Description
Technical field
The present invention relates to oil-well drilling equipment, particularly a kind of oil drilling retracting cylinder.
Background technology
Oil is a kind of thickness, dark brown liquid.There is petroleum storage upper crustal some areas.Main component is the mixture of various alkane, cycloalkane, aromatic hydrocarbon.The one-tenth oil machine reason of oil has biogenic deposit to become oil and petrochemical industry oil two kinds of theories, and the former more widely accepts, think oil be ancient times ocean or lake in biology formed through very long evolution, belong to biogenic deposit and become oily, non-renewable; The latter thinks that oil is generated by the carbon of itself in the earth's crust, has nothing to do with biology, renewable.Oil is mainly used as fuel oil and gasoline, is also many chemical industries, as the raw material of solution, chemical fertilizer, pesticide and plastics etc.
And along with the progress of science and technology, there is the lifting of expansion type in the use amount of oil, and be not applied on a large scale in productive life at new forms of energy, oil is still an important energy, therefore country only augments the demand of oil and subtracts, and in oil exploitation, needs to use various equipment, and these equipment are made up of various component, retracting cylinder is then one of them very important component.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, the oil drilling retracting cylinder of simple, the easy to assembly and long service life of a kind of structure is provided.
Object of the present invention is achieved through the following technical solutions: a kind of oil drilling retracting cylinder, it comprises retracting cylinder body, multi-stage stairs hole is offered in described retracting cylinder body, the left end of described retracting cylinder body offers first step, the right-hand member of retracting cylinder body offers second step, an annular protrusion is also provided with between first step and second step, described annular protrusion offers a telescopic chute, and the end of telescopic chute extends to the left side of first step, a groove opening is offered in the left part of telescopic chute, telescopic chute also offers an open slot, described groove opening is communicated with open slot, the left part of described first step circumferentially also offers multiple bore hole, a cannelure is offered in described bore hole, the end of described second step circumferentially also offers multiple fraising.
Described stepped hole is three grades, and is followed successively by first order stepped hole, second level stepped hole, third level stepped hole from left to right, and second level stepped hole is less than the diameter of first order stepped hole, and the 3rd stepped hole is than the diameter of second level stepped hole.
Described fraising is three and is evenly distributed on same periphery.
Described bore hole is three and is evenly distributed on same periphery.
Described telescopic chute and the link of open slot have a fillet.
The end of described first step also offers a deep-slotted chip breaker, and deep-slotted chip breaker is positioned at the side of groove opening
The present invention has the following advantages: retracting cylinder of the present invention, and its structure is simple, is easy to processing, and fraising and bore hole be uniformly distributed, the connectivity robustness of retracting cylinder can be ensured, retracting cylinder operationally uniform force can be made again, thus extend the application life of retracting cylinder.
Accompanying drawing explanation

Fig. 2 is the cross-sectional schematic of Fig. 1;
In figure, 1-retracting cylinder body, 2-first step, 3-second step, 4-annular protrusion, 5-telescopic chute, 6-groove opening, 7-open slot, 8-bore hole, 9-cannelure, 10-reams, 11-first step hole, 12-second step hole, 13-the 3rd stepped hole, 14-fillet, 15-deep-slotted chip breaker.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described, and protection scope of the present invention is not limited to the following stated:
As depicted in figs. 1 and 2, a kind of oil drilling retracting cylinder, it comprises retracting cylinder body 1, multi-stage stairs hole is offered in described retracting cylinder body 1, the left end of described retracting cylinder body 1 offers first step 2, the right-hand member of retracting cylinder body 1 offers second step 3, an annular protrusion 4 is also provided with between first step 2 and second step 3, described annular protrusion 4 offers a telescopic chute 5, and the end of telescopic chute 5 extends to the left side of first step 2, a groove opening 6 is offered in the left part of telescopic chute 5, telescopic chute 5 also offers an open slot 7, described groove opening 6 is communicated with open slot 7, the left part of described first step 2 circumferentially also offers multiple bore hole 8, a cannelure 9 is offered in described bore hole 8, the end of described second step circumferentially also offers multiple fraising 10, the end of described first step 2 also offers a deep-slotted chip breaker 15, deep-slotted chip breaker is positioned at the side of groove opening 6.
In this enforcement, described stepped hole is three grades, and be followed successively by first order stepped hole 11, second level stepped hole 12, third level stepped hole 13 from left to right, and second level stepped hole 12 is less than the diameter of first order stepped hole 11,3rd stepped hole 13 is than the diameter of second level stepped hole, when retracting cylinder coordinates with cylinder chip, cylinder core penetrates from first step hole 11, and then passes from the 3rd stepped hole.
In the present embodiment, described fraising 10 is three and is evenly distributed on same periphery, further, described bore hole 8 is three and is evenly distributed on same periphery, so both to ream easily 10 and the processing of bore hole 8, and after retracting cylinder body 1 is fixing, also can accepts evenly, ensure its application life.
