Abstract
The utility model relates to a pumping rod cutter, which belongs to the technical field of the oil downhole operation equipment and relates to a device for cutting a pumping rod. The pumping rod cutter comprises a U-shaped main body. The outside of the bottom of the U-shaped main body is connected with a hydraulic cylinder. The inside of the bottom of the U-shaped main body is provided with a moving cutter body. The rear end of the moving cutter body is connected with a piston rod of the hydraulic cylinder. A fixed cutter body opposite to the moving cutter body is arranged between two arms of the U-shaped main body. One end of the fixed cutter body is movably connected on one arm of the U-shaped main body by a pin, while the other end thereof is provided with a pawl. The other arm of the U-shaped main body is provided with a dismountable locking mechanism matched with the pawl. The moving cutter body and the fixed cutter body are respectively provided with a cutter blade. The pumping rod cutter can conveniently cut the pumping rod with less effort.
Description
Technical field
The utility model relates to a kind of sucker rod clipper that is suspended on the underground work derrick, belongs to oil downhole operation equipment technical field.
Background technology
Under oil well in the operation process, owing to reasons such as the cured sand cards of knot, through regular meeting pumping rod fasterner takes place and work the situation of not coming out in oil pipe, at this moment need the stretch bending sucker rod that it is cut off, not only inconvenience but also dangerous did not also have proprietary equipment to address this problem so far.
The utility model content
The purpose of this utility model is to provide a kind of sucker rod clipper that is suspended on the workover derrick, when needs cut off sucker rod, pushes it against sucker rod, with the clipper locking, suppresses the back and just can cut off sucker rod very easily.
The purpose of this utility model is achieved in that a kind of sucker rod clipper, comprise the U-shaped main body, the described U-shaped bottom part body outside connects hydraulic cylinder, described U-shaped bottom part body inboard is provided with the moving knife body, the rear end of described moving knife body connects the piston rod of hydraulic cylinder, the stationary knife body relative with the moving knife body is set between U-shaped main body two arms, described stationary knife body one end is movably connected on the arm of U-shaped main body by bearing pin, the other end of described stationary knife body is provided with pawl, the dismountable type locking mechanism that cooperates with described pawl is set on another arm of described U-shaped main body, on described moving knife body and the stationary knife body blade is housed respectively.
The utility model is suspended on the derrick, when needing to shear sucker rod, pushes sucker rod to, make sucker rod between moving knife body and stationary knife body, compression hydraulic cylinder promotes moving knife body and stationary knife body closure, cuts off sucker rod convenient and strength-savingly.
For the utility model being suspended on the derrick, on the described U-shaped main body suspension ring are set by rope.
Described hydraulic cylinder is the single-acting type hydraulic cylinder that automatically resets.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Wherein, 1-U shape main body, 2-stationary knife body, 3-bearing pin, 4-dismountable type locking mechanism, 5-pawl, 6-blade, 7-moving knife body, 8-suspension ring, 9-hydraulic cylinder.
The specific embodiment
As figure, a kind of sucker rod clipper, comprise U-shaped main body 1, U-shaped main body 1 bottom outside connects hydraulic cylinder 9, U-shaped main body 1 bottom inside is provided with moving knife body 7, the rear end of moving knife body 7 connects the piston rod of hydraulic cylinder 9, the stationary knife body 2 relative with moving knife body 7 is set between 1 liang of arm of U-shaped main body, stationary knife body 2 one ends are movably connected on the arm of U-shaped main body 1 by bearing pin 3, the other end of stationary knife body 2 is provided with pawl 5, the dismountable type locking mechanism 4 that cooperates with pawl 5 is set on another arm of U-shaped main body 1, on moving knife body 7 and the stationary knife body 2 blade 6 is housed respectively.
The utility model is suspended on the underground work derrick, when needs are sheared sucker rod, push the utility model to sucker rod, then stationary knife body 2 is locked by dismountable type locking mechanism 4, at this moment suppress to the single-acting type hydraulic cylinder 9 that automatically resets, promote 7 translations of moving knife body by piston rod, blade 6 cuts off sucker rod, cut off sucker rod after, draw back dismountable type locking mechanism 4, withdraw from sucker rod, 2 of stationary knife bodies are opened simultaneously, and entire work process is convenient and labor-saving.
