Abstract
The utility model discloses a drilling-tool flaw-detector-head suspension device, which comprises a base, a bracket and a transverse movement mechanism, wherein the transverse movement mechanism is composed of a small bracket, a bottom plate, a roller, pulleys, a balance weight block and a steel rope; the roller is arranged on the bottom of the bottom plate, the small bracket is welded on the bottom plate, the upper end of the small bracket is provided with the pulleys, the balance weight block is arranged on the steel rope between the two pulleys, the lower end of the steel rope is used for suspending the flaw detector head and a hook is arranged on the lower end of the bottom plate. The utility model has the advantages of simple structure and convenient operation, can effectively eliminate the influence on the detection accuracy from human factors, lightens labor strength and enhances work efficiency.
Description
Technical field the utility model relates to a kind of oil drilling tools flaw detection servicing unit, especially a kind of drilling rod petiolarea flaw detection head bracing or strutting arrangement.
Background technology is along with the continuous development of drilling technology and drilling technology, drilling speed, mechanical separator speed are improving constantly, requirement to the drilling rod quality is also more and more higher, especially there is the endoporus reducing in drilling rod petiolarea (thickening disappears) position, serious and the stressed complexity of drilling fluid erosion in the drilling process, be prone to situations such as fatigue and inwall heavy corrosion, after long-time the use, the potential safety hazard of existence becomes increasingly conspicuous.After the Yellow River drilling well pipe company introduced UT2000 ultrasonic wave petiolarea defectoscope, the artificial palm top of defectoscope head rest existed human factor to influence greatly, detect unstable, the inaccurate phenomenon of testing result in the testing process.Its weight is big simultaneously, and operation is inconvenience extremely, and each operation needs the staff from head being put on the 1 meter high drilling rod in ground on the ground, after flaw detection finishes, lift down from 1 meter height again and be put on the ground so reciprocal operation, also increase operator labour intensity, had a strong impact on operating efficiency.
The summary of the invention the purpose of this utility model is a kind of drilling tool defectoscope head suspension device of design, to solve in the flaw detection of drilling rod petiolarea since human factor to the influence of carrying out flaw detection and the problem that labor strength is big, production efficiency is low.The utility model drilling tool defectoscope head suspension device, it comprises base, support, transverse moving mechanism.Support is made of column and crossbeam, and guide rail is installed on crossbeam, lays transverse moving mechanism on guide rail; Transverse moving mechanism is made up of small rack, base plate, roller, pulley, balancing weight and wire rope, roller is installed in the bottom of base plate, and small rack is welded on base plate, in the small rack upper end pulley is installed, balancing weight is installed on the wire rope between two pulleys, and the wire rope two ends connect the flaw detection head.Bottom at the transverse moving mechanism base plate is equipped with hook.Base is square iron plate structure, has constant weight, with support and other part gravitational loads on carrying top.Use the utility model, can make the defectoscope head in testing process, eliminate artificial factor, guarantee to detect and stablize, also reduced operator labour intensity simultaneously, improved operating efficiency.The utility model is adapted to the suspension of Other Instruments equally, also in protection domain of the present utility model.
Description of drawings Fig. 1 is a structural representation of the present utility model.1-base, 2-support, 3-base plate, 4-hook, 5-roller, 6-small rack, 7-hang balance weight mechanism, 8-pulley, 9-balancing weight, 10-wire rope, the 11-head of detecting a flaw.
The specific embodiment is with reference to accompanying drawing 1, drilling tool defectoscope head suspension device, and it is made up of base, support, transverse moving mechanism, suspension balance weight mechanism etc.Base (1) is square iron plate structure, has constant weight, plays the stable support effect, with the whole gravitational loads in carrying top, and has anti-down effect.Support (2) is made of column and crossbeam, and header portion is double guide rail bracket structure, transverse moving mechanism is driven by roller (5) move freely at crossbeam upper edge guide rail.Horizontal mobile device is made up of small rack (6) and roller (5), base plate (3) etc., hook (4) is equipped with in its bottom, when can or having bad luck drilling rod when not working, hangs hook (4) flaw detection head (11), pulley (8) is equipped with in 2 small racks (6) upper end, form suspension balance weight mechanism (7) by pulley (8), balancing weight (9) and wire rope (10), wire rope (10) connects flaw detection head (11).The utility model is installed in the station place that carries out the flaw detection of drilling rod petiolarea, when carrying out the drilling rod flaw detection, the head of will detecting a flaw is taken from hook, with hand it is left behind, wire rope falls from pulley, carry on the balancing weight, make the flaw detection head drop on drilling rod petiolarea position, start drilling rod petiolarea fault detection system, hand steered flaw detection head requires to detect a flaw operation according to flaw detection, and after flaw detection finished, the head of will detecting a flaw hung on the hook, next root drilling rod is poured on the work station, repeat above-mentioned work, carry out drilling rod petiolarea flaw detection operation, because the effect of the suspension balance weight mechanism of this suspension type petiolarea flaw detection head bracing or strutting arrangement, the effect of moving the flaw detection head and setting upright by the flaw detection demand has been played in manually-operated, flaw detection head when work only make flaw detection roller (in probe is arranged) in the drilling rod operation of detecting a flaw under the effect of its deadweight, eliminated the influence of human factor (propose or press), guarantee to detect and stablize, also do not need reciprocal the popping one's head in of operator simultaneously in the operation from handling between ground and the drilling rod.
Claims (2)
1. drilling tool defectoscope head suspension device, it comprises base (1) and support (2), it is characterized in that support (2) is made of column and crossbeam, and guide rail is installed on crossbeam, lays transverse moving mechanism on guide rail; Transverse moving mechanism is made up of small rack (6), base plate (3), roller (5), pulley (8), balancing weight (9) and wire rope (10), roller (5) is installed in the bottom of base plate (3), small rack (6) is welded on base plate (3), in small rack (6) upper end pulley (8) is installed, balancing weight (9) is installed on the wire rope between two pulleys, and wire rope (10) two ends connect flaw detection head (11).
2. drilling tool defectoscope head suspension device according to claim 1 is characterized in that in the bottom of transverse moving mechanism base plate (3) hook (4) being installed.
