Face hugs sucker rod wall, with the lifting of rod string, the oily wax of adhesion on sucker rod wall is scraped.Keep off factice ring 10 He simultaneously
The inner hole surface of air bag 15 is also close to sucker rod, cleans sucker rod further.The thin oil scraping is from the through hole of blowout prevention box assembly 7 of shunting in a well
Place falls in well；Viscous crude and wax then passes through housing 2, be arranged at oil wiper outer sleeve 21 bottom steel loop 3, paraffin scraper overcoat 5
On barrel fluting a, b, c, d at squeezed fall to being collected on oil drain pan 13, at the perforate e of oil drain pan 13, reach cleaning and take out
Beam hanger, the purpose of environmental protection operation.
Paraffin cutting steel wire 6 can be removed the obstinate oil wax of attachment on sucker rod in time, sucker rod after paraffin cutting device assembly,
Remain in the part crude oil on sucker rod, then the oil pumping rod aperture 26 through gear factice ring 10 middle part setting, frizing gum cover 4 and inflation
The process of air bag 15, thus reaching the effect of frizing paraffin cutting, oil-scraping device and wax scraping apparatus are not due to having and upper cover body 1 or air bag
Room lower cover is fixed, and the oil-scraping device of barrel-type casing 2 and composition pumping rod wax scraping oil scraping mechanism assembly and paraffin scraping mechanism are between the two
Horizontal direction is set with certain glade plane space f, can radial misalignments move wherein, therefore processes sucker rod skew at any time and makes
The eccentric wear becoming, scrapes unnet situation.Novel sucker rod frizing blowout hookup can play generation and the frizing of Prevention of blowout accident
The environmental requirement of paraffin cutting.
Constitute frizing gum cover 4(in gum cover oil scraping mechanism as shown in Figure 1, 2, 3) longitudinal embedded spring steel plate 22 in anchor ring,
Its diametric(al) has cross (or rice word) otch 23, to enable its diameter to reduce and to expand, is easy to by rod string
On the box cupling that is relatively large in diameter and centralizer 32 recover frizing major dimension (oil pumping shank diameter)；Paraffin cutting steel wire 6 is by axial screw
, near the position of centre bore, its scraping power (is scraped to be fixed on gasket ring 12 under gasket ring 11 and paraffin cutting fixation with steel wire in paraffin cutting fixation with steel wire
The Circularhole diameter being formed at wax steel wire 6 interlacing contact) by being connected to upper and lower fixing gasket ring 11, single circle spring on 12 borders
Constitute, the frizing paraffin cutting steel wire 6 that between upper and lower gasket ring, the border six roots of sensation screws forms and the endoporus 27 of sucker rod can be passed through to be coaxially located at
In circle spring 27, when the box cupling being relatively large in diameter on rod string and centralizer pass through sucker rod endoporus 27, spring can be driven
Compression makes Distance Shortened between upper and lower gasket ring, makes the endoporus 27 that frizing paraffin cutting steel wire 6 is formed thicker, on rod string simultaneously
The box cupling being relatively large in diameter and centralizer pass through, and recover frizing after the box cupling being relatively large in diameter on rod string and centralizer
Major dimension (oil pumping shank diameter).
In constituting the multi-functional beam hanger frizing de-waxing apparatus involved by present patent application,
Constitute the pumping rod wax scraping oil scraping mechanism assembly of this device, both can be as shown in Figure 1 by being arranged in housing
Steel wire paraffin cutting oil scraping mechanism, gear factice ring, gum cover oil scraping mechanism and air bag oil scraping mechanism jointly fold sieve and constitute or steel
Silk paraffin cutting oil scraping mechanism and gum cover oil scraping mechanism and be arranged at gear factice ring between the two and constitute, or by being arranged in housing
Steel wire paraffin cutting oil scraping mechanism and gum cover oil scraping mechanism constitute；The technique effect to sucker rod frizing wax removing all can be reached；
Constitute the structure of this device, both can be as shown in Figure 1 by the barrel-type casing being provided with upper press cover be arranged at
Pumping rod wax scraping oil scraping mechanism assembly in this barrel-type casing and the blowout prevention case structure composition being fixed on this barrel-type casing bottom,
During use, direct blowout prevention case structure is installed on well mouth of oil well, and this device then has the function of preventing blowout, well when even playing bar
Inside have oil gas overflow when can rotate rapidly shut-in well blowout prevention box assembly 7 both sides leading screw 29 closing well it is ensured that well control safety；Can also
It is to be made up of the barrel-type casing being provided with upper press cover and the pumping rod wax scraping oil scraping mechanism assembly being arranged in this barrel-type casing, make
Used time directly barrel-type casing is fixed on well mouth of oil well, typically blowout will not occur in the case that other measures are controlled,
Therefore do not assemble the complexity that well blowout preventing mechanism can reduce its structure；
Constitute the frizing paraffin cutting steel wire 6 of above-mentioned steel wire paraffin cutting oil scraping mechanism, upper and lower gasket ring can be disposed on according to design
Between border fix the six roots of sensation, three screw 180 degree or 90 degree, even 270 degree frizing paraffin cutting steel wire 6, its objective is this rotation
Stubborn frizing paraffin cutting steel wire forms the endoporus 27 that can pass through sucker rod；When steel wire radical less and the angle that screws less to taking out
The resistance that the rising of beam hanger is formed is less, is conducive to the lifting of sucker rod；Otherwise effect or more preferable is drawn to the large-fruited hodgsonia of scraping of sucker rod,
But its resistance can increase；
Constitute above-mentioned steel wire paraffin cutting oil scraping mechanism spring assembly not only can when as above by single circle spring
Constitute or by be fixed on upper and lower fixing gasket ring 11, be cased with respectively on 12 borders two of spring 8, carry out be three or
Four spring guides 9 are constituted；Pass through the stretching to upper and lower fixing gasket ring 11,12 for this spring assembly, the frizing realizing screwing is scraped
Wax steel wire forms the diameter change of the endoporus 27 that can pass through sucker rod, is beneficial to the box cupling being relatively large in diameter on rod string
And the passing through of centralizer；
In order to prevent upper and lower fixing gasket ring 11,12 from shifting when sliding up and down in the presence of spring assembly, cause many
The angle that screws of the individual frizing paraffin cutting steel wire 6 screwing changes, and sets up in above-mentioned paraffin scraper cylindrical jacket 5 inwall axle
There is the sliding tray 28 of upper and lower fixing gasket ring 11,12；
For the ease of dismounting operation after pull-out for the sucker rod, the oil pumping rod aperture of upper press cover 1 is provided with and is easy to operation
Platform ring 25；
The gear factice ring 10 of setting between steel wire paraffin cutting oil scraping mechanism and gum cover oil scraping mechanism, its structure both can be as figure
Middle part shown in 1 be have two (or multiple) platform rings 30,31, centre be oil pumping rod aperture 26 structure, this oil pumping rod aperture
Oily wax on sucker rod can be wiped off or is not had with the sucker rod pore structure being relatively large in diameter of frizing wax function.
