Abstract
The utility model discloses a guide sleeve and a guide connector. The guide sleeve comprises a sleeve body, a sleeve hole is formed in the center of the sleeve body, an inlaid sleeve is installed in the sleeve hole, and a positioning groove is formed in the outer wall of the sleeve body. According to the guide sleeve, abrasion can be reduced effectively, service life is prolonged, and stability is good. Besides, the guide sleeve is prevented from falling off from a guide ring.
Description
Technical field
The utility model belongs to the depth drill manufacture field, is specifically related to a kind of fairlead and guiding connector.
Background technology
Existing depth drill needs location drilling, and existing fairlead is because there is following defective in its structural limitations:
1, because fairlead adopts common iron to make, and the wearing and tearing of fairlead are bigger in the course of the work, cause the service life of fairlead short.
2, existing fairlead lacks location design, less stable in the course of the work.
Summary of the invention
Based on this, the utility model is to overcome the defective of prior art, and a kind of fairlead and guiding connector are provided, and the utility model can effectively reduce wear, and has prolonged service life, and good stability.
Its technical scheme is as follows:
A kind of fairlead comprises body, is provided with trepanning at the center of body, is provided with mosaic set in trepanning, is provided with locating slot at the outer wall of body.
Below further technical scheme is described:
The external diameter of first end of described body forms the transition neck between first end and second end less than the external diameter of second end, described mosaic set is located at the center of first end of described body.
The cross section of described locating slot is half-cylindrical, and this locating slot is positioned at second end of described body.
A kind of guiding connector, comprise fairlead and guide collar, this fairlead comprises body, center at body is provided with trepanning, is provided with mosaic set in trepanning, is provided with locating slot at the outer wall of body, middle part in guide collar is provided with centre bore, be provided with the locating hole of radial direction in guide collar, after fairlead was installed in the centre bore of guide collar, keeper passed behind locating hole and the locating slot guide collar and fairlead location.
Advantage or principle to the aforementioned techniques scheme describes below:
Because this fairlead adopts two-part structure, a part is body, another part is mosaic set, body and mosaic set adopt unlike material, as: mosaic set adopts the material more wear-resisting than body, can significantly improve the wearability of fairlead, prolong its service life, after the outer wall of body is provided with locating slot, can improve the stability of fairlead, avoid fairlead to come off from guide collar.

The specific embodiment
Below embodiment of the present utility model is elaborated:
As shown in Figure 1 to Figure 3, a kind of guiding connector, comprise fairlead 10 and guide collar 20, this fairlead 10 comprises body 11, is provided with trepanning at the center of body 11, in trepanning, be provided with mosaic set 14, outer wall at body 11 is provided with locating slot 12, is provided with centre bore at the middle part of guide collar 20, is provided with the locating hole 21 of radial direction in guide collar 20, after fairlead 10 was installed in the centre bore of guide collar 20, keeper after passing locating hole 21 and locating slot 12 was located guide collar 20 and fairlead 10.
Wherein, the external diameter of first end of described body 11 forms transition neck 13 between first end and second end less than the external diameter of second end, and described mosaic set 14 is located at the center of first end of described body 11; The cross section of described locating slot 12 is half-cylindrical, and this locating slot 12 is positioned at second end of described body 11.
The described fairlead of present embodiment has following advantage:
Because this fairlead 10 adopts two-part structure, a part is body 11, another part is mosaic set 14, body 11 adopts unlike material with mosaic set 14, in the present embodiment, the body 11 of guide collar 20 and fairlead 10 all adopts the high SUG-2 material of wearability, the heat treatment stiffened arrives up to 55-60HRC again, wear-resisting wearing and tearing are little, improve required precision, and mosaic set 14 adopts the wolfram steel material, its hardness is up to 80-90HRC, substantially reach zero wearing and tearing during work, can significantly improve the wearability of fairlead 10, prolong its service life, after the outer wall of body 11 is provided with locating slot 12, can improve the stability of fairlead 10, avoid fairlead 10 to come off from guide collar 20.
The above embodiment has only expressed the specific embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
