Description

Technical Field

[0001] This utility model relates to the technical field of ultrasonic testing auxiliary devices, specifically to an ultrasonic testing auxiliary device for small-diameter bars. Background Technology

[0002] Currently, ultrasonic testing is widely used in non-destructive testing of metal bars due to its high efficiency and accuracy. Existing technologies primarily employ fixed roller frames to support the bars during ultrasonic testing of small-diameter bars. During the ultrasonic testing process, a motor drives the rollers to rotate the bar, resulting in high testing efficiency. However, this equipment is bulky, inconvenient to move, and has high manufacturing costs, making it difficult to popularize in small and medium-sized enterprises or on-site testing. Utility Model Content

[0003] The purpose of this invention is to provide an auxiliary device for ultrasonic testing of small-diameter bars, in order to solve at least one of the aforementioned problems in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An auxiliary device for ultrasonic testing of small-diameter bars includes a lower base, an upper base, and a U-shaped buckle. The lower end face of the lower base is a lower plane, and the upper end face of the lower base has an upper contact surface and an upper stepped surface. The height of the upper contact surface is lower than the height of the upper stepped surface. A plurality of first through holes are provided vertically and at intervals on the upper contact surface. A first roller frame is provided on the upper stepped surface, and a first roller is provided on the first roller frame. The first roller is located to the right of the first through holes.

[0006] The upper surface of the upper base is a flat surface. Multiple second through holes are provided vertically and at intervals on the flat surface. A second roller frame is provided on the flat surface. A second roller is provided on the second roller frame. The second roller is located to the left of the second through holes. The lower surface of the upper base has a lower contact surface and a lower step surface. The height of the lower contact surface is higher than the height of the lower step surface. The lower step surface is flush with the lower flat surface.

[0007] After the upper and lower mating surfaces are aligned and the first and second through holes are aligned, the U-shaped buckle is inserted into the corresponding first and second through holes to adjust the distance between the first and second rollers.

[0008] In this technical solution, the upper surface of the lower base has an upper mating surface and an upper stepped surface, with the height of the upper mating surface lower than the height of the upper stepped surface. The lower surface of the upper base has a lower mating surface and a lower stepped surface, with the height of the lower mating surface higher than the height of the lower stepped surface. The upper mating surface of the lower base can be mated and fitted with the lower mating surface of the upper base. In the mated state, the lower stepped surface is flush with the lower plane. The combined upper and lower bases can be placed stably on the ground, improving the stability for subsequent use. A first roller frame is provided on the upper stepped surface, with a first roller on the frame, located to the right of the first through hole. A second roller frame is provided on the upper plane, with a second roller on the frame, located to the left of the second through hole. In the combined state of the upper and lower bases, the first and second rollers are located on opposite sides of the combined base. The small-diameter bar is placed between the first and second rollers, which provide support for the small-diameter bar without affecting its rotation. Because the upper mating surface has multiple first through holes spaced vertically, and the upper end surface of the upper base is a flat surface with multiple second through holes spaced vertically, after the upper and lower mating surfaces are aligned and the first and second through holes are aligned, the U-shaped buckle is inserted into the corresponding first and second through holes to adjust the distance between the first and second rollers. The U-shaped buckle can lock the positional relationship between the upper and lower bases. The roller distance can be quickly adjusted by adjusting the insertion position of the U-shaped buckle to accommodate bars of different diameters. By adjusting the insertion position of the U-shaped buckle, the distance between the first and second rollers can be adjusted to accommodate pipe diameters of different small-diameter bars. In addition, the lower base and the upper base are separate structures. During on-site inspection, this auxiliary device can be carried to the stacking location of the bars as needed. This auxiliary device is detachable, compact, lightweight, easy to move and carry, and reduces the labor intensity of operators. In addition, after the bar is placed on the auxiliary device, it can only roll in place between the two rollers and will not move forward, backward or left or right. The position of the bar is fixed, which can protect the personnel's hands and feet from being squeezed, thus improving the safety of use.

[0009] In summary, this technical solution allows the two ends of the bar to be placed on an auxiliary device with rollers, facilitating rolling detection and significantly improving detection efficiency. Furthermore, it is detachable, compact, lightweight, and easy to move and carry, reducing the labor intensity of operators. Its simple structure and low cost make it suitable for widespread use by small and medium-sized enterprises.

[0010] Furthermore, in order to improve the locking effect of the upper and lower bases, both the first and second through holes are rectangular holes, and the shape of the U-shaped buckle matches the rectangular holes.

[0011] Furthermore, in order to improve the locking effect of the U-shaped buckle, the lower base is provided with four first through holes, and the upper base is provided with four second through holes.

[0012] Furthermore, to enhance the locking effect of the U-shaped buckle, the first and second through holes are the same size and have the same spacing.

[0013] Furthermore, the upper and lower bases are made of high-strength aluminum alloy, which is lightweight and corrosion-resistant.

[0014] Furthermore, the roller surface is covered with a rubber layer to increase friction and protect the surface of the rod.

[0015] Furthermore, the U-shaped buckle is made of stainless steel to ensure strength and durability.

[0016] The beneficial effects of this utility model are as follows: In this technical solution, the upper end surface of the lower base has an upper contact surface and an upper stepped surface, with the height of the upper contact surface lower than the height of the upper stepped surface. The lower end surface of the upper base has a lower contact surface and a lower stepped surface, with the height of the lower contact surface higher than the height of the lower stepped surface. The upper contact surface of the lower base can be in contact with the lower contact surface of the upper base, and in the contacted state, the lower stepped surface is flush with the lower plane. Therefore, the upper and lower bases can be placed stably on the ground when combined, improving stability for subsequent use. Because a first roller frame is provided on the upper stepped surface, and a first roller is provided on the first roller frame, located to the right of the first through hole, and a second roller frame is provided on the upper plane, with a second roller provided on the second roller, located to the left of the second through hole, in the combined state of the upper and lower bases, the first and second rollers are located on opposite sides of the combined base. The small-diameter bar is placed between the first and second rollers, providing support for the small-diameter bar without affecting its rotation. Because the upper mating surface has multiple first through holes spaced vertically, and the upper end surface of the upper base is a flat surface with multiple second through holes spaced vertically, after the upper and lower mating surfaces are aligned and the first and second through holes are aligned, the U-shaped buckle is inserted into the corresponding first and second through holes to adjust the distance between the first and second rollers. The U-shaped buckle can lock the positional relationship between the upper and lower bases. The roller distance can be quickly adjusted by adjusting the insertion position of the U-shaped buckle to accommodate bars of different diameters. By adjusting the insertion position of the U-shaped buckle, the distance between the first and second rollers can be adjusted to accommodate pipe diameters of different small-diameter bars. In addition, the lower base and the upper base are separate structures. During on-site inspection, this auxiliary device can be carried to the stacking location of the bars as needed. This auxiliary device is detachable, compact, lightweight, easy to move and carry, and reduces the labor intensity of operators. In addition, after the bar is placed on the auxiliary device, it can only roll in place between the two rollers and will not move forward, backward or left or right. The position of the bar is fixed, which can protect the personnel's hands and feet from being squeezed, thus improving the safety of use.

[0017] In summary, this technical solution allows the two ends of the bar to be placed on an auxiliary device with rollers, facilitating rolling detection and significantly improving detection efficiency. Furthermore, it is detachable, compact, lightweight, and easy to move and carry, reducing the labor intensity of operators. Its simple structure and low cost make it suitable for widespread use by small and medium-sized enterprises. Attached Figure Description

Detailed Implementation

[0024] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0025] Example 1:

[0026] like Figures 1-5 As shown, this embodiment provides an auxiliary device for ultrasonic testing of small-diameter bars, including a lower base 1, an upper base 2 and a U-shaped buckle 3. The lower end surface of the lower base 1 is a lower plane 4, and the upper end surface of the lower base 1 has an upper contact surface 5 and an upper step surface 6. The height of the upper contact surface 5 is lower than the height of the upper step surface 6. The upper contact surface 5 is provided with a plurality of first through holes 7 at intervals. The upper step surface 6 is provided with a first roller frame 8, and the first roller frame 8 is provided with a first roller 9. The first roller 9 is located to the right of the first through holes 7.

[0027] The upper end surface of the upper base 2 is an upper plane 10. Multiple second through holes 11 are provided on the upper plane 10 at intervals. A second roller frame 12 is provided on the upper plane 10. A second roller 13 is provided on the second roller frame 12. The second roller 13 is located to the left of the second through holes 11. The lower end surface of the upper base 2 has a lower contact surface 14 and a lower step surface 15. The height of the lower contact surface 14 is higher than the height of the lower step surface 15. The lower step surface 15 is flush with the lower plane 4. The upper plane 10 is flush with the upper step surface 6.

[0028] After the upper bonding surface 5 and the lower bonding surface 14 are mated and the first through hole 7 and the second through hole 11 are aligned, the U-shaped buckle 3 is inserted into the corresponding first through hole 7 and second through hole 11 to adjust the distance between the first roller 9 and the second roller 13.

[0029] In this technical solution, the upper surface of the lower base 1 has an upper mating surface 5 and an upper stepped surface 6, with the height of the upper mating surface 5 being lower than the height of the upper stepped surface 6. The lower surface of the upper base 2 has a lower mating surface 14 and a lower stepped surface 15, with the height of the lower mating surface 14 being higher than the height of the lower stepped surface 15. The upper mating surface 5 of the lower base 1 can be mated and fitted with the lower mating surface 14 of the upper base 2. In the mated state, the lower stepped surface 15 is flush with the lower plane 4. The combined upper base 2 and lower base 1 can be placed stably on the ground, improving the stability for subsequent use. It should be noted that in this technical solution, "matting" in the mating surface means that in the combined state of the upper and lower bases, the upper mating surface 5 and the lower mating surface 14 are in a positionally mated state. Since the upper step surface 6 is provided with a first roller frame 8, the first roller frame 8 is provided with a first roller 9, the first roller 9 is located on the right side of the first through hole 7, the upper plane 10 is provided with a second roller frame 12, the second roller frame 12 is provided with a second roller 13, the second roller 13 is located on the left side of the second through hole 11, in the combined state of the upper base 2 and the lower base 1, the first roller 9 and the second roller 13 are respectively located on both sides of the combined base, the small diameter bar 16 is placed between the first roller 9 and the second roller 13, the first roller 9 and the second roller 13 provide support for the small diameter bar 16, and do not affect the rotation of the small diameter bar 16. Because the upper mating surface 5 has multiple first through holes 7 spaced vertically, and the upper end surface of the upper base 2 is an upper plane 10, with multiple second through holes 11 spaced vertically on the upper plane 10, after the upper mating surface 5 and the lower mating surface are connected and the first through holes 7 and second through holes 11 are aligned, the U-shaped buckle 3 is inserted into the corresponding first through hole 7 and second through hole 11 to adjust the distance between the first roller 9 and the second roller 13. The U-shaped buckle 3 can lock the positional relationship between the upper base 2 and the lower base 1. The roller distance can be quickly adjusted by adjusting the insertion position of the U-shaped buckle 3 to accommodate rods 16 of different diameters. Depending on the insertion position of the U-shaped buckle 3, the distance between the first roller 9 and the second roller 13 can be adjusted to accommodate tube diameters of rods 16 of different small diameters. In addition, the lower base 1 and the upper base 2 are separate structures. During on-site testing, this auxiliary device can be carried to the stacking position of the rods 16 as needed. This auxiliary device is detachable, compact, lightweight, easy to move and carry, and reduces the labor intensity of operators. In addition, after the rod 16 is placed on the auxiliary device, the rod 16 can only roll in place between the two rollers and will not move forward, backward or left or right. The position of the rod 16 is fixed, which can protect the personnel's hands and feet from being squeezed, thus improving the safety of use.

[0030] In summary, this technical solution allows the two ends of the bar 16 to be placed on an auxiliary device with rollers, facilitating rolling detection and significantly improving detection efficiency. It is also detachable, compact, lightweight, and easy to move and carry, reducing the labor intensity of operators. The structure is simple and the cost is low, making it suitable for widespread use by small and medium-sized enterprises.
