Abstract

The utility model discloses a sequential-action hydraulic cylinder, and relates to the technical field of hydraulic transmission equipment. The sequential-action hydraulic cylinder comprises a cylinder body, an upper cover plate, a lower cover plate, a piston and a piston rod, wherein the upper cover plate and the lower cover plate are arranged at the upper end and the lower end of the cylinder body respectively, oil holes are formed in the upper cover plate and the lower cover plate respectively, the piston is located in the cylinder body, and the piston rod is arranged on the piston. The sequential-action hydraulic cylinder is characterized in that an oil-control opening is formed in the upper cover plate, and one-way valves are arranged on the oil-control opening and the piston respectively. The sequential-action hydraulic cylinder is simple in structure and can achieve sequential actions of an executer through control of the turn-on and turn-off angle of the next-stage executer.

Description

The sequentially-operating oil hydraulic cylinder
Technical field:
The utility model relates to the hydraulic transmission equipment technical field, specifically the sequentially-operating oil hydraulic cylinder.
Background technique:
Hydraulic transmission is to using liquid to realize the technology of transformation of energy, transmission and control by various hydraulic element as working medium .It as one of the key technology of modern transmission and control to be widely used in various mechanized equipments.Existing hydraulic cylinder structure is comparatively single, generally can only realize simple action, can not realize sequentially-operating, and what existing oil hydraulic cylinder had can be the Xi'an sequentially-operating after improvement, but effect is bad.
The model utility content:
The sequentially-operating oil hydraulic cylinder that provides a kind of using effect good is provided technical problem to be solved in the utility model.
Technical problem to be solved in the utility model adopts following technological scheme to realize:
The sequentially-operating oil hydraulic cylinder, comprise cylinder body, upper cover plate, lower cover plate, piston and piston rod, described upper cover plate and lower cover plate are separately positioned on the two ends up and down of cylinder body, all be provided with oilhole on upper cover plate and lower cover plate, described piston is positioned at the inside of cylinder body, and described piston rod is arranged on piston, it is characterized in that, described upper cover plate is provided with the control hydraulic fluid port, on described control hydraulic fluid port and piston, all is provided with one-way valve.
One-way valve in described control hydraulic fluid port is corresponding with the one-way valve on piston.
When piston movement arrives the limes superiors position, back down two one-way valves by the mechanical structure that is arranged on piston and oil hydraulic cylinder upper end cap, control hydraulic fluid port and working connection intercommunication, can complete the action request of next stage final controlling element, when piston, not when limes superiors is put, in the one-way valve group, two one-way valves are thrown off, and control hydraulic fluid port and working connection are obstructed, the control hydraulic fluid port does not have pressure oil, can not complete the action request of next stage final controlling element.
The beneficial effects of the utility model are: the utility model is simple in structure, and can reach the break-make  that controls next stage final controlling element oil circuit and realize that final controlling element is sequentially moving.
The accompanying drawing explanation:
Fig. 1 is the utility model structural representation.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, the sequentially-operating oil hydraulic cylinder, comprise cylinder body 1, upper cover plate 2, lower cover plate 3, piston 4 and piston rod 5, described upper cover plate 2 and lower cover plate 3 are separately positioned on the two ends up and down of cylinder body 1, all be provided with oilhole 6 on upper cover plate 2 and lower cover plate 3, piston 4 is positioned at the inside of cylinder body 1, and piston rod 5 is arranged on piston 4, upper cover plate 2 is provided with control hydraulic fluid port 7, on control hydraulic fluid port 7 and piston 4, all is provided with one-way valve 8.The one-way valve 8 that the control hydraulic fluid port is 7 li is corresponding with the one-way valve 8 on piston 4.
Above demonstration and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
