Abstract
The utility model discloses a crank pin extractor of a hydraulic pumping unit, which comprises a hydraulic pump (1), a high-pressure rubber tube (2), a bracket (3), a hydraulic jack (4) and an auxiliary sleeve (5). The crank pin extractor of the hydraulic pumping unit is characterized in that the bracket (3) has an adjustable threaded structure, and an arc support plate is arranged at the upper end of the bracket (3) and located below the hydraulic jack (4); the auxiliary sleeve (5) which has a hollow cylindrical structure is located at the left end of the hydraulic jack (4); and the hydraulic jack (4) is connected with the hydraulic pump (1) through the high-pressure rubber tube (2). The crank pin extractor of the hydraulic pumping unit is simple in structure, convenient for operation, safe and reliable, not only the safe production of oil fields can be ensured, but also the time for changing a crank pin or adjusting the stroke can be shortened, the production rate of oil wells can be improved and the output of crude oil can be increased.
Description
Technical field:
The utility model relates to the oil-field oil pumper crank-pin and adjusts instrument, particularly is a kind of hydraulic oil pumping unit crank-pin extractor.
Background technology
At present, beam pumping unit is the oil field topmost production equipment that recovers the oil, in the operation process of oil pumper, because the bearing wear of crank pins can appear in the oil pumper long-term operation, the wearing and tearing of pin cover, damage phenomenon, after may wear to a certain degree, just must change pin or pin cover, to guarantee the steady safe handling of oil pumper, if do not change, oil pumper work is not steady, when serious pin can take place and deviate from, turn over the machine accident, cause heavy losses.When crank pins is changed at the scene, mainly be to stand in the method for knocking with sledgehammer on the reduction box pin is withdrawed from, because there is great unsafe factor in work high above the ground, inconvenient operation.The pin that in addition has is wasted time and energy during taking-up because long overlapping with pin of time combines closely, and labour intensity is big, has prolonged to stop the well time.When transferring the stroke operation, also cause the crank pins screw thread to damage easily, must repair button or change pin, prolonged the operating time more, influence crude oil production.
Summary of the invention
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of hydraulic oil pumping unit crank-pin extractor is provided.
The technical solution of the utility model comprises: hydraulic pump, high-pressure rubber pipe, support, hydraulic jack, auxiliary sleeve.Its support is adjustable helicitic texture, and the upper end is the circular arc supporting plate, be positioned at hydraulic jack below, the auxiliary sleeve of hollow circle tube structure is between the left end and crank-pin of hydraulic jack, hydraulic jack is a fulcrum with the reduction box base.Hydraulic jack is connected with hydraulic pump by high-pressure rubber pipe, manual operation hydraulic pump drive hydraulic jack, and power reaches auxiliary sleeve crank-pin is ejected.
The beneficial effects of the utility model are: simple in structure, easy to operate, safe and reliable, both guaranteed oilfield safety production, and can shorten the time of changing crank pins or transferring stroke again, rate when improving oil well production increases crude output.
Description of drawings
Accompanying drawing is the utility model The field schematic diagram.
1-hydraulic pump in the accompanying drawing, 2-high-pressure rubber pipe, 3-support, 4-hydraulic jack, 5-auxiliary sleeve, 6-crank-pin, 7-connecting rod, 8-crank, 9-reduction box base, 10-reduction box, 11-oil pumping unit base.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in accompanying drawing, hydraulic oil pumping unit crank-pin extractor is made up of hydraulic pump 1, high-pressure rubber pipe 2, support 3, hydraulic jack 4, auxiliary sleeve 5.Its support 3 is adjustable helicitic texture, and the upper end is the circular arc supporting plate, be positioned at hydraulic jack 4 below, the auxiliary sleeve 5 of hollow circle tube structure is positioned at the left end of hydraulic jack 4; Hydraulic jack 4 is connected with hydraulic pump 1 by high-pressure rubber pipe 2.
Method of operating
At first, oil pumping machine crank 8 is parked near bottom dead centre the position relative with reduction box base 9.
Secondly, lay down the nut of crank-pin 8.
The 3rd, support 3 is placed on the oil pumping unit base 11, hydraulic jack 4 is placed on the support 3, reduction box base 11 is withstood in hydraulic jack 4 bottoms, adjust support 3 height, hydraulic jack 4 centers and crank pins center are aligned, again auxiliary sleeve 5 one ends are enclosed within on hydraulic jack 4 plungers.The 4th, 1 pair of hydraulic jack 4 of operation hydraulic pump is suppressed, and makes auxiliary sleeve 5 other ends withstand crank-pin 6, continues to suppress, and crank-pin 6 can be ejected.
Claims (1)
1. an oil field hydraulic formula Crank Pin on Pumping Units extractor comprises: hydraulic pump (1), high-pressure rubber pipe (2), support (3), hydraulic jack (4), auxiliary sleeve (5); It is characterized in that: the support (3) of described hydraulic oil pumping unit crank-pin extractor is adjustable helicitic texture, the upper end is the circular arc supporting plate, be positioned at hydraulic jack (4) below, the auxiliary sleeve of hollow circle tube structure (5) is positioned at the left end of hydraulic jack (4); Hydraulic jack (4) is connected with hydraulic pump (1) by high-pressure rubber pipe (2).
