The invention discloses a quick-release pin and a disassembly and assembly method thereof. The quick-release pin comprises a pin body and a limiting column, and one end of the limiting column is connected with the pin body through a pin shaft. A limiting block is integrally formed on the pin body; the limiting column can rotate around the pin shaft till the axis of the limiting column is collinear with or perpendicular to the axis of the pin body. The disassembling and assembling method comprises the following steps that S1, the lifting lugs are placed at the positions of the mounting edges of the outer duct rear casing, and pin holes in the lifting lugs are aligned with mounting holes in the mounting edges; s2, the limiting column is rotated until the axis of the limiting column is collinear with the axis of the pin body, the quick-release pin is inserted into the mounting hole in the mounting edge from the pin hole of the lifting lug, and the limiting column extends out of the mounting hole in the mounting edge of the outer duct rear case; s3, the limiting column is rotated till the axis of the limiting column is perpendicular to the axis of the pin body, and installation and connection of the lifting lug and the outer culvert rear case are completed; and S4, when the lifting lug needs to be dismantled, the limiting column is rotated till the axis of the limiting column is collinear with the axis of the pin body, then the whole quick-release pin is pulled out, and the lifting lug can be dismantled.
本发明公开一种快卸销及其拆装方法。快卸销包括销体和限位柱,限位柱的一端与销体通过销轴连接;在销体上一体成型有限位块;限位柱可绕着销轴转动,限位柱可转动至其轴线与销体的轴线共线或垂直。拆装方法包括以下步骤:S1、将吊耳放置在外涵道后机匣的安装边位置处,使得吊耳上的销孔与安装边上的安装孔对齐;S2、将限位柱转动至其轴线与销体的轴线共线,将快卸销从吊耳的销孔插入至安装边上的安装孔内,且限位柱从外涵道后机匣安装边的安装孔中伸出;S3、将限位柱转动至其轴线与销体的轴线相垂直,完成吊耳与外涵后机匣的安装连接;S4、当需要拆除吊耳时,先限位柱转动至其轴线与销体的轴线共线,然后将整个快卸销拔出,即可拆除吊耳。
