Above-mentioned Integral hydraulic draws top multiple purpose aeroplane, and wherein, described claw hook is arc knee claw hook, and one end of described arc knee claw hook is hook solid, and the other end is provided with adjustment hole and is connected with lever arm.
Above-mentioned Integral hydraulic draws top multiple purpose aeroplane, and wherein, described hook seat is the sleeve of hollow, is provided with the internal thread matched with external screw thread on threaded rod, is provided with support bar and is connected with lever arm outside described sleeve inside described sleeve.
Above-mentioned Integral hydraulic draws top multiple purpose aeroplane, and wherein, the number of described claw hook is 2 ~ 4, and described multiple claw hook is spacedly distributed along the excircle of hook seat.
The utility model contrast prior art has following beneficial effect: the Integral hydraulic that the utility model provides draws top multiple purpose aeroplane, pressurized handgrip need only be swung by a small margin with hand and make the quiet pulling force of straight line and detachable part, not by place, position limitation, convenient and labor-saving, compact conformation, stable performance, also can carry out the work such as lifting, top act, straightening, pressure test in addition.
Accompanying drawing explanation
Fig. 1 is that the utility model Integral hydraulic draws top multiple purpose aeroplane structural representation.
In figure:
1 claw hook 2 is bored pinnacle and to be cut somebody's hair 3 threaded rods
4 hook seat 5 axial compression starting handle 6 actuating rod connectors
7 hydraulic cylinder 8 adjustment hole 9 lever arms
10 handle 11 support bars
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model will be further described.
Fig. 1 is that the utility model Integral hydraulic draws top multiple purpose aeroplane structural representation.
Refer to Fig. 1, the Integral hydraulic that the utility model provides draws top multiple purpose aeroplane to comprise claw hook 1, hydraulic cylinder 7 and handle 10, wherein, one end of the piston rod of described hydraulic cylinder 7 is connected with threaded rod 3, the other end is connected with handle 10 by axial compression starting handle 5, actuating rod connector 6, be arranged with hook seat 4 outside described threaded rod 3, described claw hook 1 is fixed on hook seat 4 by lever arm 9, and the end of described threaded rod 3 is provided with cone pinnacle and cuts somebody's hair 2.
The Integral hydraulic that the utility model provides draws top multiple purpose aeroplane, and described claw hook 1 is arc knee claw hook, and one end of described arc knee claw hook is hook solid, and the other end is provided with adjustment hole 8 and is connected with lever arm 9.Described hook seat 4 is the sleeve of hollow, is provided with the internal thread matched with external screw thread on threaded rod 3, is provided with support bar 11 and is connected with lever arm 9 outside described sleeve inside described sleeve.The number of described claw hook 1 is 2 ~ 4, and described multiple claw hook 1 is spacedly distributed along the excircle of hook seat 4.
The Integral hydraulic that the utility model provides draws top multiple purpose aeroplane, directly to advance movement, therefore push rod itself does not rotate with axial compression starting handle 5.Hook seat 4 directly can make again the roll adjustment of forward-reverse with screw thread, as long as swing by a small margin before and after handle during operation, piston rod moves forward, and the corresponding retrogressing of hook 1, pulls out pulled object.Not only easy to operate, use laborsaving, not with place restriction, and compact conformation, use flexibly, lightweight, volume is little, easy to carry, is applicable to factory, repairs place.Safety is born a heavy burden 5 ~ 50 tons, and axle center is effectively stretched apart from 50 ~ 70mm, longitudinally the longlyest draws apart from 150 ~ 400mm, horizontal maximum outside diameter 200 ~ 600mm.Concrete use procedure is as follows:
1, according to the external diameter of pulled object, distance and load force should be drawn, select the hydraulic pulling top multiple purpose aeroplane of corresponding tonnage before using, must guard against overload and using, avoid damaging; During use, oil return valve rod screws by first handle in the direction of the clock.
2, hook seat 4 is adjusted to claw hook 1 and catch drawn object.
3, inserted by handle and to press in hand hole pressing back and forth, piston rod steadily advances, and the corresponding retrogressing of claw hook 1, pulls out pulled object.
4, should quit work when hydraulic screw extractor piston rod does not pull out object in impulse stroke, unclamp oil return valve rod, allow piston rod shrink back, mix up rear second time and repeat 1,2,3 steps again to only pulling out object.
5, piston rod is shunk back, slightly need only be loosened by counter clockwise direction by oil return valve rod with hand, piston starting handle bounces back under the action of the spring gradually.
In addition, for preventing overload from causing facility to damage, be provided with overload automatic relieving valve in hydraulic means, when pulled object exceedes nominal load, overloading valve can automatic deloading, and change (answering) and select more large-tonnage hydraulic pulling top multiple purpose aeroplane.Use in this hydraulic pulling top multiple purpose aeroplane-5 DEG C ~ 45 DEG C, adopt (GB443-84) N15 machinery oil; Use in-20 DEG C ~-5 DEG C, adopt (GB442-64) synthetic spindle oil.The piston rod outreach of hydraulic cylinder must not exceed performance parameter table setting, please notes that on piston rod, red marking line is extreme position after exposing, and should quit work during use.Hook seat 4 had better not use at thread head 15mm place, in order to avoid cause damage.
Although the utility model discloses as above with preferred embodiment; so itself and be not used to limit the utility model; any those skilled in the art; not departing from spirit and scope of the present utility model; when doing a little amendment and perfect, therefore protection domain of the present utility model is when being as the criterion of defining with claims.
