Abstract
The utility model discloses a control type hydrocylinder, which belongs to the technical field of hydrocylinders. The control type hydrocylinder comprises a control valve part, an oil cylinder part and a flange, wherein the control valve part is installed at the top of the oil cylinder part through the flange. The control type hydrocylinder provided by the utility model can realize the organic combination of the control valve and the oil cylinder, and has the advantages of small volume, simple structure and good reliability, thereby having wide market prospect.
Description
Technical field
The utility model relates to a kind of control type hydraulic jack, belongs to technical field of hydraulic oil cylinder.
Background technique
In the prior art, the control oil cylinder in the hydraulic system of hydraulic pile hammer, most of mode that adopts oil cylinder and control valve to be installed separately; Though the structure that also has small part to adopt oil cylinder and control valve to be fitted together, but be the adhesion type structure, and in order to lower the center of gravity, control valve always is positioned at the oil cylinder bottom, link to each other with oil cylinder by the large diameter oil pipe of high pressure, sometimes even need the multiple-tubing string parallel connection to satisfy the big fluence requirement of high pressure.Above-mentioned which kind of structure no matter exists all that volume is big, the problem of complex structure, poor reliability.
How to overcome the above-mentioned deficiency of existing control type hydraulic jack, become the technical barrier that those skilled in the art need to be resolved hurrily.
Summary of the invention
The utility model is intended to propose a kind of novel control type hydraulic jack, and it has overcome above-mentioned deficiency by structural improvement, realizes the combination of control valve and oil cylinder, and possesses plurality of advantages such as volume is little, simple in structure, good reliability.
This control type hydraulic jack mainly comprises: control valve part, oil cylinder part and flange, described control valve part is installed in the top of described oil cylinder part by described flange.
Preferably, described oil cylinder partly comprises inner cylinder tube, outer cylinder, piston, piston rod, oil duct and filler opening, and described oil duct is formed between described inner cylinder tube and the outer cylinder, and described filler opening is located on the described outer cylinder.
Preferably, described control valve partly comprises valve seat, the first Electromagnetic Control spool, the second Electromagnetic Control spool, cavity and oil outlet, described cavity is located on the described valve seat, corresponding with described oil duct, described first Electromagnetic Control spool and oil outlet are located at the side of described cavity, and the described second Electromagnetic Control spool is located at the top of described cavity.
Compared to prior art, control type hydraulic jack of the present utility model is owing to the combination that has realized control valve and oil cylinder, thereby volume is little, simple in structure, good reliability.
Description of drawings
Fig. 1: the structural representation of control type hydraulic jack of the present utility model.
Symbol description: 1, control valve part; 2, oil cylinder part; 3, valve seat; 4, inner cylinder tube; 5, outer cylinder; 6, oil duct; 7, piston rod; 8, filler opening; 9, piston; 10, flange; 11, the first Electromagnetic Control spool; 12, oil outlet; 13, the second Electromagnetic Control spool; 14, cavity.
Embodiment
Below in conjunction with accompanying drawing, describe the structure of control type hydraulic jack of the present utility model and form.
As shown in Figure 1, this control type hydraulic jack mainly comprises: control valve part 1, oil cylinder part 2 and flange 10, control valve part 1 is installed in oil cylinder part 2 tops by flange 10.Wherein:
During work, hydraulic oil enters oil duct 6 between oil cylinder inner cylinder tube 4, the outer cylinder 5 by filler opening 8, if the second Electromagnetic Control spool 13 is opened, the first Electromagnetic Control spool 11 is closed, and the piston rod 7 in the moving oil cylinder part 2 of hydraulic oil thruster moves downward; If the second Electromagnetic Control spool 13 is closed, the first Electromagnetic Control spool 11 is opened, and hydraulic oil is discharged by oil outlet 12, and the piston rod 7 in the oil cylinder part 2 moves upward.
With way of example the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any change or modification of doing based on the utility model all belong to the claimed scope of the utility model.
