Abstract

The invention relates to the technical field of oil cylinders with synchronization action, and discloses a device of an integrated concentric piston rod oil cylinder for moving a heavy-load working table. The device comprises an integrated concentric cylinder body 1, a piston 2, a double piston rod 3, wherein the double piston rod 3 of the piston 2 which is concentrically connected and located in the integrated concentric cylinder body respectively penetrates through two ends of the integrated concentric cylinder body so as to be connected with a connecting rod 4 connected with the heavy-load working table 5. According to the device, the heavy-load working table and weights are pulled through back-and-forth pulling force of a long and thin oil cylinder, so that the phenomena of oil leakage and damage of the oil cylinder caused by the reason that the piston rod stretched out of the oil cylinder is extruded and deformed are avoided, the maintenance of the oil cylinder is reduced, the yield strength characteristic of materials of the piston rod under the state of higher oil pressure is realized, and the works programme is improved. The device is simple in structure, high in reliability and low in manufacturing cost.

Description

The device of the large load operation platform of the concentric piston rod oil cylinder movement of integral type
Technical field
The present invention relates to the oil cylinder technical field of synchronization motion, relate in particular to the device of the large load operation platform of the concentric piston rod oil cylinder movement of a kind of integral type.
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 invention provides the device of the large load operation platform of the concentric piston rod oil cylinder movement of a kind of integral type.
For achieving the above object, technological scheme of the present invention is:
The device of the large load operation platform of the concentric piston rod oil cylinder movement of a kind of integral type, comprise: integral type concentric cylinder 1, piston 2, double piston-rod 3, the double piston-rod 3 that is positioned at the concentric piston 2 connecting of integral type concentric cylinder is connected with the connecting rod 4 that is connected large load operation platform 5 through the two ends of integral type concentric cylinder 1 respectively.
A device for the large load operation platform of the concentric piston rod oil cylinder movement of integral type, 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 integral type, 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 integral type, 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 present invention has following beneficial effect:
The present invention is the device of the large load operation platform of the concentric piston rod oil cylinder movement of a kind of integral type, can use worktable and the weight of the large load of the long thin oil cylinder movement of the concentric piston rod of integral type, by long thin oil cylinder pulling force back and forth, pull worktable and the weight of large load, avoided 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.
The present invention more adapts to the occasion that elongated oil cylinder is used, and emphasizes that the other end is stressed very little in the external ouput force of tension state, guarantees there will not be depression bar distortion, and the slenderness ratio of the diameter of piston rod of its piston diameter and every end is more than or equal to 5; Piston rod material is higher yield strength, and as 30CrMnSi, 40CrMoV, 60Si2MnA, 40CrNiMo, 55CrSi, 18Ni300 etc., yield strength surpasses 1000MPa, under oil pressure higher state, more easily brings into play piston rod material yield strength characteristics like this.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Accompanying drawing l is the structural representation that the concentric double rod cylinder of integral type connects shuttle table.
In figure: 1, integral type concentric cylinder, 2, piston, 3, double piston-rod, 4, connecting rod, 5, large load operation platform.
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 integral type, comprise: integral type concentric cylinder 1, piston 2, double piston-rod 3, be positioned at the concentric double piston-rod 3 that connects piston 2 of integral type concentric cylinder and through the two ends of integral type concentric cylinder 1, be connected with the connecting rod 4 that is connected large load operation platform 5 respectively.
The device of the large load operation platform of the concentric piston rod oil cylinder movement of this integral type, described oil cylinder is the elongated oil cylinder of the external ouput force of tension state, the slenderness ratio of the diameter of piston rod of its piston diameter and every end is more than or equal to 5; Piston rod is the High Yield Stress Steel that yield strength is greater than 1000MPa.As 30CrMnSi, 40CrMoV, 60Si2MnA, 40CrNiMo, 55CrSi, 18Ni300 etc.
During use, adopt the pulling force of the piston rod return of one end in concentric double piston-rod 3 oil cylinders of integral type, large load operation platform 5 on connecting rod 4 sliding guides is moved to A direction, when large load operation platform 5 round about B direction move, adopt the pulling force of the piston rod return of the other end in concentric double piston-rod 3 oil cylinders of integral type, by the large load operation platform 5 on connecting rod 4 sliding guides round about B direction move; Specifically be implemented as follows:
When large load operation platform 5 moves to A direction, oil inlet hole oil-feed in the rod end chamber of one end in concentric double piston-rod 3 oil cylinders of integral type, the piston rod return of this end, moves to A direction by the large load operation platform 5 on connecting rod 4 sliding guides;
When large load operation platform 5 moves to B direction, oil inlet hole oil-feed in the rod end chamber of the concentric double rod cylinder 3 interior the other ends of integral type, the piston rod return of this end, moves to B direction by the large load operation platform 5 on connecting rod 4 sliding guides;
The piston rod at the concentric double rod cylinder of the above-mentioned integral type 3 interior two ends large load operation platform 5 of alternately pulling back, reaches large load operation platform 5 and moves back and forth, and has avoided piston rod to stretch out being squeezed the stress of distortion and the damage of oil cylinder.
