Abstract
The utility model discloses a kind of gamma logging instrument probe earthquake resistant structure, comprise multiplier tube, one end of multiplier tube is connected with crystal, the other end and the base of crystal are bolted, and have clamped damping rubber pad between base and crystal, base are symmetrically distributed with bar shaped screw, described bolt is coated with in bar shaped screw, one end of bolt is rotated with on crystal, and the other end of bolt is exposed to outside described bar shaped screw, and base to move back and forth along with stretching of damping rubber pad on described bolt.Damping rubber pad is provided with between the utility model base and crystal, relative position change is there is between base and crystal when working stressed, when damping rubber pad is compressed or when cushioning after damping rubber pad compression, base can to move back and forth on described bolt along with stretching of damping rubber pad, efficiently solve gamma-ray tool in transit with upper well construction process in because intense impact and vibrations are to the damage of crystal and photomultiplier.
Description
Technical field
The utility model relates to gamma-ray tool, is specifically related to a kind of gamma logging instrument probe earthquake resistant structure.
Background technology
Existing gamma logging instrument probe and skeleton are Hard link, and gamma-ray probe belongs to breakables from composition, owing to not having damping device, because shock and vibration easily cause crystal and photomultiplier to damage in transport and well logging construction.
Utility model content
In order to solve the problems referred to above that prior art exists, the utility model provides a kind of gamma logging instrument probe earthquake resistant structure.
The technical scheme that the utility model adopts is: a kind of gamma logging instrument probe earthquake resistant structure, comprise multiplier tube, one end of multiplier tube is connected with crystal, the other end and the base of crystal are bolted, clamped damping rubber pad between base and crystal, base has been symmetrically distributed with bar shaped screw, described bolt penetrates in this bar shaped screw and makes one end of bolt be rotated with on crystal, the other end of bolt is exposed to outside bar shaped screw, and base to move back and forth along with stretching of damping rubber pad on described bolt.
Preferably, the other end of described crystal is provided with circular groove, one end that described base connects with crystal is also provided with circular groove, in base circular groove, described damping rubber pad is housed, the circular groove spiral-lock of base termination is outside the circular groove of crystal termination, the cell wall of base circular groove is distributed with described bar shaped screw, described bolt is spun solid on the circular groove of described crystal after penetrating this bar shaped screw.
Preferably, the length of described bar shaped screw is greater than the external diameter of described bolt, and width and the described bolt of bar shaped screw are suitable.
Preferably, the circular groove height of described base termination is equal with the height of crystal termination circular groove.
Preferably, the thickness of described damping rubber pad is greater than the height of base termination circular groove.
Preferably, described damping rubber pad is cylinder.
The beneficial effects of the utility model are: be provided with damping rubber pad between the utility model base and crystal, base and crystal affixed by bolt, screw base penetrating this bolt is bar shaped, bolt leaves certain interval after penetrating the bar shaped screw of base, relative position change is there is between base and crystal when working stressed, when damping rubber pad is compressed or when cushioning after damping rubber pad compression, base can to move back and forth on described bolt along with stretching of damping rubber pad, this earthquake resistant structure efficiently solve gamma-ray tool in transit with upper well construction process in because intense impact and vibrations are to the damage of crystal and photomultiplier.
Accompanying drawing explanation
Fig. 1. be structural representation of the present utility model.
In figure: 1, multiplier tube; 2, crystal; 3, base; 4, damping rubber pad; 5, bolt; 6, box hat sheath.
Detailed description of the invention
As shown in Figure 1, the utility model provides a kind of gamma logging instrument probe earthquake resistant structure, comprise multiplier tube 1, box hat sheath 6 is installed outside multiplier tube 1, one end of multiplier tube 1 connects with one end of crystal 2, the other end of described crystal 2 is provided with circular groove, this end of crystal 2 is connected with base 3, one end that described base 3 connects with crystal 2 is also provided with circular groove, columniform damping rubber pad 4 is equipped with at the middle part of this circular groove, the internal diameter of base 3 termination circular groove is greater than the external diameter of described crystal 2 termination circular groove, the circular groove spiral-lock of base 3 termination is outside the circular groove of crystal 2 termination, the circular groove height of described base termination is equal with the height of crystal 2 termination circular groove, the thickness of damping rubber pad 4 is greater than the height of base termination circular groove, the cell wall of base circular groove is symmetrically distributed with bar shaped screw, bolt 5 is coated with in the bar shaped screw of base 3, the length of bar shaped screw is greater than the external diameter of bolt 5, width and the bolt 5 of bar shaped screw are suitable, one end of bolt 5 is rotated with on the circular groove of crystal 2, the other end of bolt 5 is exposed to outside the bar shaped screw of base 3, and base 3 to move back and forth along with stretching of damping rubber pad 4 on bolt 5.
During operation, after gamma-ray tool is stressed, probe vibrations, damping rubber pad 4 is accompanied between base 3 and crystal 2, there is relative position when working stressed between base 3 and crystal 2 to change and make damping rubber pad 4 that elastic deformation occur, that is when damping rubber pad 4 recovers ortho states after being compressed or compressing, due to bolt 5 penetrate the bar shaped screw of base 3 after leave certain interval, base 3 can to move back and forth on bolt 5 along with stretching of damping rubber pad 4, can cushion gamma-ray tool in transit or there are intense impact and vibrations in upper well construction process time be delivered in active force on probe, and then the damage avoided crystal 2 and photomultiplier 1.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; every have identical with the application or akin technical scheme, all drops within protection domain of the present utility model.
