The present invention relates to a kind of Hydraulic Elements, particularly to a kind of Quick-pressurizing oil cylinder.

(2) background technology

Dual-active Hydraulic Cylinder be widely used in various mechanically, currently used Hydraulic Cylinder, its inner carrier is single-casting, Inner carrier oil-in and main hydraulic fluid port are all on cylinder body, and inner carrier oil-in is positioned at below main hydraulic fluid port, on inner carrier big end cylindrical Have oil ring groove, in annular groove, have oilhole to communicate with inner carrier thin rod part center oilhole.Inner carrier is contained in cylinder body, uses screw plug Compress, plug end face is installed replenishing valve.The external force of the speed of service of this oil cylinder and oil cylinder output is single, the machinery effect of oil cylinder Rate is low, and energy consumption is high.

(3) summary of the invention

The present invention is in order to make up the defect of prior art, it is provided that the Quick-pressurizing oil cylinder that a kind of mechanical efficiency is high, energy consumption is low.

The present invention is achieved through the following technical solutions:

A kind of Quick-pressurizing oil cylinder, including cylinder bottom, inner cylinder tube, outer cylinder, inner carrier, outer piston, piston rod, oil nozzle one and oil nozzle Two, it is characterized in that, described piston rod is positioned at inner cylinder tube, and also and the fixing connection of inner carrier, described outer piston and inner cylinder tube are fixing even Connecing, inner cylinder tube is divided into interior left oil pocket and interior right oil pocket by inner carrier, and outer cylinder is divided into outer left oil pocket and outer right oil pocket by outer piston, Described oil nozzle one is communicated with outer left oil pocket by oil pipe, and oil nozzle two communicates with outer right oil pocket, and described outer piston right-hand member is provided with oil-feed Groove, is provided with some oilholes bottom described oil-feed tank, outer left oil pocket is connected by described oilhole with oil-feed tank, bottom oil-feed tank on wear Have valve rod, valve rod right-hand member be outer thick in the thin frustum of a cone the frustum of a cone be positioned at left oil pocket, oil-feed tank can be blocked by the frustum of a cone, Valve rod left end is positioned at outer left oil pocket and is cased with spring, and the left end of spring and the left end of valve rod connect.

Described outer piston and inner cylinder tube junction are cased with Reinforced Hoop.

The left end of described piston rod is positioned at left oil pocket and threaded has nut.

The invention has the beneficial effects as follows:

The sectional area of inner cylinder tube is little, and in the case of same flow system pumping plant, the speed of service can be more several times greater than outer cylinder;Outer shell The sectional area of cylinder is big, and in the case of same pressure system pumping plant, the outer force rate inner cylinder tube of oil cylinder output turns over several times.The present invention is abundant Utilize above-mentioned principle, by the conversion of valve rod, in making cylinder efficient run, realize the when that load being little quickly running;Load becomes Moment supercharging time big, overcomes resistance, substantially increases mechanical efficiency, reduce energy consumption.

(4) accompanying drawing explanation

The present invention is further illustrated below in conjunction with the accompanying drawings:

Fig. 1 is the sectional structure schematic diagram of the present invention.

In figure, 1 cylinder bottom, 2 inner cylinder tubes, 3 outer cylinders, 4 inner carriers, 5 outer pistons, 6 piston rods, 7 oil nozzles one, 8 oil nozzles two, 9 Interior left oil pocket, right oil pocket in 10,11 outer left oil pockets, 12 outer right oil pockets, 13 Reinforced Hoop, 14 oil pipes, 15 oil-feed tanks, 16 oilholes, 17 Valve rod, 171 frustums of a cone, 18 springs, 19 nuts.

(5) detailed description of the invention

Accompanying drawing is the specific embodiment of the present invention.As it is shown in figure 1, this kind of Quick-pressurizing oil cylinder, including cylinder bottom 1, inner cylinder tube 2, outer Cylinder barrel 3, inner carrier 4, outer piston 5, piston rod 6, oil nozzle 1 and oil nozzle 28, inner cylinder tube 2 is divided into interior left oil pocket 9 by inner carrier 4 With interior right oil pocket 10, outer cylinder 3 is divided into outer left oil pocket 11 and outer right oil pocket 12 by outer piston 5, and piston rod 6 is positioned at inner cylinder tube 2, The left end of piston rod 6 is through in stretching into interior left oil pocket 9 after inner carrier 4 and threaded coupling nut 19, and the right-hand member of piston rod 6 is from outward Cylinder barrel 3 stretches out, outer piston 5 and the fixing connection of inner cylinder tube 2, and its junction is cased with Reinforced Hoop 13, and oil nozzle 1 passes through oil pipe 14 with outer Left oil pocket 11 communicates, and oil nozzle 28 communicates with outer right oil pocket 12, and outer piston 5 right-hand member has dug oil-feed tank 15, the mouth of oil-feed tank 15 to the left For circle, the outside left oil pocket 11 in bottom of oil-feed tank 15 opens six oilholes 16, and these oilholes 16 are by outer left oil pocket 11 and oil-feed Groove 15 is connected, bottom oil-feed tank 15 on be installed with a valve rod 17, valve rod 17 right-hand member be outer thick in thin the rightest thick left the thinnest The frustum of a cone 171, this frustum of a cone 171 is positioned at left oil pocket 9, and oil-feed tank 15 can be blocked by the frustum of a cone 171, the left end of valve rod 17 Being positioned at outer left oil pocket 11 and be cased with spring 18, the left end of spring 18 and the left end of valve rod 17 connect.

Work process is as follows: when pressure oil enters outer left oil pocket 11 by oil nozzle 1, pressure oil is entered by oilhole 16 The frustum of a cone 171 is also pushed away the notch of oil-feed tank 15 by oil-feed tank 15, and pressure oil enters interior left oil pocket 9 from oil-feed tank 15, in promoting Piston 4 and piston rod 6 quickly run;If running into bigger load in running, the pressure in inner cylinder tube 2 there being pressure is rapid Raising, exceed system pressure, now valve rod 17 is pressed within and promotes to left movement, and the notch of oil-feed tank 15 is closed by the frustum of a cone 171, Inner cylinder tube 2 moment quits work, and now acts on outer piston 5, due to the work of outer piston 5 in the most left oil pocket of system pressure oil 11 Increasing with area, the external force making oil cylinder export increases, it is achieved supercharging, overcomes bigger load, piston rod 6 to continue to run to the right; If load reduces suddenly in running, valve rod 17 moves right again to be opened oil-feed tank 15, and pressure oil enters interior left oil pocket 9, Promoting inner carrier 4 to drive piston rod 6 to move on, outer piston 5 stops, it is achieved quickly running simultaneously

In addition to technical characteristic described in description, remaining technical characteristic is all known to a person skilled in the art technology.
