Abstract
The utility model discloses a horsehead fixed pin hydraulic lifting apparatus of a pumping unit device for extracting oil. The utility model is mainly characterized in that a hydraulic cylinder is positioned on the lower beam of a carrier which is connected through a high-pressure hose which forms a return circuit through coming and going with a hydraulic station which contains hydraulic oil and drives the oil pump by a generator, and a hand exchange valve is provided between the hydraulic cylinder and the hydraulic station. The utility model has the advantages of proper structure and convenient operation, and being capable of lifting the horsehead fixed pin of a pumping unit safely, reduce in work and unsafe and potential factors.
Description
Affiliated technical field:
The horse head steady pin that the utility model relates to a kind of oil pumper equipment of oil extraction use trips out device, and particularly a kind of hydraulic machinery trips out device, when being suitable for displacement of oil pumper equipment or maintenance, and the operation that the horse head steady pin can trip out easily.
Background technology:
At present, technique known is, tripping out of pumping unit horsehead pin, be to get from the bottom up with sledgehammer in 6 meters high high-altitudes by the workman, effort, dangerous, careless slightly workman will fall down from the high-altitude, and casualty accident constantly takes place, and is hard nut to crack that does not have solution for many years in the oil recovery workover treatment.
Summary of the invention:
For the deficiency of the technology that trips out that overcomes existing pumping unit horsehead pin, the utility model provides a kind of horse head steady pin hydraulic pressure to trip out device, and this device is used for the operation that oil pumper equipment horse head steady pin can trip out easily.
The technical scheme that its technical problem that solves the utility model adopts is: make a hanger, design and installation hydraulic cylinder on the underbeam of hanger, the high-pressure rubber pipe that constitutes the loop by turnover with hydraulic oil be housed be connected with Hydraulic Station with the oil pump of motor, be equipped with therebetween and manually change a valve connection and constitute.During use, shoulder with the horse head steady pin is the location, in horse head pin-and-hole seat upper end surface, the hanger body is installed, turn right and move hand-operated direction valve, under the hydraulic oil effect that Hydraulic Station is supplied with, hydraulic cylinder piston rod rises, and the horse head pin is ejected walking beam hole seat and horse head hole seat, after tripping out the horse head pin, turn left to move hand-operated direction valve, hydraulic cylinder piston rod decline return is promptly finished whole operations.
The beneficial effects of the utility model are: can trip out the horse head steady pin of oil pumper safely, reduce labor operation and hidden danger factor.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
1, Hydraulic Station, 2, manually change a valve, 3, high-pressure rubber pipe, 4, hanger, 5, hydraulic cylinder, 6, associated part walking beam horse head pin-and-hole seat, 7, associated part horse head pin-and-hole seat, 8, associated part horse head pin.
The specific embodiment:
Referring to Fig. 1, make a hanger (4), design and installation hydraulic cylinder (5) on the underbeam of hanger (4), the high-pressure rubber pipe (3) that constitutes the loop by turnover with hydraulic oil be housed be connected with Hydraulic Station (1) with the oil pump of motor, be equipped with therebetween and manually change a valve (2) connection and constitute.During use, shoulder with horse head associated part horse head pin (8) is the location, in associated part horse head pin-and-hole seat (7) upper end surface, the hanger body is installed, turn right and move hand-operated direction valve (2), under the hydraulic oil effect that Hydraulic Station (1) is supplied with, the piston rod of hydraulic cylinder (5) rises, the horse head pin is ejected associated part walking beam horse head pin-and-hole seat (6) and associated part horse head pin-and-hole seat (7), after tripping out associated part horse head pin (8), turn left to move hand-operated direction valve (2), the piston rod decline return of hydraulic cylinder (5) is promptly finished whole operations.
