Abstract
A jack for airplane wheel shaft belongs to hydraulic jacks on the basis of a base, an oil cylinder fixed to the base, an adjustable oil cylinder, a piston, and a regulating screw nose plugged in the piston orderly sheathed in the oil cylinder, an oil tank in the middle part of the base, a pressure oil pump and a low-voltage oil pump fixed on the rear part of the base, a head, and a lever. A lift devices composed of two stand sleeve tubes and a U type handle are fixed between the oil cylinder and the oil tank, enabling the jack to be more convenient in use and more flexible to move.
Description
The utility model belongs to the hydraulic jack class
Existing aircraft wheel shaft jack is by the telescopic oil cylinder and the piston of suit and be screwed in adjusting screw(rod) top in the piston, be contained in fuel tank, the high-pressure oil pump that is contained in the base rear portion and the Low Fuel Pump at base middle part and lift head and pull that thick stick forms successively in base, the oil cylinder that is fixed on the base front portion, the oil cylinder.Portion's topic of this jack is: use inconvenient, mobile dumb.
The purpose of this utility model is: a kind of wheel shaft of aircraft flexibly jack easy to use is provided.
Technical measures of the present utility model are: based on by the telescopic oil cylinder and the piston of suit and be screwed in adjusting screw(rod) top in the piston, be contained in fuel tank, the high-pressure oil pump that is contained in the base rear portion and the Low Fuel Pump at base middle part and lift head and pull the jack that thick stick is formed successively in base, the oil cylinder that is fixed on the base front portion, the oil cylinder; On the base between oil cylinder and the fuel tank, be fixed with and carry carrying that hand forms by two upright sleeve pipes and U-shaped and carry device.
Jack of the present utility model owing to be equipped with to carry and carry device, so have easy to usely, moves good effect flexibly on base.
Fig. 1 is a structural representation of the present utility model.Fig. 2 is a birds-eye view.
Fig. 3 is the structural representation of carrying device of carrying of the present utility model.
Fig. 4 is an oil circuit scheme drawing of the present utility model.
1 is base among the figure, is fixed with oil cylinder 13 in the front portion of base 1, is set with telescopic oil cylinder 14 and piston 15 and the adjustment screw rod top 16 that is screwed in the piston 15 in oil cylinder 13 successively.At base 1 middle part fuel tank 9,10th, fuel lid, the 11st, air venting plug are housed.At base 1 rear portion high-pressure oil pump 4 and Low Fuel Pump 5 are housed, oil pump 4 and 5 piston upper end link by connecting rod and base 1 respectively.Pulling thick stick 8 for one can push two respectively and lift and pull lift in the hole of 6 and 7 rear ends oil pump is worked respectively.When just propping up the top weight, use Low Fuel Pump 5 that telescoping cylinder 14 and piston 15 are risen fast.When pull force is excessive, use high-pressure oil pump 4 instead.2 is oil return valve rods among the figure; The 3rd, upright sleeve pipe is convenient to deposit not using when pulling thick stick 8 it is inserted in the upright sleeve pipe.The utility model is on the basis of above-mentioned jack, is fixed with to carry carrying that hand 12 forms by two upright sleeve pipes 18 and U-shaped and put forward the device (see figure 3) on the base 1 between oil cylinder 13 and the oil pipe 9.17 is to be fixed on the piston that U-shaped is carried hand 12 lower ends among the figure, the 19th, be fixed on the retaining cap that stands sleeve pipe 18 upper ends, and make and carry when hand 12 is raised to deviate from.
