Abstract
The utility model discloses an anti-corrosion overflow barrel hydraulic cylinder. The anti-corrosion overflow barrel hydraulic cylinder comprises a cylinder barrel, a guide sleeve, a connecting flange fixedly connected with the cylinder barrel, a piston rod, a piston fixedly connected with the piston rod, a rod cavity hydraulic fluid port and a rodless cavity hydraulic fluid port, and is characterized in that a flange is fixedly connected with the piston rod outside the cylinder barrel; a protective sleeve is arranged outside the cylinder barrel; the protective sleeve is connected with the flange through a plurality of screws; a sealing ring is arranged between the protective sleeve and the cylinder barrel. The anti-corrosion overflow barrel hydraulic cylinder has the advantages of low cost and convenience in maintenance and replacement.
Description
Technical field
The utility model relates to a kind of oil hydraulic cylinder, especially for the overflow cylinder oil hydraulic cylinder of rake suction boats and ships.
Background technique
Overflow cylinder oil hydraulic cylinder is mainly used in harrowing the motion that suction boats and ships are got rid of seawater in the process that stores mud.What overflow cylinder oil hydraulic cylinder adopted at present is that piston rod is fixed, and cylinder barrel slides at piston rod surface; Because seawater has strong corrosive action, therefore cylinder barrel material adopts stainless steel material, cause manufacture cost higher more, and in the time that cylinder barrel corrosion need to be changed, oil hydraulic cylinder need to be peeled off out from boats and ships, changed by professional person; Not only increase maintenance cost, and the delay boats and ships operating time.
Model utility content
The purpose of this utility model is for prior art above shortcomings, and a kind of corrosion protection overflow cylinder oil hydraulic cylinder is provided, and it has advantages of, and cost is relatively low, convenient maintenance and replacement.
For achieving the above object; a kind of corrosion protection overflow cylinder oil hydraulic cylinder of the present utility model; comprise cylinder barrel, guide sleeve, be fixed on connecting flange, the piston rod on cylinder barrel and be fixed on piston, rod chamber hydraulic fluid port and the rodless cavity hydraulic fluid port on piston rod; it is characterized in that being fixedly connected with flange plate on the piston rod outside cylinder barrel; be provided with protecting jacket outward at cylinder barrel; protecting jacket and flange plate are connected by several screws, between protecting jacket and cylinder barrel, are provided with seal ring.
Protecting jacket of the present utility model separates cylinder barrel and seawater, corrosion be protecting jacket, prevent the corrosion of seawater to cylinder barrel, cost is relatively low, and protecting jacket and cylinder barrel can be movable relatively, and does not affect the normal work of cylinder barrel; In the time that needs are changed protecting jacket, only need screw to back out;
As further improvement of the utility model, described flange plate by with piston rod on the step that fastens and be located at back-up ring and the solid rod joint in piston rod annular groove; Be convenient to the maintain and replace of flange plate and protecting jacket;
In sum, the utlity model has that cost is relatively low, the advantage of convenient maintenance and replacement.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's plan view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1; this corrosion protection overflow cylinder oil hydraulic cylinder; comprise that cylinder barrel 1, guide sleeve 2, welding are fixed on connecting flange 3, the piston rod 4 on cylinder barrel 1 and are fixed on piston 5 on piston rod 4, are located at the interior rod chamber hydraulic fluid port 6 of piston rod 4 and rodless cavity hydraulic fluid port 7; on piston rod 4 outside cylinder barrel 1, be fixedly connected with flange plate 9 by the step fastening with piston rod 4 and the back-up ring 8 of being located in piston rod annular groove; outside cylinder barrel 1, be provided with protecting jacket 10; protecting jacket 10 is connected by several screws with flange plate 9, between protecting jacket 10 and cylinder barrel 1, is provided with seal ring 11.
Protecting jacket 10 of the present utility model separates cylinder barrel 1 and seawater, what corrode is protecting jacket 10, prevent the corrosion of seawater to cylinder barrel 1, cost is relatively low, cylinder barrel 1 is outer also can chromium plating improve anti-corrosive properties, and protecting jacket 10 can be movable relatively with cylinder barrel 1, in the time of 7 oil-feed of rodless cavity hydraulic fluid port, it is overhanging that fluid promotes cylinder barrel 1, make the overflow mechanism being connected on flange 3 leave hull, seawater and silt leak into deep-sea, when 6 oil-feeds of rod chamber hydraulic fluid port, cylinder barrel 1 is retracted under pressure, the seawater and the silt that are attached to cylinder barrel 1 surface are peeled off cylinder barrel outer surface by protecting jacket 10, seal ring 11 prevents that seawater from entering inside simultaneously, in the time that needs are changed protecting jacket 10 or flange plate 9, only need to dismantle back-up ring 8 or screw is backed out, the utlity model has that cost is relatively low, the advantage of convenient maintenance and replacement.
Claims (2)
1. a corrosion protection overflow cylinder oil hydraulic cylinder; comprise cylinder barrel, guide sleeve, be fixed on connecting flange, the piston rod on cylinder barrel and be fixed on piston, rod chamber hydraulic fluid port and the rodless cavity hydraulic fluid port on piston rod; it is characterized in that being fixedly connected with flange plate on the piston rod outside cylinder barrel; be provided with protecting jacket outward at cylinder barrel; protecting jacket and flange plate are connected by several screws, between protecting jacket and cylinder barrel, are provided with seal ring.
