Description

Technical Field

[0001] The invention belongs to the technical field of heavy-duty airdrop, in particular to a large-tonnage heavy-duty parachute dropping umbrella stand. Background Art

[0002] In the field of large-tonnage heavy-duty airdrop systems, the weight of the delivered objects is as high as 20 tons, and multiple large-area parachutes are required to ensure the stable descent of the delivered objects during the airdrop process. The working process of multiple large-area parachutes involves the problem of bundling and arranging them on the cargo platform, as well as the problem of parachute opening synchronization. The parachute rack can be used to bundle and arrange the main parachute system according to its requirements, ensuring the reliability of its parachute opening procedure and improving the parachute opening synchronization of the parachute system.

[0003] On the other hand, the dropped objects include a wide variety of products, such as ammunition boxes, vehicles, weapons and equipment, etc. For products such as ammunition boxes, they do not have the ability to provide a binding and layout interface for the main parachute system, and also require a parachute rack to place the parachute system.

[0004] The existing parachute racks of domestic airdrop systems cannot meet the requirements of large-tonnage airdrop systems. First, the existing parachute racks are fixed in shape and cannot be adjusted. The types of weapons, equipment and materials carried by large-tonnage airdrops are diverse, and the non-adjustable parachute racks will greatly reduce the loads that can be adapted to the cargo platform; second, the parachute placement position of the existing parachute racks is within the edge of the cargo platform. For airdrop systems with a small number of main parachutes, the parachute rack height can be increased to avoid interference with the airdrop load. However, large-tonnage airdrop systems have a large number of main parachutes, and the parachute rack height is relatively low, which cannot avoid interference with the airdrop load.

[0037] 5) The main body of the support frame is a left-right symmetrical part, which consists of a frame head (left-right symmetrical part), a horizontal tube, a lower frame sleeve (left-right symmetrical part), an oblique reinforcement tube, a vertical tube, a right threaded sleeve (25), and a rotary ear 1 (30). The horizontal tube (36) and the vertical tube (39) are respectively inserted into the corresponding horizontal connecting column and the vertical connecting column on the frame head (35) and connected by welding; the two ends of the oblique reinforcement tube (38) are respectively welded to the horizontal tube and the vertical tube; the lower frame sleeve (37) is welded to the connection position between the horizontal tube and the oblique reinforcement tube; the right threaded sleeve is welded to the inside of the vertical tube near the end, and the rotary ear 1 is screwed into the right threaded sleeve through a thread. See the schematic diagram of the main body of the support frame. Fig.10 .

[0038] The main installation process of the heavy-duty parachute stand is as follows:

[0039] 1) When installing, first connect the support frame body to the umbrella stand main part 1. Taking the right side as an example, insert the protruding cylinder at the lower end of the umbrella stand main part 1 into the hole at the upper end of the support frame body Y7, and lock it with the quick release pin 5. When installing, pay attention to the horizontal ears of the frame heads 35 on both sides facing each other, and then use M12×40 bolts, M12 nuts and Φ12 washers to connect the lower frame cover 37 and the right upper frame cover 23. See the schematic diagram of the connection between the support frame body Y7 and the umbrella stand main part 1. Fig.11 .

[0040] 2) After the support frame body is connected to the main part of the umbrella stand 1, connect the rotating ear 1 at the bottom of the support frame body 1 to the ear piece at the corner of the cargo platform and lock it with a quick release pin. Control the umbrella stand to make it stand upright, connect the pull rod 6 and the adjustment rod to the ear piece on the head of the support frame body 1, and lock it with a quick release pin. Fig.12 , Fig.13 .

[0041] 3) Connect the other end of the pull rod 6 and the other end of the adjustment rod to the connecting ear piece on the cargo platform respectively, and lock them with the quick release pin. Fig.14 .

[0042] Under the requirements of high / plain and different parachutes, the present invention controls the length of the parachute stand by adjusting the rod, so that the parachute stand can be adapted to the transport aircraft, and provides a placement space for the parachute system on the airdrop platform, thereby increasing the stability of the heavy parachute system during transportation and improving the synchronization of the parachute system opening.

[0043] The present invention is adapted to various transport aircraft by adjusting the length of the umbrella stand, the height of the umbrella stand and the longitudinal position relative to the cargo platform; and by adjusting the length of the umbrella stand, the height of the umbrella stand and the transverse position relative to the cargo platform, the installation position of the object delivery is avoided to ensure that the two do not interfere with each other.

[0044] The invention has been tested nearly 20 times on the ground and in the air. The test process is good, the strength meets the requirements, and all adjustable parts are adjusted smoothly without any faults such as poor movement and jamming, thus achieving the expected effect.
