Description
Technical field
The utility model relates to a kind of arrester hook deck-folding mechanism, belongs to aircraft manufacturing technical field.
Background technology
In order to reduce aircraft landing (warship) ground run distance, aircraft can adopt arrester hook device to realize short distance and block and stop, and catches on check cable when landing (warship).Tradition arrester hook system usually by fixed rotating shaft bearing, fixed rotating shaft, pressurized strut, expansion link, block hook joint head, arrester hook, fixed rotating shaft form, the direct push-and-pull arrester hook of its hydraulic actuation mechanism rotates around fixed rotating shaft, control packing up and putting down of arrester hook, pressurized strut has horizontal positioned and vertical placement two kinds, because pressurized strut power and the transmission arm of force, collapsing length etc. are inversely proportional to, the weight of pressurized strut is directly proportional to power, collapsing length, is difficult to the weight alleviating pressurized strut and expansion link.Can produce a very large impact load catch on the check cable on landing runway when arrester hook after, directly be passed to hydraulic actuator, require that pressurized strut has larger load-carrying capacity, usually adopt high strength steel and start barrel is thicker, structural weight is large.
Summary of the invention
In order to overcome above-mentioned defect, the purpose of this utility model is to provide a kind of arrester hook deck-folding mechanism, the basis of traditional arrester hook system adds a set of connecting rod mechanism, pressurized strut power stage is made to be passed to arrester hook via connecting rod mechanism, realize arrester hook steadily, failure-free folding and unfolding, and relieve the inverse relation of pressurized strut power and the transmission arm of force, collapsing length, actv. reduces power demand and the collapsing length of hydraulic actuator.The impact load that during landing (warship), arrester hook bears is diffused on housing construction by connecting rod mechanism, avoids pressurized strut to bear excessive impact load, and actv. reduces the requirement of strength of pressurized strut, expendable weight.
To achieve these goals, the utility model adopts following technical scheme:
A kind of arrester hook deck-folding mechanism, it comprises connecting rod I, top sub, fixed rotating shaft I, shaft seating, fixed rotating shaft II, pressurized strut, expansion link, connecting rod II, connecting rod III, fixed rotating shaft III, connecting rod IV, body surface, arrester hook, fixed rotating shaft IV;
The interconnected relationship of these compositions is: the fixed end of pressurized strut pressurized strut is fixedly connected on fixed rotating shaft II, fixed rotating shaft II is fixed on shaft seating, expansion link expansion link is hinged through the hinge to the top sub of connecting rod I, connecting rod connecting rod I one end is connected on fixed rotating shaft I, fixed rotating shaft I is fixed on shaft seating, and pressurized strut and connecting rod I form angle;
Connecting rod I other end is connected with connecting rod II one end by hinge, connecting rod II other end and connecting rod III free end chain connection, and the other end of connecting rod III is connected on fixed rotating shaft III, and fixed rotating shaft III is fixed on shaft seating;
Connecting rod IV one end is connected to connecting rod III underneath hinges joint along with fixed rotating shaft III and makes translational rotation movement, and connecting rod IV other end is connected on arrester hook upper hinge joint;
Arrester hook one end is connected to fixed rotating shaft IV, and fixed rotating shaft IV is fixed on shaft seating.
Pressurized strut, expansion link are through hydraulic-driven, expansion link stretches out or regains from pressurized strut, promote connecting rod I to rotate around fixed rotating shaft I hour hands, drivening rod II translation planar adds rotation, drivening rod III is around fixed rotating shaft III left-hand revolution, drivening rod IV translation planar adds rotation, thus puts down arrester hook.When connecting rod I and connecting rod II on the same line time, arrester hook puts down and puts in place, and now connecting rod I, connecting rod II, connecting rod III form triangle force transmission mechanism and the moment that arrester hook produces be diffused on housing construction.
The utility model has the following advantages:
By analysis and test show, transmission device of the present utility model can realize the function that arrester hook puts down and receive by pulsation-free, and mechanism is reliable, and the start distance that pressurized strut can be shorter realizes the longer arm of force.Simultaneously, when arrester hook is lowered into control position, connecting rod I 2-1.1, connecting rod II 2-6, connecting rod III 2-7 and carrier-borne aircraft fixed sturcture form triangle load-carrying construction, pulling force aircraft landing being blocked generation is directly diffused on aircraft body structure by connecting rod mechanism, reduces the requirement of strength to pressurized strut.

Fig. 2 is for being the utility model down state structural representation (being carrier-borne aircraft heading on the left of accompanying drawing).
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail:
A kind of arrester hook deck-folding mechanism, it comprises connecting rod I 2-1.1, top sub 2-1.2, fixed rotating shaft I 2-2, shaft seating 2-3, fixed rotating shaft II 2-4, pressurized strut 2-5.1, expansion link 2-5.2, connecting rod II 2-6, connecting rod III 2-7, fixed rotating shaft III 2-8, connecting rod IV 2-9, body surface 2-10, arrester hook 2-11, fixed rotating shaft IV 2-12;
The interconnected relationship of these compositions is: the fixed end of pressurized strut pressurized strut 2-5.1 is fixedly connected on fixed rotating shaft II 2-4, fixed rotating shaft II 2-4 is fixed on shaft seating 2-3, expansion link expansion link 2-5.2 is hinged through the hinge to the top sub 2-1.2 of connecting rod I 2-1.1, connecting rod connecting rod I 2-1.1 one end is connected on fixed rotating shaft I 2-2, fixed rotating shaft I 2-2 is fixed on shaft seating 2-3, and pressurized strut 2-5.1 and connecting rod I 2-1.1 forms angle;
