Abstract
The utility model relates to a super-large-diameter hydraulic cylinder which comprises a cylinder bottom and a cylinder head, a cylinder-bottom-face one-way valve is provided on the end-face of the cylinder bottom, the cylinder-bottom-face one-way valve is channeled to the eyelet on the cylinder bottom, the cylinder-head-face one-way valve is provided on the head-face of the cylinder head, and the cylinder-head-face one-way valve is channeled to the eyelet on the cylinder head. With the one-way valves provided on the head-face and the end-face, the utility model meets the specifications of buffering and low pressure startup, and it is capable of avoiding the breakages on the cylinder head and the cylinder bottom caused by impacts.
Description
[technical field]
The utility model relates to and a kind ofly can satisfy under the prerequisite that buffering requires, realize low voltage starting super large cylinder diameter oil hydraulic cylinder.
[background technique]
Automation is one of modern mechanical developing direction.Hydraulics is to realize the technical foundation of automation.Oil hydraulic cylinder is as the executive component of hydraulic system, and its successful operation is the essential condition that realizes mechanical automation.
At present, be quite to improve to reach successfully for the designing technique of the oil hydraulic cylinder of cylinder diameter≤320mm, but for the super large cylinder diameter, also need constantly to go perfect as the designing technique of the oil hydraulic cylinder of cylinder diameter 〉=500mm.
Two kinds of structures of the general employing of the design of super large oil hydraulic cylinder at present, the first does not have buffer structure, shortcoming is: when the piston rod motion speed is exceedingly fast, because volume is big, quality is heavy, mass inertia is big, the kinetic energy that produces under equal velocity conditions is very big, breaks cylinder head cylinder bottom end face in the course of the work easily; It two is to have adopted buffer structure and at the outer surface of oil hydraulic cylinder one-way valve and throttle valve have been installed, shortcoming is: when space outerpace has in limited time, be difficult to realize artificial adjustment in good time after oil hydraulic cylinder installs, cause cushioning effect poor easily, the drawback that breakout pressure is big, thus the normal use of oil hydraulic cylinder influenced.
[model utility content]
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of can satisfy the buffering requirement, avoids the cylinder head cylinder bottom to be attacked the super large cylinder diameter oil hydraulic cylinder of damage, realized the super large cylinder diameter oil hydraulic cylinder of low voltage starting again.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of super large cylinder diameter oil hydraulic cylinder, comprise cylinder bottom and cylinder head, be provided with cylinder bottom end face one-way valve at described cylinder bottom end face, this cylinder bottom end face one-way valve communicates with the cylinder bottom hydraulic fluid port, be provided with cylinder head end face one-way valve at described cylinder head end face, this cylinder head end face one-way valve communicates with the cylinder head hydraulic fluid port.
The beneficial effects of the utility model are: by being respectively equipped with one-way valve at cylinder bottom end face and cylinder head end face, can satisfy the buffering requirement, can avoid the cylinder head cylinder bottom to suffer to attack and damage, can realize low voltage starting again.
[description of drawings]
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-cylinder bottom, 2-cylinder bottom hydraulic fluid port, 3-cylinder bottom end face one-way valve, 4-piston, 5-cylinder head end face one-way valve, 6-cylinder head, 7-cylinder head hydraulic fluid port.
[embodiment]
Referring to Fig. 1, a kind of super large cylinder diameter oil hydraulic cylinder, comprise cylinder bottom 1 and cylinder head 6, be provided with cylinder bottom end face one-way valve 3 at described cylinder bottom 1 end face, this cylinder bottom end face one-way valve 3 communicates with cylinder bottom hydraulic fluid port 2, be provided with cylinder head end face one-way valve 5 at described cylinder head 6 end faces, this cylinder head end face one-way valve 5 communicates with cylinder head hydraulic fluid port 7.
When cylinder head hydraulic fluid port 7 entered pressure oil and piston 4 and is in cylinder head 6 positions, cylinder head end face one-way valve 5 played straight-through effect, and pressure oil affacts on the piston 4 by this path rapid large-area ground, and oil cylinder is pushed to cylinder bottom 1, thereby realizes startup fast; In this working procedure, cylinder bottom end face one-way valve 3 plays a part to open circuit always; When cylinder bottom 1 entered buffer stage, cylinder bottom end face one-way valve 3 did not influence this work; When cylinder bottom hydraulic fluid port 2 entered pressure oil and piston 4 and is in cylinder bottom 1 position, cylinder bottom end face one-way valve 3 played straight-through effect, and pressure oil affacts on the piston 4 by this path rapid large-area ground, and oil cylinder is pushed to cylinder head 1, thereby realizes startup fast; In this working procedure, cylinder head end face one-way valve 3 plays a part to open circuit always; When cylinder head 6 entered buffer stage, cylinder head end face one-way valve 5 did not influence this work.The utility model has satisfied the buffering requirement, avoids the cylinder head cylinder bottom to suffer to attack and damages, and has realized the designing requirement of low voltage starting again.
