Abstract
The invention relates to a hydraulic cylinder device. The hydraulic cylinder device comprises a hydraulic cylinder, a cylinder lever and a cylinder cover fixedly connected to the two ends of the hydraulic cylinder, wherein the cylinder lever penetrates through the cylinder cover, and is in sliding connection with the cylinder cover; an outer wall of the cylinder lever comprises a piston integrated with the cylinder lever, and an outer wall of the piston is connected to a seal ring; the cylinder lever comprises a cooling through hole. The hydraulic cylinder device provided by the invention has a simple structure, and compared with the cooling manner of the traditional hydraulic cylinder, the hydraulic cylinder device has the advantages of good cooling effect, long service life and stable running.
Description
Technical field
The present invention relates to hydraulic equipment field, particularly oil hydraulic cylinder.
Background technique
Oil hydraulic cylinder mostly adopts nitrile butadiene rubber as Sealing, its operating temperature can not exceed the operating temperature range of nitrile butadiene rubber, otherwise, while at high temperature work, Sealing easily glutinousization is deadlocked, and after the lower hardness of Sealing, the phenomenon of clamp-oning gap is more serious, and then accelerate it and damage, destroy sealing effect.Therefore need oil hydraulic cylinder to take cooling method, traditional oil hydraulic cylinder type of cooling is asbestos wall to be set around oil hydraulic cylinder protect, and reduces the impact of thermal source on oil hydraulic cylinder.The shortcoming of this mode is that operation is cumbersome, and along with the prolongation of time, cooling effect variation.
Summary of the invention
The applicant, for the above-mentioned shortcoming of the type of cooling of conventional cylinder, studies and improves, and a kind of hydraulic cylinder device is provided, and it has simple in structure, good cooling results, the feature of long service life.
In order to solve the problems of the technologies described above, the present invention adopts following technological scheme:
A kind of hydraulic cylinder device, comprise oil hydraulic cylinder, cylinder bar and the cylinder cap being fixedly connected with oil hydraulic cylinder two ends, it is characterized in that: described cylinder bar is through described cylinder cap, and be slidably connected with described cylinder cap, the outer wall of described cylinder bar comprises the piston with cylinder bar one, and the outer wall of described piston connects seal ring, and described cylinder bar has cooling through hole.
Technique effect of the present invention is:
The present invention is simple in structure, and relatively the type of cooling of conventional cylinder, has good cooling results, long service life and the advantage operating steadily.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
See Fig. 1, the present invention includes oil hydraulic cylinder 1, cylinder bar 3 and the cylinder cap 2 being fixedly connected with oil hydraulic cylinder 1 two ends, cylinder bar 3 passes cylinder cap 2, and is slidably connected with cylinder cap 2, the outer wall of cylinder bar 3 has the piston 5 with cylinder bar 3 one, the outer wall of piston 5 connects seal ring 6, and cylinder bar 3 has cooling through hole 4, and cooling liquid passes into from cooling through hole 4, cylinder bar 3 is carried out cooling, therefore reduced the operating temperature of seal ring 6 simultaneously.
Claims (1)
1. a hydraulic cylinder device, comprise oil hydraulic cylinder, cylinder bar and the cylinder cap being fixedly connected with oil hydraulic cylinder two ends, it is characterized in that: described cylinder bar is through described cylinder cap, and be slidably connected with described cylinder cap, the outer wall of described cylinder bar comprises the piston with cylinder bar one, and the outer wall of described piston connects seal ring, and described cylinder bar has cooling through hole.
