Embodiment Construction

[0020] Below in conjunction with accompanying drawing the present invention is described in further detail, please refer to Figure 1 to Figure 3 .

[0021] Such as figure 1 As shown, it is a schematic diagram of the gate lock mechanism of the traditional aircraft cargo bridge. The traditional cargo bridge gate lock mechanism is driven by the cylinder to drive the triangular rocker-pull rod-triangular rocker-pull rod, and finally to the transfer form of the lock hook. Different lock hooks The transmission path is slightly different, so some lock hooks have the problem of large cumulative clearance value. At the same time, the traditional cargo bridge door lock mechanism has a series of problems such as large number of structural parts, complicated transmission path, and poor interchangeability.

[0022] Such as figure 2 As shown, it is a structural schematic diagram of the present invention, an aircraft cargo bridge door lock mechanism, including a lock assembly 1 and an ac...

Abstract

The invention belongs to the field of aircraft structure control and relates to an airplane cargo bridge door locking mechanism which comprises lock assemblies and an actuator cylinder used as a drive unit and also comprises a torque mechanism. The actuator cylinder drives the torque mechanism to rotate. The torque mechanism is connected with several sleeve lock assemblies through bearings. Through the actuator cylinder, an actuator cylinder rocking arm, torque tubes, latch hook pull bars, a transmission support and latch hooks, locking and unlocking functions of the latch hooks are realized, and the structural style of an original airplane cargo bridge door locking mechanism is changed. The airplane cargo bridge door locking mechanism provided by the invention has a concise structure, is convenient to install and adjust, is harmonious and consistent in folding and unfolding, is safe and reliable, and is a novel practical cargo bridge door locking mechanism. The airplane cargo bridge door locking mechanism provided by the invention has advantages of few components, high interchangeability and reliable connection, and adjustment processes are minimized, and adjustment cycle is shortened. According to the invention, transmission movement path of part of the latch hooks is shortened, and accumulated clearance value caused by long transfer path is reduced. Thus, clearance oversize problem in the X direction and Y direction of the cargo bridge door is solved.

Description

technical field [0001] The invention belongs to the field of aircraft structure control and relates to a door lock mechanism of an aircraft cargo bridge. Background technique [0002] In the adjustment of the cargo bridge gate of a medium-sized medium-range transport aircraft, the following problems have always existed: [0003] 1. The adjustment cycle is long. It takes 20 days if the adjustment is smooth, and up to 40 days if the adjustment is not smooth. [0004] 2. There are many procedures for adjustment and arrangement. The adjustment process of the cargo bridge gate is generally three steps, which are the adjustment of the cargo bridge gate before the airtightness, the adjustment of the cargo bridge gate before the airtightness for the second time, and the adjustment of the cargo bridge gate after the flight. Under smooth conditions, the process can reach up to five. [0005] 3. It takes up a lot of aircraft production cycle. The cargo bridge gate of my country's ...
