Background technology
In the oil recovery process in oil field, oil pumping work is carried out in oil pumping polish rod upper and lower reciprocating motion in well head, for preventing the well head leakage of oil, need fixedly mount the packing box that is slidingly matched with oil pumping polish rod at well head.Desirable duty is that the axis and the well head center three of central axis, packing box of oil pumping polish rod is concentric.But oil pumping polish rod when location and installation because various reasons such as manufacturing, installation can produce some errors, cause the oil pumping polish rod central axis to have certain offset deviation in the top dead centre and the lower dead center of horse head motion, so that oil pumping polish rod is when the reciprocating motion of pumping, the axis of oil pumping polish rod and well head center line decentraction, thereby forming the oil pumping polish rod deflection tilts, cause that the eccentric wear phenomenon appears in packing in the common packing box, finally cause packing_seal to lose efficacy and leakage of oil contaminated environment.
At present, for solving the eccentric wear problem of oil pumping polish rod and packing box, generally used a kind of packing box that adopts the spherical hinge connection technology, this packing box can be adjusted eccentric phenomena in the swing in the angle of certain limit.As the patent No. is that the Chinese utility model patent manual of ZL02210388.0 discloses a kind of anti-eccentric wear packing box, should comprise pressure pad and packing on packing pressure cap, seal joint pressure cap, the packing by anti-eccentric wear packing box, socket spheroid packing box on the packing, be provided with the abrasionproof lining between spheroid packing box and the packing, the ball head of spheroid packing box is provided with seal joint, compress seal joint and be threaded with the seal joint pressure cap stuffing box shell and locknut.But, oil pumping polish rod is when moving back and forth, its central axis is actual to be the vertical line that constantly changes displacement in the motion, though the swing that packing box can be in certain angle, but the central axis of its axis and oil pumping polish rod meeting shape in an angle, still can cause the concentrated wear of oil pumping polish rod and packing box, form the packing box eccentric wear.
The utility model content
The purpose of this utility model is at above-mentioned defective, and a kind of anti-eccentric wear packing box is provided, that this anti-eccentric wear mechanism has is simple in structure, good seal performance, packing wearing and tearing evenly, advantage such as long service life.
The technical solution of the utility model is: a kind of anti-eccentric wear packing box, comprise the packing box body, axially offer the sucker rod passage in the box body, be provided with the packing that is sealed and matched with sucker rod in the packing box body, also include and be used for the pedestal that support is rotated assembling packing box body, the packing box body is provided with rotation transmission device, be provided with straight line/rotation transmission mapping device that axial driving force is provided by sucker rod in the packing box side, straight line/the output of rotation transmission mapping device is that unidirectional transmission cooperates with the input of rotation drive machine, on the input of straight line/rotation transmission mapping device and the sucker rod fixing one radially the transmission of roof pressure body cooperate.
Described straight line/rotation transmission mapping device comprises the engagement cover that cooperates by the rotation drive machine transmission with packing box, engagement cover top elasticity is the push rod that moves up and down synchronously with sucker rod of assembling vertically, and the push rod lower end is provided with and meshes the impact screw rod of the corresponding engagement fit of cover; Between the described straight line/output of rotation transmission mapping device and the input of rotation drive machine by push rod with impact between the screw rod or engagement cover and rotation drive machine between the one-way wheel mechanism that is provided with realize that unidirectional transmission cooperates.
Described push rod upper end is provided with buffer stopper and cooperates with roof pressure body roof pressure radially.
Offer the above screw thread of twice on the described impact screw rod, be installed with slide block on the described engagement cover inwall with described impact screw engages.
Described radially roof pressure body is the bump dish.
Described rotation transmission device constitutes by the gear ring of fixing assembling on the packing box with the driving gear of gear ring engagement assembling, and described driving gear rotates and is assemblied on the support that described pedestal side is connected.
Adopt said structure, anti-eccentric wear packing box of the present utility model is converted into rotatablely moving of driven wheel by push rod and straight line/rotation transmission mapping device with the rectilinear motion of sucker rod, and by the rotation of gear drive driving packing box, and make packing box do step rotation along a direction by one-way wheel mechanism, packing all keeps uniform wear with sucker rod on all directions, the eccentric wear phenomenon of sucker rod and packing box is solved completely, the replacement cycle of packing was extended for more than one month by an original week, it has not only reduced and has stopped the well time, increased the oil well output capacity, and reduced working strength of workers, the more important thing is and reduced well head leakage of oil pollution on the environment.
