Abstract
The utility model relates to a well top polish rod load carrier, which is composed of a bearing connector, an upper adjusting barrel, a lower adjusting barrel, fixing screws, an adjusting board, a thrust bearing, an upper hanging rope board, a testing supporting block, a lower hanging rope board, lead caps, a steel cable and a polish rod. The utility model is characterized in that the polish rod is connected with the bearing connector through thread, the bearing connector is connected with the upper adjusting barrel or the lower adjusting barrel through thread, the upper adjusting barrel and the lower adjusting barrel are mutually spliced, the lower end of the lower adjusting barrel is pressed on the thrust bearing through the center hole of the adjusting board, the adjusting board and the thrust bearing are fixed on the upper hanging rope board through the fixing screws, the testing supporting block is supported between the upper hanging rope board and the lower hanging rope board, the steel cable penetrates the hanging rope holes at the both sides of the upper and lower hanging rope boards, and is hung at the hanging point of a horse head, the perfusion lead caps at the both ends of the steel cable is hung on the lower hanging rope board. The quadrate clamp is canceled in the utility model, and is replaced with the bearing connector, therefore the bearing area is enlarged, the cross shearing force is avoided, the vertical load force is enhanced, and the breaking and the dropping of the polish rod at the bearing points is reduced.
Description
One, technical field
The utility model relates to a kind of mechanical oil well well head load-bearing joint, specifically a kind of wellhead polish rod load-bearing device.
Two, background technology
Oil field machinery oil well great majority are beam pumping unit well and chain type oil pump well at present, and the drum type pumping unit well of minority is also arranged, and the well PRL of these wells is all transferred to oil pumper by hair plait polished rod eye and square clamp.Because the slips of square clamp and the stressed maximum in access section of polished rod, and lifting surface area only causes the pressure maximum between several slips teeth, therefore in oil pumper runs well, disconnected taking off often takes place in polished rod herein, cause the stopping production well workover, rate and the huge well workover fund of waste cause serious economy loss to the oil field when influencing the production of oil well.
Three, summary of the invention
The purpose of this utility model provides a kind of wellhead polish rod load-bearing device, and disconnected problem of taking off takes place the polished rod that solves above-mentioned prior art existence often.
The technical solution of the utility model realizes in the following manner:
The utility model is by the carrying joint, the adjusted tube, the following tube of regulating, fixed screw, adjustable plate, thrust bearing, last wire-hanging plate, back-up block is shown in survey, following wire-hanging plate, plumbous cap, wire rope and polished rod are formed, it is characterized in that polished rod is connected with the carrying joint screw thread, the carrying joint is threaded with adjusted tube or the following tube of regulating, peg graft between the up-down adjustment tube, following adjusting tube lower end is pressed on the thrust bearing by the adjustable plate centre bore, adjustable plate and thrust bearing are fixed on the wire-hanging plate with fixed screw, survey shows that back-up block is supported between wire-hanging plate and the following wire-hanging plate, steel wire penetrating is the outstanding rope hole on wire-hanging plate both sides up and down, be suspended on the horse head suspension point, the wire rope two ends are poured into plumbous cap and are hung over down on the wire-hanging plate.
The carrying joint is made as cylindrical, and top is provided with box thread, and periphery is provided with male thread, and the week side is provided with the wrench rib in the middle and upper part.
The adjusted tube is made as cylindrical shape, and interior week is provided with box thread, and the periphery middle part is provided with the wrench rib, and lower end week side is provided with protruding tongue.
Following adjusting tube be made as with the adjusted tube with interior external diameter tubular, the upper end is provided with the protruding tongue corresponding groove with the adjusted tube, is provided with box thread interior week or opens a vertical slot that is slightly larger than the polished rod diameter in periphery.
The utility model is compared with technology and is had the following advantages:
1, removed square clamp, replaced, increased loaded area, avoided cross shear, improved vertical load power, reduced polished rod and taken off the disconnected of the point of load with the carrying joint.
2, regulate stroke conveniently, when reducing stroke, adjust the crank-pin position, take away down and regulate tube, the adjusted cylinder base is got final product on thrust bearing.
3, be provided with thrust bearing, prevented wire rope beat turn round, disconnected taking off.
Four, description of drawings
Accompanying drawing is a mounting structure schematic diagram of the present utility model.
1-carrying joint 2-adjusted tube 3-regulates a tube 4-fixed screw 5-adjustable plate 6-thrust bearing 7-down and goes up wire-hanging plate 8-and survey and show the plumbous cap 11-of wire-hanging plate 10-polished rod 12-wire rope under the back-up block 9-among the figure
Five, the specific embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model by carrying joint 1, adjusted tube 2, down regulate tube 3, fixed screw 4, adjustable plate 5, thrust bearing 6, go up wire-hanging plate 7, survey show back-up block 8, wire-hanging plate 9, plumbous cap 10, wire rope 12 and polished rod 11 are formed down, it is characterized in that
Polished rod is connected with the carrying joint screw thread, the carrying joint is threaded with adjusted tube or the following tube of regulating, peg graft between the up-down adjustment tube, following adjusting tube lower end is pressed on the thrust bearing by the adjustable plate centre bore, adjustable plate and thrust bearing are fixed on the wire-hanging plate with fixed screw, survey and show that back-up block is supported between wire-hanging plate and the following wire-hanging plate, and steel wire penetrating is the outstanding rope hole on wire-hanging plate both sides up and down, be suspended on the horse head suspension point, the wire rope two ends are poured into plumbous cap and are hung over down on the wire-hanging plate.
Oil pumper when needing to increase stroke, is taken away down the adjusting tube and got final product in normal operation, during as the little stroke of need, adds down that regulating tube gets final product, and is easy to adjust, laborsaving, avoided the disconnected of polished rod to take off.
