Abstract
A jet airport pavement sweeping vehicle is mainly composed of an aviation engine and a chassis, which is also provided with an extending spray tube. The extending spray tube is fixed on a connecting rod frame of a transition mechanism; the transition mechanism is fixed on the vehicle beam; a hydraulic actuator cylinder manipulation swing arm rod can drive the connecting rod frame and the extending spray tube to rotate. When the angle between the extending spray tube and the vehicle beam axis is zero degree, the spray tube is in parking state; when the angle reaches 95 degree, the spray tube and a main pray tube are in an incoordinate-section connection state. Part of the air stream sprayed by the main spray tube directly acts on the ground, while the other part of the air stream is sprayed out through the extending spray tube so as to enlarge the cleaning area. In order to prevent damage to the pavement caused by high-temperature fuel gas, the vehicle is also provided with a sprinkler system to lower the gas temperature.
Description
A kind of road-sweeper, particularly a kind of with aero-jet engine as cleaning power, and have the jet-propelled airfield pavement road-sweeper of spray cooling system and extendible nozzle.
At present, the cleaning of China's military, civilian airport runway mainly is to rely on aero-jet engine to be installed in the Jet snow-blowing vehicle that constitutes on the truck to finish.Jet pipe assembly behind the jet engine turbine is divided into two-way, and what place automobile side is the main jet pipe, places the secondary jet pipe that is at vehicle front place.There is a fixed angle on the spout axis and the ground of major and minor jet pipe.Because jet pipe fixed installation, when causing jet cleaning, can not show consideration for far and near regionally simultaneously, wasted a part of air-flow.In addition, because the gas flow temperature of jet engine ejection is very high, and spout is nearer from the road face, the runway road face of therefore easily burning.For addressing the above problem, Chinese patent ZL992101549 has provided a kind of with technical scheme that can change the little jet pipe of the angle of pitch of the terminal increase of main jet pipe, to reach blowing apart from the purpose of car body than dirty dirt in distant place or accumulated snow.Yet, because air-flow must have certain angle that good blowing effect just can be arranged with ground, and combustion gas from jet pipe ejection back the reason of diffusion rapidly, it is unsatisfactory that the territory, far field of this scheme purges effect.Simultaneously, this scheme is also very limited by the effect that sluice way introduction cold air reduces jet temperature.
The purpose of this utility model is to provide a kind of jet-propelled airfield pavement road-sweeper that an extendible nozzle is housed at aero-jet engine main injection jet end.Extendible nozzle is handled by hydraulic system, can rotate with main injection jet butt joint in 95 ° of scopes or separates.Jet-propelled airfield pavement road-sweeper of the present utility model also is provided with the spray cooling system to the cooling of jet engine high-temperature fuel gas simultaneously.
Airfield pavement road-sweeper of the present utility model is to have increased new technical scheme to realize on the Jet snow-blowing vehicle basis of prior art.Technical scheme is characterised in that has set up spray cooling system, hydraulic system, turnover mechanism, extendible nozzle and watch-dog.Extendible nozzle has one 0 °-95 ° angle of rotation.When angle of rotation was 0 °, the extension axis was parallel with the automobile chassis axis.When angle of rotation was 95 °, the extendible nozzle air inlet port docked with the engine main jet pipe puff prot, and the angle on extendible nozzle axis and ground is less than the angle on engine main jet pipe axis and ground.
Spray cooling system is made up of tracheae, water pipe, water tank, injector, fountain head and electromagnetic valve.Water pipe is connected with water tank.Tracheae is connected with the aero-engine collection chamber.The other end of water pipe, tracheae all is connected on the injector.Injector is connected on the fountain head.Fountain head places main jet pipe end.Electromagnetic valve places on the system pipeline.
Turnover mechanism is by upper ledge, lower frame, stile, rocking lever, connecting rod rest, and driven bridge, minor axis, major axis, rocker arm shaft, driven bridge axle, roller, swing link and link rod are formed.The lower frame middle part is fixed with a rocker arm shaft, and rocking lever is installed on the rocker arm shaft in center.One end of rocking lever has a bearing support, and the other end has a hinge and a roller.The bearing support of rocking lever and major axis lower end are hinged, and hinge and hydraulic system pressurized strut piston rod are hinged, fit in roller and swing link bottom surface.The swing link two ends are fixed on two stiles, and the middle part is fixed by link rod and automobile beam.Connecting rod rest and driven bridge all are flat-square shaped.A half elliptic breach is arranged on the connecting rod rest interarea, and breach is identical with extendible nozzle air inlet port cross section, and extendible nozzle air inlet port end is fixed on the half elliptic breach of connecting rod rest.Major axis and minor axis are separately fixed on the narrow vertical plane at connecting rod rest two ends, and axis is parallel with the stile axis.One end of the narrow vertical plane of driven bridge passes through two articulated minor axises of bearing support up and down, and the other end is welding driven bridge axle.Driven bridge axle two ends are hinged on the stile by two bearing supports on the stile.In the turnover mechanism limit switches and caging bolt are housed also.
The pressurized strut piston rod of hydraulic system drives rocking lever and rotates around rocker arm shaft, and the roller on the rocking lever has a movement in a curve track on the swing link bottom surface, and rocking lever drives the turnover mechanism kinematic.Rocker arm shaft, major axis, minor axis and driven bridge axle and rocking lever, connecting rod rest and follower link frame constitute quadric chain jointly.
Extendible nozzle is the body of semiellipse cylindricality, and the gas channel cross section is a half elliptic, and the extendible nozzle air inlet port is that unequal section docks with the oval spout of engine main jet pipe.
Jet-propelled airfield pavement road-sweeper of the present utility model, engine main jet pipe is the secondary relay-type, the air-flow of main jet pipe ejection, and a part is directly cleaned near field from the ejection of main jet pipe, another part cleans the territory, far field through the extendible nozzle ejection, has greatly expanded purging zone.When extendible nozzle is not worked,, by turnover mechanism extendible nozzle is placed the railway carriage bottom, so that do not influence this car cruising through hydraulic operation.For the high-temperature gas that prevents the aero-engine ejection damages runway road face, spray cooling system is sneaked into high-temperature fuel gas with water, to reduce the ground connection temperature of combustion gas.Jet-propelled airfield pavement road-sweeper of the present utility model is a kind of desirable military, civilian airfield runway road-sweeper.
