Abstract
The utility model discloses a withdrawal tool for a magnetic axis and a magnetic body of a pulser. The withdrawal tool for the magnetic axis and the magnetic body of the pulser comprises two fixtures, a sleeve and at least two force-transmitting screws, wherein the two fixtures are formed by the fact that one cylindrical sleeve with openings at two ends, along the axial direction, is averagely divided, the two fixtures are used for clamping the magnetic axis and the magnetic body of the pulser, and one protrusion, corresponding to a groove in the outer circumferential surface of the magnetic body, is arranged on the inner wall of the lower end of each fixture. The sleeve, used for sleeving the two fixtures, is a cylindrical sleeve with an end cover arranged at one end, and clamping components are arranged on the end cover of the sleeve. The at least two force-transmitting screws are arranged on the two fixtures, and one ends, away from the magnetic body, of the at least two force-transmitting screws, are arranged in the grooves in the inner wall of the sleeve in a clamping mode. The withdrawal tool for the magnetic axis and the magnetic body of the pulser has the advantage that a torque wrench can be used to disassemble and assemble the magnetic axis and the magnetic body, so that the magnetic axis and the magnetic body can be installed in a torque mode according to the rules. In addition, the withdrawal tool for the magnetic axis and the magnetic body of the pulser can not only guarantee that the breakdown of loosening in working of the magnetic axis and the magnetic body cannot occur, but also guarantee that a connecting screw thread cannot be damaged.
Description
Technical field
The utility model relates to a kind of extracting tool, particularly, relates to a kind of pulser magnetic axis magnet extracting tool.
Background technology
In the petroleum exploration and development process, pulser is with the core instrument in brill and the positioning operation.Magnetic axis is the power source parts in the pulser, and it accepts slurry power and High Rotation Speed, for pump and the generator of pulser inside provides power.At present, owing to do not have special instrument, as shown in Figure 1, when dismounting magnetic axis magnet, not that according to the rules moment of torsion tightens, but use monkey wrench to block the groove of magnet periphery, tighten or unscrew, like this, the dynamics that tightens is little, the danger that the magnetic axis magnet releases can occur; The great efforts that tighten can produce certain harm to connecting thread.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of pulser magnetic axis magnet extracting tool, with solve now can only be with sensation moment of torsion operation shortcoming that the magnetic axis magnet is installed according to the rules, concrete technical scheme is:
A kind of pulser magnetic axis magnet extracting tool is characterized in that, comprising:
Two anchor clamps, described two anchor clamps are on average cut vertically by the cylindrical sleeves of a both ends open and are formed, and are used for clamping described pulser magnetic axis magnet, all have on the inwall of each anchor clamps lower end one with the magnet outer circumference surface on the corresponding projection of groove;
Sleeve is used for entangling described two anchor clamps, and described sleeve is the cylindrical sleeves that an end is provided with end cap, is provided with hold assembly on the end cap of described sleeve;
At least two power screws are arranged on described two anchor clamps, and are stuck in the groove that is arranged on the sleeve lining away from an end of magnet.
Preferably, the upper end of described two anchor clamps all arranges half the circumference of the sleeve where it joins the shoulder.
Preferably, described hold assembly is multiple edge body.
Preferably, described power screw is two, is arranged at respectively on described two anchor clamps.
Preferably, be provided with through hole in the middle of the end cap of described hold assembly and described sleeve.
The utility model can use torque wrench dismounting magnetic axis magnet, and moment of torsion is installed according to the rules, both can guarantee the fault that can not release in the work of magnetic axis magnet can guarantee that again thread is not damaged.

Fig. 1 is the structure chart of pulser magnetic axis magnet;
Fig. 2 is the vertical section structure chart of pulser magnetic axis magnet extracting tool among the utility model embodiment;
Fig. 3 is the vertical section structure chart when pulser magnetic axis magnet extracting tool uses among the utility model embodiment.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, hereinafter in connection with accompanying drawing embodiment of the present utility model is elaborated.Need to prove that in the situation of not conflicting, the feature among present embodiment and the embodiment is any combination mutually.
As shown in Figures 2 and 3, present embodiment discloses a kind of pulser magnetic axis magnet extracting tool, comprises two anchor clamps 2, sleeve 1 and at least two power screws 3,
Two anchor clamps 2 are on average cut vertically by the cylindrical sleeves of a both ends open and are formed, and are used for clamping pulser magnet 6, and a projection 10 corresponding with the groove 5 on the magnet outer circumference surface is all arranged on the inwall of each anchor clamps 2 lower end;
The upper end of two anchor clamps 2 all arranges half the circumference of the sleeve where it joins the shoulder, when anchor clamps 2 are stuck on the magnet 6, the half the circumference of the sleeve where it joins the shoulder of anchor clamps 2 is stuck on the upper surface of magnet 6, and anchor clamps 2 are played the location.
Preferably, be provided with through hole 9 in the middle of the end cap of hold assembly 8 and sleeve 1, be used for alleviating the weight of sleeve, save manufacturing cost.
Installation process of the present utility model is:
Although the disclosed embodiment of the utility model as above, the embodiment that described content just adopts for the ease of understanding the utility model is not to limit the utility model.Technical staff under any the utility model in the technical field; under the prerequisite that does not break away from the disclosed spirit and scope of the utility model; can do any modification and variation in the details that reaches of implementing in form; but scope of patent protection of the present utility model still must be as the criterion with the scope that appending claims was defined.
Claims (5)
