Transmission system of carrier-based helicopter landing assisting device

Abstract

The invention discloses a transmission system of a carrier-based helicopter landing assisting device, and belongs to the field of mechanical equipment transmission. The transmission system comprises a hydraulic cylinder group which is fixed on a shell and is used for providing power for the whole system, four chain wheel winding groups which are coaxially and fixedly connected and then are fixed on the shell, two capturing beams which move on the track of the shell, two fixed pulley groups and two fixed pulleys which are fixedly arranged on the shell, two chains which are connected with the hydraulic cylinder group and the chain wheel winch group, and eight steel cables which are used for transmitting motion; the reciprocating motion of the cylinder barrel of the thin hydraulic cylinder is converted into the opposite and separated motion of the two capturing beams, so that the quick capturing and releasing of the carrier-based helicopter probe rod are realized; and after capturing succeeds, the probe rod is locked between the two capturing beams, the reciprocating motion of the cylinder barrel of the thick hydraulic cylinder controls the two interlocked capturing beams to transversely and synchronously move, and straightening of the helicopter is achieved in cooperation with the longitudinal motion of the whole landing assisting device. The system is simple in structure, small in occupied space, high in capturing reliability and convenient to operate and maintain.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment transmission systems, in particular to a transmission system of a landing aid device for a shipboard helicopter, which is used for capturing, releasing and aligning the shipboard helicopter. Background technique [0002] As an important maritime weapon and equipment, carrier-based helicopters are based on aircraft carriers or other ships and can perform various tasks such as anti-submarine, anti-ship, reconnaissance, search and rescue, transportation, amphibious assault, air early warning, mine warfare, and electronic warfare. , can effectively enhance the carrier's defense and landing capabilities, and expand the carrier's sphere of influence. However, due to the complex sea conditions, the ship is in a state of swaying and sinking, and it is very easy to slip or even overturn when the helicopter lands on the ship, causing a series of major accidents. In order to ensure that the hel...
