Abstract
The invention provides a portable hydraulic jack of an airplane. The portable hydraulic jack comprises an oil pump, a hydraulic cylinder and a tripod, wherein the oil outflow end of the oil pump is connected with the oil inflow end of the hydraulic cylinder; the tripod is composed of three raking props and a lateral pull rod; one ends of the three raking props are hinged with one end of the hydraulic cylinder; the other ends of two raking props are respectively connected with two ends of the lateral pull rod; the other ends of the oil pump and the hydraulic cylinder are fixedly connected and then hinged with the lateral pull rod; the lateral pull rod is equipped with a device capable of being rapidly dismounted; and a piston rod of the hydraulic cylinder is connected with an ejecting device. The portable hydraulic jack has the advantages that the parts can be rapidly dismounted and mounted, the tripod (raking props and pull rod) and main body parts can be folded together and then placed in a boot, thereby facilitating army transfer transportation.
Description
Technical field
The invention belongs to the hydraulic jack technical field, be specifically related to a kind of portable aircraft hydraulic jack.
Background technology
At present, the hydraulic jack that is used for aircraft has two big types, and one type is pole structure, and main support is at the wheel place; Another kind of is the tripod type structure, is supported on fuselage, wing etc. and locates, and existing tripod type aircraft hydraulic jack is because volume is big, and therefore inconvenience when army's transition training is carried is necessary to improve.
Summary of the invention
The technical matters that the present invention solves: a kind of portable aircraft hydraulic jack is provided, each parts quick release and assembling, tripod (diagonal pillar and pull bar) but, the main element folding and unfolding packs in the boot together, is convenient to army's transition transportation.
The technical scheme that the present invention adopts: portable aircraft hydraulic jack; Comprise oil pump, hydraulic actuating cylinder and tripod; Said oil pump oil outlet end is connected with the hydraulic actuating cylinder oil inlet end; Said tripod is made up of three diagonal pillars and lateral connecting rod, and said three diagonal pillar one ends are all hinged with hydraulic actuating cylinder one end, and wherein two diagonal pillar other ends are connected with the lateral connecting rod two ends respectively; The said oil pump and the hydraulic actuating cylinder other end are connected back and lateral connecting rod is hinged and lateral connecting rod is provided with the quick release device, and the piston rod of hydraulic actuating cylinder is connected with the top device.
Wherein, Said quick release device is the quick-release pin; Said lateral connecting rod is made up of pull bar I and pull bar II, and said pull bar I one end is connected with a diagonal pillar other end through the quick-release pin, and the pull bar I other end and oil pump and hydraulic actuating cylinder one end are hinged; The oil pump and the hydraulic actuating cylinder other end and pull bar II one end are hinged, and the pull bar II other end and another diagonal pillar other end are hinged.
Wherein, said top device is the concave crown head and the protruding top that is used for the top wing that is used for the top fuselage.
Further, the head side of said hydraulic actuating cylinder is provided with breather stem vent plug and lock nut.
The present invention's advantage compared with prior art:
1, each parts quick release and assembling, tripod (diagonal pillar and pull bar) but, the main element folding and unfolding boot of together packing into, be convenient to army's transition transportation;
2, overcome original high and low pressure oil circuit separately, seal structure complex, the problem of poor reliability;
3, oil pump is a double pump, and jack jacking has fast improved work efficiency, has alleviated working strength.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a protruding top structure scheme drawing of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing 1,2 a kind of embodiment of the present invention is described.
Portable aircraft hydraulic jack; Comprise oil pump 5, hydraulic actuating cylinder 4 and tripod 7; Said oil pump 5 oil outlet ends are connected with hydraulic actuating cylinder 4 oil inlet ends; Said tripod 7 is made up of three diagonal pillars 10 and lateral connecting rod 9, and said three diagonal pillar 10 1 ends are all hinged with hydraulic actuating cylinder 4 one ends, and wherein two diagonal pillar 10 other ends are connected with lateral connecting rod 9 two ends respectively; Said oil pump 5 and hydraulic actuating cylinder 4 the other ends hinged and lateral connecting rod 9 of back and lateral connecting rod 9 that is connected is provided with the quick release device, the piston rod of hydraulic actuating cylinder 4 with come directly towards device and be connected.
Said quick release device is a quick-release pin 6; Said lateral connecting rod 9 is made up of pull bar I 11 and pull bar II12; Said pull bar I11 one end is connected with diagonal pillar 10 other ends through quick-release pin 6; Pull bar I 11 other ends and oil pump 5 are hinged with hydraulic actuating cylinder 4 one ends, and oil pump 5 is hinged with hydraulic actuating cylinder 4 other ends and pull bar II 12 1 ends, and pull bar II 12 other ends and another diagonal pillar 10 other ends are hinged.Said top device is the concave crown head 2 and the protruding top 14 that is used for the top wing that is used for the top fuselage.The head side of said hydraulic actuating cylinder 4 is provided with breather stem vent plug 8 and lock nut 3.
Principle of work: after jack is finished using; Quick-release pin 6 is pulled down, and pull bar I11 and pull bar II12 pack up to hydraulic actuating cylinder 4 directions, and three diagonal ligaments 10 also can be packed up with the main part body boot of packing into and get final product; When needs used jack, order was just opposite.
The above only is a preferred embodiments of the present invention, so all equivalences of doing according to the described structure of patent application right claimed range of the present invention, characteristic and principle change or modify, includes in patent application right claimed range of the present invention.
