Description
Technical field
The utility model is related to a kind of oil cylinders, and in particular to a kind of sky lift fly jib oil cylinder.
Background technology
The fly jib oil cylinder used on sky lift at present makes since inside guiding is not achieved apart from too short and piston seal performance
With requiring, there are quality problems caused by being fallen after rise after cylinder barrel draws cylinder, piston rod stretches out etc. in use.To improve
Stability, pressurize, the reduction failure rate of oil cylinder in use, are badly in need of reasonably optimizing oil cylinder internal structure.
Invention content
The purpose of this utility model be to provide it is a kind of it is simple in structure, pressurize is good, sky lift fly jib with long service life oil
Cylinder.
To achieve the above object, the technical solution adopted in the utility model is：A kind of sky lift fly jib oil cylinder, including cylinder
Body, piston rod, piston, balanced valve, big chamber oil pipe and small chamber oil pipe, the cylinder interior is hollow, by being located at cylinder interior most
The piston of left end is equipped with piston rod, and left and right ends are respectively equipped with one group of support ring, two groups of branch on the outer wall of the piston
Combined seal ring is installed, the balanced valve is mounted at the top of cylinder body the position that keeps left, the balanced valve left end installation between pushing out ring
There are the big chamber oil pipe being connected with cylinder body, right end that the small chamber oil pipe being connected with cylinder body is installed.
By adopting the above-described technical solution, the utility model has the advantages that：The utility model cylinder strength
It improves, piston guide enhancing, static seal performance enhancement, oil cylinder fall stationarity after rise and improves；General Promotion oil cylinder service life,
It ensure that quality stability, reliability.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
In figure：1, cylinder body, 2, piston rod, 3, piston, 4, balanced valve, 5, big chamber oil pipe, 6, small chamber oil pipe, 7, support ring,
8, combined seal ring.
Specific implementation mode
As shown in Figure 1, the utility model includes cylinder body 1, piston rod 2, piston 3, balanced valve 4, big chamber oil pipe 5 and small chamber oil
Pipe 6,1 inner hollow of the cylinder body, by being equipped with piston rod 2 positioned at the piston 3 of 1 inside left end of cylinder body, the piston 3
Left and right ends are respectively equipped with one group of support ring 7 on outer wall, and combined seal ring 8 is equipped between two groups of support rings 7, described flat
Weighing apparatus valve 4 is mounted at the top of cylinder body 1 position that keeps left, and 4 left end of the balanced valve is equipped with the big chamber oil pipe 5 being connected with cylinder body 1, right
End is equipped with the small chamber oil pipe 6 being connected with cylinder body 1.
With the above arrangement, the operation principle of the utility model is as follows：The utility model increases twice branch on piston 3
Pushing out ring 7, piston, which seals, replaces with the combined type packing ring 8 of static seal superior performance, balanced valve 4 be fixed on cylinder body 1 and with big chamber
Oil pipe 5, the connection of small chamber oil pipe 6, hydraulic oil can realize that the stretching of piston rod 2, contracting act through balanced valve, and the utility model is in structure
Reach simple, compact and ensures service life.
The above content is combine specific preferred embodiment to detailed description made by the utility model, and it cannot be said that originally
The specific implementation mode of utility model is confined to these explanations.For the ordinary skill people of the utility model technical field
For member, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, all should be considered as
Belong to the scope of patent protection that claims that the utility model is submitted determine.
