Abstract
The invention discloses a front undercarriage carrying trailer for a damaged aircraft. The front undercarriage carrying trailer comprises a frame, a damping support post outer barrel, a piston rod, a plurality of front wheels, a plurality of rear wheels and two rear wheel damping devices, wherein the frame is a flat plate; the upper end of the damping support post outer barrel is connected to the middle of the front end of the bottom surface of the frame; the front wheels are connected together through a front middle axle; the upper portion of the piston rod is positioned inside the damping support post outer barrel, and is connected with the damping support post outer barrel through a damper; the lower end of the piston rod is connected to the middle of a front middle axle; the rear wheels are divided into two groups, and each group is connected together through a rear middle axle; the upper ends of the two rear wheel damping devices are fixed on both sides of the back portion of the bottom surface of the frame respectively, and the lower ends of the two rear wheel damping devices are connected to the middle of a rear middle axle respectively. According to the front undercarriage carrying trailer, the front wheels are designed in the form of a front undercarriage of the aircraft, thereby allowing to direct tow by using a rod-free towing vehicle. Moreover, the carrying trailer has the advantages of small size, light weight, flexibility in operation and low cost.
Description
Technical field
The invention belongs to civil aviation equipment technology field, particularly relate to a kind of damaged aerocraft nose-gear moving trailer utilizing without the traction of bar tractor truck.
Background technology
Current damaged aerocraft moving trailer is used for airport emergency management and rescue as standard equipment more and more.For impaired or inoperable aerocraft, usually with tractor truck, draw the nose-gear moving trailer that is placed with above-mentioned aerocraft on it.But at present conventional nose-gear moving trailer is owing to not being similar to the wheel of aerocraft alighting gear, so can not be with drawing without bar tractor truck.Therefore need a kind of new nose-gear moving trailer to solve the problems referred to above.
Summary of the invention
In order to address the above problem.The object of this invention is to provide the enough nose-gear moving trailers without the traction of bar tractor truck of a kind of energy.
In order to achieve the above object, nose-gear moving trailer provided by the invention comprises vehicle frame, shock strut urceolus, piston rod, a plurality of front-wheel, a plurality of trailing wheel and two rear wheel damping devices; Wherein vehicle frame is tabular; The upper end of shock strut urceolus is connected to the bottom surface front center of vehicle frame; The anterior axis of a plurality of front-wheel utilizations links together; It is inner that the top of piston rod is positioned at shock strut urceolus, and be connected with shock strut urceolus by bumper, and the lower end of piston rod is connected to anterior axis middle part; A plurality of trailing wheels are divided into two groups, and every group is utilized respectively a rear portion axis to link together; The upper end of two rear wheel damping devices is separately fixed at the position, both sides, rear portion, bottom surface of vehicle frame, and lower end is connected to axis middle part, a rear portion.
Described vehicle frame 1 surface is provided with the attaching parts that can be connected with fuselage support platform, and aft end face is provided with hook.
Between described piston rod and urceolus, be also provided with angular transducer, angular transducer is electrically connected to the control setup on main landing gear moving trailer.
Damaged aerocraft nose-gear moving trailer provided by the invention is the form of aircraft nose-gear that its front-wheel is designed to, and therefore can use without bar tractor truck and directly draw.In addition, the angular transducer arranging between piston rod and shock strut urceolus can be delivered to main landing gear moving trailer by the angle of front-wheel, therefore can make main landing gear moving trailer wheel can adjust corresponding angle to complete whole turning.In addition, it is little, lightweight that this moving trailer also has volume, flexible operation and low cost and other advantages.
Accompanying drawing explanation
Fig. 1 is damaged aerocraft nose-gear moving trailer structural representation provided by the invention;
Fig. 2 is damaged aerocraft nose-gear moving trailer provided by the invention and trailer coupled condition schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, damaged aerocraft nose-gear moving trailer provided by the invention is described in detail.
As shown in Figure 1 and Figure 2, nose-gear moving trailer provided by the invention comprises vehicle frame 1, shock strut urceolus 2, piston rod 3, a plurality of front-wheel 4, a plurality of trailing wheel 5 and two rear wheel damping devices 6; Wherein vehicle frame 1 is tabular; The upper end of shock strut urceolus 2 is connected to the bottom surface front center of vehicle frame 1; A plurality of front-wheels 4 utilize anterior axis to link together; The top of piston rod 3 is positioned at shock strut urceolus 2 inside, and is connected with shock strut urceolus 2 by bumper, and the lower end of piston rod 3 is connected to anterior axis middle part; A plurality of trailing wheels 5 are divided into two groups, and every group is utilized respectively a rear portion axis to link together; The upper end of two rear wheel damping devices 6 is separately fixed at the position, both sides, rear portion, bottom surface of vehicle frame 1, and lower end is connected to axis middle part, a rear portion.
Described vehicle frame 1 surface is provided with the attaching parts 10 that can be connected with fuselage support platform 7, aft end face is provided with hook 11, can this nose-gear moving trailer be connected with two main landing gear moving trailers 9 by hook 11 and pipe link 8, to participate in the rescue to aerocraft simultaneously.
Between described piston rod 3 and urceolus 2, be also provided with angular transducer, angular transducer is electrically connected to the control setup on main landing gear moving trailer 9.
Now damaged aerocraft nose-gear moving trailer using method provided by the invention is described below: when needs are moved damaged aerocraft, first utilize crane by aerocraft lifting, then by this nose-gear moving trailer and two main landing gear moving trailers 9, by the hook 11 on vehicle frame 1 and pipe link 8, the mode with Fig. 2 links together.Then make nose-gear moving trailer move to aircraft fuselage below, afterwards the head of aerocraft is placed in fuselage support platform 7, two wings are placed in respectively in the support platform of two main landing gear moving trailers 9 simultaneously.Behind good aircraft position to be adjusted, use without the lifting clamp device of bar tractor truck a plurality of front-wheels 4 on nose-gear moving trailer are firmly held tightly and lifting, then draw nose-gear moving trailer and advance.When turning, angular transducer between piston rod 3 and shock strut urceolus 2 can pass to the control setup on main landing gear moving trailer 9 by the anglec of rotation of front-wheel 4, by this control setup, control the corresponding angle of wheel adjustment on main landing gear moving trailer 9, complete thus whole turning.
