Combined cable collecting and releasing aviation winch cable arrangement device

Abstract

The invention discloses a combined cable collecting and releasing aviation winch cable arrangement device capable of being used for collecting and releasing cable arrangement of variable-cable-diameter variable-cross-section combined cables. The combined cable collecting and releasing aviation winch cable arrangement device comprises a lead screw supporting structure, a lead screw drive mechanism,a cable guide mechanism and an active traction mechanism. A motor I drives a lead screw to rotate through chain transmission. The cable guide mechanism and a lead screw nut do reciprocating linear movement along the lead screw. By controlling the rotating speed ratio of a drum motor and the motor I, variable-diameter cable arrangement can be achieved. By means of independent chain belts, conveying chains can have large bending radii within limited arc sections, and a large amount of space is saved compared with conventional pulley cable guide. A righting frame is designed into a beak shape onthe basis of the collision mechanics principle, and a streamline body which inclines can be effectively overturned and righted and can smoothly pass the cable arrangement device. By means of the active traction mechanism, the active traction and looseness prevention functions can be achieved by changing the spring expansion and contraction quantity and the rotating speed of a motor II to adjust the friction force exerted by rollers on the combined cables. The whole cable arrangement device is small in weight, small in size and particularly suitable for being used on aviation winches.

Description

technical field [0001] The invention relates to a cable unwinding device, in particular to an aerial winch cable unwinding device for composite cable retraction, and belongs to the technical field of aerial hoisting and retrieving. Background technique [0002] The tow cable is an important part of the underwater towed detection system, which acts as a connection between the towed platform and the underwater towed body, is responsible for the transmission of signals and power, and bears the towing force. When towing at high speed, the circular cross-section cable vibrates strongly in the water, which has a great impact on the attitude of the towed body. In order to reduce the vibration of the towed cable, improve the towing environment of the towed body, and improve its attitude stability, hair is usually installed on the towed cable. and a streamlined body to form a combination cable with variable cable diameter and cross-section consisting of a round cable, a hair cable an...

Problems solved by technology

However, the helicopter platform has strict restrictions on the weight and size of the aviation winch, and the design concept of the conventional marine retractable system to solve the composite cable retractable cannot be used for reference. Therefore, it is necessary to develop a light weight, small volume, and effective Aviation winch cable unwinding device to solve the problem of composite cable retraction
