Abstract
A novel valve type rope hanger comprises a baffle plate, shaft sleeves, shafts, opening pins and a rope hanger. A polished rod baffle plate which is fixed through a screw and arranged on one side of the rope hanger provided with a polished rod groove is detached, a valve is then disposed on the rope hanger, the valve consists of the shaft sleeves and the baffle plate, each of the shaft sleeves at two ends of the valve is divided into an upper section, a middle section and a lower section, the upper sections and the lower sections of the shaft sleeves are welded with two ends of the side of the rope hanger with the polished rod groove, the middle sections of the shaft sleeves are welded with two ends of the baffle plate, the shafts are inserted into the shaft sleeves at two ends, the opening pins are inserted into shaft holes, and the valve can be opened by taking out the shaft at an optional end. The valve type rope hanger has the advantages of simple and convenient operation, safety and reliability without corrosion of rainwater or the influence of external environment.
Description
Technical field: the utility model relates to a kind of oil pumper shutter-type polished rod eye, belongs to oil field machinery oil equipment part field.
Background technology: oil pumper is the capital equipment that field produces is used, polished rod eye is the vitals that oil pumper is connected with downhole pump by polished rod, work under the oil pumper lowered in field environment, be subjected to all the year round wind and weather each the parts connecting screw is perishable gets rusty, polished rod baffle plate on the existing polished rod eye is to be fixed on the polished rod eye with two screws, is difficult for the defective that pine is unloaded after having that intensity is low and being corroded, make troubles for construction and operation, also exist unsafe factor simultaneously.
Summary of the invention: for the screw intensity that solves fixed dam on the existing polished rod eye is hanged down with dangerous, tool using when pine is unloaded, the defective that is awkward again after getting rusty, a kind of shutter-type polished rod eye of this new design, promptly increased baffle plate intensity and guaranteed safety, not only handled easily but also without instrument.
The technical scheme that its technical problem adopted that the utility model solves is: polished rod eye is had polished rod groove one side remove with the fixing polished rod baffle plate of screw, a valve is installed, wherein polished rod eye is whole, in the middle of one side of polished rod eye is the polished rod groove, it in the middle of the two ends of polished rod eye the steel wire rope groove of symmetry, one end of steel wire rope groove is the plumbous head-room of symmetry, valve is by baffle plate, axle sleeve, axle is formed, the two ends axle sleeve of valve is divided into three sections of upper, middle and lowers, the two sections of axle sleeve and polished rod eye have the two ends welding of polished rod groove one side, the interlude of axle sleeve and the welding of baffle plate two ends, axle inserts in the axle sleeve at two ends, cottor pin is inserted in the axis hole, takes out the axle valve of any end and just can open.
The invention effect: the utility model is not subjected to the corrosion of rainwater and the influence of external environment, need not tool using when constructing operation, takes out any end axle and just can open the polished rod baffle plate, and is easy to operate and safe reliable.
