The detecting vehicle is composed of a handcart, a plastic water storage tank, a detector holding card, a regulating mechanism, a Z-shaped bipass pipe joint, a lifting and lowering rope, a probe holding device, a matching supersonic detector and a probe. The detecting vehicle is used for detecting the metal plate, which overcomes the defect that the detector scans the plate surface by holding the probe with hands. The utility model adopts a suspended type universal head to realize the optimum adhesion of the lower end face of a water jacket and the surface of the metal plate. The user can realize the flaw detection operation simultaneously when the user pushes the handcart. The labour intensity is reduced, and the detection speed and the reliability are improved. The utility model is suitable for units and persons making the ultrasonic detection for the metal plate.

Description

Metal plate supersonic detecting vehicle

The utility model sheet metal UT (Ultrasonic Testing) car relates to technical field of nondestructive testing.

At present, with defectiveness whether in the ultrasonic listening sheet metal, normally the flaw detection personnel squat on tested sheet metal, make couplant with water, and hand hold transducer moves the limit scanning in the sheet metal top.When large tracts of land was surveyed, the flaw detection personnel were very easily tired, squatted the waist and leg ache of a specified duration, and are dizzy; Cold season, also easy freezing hand.This method is very unfavorable to flaw detection personnel's health, and owing to be manual operations, has or not scanning to arrive entirely memoriter, is very easy to omit.

The purpose of this utility model is to provide a kind of and can alleviates the flaw detection personnel labor intensity, and the reliability of increasing work efficiency and detecting reduces omission, the sheet metal UT (Ultrasonic Testing) car that sheet metal is carried out ultrasonic listening.

In order to achieve the above object, the utility model sheet metal UT (Ultrasonic Testing) car is by (1) trolley; (2) plastics water storage tank; (3) defectoscope clamping card and governor motion; (4) Z type bipass joint; (5) halliard; (6) probe clamping device; (7) hose is equipped with ultrasonic wave detector and immersion probe combines.Trolley is the metal pipe frame structure, divides into five steamboats, back row's three-wheel, and front-seat (is preceding near the probe clamping device) two taken turns.Z type bipass joint is fixed on the trolley underframe, and plastics water storage tank and body frame adopt separate type, and the time spent is placed on the body frame.The probe clamping device is installed in the body frame front end, is the suspension type Universal-head.Wherein pop one's head in and have two pilot holes, two screw holes on the clamping collar.The first-class branch of the rotation collar has four pilot holes and two screw holes.Have annular positioning groove on the water jacket.Three rotational freedoms and a lifting degree of freedom are arranged when realization makes probe detection within the specific limits, fit with the best that realizes water jacket lower surface and sheet metal face.Under any circumstance all keeping parallelism is consistent with the sheet metal face for the probe end face.The trolley handgrip adopts the piston rod form, and height can suitably be regulated, and is screwed in two oblique vertical rods.Two oblique vertical rods are fixed on the body frame.Tiltedly be provided with clamping card and the governor motion that hangs ultra-sonic defect detector in the vertical rod.The clamping card is two right-angle plane shapes, have stalk hook-type garden arc groove on the face of right-angle plane, the two ends of another face become garden tubulose and vertical with the face that has stalk hook-type garden arc groove, are through respectively on the two parallel garden bars, and two clamping cards can be horizontally slipped on two parallel garden bars.Wherein go up parallel garden bar and be fixed in the two oblique vertical rods, in following parallel garden bar is enclosed within on two support bars in the long hook-type hole.Two support bars are flat strip shaped, an end activity, an end and tiltedly vertical rod hinge joint.In long hook-type hole, slide and realize the adjusting of instrument end slope degree by being enclosed within last lower beam in the support bar, squat down when doing the hand hold transducer scanning, can see the display screen of instrument clearly when visiting the wounded.One end of traction rope links to each other with the probe clamping device, but when stopping visiting the pull-up clamping device of popping one's head in, can play water saving.Like this, when utilizing the enforcement of sheet metal ultrasonic inspection car that sheet metal is detected a flaw, both can alleviate flaw detection personnel's labour intensity, and improve inspection speed again, the reliability of detection has also obtained reinforcement, can reduce omission.Can carry out by relevant non-destructive testing standard method, use operation to meet ZBJ74003-88, JISG0801 and SEL072, the technical requirement of ASTMA435A578 etc.Further specify enforcement of the present utility model in conjunction with Figure of description.A kind of sheet metal UT (Ultrasonic Testing) car is made by metal material and engineering plastics, and is in light weight, and Stability Analysis of Structures is easy to use.When need carry out ultrasonic listening to sheet metal, at first choose probe (twin crystal or single-chip) by relevant detection method, appropriate the Instrument working state adjustment, the probe that will mix up is contained in the clamping collar then, utilizes the deadweight of clamping device and tested sheet metal to fit automatically.When adopting the water logging flaw detection, during with the gap method, plastic cistern can be added water, water outlet of water tank and probe water jacket are coupled together through Z type bipass joint by hose, water just flows in the probe water jacket naturally; As adopt local water seaoning, and then external water source flexible pipe directly can be connected with Z type bipass joint, flow into another flexible pipe by bipass water and enter the probe water jacket, so far, can implement the operation of detecting a flaw.Ratio and the direction route on request of go-cart on one side carries out scanning, Yi Bian observe the oscillography screen or open warning device supervision in the defectoscope, reaches the purpose of automatic monitor alarm.Can finish detection light, comfortable, efficiently to sheet metal.

Claims (2)

1, a kind of by (1) trolley, (2) plastics water storage tank, (3) defectoscope clamping card and governor motion, (4) Z type bipass joint, (5) halliard, (6) probe clamping device, (7) hose and the sheet metal UT (Ultrasonic Testing) car that is equipped with ultrasonic wave detector and pops one's head in and combine.It is characterized in that its vehicle frame adopts the pipe support structure, the probe clamping device is installed in the body frame front end, adopts the Universal-head structure, can make probe have three rotary freedoms, a lifting degree of freedom, and water supply connector remains near in the 90 degree scopes of vehicle frame.
