Description
Technical field
The utility model relates to pipe lining layer technical field, especially a kind of rolling wheel for size reducing machine.
Background technique
In order to improve the technology that the service life technical staff of pipeline has invented the lined duct inside steel pipe, make steel
Inner wall of the pipe is covered by anti-corrosion, wear-resisting plastic tube, and liquid does not contact steel pipe, and steel pipe is reduced by directly etching and mill
Damage, to improve service life.In order to reach good liner purpose, need liner pipe outside diameter when producing internal lining pipe
Several millimeters are increased, fits closely liner pipe outer wall with former inner wall of the pipe, benefit brought in this way is liner tube wall
It will not cause premature fatigue rupture because of the variation repeatedly of Fluid pressure.But also make troubles to pipe lining construction, mistake
Big liner pipe outside diameter is not easy lining and is attached in former pipeline.It is wide in order to reduce lining processing difficulty in current lining processing
The general method for taking compression internal lining pipe, i.e., at the scene temporarily being compressed internal lining pipe using equipment makes outside diameter become smaller, then benefit
Internal lining pipe is interted into former pipeline with equipment, by heating or so that internal lining pipe is restored to original size in the way of time etc..
The compression liner tube apparatus is referred to as size reducing machine in industry, there are two types of modes for size reducing machine undergauge internal lining pipe at present, and one is contractings
Diameter covers mode, i.e., the installation band heating device undergauge sleeve in equipment, internal lining pipe be heated during by the sleeve and
Reduce outer diameter, then interts and enter in steel conduit, the undergauge mode is simple, and equipment volume is small and exquisite, and shortcoming is internal lining pipe
Heating slowly, serves as a contrast sometimes and restores then reduction of area diameter and be not over into partially having begun, and internal lining pipe and sleeve are sliding contacts,
Interspersed power is big, and internal lining pipe linear deformation is big, virtually increases the difficulty of construction of bushing pipe.Another kind is exactly to utilize rolling wheel compression
The method of internal lining pipe, that is, the rolling wheel undergauge that the utility model is previously mentioned.The undergauge mode equipment is more complicated, first will be same
The rolling wheel rim of one specification is together in series at a circular combination, then by the rolling wheel circular combination of several groups of different sizes, then
Concatenated combination is fixed together.Usual size reducing machine is divided into actively and passively, and active size reducing machine can pull internal lining pipe, and
Passive size reducing machine can only separately lean on other equipment to draw.The advantages of in the way of rolling wheel undergauge is internal lining pipe and rolling wheel is to roll
Contact, therefore interspersed power is smaller, and internal lining pipe linear deformation is small, and interspersed speed is fast etc..The disadvantage is that equipment is more complicated, every group of rolling
Pinch roller is at least two sets, and preferably at most eight, nine sets of (different according to liner caliber) every size reducing machines are exactly minimum eight sets of rolling wheels.Separately
Outside, petroleum pipeline specification is more complicated in the liner of oil field individual well production pipeline, usually from 114 millimeters of (2 inch -3 of φ 63- φ
Inch half) between, since the size reducing machine rolling wheel of every kind of specification is only applicable in a kind of specification internal lining pipe, so whenever there is different liners
Pipe construction will replace size reducing machine rolling wheel, and to adapt to liner caliber, so many rolling wheel will frequently replace rolling wheel right and wrong
Normal wasting manpower and material resources and time.But this size reducing machine has than very fast in the speed of construction, compares internal lining pipe damage
The advantages that small, is still widely adopted at present.
Summary of the invention
The purpose of the utility model is to provide a kind of rolling wheels for size reducing machine, and existing size reducing machine equipment construction is overcome to deposit
The different pipelines of correspondence and need to repeat replacement rolling wheel the problem of, need not be replaced with individual works or less replacement rolling wheel is
Purpose, so as to play the purposes of a machine plurality of specifications.
The purpose of this utility model is realized by following technological means: two sides undergauge machine support supports mandrel both ends
And it is fixed, the first rolling wheel and the second rolling wheel are installed on two mandrels up and down, internal lining pipe is pressed under the first rolling wheel, the
One rolling wheel and the second rolling wheel exterior arc surface are tangent, and outer surface groove corresponds to each other, and are fixedly mounted in the first rolling wheel side
There is transmission gear, hydraulic motor is installed in the side of undergauge machine support, pinion gear is installed on hydraulic motor output shaft, it is small
Gear is meshed with the transmission gear that the first rolling wheel side is installed, and the first rolling wheel and the second rolling wheel are on mandrel with liquid
Pressure motor does opposite circular motion by the power that gear transmits, and bearing is equipped on mandrel, and bearing inner race is contacted with mandrel,
The first rolling of bearing outer ring support, bearing gland side boss are pressed against bearing outer ring side, screw hole and rolling on bearing gland
Connection.It is recessed that first rolling wheel and the second rolling wheel outer round surface are provided with semicircular arc of multiple and different specifications for compressing internal lining pipe
Slot；Every group of rolling wheel groove arc size is identical, and corresponds.
The utility model is the utility model has the advantages that reasonable in design practical, and construction need not carry large quantities of replacements simultaneously again every time
Rolling takes turns to scene, and without a large amount of installation tool is prepared at the construction field (site), a size reducing machine covers the various rule of individual well substantially
The pipeline of lattice, accelerates manufacturing schedule, has significant economic benefit and social benefit.
