Abstract
The utility model provides a cylinder in a plunger-type hydraulic cylinder. The cylinder comprises a steel cylinder body, a plunger, a connecting pillar, a sealing ring, a piston pillar, a first oil inlet, a second oil inlet and a liquid filling valve, wherein the plunger is arranged inside the steel cylinder body, the sealing ring is arranged between the steel cylinder body and the plunger, the first oil inlet and the second oil inlet are formed in the top end of the vertical portion of the piston pillar, and the liquid filling valve is arranged on the steel cylinder body. A transverse hole is formed in one side of the lower end of the first oil inlet. The bottom of the plunger is connected to the connecting pillar through a bolt. The piston pillar is in an inverted-T shape and penetrates through the center of the plunger and the center of the steel cylinder body. The cylinder in the plunger-type hydraulic cylinder has the advantages that the structure is simple, the plunger can rapidly descend and ascend, the cost of auxiliary cylinders is eliminated, the cost is reduced, and the efficiency is improved.
Description
Technical field
The utility model relates to cylinder in a kind of plunger type cylinder, belongs to field of mechanical technique.
Background technique
Plunger type cylinder changes hydraulic energy mechanical energy into, makes 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 large its effect of cylinder diameter, and can not fast lifting, need to 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 utility model, 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, the first filler opening that is located at piston column vertical component top and the second filler opening and be located at liquid-filling valve on the steel cylinder, lower end one side of described the first filler opening is provided with cross-drilled hole, the bottom of described plunger is bolted on attachment post, 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 utility model has following technique effect: simple in structure, plunger can fast-descending and recovery, has saved the cost of auxiliary cylinders, and Cost reduction is raised the efficiency.
Description of drawings
Fig. 1 is structural drawing of the present utility model.
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 the first filler opening, and 7 is the second filler opening, and 8 is liquid-filling valve, and 9 is fuel tank.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail, so that technical solutions of the utility model are easier to understand, grasp.
As shown in Figure 1, cylinder in the plunger type cylinder of the present utility model, 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, the first filler opening 6 that is located at piston column 5 vertical component tops and the second filler opening 7 and be located at liquid-filling valve 8 on the steel cylinder 1, lower end one side of described the first filler opening 6 is provided with cross-drilled hole, the bottom of described plunger 2 is bolted on attachment post 3, 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 utility model is: liquid-filling valve 8 is filled with hydraulic oil in cylinder, promotes plunger 2, and 7 oil-feeds of the second filler opening enter plunger 2 inner chambers simultaneously, 6 oil returns of the first filler opening, thus make plunger 2 energy fast-descendings; Liquid-filling valve 8 oil returns, plunger 2 is regained by ambient pressure, and 6 oil-feeds of the first filler opening enter plunger 2 inner chambers simultaneously, 7 oil returns of the second filler opening, thus plunger 2 can be reclaimed fast.
Should be noted that at last obviously, those skilled in the art can carry out various changes and distortion to this patent and not break away from spirit and scope of the present utility model.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)
