Abstract
A pumping unit horse head fastening jackscrew is applied to fastening a pumping unit horse head pin. Two hexagonal nuts are connected to the adjusting screw rod, and the distance between the two hexagonal nuts is 100-150 mm; the outer walls of the two hexagonal nuts are respectively welded with a cuboid supporting block, and the two supporting blocks are the same in height. The effect is as follows: according to different models of pumping units, different horsehead pins are not flexible, fastening jackscrews are welded at the front end of a walking beam of the pumping unit, and adjusting screw rods are screwed, so that the horsehead of the pumping unit and the walking beam can be tightly connected together, the problem that the horsehead pin is not flexible for a long time is effectively solved, the horsehead and the walking beam are prevented from cracking and deforming, the equipment maintenance cost is saved, and the equipment guarantee is provided for crude oil production.
Description
Technical field
The utility model relates to oil field equipment maintenance technology field, the particularly loosening situation of pumping unit horsehead pin, and the isolated plant of fastening pumping unit horsehead pin is the fastening jackscrew of a kind of pumping unit horsehead.
Background technology
At present, most oil fields all adopt oil pumper to carry out oil extraction, and when the oil field is in when exploitation middle and later periods, because quite a few oil pumper has all passed through long-play, the horse head pin can produce loosening.The pumping unit horsehead pin is in loosening state for a long time; Along with fluctuating load is being born in the running of horse head uplink and downlink; Will be easy to occur breach at pumping unit horsehead pin and horse head junction, damage horse head, if equipment breakdown will take place in untimely discovery; There is potential safety hazard, even causes and shut down influence production.Need fastening pumping unit horsehead pin this moment, and horse head and walking beam can be linked together tightly, could normally move by assurance equipment.
The utility model content
The purpose of the utility model is: provide a kind of pumping unit horsehead fastening jackscrew, be welded on the preceding walking beam appropriate location of oil pumper, hold out against horse head with the adjusting screw mandrel, pumping unit horsehead and walking beam can be linked together tightly, assurance equipment normally moves.
The technical scheme that the utility model adopts is: the fastening jackscrew of pumping unit horsehead comprises two nuts, two back-up blocks and a set screw; An end of regulating screw mandrel has square column, can back-up wrench.It is characterized in that: be connected with two hex nuts regulating on the screw mandrel, the distance between two hex nuts is between 100～150mm; On the outer wall of two hex nuts, be welded with the back-up block of a cuboid respectively, the height of two back-up blocks is identical.
The specification of described hex nut is respectively M30; The specification of regulating screw mandrel is M30 χ 300mm; The thickness of rectangular back-up block is that 20mm, length are 100mm, and width is 100mm.
To regulate in two hex nuts of screw mandrel precession, two hex nuts will be welded on respectively on two back-up blocks, form a fastening jackscrew of pumping unit horsehead.Then the fastening jackscrew of this pumping unit horsehead is welded on oil pumper walking beam front end, all pads must firmly can sustain the top power of pumping unit horsehead.Screw and regulate screw mandrel and hold out against horse head.
The beneficial effect of the utility model: the fastening jackscrew of the utility model pumping unit horsehead, according to the different model oil pumper, different horse head pins is loosening; Fastening jackscrew is welded on the loose position of oil pumper walking beam front end horse head pin, and the adjusting screw mandrel of screwing can make pumping unit horsehead and walking beam closely link together; Effectively solving for a long time, horse head pin becomes flexible, the difficult problem of abnormal sound; Avoid horse head, walking beam craze and transfiguration, practice thrift the maintenance of equipment expense, for crude oil production provides the equipment assurance.
Description of drawings
Fig. 1 is the fastening jackscrew structural profile of a utility model pumping unit horsehead sketch map.
Fig. 2 is the A-A generalized section of Fig. 1.
Among the figure, 1-regulates screw mandrel, 2-nut, 3-back-up block.
The specific embodiment
Embodiment 1: with a fastening jackscrew of pumping unit horsehead is example, and the utility model is done further explain.
Consult Fig. 1.The fastening jackscrew of the utility model pumping unit horsehead comprises two nuts 2, two back-up blocks 3 and set screw 1.The specification of regulating screw mandrel 1 is M30 χ 300mm, and an end of regulating screw mandrel 1 has square column.On adjusting screw mandrel 1, be connected with two hex nuts 2, the specification of hex nut 2 is respectively M30.Distance between two hex nuts 2 is 120mm.The height of 3, two back-up blocks 3 of back-up block that on the outer wall of two hex nuts 2, is welded with a cuboid respectively is identical.The thickness of rectangular back-up block 3 is that 20mm, length are 100mm, and width is 100mm.
