Abstract
The utility model relates to an automatic scale-removing device for the polished rod of an oil pumping unit, composed of a scale-removing tool apron, a scale-removing tool, a baffle and two fastening bolts, wherein one side of the scale-removing tool apron is chordwise tangential plane structure, a clamping groove is disposed on the scale-removing tool apron, and the scale-removing tool is located in the clamping groove; the baffle is installed on the chordwise tangential plane part of the scale-removing tool apron via a thread connection piece; and the two fastening bolts are installed on the side parts of the baffle and the scale-removing tool apron via threads respectively. The device has a function of automatically removing scales on the surface of the polished rod, so that the polished rod is always in a good normal working state, thereby efficiently avoiding the problem of environmental pollution in a well site caused by a loosened sealing of packing and a leakage of oil due to the scaling of the oil pumping polished rod; as a result, the loss of oil a well mouth is reduced, the occurrence of pollution is prevented, and the service life of the oil pumping polished rod can be prolonged. Using the device, the normal operation of the oil pumping unit can be reliably ensured, the production efficiency can be increased, and the labour intensity can be lightened; moreover, the automatic scale-removing device for the polished rod of an oil pumping unit is convenient to install and use.
Description
Technical field
The utility model belongs to pumping unit attachment technique field, oil field, is the automatic snaking device of a kind of oil-extractor polish-rod.
Background technology
In the oil exploitation in oil field, when oil pumper when carrying out swabbing operation, oil pumping polish rod is to pump at the well head place; Owing to contain water, the grains of sand, paraffin in the crude oil of pumping from oil well and contain various impurity such as glue material; Under the effect of heating-up temperature, these crude oil that contain various impurity stick on the surface of oil pumping polish rod, are easy to generate fouling; Cause oil pumping polish rod rough; And the polished rod after the fouling causes wearing and tearing to the well head sealed packing, causes packing to lose sealing function, causes the pollution in leakage and well site.The method of usually oil pumping polish rod being carried out scale removal is; Shut down the back utilize artificial with knife scrape, file is frustrated and sand paper mode such as beat is removed, but after each the removing, oil pumping polish rod work new dirt of knot again after 3～5 days; Scale removal so repeatedly; Not only time-consuming, effort, labour intensity is big, and directly influences the timeliness of oil well production.
The utility model content
The purpose of the utility model provides a kind of under non-stop-machine situation, can realize the automatic removing of polished rod fouling, makes polished rod be in good normal operating conditions all the time, guarantees the automatic snaking device of oil-extractor polish-rod of the normal operation of oil pumper.
The technical scheme that the purpose of realization the utility model is taked is: this device is made up of snaking tool rest, snaking cutter, baffle plate and 2 fastening bolts; Wherein, One side of snaking tool rest is the flat-cut plane structure, and the snaking tool rest is provided with buckling groove, and the snaking cutter spacing is in buckling groove; Baffle plate is installed in the position, flat-cut plane of snaking tool rest through threaded connector, and 2 fastening bolts are contained in the sidepiece of baffle plate and snaking tool rest respectively through being threaded.
Said snaking cutter is by two cutter hub involutory compositions, the semicircle cambered surface of the upper inner of cutter hub for matching with the oil pumping polish rod external diameter, and the bottom of cutter hub is provided with the fixed block that cooperates with said fastening bolt.
The top of said cutter hub is provided with flange.
The bottom of said fixed block is provided with flange.
Said fixed block is provided with the locating hole that cooperates with fastening bolt.
The automatic snaking device of oil-extractor polish-rod according to such scheme is processed has the function of automatic removing oil pumping polish rod fouling, can make polished rod be in good normal operating conditions all the time.Thereby the well site environmental pollution problem of effectively having avoided fouling because of oil pumping polish rod that packing_seal is not sternly caused after the leakage has reduced the leakage of well head thus, has prevented the generation of polluting, and can prolong the application life of oil pumping polish rod.Use this device, can guarantee the normal operation of oil pumper reliably, and can enhance productivity, reduce labor intensity, and easy to install.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of snaking cutter among Fig. 1.
The specific embodiment
Referring to Fig. 1, Fig. 2, the automatic snaking device of the oil-extractor polish-rod of the utility model is made up of snaking tool rest 1, snaking cutter 2a, 2b, baffle plate 5 and 2 fastening bolts 6; Wherein, One side of snaking tool rest 1 is the flat-cut plane structure, and snaking tool rest 1 is provided with buckling groove 4, and snaking cutter 2a, 2b are positioned at buckling groove 4; Baffle plate 5 is installed in the position, flat-cut plane of snaking tool rest 1 through threaded connector, is used for the locking of buckling groove 4.One of them fastening bolt 6 is through being threaded in the sidepiece of baffle plate 5, and another fastening bolt (not shown) is contained in the other side of snaking tool rest 1, and two fastening bolts are mainly used in the radially adjustment in snaking cutter 2a, 2b axle center and compress.Snaking cutter 2a, 2b form by the cutter hub of two symmetries is involutory; The semicircle cambered surface 2-1 of the upper inner of cutter hub for matching with oil pumping polish rod 3 external diameters, the interior circle that cutter hub two halves arc surface is combined to form and the junction of following section are configured for striking off the blade of grease on the oil pumping polish rod 3.The bottom of cutter hub is provided with the fixed block 2-5 that cooperates with fastening bolt 6, and the top of cutter hub is provided with flange 2-4, is used for load at snaking tool rest 1.In order to prevent the axial float of cutter hub, be provided with flange 2-3 in the bottom of fixed block 2-5, and on fixed block 2-5, be provided with the locating hole 2-2 that cooperates with fastening bolt 6.This installs in use, and the cutter hub with snaking cutter 2a is installed in through fastening bolt in the buckling groove 4 of snaking tool rest 1 earlier, then snaking tool rest 1 is seated on the packing box 8; And make in the oil pumping polish rod 3 corresponding reeve buckling grooves 4; Contact with the cutter hub arc surface of snaking cutter 2a, again the cutter hub of snaking cutter 2b is packed in the buckling groove 4, and load onto baffle plate 5 after involutory with the cutter hub of snaking cutter 2a; Through regulating the fastening bolt 6 of both sides; Make the interior circle of snaking cutter 2a, 2b cutter hub concentric, and two cutter hubs are closely fastened, match with oil pumping polish rod 3 diameters with the oil pipe of production wellhead.Back and forth in service at oil pumping polish rod 3 can scrape the grease on the polished rod 3.And be the snaking that under non-stop-machine situation, carries out oil pumping polish rod, can guarantee the cleaning on oil pumping polish rod 3 surfaces thus all the time, reduce the running resistance of oil pumping polish rod 3, practice thrift the power consumption of oil pumper, can also prolong the application life of oil pumping polish rod 3 greatly.
