The invention discloses a dual-channel steel rope overrun mechanism and an aircraft landing gear hatch with the same. The dual-channel steel rope overrun mechanism comprises a bracket, a splined shaft, a first fan-shaped assembly, a second fan-shaped assembly, a first steel rope, a second steel rope, a lever, a first pre-tightening torsional spring, a second pre-tightening torsional spring and a third pre-tightening torsional spring, wherein the bracket comprises a connecting part, a first cylinder shaft and a second cylinder shaft; the splined shaft is arranged in a manner of penetrating through the first cylinder shaft and the second cylinder shaft; the first fan-shaped assembly is arranged on the first cylinder shaft; the second fan-shaped assembly is arranged on the second cylinder shaft; one end of the first steel rope is arranged on the first fan-shaped assembly; one end of the second steel rope is arranged on the second fan-shaped assembly; the lever is arranged between the first fan-shaped assembly and the second fan-shaped assembly, is connected with the splined shaft, and is provided with a first boss and a second boss; the first pre-tightening torsional spring is arranged on the first cylinder shaft or the splined shaft; the second pre-tightening torsional spring is arranged on the first cylinder shaft or the splined shaft; and the third pre-tightening torsional spring is arranged on the second cylinder shaft or the splined shaft. The dual-channel steel rope overrun mechanism disclosed by the invention is reasonable in structural configuration and convenient to mount; and the problem that a ground handle and an emergency handle in a cabin are in mutual non-interference is solved.
Description
technical field [0001] The invention relates to the technical field of aircraft structures, in particular to a double-channel steel cable mechanism and an aircraft landing gear hatch provided therewith. Background technique [0002] For products with only one external control structure, it needs to be driven by a set of mechanisms and using two different control modes, which puts higher requirements on the cable control mechanism. The two manipulation modes correspond to two different cable paths, and the manipulation of one mode has no influence on the mechanism of the other cable path. [0003] In general, when two different cable paths are used to complete the same manipulation task of the same product, it is often required that the driven product has two independent mechanical interfaces, which are connected to two cable systems to achieve two different operations. A cable-driven approach to task realization. For products with compact and complex structures, it is ofte...
