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

[0024] Please see Figures 1-4 This utility model provides a technical solution for an ultrasonic testing device for weld defects in steel structures: an ultrasonic testing device for weld defects in steel structures includes an equipment base 1, a rotating motor 2 fixedly installed in the inner cavity of the equipment base 1 via a frame, a connecting rod 3 fixedly installed at the output shaft end of the rotating motor 2, a movable sleeve 4 slidably installed on the side wall of the connecting rod 3, a sliding groove 11 opened in the inner cavity of the equipment base 1, a sliding column 12 slidably installed in the inner cavity of the sliding groove 11, a guide wheel 13 fixedly installed at the end of the sliding column 12, a walking component 5 provided in the inner cavity of the equipment base 1, and a detection component 6 provided on the side wall of the movable sleeve 4.

[0025] Furthermore, the walking assembly 5 includes a connecting seat 51 fixedly installed at the end of the sliding column 12, a connecting rod 52 rotatably installed on the side wall of the connecting seat 51, a central platform 53 rotatably installed in the middle of the bottom surface of the inner cavity of the equipment base 1, and an electric push rod 54 provided between the connecting seats 51 on the front and rear sides.

[0026] The connecting seat 51 slides in the inner cavity of the sliding groove 11. There are a total of 4 sets of connecting rods 52. The connecting rods 52 are arranged in an L-shape. The end of the connecting rod 52 away from the connecting seat 51 is rotatably mounted on the side wall of the central platform 53. The sleeve end of the electric push rod 54 is fixedly connected to the rear connecting seat 51, and the rod end of the electric push rod 54 is fixedly connected to the front connecting seat 51.

[0027] There are four sets of guide wheels 13, and each set of guide wheels 13 has a drive motor 14 installed on the shaft end.

[0028] It should be noted that when the worker places the entire device into the steel structure pipe, the electric push rod 54 can be activated to move the connecting seats 51 on the front and rear sides away from each other. Since the connecting rod 52 is rotatably installed on the side wall of the connecting seat 51, and the end of the connecting rod 52 away from the connecting seat 51 is rotatably installed on the side wall of the central platform 53, the central platform 53 will rotate under the limiting action of the four sets of connecting rods 52, and the connecting seats 51 on all sides will slide outwards towards the sliding groove 11. That is, the circumcircle formed by the sliding column 12 will continuously increase, so that the guide wheel 13 can firmly abut against the inner wall of the steel structure pipe. With the setting of the walking motor 14, the guide wheel 13 can be rotated. At this time, the entire device can realize the function of moving independently inside the steel structure pipe.

[0029] Furthermore, the detection component 6 includes a first lug 61 fixedly installed on the side wall of the movable sleeve 4, and an auxiliary rod 62 rotatably installed in the inner cavity of the first lug 61. A second lug 63 is fixedly installed on the upper part of the side wall of the connecting rod 3. A rotating rod 64 is rotatably installed in the inner cavity of the second lug 63. An ultrasonic detection plate 65 is rotatably installed at the end of the rotating rod 64.

[0030] The end of the auxiliary rod 62 away from the first lug 61 is rotatably mounted in the middle of the side wall of the rotating rod 64. A locking block 66 is threadedly installed on the side wall of the movable sleeve 4, and the end face of the locking block 66 can abut against the side wall of the connecting rod 3.

[0031] It should be noted that the worker can remove the locking block 66 from the sliding sleeve 4. At this time, the sliding sleeve 4 and the connecting rod 3 will be in a sliding state. When the sliding sleeve 4 moves on the side wall of the connecting rod 3, the included angle between the auxiliary rod 62 and the rotating rod 64 will change, so that the position of the ultrasonic detection plate 65 installed on the connecting rod 3 will keep changing to suit steel structure pipes with different inner diameters, which greatly improves the convenience of the whole equipment. After the position of the ultrasonic detection plate 65 is determined, the locking block 66 can be tightened again to lock the sliding sleeve 4.

[0032] Furthermore, a lighting lamp 31 is fixedly installed at the end of the connecting rod 3, an ultrasonic detector 7 is fixedly installed on the upper surface of the equipment base 1, and a power cord 8 is fixedly installed on the lower surface of the equipment base 1. The power cord 8 and the ultrasonic detection plate 65 are both electrically connected to the ultrasonic detector 7.

[0033] Working principle:

[0034] Before starting work, the worker can remove the locking block 66 from the sliding sleeve 4. At this time, the sliding sleeve 4 and the connecting rod 3 will be in a sliding state. When the sliding sleeve 4 moves on the side wall of the connecting rod 3, the angle between the auxiliary rod 62 and the rotating rod 64 will change, so that the position of the ultrasonic detection plate 65 installed on the connecting rod 3 will keep changing, so as to be suitable for steel structure pipes with different inner diameters, which greatly improves the convenience of the whole equipment. After the position of the ultrasonic detection plate 65 is determined, the locking block 66 can be tightened again to lock the sliding sleeve 4.

[0035] During operation, the worker places the entire device into the steel structure pipe. By activating the electric push rod 54, the connecting seats 51 on the front and rear sides can be moved away from each other. Since the connecting rod 52 is rotatably installed on the side wall of the connecting seat 51, and the end of the connecting rod 52 away from the connecting seat 51 is rotatably installed on the side wall of the central platform 53, the central platform 53 will rotate under the limiting action of the four sets of connecting rods 52. At the same time, the connecting seats 51 around the device slide outwards from the sliding groove 11. That is, the circumcircle formed by the sliding column 12 will continuously increase, so that the guide wheel 13 can firmly abut against the inner wall of the steel structure pipe. With the setting of the walking motor 14, the guide wheel 13 can be rotated. At this time, the entire device can realize the function of moving independently inside the steel structure pipe.

[0036] When the entire device moves inside the steel structure pipeline, the rotating motor 2 is turned on simultaneously, causing the ultrasonic detection plate 65 on the connecting rod 3 to rotate. At this time, the ultrasonic detector 7 is turned on, which can realize the function of detecting the weld seam of the steel structure pipeline. It is convenient and quick. With the setting of the lighting lamp 31, the internal condition of the steel structure pipeline can be observed, which makes it convenient for workers to take corresponding actions in a timely manner.

[0037] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
