Description

A kind of force-doubling type concentric piston rod oil cylinder moves the device of big load operation platform
Technical field
The present invention relates to the oil cylinder technical field of synchronization action, particularly relate to a kind of force-doubling type concentric piston rod oil cylinder and move The device of big load operation platform.
Background technology
At present, in engineering, the when of using oil cylinder movement big load weight, the general piston easily oil cylinder stretched out Bar, be squeezed deformation, causes oil cylinder leakage of oil mobile big load weight when, causes oil cylinder to damage, need time serious Maintenance oil cylinder, or change oil cylinder, affect project progress.
Summary of the invention
For overcoming the deficiencies in the prior art, the present invention provides a kind of force-doubling type concentric piston rod oil cylinder to move big load operation The device of platform.
For achieving the above object, the technical scheme is that
A kind of force-doubling type concentric piston rod oil cylinder moves the device of big load operation platform, including: concentric double rod cylinder, Selector bar 6, described concentric double rod cylinder is connected double piston-rod 3 structure of piston 2 with one heart by being positioned at integral type concentric cylinder 1 Become, stretch out that double piston-rod 3 two ends of integral type concentric cylinder 1 are fixing with selector bar 6 two ends respectively to be connected, be connected with selector bar 6 Piston rod top be connected by connecting rod 4 and the big load operation platform 5 being positioned on long pipeline 7 guide rail are fixing.
A kind of force-doubling type concentric piston rod oil cylinder moves the device of big load operation platform, described integral type concentric cylinder 1 Elongated oil cylinder for the external power output of tension state.
A kind of force-doubling type concentric piston rod oil cylinder moves the device of big load operation platform, described piston 2 diameter with often hold The draw ratio of double piston-rod 3 length more than or equal to 5.
A kind of force-doubling type concentric piston rod oil cylinder moves the device of big load operation platform, and described double piston-rod 3 is surrender The intensity high yield stress steel more than 1000MPa.
Owing to using technical scheme as above, the present invention has a following beneficial effect:
The present invention is the device that force-doubling type concentric piston rod oil cylinder moves big load operation platform, it is possible to use long thin oil cylinder to move The workbench of dynamic big load and weight, by long thin oil cylinder pulling force back and forth, pull workbench and the weight of big load, it is to avoid Stretching out the piston rod of oil cylinder, be squeezed deformation, and causes the leakage of oil of oil cylinder, damage, decreases the maintenance of oil cylinder, improves work Cheng Jindu.Its simple in construction, reliability is high, low cost of manufacture.
The present invention more adapts to the occasion that elongated oil cylinder uses, and emphasizes that other end stress is the least in tension state external power output, Ensureing not have depression bar deformation, its piston diameter is more than or equal to 5 with the draw ratio of diameter of piston rod;Piston rod material is higher Yield strength, such as 30CrMnSi, 40CrMoV, 60Si2MnA, 40CrNiMo, 55CrSi, 18Ni300 etc., yield strength exceedes 1000MPa, so under oil pressure higher state, is more easy to play piston rod material yield strength characteristic.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.

Detailed description of the invention
As it is shown in figure 1, a kind of force-doubling type concentric piston rod oil cylinder moves the device of big load operation platform, including: the most double Piston rod oil cylinder, selector bar 6, described concentric double rod cylinder is connected piston 2 with one heart by being positioned at integral type concentric cylinder 1 Double piston-rod 3 is constituted, described in stretch out double piston-rod 3 two ends of integral type concentric cylinder 1 respectively fixing with selector bar 6 two ends even Connecing, the piston rod of described integral type concentric cylinder 1 one end is connected end and the big load work on guide rail in long pipeline 7 with selector bar 6 Station 5 is fixing to be connected.
Wherein integral type concentric cylinder 1 is the elongated oil cylinder of the external power output of tension state.Piston 2 diameter and the dual-active often held The draw ratio of stopper rod 3 diameter is more than or equal to 5.Double piston-rod 3 is more than the high yield stress steel of 1000MPa for yield strength.Live Stopper rod material is higher yield strength, such as 30CrMnSi, 40CrMoV, 60Si2MnA, 40CrNiMo, 55CrSi, 18Ni300 etc., Yield strength is more than 1000MPa, so under oil pressure higher state, is more easy to play piston rod material yield strength characteristic.
During use, the concentric double rod cylinder of integral type is installed in one end of long pipeline 7, and at the concentric dual-active of integral type Installing selector bar 6 between the two ends concentric piston masthead end of rod cylinder, connecting rod is passed through on the piston rod top being connected with selector bar 6 4 fixing with the big load operation platform 5 being positioned on guide rail are connected.It is embodied as follows:
When big load operation platform 5 moves to a direction, one end in the concentric double rod cylinder of integral type of long pipeline 7 one end Fuel feed hole oil-feed in the rod end chamber being connected with connecting rod 4, the piston rod return of this end, by connecting rod 4 sliding guides Big load operation platform 5 moves to the direction;
When big load operation platform 5 moves in the opposite direction, in the concentric double rod cylinder of integral type one end not be connected Fuel feed hole oil-feed in what bar 4 connected rod end chamber, this piston rod return, pull the conversion installed between two concentric piston masthead ends Bar 6, makes selector bar 6 promote connecting rod 4, big load operation platform 5 to move to the direction, and selector bar 6 has the power doubled;
Be connected with connecting rod 4 in the concentric double rod cylinder of integral type of above-mentioned long pipeline 7 one end piston rod and two The selector bar 6 installed between concentric piston masthead end is alternately pulled back big load operation platform 5, reaches big load operation platform 5 and carries out back and forth Mobile, it is to avoid piston rod stretches out stress and the damage of oil cylinder of the deformation that is squeezed.The movement big load weight of this synchronization action The device of thing, more adapts to the occasion that elongated oil cylinder uses, emphasizes that other end stress is the least in tension state external power output, it is ensured that Do not have depression bar deformation.
