Abstract
The utility model discloses a sheet type centering device with a controllable size of an external diameter. The sheet type centering device comprises an upper main body and a lower main body movably connected with the upper main body. An upper spring and a lower spring are respectively arranged on the lateral faces of the upper main body and the lower main body; an upper sliding ring is arranged between the both ends of the upper spring, and a lower sliding ring is arranged between the both ends of the lower ring; and a centering ring is connected between the upper sliding ring and the lower sliding ring. The sheet type centering device provided by the utility model is simpler in structure and is in a split type structure that the upper main body and the lower main body are movably connected. A centering sheet is deformed by separation or approach of the upper main body and the lower main body, so that the size of the external diameter of the sheet type centering device provided by the utility model can be adjusted. The abrasion of the centering sheet is avoided, and the service life is longer. Meanwhile, the underground working effect is ensured. Furthermore, the movement stability of the upper main body and the lower main body is ensured by using a combined structure of a motor and a transmission shaft to connect, so that the use reliability of the sheet type centering device provided by the utility model is improved. The sheet type centering device provided by the utility model is good for popularization in a large range due to above advantages.
Description
Technical field
The utility model belongs to oil field downhole instrument technical field, particularly a kind of controlled outside dimension chip centralizer.
Background technology
At present, tester is carried out when going into the well work in the oil field, adopts centralizer more.The chip centralizer is comparatively use always a kind of, and its function of setting upright is realized by body resistance-strengthening tablets.The outside dimension of traditional chip centralizer is unadjustable.If the external diameter of chip centralizer is less, it is bad then to set upright effect; If the external diameter of chip centralizer is bigger, then in the process of going into the well, the body resistance-strengthening tablets easy abrasion, thus cause the chip centralizer to be unfavorable for using.These drawbacks limit the popularization on a large scale of chip centralizer.
Summary of the invention
The technical problem that the utility model will solve is: provide a kind of simple in structure, and the outside dimension scalable, result of use is better, the life-span is longer, is beneficial to the controlled outside dimension chip centralizer of popularization, to overcome the deficiency of prior art.
The utility model is to constitute like this: a kind of controlled outside dimension chip centralizer of the utility model; Comprise main body and the following main body that is connected with last subject activity; Side in last main body and following main body is respectively equipped with upper spring and lower spring; Between upper spring and lower spring two ends, be respectively equipped with slip ring and downslide rotating ring, between last slip ring and downslide rotating ring, be connected with body resistance-strengthening tablets.
In the above-mentioned controlled outside dimension chip centralizer, the described main body that goes up is to be in transmission connection with power transmission shaft that is connected with motor and following main body screw thread through motor provided thereon.
In the aforesaid controlled outside dimension chip centralizer, be provided with sealing ring 10 at the joint that descends main body 2 outsides with last main body 1.
Owing to adopted technique scheme, compare with prior art, the utility model structure is comparatively simple.The split-type structural that it adopts upper and lower subject activity to connect, through upper and lower body portion from or near making body resistance-strengthening tablets deformation, make the utility model outside dimension scalable.Avoided the wearing and tearing of body resistance-strengthening tablets, application life is longer; Simultaneously, guaranteed work in the down-hole.In addition, the utility model adopts the combining structure of motor and power transmission shaft to be connected, and has guaranteed the stationarity of upper and lower main body motion, has improved the reliability that the utility model uses.Owing to possess above-mentioned advantage, the utility model helps promoting the use of on a large scale.
Description of drawings
Fig. 1 is the structural representation of the utility model;
The last main body of being labeled as of accompanying drawing: 1-, main body under the 2-, 3-upper spring, 4-lower spring, the last slip ring of 5-, 6-downslide rotating ring, 7-body resistance-strengthening tablets, 8-motor, 9-power transmission shaft, 10-sealing ring.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
The embodiment of the utility model: the utility model is on the basis of existing chip centralizer, to improve to form; The utility model is to make up according to the preparation method of following a kind of controlled outside dimension chip centralizer; This method is the single agent structure of existing chip centralizer to be changed a social system make split type structure; The body making that is about to the chip centralizer is made up of last main body and following main body; And the two ends of its body resistance-strengthening tablets are connected on main body and the following main body separating or, can make the controlled or adjusting of outside dimension of chip centralizer like this through last main body and following main body near making body resistance-strengthening tablets deformation.
Make up according to the method described above the structural representation of a kind of controlled outside dimension chip centralizer of the utility model as shown in Figure 1; This controlled outside dimension chip centralizer comprises the structure that has the commercially available chip centralizer that is provided with the single main body structure now; The main body that it is single is changed system into the split-type structural of being made up of last main body 1 and following main body 2; Main body 2 under flexibly connecting on the last main body 1; Make it to separate or near motion, a upper spring 3 and lower spring 4 are installed respectively, install slip ring 5 and downslide rotating ring 6 respectively in the bottom of upper spring 3 and the upper end of lower spring 4 in the side of last main body 1 and following main body 2; To go up slip ring 5 and be socketed in respectively on main body 1 and the following main body 2, body resistance-strengthening tablets 7 will be installed between last slip ring 5 and downslide rotating ring 6 with downslide rotating ring 6; In order to guarantee the stationarity of main body 1 and following main body 2 relative motions, improve the reliability that the utility model uses, can motor 8 be installed on last main body 1, on motor 8, connect power transmission shaft 9, will descend main body 2 to be connected again with power transmission shaft 9; In order to protect the utility model, improve application life, can with the joint of last main body 1 sealing ring 10 be installed in following main body 2 outsides.
The embodiment of the utility model is not limited to the foregoing description, and the various variations of under the prerequisite that does not break away from the utility model aim, making all belong to the protection domain of the utility model.
