Abstract
The present invention relates to a kind of aircraft shipping hatch door Tiebar structures, belong to technical field of aircraft structure design.Since hatch door assembly precision is inadequate and aircraft big opening region insufficient rigidity, it is inconsistent to will cause hatch door movement two sides.Tiebar structure of the present invention includes support, pulley base, pulley, T-type block, bar body, lower contact, limited block etc.；Support is hingedly installed on airframe at one end, in the other end by the limited block gap constraint on body, support is rotated in very little angular range；Pulley base is installed on support, and bar body passes through the notch that pulley base and support are formed, with pulley contact；Pull rod is connected by undersetting with hatch door.Overcome the problem that hydraulic actuator motion positions are not accurate enough, reliability is not high；By setting rotary structure for drag link bearing, pull rod is set to carry out angle compensation during hatch door is in either on or off, overcome hatch door deflects and move imbalance problem, enables pull rod is smooth to slide.
Description
Technical field
The present invention relates to a kind of aircraft shipping hatch door Tiebar structures, belong to technical field of aircraft structure design.
Background technique
In carrier at home and abroad, airplane cargo doors form mostly uses greatly the two-door structure opened up and down, cargo hold
Front door is driven by hydraulic actuator and is opened downwards, is closed upwards；Awing, cargo hold front door generally can be empty as aircraft
Drop ramp is thrown, is unfolded into the channel of personnel's disengaging, handling goods on the ground；Therefore airborne function is dropped in order to meet,
It must be provided with specialized structure to position after front door is opened for bearing, and bear shipping when dropping airborne and handling goods and carry
Lotus keeps hatch door to stablize, and avoids the reliability deficiency problem that hatch door is only driven and positioned by hydraulic actuator；Additionally, due to
Hatch door assembly precision not enough and aircraft big opening region insufficient rigidity, will cause hatch door movement two sides it is inconsistent, need to pass through machine
Structure setting is overcome, and when hatch door has certain beat or side-to-side movement imbalance, is still able to maintain two lateral balance of hatch door, is prevented from making
Hatch door bears load when dropping airborne and shipping and unevenly causes local failure.
Summary of the invention
The present invention provides a kind of aircraft shipping hatch door Tiebar structures, can effectively bear the shipping load of hatch door, and right
Hatch door plays the role of positioning and stable equilibrium, improves the reliability of hatch door shipping function.
The present invention devises a kind of machine shipping hatch door Tiebar structure, for using when aircraft door air-drop, airborne or shipping.
In shipping hatch door latter end two sides mounted in pairs, Tiebar structure by support, pulley base, pulley, T-type block, bar body, under connect
Head, limited block composition；Support is hingedly installed on airframe at one end, in the other end by the limited block gap constraint on body,
Support is rotated in very little angular range；Pulley base is installed on support, and bar body passes through pulley base and support
The notch of formation, with pulley contact；Pull rod is connected by undersetting with hatch door.Pull rod is worn during hatch door either on or off in this way
It crosses support to slide up and down with pulley base center notch, pull rod top is connected with T-type block, is opened to certain position downwards in hatch door
Afterwards, T-type block and pulley base upper contact, pull rod stop motion play positioning action to limit the open position of hatch door,
When carrying out dropping airborne shipping function at this time, pull rod plays the role of suspension.
The utility model has the advantages that shipping hatch door Tiebar structure is positioned as purely mechanic limit to the suspension of shipping hatch door, overcome hydraulic
The problem that pressurized strut motion positions are not accurate enough, reliability is not high；By setting rotary structure for drag link bearing, make pull rod
Angle compensation is carried out during hatch door is in either on or off, overcome hatch door deflects and move imbalance problem, makes pull rod
It smooth can slide；It can make hatch door being evenly distributed when bearing the load such as shipping after unlatching by the setting of pull rod, have
Effect avoids part from bearing the excessive caused hatch door of load or housing construction destruction.
Detailed description of the invention
Fig. 1 is drag link mechanism interarea figure of the present invention；
Fig. 2 is Tiebar structure left view of the present invention.
Specific embodiment
The present invention is described in further detail with specific embodiment with reference to the accompanying drawing:
Tiebar structure includes support 4, pulley base 2, pulley 3, T-type block 1, bar body 5, hatch door connector 6 and limited block 7
Deng.The support 4 of Tiebar structure is hingedly installed on airframe 8 at one end, and the other end is by 7 gap of limited block on airframe 8
Constraint, support 4 can rotate within the scope of 3 °.5 lower part of bar body is connected by hatch door connector 6 with 9 end of hatch door, is used simultaneously
A pair of of Tiebar structure.Pulley base 2 is installed on support 4, and bar body 5 passes through the notch of pulley base 2 and support 4, bar portion and cunning
3 contact of wheel；Gap of the bar body 5 during 9 either on or off of hatch door between notch and idler wheel 3 slides up and down；Pull rod sheet
5 top of body is connected with T-type block 1, and after hatch door 9 reaches opening in place, T-type block 1 is contacted with 2 upper surface of pulley base, realizes limit
Position is acted on carrying.
