Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of non-destructive testing blocks, in particular to a phased array non-destructive testing block support. BACKGROUND

[0002] Phased array non-destructive testing is a method of detecting internal defects in materials using multiple ultrasonic sensors (probes). It achieves comprehensive scanning of the detected material by controlling the excitation time of each probe and changing the propagation direction of the ultrasonic waves. When performing phased array non-destructive testing, a test block is needed to simulate a standardized test object of real materials to verify the performance of the testing equipment and simulate actual materials and defects. Before testing the non-destructive testing block, a support is needed to support the non-destructive testing block.

[0003] Currently, before pipeline non-destructive testing, testers usually use phased array test blocks to draw DAC curves. The phased array test block needs to be transported to the pipeline site. However, due to the large number of welds, each weld needs to be tested by a phased array test block. In order to reliably support the non-destructive testing block during pipeline non-destructive testing, patent No. CN202022230740.8 discloses a phased array non-destructive testing block support. The phased array non-destructive testing block support of this structure mainly realizes the installation and fixation of the test block on the support body through repeated insertion and repeated screwing of the nut locking. Then, by moving the external ultrasonic probe scanner along the scanning guide rail, non-destructive testing and detection of the test block is realized.

[0004] Although the existing phased array non-destructive testing block support can stably support the test block during pipeline non-destructive testing, the repeated insertion and repeated screwing of the nut for locking installation makes the installation efficiency of the test block on the support body relatively low, which is not convenient for efficient non-destructive testing and detection of the test block, and also not convenient for efficient disassembly and replacement of different test blocks on the support body.

[0027] Specifically, when the test block 4 to be tested is inserted into the installation slot 1, the limiting insertion columns 81 will pass through the through hole 5 and the insertion hole 7 in sequence and move downward, the limiting insertion columns 81 will press down the end part of the limiting clamping plate 84 through the limiting dials 82 while moving downward, and the end part of the limiting clamping plate 84 will be clamped into the corresponding limiting dials 82 on the limiting insertion columns 81 under the action of the spring shaft 85 after passing through each pair of limiting dials 82, thereby realizing the synchronous limiting of the limiting insertion columns 81, when the upper end face of the test block 4 to be tested is flush with the upper end face of the support body 3, the reliable limiting installation of the test block 4 to be tested in the installation slot 1 can be ensured under the action of the limiting clamping plate 84 and the limiting dial 82, at this time, the return spring 62 is in a state of slight compression, when the test block 4 to be tested needs to be replaced, the test block 4 to be tested is pressed downward into the installation slot 1, so that the return spring 62 continues to move downward by a distance under the action of the pressing plate 61, at the same time, the limiting clamping plate 84 is pushed out of the limiting dial 82, so as to ensure that the limiting clamping plate 84 is separated from the limiting dial 82, thereby realizing the contact limiting of the limiting insertion columns 81, then the limiting insertion columns 81 are lifted, so that the test block 4 to be tested extends out of the installation slot 1, and the test block 4 to be tested can be quickly disassembled, thereby facilitating the subsequent efficient replacement.

[0028] Please refer to Figure 1 and Figure 3The top end of the bracket body 3 is provided with a scanning guide rail 2 for cooperation with the ultrasonic probe scanner.

[0029] As an embodiment, the ultrasonic probe scanner for external detection is moved along the scanning guide rail 2, and the defects of the test block 4 can be conveniently and non-destructively detected.

[0030] Please refer to Figures 1-4 The installation groove 1 is matched with the shape of the test block 4, the insertion hole 7 penetrates the bracket body 3, and the insertion hole 7 is opposite to the center position of the through hole 5.

[0031] As an embodiment, the installation groove 1 is matched with the shape of the test block 4, which can ensure that the test block 4 can be accurately installed in the installation groove 1, and at the same time, when the test block 4 is installed, the limiting plug 81 can smoothly pass through the through hole 5.

[0032] Please refer to Figures 2-4 The bottom end of the reset spring 62 is welded to the bracket body 3, and the top end of the reset spring 62 is welded to the pressing plate 61.

[0033] As an embodiment, the reset spring 62 is mainly used to realize the automatic reset of the pressing plate 61 after the external force is removed, and at the same time, it can ensure the stable installation of the pressing plate 61 in the installation groove 1 without external force.

[0034] Please refer to Figures 1-4 The limiting plug 81 is welded to the test block 4, and the connecting part of the limiting plug 81 and the test block 4 is a cylindrical structure. The part of the limiting plug 81 connected with the limiting gear 82 is a columnar structure with two vertical sections.

[0035] As an embodiment, the welding fixing mode can ensure that the limiting plug 81 is installed synchronously with the movement of the test block 4, and the limiting gear 82 is installed at the section position of the limiting plug 81, which can ensure that the limiting gear 82 can have sufficient contact limiting area with the limiting clamping plate 84.

[0036] Please refer to Figures 1-4 The limiting gear 82 is welded to the limiting plug 81, and the size of the insertion hole 7 is larger than that of the limiting plug 81.

[0037] As an embodiment, when the limiting plug 81 moves downward, the limiting gear 82 will move downward synchronously and push the limiting clamping plate 84, so as to realize the rapid limiting of the test block 4 after installation when the limiting clamping plate 84 is clamped between two adjacent limiting gears 82.

[0038] Please refer to Figures 3-4 The hanger 83 is welded to the bracket body 3, and the inner upper side of the hanger 83 is an inclined structure facing away from the insertion hole 7.

[0039] As an implementation, the inclined structure on the hanger 83 enables the limiting plate 84 to rotate only in the direction away from the jack 7, thus ensuring the reliable limiting of the limiting plate 84 after it is engaged with the limiting gear 82.

[0040] Please refer to Figures 3-4 The spring shaft 85 is composed of a short shaft penetrating the limiting plate 84 and a clamping spring sleeved outside the short shaft. The spring shaft 85 is rotatably engaged with the hanger 83 through the short shaft, and is connected with the limiting plate 84 through the clamping spring.

[0041] As an implementation, the spring shaft 85 not only ensures the stable rotation of the limiting plate 84 relative to the inner pocket of the hanger 83, but also enables the automatic resetting of the limiting plate 84 after the external force is removed.

[0042] Please refer to Figures 1-4 The curvature of the test block 4, the mounting groove 1, the pressing plate 61, the bracket body 3 and the scanning guide rail 2 is the same.

[0043] As an implementation, the test block 4, the mounting groove 1, the pressing plate 61, the bracket body 3 and the scanning guide rail 2 with the same curvature can ensure that the external ultrasonic probe scanner can smoothly detect the defects of the test block 4.

[0044] Specific working principle is, in the nondestructive testing of the block 4 to be tested, first, the block 4 to be tested is inserted into the installation slot 1, when the block 4 to be tested is inserted into the installation slot 1, the limiting plug post 81 will pass through the through hole 5 and the insertion hole 7 in turn and move downward, the limiting plug post 81 will press down the end of the limiting clamping plate 84 through the limiting ratchet 82 while moving downward, the end of the limiting clamping plate 84 will be clamped into the corresponding limiting ratchet 82 between the limiting plug post 81 under the action of the spring shaft 85 after passing through a pair of limiting ratchets 82, so as to realize the synchronous limiting of the limiting plug post 81, when the upper end surface of the block 4 to be tested is flush with the upper end surface of the support body 3, the reliable limiting installation of the block 4 to be tested in the installation slot 1 can be ensured under the action of the limiting clamping plate 84 and the limiting ratchet 82, after the block 4 to be tested is installed, only need to make the external ultrasonic probe sweep the plug-in along the scanning guide rail 2, the block 4 to be tested can be nondestructively tested, when the block 4 to be tested needs to be replaced during the detection process, first, the block 4 to be tested is pressed downward into the installation slot 1, so that the reset spring 62 continues to move downward a distance under the action of the pressing plate 61, at the same time, the limiting clamping plate 84 is pushed out of the limiting ratchet 82, to ensure that the limiting clamping plate 84 is separated from the limiting ratchet 82, so as to realize the contact of the limiting of the limiting plug post 81, then only need to lift the limiting plug post 81, so that the block 4 to be tested extends out of the installation slot 1, the block 4 to be tested can be quickly disassembled to facilitate efficient replacement, because in this kind of installation mode, the tedious operation of repeatedly inserting and installing and repeatedly screwing the nut for locking when the block 4 to be tested is installed on the support body 3 is saved, so that the installation efficiency of the block 4 to be tested on the support body 3 is higher, the block 4 to be tested can be efficiently nondestructively tested, and different blocks 4 to be tested can be efficiently replaced.
