Embodiment 1

[0029] In order to make the present invention clearer, a hand-held ultrasonic testing device for steel plates of the present invention will be further described below. The specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0030] Such as figure 1 As shown, a hand-held ultrasonic detection device for steel plates includes a sliding left bracket 2, a beam 1 and a sliding right bracket 3 that cooperate with each other, and is characterized in that:

[0031] see Figure 1~Figure 3 , the sliding left bracket 2 and the sliding right bracket 3 are connected in parallel on both sides of the beam 1, the sliding left bracket 2 and the sliding right bracket 3 are the same in size and shape, and both are arranged perpendicular to the beam 1;

[0032] The left end of the crossbeam 1 is connected with a left baffle 4, and the right end is connected with a right baffle 5, so as to limit the left and righ...

Abstract

The invention relates to a steel plate handheld ultrasonic detection device which comprises a left sliding support (2), a cross beam (1) and a right sliding support (3) which are matched with one another, a vertical displacement support (9), a vertical guide rail (10), a transverse moving support (11) and a scale ruler (18) are further sequentially arranged on the cross beam (1), and an adjusting lead screw (14) is connected between a left vertical plate (12) and a right vertical plate (13) at the two ends of the transverse moving support (11). A left probe clamping block (15) and a right probe clamping block (16) which are matched with each other are connected to the adjusting screw rod (14) and are connected with a transverse moving guide rail (17) connected to the transverse moving bracket (11). The device has the advantages of small detection blind area, strong resolution, high detection sensitivity and fast detection speed, optimizes the steel plate detection process, improves the production efficiency, enhances the quality control of the steel plate, and provides powerful guarantee for the quality improvement of steel binding and steelmaking.

Description

technical field [0001] The invention relates to the technical field of steel plate non-destructive testing equipment, in particular to a hand-held ultrasonic testing device for steel plates. Background technique [0002] With the rapid development of my country's economy, all walks of life have more and more demand for steel plate products, and their quality requirements are becoming more and more stringent. In the process of steel rolling and steelmaking, in order to control the quality of the steel plate, it is necessary to carry out 100% ultrasonic TOFD inspection on the inside of the steel plate. At present, on-line ultrasonic inspection of steel plates often causes alarms, and manual re-inspection is required. Conventional manual re-inspection is difficult to meet the detection requirements and detection efficiency, and it is easy to cause unqualified batches of steel plates due to untimely re-inspection. Contents of the invention [0003] The purpose of the present ...
