Abstract
The utility model relates to an inner steel brush of a centrifugal petroleum casing tube, which is composed of a steel brush body, steel brush heads, a motor, a trailer and a telescopic pull rod, wherein the steel brush body is in a circular ring shape and is fixed to a rotary shaft of the motor in a key connection mode. Jacks are distributed on the periphery of the steel brush body, and the steel brush heads are arranged in the jacks and are connected with the steel brush body with the aid of fixing pins. One end of the telescopic pull rod is connected with the motor in a screw thread mode and is connected with the trailer through pins. The utility model has the characteristics of convenient operation, no high-pressure water source or high-pressure air source, no quartz sand, small danger and low investment and is particularly suitable for field operations.
Description
The utility model relates to a kind of oil drilling internal surface of sleeve pipe cleaning means.
The oil anticorrosive casing pipe all will carry out cleaning treatment to inwall usually before using, coat anticorrosive coat then.Being used for the method that the oil drilling internal surface of sleeve pipe cleans at present, generally is to adopt the high pressure sandblast technology.Drive quartz sand with water under high pressure or high pressure gas, high velocity jet is cleaned rust staining and dirt on the inwall to the steel internal surface of sleeve pipe.But sandblast needs big scale fixed equipments and factory building, and high-pressure water or high-pressure air source be arranged, and a large amount of quartz sand with certain particle size be arranged, and investment is big, the cost height, and certain danger is arranged, generally be suitable for cleaning in the more large batch of sleeve pipe.
The purpose of this utility model is to overcome the limitation of above-mentioned prior art, uses steel brush and designed in a kind of centrifugal petroleum casing pipe.This steel brush makes brush can make inside and outside stretching motion according to the centrifugal principle that rotatablely moves, and guarantees that the wire brush hair root according to needs contact sleeve inside pipe wall, cleans.This steel brush is easy to carry, both can be in factory building the cannula cleaning inwall, be more suitable for cleaning the petroleum casing pipe inwall in open-air situ of drilling well.
The purpose of this utility model is achieved in that in the centrifugal petroleum casing pipe and is made of brush body, brush, motor, trailer, Telescopic handle with steel brush; The steel brush body becomes circular, and be fixed on the key ways of connecting on the turning cylinder of motor, the brush body periphery is distributed with jack, pack into jack and connect by fixing pin and brush body of brush, one end of Telescopic handle and motor are bound up with trailer again by pin simultaneously with spiral marking connection.This covering device is put into sleeve pipe, and the motor rotation drives steel brush and rotates, and can carry out the operation of cleaning sleeve inside pipe wall.
The utility model has the advantages that: equipment is simple, and easy disassembling is easy and simple to handle, does not need high-pressure water or high-pressure air source and a large amount of quartz sand, and is dangerous little, invests lowly, particularly is applicable to the field condition operation.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described:
The utility model is made of steel brush head 1, steel brush body 2, motor 4, trailer 5, Telescopic handle 7 and pin, steel brush body 2 is circular, and be fixed on the key ways of connecting on the turning cylinder of motor 4, the brush body periphery is distributed with jack, be provided with the steel brush head in the jack, and by fixing pin 3 and steel brush sports association knot, an end of Telescopic handle 7 and motor 4 spiral marking connections are bound up by pin 6 and trailer 5 simultaneously.
During use, the steel brush head 1 that will have the steel wire bristle inserts in the jack of ring-type steel brush body 2 peripheries, and connects each other with pin 3, can make the turnover stretching motion of certain amplitude for making brush in brush body, with the pin socket design rectangularity groove at jack edge; The rotating shaft of motor 4 is fixed together with key connected mode and brush body 2, and an end of Telescopic handle 7 and motor 4 connect via pin 6 and trailer 5 simultaneously to be threaded, and power line 8 is by passing in the pull bar.Pull bar 7 is nested together by inside and outside bar, by adjustment screw 9, can make inside and outside bar draw back and fix, and guarantees that steel brush has enough displacements in sleeve pipe.Drive trailer when motor rotates and rotate, the angle design between horizontal two wheels of trailer becomes 90 degree, and caster can up-down adjustment, and fixing by screw 10.
