Description

The simple type hydraulic vehicle lift

Affiliated technical field

The utility model relates to a kind of automobile hydraulic lifting device, belongs to mechanical field.

Background technology

At present, auto jack commonly used mostly adopts high column structure, and two column auto jacks are generally lifted auto body, and four column auto jacks are generally lifted automotive wheel, also has such as minimum facilities such as trenches in addition.These equipment cost height, mechanism size and weight are generally all bigger, are difficult for after the installation moving, and use when being not suitable for miniature car maintenance factory or maintenance department to maintenances such as automotive engine, chassis.

Summary of the invention

In order to overcome existing auto jack scantling of structure and the big deficiency of weight, the purpose of this utility model provides a kind of simple type hydraulic vehicle lift, it is simple in structure, in light weight, and is easy to use, is particularly suitable for miniature car maintenance factory, maintenance department to miniature car maintenance use.

The technical scheme in the invention for solving the technical problem: the version that adopts vertical lift, provide power by hydraulic efficiency pressure system, the oil cylinder piston bar promotes connecting rod mechanism, drive inside and outside hold-down arm pallet is lifted, thereby the automobile that will be placed on the swing arm supporting base rises.Adopt the connecting rod of belt length cylindrical void, oil cylinder and inside and outside hold-down arm can be lain on the base when retracted state fully, thereby reduced the height when retracted state (not working).Four removable and rotating swing arms are set, by regulating the position of swing arm, can support the automobile of disalignment distance on the one hand, reduce weight; When retracted state, the swing arm rotation vertically can be placed, on the other hand to reduce the width when not working.

The beneficial effects of the utility model are, move conveniently, be fit to very much miniature car maintenance factory, maintenance department to miniature car maintenance use, and it is little to take up room when not working.

The specific embodiment

A kind of simple type hydraulic vehicle lift mainly is made up of base 1, oil cylinder 2, outer hold-down arm 3, interior hold-down arm 4, pallet 14, swing arm 17 etc.Be welded with non-friction guide 6, locking plate and cylinder support etc. on the base 1.One end of outer hold-down arm 3 is hinged by bearing pin and base 1, and the other end is installed roller 24, can roll in the track base 16 of pallet 14; One end of interior hold-down arm 4 is hinged by bearing pin and pallet 14, and the other end is installed roller 24, can roll in the non-friction guide 6 of base 1; Inside and outside hold-down arm is equipped with an end of roller respectively by the pipe link solder together, near on the pipe link of interior hold-down arm inboard two locking bars 5 are being set respectively, locking bar 5 can rotate on pipe link, the support end of locking bar 5 withstands on the locking plate of base 1 when work, to pin roller reliably, prevent that automobile from plunking down; The center of inside and outside hold-down arm connects with rotating shaft 8, can 8 rotate around the shaft.Interior hold-down arm inboard is welded with bearing pin 9, bearing pin 9 connects with the rectangular nose end of connecting

rod

10,11, bearing pin 9 can slide in the strip hole of connecting

rod

10,11, the other end of connecting

rod

10,11 connects with hinge 23, hinge 23 also connects with the piston rod earrings of oil cylinder 2, and the other end of oil cylinder 2 connects with hinge 7 by earrings.Pallet 14 is a weld assembly, is made of slide rail 12, cover plate 13, crossbeam 15, track base 16 etc.Four swing arms 17 are arranged on the slide rail 12 of pallet 14, and swing arm 17 can be slided on slide rail 12, supports the needs of disalignment apart from vehicle to adapt to.Swing arm 17 mainly is made up of bearing 18, nut seat 19, support arm 20, rotating shaft 21 and slide rail seat 22 etc., and support arm 20 connects with rotating shaft 21 on being installed in slide rail seat 22, and can 21 rotate around the shaft; Support arm 20 is provided with elongated slot, and nut seat 19 can move in elongated slot, to adapt to the needs that support different chassis width vehicles; The height of bearing 18 can be regulated by screw rod on it and nut seat 19.

When not working, be in and keep flat retracted state, the oil cylinder piston bar is regained, and lies on the base together with inside and outside hold-down arm, and pallet falls fully, and bottom-to-top-height is no more than 110mm, and total weight is no more than 200kg, regains swing arm simultaneously, the parallel side that leans against slide rail 12.

During work, running car to be keeped in repair to the utility model, is rotated four swing arms 17 perpendicular to slide rail 12, and move on the suitable position, follow the position of adjustment nut seat 19, the bearing 18 on the rotating nut seat 19 withstands on the car chassis bearing then.Handle change-over valve, the oil cylinder piston bar is stretched out, boost hinge 23, driving interior hold-down arm by connecting

rod

10,11 moves, driving outer hold-down arm by rotating shaft 8 simultaneously moves, at this moment, interior hold-down arm pin jointed end maintains static, and movable end is rolled outer hold-down arm pin jointed end vertical uplift by roller 24 in non-friction guide 6, movable end is rolled in track base 16 by roller 24, the pallet 14 and vertical rise of getting on the car thereof when arriving predetermined altitude, are handled change-over valve and are made oil cylinder stop to stretch out, and locking bar 5 withstood on the locking plate, just can carry out maintenance activity then.

After maintenance activity finishes, at first locking bar 5 is lifted from locking plate, change 180 ° around pipe link, the support end that makes locking bar 5 up, handle change-over valve then, make the withdrawal of oil cylinder piston bar, fall pallet 14 and automobile, after pallet 14 falls fully, regain swing arm, automobile is just driven away end-of-job in the parallel side that leans against slide rail 12.
