Description
Technical field
This utility model relates to hydraulic drive field, specifically a kind of hydraulic cylinder self locking apparatus.
Background technology
Hydraulic energy is changed into mechanical energy, does the hydraulic actuator of straight reciprocating motion (or oscillating motion) by cylinder pressure.
Its simple in construction, reliable operation.When realizing moving back and forth with it, deceleration device can be removed from, and there is no drive gap,
Stable movement, is therefore used widely in the hydraulic system of various machineries.Hydraulic cylinder is carried out actually used often needs
The hydraulic jack that self-locking, such as Auto repair shop use, needs to make automobile to be maintained at certain height and position to facilitate repairing,
When hydraulic jack rises to certain altitude, carry out self-locking, and must assure that self-locking high efficient and reliable, in case safe thing occurs
Therefore.But existing hydraulic cylinder self locking mode uses hydraulic control one-way valve machine loop mostly, makes hydraulic cylinder be maintained at certain position.By
In hydraulic valve technical merit and the restriction of hydraulic circuit installation quality, during hydraulic locking cylinder, at hydraulic valve core or
Often there is the situation of leakage in line connection, causes hydraulic locking cylinder not thorough, and locking effect is poor.
Utility model content
The purpose of this utility model is to provide a kind of hydraulic cylinder self locking apparatus, with asking of solving to propose in above-mentioned background technology
Topic.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of hydraulic cylinder self locking apparatus, including: hydraulic cylinder, piston, piston rod, tooth bar, gear, ratchet, small-sized hydraulic
Cylinder, bearing, bar and ratchet, described piston rod is arranged on piston rodless cavity side, and piston rod is positioned at the part outside hydraulic cylinder
Installing tooth bar, described rack and pinion is meshed, and ratchet is installed in the side of described gear；Described bar is arranged on below ratchet,
The middle part of bar is arranged on bearing by bearing pin, and one end of bar arranges ratchet, and the bar other end connects small-scale liquid cylinder pressure by bearing pin.
As further program of the utility model: described small-scale liquid cylinder pressure connects small-scale liquid press pump, small-scale liquid press pump connects electricity
Magnetic relay.
As further program of the utility model: the diameter of described piston rod is less than the diameter of hydraulic stem hydraulic stem.
Compared with prior art, the beneficial effects of the utility model are: utilize click structure be capable of hydraulic cylinder with
Shi Zisuo, and the mode of this machine locking to compare hydraulic circuit locking mode relatively reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of hydraulic cylinder self locking apparatus.
Fig. 2 is the structural representation of click locking mechanism in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clearly
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1-2, in this utility model embodiment, a kind of hydraulic cylinder self locking apparatus, including: hydraulic cylinder 1, piston 2,
Piston rod 3, tooth bar 4, gear 5, ratchet 6, small-scale liquid cylinder pressure 7, bearing 8, bar 9 and ratchet 10, described piston
Bar 3 is arranged on piston 2 rodless cavity side, and the part that piston rod 3 is positioned at outside hydraulic cylinder 1 installs tooth bar 4, described tooth bar 4
Being meshed with gear 5, ratchet 6 is installed in the side of described gear 5,；Described bar 9 is arranged on below ratchet 6, in bar 9
Portion is arranged on bearing 8 by bearing pin, and one end of bar 9 arranges ratchet 10, and bar 9 other end connects small-sized hydraulic by bearing pin
Cylinder 7, when hydraulic cylinder 1 is without locking, the hydraulic stem of small-scale liquid cylinder pressure 7 is in the state of stretching out, and ratchet 10 is with ratchet 6 not
Contact, when hydraulic cylinder 1 needs locking, the hydraulic stem of small-scale liquid cylinder pressure 7 reclaims, and band pawl 10 moves upward, and
Contacting with ratchet 6, make ratchet 6 fix, owing to ratchet 6 is fixedly mounted on gear 5, therefore gear 5 is fixed,
Make piston rod 3 fix by tooth bar 4, thus realize hydraulic cylinder 1 self-locking.
Described small-scale liquid cylinder pressure 7 connects small-scale liquid press pump 12, and small-scale liquid press pump 12 connects electromagnetic relay 11, utilizes electromagnetism
Relay 11 controls the motion of small-scale liquid cylinder pressure 7, it is achieved hydraulic cylinder 1 self-locking at any time.
The diameter of described piston rod 3 is less than the diameter of hydraulic stem 1 hydraulic stem, to ensure hydraulic cylinder 1 rod chamber and rodless cavity
Lifting surface area, makes hydraulic cylinder 1 normally to work.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of spirit or essential attributes of the present utility model, it is possible to realize this utility model in other specific forms.
Therefore, no matter from the point of view of which point, all should regard embodiment as exemplary, and be nonrestrictive, this practicality is new
The scope of type is limited by claims rather than described above, it is intended that by the containing of equivalency in claim that fall
All changes in justice and scope are included in this utility model.Should not be considered as any reference in claim limiting
Involved claim.
Although moreover, it will be appreciated that this specification is been described by according to embodiment, but the most each embodiment only comprises
One independent technical scheme, this narrating mode of description is only the most for clarity sake, and those skilled in the art should be by
Description is as an entirety, and the technical scheme in each embodiment can also be through appropriately combined, and forming those skilled in the art can
