The specific embodiment
In order to make technical matters to be solved by this invention, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
A kind of catapult-launching gear provided by the invention, as illustrated in fig. 1 and 2, comprises four strip adapter plates (11 and 12), four sliding wheels (21 and 22) and a flexible pipe 30; Four adapter plates (11 and 12) are symmetrical arranged between two, are fixedly connected with respectively each other by screw 40 at two ends, and therefore, four adapter plates (11 and 12) need eight screws 40 to fixedly mount altogether.Four sliding wheels (21 and 22) are separately fixed between two upper mounting plates 11 and between two lower installation boards 12 by described screw 40, slide up and down symmetrical setting between wheel, and four sliding wheels (21 and 22) are between fixing upper mounting plate 11 and the screw of lower installation board 12; Described flexible pipe 30 is arranged in the middle of four sliding wheels (21 and 22), clamps mutually setting by sliding up and down wheel.Certainly between the each adapter plate of the present invention, be not limited to be fixedly connected with by screw, can also connect by other means, such as hinged etc.
Preferably, the preferred vertical section of the adapter plate of the present embodiment is " L " type, and entirety is similar to angle iron structure.The folding face of adapter plate is oppositely arranged, and is convenient to so mutual fixed installation, weight simultaneously that also can save adapter plate, so that cost-saving, and be convenient to processing.Certain adapter plate of the present invention also can be set to prismatic, and prismatic is comparatively solid, not fragile.Adapter plate is mainly the framework as whole catapult-launching gear, its structure and weight are directly connected to the effect of launching of catapult-launching gear, therefore, the structure and material of adapter plate is particularly important, it is that structure is through many experiments checking that the present invention selects " L " type, its design is relatively simple, easily processes and be convenient to fixedly mount.The simultaneously preferred light material of adapter plate, reduces the weight of whole catapult-launching gear.
Further, four sliding wheels are divided into one group between two by the present invention, comprises respectively sliding wheel 22 after one group of advancing slip driving wheel 21 and a group, and the distance in every group of sliding wheel between two sliding wheels regulates by the screw 40 of fixing described upper and lower two adapter plates.Advancing slip driving wheel 21 is for stepping up flexible pipe 30 in case leak-stopping gas and reduce and launch effect, and rear sliding wheel 22 is main stress point, and flexible pipe 30 deformed dilation after inflation can apply powerful application force to rapidly rear sliding wheel 22, and after promoting, sliding wheel moves forward.And in order to make the stressed effect of rear sliding wheel better obviously, the present invention regulates the distance of 22 of sliding wheels after two by screw 40, make the distance between rear sliding wheel be greater than the distance between advancing slip driving wheel, and then make between rear sliding wheel, to there is larger space, thereby make flexible pipe have larger extending space, to apply larger application force in rear sliding wheel.
Preferably, the diameter of described rear sliding wheel 22 is more than or equal to the diameter of advancing slip driving wheel 21, before and after making, between sliding wheel, forms certain differential seat angle as far as possible, further strengthens and launches effect.
Further, as shown in Figures 3 and 4, described flexible pipe 30 of the present invention comprises inner flexible tube 31 and outer flexible tube 32, between inner flexible tube 31 and outer flexible tube 32, is enclosed with several steel wires 33 along flexible pipe direction interval.Inner flexible tube 31 is as the use of inflation; outer flexible tube 32 shields; the degree of expansion of restrictions inner flexible tube 32; after inner flexible tube 31 inflations; outer flexible tube 32 can prevent inner flexible tube 31 over expansions and explosion, and therefore, inner flexible tube can be selected the inner tube of a tyre of motor tire; and outer flexible tube selects soft and powerful and durable material to make, such as rubber.It is also the effect that prevents inner flexible tube over expansion and sizing in order to play that steel wire is set between interior outer flexible tube, further to protect inner flexible tube.
Preferably, described outer flexible tube 32 is wound around inner flexible tube 31 by strip rubber tape and forms, and this design can make outer flexible tube have transverse shifting space, has better tension force, makes in inner flexible tube inflation or deflation course, and the contraction of outer flexible tube is more flexible.Further, be connected with a spring 34 in the steel cord end of inner flexible tube admission port end, and be connected with a strainer 35 with the steel cord end of inner flexible tube admission port opposite end, inner flexible tube admission port is arrow indication place in figure, spring 34 can increase the flexibility ratio of the longitudinal extension of flexible pipe, strainer 35, for fixing flexible pipe, prevents that flexible pipe from swinging in inflation or deflation course, and effect is launched in impact.Preferably, every steel wire is all connected with spring and/or strainer, flexible like this or tension effect is better.
Again as shown in Figure 2, catapult-launching gear of the present invention also comprises two vertical guide plates 60 that a base 50 arranges with vertical base 50, adapter plate is arranged between two guide plates 60, and two lower installation boards 12 connect described guide plate 60 by bearing 70, like this, flexible pipe inflation drives sliding wheel to move, and then drive adapter plate to move to it, be connected and be set to bearing between two adapter plates and guide plate, can realize the level and smooth movement of adapter plate, placed dragging track skew and reduce ejection speed.
Catapult-launching gear of the present invention can taking off for carrier-borne aircraft on aircraft carrier, the catapult-assisted take-off of unmanned plane etc., carrier-borne aircraft or unmanned plane etc. are connected to and on catapult-launching gear, realize catapult-assisted take-off, therefore, the connecting portion that connects carrier-borne aircraft or unmanned plane can be set on catapult-launching gear, connecting portion can be arranged on upper mounting plate, for fixing screw of sliding wheel etc., in flexible pipe, gas is high pressure air or steam, in use, enter hose system by pressurized air or vapor source conveying high-pressure air or steam, anticyclonic pressure forces flexible pipe deformed dilation, thereby bringing pressure to bear on sliding wheel makes it roll to it, and then carrier-borne aircraft or unmanned plane that band is dynamically connected slide forward fast, operation is launched in realization.
Certainly, in order to strengthen propelling thrust, reliability and comformability, in use, many flexible pipes can be installed, quantity be specifically installed and determine according to type size and weight, certainly, for single hose system, many flexible pipe application can reduce wear and increase available probability.
In a word, compared to existing ejector, Novel ejection device structure of the present invention is comparatively simple, is easy to manufacture the less for ease of maintenaince nursing of parts.More there is no straight deck requirement, can use any curved surface.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
