Description
Technical field
It the utility model is related to the design field of pumping unit horsehead hydraulic pressure pin extraction device.
Background technology
At present, the oil well of Jiangsu oilfield more than 95% is all pumping production, and the oil pumper used has following three kinds of models：
CYJ8、CYJ10、CYJ12.Because of oil pumper length of service from one to more than ten years, service life length；In recovery process, take out
The horse head of oil machine subjects various load and stress in up-down stroke, causes slight misalignment between pumping unit horsehead and walking beam to become
Shape；Such as heavy rain, heavy snow, strong wind, various bad weathers, cause horse head pin corrosion., it is necessary to which overturning horse head vacates operation before operation
Space, at present, write off method are to pound horse head pin with sledge hammer high-altitude, and work high above the ground, security is poor, write off is time-consuming, laborious, people
When work write off can not take out, or even also need to crane and could complete to turn over horse head work.
Utility model content
The utility model purpose is to be directed to problem above, there is provided a kind of safe, time saving and energy saving pumping unit horsehead
Hydraulic pressure pin extraction device.
The utility model includes suspension arrangement, jack, hand oil pump；Pass through height between the jack and hand oil pump
Pressure pipeline connects；The suspension arrangement includes upper connecting base, two connecting rods, two lower connecting bases, pegs；The upper connecting base
Both sides are respectively equipped with screw, and the upper end of two connecting rods is threaded in the screw of the upper connecting base of corresponding side respectively
And fixed by nut；A pair of linking arms, the lower end point of two connecting rods are symmetrical arranged in the jack upper periphery
Do not connected by corresponding lower connecting base and the linking arm of respective side；The peg is vertically installed in the top of upper connecting base, institute
State peg one end to be fixedly connected with upper connecting base center, the other end is provided with thread segment and is connected with upper horse head pin-and-hole by nut.
Manually hydraulic pump transmission power is very heavy to master for the utility model, is coordinated by suspension arrangement, easily taken out
Horse head pin.The utility model strikes the time pounded write off nail and save more than 50% than conventional, meets quick, the safe write off in scene
Operation, it is a kind of new, convenient, safe and reliable power tool.
The utility model sets a neck in the lower surface of the pair of linking arm respectively, in the week of the lower connecting base
Wall sets through hole, and the lower connecting base is placed on corresponding linking arm, and is placed in the neck of linking arm, the branch in stress
Frame and connection it is local indeformable.
The utility model sets pin-and-hole on the linking arm, in the outside of neck, and bearing pin is planted in the pin-and-hole, prevents
Only lower connecting base comes off, and strengthens security.
Two connecting rods described in the utility model are HY level 19mm pumping rod pipe nipples, disclosure satisfy that maximum bears active force.
