2, avoid because packing compresses the well head leakage accident caused not in time, decrease environment pollution and economic loss brought thus, reduce cost of production.
3, eliminate wellhead equipment and pollute the potential safety hazard brought, improve production scene three and mark managerial skills, facilitate and carry out production strictly in line with rules and regulations.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of packing hold-down mechanism in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing in detail the utility model is described in detail, and unrestricted protection domain of the present utility model.See Fig. 1 and Fig. 2, oil pumping well packing automatic compacting device comprises ratchet spanner 2, pressing mechanism and packing hold-down mechanism 1, ratchet spanner 2 one end is connected with the connecting axle 6 of pressing mechanism, the other end is connected with the worm screw 12 of packing hold-down mechanism 1, pressing mechanism is fixed on packing hold-down mechanism 1 side, the lower end that support bar 8 lower end is fixed on the sleeve valve place of well head big four, upper end is supported on packing hold-down mechanism 1; Pressing mechanism is connected on the polished rod below polished rod eye by drive link 3, the worm gear 11 of packing hold-down mechanism 1 is fixed on the outside of packing box pressing cap 10.Pass drive link 3 when polished rod eye goes downwards to bottom dead centre, drive link 3 is forced to descending, compression pressing mechanism, stirs packing hold-down mechanism 1 by ratchet spanner 2, makes packing box pressing cap 10 rotate an angle, does a little fastening to the packing in box.Pressing mechanism comprises connecting axle 6, force-limit spring 4, back-moving spring 7 and fixed mount, and connecting axle 6 is connected by connecting pins in fixed mount with ratchet spanner 2, and back-moving spring 7 is arranged on the below of connecting axle 6 and ratchet spanner 2 junction; Force-limit spring 4 is fixed on the top of the connecting axle 6 above fixed mount, is positioned at the below of drive link 3, and the top of connecting axle 6 is provided with the top that gear cap is placed in drive link 3 connecting hole.Fixed mount is U-shaped frame, and back-moving spring 7 and connecting axle 6 are all arranged in fixed mount with the junction of ratchet spanner 2, and connecting axle 6 can slide in fixed mount; Spring base is equipped with in force-limit spring 4 lower end, is fixed on connecting axle 6 by this spring base.Connecting axle 6 can be connected by adjusting nut 5, to regulate the length of connecting axle 6, coordinates the installation of pressing mechanism.The steel wire diameter of force-limit spring 4 is greater than the steel wire diameter of back-moving spring 7, and its length is less than the length of back-moving spring 7.Packing hold-down mechanism comprises worm gear 11 and worm screw 12, worm gear 11 engages with worm screw 12, the shape of worm gear 11 centre bore conforms to the outer shape of packing box pressing cap 10, packing box pressing cap 10 is fixed wherein, worm gear 11 and worm screw 12 are arranged in shell 9, and the end that worm screw 12 stretches out shell 9 is provided with spanner side 13 and coordinates with the ratchet centre bore of ratchet spanner 2.Ratchet spanner 2 comprises ratchet and pawl, and ratchet is fixed on connecting rod one end and coordinates with ratchet, and the other end of connecting rod is fixed in connecting pins and is connected with connecting axle 6, and ratchet and spanner side 13 are fixed together.
This device is arranged between wellhead packing box and beam hanger for pumping machine, and positive left-hand thread rotates the length that adjusting nut 5 can regulate connecting axle 6, to adapt to different distance when various beam hanger for pumping machine runs to bottom dead centre and between wellhead packing box.Polished rod eye promotes drive link 3 when running to bottom dead centre and moves down, and by connecting axle 6, ratchet spanner 2 is rotated, thus worm gear 11 drives packing box pressing cap 10 to rotate, reaches the object compressing packing box.While drive link 3 moves down, back-moving spring 7 is compressed, storage power.During upstroke, polished rod eye departs from drive link 3, and back-moving spring 7 extends and makes drive link 3 moves, and ratchet spanner 2 also starts to reset, for next stroke is ready.Namely oil pumper completes a stroke, and this device just drives packing box pressing cap 10 to rotate a minute angle
.owing to having installed force-limit spring 4 in the upper end of connecting axle 6, when packing box pressing cap 10 compression puts in place, now the clamping torque of packing box pressing cap 10 is greater than the compression moment of force-limit spring 4, just force-limit spring 4 is compressed, and connecting axle 6 does not move down, such polished rod eye stroke that moves is an invalid stroke concerning this device.Only have when after packing wearing and tearing, when packing box needs to compress, when clamping torque is less than the compression moment of force-limit spring 4, force-limit spring 4 is no longer disabled compression, and connecting axle 6 can be driven to move down, and just can carry out compression action to packing box pressing cap 10.So just only when packing weares and teares, this device just action can compress packing, and when packing compression puts in place, this device can not undying compression packing.
