Abstract
The utility model relates to tools for oil well construction, in particular to a portable shearing device for a sucker rod. The portable shearing device adopts the structure that an oil cylinder body is connected with a hydraulic joint; a piston is arranged in the oil cylinder body; a plurality of piston strengthening posts and a blade connector are connected onto the piston; a blade is connected to the blade connector; the piston strengthening posts and the blade connector are all sleeved with piston return springs; the oil cylinder body is in threaded connection with a cutter main body; spring holes used for accommodating the piston return springs are formed in the cutter main body; a U-shaped cutting groove is formed in the front end of the cutter main body; the spring hole corresponding to the blade is communicated with the cutting groove through a blade outlet; a fixed blade is mounted on the cutter main body on two sides of the cutting groove through a fixing hole. The portable shearing device can be used for shearing the sucker rod safely, conveniently and fast with no generation of spark and less time and labor.
Description
Technical field:
The utility model relates to a kind of well construction power tool, particularly a kind of portable pumping rod cutter.
Background technology:
At present in construction operation process, often occurring causing because of sand card or wax card sucker rod to put forward phenomenon motionless or that do not open occurs, after sucker rod blocks, way has in the past been all the way of one of oil pipe hacksaw hand saws, in the middle of the process of saw, can produce spark, easily cause the accident, and do not meet the requirement of anti-explosion safety operation, worker saws a sucker rod approximately needs 20 minutes, and labour intensity is also very large.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of portable pumping rod cutter, and this device has been realized and can have been sheared safely, quickly and easily sucker rod, does not produce spark in work progress, time saving and energy saving.Having overcome existing sucker rod, to block rear employing hacksaw manual sawed-off, in the process of saw, can produce spark, easily cause the accident, and the deficiency wasting time and energy.
Technical solution adopted in the utility model is: a kind of portable pumping rod cutter, comprises oil cylinder body and cutter main body; Oil cylinder body connecting fluid crimp head, in oil cylinder body, be provided with piston, on piston, connect multiple piston righting posts and a blade connector, on blade connector, connect blade, on multiple piston righting posts and a blade, be all set with piston return spring, oil cylinder body and the screwed connection of cutter main body, cutter body interior is provided with the spring eye of laying piston return spring, cutter body front end is designed with U-shaped cutting groove, the spring eye of corresponding blade is connected with cutting groove by going out the edge of a knife, in the cutter main body of cutting groove both sides, by fixing hole, counteredge is installed.
The beneficial effects of the utility model are: the utility model is owing to having adopted hydraulic-driven blade to shear the mode of sucker rod, thereby have the function that can shear safely, quickly and easily sucker rod, do not produce spark in work progress, time saving and energy saving.
Brief description of the drawings:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
As shown in Figure 1, a kind of portable pumping rod cutter, comprises oil cylinder body 2 and cutter main body 11, oil cylinder body 2 connecting fluid crimp head 1, in oil cylinder body 2, be provided with piston 4, on piston 4, connect multiple piston righting posts 5 and a blade connector 6, on blade connector 6, connect blade 7, on multiple piston righting posts 5 and a blade 7, be all set with piston return spring 9, oil cylinder body 2 and 11 screwed connections of cutter main body, cutter main body 11 inside are provided with the spring eye 12 of laying piston return spring 9, cutter main body 11 Front-end Design have U-shaped cutting groove 10, the spring eye 12 of corresponding blade 7 is connected with cutting groove 10 by going out the edge of a knife 3, in the cutter main body 11 of cutting groove 10 both sides, by fixing hole 8, counteredge 13 is installed.Wherein piston righting post 5 plays the effect of stablizing righting piston 4, and piston return spring 9, after the complete pressure release of cutting, is responsible for the self-return of piston 4 and blade 7.
When the utility model uses, hydraulic joint 1 is connected with hydraulic hand-pump.Sucker rod to be cut is placed in U-shaped cutting groove 10, counteredge 13 is inserted in fixing hole 8, now sucker rod to be cut is just placed between blade 7 and counteredge 13.Press hydraulic hand-pump, utilize hydraulic drive piston 4, drive blade 7 to move ahead, coordinate sucker rod is cut off with counteredge 17.Hydraulic hand-pump bleeds off pressure, and piston 4 reclaims under the effect of piston return spring 9, and drives blade 7 to regain.Take down counteredge 17, now, cutting completes.
Be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model is not limited to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as meet, all within protection domain of the present utility model.
