Abstract
The invention provides a middle cylinder of a plunger-type hydraulic cylinder. The middle cylinder comprises a steel barrel, a plunger, a connecting column, a seal ring, a piston column, a first oil inlet and a second oil inlet and a prefill valve. The plunger and the connecting column are arranged in the steel barrel, the seal ring is arranged between the steel barrel and the plunger, the first oil inlet and the second oil inlet are arranged at the top end of a vertical part of the piston column, the prefill valve is arranged on the steel barrel, a cross hole is formed on one side of the lower end of the first oil inlet, the bottom of the plunger is connected onto the connecting column through bolts, the piston column is in an inverted T shape and penetrates the center of the plunger and the steel barrel. The middle cylinder of the plunger-type hydraulic cylinder is simple in structure; the plunger can quickly fall and retract so that cost of an auxiliary cylinder is omitted, cost is reduced and efficiency is improved.
Description
Technical field
The present invention relates to cylinder in a kind of plunger type cylinder, belong to field of mechanical technique.
Background technique
Plunger type cylinder can change hydraulic pressure into mechanical energy, make the hydraulic actuator of straight line single-acting campaign.It is simple in structure, good manufacturability, reliable operation.Therefore in the hydraulic system of various machineries, be used widely; Traditional plunger type cylinder is single-acting cylinder, because speed is slow during big its effect of cylinder diameter, and can not fast lifting, need add auxiliary cylinders in both sides, increased cost.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, cylinder in a kind of plunger type cylinder is provided.
Cylinder in the plunger type cylinder of the present invention, comprise steel cylinder, be located at plunger, attachment post in the steel cylinder, be located at seal ring, the piston column between steel cylinder and the plunger, first filler opening that is located at piston column vertical component top and second filler opening and be located at liquid-filling valve on the steel cylinder, lower end one side of described first filler opening is provided with cross-drilled hole, the bottom of described plunger is connected on the attachment post by bolt, described piston column is inverted T-shape, through the center of plunger and steel cylinder.
Be connected with fuel tank on the described liquid-filling valve.
Cylinder in the plunger type cylinder of the present invention has following technique effect: simple in structure, plunger can descend and reclaim fast, has saved the cost of auxiliary cylinders, reduces cost, raises the efficiency.
Description of drawings
Fig. 1 is structural drawing of the present invention.
Wherein, 1 is steel cylinder, and 2 is plunger, and 3 is attachment post, and 4 is seal ring, and 5 is piston column, and 6 is first filler opening, and 7 is second filler opening, and 8 is liquid-filling valve, and 9 is fuel tank.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail, so that technical solution of the present invention is easier to understand, grasp.
As shown in Figure 1, cylinder in the plunger type cylinder of the present invention, comprise steel cylinder 1, be located at plunger 2, attachment post 3 in the steel cylinder 1, be located at seal ring 4, the piston column 5 between steel cylinder 1 and the plunger 2, first filler opening 6 that is located at piston column 5 vertical component tops and second filler opening 7 and be located at liquid-filling valve 8 on the steel cylinder 1, lower end one side of described first filler opening 6 is provided with cross-drilled hole, the bottom of described plunger 2 is connected on the attachment post 3 by bolt, described piston column 5 is inverted T-shape, through the center of plunger 2 with steel cylinder 1.
Be connected with fuel tank 9 on the described liquid-filling valve 8.
Working principle of the present invention is: liquid-filling valve 8 charges into hydraulic oil in cylinder, promotes plunger 2, and 7 oil-feeds of second filler opening enter plunger 2 inner chambers simultaneously, 6 oil returns of first filler opening, thus plunger 2 can be descended fast; Liquid-filling valve 8 oil returns, plunger 2 is regained by ambient pressure, and 6 oil-feeds of first filler opening enter plunger 2 inner chambers simultaneously, 7 oil returns of second filler opening, thus plunger 2 can be reclaimed fast.
Should be noted that at last that obviously those skilled in the art can carry out various changes and distortion to this patent and not break away from the spirit and scope of the present invention.Like this, if these modifications of this patent and distortion belong within the scope of this patent claim and equivalent technologies thereof, then this patent also is intended to comprise these changes and distortion.
Claims (2)
