Abstract
The utility model discloses a pumping unit horsehead overturning device comprising a pumping unit walking beam and a pumping unit horsehead, wherein a revolving shaft horsehead pin as well as a prismatic steering bracket are arranged between the pumping unit horsehead and the pumping unit walking beam; one end of the steering bracket is fixed on the walking beam, the other end is connected with the horsehead through a connecting rod; the middle of the steering bracket is provided with a hydraulic cylinder; and a piston end of the hydraulic cylinder is connected with the steering bracket, and the other end is fixed on the walking beam. A steering hydraulic pipe and a reset hydraulic pipe are connected on the hydraulic cylinder, and the hydraulic cylinder is also provided with a stop valve. In the utility model, the hydraulic cylinder is utilized for replacing the traditional horsehead pin to fix the horsehead and a hydraulic pump is used as a power source to control the steering bracket to drive the horsehead to overturn, thus achieving the purpose of precluding the phenomenon that operators climb the horsehead to work at height. Compared with the prior art, the pumping unit horsehead overturning device has the advantages of being convenient in operation and safe to use, and reducing vehicle expenditures, and the like.
Description
Technical field
The utility model relates to upset pumping unit horsehead device when oil well is safeguarded in operation on the beam pumping unit mechanical oil recovery equip ment, particularly producing well of petroleum industry.
Background technology
Present on-the-spot mechanical oil well, last operation safeguard that when oil well carried out beam pumping unit upset horse head, operating personnel must climb up horse head dismounting horse head pin, because of there is very big potential safety hazard in work high above the ground, the accident of casualties take place repeatedly once.Long-term maintenance is not in place because scene length is stopped the well equipment part again, the nothing brake that has when resuming production, and what have does not come because of the corrosion horse head overturns, and must cause vehicle cost expenditure and produce delay with crane cooperation upset.
The utility model content
The technical problems to be solved in the utility model is for overcoming above-mentioned deficiency, and a kind of pumping unit horsehead turning device easy to operate, safe in utilization, simple in structure is provided.
The utility model is taked following technical measures: a kind of pumping unit horsehead turning device, comprise oil pumper walking beam, pumping unit horsehead, between pumping unit horsehead and the oil pumper walking beam rotating shaft horse head pin is installed, rib type turning rack also is installed between pumping unit horsehead and walking beam, turning rack one end is fixed on the walking beam, and the other end is connected with horse head by connecting rod, at the middle part of turning rack hydraulic cylinder is installed, the hydraulic cylinder piston end is connected with turning rack, and the other end is fixed on the walking beam.
Be connected with the steering hydraulic pipe and the hydraulic tube that resets on hydraulic cylinder, the steering hydraulic pipe and the hydraulic tube that resets are connected on the hydraulic pump.
At the steering hydraulic pipe with reset and between hydraulic tube and the hydraulic pump stop valve is installed.
The beneficial effects of the utility model are: utilize hydraulic cylinder to substitute fixedly horse head of traditional horse head pin, use hydraulic pump as power source, the control turning rack drives the horse head upset, stops the purpose that operating personnel climb horse head, work high above the ground thereby reach.Compared with prior art, have easy to operate, safe in utilization, reduce advantage such as vehicle expense expenditure.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, a kind of pumping unit horsehead turning device, comprise oil pumper walking beam 2, pumping unit horsehead 10, between pumping unit horsehead 10 and the oil pumper walking beam 2 rotating shaft horse head pin 15 is installed, rib type turning rack 5 also is installed between pumping unit horsehead 10 and walking beam 2, turning rack 5 fixed ends are fixed on the side of walking beam 2 by turning rack steady pin 6, and the other end is connected with connecting rod 8 by connecting pin 7, and connecting rod 8 is fixed on the side of horse head 10 by steady pin 9; At the middle part of turning rack 5 hydraulic cylinder 3 is installed, hydraulic cylinder piston 16 ends are connected the middle part of turning rack 5 by hydraulic cylinder piston steady pin 4, and hydraulic cylinder 3 fixed ends are fixed on the walking beam 2 by hydraulic cylinder steady pin 1.The steering hydraulic pipe 11 and hydraulic tube 12 1 ends that reset are connected on the hydraulic cylinder 3, and the other end installs stop valve 14 backs additional along walking beam 2 and oil pumper support 13 and is connected with the hydraulic pump on ground.
Concrete use is: earlier hydraulic pump is connected on the steering hydraulic pipe 11 during operation on the oil well, opening stop valve 14 suppresses, after power is passed to reciprocating hydraulic cylinder 3, eject piston 16, piston 16 pushes turning rack 5 simultaneously, makes turning rack 5 change forms, by connecting rod 8 drive horse heads 10 around the shaft pin 15 turn to a side, after reaching the purpose of upset horse head, close stop valve 14 and take off hydraulic pump.After treating that the oil well operation is finished, hydraulic pump is connected on the hydraulic tube 12 that resets, open on the stop valve 14 and suppress, power is passed to reciprocating hydraulic cylinder 3 and is made piston 16 withdrawal hydraulic cylinders, piston 16 spurs turning rack 5 simultaneously, push horse head 10 pin 15 rotations around the shaft by connecting rod 8, after horse head 10 resets, close stop valve 14 and take off hydraulic pump.
The utility model is designed to rotating shaft place that is connected that rib type turning rack is fixed on walking beam and horse head, utilizes hydraulic cylinder to push rib type turning rack, makes turning rack change form, turns to a side thereby drive horse head, reaches the upset horse head and carries out the purpose that well workover is safeguarded.Utilize hydraulic cylinder to substitute fixedly horse head of horse head pin, reach and remove a side horse head pin, stop the purpose that operating personnel climb horse head, work high above the ground.Because of being hydraulic drive, the operation of having avoided motor to get rid of horse head can be regulated arbitrarily, gets rid of the phenomenon of not coming over thereby stopped horse head.Save the operation of getting rid of horse head with crane simultaneously, reduced the expenditure of vehicle cost.
