Description
Technical field
The utility model relates to a kind of oil field equipment maintenance tool, particularly a kind of instrument of disassembling screw drill.
Background technology
Screw drill is a down-hole driven tool commonly used in the workover treatment, is mainly used in drifting, sleeve pipe and administers, sweeps the work that cement plug etc. needs well dynamic.The structure of screw drill and operation principle are comparatively complicated, and the stator of motor and rotor quality of fit require high, and the difficulty of processing and manufacturing is big, cost an arm and a leg, and in use, bit freezing, stifled fault of boring take place easily.The fault of screw drill mainly goes out on motor, if the improper meeting of processing method is peeled off motor elastomer stator and outer steel sleeve, causes drilling tool to be scrapped.
Summary of the invention
The purpose of this utility model provides a kind of screw drill and disassembles device, this screw drill is disassembled huge pulling force that the device worm drive produce and will be met the rotor of card and pull out from elastomer stator, finish disassembling to motor, in the process of disassembling, the elastomer stator of motor and the situation that outer steel sleeve is peeled off can not take place, and can not cause drilling tool to be scrapped.
The utility model is by the stator adpting flange, open sleeve, screw rod, packing ring, thrust bearing and nut are formed, the rectangular thread end of stator adpting flange is screwed onto in the elastomer stator, the rotor connector of screw rod is screwed in the tube connector of rotor, the side-wall shaft of open sleeve is to offering the opening chute, the two ends of open sleeve have left end ring flange and right-hand member ring flange respectively, the right side that is positioned at the rotor connector on the screw rod has the reaction torque slide block, has rectangular thread on the screw rod on reaction torque slide block right side, open sleeve is set in outside the screw rod, the reaction torque slide block of screw rod is arranged in the opening chute, the left end ring flange of open sleeve and stator adpting flange are with bolting together, the right-hand member head of screw rod exposes from the right-hand member of open sleeve, gasket sleeve be located at screw rod outer and with the right-hand member ring flange of open sleeve with bolting together, sheathed thrust bearing on the screw rod outside the packing ring, spiral shell is established nut on the screw rod outside the thrust bearing.
The course of work of the present utility model and principle are:
Earlier the stator adpting flange is screwed onto in the elastomer stator with the rectangular thread end, rotor connector with screw rod is screwed in the tube connector of rotor again, put open sleeve at screw rod again, when sheathed, the reaction torque slide block is slipped in the opening chute of open sleeve, then, with the left end ring flange of open sleeve and stator adpting flange together with bolting, again with after gasket sleeve is on screw rod and the right-hand member ring flange of open sleeve with bolting together, again thrust bearing is enclosed within on the screw rod; At last nut is arranged on the screw rod, uses instrument rotation nuts such as spanner, screw rod is pulled out, and then rotor is pulled out from elastomer stator.
The reaction torque slide block slides in the opening chute of open sleeve, prevents that screw rod from rotating, and then prevent that rotor from rotating in the process of pulling out.
The setting of thrust bearing is for reduction frictional force when rotating nut, and then laborsaving.
The beneficial effects of the utility model are: can be apace the rotor of motor be pulled out from elastomer stator, in the process of disassembling, the elastomer stator of motor and the situation that outer steel sleeve is peeled off can not take place, can not cause drilling tool to be scrapped.
Description of drawings,
Fig. 1 is the cross-sectional schematic of the utility model embodiment.
The specific embodiment
See also shown in Figure 1, present embodiment is by stator adpting flange 1, open sleeve 2, screw rod 3, packing ring 4, thrust bearing 5 and nut 6 are formed, the rectangular thread end 11 of stator adpting flange 1 is screwed onto among the elastomer stator A, the rotor connector 31 of screw rod 3 is screwed in the tube connector of rotor B, the side-wall shaft of open sleeve 2 is to offering opening chute 21, the two ends of open sleeve 2 have left end ring flange 22 and right-hand member ring flange 23 respectively, the right side that is positioned at rotor connector 31 on the screw rod 3 has reaction torque slide block 32, has rectangular thread 33 on the screw rod 3 on reaction torque slide block 32 right sides, open sleeve 2 is set in outside the screw rod 3, the reaction torque slide block 32 of screw rod 3 is arranged in opening chute 21, the left end ring flange 22 of open sleeve 2 and stator adpting flange 1 are with bolting together, the right-hand member head of screw rod 3 exposes from the right-hand member of open sleeve 2, packing ring 4 be set in screw rod 3 outer and with the right-hand member ring flange 23 of open sleeve 2 with bolting together, sheathed thrust bearing 5 on the screw rod 3 outside the packing ring 4, spiral shell is established nut 6 on the screw rod 3 outside the thrust bearing 5.
The course of work and the principle of present embodiment are:
Cooperate shown in Figure 1, earlier stator adpting flange 1 is screwed onto among the elastomer stator A with rectangular thread end 11, rotor connector 31 with screw rod 3 is screwed in the tube connector of rotor B again, put open sleeve 2 at screw rod 3 again, when sheathed, reaction torque slide block 32 is slipped in the opening chute 21 of open sleeve 2, then, with the left end ring flange 22 of open sleeve 2 and stator adpting flange 1 together with bolting, after again packing ring 4 being enclosed within on the screw rod 3 and the right-hand member ring flange 23 of open sleeve 2 with bolting together, again thrust bearing 5 is enclosed within on the screw rod 3; At last nut 6 is arranged on the screw rod 3, uses instrument rotation nuts 6 such as spanner, screw rod 3 is pulled out, and then rotor B is pulled out from elastomer stator A.
Reaction torque slide block 32 slides in the opening chute 21 of open sleeve 2, prevents that screw rod 3 from rotating, and then prevent that rotor B from rotating in the process of pulling out.
The setting of thrust bearing 5 is for reduction frictional force when rotating nut 6, and then laborsaving.
