Air drop automatic energy-absorbing vibration absorption flat-bed of heavy device

Abstract

The invention provides a heavy equipment airdrop self-suction damping cargo platform (1), and relates to airdrop equipment design technique. The heavy equipment airdrop self-suction damping cargo platform is characterized in that the lower bottom surface of the cargo platform is connected with a releasing soleplate (8) by a compression spring (11); the cargo platform is also provided with two sets of releasing locks which comprise an unlocking sliding block (2) and a releasing sliding block (3) which is provided with a lock tongue (4); the lock tongue extends out by passing through the side surface of the cargo platform; a reverse pushing spring (12) is arranged between the releasing sliding block (3) and the internal wall of the lock chamber; the cargo platform is provided with a locking guiding torsion spring component which comprises a torsion spring (6) with two ends bearing the force along the same direction; one end of the torsion spring is provided with a releasing rod (5) and the other end thereof is provided with a guiding rod (10); the releasing rod (5) is restricted or released by the lock tongue; the guiding rod (10) is matched with a guiding trough (9) which is arranged on the releasing soleplate (8) so as to limit the position. The heavy equipment airdrop self-suction damping cargo platform has the advantages of simple structure, and better damping and anti-vibration effect.

Description

technical field [0001] The air-drop self-absorbing and vibration-reducing freight platform for heavy equipment of the present invention relates to the design technology of air-dropped heavy equipment or material air-drop cargo platform for airborne operations or rescue and disaster relief, and the automatic energy-absorbing and vibration-reduction technology for heavy equipment or material air-drop cargo platform landing. Background technique [0002] The heavy equipment or materials needed for airborne operations or emergency rescue and disaster relief are bulky, heavy and limited by the special space-time and battlefield environment. They are delivered or supplied by reloading airdrops. At present, domestic airdrops for heavy equipment use a single or multiple 760m2 large parachutes as aerodynamic reducers, and 3-10 tons of equipment or materials can be airdropped on a 4-meter or 6-meter airdrop cargo platform. Airbags with complex structures and inconvenient installation ...

AI Technical Summary

Problems solved by technology

At present, domestic airdrops for heavy equipment use a single or multiple 760m2 large parachutes as aerodynamic reducers, and 3-10 tons of equipment or materials can be airdropped on a 4-meter or 6-meter airdrop cargo platform. Airbags with complex structures and inconvenient installation are used as energy-absorbing and shock-absorbing devices. The landing speed is generally 6-8m / s. They have the advantages of large umbrella shape and difficult matching, complicated parachute opening procedures, low landing speed, long time in the air, and heavy system weight. Disadvantages such as poor buffering effect
