Description

Large-diameter pipe ultrasonic wave simulating test pieces bracket

Technical field

The utility model relates to Ultrasonic Nondestructive fields, and in particular to a kind of large-diameter pipe ultrasonic wave simulating test pieces branch Frame.

Background technique

Ultrasonic wave simulating test pieces are for the actual defects and the reference coupon that makes of weld seam in simulation workpiece welding, mainly Research, nondestructive testing personnel qualification for detection method are examined and evaluation, evaluation and validation instrument probe system detectability It is the important equipment in ultrasound examination with characterization processes etc..

Since the usual tube wall of large-diameter pipe is compared with thick, volume is big, quality weight, the weight of the unbearable simulating test pieces of common workbench Amount, and people completion is extremely difficult to the detection of large-diameter pipe simulating test pieces.Currently used detection method is following three kinds:

One, large-diameter pipe test block is placed directly on ground and is rolled, to complete the complete detection to test block weld seam.It is this For method when rolling test block, the weld reinforcement of middle part protrusion easily damages ground or floor tile, the machine oil used or other couplings by pressure Mixture is easy pollution ground.Test block will be fixed after rolling every time, prevent rolling in detection process to testing staff or Other articles cause to damage, very inconvenient.

Two, test block is stood on the ground, test block is motionless, and testing staff changes detection position to complete the inspection to test block weld seam It surveys.The end of test block and ground face contact in this method, machine oil or other couplants can also be flowed on bottom surface by gravity and be made At pollution.When standing up test block, weld seam terrain clearance is smaller, and testing staff can only squat down on the ground detection, large-diameter pipe test block detection Time long personnel are easy fatigue.Wanted when carrying out defect location using ruler side head read, sight is bad, and reading is difficult, And it squints ruler scale and is easy to produce error in reading, in turn result in defect location inaccuracy.

Three, it is passed through in the middle part of large-diameter pipe test block with steel pipe or fashioned iron, test block is then lifted away from ground, by steel pipe or fashioned iron two End is placed on firm bracket or in cement platform, and test block is motionless, and testing staff selects suitable position to detect.In this way Need to make respective holder or masonry cement platform, bracket is integrally larger, it is more to account for lab space, and do not have after bracket fixation Method is mobile, is unfavorable for the arrangement in laboratory.Due to test block be self-possessed it is larger, for a long time using it is easy bend the steel pipe that passes through or Fashioned iron generates security risk.This kind of method is also required to testing staff's change detection position, and the detection process used time is longer.

Summary of the invention

To solve the above-mentioned problems, the utility model discloses a kind of large-diameter pipe ultrasonic wave simulating test pieces bracket, can support Heavy weight simulating test pieces can also move integrally, and facilitate the detection and storage of large-diameter pipe ultrasonic test block.

Large-diameter pipe ultrasonic wave simulating test pieces bracket, including frame, the upper plane of the frame are symmetrically arranged with long slot hole, often A long slot hole respectively installs two adjustable support wheels in position, and multiple scroll wheels are arranged in the frame bottom surface；

The support wheel includes the bolt through long slot hole, and the bolt and the first U-shaped frame are cooperatively connected, the bolt Nut portion is located at plane on the bottom plate of the first U-shaped frame, and the first U-shaped frame is connect with the first pin shaft, first pin shaft with The first nut and the first gasket, the bolt position is arranged in the rotation connection of first idler wheel, the position that the bolt is located at frame or more In frame position below, the second nut is set；

The scroll wheel includes the third nut connecting with frame, and the third nut and stud are cooperatively connected, the spiral shell Column passes through the bottom plate of the second U-shaped frame and the 4th nut is cooperatively connected, and the second U-shaped frame is connect with the second pin shaft, and described second Pin shaft and the second idler wheel are rotatablely connected, and brake block is arranged on the second U-shaped frame.

Preferably, the frame is the weldment of channel steel or band steel or angle steel composition, framework upper supporting beam and lower part branch Auxiliary stand is set between support beam；

Preferably, the channel steel specification is 120mm × 50mm × 5mm, and the auxiliary stand is Φ 48mm × 6mm tubing；

Preferably, the second gasket is set between the nut and the first U-shaped frame；

Preferably, first idler wheel and the second idler wheel are deep groove ball bearing.

The utility model has the beneficial effects that

(1) by the cooperation of framework upper multiple groups support wheel, large-diameter pipe simulating test pieces can safely be placed, make test block from Ground is opened, the pollution of machine oil or other couplants to ground is avoided.And bracket itself is also a detection station, detection Personnel's nature standing state can carry out ultrasound examination to simulating test pieces, provide detecting state as snug as a bug in a rug.

(2) large-diameter pipe simulating test pieces are placed on bracket, the idler wheel of test block and top is circumscribed, greatly even if test block quality It can smoothly be rotated, therefore testing staff can be changed without test pose and can be easily accomplished to the 100% of simulating test pieces inspection It surveys.Test block can also be rotated at any time, and precise measurement is carried out to specified defect or two approximate defects are compared into detection, and When carrying out defect location using graduated scale, scale can be looked squarely always, reduce position error.

(3) long slot hole is arranged in plane on bracket, and two idler wheel spacing in same long slot hole are adjustable, so that the bracket can be put Set the simulating test pieces of various outer diameter, strong applicability.

(4) scroll wheel is set below bracket, bracket easily can be moved on into specific position, using and receiving convenient for test block It receives.

Bolt is realized by the first nut and the second nut and is fixed with frame, by changing position of first nut on bolt It sets and realizes that support wheel height is adjustable, detected with adapting to the tester of different height requirement, detection operating condition is not likely to produce well tired Labor.

(5) scroll wheel has brake block, and the fixation of bracket at an arbitrary position may be implemented, facilitate and accurately detected, subtracted Less because of scroll wheel activity bring detection error.
