Further, the inwall of described cylindrical shell bottom is distributed with 3 circle wire rope.
Further, removably mounting pipe is connected with between described installing port and drilling rod.
Further, described installing port and described drilling rod are screwed onto the two ends of described mounting pipe respectively.
The boring fishing socket structure that the utility model provides is simple, easy to operate, and effectively can salvage the block junk in boring and slender rod piece class junk, effectively improves the salvaging efficiency of boring junk.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of preferred boring fishing socket of the utility model;
Fig. 2 is the top view of the boring fishing socket shown in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, a preferred embodiment of the present utility model is described in detail.The identical Reference numeral of wherein identical component represents.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometric center respectively.
As depicted in figs. 1 and 2, the boring fishing socket that the utility model provides comprises circular cylindrical shell 1, and the top of described cylindrical shell 1 is provided with the installing port for being connected with drilling rod, and described cylindrical shell 1 preferably adopts pipe thickness to be the seamless light pipe of 10mm.Certainly, the utility model can also select the material of other thickness according to cylindrical shell 1 internal diameter, repeat no more herein.
As depicted in figs. 1 and 2, the inwall of the bottom of cylindrical shell 1 of the present utility model is provided with many wire rope 2 equably, described wire rope 2 is preferably the wire rope that diameter is 16mm, the root of described wire rope 2 is fixed on the inwall of described cylindrical shell 1, the end of described wire rope 2 is inclined upwardly, and extend towards the axis direction of described cylindrical shell 1, the root of described many wire rope 2 is on the circular inwall being distributed in described cylindrical shell 1, thus the end of many wire rope 2 is intersected mutually at the axle center place of described cylindrical shell 1, form net structure.
In order to effectively can fix the junk in boring, the junk in holing is avoided to come off from the space of steel cord ends, the length of wire rope 2 of the present utility model should be greater than the radius of described cylindrical shell 1, thus makes the junk in described boring clamp and be fixed on the end of many wire rope 2.Certainly, in order to save material, reduce costs, the length of wire rope of the present utility model is preferably less than the internal diameter of described cylindrical shell 1.
During use, first, the boring fishing socket of cylindrical shell 1 size coupling is selected according to the internal diameter of boring, then boring fishing socket is fixed on the end of described drilling rod, then the junk in boring is aimed at, described boring fishing socket is stretched into boring, under external force, junk in boring, such as slender rod piece can be fastened in the net structure that described wire rope 2 formed, the wire rope arranged that is inclined upwardly not only contributes to junk and snaps in net structure, junk landing from net structure under the Action of Gravity Field of self can also be avoided, finally, fishing junk in boring fishing socket can be gone out boring by lift drilling rod.
As shown in Figure 1, wire rope 2 of the present utility model is preferably to surface thereof 15 °-25 °, and namely described wire rope and horizontal plane form the angle of 15 °-25 °.Those skilled in the art should understand that and be, if the angle of inclination of described wire rope 2 is excessive, be unfavorable for forming net structure, junk easily thus slide in space between wire rope 2 end, therefore be not easy to block junk, otherwise, if the angle of inclination of described wire rope 2 is too small, although the end of described wire rope 2 is easy to form net structure, but junk is difficult to enter described net structure, and cancellated support force obviously reduces, junk is easy equally under the Action of Gravity Field of self, thus landing in net structure.Prove through lot of experiments, the acclivitous angle of described wire rope 2 is more preferably 20 °.
In order to improve further described wire rope 2 form cancellated supporting capacity, the utility model preferably distributes the described wire rope 2 of 3 circle on the inwall of described cylindrical shell 1 bottom, in the vertical direction distribution compound steel silk rope 2 can significantly improve net structure carrying can and holding capability to junk.Certainly, arrange a kind of preferred version that compound steel silk rope is only the present embodiment, this practicality can also arrange more multi-layered wire rope according to the weight of junk in described cylindrical shell 1, and certainly, cost of production and processing technology also can increase along with the increase of wire rope quantity.
As a kind of preferred version of the present utility model, described wire rope 2 is welded to connect on the inwall of described cylindrical shell 1.It will be understood by those skilled in the art that being welded to connect is only a kind of preferred version of the present utility model, the utility model can also adopt known in those skilled in the art other to be fixedly connected with mode, repeats no more herein
On the basis of above-described embodiment, as shown in Figure 1, the utility model is also preferably removably connected with mounting pipe 3 between described installing port and drilling rod, the internal diameter of described mounting pipe 3 is preferably less than the internal diameter of described cylindrical shell 1, one end that described cylindrical shell 1 is connected with described mounting pipe 3 is preferably shunk gradually, as shown in Figure 1, preferably in bottle shape when described mounting pipe 3 is removably mounted on described cylindrical shell 1.Operating personnel, when carrying out fishing operation to the boring of different pore size, are convenient to change the cylindrical shell 1 of different inner diameters, can be carried out compliance salvaging for concrete boring, and then improve and salvage efficiency and namely salvage effect.
More preferably, described installing port and described drilling rod are screwed onto the two ends of described mounting pipe 3 respectively, one end of described mounting pipe arranges internal thread, and the end of described drilling rod correspondingly arranges external screw thread, thus described mounting pipe 3 is removably connected to the end of described drilling rod; The other end of described mounting pipe preferably can offer external screw thread, and described cylindrical shell 1 correspondingly offers internal thread, and during use, described cylindrical shell 1 is directly fastened on the end of described mounting pipe by internal thread and externally threaded being spirally connected.It will be understood by those skilled in the art that is spirally connected is only a kind of preferred version removably connected, and the utility model can also adopt known in those skilled in the art, is applicable to the alternate manner removably connected to steel pipe, repeats no more herein.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of the utility model.
