Abstract
The utility model relates to a kind of adjusting stroke of beam-pumping unit and pulls out crank pins hydraulic means.Mainly solve and extract crank pins and need manpower to pound out to waste time and energy and the problem that there is potential safety hazard.Described hydraulic cylinder (1) two ends are separately installed with expansion link (2), hydraulic cylinder (1) is connected with manual pump (6) by hydraulic line (4), hydraulic cylinder (1) top is also provided with suspension ring (3), described manual pump (6) is provided with the action bars (5) matched, manual pump (6) is also sealed and installed with reversal valve (7) and Pressure gauge (8).Have easy to operate, safe and reliable feature.
Description
Technical field
The utility model relates to oil pumper specific purpose tool field, and specifically a kind of adjusting stroke of beam-pumping unit pulls out crank pins hydraulic means.
Background technology
It is all that artificial sledgehammer operates that adjusting stroke of beam-pumping unit pulls out crank pin, due to the running of crank pins long-term load, crank pins and axle sleeve are sticked together, workman is pounded crank pin and is exertd great efforts and also very difficultly pound, security incident may occur at any time, meanwhile, operative also may smash crank pin screw thread, such intelligence is changed, and has both added the labour intensity that entreprise cost turn increases workman.
Utility model content
For solve in background technology exist pull out crank pin difficulty and workman's write off axle time sledgehammer easily cause danger and easily smash the problem of the problem of screw thread, the utility model proposes a kind of safe and reliable, ensure safety of workers, time saving and energy saving adjusting stroke of beam-pumping unit pulls out crank pins hydraulic means.
The technical scheme that the utility model adopts is: described hydraulic cylinder two ends are separately installed with piston rod, piston rod is by screwed connection expansion link, described expansion link merogenesis is arranged, often pass through screwed connection between joint, hydraulic cylinder is connected with manual pump by hydraulic line, also be provided with suspension ring above hydraulic cylinder, described manual pump be provided with the action bars matched, manual pump is also sealed and installed with reversal valve and Pressure gauge.
The beneficial effects of the utility model are: owing to have employed the technical scheme that the utility model adopts, be applied in regulating stroke of oil pumping well, easy to operate, decrease the labour intensity of operator, safe and reliable, improve operating efficiency, can smoothly crank pins be extracted, and evil does not damage crank pin screw thread, ensure that and adjust completing smoothly of ginseng work.
Accompanying drawing explanation
Fig. 1 is the utility model organigram.
In figure, 1-hydraulic cylinder, 2-expansion link, 3-suspension ring, 4-hydraulic line, 5-action bars, 6-manual pump, 7-reversal valve, 8-Pressure gauge.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of adjusting stroke of beam-pumping unit as shown in Figure 1 pulls out crank pins hydraulic means, described hydraulic cylinder 1 two ends are separately installed with piston rod, piston rod is outward by screwed connection expansion link 2, described expansion link 2 merogenesis is arranged, often pass through screwed connection between joint, can lengthen arbitrarily and shorten expansion link 2, adapt to not same crank, hydraulic cylinder 1 is connected with manual pump 6 by hydraulic line 4, suspension ring 3 are also provided with above hydraulic cylinder 1, described manual pump 6 is provided with the action bars 5 matched, manual pump 6 is also sealed and installed with reversal valve 7 and Pressure gauge 8.
Concrete, in use, be first parked in by oil pumping machine crank and reduction box vertical direction, specific works step is as follows;
1st step: first hydraulic cylinder 1 is hung on protection crank device by suspension ring 3;
2nd step: the end cap of crank pins and the nut of crank pins are unloaded;
3rd step: connection expansion link 2 correspondence of hydraulic cylinder 1 is withstood on crank pins;
4th step: shock-proof pressure gauge 8 is contained on manual pump 6, then checks whether sealing;
5th step: hydraulic line 4 is connected on hydraulic cylinder 1 and manual pump 6;
6th step: the action bars 5 pairs of hydraulic cylinders 1 picking up manual pump 6 circulate pressurization, are pressurized to certain pressure, the expansion link of hydraulic cylinder 1 just by crank pin top out.
