Technical field
The utility model relates to the oil cylinder technical field of synchronization motion, relates in particular to the device of the large load operation platform of the concentric piston rod oil cylinder movement of a kind of relative type motor.
Background technique
At present, in engineering, when using the large load weight of oil cylinder movement, the general easy piston rod that oil cylinder is stretched out, the distortion that is squeezed, causes the leakage of oil of oil cylinder in mobile large load weight, causes oil cylinder to damage when serious, the oil cylinder that needs repairing, or change oil cylinder, affect project progress.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides the concentric double rod cylinder of a kind of relative type motor to move the device of large load operation platform.
For achieving the above object, the technical solution of the utility model is:
The device of the large load operation platform of the concentric piston rod oil cylinder movement of a kind of relative type motor, have two relative concentric double rod cylinders, two relative one end piston rods of concentric double rod cylinder are fixedly connected with the large load operation platform 5 on the interior guide rail of long pipeline 6 by connecting rod 4 respectively; Each concentric double rod cylinder is made up of the double piston-rod 3 that is positioned at the concentric connection piston 2 of integral type concentric cylinder 1.
A device for the large load operation platform of the concentric piston rod oil cylinder movement of relative type motor, described integral type concentric cylinder 1 is the elongated oil cylinder of the external ouput force of tension state.
A device for the large load operation platform of the concentric piston rod oil cylinder movement of relative type motor, the slenderness ratio of double piston-rod 3 diameters of straight 2 footpaths of described piston and every end is more than or equal to 5.
A device for the large load operation platform of the concentric piston rod oil cylinder movement of relative type motor, described double piston-rod 3 is greater than the High Yield Stress Steel of 1000MPa for yield strength.
Owing to adopting technological scheme as above, the utlity model has following beneficial effect:
The utility model is the device of the large load operation platform of the concentric piston rod oil cylinder movement of relative type motor, can use worktable and the weight of the large load of the thin oil cylinder movement of length of two concentric piston rods of relative type motor, by long thin oil cylinder pulling force back and forth, pull worktable and the weight of large load, avoid stretching out the piston rod of oil cylinder, the distortion that is squeezed, and cause leakage of oil, the damage of oil cylinder, reduce the maintenance of oil cylinder, improved project progress.It is simple in structure, and reliability is high, low cost of manufacture.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Accompanying drawing l is the structural representation of the device of the large load operation platform of the concentric piston rod oil cylinder movement of relative type motor.
In figure: 1, integral type concentric cylinder, 2, piston, 3, double piston-rod, 4, connecting rod, 5, large load operation platform, 6, long pipeline.
Embodiment
As shown in Figure 1, the device of the large load operation platform of the concentric piston rod oil cylinder movement of a kind of relative type motor, have two relative concentric double rod cylinders, two relative one end piston rods of concentric double rod cylinder are fixedly connected with the large load operation platform 5 on the interior guide rail of long pipeline 6 by connecting rod 4 respectively; Each concentric double rod cylinder is made up of the double piston-rod 3 that is positioned at the concentric connection piston 2 of integral type concentric cylinder 1.
Integral type concentric cylinder 1 is wherein the elongated oil cylinder of the external ouput force of tension state, and the slenderness ratio of double piston-rod 3 diameters of straight 2 footpaths of described piston and every end is more than or equal to 5.Described double piston-rod 3 is greater than the High Yield Stress Steel of 1000MPa for yield strength.
When use, two relative concentric double rod cylinders are installed respectively at the two ends of long pipeline 6, when large load operation platform 5 moves to a direction, oil inlet hole oil-feed in the rod end chamber that concentric double rod cylinder one end of long pipeline 6 one end is connected with connecting rod 4, the piston rod return of this end, moves to this direction by the large load operation platform 5 on connecting rod 4 sliding guides; When large load operation platform 5 moves to contrary another direction, oil inlet hole oil-feed in the rod end chamber that in the concentric double rod cylinder of long pipeline 6 the other ends, one end is connected with connecting rod 4, the piston rod return of this end, moves to this direction by the large load operation platform 5 on connecting rod 4 sliding guides;
In the concentric double rod cylinder at above-mentioned long pipeline 6 two ends, be connected with connecting rod 4 the piston rod large load operation platform 5 of alternately pulling back, reach large load operation platform 5 and move back and forth, avoided piston rod to stretch out being squeezed the stress that is out of shape and the damage of oil cylinder.
