Problems solved by technology

[0003] At present, the delivery of goods by helicopters is mainly carried out by hanging and landing. The goods are hung under the helicopter for transportation. After reaching the target point, the helicopter is controlled to descend vertically, so that the goods suspended below are landed, and then the unloading is completed. This method is only suitable For flat ground, and for complex terrain such as swamps, jungles, and islands, the helicopter is generally suspended at a low altitude of 10-30 meters, and then the cargo is directly dropped from the cabin to the ground. The hanging delivery of the helicopter requires the cooperation of the ground crew. One end of a series of slings and rope nets is connected to the belly of the helicopter through a hook, and the other end is fixed on the ground by the ground crew before unloading. This delivery method is more efficient. Low, and the helicopter needs to hover for a long time, during which the low-altitude air flow has a great impact on the hovering of the helicopter, and there is a big safety hazard

Embodiment

[0030] Such as figure 1 , figure 2 and image 3 As shown, the helicopter fixed-point and fixed-speed delivery device provided in this embodiment includes a pay-off reel 1 installed in the cabin, a continuous delivery device 4, a slideway 5, a cutting device 6, a cable drop belt 2 and a damping speed reduction mechanism 3 , the pay-off reel 1 is fixed on the floor surface in the cabin by the installation frame, and the rope drop belt 2 is selected as a synchronous belt, and one end thereof is fixed to the pay-off reel 1 and wound on the pay-off reel 1;

[0031] The damping deceleration mechanism 3 includes a synchronous wheel 301 correspondingly matched with the cable drop rope belt 2. The axis of the synchronous wheel 301 is equipped with a driving shaft 305 that runs through its two ends and is coaxially arranged. The two ends of the driving shaft 305 are symmetrically sleeved. There is a driving gear 306, the driving gear 306 is engaged with a driven gear 307, the driving...

Abstract

The invention discloses a helicopter fixed-point constant-speed delivery device. The helicopter fixed-point constant-speed delivery device comprises a paying-off winding drum, a cable descending ropebelt and a damping deceleration mechanism, wherein the paying-off winding drum is arranged in a cabin; one end of the cable descending rope belt is fixed onto the paying-off winding drum, and the other end of the cable descending rope belt is a free end; and the damping deceleration mechanism is arranged on the cable descending rope belt, and descends at a constant speed along the cable descendingrope belt after goods are lifted. By using a mode that the damping deceleration mechanism drives the goods to slowly descend together, the low-altitude fixed-point constant-speed delivery by a helicopter is realized; the delivery efficiency is high; the damage rate of the goods after the delivery is low; in addition, the helicopter fixed-point constant-speed delivery device is applicable to low-altitude delivery in various severe terrains; and the safety of low-altitude delivery by the helicopter is improved.

Description

technical field [0001] The invention belongs to the technical field of helicopter low-altitude delivery, and in particular relates to a fixed-point and fixed-speed delivery device for a helicopter. Background technique [0002] Helicopters can take off and land vertically, hover in the air, and can fly front and back, left and right, and at low altitudes. Therefore, helicopters have high military and civilian value. In the military field, it can be used for military transportation, base supply, ammunition delivery, etc.; in the civilian field, helicopters can be used for engineering construction, fire disaster relief, medical rescue, agriculture, forestry, animal husbandry, fishery, transportation, etc. [0003] At present, the delivery of goods by helicopter is mainly carried out by hanging and landing. The goods are hung under the helicopter for transportation. After reaching the target point, the helicopter is controlled to descend vertically, so that the goods suspended ...
