Description
Technical field
The utility model relates to a kind of handling drilling pipe box cupling or joint, particularly relates to a kind of sucker rod slips.
Background technology
At present, conventional sucker rod external diameter is about 28mm, and first, its less external diameter generally can only use button and shackle on common pipe wrench, not only requires great effort, and expends the activity duration; Secondly, use hydraulic tongs to load sucker rod if want, but because of the application diameter comparatively large (about 140mm) of hydraulic tongs cannot with fastener for sucker rod closed-bite maloccllusion.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of sucker rod slips of new structure, make it have more value in industry.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide the sucker rod slips that a kind of convenient disassembly, safety are high, significantly can reduce labour intensity, improve handling sucker rod efficiency.
Sucker rod slips of the present utility model, in order to hold sucker rod, comprise cylindrical body, described cylindrical body comprises the slips of two " C " types, the inner side of described each slips all offers card tooth, and the card tooth of two described slips encloses the clamping chamber forming the described sucker rod of clamping mutually, described each card tooth is in axial direction divided into clamping part and two tooth portions, described two tooth portions are separately positioned on the both sides of clamping part, described clamping part has the arc clamping face of inner concave shape, described each tooth portion convexly stupefiedly to form by some that are longitudinally provided with, described some convex stupefied be spliced to form stepped, one end of described two slips is rotationally connected, the other end is connected by securing member.
Further, described two slips are connected by rotating shaft.
Further, described securing member is bolt,
Further, described card tooth is provided with carburized layer.
By such scheme, the utility model at least has the following advantages: one, structure design is simple, can doubling folding to be arranged on so that hydraulic tongs buckling procedure on sucker rod, convenient disassembly, improves handling sucker rod efficiency; Two, adopt convex stupefied linear contact lay and arc clamping plane-plane contact between Ka Ya and sucker rod, have and be well engaged effect, and uniform force, face contact can not make sucker rod surface leave surperficial hard defects; Three, the design of cylindrical body convenient with hydraulic tongs with the use of, significantly can reduce labour intensity, improve operating efficiency.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of manual, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.

Fig. 1 is the structural representation of the utility model sucker rod slips;
Fig. 2 is the structural representation of the first slips in Fig. 1;
Fig. 3 is Fig. 2 neutral body structural representation;
Fig. 4 is the structural representation of the second slips in Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
See Fig. 1-4, a kind of sucker rod slips of the utility model one preferred embodiment, in order to hold sucker rod, comprise cylindrical body, cylindrical body comprises the slips of two " C " types, i.e. the first slips 1 and the second slips 2, the inner side of the first slips 1 and the second slips 2 all offers card tooth, and the first slips 1 and the card tooth of the second slips 2 enclose the clamping chamber 3 forming clamping sucker rod mutually, each card tooth is in axial direction divided into clamping part 13 and two tooth portions 12, two tooth portions 12 are separately positioned on the both sides of clamping part 13, clamping part 13 has the arc clamping face of inner concave shape, each tooth portion 12 forms by some that are longitudinally provided with convex stupefied 121, some convex stupefied 121 be spliced to form stepped, one end of the 12 liang of slips in two tooth portions is rotationally connected, the other end is connected by securing member.The structure design of the utility model sucker rod slips is simple, can doubling folding to be arranged on so that hydraulic tongs buckling procedure on sucker rod, convenient disassembly, improves handling sucker rod efficiency; Card tooth and the way of contact adopting convex stupefied 121 linear contact lay and arc to clamp plane-plane contact between sucker rod to combine, have and be well engaged effect and uniform force, face contact can not make sucker rod surface leave surperficial hard defects, in order to avoid excessive injured sucker rod ruptures and occurs that sucker rod falls into the danger in well under repetitive stresses effect; The design of cylindrical body convenient with hydraulic tongs with the use of, significantly can reduce labour intensity, improve operating efficiency.
One end of first slips 1 of sucker rod slips is provided with the first axle bolt 11, corresponding one end of second slips 2 is provided with the second axle bolt 21 matched with the first axle bolt 11, first axle bolt 11 is connected by rotating shaft with the second axle bolt 21, manufacture the first slips 1 and the second slips 2 material used is drill pipe of oil well joint special-purpose steel, intensity is high, long service life, and slips has sizes to clamp the sucker rod of various outer diameter.
The securing member of sucker rod slips is bolt, and the other end of the first slips 1 and the second slips 2 offers the installing hole of the bolt that spins, Fast Installation and dismounting, convenient operation respectively.
The card tooth of sucker rod slips is provided with carburized layer, and card tooth is through high-temperature carburizing PROCESS FOR TREATMENT, and hardness is high, prevents from skidding in use.
The profile of sucker rod slips is designed to the cylinder type that external diameter can be used supporting with hydraulic tongs, can doubling folding, centre is designed with the two panels card tooth corresponding with sucker rod external diameter, first sucker rod slips is anchored on sucker rod body when upper button or shackle, after lock bolt locking, re-use hydraulic tongs fastening sucker rod slips body, equal to increase sucker rod external diameter, create leverage again simultaneously, so just can free and relaxed upper button and shackle.
The above is only preferred embodiment of the present utility model, is not limited to the utility model, under the prerequisite of answering, can also make some improvement and modification, and these improve and modification also should be considered as protection domain of the present utility model.When pointing out, for those skilled in the art, this practical technique principle is not being departed from.
