Aircraft rescue program-controlled triangle jack

Abstract

The invention provides an aircraft rescue program control triangle jack which is characterized by comprising three oil cylinders, a mobile tray, a mushroom jacking head, a retraction wire rope and a hydraulic capstan box. The upper ends of the three oil cylinders are respectively connected with the mushroom jacking head. The lower ends of the three oil cylinders are respectively connected with the mobile tray. The hydraulic capstan box is arranged in the center of the mobile tray and connected with the mushroom jacking head through the retraction wire rope. The three oil cylinders are simultaneously connected with a jacking control device for controlling the jacking path of the aircraft rescue program control triangle jack. Lifting type rollers are further arranged on the mobile tray. The aircraft rescue program control triangle jack has the advantage of being suitable for large-aircraft rescue.

Description

technical field [0001] The invention belongs to the technical field of aircraft rescue, and in particular relates to a program-controlled triangular jack for aircraft rescue. Background technique [0002] At present, after an aircraft loses its normal attitude due to a tire blowout or damage to the landing gear, the aircraft is generally lifted to the target altitude by using aircraft rescue jacking airbags or special aircraft spreaders. Due to the low efficiency of the rescue work due to the working principles of the two types of equipment, which affects the speed of rescue, and the general skin pressure bearing capacity of the aircraft is low, the above two methods often cause secondary damage to the aircraft. [0003] Rescue using aircraft jacking airbags: placing the airbags under the top of the aircraft and inflating them to lift the aircraft. [0004] First of all, due to the low pressure bearing capacity of the aircraft skin, in order to achieve sufficient jacking fo...

AI Technical Summary

Problems solved by technology

Due to the low pressure bearing capacity of the skin of the aircraft, it often causes damage to the skin to varying degrees in actual use; secondly, due to the heavy weight of the aircraft, especially the large aircraft, the total height and the large footprint, it must be equipped with a large-tonnage, long-arm crane for lifting , the whole set of lifting equipment is expensive; moreover, due to the softness of the crane's steel cables and spreaders, the attitude of the aircraft after lifting is often not ideal, and other means must be used to further adjust and stabilize its attitude, and the efficiency of the rescue process is low.
