Abstract
The utility model relates to a self-adapting hoisting cable oil scraper which is composed of an oil hydraulic cylinder, a connecting rod, an oil scraper packing box and a packing; the packing is arranged in the oil scraper packing box, the connecting rod is transversely arranged above the packing box, a compression head in the middle part of the connecting rod is inserted in the packing box and tightly jack up the packing; the two oil hydraulic cylinders are symmetrically arranged at two sides of the packing box, the upper ends of the two oil hydraulic cylinders are respectively and fixedly connected with the two ends of the connecting rod by a bolt and nut, and the lower ends thereof are fixedly arranged on the oil well blowout preventer. The oil scraper has reasonable design and reliable working, and can replace traditional manpower machine tightening operation, the self-adapting compression of the oil scraper packing of the hoisting cable is realized by the connecting rod pulled by the oil hydraulic cylinder, thus being convenient for replacing the packing which can not be used continuously owning to excessive wear, greatly reducing the labor intensity of oil scooping workers and ensuring the safety and environmental protection in the oil scooping operating process.
Description
Technical field:
The utility model relates to a kind of wellhead assembly that oil field low pressure aclosed well oil salvage operation is used that is used for.
Background technology:
Along with the reduction of the prolongation of oil field development time and oil well formation pressure, production capacity, need to adopt well that oil salvage operation produces time more and more, the workload of oil salvage operation day by day increases.In the oil salvage operation process, the crude oil of from oil well, taking out of for fear of the wire rope ground of being scattered, pollute the well site, need to use the wire rope oil wiper, yet, when using existing wire rope oil wiper, after the rubber disc velamen steel rope abrasion in the wire rope oil wiper arrives to a certain degree, sealing performance lost efficacy, if further do not compress packing, the wire rope oil wiper can not play knife-type oil stripping action well, and the crude oil that wire rope is taken out of is with the severe contamination well site and influence carrying out smoothly of oil well oil salvage operation.
The utility model content:
Thereby the purpose of this utility model be to provide a kind of packing adaptive ability strong, can keep the frizing self-adapting type wire rope oil wiper that carries out guaranteeing oil salvage operation process safety and environmental protection working properly.
Above-mentioned purpose of the present utility model is to realize like this.This kind wire rope oil wiper is made up of hydraulic cylinder, connecting rod, oil wiper packing box, packing.In the oil wiper packing box packing is housed, the packing box top laterally is provided with connecting rod, and the hold-down head at connecting rod middle part inserts in the packing box, and packing is held out against; The packing box both sides are provided with two hydraulic cylinders relatively symmetrically, and two hydraulic cylinder upper ends are connected to a fixed with bolt and nut and connecting rod two ends respectively, and the lower end is installed and is fastened on the oil well preventer.During oil salvage operation, this device is installed in the oil well preventer top of bailing well well head, adopt double hydraulic cylinder to drive and replace traditional method that manually links closely, give the interior packing of wire rope oil wiper packing box with constant thrust, thereby guarantee that oil wiper frizing effect stability is reliable.Dredging vehicle is before work, at first steel wire penetrating wire rope oil wiper is linked to each other with barrel oil pump and weighted lever with the oil well preventer, under the derrick traction, weighted lever and barrel oil pump are put into well head then, at last well head linkage and well head big four flange are fixed.Simultaneously, hydraulic cylinder and connecting rod are installed, and, are made oil wiper packing top bear constant thrust to the hydraulic oil of hydraulic cylinder input constant pressure.The connecting rod two ends link to each other with hydraulic cylinder, and there is a circular ring type hold-down head centre, and connecting rod is down moved by Driven by Hydraulic Cylinder, but are subjected to the constraint of packing in the wire rope oil wiper, and the two is in the state of relative equilibrium.When packing increases because of the gap between wearing and tearing and the wire rope, thereby reduce gap between itself and the wire rope, realize self adaptation adjustment the packing wearing and tearing in the compression of constant thrust lower wall velamen.
The utility model is reasonable in design, reliable operation, utilize it can realize driving the traditional artificial tight machine operation of replacement with the biliquid cylinder, realize the self adaptation of wire rope Oil scraper packing is compressed by the connecting rod of hydraulic cylinder traction, can be connected fast between connecting rod and the hydraulic cylinder, be convenient to change the packing that can not continue to use, reduce greatly and drag for oily working strength of workers, guarantee the safety and the environmental protection of oil salvage operation process because of excessive wear.
Description of drawings:
Accompanying drawing is the structural representation under the utility model duty.Among the figure, label " 5 " is a wire rope, and label " 6 ", " 7 " are respectively oil well preventer and well head linkage.
The specific embodiment:
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.As shown in the figure, the utility model is made up of hydraulic cylinder 1, connecting rod 2, oil wiper packing box 3, packing 4.Its structural relation is as follows: 3 are equipped with packing 4 in the oil wiper packing box, and packing box 3 tops laterally are provided with connecting rod 2, and the hold-down head at connecting rod 2 middle parts inserts in the packing box 3, and packing 4 is held out against; Packing box 3 both sides are provided with 1, two hydraulic cylinder 1 upper end of two hydraulic cylinders relatively symmetrically and are connected with connecting rod 2 two ends with bolt and nut respectively and fix, and the lower end is installed and is fastened on the oil well preventer 6.Wherein, about two hydraulic cylinder 1 structures, specification identical, be symmetricly set on oil wiper packing box 3 both sides, hydraulic cylinder 1 is made up of cylinder body, connecting rod, piston, and rated operating pressure is 5MPa, adopts the rod chamber oil-feed, rodless cavity is fuel-displaced, and piston is in retracted state always during work.Connecting rod 2 is the body of rod of a long 1M, and its middle part is provided with the hold-down head that an annular protrudes downwards.
