The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
With reference to Fig. 1, a kind of inversion type hydraulic oil circuit balance lifting machine comprises the chassis; Two ends vertically are provided with the head tree 1 and the secondary column 2 of band U type groove on the described chassis; Be respectively equipped with on described head tree 1 and the secondary column 2 one can longitudinal sliding motion in U type groove slide unit 3, slide unit 3 outsides are equipped with hold-down arm 4; The top of described head tree 1 and secondary column 2 is equipped with sinciput end casing 5 and top, back cover plate 6; Described head tree is provided with power unit 7, is respectively equipped with inverted master cylinder 8 and inverted auxiliary oil cylinder 9 on the slide unit 3 in described head tree 1 and the secondary column 2; Be respectively equipped with check valve 10 on the piston of described master cylinder 8 and auxiliary oil cylinder 9; Be connected by oil pipe 11 between described master cylinder 8 epicoeles and auxiliary oil cylinder 9 cavity of resorptions; Master cylinder 8 cavity of resorptions are connected with power unit 7 by oil pipe 11; Described auxiliary oil cylinder 9 epicoeles are connected with power unit 7 by oil return pipe 12; Described power unit 7 connects motor 12.Be provided with the holder palm 13 between described head tree 1 and secondary column 2 bottoms; Pass through bolted connection between the described holder palm 13 and head tree 1 and the secondary column 2.Described power unit 7 is provided with direction switch button 14 and descends unloading handle 15.Described power unit 7 is provided with protective cover 15 and flow valve 16.Be provided with release steel rope 17 between described head tree 1 and the secondary column 2.
Hydraulic efficiency pressure system of the present utility model adopts master cylinder and auxiliary oil cylinder control balance, one-way relief valves is equipped with in master cylinder and auxiliary oil cylinder inside, this check valve is installed on the piston, compares with the hydraulic efficiency pressure system of in the past dependence noticeable degree feed circuit, and structure is more simple and convenient with operation.Its principle is: power unit is to master cylinder cavity of resorption fuel feeding, piston can move to the master cylinder top thereupon, when piston touched the master cylinder top cover, the check valve on the piston can be opened, at this moment, hydraulic oil can flow into the auxiliary oil cylinder cavity of resorption through oil pipe by the master cylinder top, the auxiliary oil cylinder piston can be thereupon to the motion of auxiliary oil cylinder top, and when piston touched the auxiliary oil cylinder top cover, the check valve on the piston can be opened, at this moment, hydraulic oil can flow back in the power unit through oil return pipe.Because common lifting machine is when normal fortune, when piston runs to the oil cylinder top, system pressure increases suddenly.If continue to pin the rising button this moment, power unit probably is damaged.This kind of lifting machine is owing to install check valve in oil cylinder piston, therefore can avoid system pressure to increase suddenly, and cause the damage of power unit, so, venting problem when the design of this check valve not only can solve commissioning device simultaneously can also be as the inhibiting device of hydraulic pressure.The design plan of inverted master cylinder and auxiliary oil cylinder has not only been saved the space, and has strengthened the load-carrying capacity of oil cylinder.Tradition two post lifting machines adopt takes blame for others, and promptly oil cylinder one end is fixed on the base plate, be connected with slide unit by the oil cylinder urceolus, and the realization up-and-down movement, but this scheme and needs column and slide unit to reserve enough space mounting oil cylinders to the having relatively high expectations of oil cylinder piston bar.Want the power that reaches same, the diameter minimum of the piston rod of master cylinder should be Φ 34mm, oil cylinder urceolus diameter is Φ 66mm, and the utility model adopts the design plan of being inverted oil cylinder, reach same power, the diameter of the piston rod of master cylinder only is Φ 22mm, and oil cylinder urceolus diameter only is Φ 58mm; Calculate from economical with materials, greatly reduce cost.This inversion type hydraulic oil circuit balance two post lifting machines improve the mechanical part design at the merits and faults of fully analyzing original structure in addition, and structure is more become rationally, have strengthened the non-deformability of parts.The equipment gross weight is 350KG, and the use of having saved steel has greatly reduced unnecessary waste, has saved manufacturing cost.
Exhaust of the present utility model, debugging step is:
1. when lifting machine height in minimum altitude the time, pin the direction switch button, this moment, head tree end slide unit can rise.When head tree end slide unit rises to top, continue to pin the direction switch button.At this moment secondary stud end slide unit can rise, and rises to the about five seconds of top until secondary stud end slide unit, and gas will be discharged in the oil cylinder.
2. pinning descends lets out a year arm cook, reduces to minimum until slide unit.At this moment fuel tank should be charged into the oil (unsuitable overfill) of capacity, pin the direction switch button, this moment, column two ends slide unit can rise synchronously.Rise to the about five seconds of top until the two ends slide unit, gas will all be discharged in the oil cylinder.
3. pinning once more descends lets out and carries an arm cook, if when phenomenon such as " creeping ", " beating " is arranged when descending, repetitive operation is guaranteed can get on the bus after the balance several times.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
