Abstract
A kind of antipollution oil cylinder, comprising：The cylinder barrel and cylinder rod of relative movement can be produced, also comprising the protection cylinder being set on cylinder barrel, one end of protection cylinder is fixed in cylinder rod, and the wall contacts of the other end and cylinder barrel set seal assembly between cylinder barrel and protection cylinder.The utility model is when oil cylinder is arranged in the more severe pollution environment of operating mode; the cylinder rod of oil cylinder not contact stain thing can be protected; the oil cylinder life-span for preventing cylinder seal from failing and producing reduces problem, it is ensured that the cleannes of cylinder efficient environment, effectively ensure that the service life of oil cylinder.
Description
Technical field
The utility model is related to a kind of antipollution oil cylinder.
Background technology
At present, in coal mine machinery application field, because the working environment of oil cylinder in mine is more severe, mud, building stones etc.
It is difficult to clean up, the cylinder rod of oil cylinder is generally exposed in working environment, is worked under the contact environment of various materials, therefore cylinder rod
Can often occur colliding with scar, grind etc., make the seal failure of oil cylinder, reduce the service life of oil cylinder.
Utility model content
The utility model provides a kind of antipollution oil cylinder, can when oil cylinder is arranged in the more severe pollution environment of operating mode
To protect the cylinder rod of oil cylinder not contact stain thing, the oil cylinder life-span for preventing cylinder seal from failing and producing reduces problem, it is ensured that
The cleannes of cylinder efficient environment, effectively ensure that the service life of oil cylinder.
In order to achieve the above object, the utility model provides a kind of antipollution oil cylinder, comprising：The cylinder of relative movement can be produced
Cylinder and cylinder rod, also comprising the protection cylinder being set on cylinder barrel, one end of protection cylinder is fixed in cylinder rod, the other end and cylinder barrel
Wall contacts.
Seal assembly is set between described cylinder barrel and protection cylinder.
Described seal assembly uses asbestos packing.
Described protection cylinder is contacted by guide pad with cylinder barrel.
Described protection cylinder is bolted in cylinder rod.
Described cylinder rod is used as mobile terminal as fixing end, described cylinder barrel.
The oil inlet and oil-out of described antipollution oil cylinder are all disposed within cylinder rod one end, enter oil road and are all drawn by cylinder rod
Go out.
The utility model can protect the cylinder rod of oil cylinder not connect when oil cylinder is arranged in the more severe pollution environment of operating mode
Pollutant is touched, the oil cylinder life-span for preventing cylinder seal from failing and producing reduces problem, it is ensured that the cleannes of cylinder efficient environment,
It effectively ensure that the service life of oil cylinder.
Brief description of the drawings
Fig. 1 is the cylinder barrel and the front sectional view of cylinder rod for a kind of antipollution oil cylinder that the utility model is provided.
Fig. 2 is a kind of vertical view cutaway drawing of the protection barrel structure for antipollution oil cylinder that the utility model is provided.
Embodiment
Below according to Fig. 1 and Fig. 2, preferred embodiment of the present utility model is illustrated.
As depicted in figs. 1 and 2, the utility model provides a kind of antipollution oil cylinder, comprising：Cylinder barrel 1 and cylinder rod 2, cylinder barrel 1 with
Cylinder rod 2 produces relative movement under hydraulic oil effect, and protection cylinder 4 is set on cylinder barrel 1, and its one end is fixed on cylinder by bolt 3
On bar 2, the other end of cylinder 4 is protected by guide pad 5 and the wall contacts of cylinder barrel 1, when cylinder barrel 1 is acted on cylinder rod 2 in hydraulic oil
During lower generation relative movement, relative slip is produced between the guide pad 5 and cylinder barrel 1 on protection cylinder 4, is led between cylinder barrel 1 and protection cylinder 4
Cross seal assembly 6 (using asbestos packing in the present embodiment) to be sealed, so form the piston rod working seal of a cleaning
Cavity, when oil cylinder is arranged in the more severe pollution environment of operating mode, can protect the cylinder rod of oil cylinder not contact stain thing, prevent
The oil cylinder life-span that cylinder seal fails and produced reduces problem, it is ensured that the cleannes of cylinder efficient environment, effectively ensure that oil
The service life of cylinder.
Described cylinder rod 2 is as fixing end, and described cylinder barrel 1 is as mobile terminal, and the oil pipe arrangement of oil cylinder is moved without considering
The stroke change of movable property life.
The oil inlet and oil-out 7 of oil cylinder are all disposed within the one end of cylinder rod 2, enter oil road and are all drawn by cylinder rod, so may be used
To ensure that cylinder barrel outer face is circular configuration, it is easy to arrangement annulus sealing.
Although content of the present utility model is discussed in detail by above preferred embodiment, but it should be appreciated that on
The description stated is not considered as to limitation of the present utility model.After those skilled in the art have read the above, for
A variety of modifications and substitutions of the present utility model all will be apparent.Therefore, protection domain of the present utility model should be by appended
Claim limit.
