Description
Technical field:
The utility model relates to oil pumper well head device, especially well head swing type sealer in the oil recovery field, oil field.
Background technology:
In the oil recovery process of oil field, the well head packing box is installed on the oil pumper well head, the packing that seals mutually with sucker rod is housed in the well head packing box, can when oil pumper is worked, avoid in the well liquid to overflow well and go out.Oil pumper works long hours and can make the packing wearing and tearing, gap between packing and the sucker rod increases, cause leakage, must change packing this moment, usually the old packing that prizes in the packing box with bottle opener when changing packing is at present changed, because it is less to lay the annular space of packing in the packing box, to waste time and energy when tripping out old packing, the normal oil recovery of influence produced.
The utility model content:
When changing packing, existing well head packing box trips out the deficiency that old packing is wasted time and energy in order to overcome, the utility model provides a kind of well head swing type sealer, this well head swing type sealer is very convenient when tripping out packing, has simple in structure and time saving and energy saving characteristics.
The technical solution of the utility model is: this well head swing type sealer comprises packing box, packing, connecting cylinder, bevel gear wheel, bevel pinion, rubber cushion, pressure pipe and cam, bevel gear wheel is meshed with the bevel pinion that is contained in the connecting cylinder sidewall, the silk braid of bevel gear wheel internal thread adapter sleeve outside sucker rod, packing places the silk braid top, be inlaid with bearing between bevel gear wheel and the connecting cylinder, the below of silk braid is inserted in the pressure pipe, the termination of bevel pinion has lead, the sidewall of silk braid has keyway, the end of lead places in the described keyway, and the contact surface of pressure pipe and cam is a concave surface.
Between the gear shaft of above-mentioned bevel pinion and the connecting cylinder sidewall cover is arranged, between the camshaft of cam and the connecting cylinder sidewall cover is arranged also; The packing box inwall is up big and down small taper seat.
The utlity model has following beneficial effect: owing to take such scheme, during packing in changing the well head packing box, rotate bevel pinion and drive the bevel gear wheel rotation, the drive silk braid moves upward, silk braid can eject the packing in the packing box, after old packing tripped out, the reverse rotation bevel pinion made silk braid get back to the packing box bottom, reinstalls new packing and gets final product.This apparatus structure is simple, and is very convenient, time saving and energy saving during packing in tripping out the well head packing box, improved operating efficiency.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-packing box among the figure, 2-packing, 3-bearing, 4-sucker rod, 5-bevel gear wheel, 6-silk braid, 7-connecting cylinder, 8-bevel pinion, 9-boss, 10-rubber cushion, 11-pressure pipe, 12-cover, 13-cam, 14-lead, 15-gear shaft, 16-camshaft.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this well head swing type sealer comprises packing box 1, packing 2, connecting cylinder 7, bevel gear wheel 5, bevel pinion 8, rubber cushion 10, pressure pipe 11 and cam 13, bevel gear wheel 5 is meshed with the bevel pinion 8 that is contained in connecting cylinder 7 sidewalls, the silk braid 6 of bevel gear wheel 5 internal thread adapter sleeves outside sucker rod 4, packing 2 places silk braid 6 tops, be inlaid with bearing 3 between bevel gear wheel 5 and the connecting cylinder 7, the below of silk braid 6 is inserted in the pressure pipe 11, the termination of bevel pinion 8 has lead 14, the sidewall of silk braid 6 has keyway, the end of lead 14 places in the described keyway, and pressure pipe 11 is a concave surface with the contact surface of cam 13, can avoid cam 13 displacements.Packing box 1 inwall is up big and down small taper seat, is easy to packing 2 and puts into or trip out.
During actual the use, during packing in changing well head packing box 1, shut down the first rotating cam 12 in back, cam 12 compresses the rubber cushion 10 of its below, and rubber cushion 10 back that is squeezed is out of shape and tightly is attached on sucker rod 4 outer walls, has sealed well head.Rotate bevel pinion 8 then and drive bevel gear wheel 5 rotations, drive silk braid 6 and move upward, silk braid 6 can eject the packing 2 in the packing box 1, and after old packing 2 tripped out, reverse rotation bevel pinion 8, silk braid 6 were got back to packing box 1 bottom, reinstalled new packing 2 and got final product.After packing 2 has been changed, backward rotation cam 12, rubber cushion 10 is loosened, and the interference fit between rubber cushion 10 and the sucker rod 4 is removed, but the oil pumper operate as normal.This apparatus structure is simple, and is very convenient, time saving and energy saving during packing 2 in tripping out well head packing box 1, improved operating efficiency.
