Abstract
A skidproof vice for replacing polished rod stuffing of a sucker rod belongs to the class of sealing tools for sucker rods. A sucker rod continuously moves up and down in a pumping unit so that stuffing in a stuffing sealer is often abraded, and thus, the stuffing often needs to be replaced continuously. The prior art mainly adopts a binding method with iron wires or coir ropes to hang a stuffing press cover on the sucker rod so that when the stuffing is replaced, pounding and falling accidents frequently occur; in addition, because replacement takes time, the production of an oil well can be delayed. For the purpose, the utility model adopts a vice jaw device, a main body of which is provided with a tiger mouth. When the utility model is used, the stuffing press cover is sandwiched in the utility model and is fixed to the sucker rod, and then, the stuffing in a stuffing box can be replaced quickly and safely so that the down time of the pumping unit is reduced. The vice can be widely used for the replacement of polished rod sealing stuffing of a pumping unit well.
Description
Technical field:
The utility model relates to a kind of anti-skidding pincers that are used to change the sucker rod Polish rod packing, belongs to sucker rod sealing tool class.
Background technology:
Oil pumper is in operation; since the sucker rod polished rod in oil well constantly with on the sucker rod; following motion; packing seepage phenomenon takes place through regular meeting; for this reason; at pithead position special-purpose packing box is installed and is used for leakproof; because packing is frayed in the box; need to change, traditional replacing method be with iron wire or coir rope with the packing box tighten after, be fixed on above the polished rod; and then the packing in the box changed; can often occur like this because of the loosening box body of iron wire injures people's accident by a crashing object, in addition, because operation inconvenience; the replacing time is long also can to influence oil well output, and the utility model adopts specific purpose tool to change packing to overcome above-mentioned shortcoming for this reason.
The utility model content:
The purpose of this utility model, be in order to overcome above-mentioned shortcoming, and a kind of anti-skidding pincers that are used to change the sucker rod Polish rod packing that provide, this instrument can be fixed to packing gland above the oil-extractor polish-rod, then change the sucker rod Polish rod packing, safe and efficient, can reduce the well workover time again, improve well oil output.
Working method of the present utility model is:
The utility model is that a tiger jaw is housed on body, is fixing two pincers handles by axis, at pincers there is a tailing axle big open top end position, is fixing a screw rod, and the other end is fixed on screw rod on the top of another pincers handle with nut.
Tiger position in the described jaw has the zigzag protruding canine teeth, and described body adopts 45CrMo steel material to be made.
The utility model compared with prior art has distinguishing feature.
Because the utility model adopts the jaw have tiger, during use, only need the packing lid is clamped in above the teeth in the tiger, be fastened to again on the polished rod by the screw rod above the far-end tailing axle promptly replaceable, packing in the box body.Convenient and safe especially, can save packing again and change the time, shorten the oil pumper off-time, increase oil well output.
Description of drawings:
Figure is the utility model structural representation.
Among the figure by 1, jaw, 2, axis, 3, pincers, 4, tailing axle, 5, screw rod, 6, body forms.
The specific embodiment:
The utility model is provided by following examples.
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure, jaw 1 is positioned at body 6 foremost position, it is fixed together 3 by axis 2 intersections by two pincers, be inlaid with the zigzag protruding canine teeth on the jaw, protruding canine teeth can improve the clamping degree of workpiece, prevent that workpiece from coming off, axis 2 is a fixator pins, two pincers are fixed together 3 by it, axis 2 and pincers between for being slidingly matched, tailing axle 4 is for being located at pincers an axle on 3 right tops, and with linking together surely, screw rod 5 other ends intert in the eyelet on the right top of lower clamp handle screw rod 5 one ends for this, and tighten up by nut, the effect of this screw rod is when jaw clamps the packing box gland on body 6, by screwing nut, the packing box gland at jaw tiger place can not split away off above polished rod.
