Limitation.
The utility model discloses a kind of load lifting cylinder, and having includes cylinder body 4 and piston rod 5, and 5 one end of piston rod forms work
Plug 6, is slidably set in cylinder body 4, and seals (closed) between piston 6 and the inner wall of cylinder body 4, and 4 inner cavity of cylinder body is divided into that
This independent first chamber 41 and the second chamber 42.The other end of piston rod 5 exposes from cylinder body 4.
Then, the load lifting cylinder of the utility model further includes the first pipeline 1, the second pipeline 2 and third pipeline 3, wherein first
Pipeline 1 is connected to the first chamber 41, and the second pipeline 2 is connected to the second chamber 42, and the both ends of third pipeline 3 are respectively communicated with the first chamber 41 and second
Chamber 42；Solenoid valve 7 is provided on third pipeline 3.
Load lifting cylinder can be hydraulic cylinder, be also possible to pneumatic cylinder, corresponding above-mentioned first pipeline 1, the second pipeline 2 and third
Pipeline 3 can be for dredging hydraulic oil, be also possible to for dredging gas (high pressure gas).For convenience of explanation, this specification with
Illustrate for hydraulic cylinder.It is to be understood that the hydraulic oil (gas) in the first pipeline 1 and the second pipeline 2 be by pump 8 provide, but
It is that the pump 8 can be in the prior art for hydraulic any pump kind.
First pipeline 1 can be to the first chamber 41 for hydraulic oil, and can also be flows back to hydraulic oil from the first chamber 41.It is corresponding
The second pipeline 2 can be to the second chamber 42 for hydraulic oil, can also be flows back to hydraulic oil from the second chamber 42.
In specific two cavitys which for the first chamber 41, which is the second chamber 42, which closes road 1 for first, which is the
Two pipelines 2 are arranged according to different situations, the application merely for convenience of description, the name carried out to it.As shown, with
The chamber of one end far from the exposing of piston rod 5 is the first chamber 41, another is the second chamber 42.That corresponding first pipeline 1 and second
Pipeline 2 is also easy for distinguishing.
In use, the first pipeline 1 is to 41 fuel feeding of the first chamber, then 41 space of the first chamber becomes larger, and pushes the piston movement, piston
Bar 5 slides in and out.Oil in second chamber 42 can be flowed out along the second pipeline 2.It is corresponding, the second pipeline 2 to 42 fuel feeding of the second chamber,
Second chamber 42 becomes larger, and compresses the space of the first chamber 41, and piston rod 5 shrinks, that is, moves inward, and the oil in the first chamber 41 is along the
The outflow of one pipeline 1.
Third pipeline 3 is connected to the first chamber 41 and the second chamber 42, when carrying out the operation of the above-mentioned movement of piston rod 5, that is,
When first pipeline 1 or the second pipeline 2 carry out fuel feeding, third pipeline 3 is disconnected, that is, is disconnected by solenoid valve 7, and 41 He of the first chamber is made
Second chamber 42 is not connected to.The mobile operation of piston rod 5 at this time refers to needs, and it plays the role of pushing and pressing, and the operation supported can also
To be called lift operation.Such as its be used for truck cap overturning when, in the case where needing to overturn driver's cabin, it is necessary to be living
Stopper rod 5 is mobile, to guarantee the motion profile of driver's cabin, and fixed upturned position.
And when not needing to carry out above-mentioned mobile, solenoid valve 7 control the first chamber 41 and the second chamber 42 conducting, make two it is intracavitary
Hydraulic oil be in equilibrium state, make this entire load lifting cylinder be in have damping force in the state of.It is, load lifting cylinder is being not required to
When carrying out lift operation, it can be used as simple damper and use.It, can such as in the connection for driver's cabin and vehicle frame
It avoids playing the role of bradyseism for driver's cabin.
Preferably, the first connecting pin 43 is provided on the outside of cylinder body 4, piston rod 5 forms second from one end that cylinder body 4 exposes and connects
Connect end 51.The two connecting pins can be convenient it and install and use.
A kind of driver's cabin lifting mechanism is also disclosed in the utility model, including：Above-mentioned load lifting cylinder, and pump 8；First pipeline
1 and second pipeline 2 be connected to respectively with pump 8, which makes the first pipeline 1 and the second pipeline 2, can carry out fuel feeding and oil return respectively
Operation.Pump 8 is fixed on vehicle frame 91；Cylinder body 4 is rotationally connect with vehicle frame 91, and piston rod 5 rotationally connects with driver's cabin 92
It connects.
Further include：Turnover mechanism 93 and rear support 94, they have fixing end and movable end, their fixing end respectively
It is all disposed on vehicle frame 91, movable end connects driver's cabin 92.It further, should also include the equipment controlled solenoid valve 7, it can
To be arranged in driver's cabin 92, or by the electronic system automatic control of vehicle.It is shown in dotted line in Fig. 2 that solenoid valve 7 is controlled
Route 71, can be the route of entity, be also possible to wireless signal.One end of route 71 is connected to pump 8 in Fig. 2,
It, only as an example, not necessarily indicate by 8 control solenoid valves 7 of pump, does not negate that pump 8 may be implemented to solenoid valve 7 certainly yet
Control, after all when pump 8 determines the first pipeline 1 or the second 2 fuel feeding of pipeline, solenoid valve 7 is to close third pipeline 3
's.
In the utility model driver's cabin lifting mechanism, it is preferred that one section of idle stroke is set inside the cylinder body 4 of load lifting cylinder and is used
It jolts together fluctuation in driver's cabin 92, passes through the on-off that solenoid valve 7 controls oil circuit in idle stroke.The idle stroke is usually piston
Bar 5 moves in the range of idle stroke, and lift operation can't be carried out to driver's cabin 92, only provides buffer capacity.
The structure, features, and effects of the present invention is described in detail based on the embodiments shown in the drawings, with
Upper described is only the preferred embodiment of the utility model, but the present invention does not limit the scope of implementation as shown in the drawings, it is all according to
