Abstract
The utility model discloses a front dual-seal hydraulic oil cylinder of a self-discharging car. The front dual-seal hydraulic oil cylinder comprises a big housing and a big housing cover plate, wherein a small housing is sleeved in the big housing; a big shroud ring structure is arranged on the big housing; and a small shroud ring structure is arranged on the small housing; the front dual-seal hydraulic oil cylinder is characterized in that a primary cylinder barrel, a secondary cylinder barrel, a tertiary cylinder barrel and a quaternary cylinder barrel are sleeved in the small housing in sequence; and two sealing rings and an anti-extruding device are arranged at one end of each of the primary cylinder barrel, the secondary cylinder barrel, the tertiary cylinder and the quaternary cylinder. The front dual-seal hydraulic oil cylinder disclosed by the utility model is reasonable in design, simple in structure and convenient to install; and each of the cylinder barrels is provided with the two sealing rings, so that the sealing performance is preferable.
Description
Technical field:
The utility model relates to a kind of front-mounted self-dumping truck hydraulics field, is specifically related to a kind of front-mounted self-dumping truck double sealing hydraulic jack.
Background technique:
Hydraulic jack is mainly used in various model dump trucks, it adopts single-action telescopic sleeve hydraulic cylinder, and the hydraulic jack that uses at present use is all the single track oil sealing, oil sealing sealing is good not, work under rugged environment and easily cause the damage of seal ring, thereby cause oil cylinder to produce the phenomenons such as cut, reduced oil cylinder to working life.
The model utility content:
The purpose of this utility model is in order to make up the deficiency of prior art, a kind of front-mounted self-dumping truck double sealing hydraulic jack to be provided, so just solved the not strong problem of existing dumping car sealability, greatly having improved the sealability of oil cylinder.
The utility model solution is as follows:
A kind of front-mounted self-dumping truck double sealing hydraulic jack, comprise large shell and large cover plate of outer casing, be set with little shell in described large shell, establish large shroud ring structure on large shell, little shell is established the parcel cuff structure, it is characterized in that: be set with successively the one-level cylinder barrel in described little shell, secondary cylinder barrel and three grades of cylinder barrels, level Four cylinder barrel, described one-level cylinder barrel, the secondary cylinder barrel, an end of three grades of cylinder barrels and level Four cylinder barrel is equipped with two seals circle and anti-extrusion device.
Described two seals circle is respectively dustproof platform and oil sealing, and sealing effect is better.
Described large cover plate of outer casing is provided with erection opening, convenient lifting.
Its working principle is: when oil cylinder was worked, cylinder barrels at different levels were also risen progressively section by section, and timely environment evil slightly second oil sealing also can effectively intercept.
Model utility is reasonable in design, and is simple in structure, and it is convenient to install, lift, and the more effective damage frequency that reduces cylinder barrel has improved product performance greatly.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Wherein: 1, large shell, 2, large cover plate of outer casing, 3, large shroud ring structure, 4, the parcel cuff structure, 5, little shell, 6, the one-level cylinder barrel, 7, the secondary cylinder barrel, 8, three grades of cylinder barrels, 9, dustproof platform, 10, anti-extrusion device, 11, oil sealing, 12, main shaft, 13, erection opening.
