Abstract
The utility model relates to a flange jacking device, particularly to a plunger assembly square flange jacking device for plunger pumps. The device consists of a security gasket and a jacking device, wherein the jacking device comprises a first supporting plate, a second supporting plate, a center bolt and jackscrews; four bulges matched with holes of an assembly square flange are formed on the circumferential surface of the security gasket, and the included angle formed by every two adjacent bulges is 90 degrees; and a first through hole is formed in the center of the first supporting plate, a second through hole is formed in the center of the second supporting plate, a screw hole is formed in each of two ends of the second supporting plate, the first supporting plate and the second supporting plate are connected rotationally through the center bolt, the jackscrews are in threaded connection in the screw holes, and the length of the first supporting plate is identical with the inner diameter of the assembly square flange. The device is simple in structure, convenient to operate, flexible, practical and capable of greatly reducing the labor intensity of workers and improving the pump starting time efficiency.
Description
Technical field
The utility model relates to a kind of flange top and gets device, and specifically device is got on the blue top of a kind of plungers pump plunger assembly method.
Background technology
After oil field oil flow production finishes, need to carry out secondary recovery to oil-bearing stratum flooding.Oil field is used the rear water filling of high pressure piston pump pressurization of three plungers or five plungers to supplement stratum energy for a long time.Plunger displacement pump in use, generally only just dismantle when the mat at assembly for plunger rear portion goes wrong by assembly for plunger square flange.Owing to not dismantling over a long time, when the mat at assembly for plunger rear portion goes wrong, because corrosion in water causes assembly for plunger square flange together with pump housing corrosion, assembly method orchid cannot be taken out from the pump housing.Operating personnel in order to take out square flange from the pump housing, generally to adopt thick crowbar to be inserted between assembly for plunger, the thick crowbar that moves around clashes into assembly pressure cap, utilize assembly pressure cap to drive assembly active methods orchid, because the gap between assembly is little, crowbar operating range is little, prizes and clashes into assembly pressure cap process effort, time-consuming.
Utility model content
The utility model is intended to address the above problem, and provides the blue top of a kind of plungers pump plunger assembly method to get device, and it is simple in structure, easy to operate, flexibly practical, can greatly reduce workman's labour intensity, rate while improving turn on pump, and its technical scheme adopting is as follows:
Device is got on the blue top of a kind of plungers pump plunger assembly method, by safe pad and top, get installation composition, described top is got device and is comprised the first gripper shoe, the second gripper shoe, centre bolt and jackscrew, on the circumferential surface of described safe pad, be formed with four projections that match with the eyelet of assembly method orchid, angle between adjacent protrusion is 90 degree, described the first gripper shoe center has the first through hole, the center of described the second gripper shoe has the second through hole, the place, two ends of described the second gripper shoe respectively has a silk hole, described the first gripper shoe and the second gripper shoe are rotationally connected by centre bolt, described jackscrew is threadedly connected in a hole, the length of described the first gripper shoe is identical with the internal diameter of assembly method orchid.
The utlity model has following advantage: simple in structure, easy to operate, practical flexibly, reduced largely workman's labour intensity, rate while having improved turn on pump.

The specific embodiment
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As shown in Figures 1 to 5, device is got on the blue top of a kind of plungers pump plunger assembly method of the present embodiment, by safe pad 1 and top, getting device 3 forms, described top is got device 3 and is comprised the first gripper shoe 4, the second gripper shoe 5, centre bolt 6 and jackscrew 7, on the circumferential surface of described safe pad 1, be formed with four projections 2 that match with the eyelet of assembly method orchid, angle between adjacent protrusion 2 is 90 degree, described the first gripper shoe 4 centers have the first through hole 10, the center of described the second gripper shoe 5 has the second through hole 9, the place, two ends of described the second gripper shoe 5 respectively has a silk hole 8, described the first gripper shoe 4 and the second gripper shoe 5 are rotationally connected by centre bolt 6, described jackscrew 7 is threadedly connected in a hole 8, the length of described the first gripper shoe 4 is identical with the internal diameter of assembly method orchid.
During use, the journey emptying of flowing backwards after the plunger displacement pump termination of pumping of the assembly method orchid that will dismantle, pull down plunger side's clamp, assembly for plunger and assembly for plunger fixed screw, safe pad 1 is arranged on the eyelet position that pump head plunger moves, device 3 is got in top to be assembled, after the inner chamber of inclination insertion assembly method orchid, set level, launch the first gripper shoe 4 and 5 one-tenth of the second gripper shoes " ten " font, the first gripper shoe 4 is withstood the blue inwall of assembly method, the second gripper shoe 5 is withstood two arc chord angles of assembly method orchid, alternately rotate jackscrew 7 with spanner, jackscrew 7 withstands on safe pad 1, give 5 one of the second gripper shoes power backward, assembly method orchid is moved backward under the promotion of the second gripper shoe 5, finally from the pump housing, departed from whole dismantlement work.
With way of example, the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
