Description of drawings
The aircraft deicing vehicle structural representation that has automatic leveling and anti-inclination function that Fig. 1 provides for the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the aircraft deicing vehicle that has automatic leveling and anti-inclination function that the utility model provides is elaborated.
As shown in Figure 1, the aircraft deicing vehicle that has automatic leveling and anti-inclination function that the utility model provides comprises as motion platform and has vehicle 1, liquid reserve tank, temperature booster, pipeline jetting system, three degree of freedom lifting mechanism 2, aloft work hurdle 3, operation hurdle leveling equipment, car body horizon sensor 4 and the computer control system 5 on chassis; Wherein liquid reserve tank, temperature booster and pipeline jetting system are installed on the chassis of vehicle 1; The lower end of three degree of freedom lifting mechanism 2 is installed in the postmedian on chassis by turntable 14, thereby can integral body rotate, it comprises the first and last end folding arm 6 in pivotally attached the 1st～3rd successively, 7,8 and two ends be installed in the 1st～the 3rd lifting hydraulic cylinder 9 on turntable 14 and the 1st folding arm the 6, the 1st folding arm 6 and the 2nd folding arm 7 and the 2nd folding arm 7 and the 3rd folding arm 8 respectively, 10,11; Aloft work hurdle 3 is installed in the end of the 3rd folding arm 11; Operation hurdle leveling equipment comprises the 1st and the 2nd leveling hydraulic actuating cylinder 12,13 that structure is identical; Wherein the two ends of the 1st leveling hydraulic actuating cylinder 12 are connected to the middle part of the 2nd folding arm 7 and the upper end of the 1st folding arm 6, the two ends of the 2nd leveling hydraulic actuating cylinder 13 then are connected on the end of the 3rd folding arm 8 and the aloft work hurdle 3 the outside face bottom near the 3rd folding arm 8, and two leveling hydraulic actuating cylinders 12,13 rodless cavity links to each other by hydraulic tubing 15, and rod chamber also links to each other by hydraulic tubing 15; Car body horizon sensor 4 is arranged on a side of vehicle 1; Computer control system is installed on the vehicle 1, is used to control the rotation of three degree of freedom lifting mechanism 2 and the action of the 1st and the 2nd leveling hydraulic actuating cylinder 12,13.
The the described the 1st and the 3rd folding arm 6,8 is a parallel four-bar linkage, and the 2nd folding arm 7 then is the mechanical rigid structure.
When the aircraft deicing vehicle that has automatic leveling and anti-inclination function that utilizes the utility model to provide when needs carries out the deicing operation, at first the staff enters into aloft work hurdle 3, and at the enterprising line operate of the guidance panel on aloft work hurdle 3, start the 1st lifting hydraulic cylinder 9 then and fold arm 6 and rise the 1st, starting the 2nd lifting hydraulic cylinder 10 afterwards rises the 2nd folding arm 7, starting the 3rd lifting hydraulic cylinder 11 at last rises the 3rd folding arm 8, arrive the deicing job position until aloft work hurdle 3, open spray gun then and can carry out the deicing operation.Because the 1st folding arm 6 is a parallel four-bar linkage, utilize its two groups of opposite side in deformation process to remain parallel principle the relative position of the 2nd folding arm 7 and the 3rd folding arm 8 is remained unchanged, and then the pose on aloft work hurdle 3 can change yet.In like manner, because the 3rd folding arm 8 also is a parallel four-bar linkage, therefore the motion of the 3rd folding arm 8 can not impact the pose on aloft work hurdle 3 yet.
When the center of gravity owing to the deviation of gravity center vehicle 1 of three degree of freedom lifting mechanism 2 makes vehicle 1 inclination of left and right directions occur, in case car body horizon sensor 4 detects degree of dip value of overstepping the extreme limit of vehicle 1, it will send signal to computer control system 5.Computer control system 5 is at first sent alerting signal after receiving this signal, controls turntable 14 simultaneously and is rotated, and overlaps with the center of gravity of vehicle 1 so that be installed in the center of gravity of the three degree of freedom lifting mechanism 2 on the turntable 14, and at this moment vehicle 1 just can recover normal condition.If when the upper end on aloft work hurdle 3 being turned forward because of the inclination of vehicle 1 or owing to second decline that folds arm 7, under the control of computer control system 5, at first the piston rod of the 1st leveling hydraulic actuating cylinder 12 is withdrawn, at this moment, the hydraulic oil that rodless cavity pumps from the 1st leveling hydraulic actuating cylinder 12 will enter in the rodless cavity of the 2nd leveling hydraulic actuating cylinder 13 by hydraulic tubing 15, thereby make the piston rod of the 2nd leveling hydraulic actuating cylinder 13 protruding, the result promotes aloft work hurdle 3 and is rotated along clockwise direction in vertical plane surface; Otherwise, if when the lower end on aloft work hurdle 3 being turned forward because of the inclination of vehicle 1 or owing to second rising that folds arm 7, the 2nd leveling hydraulic actuating cylinder 13 will drive aloft work hurdle 3 and be rotated in the counterclockwise direction in vertical plane surface, finally make aloft work hurdle 3 be returned to horizontality.
