The utility model content:
The purpose of the utility model is in order to overcome above deficiency, to provide a kind of in light weight, not long-pending little, being convenient to store and parking and carry transhipment, transportation, the telescopic aircraft draw gear of meeting consumers' demand.
The purpose of the utility model realizes like this:
The telescopic aircraft draw gear of the utility model; Comprise the main body pipe; Be arranged in main body pipe front and back ends and an end stretch into main body the pipe flexible and draw that protracts that can captive joint with the main body pipe through hinged clamping plate of main body pipe, back telescopic pipe relatively respectively; The draw front end that protracts is equipped with the drawing head of the steel rope support that contains rotation and can fix; The steel wire rope orientation pulley is contained on the main body pipe, is through the guide part that passes on the steel rope support at the steel rope two ends on the steel wire rope orientation pulley and is connected with aircraft aft engine wheel, and the main wheel support of main wheel is housed on the main body pipe; Be hinged on the main body pipe by cylinder block one end of manual pump control; It is hinged that piston rod stretches out an end and the main wheel support upper end of cylinder body, and the rear wheel support of band trailing wheel is being housed on the telescopic pipe of back, and forward and backward telescopic pipe can be realized length variations to the intermediate host pipe is flexible in 480mm～9600mm scope; Rotatable 90 ° of steel rope support; Can in 480mm～9600mm scope, realize wide variety, shake fuel priming pump, the main wheel support produces rotation under the effect of oil cylinder piston bar; Can in 560mm～1100mm scope, realize height change; Adopt hinge clamping plate (also cry and hold clip tightly) when the aircraft draw gear is worked, make the telescopic pipe at two ends and middle main body pipe become a rigid body, prevent that string is moving each other.
Above-mentioned steel rope support base plate is hinged on the indexing head center shaft and can be fixed on the drawing head center shaft through connecting element.
One end is arranged through hinge pivotally attached train wheel bridge, lower plate in the above-mentioned hinged clamping plate; Be hinged with movable bolt on the other end of lower plate; The position of relative movable bolt has movable bolt to cross groove on the other end of train wheel bridge; Movable bolt one end passes movable bolt and crosses groove and nut and cooperate the upper and lower clamping plate other end is connected, and when train wheel bridge unclamped, the two ends expansion link shrank along draw gear main body bar; This moment, draw gear was lacked ≯ 5 m most, can avoid the expansion link slight deformation and the situation that can't stretch.
Above-mentioned forward and backward telescopic pipe stretches on the other end in the main body pipe has safety screen, safety.
During the utility model work; Make forward and backward telescopic pipe and intermediate host pipe become a rigid body with the quick elongation of forward and backward telescopic pipe and with the hinge clamping plate; The rotatable wire rope support shakes manual pump to control position, makes the main wheel support rotate to desired height; Drawing head is installed on the undercarriage, and the steel rope two ends are fixed on the aircraft aft engine wheel just can.
The utility model is in light weight, and volume is little, and is fast flexible, easy to operate, and do not have loose pieces, and integral body is convenient to store and carry transhipment, practices thrift transhipment floor area ≮ 40%, safety.
