The technology has the following problems in practical operation:
(1) when the dipperstick in the shell appears damaging, the measuring function of ultrasonic wave appearance can not be used, can't accomplish the judgement to the defective position, and it is long, the operation inconvenience brings certain inconvenience for the testing work to change the dipperstick in the shell.
(2) When the inspector examines, often need observe downwards on the ultrasonic apparatus and judge the horizontal position of reflection signal distance probe, at this moment, the chi strip of test ruler shelters from the position, is not convenient for observe the signal position, and when signal position when ultrasonic apparatus side observation, its scale that corresponds of dipperstick is difficult for observing, the deviation appears in the distance easily for measuring result is accurate inadequately.
SUMMERY OF THE UTILITY MODEL
The utility model provides an ultrasonic wave oblique probe detects special chi, when the dipperstick takes place to damage in aim at solving above-mentioned background art, changes convenient technical problem and observes the problem of guaranteeing the measuring accuracy under the inconvenient condition.
The technical scheme of the utility model is that: a special ultrasonic oblique probe detection ruler comprises: the ultrasonic probe comprises a fixing device, a ruler strip and a steel wire, wherein the fixing device is arranged on the ultrasonic probe and fixedly connected with the ruler strip, the middle part of the surface of the ruler strip is of a hollow structure with a rectangle, the steel wire is arranged on the ruler strip, the two ends of the steel wire are fixedly arranged at the two ends of the ruler strip and are located at the middle position of the hollow part of the ruler strip, the position point is arranged on the steel wire, and the position point corresponds to the scale positions at the two sides of the ruler strip.
Further, the fixing device is arranged at the top end outside the ultrasonic probe;
furthermore, the fixing device can be fixed on the ultrasonic probe in a mosaic, clamping and thread mode;
furthermore, the fixing device is a dovetail clamp corresponding to the surface width of the ultrasonic probe and is fixed at the top end of the ultrasonic probe in a clamping mode;
further, the length of the ruler strip can be intercepted according to the requirement of the detection condition;
furthermore, the length of the ruler strip is 10-200 mm;
further, the hollow rectangle of the ruler strip has the width of 3-5mm, and the length can be customized according to the detection requirement;
further, the steel wire is a soft steel wire with the diameter of 0.5mm, position points are arranged on the steel wire and have different colors, and the position points with different colors correspond to scales on the ruler strip.
The utility model has the advantages that:
(1) the ruler strip is connected with the ultrasonic probe through the fixing device, so that when the ruler strip is damaged, the fixing device can be directly removed from the ultrasonic probe, the ruler strip can be replaced, the dovetail clamp serving as the fixing device is very easy to obtain, and the operation is very simple, time-saving and labor-saving.
(2) The middle part of the ruler strip is a hollow rectangle, the position of the ultrasonic reflection signal can be observed through the hollow position, the problem that observation is inconvenient due to shielding of the ruler strip is solved, steel wires with different color position points are arranged at the two ends of the ruler strip, scales on the two sides of the ruler strip are marked through the position points with different colors, the distance and the length of the ultrasonic reflection signal are easily judged on the basis of convenient observation, and therefore a position conclusion with higher accuracy is obtained.
