Description
Technical field
The present invention relates to the oil cylinder technical field of synchronization action, particularly relate to a kind of integral type non-concentric piston rod oil cylinder and move
The device of dynamic 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 integral type non-concentric piston rod oil cylinder movement big load work
The device of station.
For achieving the above object, the technical scheme is that
The device of a kind of integral type non-concentric piston rod oil cylinder movement big load operation platform, has two identical first oil
Cylinder connects and composes by housing and the second oil cylinder reverse parallel connection are fixing, and described first oil cylinder inner piston rod passes through connecting rod and is positioned at
Big load operation platform one end on guide rail is fixing to be connected；The second reverse oil cylinder inner piston rod passes through connecting rod and is positioned on guide rail
The big load operation platform other end fixing connect.
A kind of device of integral type non-concentric piston rod oil cylinder movement big load operation platform, described the first oil cylinder, second
Oil cylinder is the elongated oil cylinder of the external power output of tension state, and its piston diameter is more than or equal to 5 with the draw ratio of diameter of piston rod；Piston
Bar is the high yield stress steel that yield strength is more than 1000MPa.
Owing to using technical scheme as above, the present invention has a following beneficial effect:
The present invention can use workbench and the weight of the long big load of thin oil cylinder movement, by long thin oil cylinder drawing back and forth
Power, 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 oil cylinder
Leakage of oil, damage, decrease the maintenance of oil cylinder, improve project progress.Its simple in construction, reliability is high, low cost of manufacture.
First oil cylinder of the dual action cylinder of the present invention, the second oil cylinder more adapt to the occasion that elongated oil cylinder uses, and emphasize
The external power output of tension state, other end stress is the least, it is ensured that do not have a depression bar deformation, the first oil cylinder of dual action cylinder, the
The piston diameter of two oil cylinders and the draw ratio of diameter of piston rod are more than or equal to 5；Piston rod material is higher yield strength, as
30CrMnSi, 40CrMoV, 60Si2MnA, 40CrNiMo, 55CrSi, 18Ni300 etc., yield strength is more than 1000MPa, so
Under oil pressure higher state, it 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.
Accompanying drawing 1 is the structural representation that non-concentric double-rod oil cylinder connects mobile working platform.
In figure: 1, the first oil cylinder, the 2, second oil cylinder, 3, big load operation platform, 4, connecting rod.
Detailed description of the invention
As it is shown in figure 1, the device of a kind of integral type non-concentric piston rod oil cylinder movement big load operation platform, there are two phases
The first same oil cylinder 1 connects and composes by housing and the second oil cylinder 2 reverse parallel connection are fixing, and described first oil cylinder 1 inner piston rod leads to
Big load operation platform 3 one end crossing connecting rod 4 and be positioned on guide rail is fixing to be connected；The second reverse oil cylinder 2 inner piston rod passes through
Connecting rod 4 is fixing with big load operation platform 3 other end being positioned on guide rail to be connected.
During use, use the pulling force of the first oil cylinder 1 inner piston rod return of integral type non-concentric piston rod oil cylinder, by even
Big load operation platform 3 on extension bar 4 sliding guides moves to A direction, when big load operation platform 3 moves in B direction round about,
Use the pulling force of the second oil cylinder 2 inner piston rod return, by the big load operation platform 3 on connecting rod 4 sliding guides to phase negative side
Move to B direction；It is embodied as follows:
1 moves to A direction when big load operation platform 3, and fuel feed hole oil-feed in the first oil cylinder 1 rod chamber is lived in the first oil cylinder 1
Stopper rod return, is moved to A direction by the big load operation platform 3 on connecting rod 4 sliding guides, enters in the second oil cylinder 2 rodless cavity
Oilhole oil-feed, assists the second oil cylinder 2 inner piston rod to stretch out；
2 move to B direction when big load operation platform 3, and fuel feed hole oil-feed in the second oil cylinder 2 rod chamber is lived in the second oil cylinder 2
Stopper rod return, is moved to B direction by the big load operation platform 3 on connecting rod 4 sliding guides, enters in the first oil cylinder 1 rodless cavity
Oilhole oil-feed, assists the first oil cylinder 1 inner piston rod to stretch out；
Alternately pulling back of 3 above-mentioned first oil cylinder 1 inner piston rods and the second oil cylinder 2 inner piston rod, reaches big load operation platform 3
Move back and forth, it is to avoid piston rod is squeezed the stress of deformation and the damage of oil cylinder.
First oil of the dual action cylinder of the device of above-mentioned integral type non-concentric piston rod oil cylinder movement big load operation platform
Cylinder, the second oil cylinder more adapt to the occasion that elongated oil cylinder uses, and emphasize that other end stress is the least in tension state external power output, protect
Card does not haves depression bar deformation, the first oil cylinder of dual action cylinder, the piston diameter of the second oil cylinder and the major diameter of diameter of piston rod
Ratio is more than or equal to 5；Piston rod material is higher yield strength, 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.
