The utility model is the multi-channel hydraulic cylinder, which has the advantages of compact simple, wide application scope, realizing the multi-point independent control, and enhancing the whole efficacy thereof.
Description
Technical field
The utility model is mainly concerned with the hydraulic jack field, refers in particular to a kind of multichannel hydraulic jack.
Background technique
In the prior art, general hydraulic jack all includes only a hydraulic oil control channel, so it also can only finish single function, can not support the different operating of a plurality of executive components simultaneously.With the hoist is example, and the extending means of domestic existing single oil cylinder hoist is to add a hose reel 107 by a telescopic hydraulic cylinder to realize the flexible of arm and provide inserted pin mechanism required dynamicliquid pressure oil.Referring to shown in Figure 1, control by selector valve group 101, oil pressure in the telescopic oil cylinder 102 in the hydraulic oil control channel 103 changes, thereby the operation that piston rod is finished stretch out or withdraw, but it can only support the operation of an executive component, such as the normal pin among the figure 105,106 of horizontal pins can only be controlled by the hydraulic oil that hose reel 107 is introduced.This shows that the defective of the hydraulic jack of single passage just is: can't realize that multiple spot independently controls, otherwise mechanism's complexity, poor reliability is installed inconvenience.
The model utility content
The technical problems to be solved in the utility model just is: at the technical problem of prior art existence, the utility model provide a kind of simple and compact for structure, Applicable scope is wider, can realize that multiple spot independently controls, and improves the multichannel hydraulic jack of its overall efficiency.
For solving the problems of the technologies described above, the solution that the utility model proposes is: a kind of multichannel hydraulic jack, it is characterized in that: it comprises cylinder body and is installed in the interior main piston rod of cylinder body, offer filler opening and oil outlet on the main piston rod, form between filler opening and the oil outlet in the cylinder body and led oily passage, be provided with one or more nested successively sleeve pipes in the described cylinder body, be equipped with piston rod in each sleeve pipe, all offer sleeve pipe filler opening and sleeve pipe oil outlet on each sleeve pipe, formed oily passage between cover inner casing tube filler opening and the sleeve pipe oil outlet.
Described sleeve pipe comprises first sleeve pipe and second sleeve pipe, first sleeve pipe and second sleeve pipe are fixed in the first end of bar of main piston rod, be equiped with the first piston bar in first sleeve pipe, be equiped with second piston rod on second sleeve pipe, the first piston bar and second piston rod are fixed in cylinder bottom one end of cylinder body, and the inner chamber of first sleeve pipe and second sleeve pipe formed oily passage.
Compared with prior art, advantage of the present utility model just is: the utility model is simple and compact for structure, Applicable scope is wider, by making full use of the space of telescopic hydraulic cylinder piston rod cavity or inner chamber of cylinder block, increase a plurality of oily passages of independently crossing, thereby realize that multiple spot independently controls, improved the overall efficiency of oil cylinder, after installing structure of the present utility model on the complete machine, not only can simplify the structure of complete machine, reduce cost, can also improve the level of integration and the validity of control mechanism.

Embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details.
As shown in Figures 2 and 3, multichannel hydraulic jack of the present utility model, it comprises cylinder body 1 and the main piston rod 2 that is installed in the cylinder body 1, offer filler opening 3 and oil outlet 4 on the main piston rod 2, form between filler opening 3 and the oil outlet 4 in the main piston rod 2 and led oily passage 5, be provided with one or more nested successively sleeve pipes 6 in the described cylinder body 1, be equipped with piston rod 7 in each sleeve pipe 6, all offer sleeve pipe filler opening 8 and sleeve pipe oil outlet 9 on each sleeve pipe 6, formed oily path 10 between sleeve pipe 6 inner sleeve filler openings 8 and the sleeve pipe oil outlet 9, and a plurality ofly independently crossed oily path 10 separately and led oily passage 5 and realize that multiple spots independently control thereby utilize.In the present embodiment, sleeve pipe 6 comprises first sleeve pipe 11 and second sleeve pipe 12, first sleeve pipe 11 and second sleeve pipe 12 are fixed in the first end of bar of main piston rod 2, be equiped with first piston bar 13 in first sleeve pipe 11, be equiped with second piston rod 14 on second sleeve pipe 12, the first piston bar 13 and second piston rod 14 are fixed in cylinder bottom one end of cylinder body 1, and the inner chamber of first sleeve pipe 11 and second sleeve pipe 12 formed oily path 10.When telescopic hydraulic cylinder rodless cavity oil-feed cylinder barrel stretches out (driving the arm motion), first sleeve pipe 11 and second sleeve pipe 12 are with movement therewith, simultaneously, the inner chamber of first sleeve pipe 11 and second sleeve pipe 12 is as the oily path 10 of the mistake of two other oil circuit (a-a1 and b-b1 among the figure).Because the piston between each oil circuit is all selected the Sealing of two way sealed for use, thereby guarantees can not gang up between each oil circuit, use reliable.Referring to Fig. 2, with structure applications of the present utility model in the extending means of single oil cylinder hoist the time, led oily passage 5 (A-A1) oil-feed, cylinder body 1 stretches out, be fixed on first sleeve pipe 11 of cylinder body 1 bottom and second sleeve pipe 12 simultaneously along with cylinder body 1 motion, at this moment, another executive component of hoisting arm expansion mechanism--inserted pin mechanism, can from the oil circuit of crossing oily path 10 (a-a1 and b-b1), obtain the required dynamicliquid pressure oil of work, this shows, utilize the space of telescopic hydraulic cylinder piston rod cavity, increase by two oily passages of mistake, the cancellation hose reel, directly offer the required dynamicliquid pressure oil of inserted pin mechanism from telescopic hydraulic cylinder, not only can simplify the internal structure of an organization, be convenient to install, can also reduce the rate of fault of extending means.
