Abstract

The invention provides a hinge mechanism for opening a cabin door in parallel. The hinge mechanism comprises a hinge rocker arm (4), a pneumatic actuating cylinder (3), a variable damping hydraulic buffer (8), a main chain wheel I (1), a main chain wheel II (6), an idle wheel I (5), an idle wheel II (7) and a chain (2), wherein the main chain wheel II (6) is connected in a spline fit manner with the supporting seat of the hinge rocker arm (4) on an aircraft body; the supporting seat of the hinge rocker arm (4) is fixedly mounted on the aircraft body; the cabin door of the aircraft body is connected with the hinge rocker arm (4) through a rotating shaft; the hinge rocker arm (4) can move around the rotating shaft; the main chain wheel I (1) is connected in a spline fit manner with the rotating shaft on the hinge rocker arm (4) together; the idle wheel I (5) and the idle wheel II (7) are arranged on the hinge rocker arm (4), so that the running direction of the chain (2) can be matched with the hinge rocker arm (4); the chain (2) is used for encircling the two main chain wheels and the two idle wheels on the hinge rocker arm (4). The hinge mechanism can be conveniently operated by an operator, and the occupied spaces in and outside a cabin can be relatively small when the cabin door is opened or closed.

Description

A kind of linkage making hatch door parallel opening
Technical field
The invention belongs to aviation field, relate to a kind of mechanism making hatch door parallel opening.
Background technology
Domestic Aircraft hatch door opening technology mainly contains outwards to rotate up and opens and be outwards flipped open forward.Outwards rotate up to open and generally do power source by motor or hydraulic pressure, be manually difficult to realize opening; Outwards be flipped open forward utilization linkage, and processing is complicated with assembling, and human users comparatively not easily.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of linkage making hatch door parallel opening, solves Domestic Aircraft hatch door and opens the problem that only mode has flipped form.
The present invention is realized by following technical measures: a kind of linkage making hatch door parallel opening, comprising: hinge Rocker arm 4, pneumatic cylinders 3, variable damping force hydraulic snubber 8, head sprocket I1/II6, idle pulley I5/II7 and chain 2;
Head sprocket II6 connects together with the hinge Rocker arm 4 supporting seat spline fitted on airframe, and hinge Rocker arm 4 supporting seat is mounted on airframe; Aircraft door is connected by axis of rotation with hinge Rocker arm 4, and hinge Rocker arm 4 can move around axis of rotation, is connected together by head sprocket I1 by spline fitted with the axis of rotation on hinge Rocker arm 4; Idle pulley I5/II7 is arranged on hinge Rocker arm 4 and chain operation direction and hinge Rocker arm 4 is fitted; With chain 2 around the head sprocket of 2 on hinge Rocker arm 4 and 2 idle pulleys.
Article two, the junction of chain 2 arranges pneumatic cylinders 3 and mutative damp snubber 8 respectively.
Beneficial effect of the present invention:
Utilize the parallel opening hinge means of 1 hinge rocking arm, 2 head sprockets, 2 fall wheel and chain compositions, hatch door outwards moves in parallel forward when can be made to open, this device is simple and reliable, size is little, compact conformation, for aircraft door outwards parallel opening forward, this kind of opening ways facilitates human users, and take when On/Off out of my cabin in cabin space less.
Pneumatic cylinders, snubber and high-pressure gas circuit design of system integration are opened for hatch door automatic emergency simultaneously and power is provided.And coordinate parallel opening mechanism by quick for hatch door emergency opening.

Detailed description of the invention
Below in conjunction with accompanying drawing and example, the invention will be further described:
As shown in Figures 1 to 5, a kind of linkage making hatch door parallel opening, comprising: hinge Rocker arm 4, pneumatic cylinders 3, variable damping force hydraulic snubber 8, head sprocket I1/II6, idle pulley I5/II7 and chain 2;
Head sprocket II6 connects together with the hinge Rocker arm 4 supporting seat spline fitted on airframe, and hinge Rocker arm 4 supporting seat is mounted on airframe; Aircraft door is connected by axis of rotation with hinge Rocker arm 4, and hinge Rocker arm 4 can move around axis of rotation, is connected together by head sprocket I1 by spline fitted with the axis of rotation on hinge Rocker arm 4; Idle pulley I5/II7 is arranged on hinge Rocker arm 4 and chain operation direction and hinge Rocker arm 4 is fitted; With chain 2 around the head sprocket of 2 on hinge Rocker arm 4 and 2 idle pulleys.
Article two, the junction of chain 2 arranges pneumatic cylinders 3 and mutative damp snubber 8 respectively.
During manually opened hatch door, chain 2 rotates, and head sprocket I1 is owing to assembling with hinge Rocker arm 4 supporting seat is fixing, and opposite from hinge Rocker arm 4 supporting seat and relatively airframe do not have rotary motion, then hinge Rocker arm 4 rotates relative to airframe; Axis of rotation on head sprocket II6 and hinge Rocker arm 4 is fixing to be assembled, relative aircraft door does not have rotary motion, then hinge Rocker arm 4 be diversion cabin door axis of rotation rotate, because head sprocket I1 is identical with head sprocket II6 size diameter, the be diversion axis of rotation of cabin door of the hinge supporting seat rotational angle of hinge arms on fuselage and hinge rocking arm rotates equal, therefore aircraft door rotates with airframe keeping parallelism in opening process.
Hatch door parallel opening linkage has emergency rescuing system (comprising pneumatic cylinders 3, variable damping force hydraulic snubber 8) simultaneously.Aircraft run into emergency need emergency opening hatch door time, chain 2 motion can be driven to realize landing gate emergency opening to pneumatic cylinders 3 inflation by providing high-pressure air source for oneself, steady when simultaneously ensureing landing gate emergency opening by mutative damp snubber 8, reduces to impact.This system provides power by providing high-pressure air source for oneself, safe and reliable, economic environmental protection.
