Abstract
The utility model relates to a linear oil pumping device, belonging to the field of oil equipment. In prior art when oil well is on working through frame-type linear oil pumping device, the head frame of the oil well need to be returned and replaced to provide well head with spaces, and other devices are necessary to support that is time wasting and inefficient. The utility model provides a well place-off device for the linear oil pumping device, with that the well frame does not need to move away for the place of the well head. The utility model mainly comprises a bracket, leading wheels, hoisting ropes, bracket turnover wheels, an inclined holder for the turnover of the bracket, a hoister, gemels, positioning pins and the shaft of the gemels. The gemels are arranged behind the leading wheels bracket; the positioning pins are arranged in the middle of the leading wheels bracket; the hoisting rope is connected with leading wheels bracket for certain head, and with the hoisting device and gemel shaft for other head through turnover bracket as a fulcrum; the leading wheels bracket is lifted through dynamoelectric or manual chain inverting operation for providing space above the well head.
Description
Technical field
The utility model belongs to the oil recovery machiner equipment technical field, particularly relates to a kind of linear oil pumping machine by the well device.
Background technology
At present, external long stroke pumping unit development both at home and abroad rapidly, representative is U.S. ROTAFELEX long stroke pumping unit, and the LCJ-250 type long stroke pumping unit of China's exploitation, this rod-pumped well top of the trellis is provided with a head sheave, is twining wire rope one end on the head sheave and is being connected with power set, and an end is connected with beam hanger also and well center is adjusted to a vertical line, this vertical line and head sheave are tangent, and the point of contact is called suspension point; Head sheave is done reciprocal rotation, drives beam hanger and the oil pump pumping crude oil that moves up and down.After oil well operation a period of time, need carry out well workover, get rid of the oil well fault, generally reaching well head by the well maintenance vehicle that has derrick, head sheave, lifting means carries out workover treatment, one one of beam hanger in the oil well is proposed or transfer, therefore the head sheave of oil pumper must be got out of the way the well head vertical line position, avoids interfering with the head sheave of well maintenance vehicle.Workover treatment finishes, and the head sheave of oil pumper also will reset, and continue to drive beam hanger and the oil pump pumping crude oil that moves up and down.General oil well well workover in a year 3～5 times, so allow well, the operation that resets of oil pumper are recurrent.Present linear oil pumping machine by well, resetting needs power-equipment to drag more than 20 ton whole the moving of derrick, mechanism's complexity, reseting precision be poor, waste time and energy, poor stability, cost are also higher.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, be engaged in oil pumper developmental research and long-term practice for many years through the inventor, a kind of simple in structure, smooth operation, reseting precision height be provided, do not need power-equipment to drag the whole linear oil pumping machine that moves of derrick by the well device.
The linear oil pumping machine that the utility model provides is characterized in that comprising directive wheel support (1), directive wheel (2) pull rope (3), turnover bracket wheel (4), turnover bracket (5), turnover bracket bearing diagonal (6), tractor (7), hinge (8), oil pumper upper mounting plate (9), alignment pin (10), hinge axis (11) maintenance pedal (12) by the well device.Described directive wheel support (1) is welded to form by i iron, and the rear portion is provided with hinges (8), hinge axis (11), and the directive wheel support can rotate up, and the middle part is provided with alignment pin (10), guarantees positioning accuracy.Described turnover bracket (5) can serve as that the axle rotation is upright with hinge axis (11), but also level was fallen as the inspection platform use, was supported by bearing diagonal (6) when turnover bracket (5) is upright, and two ends connect with bolt.Described pull rope (3) is made up of wire rope or traction belt, and an end is connected with directive wheel (2), and an end is connected with tractor (7), hinge axis (11).Described tractor (7) can be with electronic or manual chain hoist.Tractor (7) one ends connect pull rope (3), and an end connects hinge axis (11).
The linear oil pumping machine that provides according to the utility model is provided with alignment pin by in the well device, guarantees repetitive positioning accuracy, does not need power-equipment to drag whole the moving of derrick and can get out of the way well head.Reliability height, efficient height, cost are low, good operability.
