Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example

[0020] Please see Figure 1 - Figure 6The ultrasonic phased array inspection track for TKY pipe joint welds includes: Base 1; A fixing component 2 is set above the base 1, and the TKY tube is fixed to the base 1 by the fixing component 2; The left-right moving component 3 is set on the base 1; A mounting bracket 4 is fixedly installed on the left and right moving component 3; A forward and backward moving component 5 is mounted on the fixed frame 4; The first U-shaped frame 6 is fixedly connected to the front and rear moving assembly 5; The lifting assembly 7 is located on one side of the first U-shaped frame 6; A rotating component 8 is located on one side of the lifting component 7; A rotary cylinder 9 is fixedly installed on one side of the rotary assembly 8; A square plate 10 is fixedly connected to the output end of the rotary cylinder 9; A second L-shaped plate 11 is fixedly installed on one side of the square plate 10; And the detection probe 12 is fixedly installed at the bottom of the second L-shaped plate 11.

[0021] The ultrasonic phased array inspection track for TKY pipe joint welds provided by this utility model is used in the following way: The pipe is fixed to the base 1 by the fixing component 2, and then the left-right moving component 3 moves the fixing frame 4 left and right, allowing the inspection probe 12 to move to the spot weld of the pipe. Then, the front-back moving component 5 is activated, causing the first U-shaped frame 6 to move back and forth, so that the inspection probe 12 is positioned directly above the spot weld. Next, the lifting component 7 lowers the rotating component 8, allowing the inspection probe 12 to contact and inspect the pipe. Then, when the inspection probe 12 inspects the side of the pipe, the lifting component 7 first raises the rotating component 8, then activates the rotating component 8, causing the rotating cylinder 9 to rotate 180 degrees around the lifting component 7. Finally, the rotating cylinder 9 moves the square plate 10, which, through the second L-shaped plate 11, allows the inspection probe 12 to be tilted, thus providing more comprehensive coverage of the weld area. This device can inspect not only straight pipes but also TKY pipes, improving inspection accuracy and expanding the applicability of the equipment.

[0025] Specifically, when the electric push rod 25 moves the rectangular plate 23 connected to it, the first rack 18 moves synchronously. Then, the moving first rack 18 drives the gear 20 on the cylindrical rod, so that the gear 20 can drive another rectangular plate 23 and the clamping frame 24 to move through the second rack 19 that meshes with it.

[0026] Furthermore, the left and right moving component 3 includes two third slide rails 31 symmetrically fixedly installed on the inner top wall of the base 1.

[0027] Specifically, the first motor 34 drives the second screw 33 to rotate, and the rotating second screw 33, under the action of the third slide rail 31, can stably drive the rectangular column 32 connected to it by threads, so that the rectangular column 32 can stably drive the fixed frame 4 to move under the action of the third slide rail 31, thereby enabling the detection probe 12 to be adjusted left and right.

[0028] Furthermore, the forward and backward moving assembly 5 includes a fourth slide rail 51 fixedly installed on the inner top wall of the fixed frame 4.

A second motor 54 is fixedly installed on one side of the fixed frame 4, and the output end of the second motor 54 is fixedly connected to the third screw 53.

[0029] Specifically, the second motor 54 drives the third screw 53 to rotate, and the rotating third screw 53, under the action of the fourth slide rail 51, can stably drive the fixed block 52 connected to it by threads, so that the fixed block 52 can stably drive the first U-shaped frame 6 to move under the action of the fourth slide rail 51, thereby enabling the detection probe 12 to be adjusted back and forth.

[0030] Furthermore, the lifting assembly 7 includes a dual-axis cylinder 71 fixedly installed on one side of the first U-shaped frame 6, and the output end of the dual-axis cylinder 71 is fixedly connected to a third L-shaped plate 72.

[0031] Specifically, the third L-shaped plate 72 is lowered by the dual-axis cylinder 71, so that the detection probe 12 can approach and contact the pipe held on the fixing component 2, thereby facilitating the detection of the pipe.

[0032] Furthermore, the rotating assembly 8 includes a mounting bracket 81 fixedly installed on one side of the third L-shaped plate 72, a third motor 82 fixedly installed on the mounting bracket 81, the output end of the third motor 82 fixedly connected to the inverted L-shaped plate 83, and a rotating cylinder 9 fixedly installed on one side of the inverted L-shaped plate 83.

[0033] Specifically, the third motor 82 on the mounting bracket 81 drives the inverted L-plate 83, which in turn drives the rotary cylinder 9 to rotate 180 degrees around the lifting assembly 7, thereby enabling the detection probe 12 to be adjusted at multiple angles. Example
