Abstract
The invention discloses a kind of hydraulic cylinders with permeability alarm function, belong to hydraulic cylinder technical field, including cylinder body, end cap and piston rod, the cylinder cap is fixed on the cylinder body by fastener, it is characterized by: being equipped with transparent lantern ring on the outside of the cylinder body and cylinder cap seam crossing, the medial surface of the lantern ring has groove, and annular chamber is constituted between the groove and the gray iron lateral surface, oil suction is filled in the annular chamber and prompts medium.The micro hydraulic oil that hydraulic cylinder oozes out can be adsorbed and be expanded by the present invention, to be plant maintenance personnel obviously to prompt, so that plant maintenance personnel be enabled to find the appearance of oil leakage problem in time, solve oil leakage problem as early as possible.
Description
Technical field
The invention belongs to hydraulic cylinder technical field more particularly to a kind of hydraulic cylinders with permeability alarm function.
Background technique
Hydraulic cylinder is indispensable functional component on large-scale engineering machinery.Hydraulic cylinder includes gray iron and piston rod,
Cylinder cap is fixed on cylinder body lower end by fastener, and piston rod is inserted on cylinder body, the inner end fixed piston portion of piston rod, piston
The cavity of cylinder interior is separated into two pressure chambers by portion.
After hydraulic cylinder long-term work, because of reasons such as sealing element agings, the junction of cylinder body and cylinder cap will appear sealing and lose
Imitate oil leak the case where, once there is hydraulic oil leakage, not only can contaminated equipment, also will affect the normal work of equipment.Hydraulic cylinder
It is permeability initial stage, not noticeable because oil mass leakage is smaller, so the hydraulic cylinder for sealing problem occur is difficult to be tieed up at permeability initial stage
It repairs.
Summary of the invention
In view of the problems of the existing technology, the present invention provides a kind of solution existing hydraulic cylinder permeability initial stage is not noticeable
The problem of the hydraulic cylinder with permeability alarm function.
The invention is realized in this way a kind of hydraulic cylinder with permeability alarm function, including cylinder body, end cap and piston
Bar, the cylinder cap are fixed on the cylinder body by fastener, it is characterised in that: are pacified in the outside of the cylinder body and cylinder cap seam crossing
Equipped with transparent lantern ring, the medial surface of the lantern ring has groove, constitutes between the groove and the gray iron lateral surface
Annular chamber, the annular chamber is interior to prompt medium filled with oil suction.
Heretofore described hydraulic cylinder has lantern ring, what the oil suction prompt medium fixed in lantern ring can ooze out hydraulic cylinder
Micro hydraulic oil adsorbs and expands, with to plant maintenance personnel obviously to prompt, so that plant maintenance personnel be enabled to find to seep in time
The appearance of oily problem, solves oil leakage problem as early as possible.
In the above-mentioned technical solutions, it is preferred that the lantern ring is made up of by two the semi-circular ring that fastener connects.This knot
The lantern ring of structure easy to disassemble can be installed.
In the above-mentioned technical solutions, it is preferred that the oil suction prompt medium is discoloration adsorption cotton.Discoloration adsorption cotton not only may be used
With the hydraulic oil range diffusion that will be permeated, better effect can be prompted with discoloration prompt.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
In figure, 1, cylinder body；2, end cap；3, piston rod；4, lantern ring；5, groove；6, oil suction prompts medium.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
For the drawback that solution existing hydraulic cylinder permeability initial stage is not noticeable, the present invention provides one kind, and there is permeability to warn function
The hydraulic cylinder of energy, this hydraulic cylinder can provide standby signal at hydraulic cylinder permeability initial stage, plant maintenance personnel be enabled to find to ask as early as possible
Topic.Structure in order to further illustrate the present invention, it is as follows to be described with reference to the accompanying drawings book:
Please refer to Fig. 1；A kind of hydraulic cylinder with permeability alarm function, including cylinder body 1, end cap 2 and piston rod 3, it is described
Cylinder cap is fixed on the cylinder body by fastener.Cylinder body, end cap and piston rod are the basic components that the present invention states out, because of liquid
Cylinder pressure is component known to machinery field, the connection relationship between other cylinder parts or component is not done herein superfluous
It states.In the present embodiment, cylinder cap is fixed on the bottom of cylinder body by clamping screw.
Transparent lantern ring 4 is installed, in the present embodiment, lantern ring is transparent plastic on the outside of the cylinder body and cylinder cap seam crossing
Material.The medial surface of the lantern ring has groove 5, and groove is annular.Structure between the groove and the gray iron lateral surface
Circularize chamber, the seam crossing of cylinder body and cylinder cap is located in annular chamber.Medium is prompted filled with oil suction in the annular chamber.This implementation
In example, the lantern ring is made up of by two the semi-circular ring that fastener connects.The first place of two halves torus passes through clamping screw group
Part locking, to be fixed on the outside of the cylinder body of hydraulic cylinder, the lantern ring of this structure easy to disassemble can be installed.
The oil suction prompt medium is discoloration adsorption cotton.Discoloration adsorption cotton can not only expand the hydraulic oil range of infiltration
It dissipates, better effect can be prompted with discoloration prompt.
Discoloration adsorption cotton is matured product currently on the market, also has applicant to be applied for patent and openly, such as
ZL201410604144.8。
The lantern ring one side wall opposite with side of cylinder block has interior convex surface and arcuate surface, and the interior convex surface is by the oil suction
The seam crossing in the cylinder body and cylinder cap is held out against in the middle part of prompt medium.
Above structure can not only enable the seam crossing reliable contacts of oil suction prompt medium and cylinder body and cylinder cap, guarantee that oil suction mentions
Show that medium fully absorbs permeability.In addition, the transparent material of convex lens shape has amplification effect to the color change of oil suction prompt medium,
Further it is convenient for the observation of plant maintenance personnel.
In the description of the present invention, it should be noted that term " center ", "upper", "lower", "left", "right", "vertical",
The orientation or positional relationship of the instructions such as "horizontal", "inner", "outside" be based on the orientation or positional relationship shown in the drawings, merely to
Convenient for description the present invention and simplify description, rather than the device or element of indication or suggestion meaning must have a particular orientation,
It is constructed and operated in a specific orientation, therefore is not considered as limiting the invention.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
