper bearing beam is located above the lower bearing beam, the middle of the upper bearing beam is connected with a bearing piece, the two ends of the upper bearing beam are bent towards the two ends of the lower bearing beam and rotationally connected with the two ends of the lower bearing beam, and the rotating direction is the circumferential direction of the lower bearing beam; a connecting piece is nested in the middle of the lower bearing beam and extends towards the two radial ends of the lower bearing beam in the horizontal direction, and the section of the extending end is round; and the top of the hanging plate is arranged in a forked mode, the two forks of the top of the hanging plate are rotationally connected with the two extending ends of the connecting piece respectively, and the rotating direction is parallel to the length direction of the lower bearing beam. The damage to the hatch of the helicopter caused by goods deflection is effectively solved.
Description
technical field [0001] The invention belongs to the field of helicopter hanging and dropping, and relates to a helicopter load transmission and anti-sway structure and a helicopter. Background technique [0002] Helicopter hanger delivery system hangs and transports goods because it does not require a special airport and has no restrictions on the volume and shape of the goods. It can quickly and flexibly transport goods, weapons and equipment, construction machinery, material supplies, emergency relief supplies, etc. It has incomparable advantages in road, railway, and fixed-wing aircraft transportation. In order to effectively reduce the weight of the body during the structural design of the medium-sized and heavy-duty helicopter hanging delivery system, the main load-bearing point will be designed on the base of the main gearbox. A helicopter hanging delivery system, the upper part of the cargo hook is connected to the lower end of the main gearbox through a sling, and th...
