Summary of the invention
The purpose of this utility model is to design a kind of afterbody lifting mechanism of aircraft gulley emptier, enlarging the range of use of gulley emptier, and improves the stability of whole device.
Its main technical schemes be in outside frame, be provided with can lifting inner frame, the lower fulcrum of hoist cylinder is connected with the bottom of outside frame, the piston rod of hoist cylinder is connected with inner frame top, in inner frame, be provided with can lifting slide block, slide block utilizes driving band to be connected with the top of inner frame.
Sprocket wheel is installed on top at inner frame, and an end of driving band is connected with the top of hoist cylinder, and the other end is connected with slide block.
Inboard at outside frame is provided with chute, in the outside of inner frame roller is installed, and inner frame utilizes roller to embed chute, is installed in the outside frame.
Inboard at inner frame is provided with chute, in the outside of slide block roller is installed, and slide block utilizes roller to embed chute, is installed in the inner frame.
Outside frame is installed on the chassis of gulley emptier, connects workplatform and little foul water tank on slide block.
Afterbody pedal, step are set on workplatform, foul valve and dirt inlet are set on little foul water tank.
Big foul water tank is installed on the chassis, wheel is set below the chassis, operator's compartment is set, foul valve and water inlet and hydraulic efficiency pressure system are set, dirt inlet is set on the top of big foul water tank in the bottom of big foul water tank in the front portion on chassis.
The utility model has the advantages that because lifting frame has comprised little foul water tank, workplatform, make a cover mechanism have lifting platform and receive two kinds of functions of sewage, thereby both can be used for the sewage disposal of airliner, can be used for the sewage disposal of air minibus again, improve the range of use of whole device, made things convenient for the sewage disposal work of various passenger planes; Secondly, this device utilizes internal and external frame formula structure and cooperating of slide block to realize lifting, and texture ratio is more reasonable, and especially stability better.

The specific embodiment
As shown in the figure: in whole lifting frame 4, be provided with in the outside frame 18 can lifting inner frame 17, the lower fulcrum of hoist cylinder 19 is connected with the bottom of outside frame 18, the piston rod of hoist cylinder 19 is connected with inner frame 17 tops, in inner frame 17, be provided with can lifting slide block 20, slide block 20 utilizes driving band 16 to be connected with the top of inner frame 17.
Inboard at outside frame 18 is provided with chute, in the outside of inner frame 17 roller is installed, and inner frame 17 utilizes roller to embed chute, is installed in the outside frame 18.Under the effect of hoist cylinder, inner frame 17 utilize its roller can be in the inboard chutes that are provided with of outside frame 18 up-and-down movement.
Inboard at inner frame 17 is provided with chute, in the outside of slide block 20 roller is installed, and slide block 20 utilizes roller to embed chute, is installed in the inner frame 17.Among Fig. 1 23 is the crossbeam on outside frame 18 tops, and 15 among Fig. 3 is illuminating lamp.
Outside frame 18 is installed on the chassis 24 of gulley emptier, connects workplatform 11 and little foul water tank 6 on slide block 20.During the slide block up-and-down movement, can drive little foul water tank up-and-down movement, so that transport the sewage on large-scale or the air minibus.
Big foul water tank 2 is installed on chassis 24, wheel 25 is set below chassis 24,24 front portion is provided with operator's compartment 1 on the chassis, and foul valve 7 and water inlet 9 and hydraulic efficiency pressure system 8 are set in the bottom of big foul water tank 2, on the top of big foul water tank 2 dirt inlet 3 is set.Big foul water tank is used to handle the sewage of airliner.The front portion of big foul water tank 2 is a filtered water tank, and the rear portion is used to hold sewage, and filtered water tank is used for the clear water of use in the splendid attire supply aircraft toilet, and its rear portion is used to receive the dirt in the aircraft toilet.
