Abstract
A crank hole bush detacher of pumping unit for mechanical oil ectraction comprises a crank, a crank hole bush, a draw nut and a draw threaded rod, wherein, the crank hole bush is arranged in the crank hole of the crank, the draw threaded rod is ripped into the crank hole bush, the large end of the draw threaded rod is suspended on the crank hole bush and the pin thread of the draw threaded rod screws with the female thread of the draw nut. When the utility model is used, the draw threaded rod or the draw nut is aswirl pulled to produce great axial force which easily draw the iron stained and transformational crank hole bush and the dismantlement of the crank hole bush of pumping unit is completed, causing no damage to the crank hole of pumping unit. Therefore, the crank hole bush detacher of pumping unit saves time and labor and is capable of having the iron stained and transformational crank hole bush dismantled quickly with low intensity of labor.
Description
One, technical field
The utility model is the oil pumping machine crank hole lining stripping attachment that a kind of oil field machinery oil is used.
Two, background technology
A plurality of crank holes are arranged on the crank of oil pumper, when needs one of are therein installed crank pins in the hole, at first the crank hole lining to be installed, be that the crank hole lining is arranged between crank and the crank pins, when oil pumper needs to change the crank hole lining after the crank hole lining damages at work, old crank hole lining need be removed, could more renew the crank hole lining, oil pumper is in the long-term work process, because the crank hole lining produces corrosion, distortion, make its crank hole lining difficult, even can't dismantle, after the long iron staff of employing slowly beats sometimes with existing common tool dismounting, remove with gas welding again, job schedule is slow, also damages oil pumping machine crank hole, oil pumper cisco unity malfunction easily.Therefore, adopt existing dismounting means, want the oil pumping machine crank hole lining of corrosion, distortion is disassembled, need expensive time and human and material resources just can finish this work, the shutdown of pumping machine time is long, and load is engaged in producing.
Three, summary of the invention
The purpose of this utility model is a design a kind of oil pumping machine crank hole lining stripping attachment, utilizes this oil pumping machine crank hole lining stripping attachment, can be easily the crank hole lining of corrosion, distortion be disassembled.
The purpose of this utility model is achieved in that it is made up of crank, crank hole lining, pulling nut, pulling screw rod.Crank, crank hole lining are the parts on the oil pumper.The crank hole lining is installed in the crank hole of crank, the pulling screw rod pierces in the crank hole lining, the big end of pulling screw rod is suspended on the crank hole lining, and the male thread of pulling screw rod screws with the box thread of pulling nut, and the pulling nut is in crank one side and contacts with crank.During use, rotation pulling screw rod or pulling nut reduce the distance between pulling nut and the crank hole lining, thereby the crank hole lining are pulled out, and finish oil pumping machine crank hole crank hole lining dismantlement work.
The beneficial effects of the utility model are: rotation pulling screw rod or pulling nut, and make it produce very big axial force, with the crank hole lining pulling of corrosion, distortion, under the situation of not damaging the oil pumping machine crank hole, finish oil pumping machine crank hole lining dismantlement work easily.Therefore, oil pumping machine crank of the present utility model hole lining stripping attachment can reach purpose of design, time saving and energy saving, operator's labour intensity is low, can be fast the crank hole lining of corrosion, distortion be disassembled, can remove the crank hole lining that to dismantle with common tool, can make oil pumper meet the requirements of duty.
Four, description of drawings
Accompanying drawing is the installation diagram of the utility model embodiment.
Five, the specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described.
Among the figure: the 1st, crank, the 2nd, crank hole lining, the 3rd, pulling nut, the 4th, pulling screw rod.Be that the utility model is made up of crank 1, crank hole lining 2, pulling nut 3, pulling screw rod 4.Crank 1, crank hole lining 2 are the parts on the oil pumper.Crank hole lining 2 is installed in the crank hole of crank 1, pulling screw rod 4 pierces in the crank hole lining 2, the big end of pulling screw rod 4 is suspended on the crank hole lining 2, and the male thread of pulling screw rod 4 screws with the box thread of pulling nut 3, and pulling nut 3 is in crank 1 one sides and contacts with crank 1.During use, rotation pulling screw rod 4 or pulling nut 3 reduce the distance between pulling nut 3 and the crank hole lining 2, thereby crank hole lining 2 are pulled out, and finish the dismantlement work of oil pumping machine crank hole crank hole lining 2.
