Description
Technical field
The utility model belongs to petroleum drilling engineering well logging equipment technical field, relates in particular to a kind of hydraulic pressure core cutter.
Background technology
In oil exploitation and exploration process, often to carry out coring to the stratum, to take out core as the research sample, the vertical face of core need be cut and study, many cores come from the dark stratum of several kms, have higher hardness and irregular texture, cut very to be not easy, and the geology brainstrust needs from position and the angle wanted to cut, and is then more difficult.Traditional way is to cut out by force with a high rigidity chopper, also have indivedual use hydraulic way to cut, but its structural manufacturing process is simple, and there is following some deficiency in these incision methods:
When (1) cutting with chopper, time-consuming, effort is done the section of core very badly, does not reach expert's purpose.
(2) easy hydraulic cutter is simple in structure, often is cutter distortion, support bending, and is bad to the attitude control of core.
(3) when cutting with above two kinds of methods, the core fragment splashes everywhere, loses crucial information, also operating personnel is formed injury simultaneously.
The utility model content
Problem to be solved in the utility model just provides a kind of hydraulic pressure core cutter accurate, safe in utilization that cuts.
For addressing the above problem, the technical solution adopted in the utility model is: comprise that the top is provided with the main truss of pretension worm screw, be disposed with knife edge in the described main truss from top to bottom, have the core mounting table of the centre joint, following incision knife and jack, following incision knife can move up and down at the centre joint of core mounting table.
Its additional technical feature is: the outer wall of described main truss and last knife edge, following matching part, incision knife position are symmetrically arranged with at least one pair of return device, and the return device is provided with upper slitter stopper slot, following cutter stopper slot and return spring; The arranged outside of described main truss has the anti-transparent soft guard shield that splashes; The center of the described anti-transparent soft guard shield that splashes has the circular hole that is complementary with the pretension worm screw.
Hydraulic pressure core cutter provided by the utility model compared with prior art, have the following advantages: one, knife edge, the core mounting table that has the centre joint, following incision knife and jack on being disposed with from top to bottom in the main truss that has the pretension worm screw, following incision knife can move up and down at the centre joint of core mounting table.During cutting, core is placed on the core mounting table evenly, makes it to contact with the blade of following incision knife, dextrorotation pretension worm screw is being pressed on the blade of knife edge under the position of hope incision, start push rod then and put forth effort on down the jack at incision knife middle part, can cut core exactly; They are two years old, the outer wall of main truss and last knife edge, following matching part, incision knife position are symmetrically arranged with at least one pair of return device, the upper slitter stopper slot that is provided with on the return device, following cutter stopper slot, limit the distance of the minimum of the 65mm that has an appointment between last knife edge, the following incision knife, can ensure operator's safety.And return spring can provide kinetic energy after each incision work is finished, and will go up knife edge automatically, descend incision knife to push back original position, gets ready for work next time.Main truss can carry the pressure of ton surplus in the of 20, and last knife edge, following incision knife have the high strength stopper slot, can ensure sturdy and durable, safe and practical; Its three, the arranged outside of main truss has the anti-transparent soft guard shield that splashes, and can go up knife edge, incision knife covers fully down, puts, can raise during coring.In the moment of cutting core, little landwaste can be subjected to quick-fried power and splash, and the transparent anti-soft guard shield that splashes can block flying chip fully, makes it fly not go out and hurt sb.'s feelings, and also is more conducive to the researcher and collects.And the center of the anti-transparent soft guard shield that splashes has the circular hole that is complementary with the pretension worm screw, makes it to be placed in easily on the pretension worm screw, and both sides are then sagging naturally, and are very easy to use.

The specific embodiment
Be described in further details below in conjunction with the structure and the use principle of accompanying drawing the utility model hydraulic pressure core cutter.
As shown in Figure 1, the utility model hydraulic pressure core cutter comprises main truss 1, the top of main truss 1 is provided with pretension worm screw 2, be disposed with knife edge 3 in the main truss 1 from top to bottom, have the core mounting table 4 of the centre joint, following incision knife 5 and jack 6, following incision knife 5 can move up and down at the centre joint of core mounting table 4, the outer wall of main truss 1 and last knife edge 3, following matching part, incision knife 5 position are symmetrically arranged with at least one pair of return device 7, and the arranged outside of main truss 1 has the anti-transparent soft guard shield 8 that splashes.As shown in Figure 2, the center of the anti-transparent soft guard shield 8 that splashes has the circular hole 9 that is complementary with the pretension worm screw.As shown in Figure 3, Figure 4, return device 7 is provided with upper slitter stopper slot 10, following cutter stopper slot 11, return spring 12.
During manufacturing, earlier with jack 6, down incision knife 5, have the centre joint core mounting table 4, go up knife edge 3, pretension worm screw 2 sets gradually with main truss 1, fixedly ear 13 with return device 7 is connected by the Luo bolt with main truss 1 then, and the circular hole 9 at transparent soft guard shield 8 centers of will preventing at last splashing is aimed at the pretension worm screws and packaged and get final product.
During use, core is placed on the core mounting table 4 evenly, make it to contact with the blade of following incision knife 5, dextrorotation pretension worm screw 2 is being pressed on the blade of knife edge 3 under the position of hope incision, and jack 6 pushed up mutually with the elasticity strength of following incision knife 5 middle parts dependence return device 7 and closed this moment.Then, start jack 6, can cut core exactly.The upper slitter stopper slot 10 that is provided with on the return device 7, cutter stopper slot 11 have down limited last knife edge 3, have an appointment between the incision knife 5 distance of minimum of 65mm down, can ensure operator's safety.And return spring 12 can provide kinetic energy after each incision work is finished, and will go up knife edge 3 automatically, descend incision knife 5 to push back original position, gets ready for work next time.The anti-transparent soft guard shield 8 that splashes will be gone up knife edge 3, incision knife 5 covers fully down, can do 360 ° of whole rotations, and in the time will putting into or take out core, half-twist places guard shield on the universal crossbeam of main truss and gets final product.In the moment of cutting core, little landwaste can be subjected to quick-fried power and splash, and the transparent anti-soft guard shield that splashes can block flying chip fully, makes it fly not go out and hurt sb.'s feelings, and also is more conducive to the researcher and collects.
