Detailed description of the invention
The disassembling shell device of a kind of oil well logging instrument, including hydraulic-driven part, grasp device part and cylinder pad 3.
With reference to Fig. 1 and Fig. 6, hydraulic-driven part (its principle is similar to jack) is a cylindrical structure, and hydraulic cylinder 1 upper plunger (power intake) connects has boosting-rod 8, boosting-rod 8 to coordinate with force application handle 19 grafting, in order to apply bigger strength.Hydraulic cylinder 1 bottom plunger (clutch end) connects the power push-rod 7 lengthened, and hydraulic coupling is acted in cylinder pad 3 by this power push-rod；The cylinder part of hydraulic cylinder 1 downwardly extends by external thread sleeve 6, and is enclosed within outside power push-rod 7.Hydraulic chamber bottom is provided with a directional control valve 5.
With reference to Fig. 2-4, described grasp device top is a threaded connecting sleeve 9, and periphery is provided with U-lag mouth 12, and the corresponding corresponding position, two sides of U-lag mouth has the opening 13 that bolt 11 can be made to pass through；Grasping arms 10 upper end has the circular open 14 that bolt 11 can be made to pass through, and U-lag mouth 12 is inserted in the upper end of grasping arms, by bolt 11 and grasping arms upper hinge；Lock sleeve 4 is the cylinder ring body structurc of hollow, cylinder inner wall of ring body has square groove 15, it is radially provided with the screwed hole 16 for making clamping screw 17 pass through at groove, the lower end of grasping arms 10 is placed in the groove 15 of lock sleeve 4, bolt 17 is acted in grasping arms 10 by the screwed hole 16 above groove 15 so that it is hold to oil well logging instrument shell.
With reference to Fig. 5, cylinder pad is 3 in two-way U-shaped structure, on not U-shaped mouth coordinate with power push-rod 7 grafting, set screw thread 18 in the U-shaped mouth of bottom, threaded with the union joint of split logger coordinate.
In conjunction with Fig. 1, hydraulic-driven part and grasp device part are by threaded sleeve 6 and threaded connecting sleeve 9 is threaded coordinates；Described cylinder pad 3 constitutes grafting with grasping arms 10 lower end and coordinates.
Its operation principle is, first cylinder pad 3 is connected with the nipple on the oil well logging instrument being disassembled；Grasping arms 10 is connected with lock sleeve 4, i.e. grasping arms 10 lower end is correctly positioned in the groove 15 of lock sleeve, with bolt 17, grasping arms 10 is withstood on the case surface of oil well logging instrument；Thread bush 6 is connected with threaded connecting sleeve 9, and makes afterburning push rod 7 bottom combine closely with cylinder pad 3U shape groove；Directional control valve 5 on hydraulic cylinder 1 is arranged on pressing position.Moving back and forth finally by operation boosting-rod 19, be that logger shell produces mobile with main body, by adjusting the relative position of thread bush 6 and threaded connecting sleeve 9 during this, until the shell of oil well logging instrument is kept completely separate with main body, dismounting completes.
