Description
The utility model relates to a kind of irregular surface cleaning device, is meant industry casing adapter screw thread cleaning devices such as a kind of oil drilling, geological prospecting especially.
In oil drilling, drill string is one of equipment very important in the oil drilling, on the one hand by it drill bit is delivered to thousands of meters underground, and it also plays the conveying high-pressure slurry on the other hand, transmits the important function of energy and power to drill bit.Drill string connects a drilling rod by a drilling rod and couples together, and the sealing between the drilling rod is to be undertaken by the contact between the tool joint screw thread end face.Institute is intrinsic owing to petroleum drilling operation, is often adhering to cement block on the drilling rod screw thread end face, coarse sand granule, or even the particle of various adamant matter.During jointed rod,, in the jointed rod process, will cause the screw thread end face to scratch, thereby influence the sealing performance of drilling rod junction as not eliminating effectively.Severe patient can cause the drilling rod junction minimum slit or cut to occur.Under high-pressure fluid in drilling rod is done at this moment, high-pressure fluid will ooze out along micro chink.Because the pressure of fluid is high in the drilling process, in case there is fluid to ooze out phenomenon along micro chink, high-pressure fluid will pierce through or sting bad tool joint very soon, cause pump pressure to descend and the drilling tool damage, force the drill-well operation personnel to carry out round trip, change the drilling rod that has damaged, have a strong impact on drilling progress and operating efficiency.When more serious, high-pressure fluid will sting breaking of rod bar, and lower drilling string is dropped in the down-hole, cause serious down-hole accident, and its economic loss will be very huge.On each oil field, annual because the drilling rod screw thread is impaired, round trip that causes and down-hole accident are very frequent, are very serious sometimes.
Cleaning drilling tool screw thread is still grasped usefulness so far by hand, to satisfy the requirement of petroleum drilling operation in sum.But manual operations is taken a lot of work, effort, time-consuming, and efficient is very low.
It is a kind of easy to adjust, flexible that the purpose of this utility model is to provide, and can adapt to constantly that the cleaning objects surface configuration changes, and the drilling tool screw thread cleans special mechanism.It can remove drilling tool screw thread and screw thread end face attachment rapidly, up hill and dale.It replaces increasing substantially cleaning efficiency after the manual operations, guarantees cleaning quality simultaneously, thereby reaches the purpose of protection drilling tool screw thread.
The purpose of this utility model reaches by following measure:
A kind of drilling tool screw thread cleaning device is characterized in that: it is made up of cleaning head, travel(l)ing rest, sliding support and motor and coupled central rotating shaft.Cleaning head is made of a pair of cleaning brush and pivoted arm, and the tail end of two cleaning brush is hinged with pivoted arm respectively, is provided with spring at their hinged part; Travel(l)ing rest is made of motion bar and linking arm, and the central point of pivoted arm is fixedlyed connected with central rotating shaft, and central rotating shaft directly links to each other with motor shaft; The moving platform of joining of the mid point of linking arm and central rotating shaft, the two ends of linking arm are hinged with two motion bars are movable respectively, and the other end of two motion bars is hinged with the mid point of two cleaning brush is movable respectively again; Along central rotating shaft parallel mobile be sliding support, sliding support is made of with the operating grip that links to each other with supporting arm the supporting arm parallel with linking arm, two guide pegs being vertically fixed on the supporting arm two ends; Sliding support is by guide peg and the guide securement support sliding-contact that is fixed on the motor housing, and a block bearing is equipped with in sliding support and central rotating shaft contact position.
When machine operation, drive pivoted arm and make circular motion, make the cleaning brush that is hinged with pivoted arm when making circular motion, constantly regulate the radial position of cleaning brush.Along central axes move operation handle, make sliding support do upper and lower motion, to regulate the axial location of cleaning brush.By continuous adjusting axial, radial position, make motor machine drilling tool screw thread cleaning device adapt to cleaning objects rule or irregular surface alteration of form flexibly, easily.Thereby reach the purpose of this utility model.
The utility model is compared with background technology has following outstanding advantage:
1, the utility model structure platform reason, can adapt to flexibly, easily and be cleaned the thing surface configuration and change, can remove various attachments and rust staining on the drilling tool screw thread.The casing adapter screw thread that not only can be applicable to industries such as oil drilling, geological prospecting well cleans, with control by the unclean injury that causes the screw thread end face of screw thread end face, and the down-hole accident that causes.The rule or the irregular surface that can also be used for other field in addition clean.
2, the utility model is simple in structure, easily easily assembling of processing, and in light weight, behaviour is with convenient.
3, compare with artificial cleaning, scrub drilling tool screw thread efficient and quality and all be improved largely, be about more than 15 times of manual efficient, and reduce labor intensity.
Accompanying drawing 1 is a drilling tool screw thread cleaning device structural representation.
To tie the platform the drawings and specific embodiments below does to describe in further detail to the utility model:
As shown in Figure 1, the tail end of cleaning brush 1 is hinged with pivoted arm 2 respectively, is provided with spring 12 at their hinged part; The central point of pivoted arm 2 is fixedlyed connected with central rotating shaft 5, and central rotating shaft 5 directly links to each other with motor 7 motor shafts; The mid point of linking arm 4 and central rotating shaft 5 movingly, the two ends of linking arm 4 are hinged with two motion bars 3 are movable respectively, the other end of two motion bars 3 is hinged with the mid point of two cleaning brush 1 is movable respectively again; Along central rotating shaft 5 parallel mobile be sliding support, sliding support is made of with the operating grip 9 that links to each other with supporting arm 10 supporting arm 10 parallel with linking arm 4, two guide pegs 6 being vertically fixed on supporting arm 10 two ends; Sliding support is by guide peg 6 and guide securement support 8 sliding-contacts that are fixed on motor 7 shells, and a block bearing 11 is equipped with in sliding support and central rotating shaft 5 contact positions.
Oil drilling is put into two spaces between the cleaning brush with the drilling tool screw thread.When machine operation, drive pivoted arm and make circular motion, make the cleaning brush 1 that is hinged with pivoted arm when making circular motion, constantly regulate the radial position of cleaning brush 1 by moveable hinge company headquarters part.Operating personnel's operating grip 9 makes sliding support do upper and lower motion, to regulate the axial location of cleaning brush.By continuous adjusting axial, radial position, make motor machine drilling tool screw thread cleaning device adapt to the surface configuration that is cleaned workpiece flexibly, easily and change.
