The specific embodiment
For making goal of the invention of the present utility model, technological means and technique effect have more complete and clearly disclosing, hereby in lower detailed description, and see also accompanying drawing and element numbers.
See also illustrated in figures 1 and 2, the utility model provides a kind of polished rod of pumping well clamper, formed by two clamping limbs, 100 horizontal make-ups, wherein each clamping limb 100 comprises: strip main body 11, one side of main body 11 is the binding faces 110 that fit tightly with another clamping limb 100, be spaced along the longitudinal at binding face 110 and be provided with the parallel hole slot 112 in three roads, main body 11 laterally offers the bolt hole 113 of perforation on the edge, position of the three road hole slots 112 that stagger, the outside one in main body 11 both sides is extended ear 12, offers combined hole 121 in the ear 12; See also Fig. 3 and Fig. 4, described two clamping limbs 100 are behind binding face 110 make-ups, wherein three road hole slots 112 of a clamping limb 100 align one by one with three road hole slots 112 of another clamping limb 100 respectively, and form in order to the hair pigtail hole 21 that wears two hair pigtails 8 and the polished rod hole 22 that wears a polished rod 9 between two hair pigtails 8, wherein hair pigtail hole 21 has the gap with the hair pigtail 8 that is arranged in wherein, to provide mao pigtail axial being slidingly matched; Bolt hole 113 axial alignment of the described bolt hole 113 of a clamping limb 100 and another clamping limb 100 wherein simultaneously, and form the through hole that cooperates and two clamping limbs 100 are clamped for bolt 7 nut (not shown); Combined hole 121 axial alignment of the described combined hole 121 of a clamping limb 100 and another clamping limb 100 wherein simultaneously, and form the through hole that cooperates and two clamping limbs 100 are clamped for bolt 7 nut (not shown).It should be noted that although the utility model is defined as combined hole at this conjunction with ear and wears bolt, variation roughly the same, the cooperation etc. such as groove and projection also should be considered as being encompassed under the overall inventive concept of the utility model.
Please consult again Fig. 1 to Fig. 3, the main body 11 of described each clamping limb 100 offers two described bolts hole 113 parallel to each other at the in twos interval of described three road hole slots 112, described two clamping limbs 100 are behind binding face 110 make-ups, each bolt hole 113 is axial alignment and can make the respectively parallel main body 11 that wears each clamping limb 100 of two bolts 7 respectively, and by nut with 100 lockings of two parts main body.But the utility model is not as limit, and laterally sealed bolt and nut also can differ from two groups.
Please consult again Fig. 1 to Fig. 3, one side of the main body 11 of described each clamping limb 100 is extended described ear 12 along the outside one of the first half of main body 100, and the opposite side of main body 11 extends described ear 12 along the outside one of the latter half of main body 11, and each ear 12 longitudinally offers described combined hole 121; Described two clamping limbs 100 are behind binding face 110 make-ups, wherein the ear 12 of a clamping limb 100 vertically is stacked with the ear 12 of another clamping limb 100, and the vertically alignment and two bolts 7 are worn respectively be positioned at each ears 12 of described main body 11 both sides of the axis of its combined hole 121, and by nut with 100 lockings of two clamping limbs.Just finish thus two clamping limbs 100 of the utility model at horizontal and vertical bidirectional locking, provide higher polished rod grip strength with this.
Further, the shape of described two clamping limbs 100 is identical, and two clamping limbs 100 align respectively described hole slot 112, combined hole 121 and bolt hole 113 on each clamping limb 100 by being inverted mutually make-up.But the utility model is not as limit, and the shape of two clamping limbs 100 can be incomplete same, and only provide the correspondence of each hole, hole slot also can.
Further, the aperture in described polished rod hole 22 is more than or equal to the diameter that is arranged in polished rod 9 wherein, and this aperture is less than the external diameter of the polished rod box cupling 90 that is positioned at the polished rod top.In the situation that aperture, polished rod hole equals the polished rod diameter, the polished rod clamper produces polished rod and grips, and polished rod does not produce axial float in the polished rod clamper; Preferably, in the situation that aperture, polished rod hole is greater than the polished rod diameter, polished rod and polished rod hole are slidingly matched, and when disconnected bar occured, the disconnected bar of epimere glided along the polished rod hole, until the bottom surface of polished rod box cupling fastens on the polished rod clamper, and form clamping to polished rod.
In practical engineering application, the pitch-row of the combined hole of offering in the ear of main body both sides is 330mm, and the pitch-row of two bolts hole is 50mm on the main body, and these holes all are unthreaded holes, do not have internal thread.What bolt used is the plain bolt of M16.The pitch-row in two hair pigtail holes is 250mm, and middle polished rod hole is Φ 28.
Operating principle of the present utility model is as follows:
Bolt and nut be connected each combined hole and each bolt hole play the effect that connects two clamping limbs; Two maos of pigtail holes are to cooperate with the hair pigtail (rope plait) of pumping unit horsehead, play the effect of polished rod righting on the hair pigtail; The polished rod hole cooperates with polished rod, and when polished rod of pumping well was disconnected, disconnected bar top will be fixed on the rope plait, can not fly ground like this, played the effect of protection operation site safety.Polished rod clamper of the present utility model is installed between load-bearing clamp and the polished rod box cupling.
The utility model is through repetition test, and behind the real polished rod break bar of obituary, the disconnected bar in top can not drop again, has stopped the potential safety hazard of production scene.
Above for only being the schematic part embodiment of the utility model; be not to limit scope of the present utility model; any those skilled in the art; the equivalent variations of having done under the prerequisite that does not break away from design of the present utility model and principle and modification all should be included within this patent protection domain.
