Description

Technical Field

[0001] This utility model relates to the technical field of seamless steel pipe flaw detection equipment, and in particular to a transverse trolley for an ultrasonic flaw detector. Background Technology

[0002] Ultrasonic flaw detectors are typically moved by a traverse carriage to inspect seamless steel pipes. Due to space limitations above the traverse carriage, the power distribution cabinet is installed behind the wheel support frame. When the seamless steel pipe is inspected by the GE ultrasonic flaw detector, the traverse carriage frame shakes significantly during movement. This unevenness in the carriage frame causes uneven stress on the wheels, leading to long-term overload damage to the rear wheels. After wheel damage, a professional team must be outsourced to disassemble and replace the entire carriage, which is difficult and costly. The ordinary wheel bearings used as temporary replacements cannot meet the on-site requirements, are prone to damage, and frequently fail, seriously affecting the flaw detection efficiency.

[0026] like Figures 1 to 5 As shown, according to an embodiment of this utility model, a transverse trolley for an ultrasonic flaw detector is provided. The ultrasonic flaw detector has a main probe frame 9, on which flaw detection equipment is mounted. The transverse trolley can drive the main probe frame 9 to move on a track beam 11, as shown. Figure 2 As shown, the traverse trolley includes a base 1, a support arm 4, and an electrical control box 10, wherein, as Figure 3 As shown, a first roller group 2 is provided below the base 1, allowing the base 1 to move on the track beam 11 via the first roller group 2; one end of the support arm 4 is connected to one end of the base 1, and the other end of the support arm 4 is connected to the main probe frame 9; the power distribution box 10 is located on the support arm 4, and there is a distance between the support arm 4 and the track beam 11. The traverse trolley drives the main probe frame 9 to move on the track beam 11, enabling the flaw detection equipment to perform flaw detection on seamless steel pipes during movement. The power distribution box 10 is used to provide power to the ultrasonic flaw detector.

[0027] Furthermore, such as Figure 4 As shown, mounting portions 12 are provided on both sides of the base 1. The base 1 and the mounting portions 12 are an integral structure. A second roller group 3 is provided below each mounting portion 12. The second roller group 3 is used to position the base 1. The two second roller groups 3 clamp the track beam 11 on both sides, thereby ensuring that the base 1 remains horizontal during movement. This design solves the problem of large swaying of the main probe frame 9 caused by unreasonable weight distribution during the movement of the existing trolley.

[0028] Furthermore, the first roller assembly 2 includes two first guide rollers, which are sequentially arranged along the axial direction of the track beam 11. One first guide roller is a standard needle roller, and the other is an eccentric guide roller. The first guide rollers are in contact with the upper surface of the track beam 11. The contact area between the eccentric guide roller and the track beam 11 is adjusted by adjusting the assembly clearance between the eccentric wheel shaft of the eccentric guide roller and the base 1, ensuring that both first guide rollers are in effective contact with the track beam 11 and that the force is uniform, thus preventing damage to a single first guide roller due to excessive load.

[0029] Furthermore, the second roller assembly 3 includes two second guide rollers, which are sequentially arranged along the axial direction of the track beam 11. One second guide roller is a standard needle roller, and the other is an eccentric guide roller. The second guide rollers contact the sidewall of the track beam 11. By adjusting the assembly clearance between the eccentric wheel shaft of the eccentric guide roller and the base 1, the contact area between the eccentric guide roller and the track beam 11 is adjusted, ensuring that all four second guide rollers are in effective contact with the track beam 11, resulting in uniform force and preventing damage to individual second guide rollers due to excessive load.

[0030] Furthermore, the axis of the first guide roller's axle is perpendicular to the axis of the second guide roller's axle.

[0031] Furthermore, such as Figure 3 As shown, guide wheel lubrication units 5 are provided on the outer sides of both the first and second guide rollers, and the guide wheel lubrication units 5 are connected to the base 1. The guide wheel lubrication units 5 can add lubricating oil to the first or second guide roller.

[0032] Furthermore, the distribution box 10 and the support arm 4 are connected by welding.

[0033] Furthermore, such as Figure 5 As shown, the support arm 4 and the base 1 are connected by a connecting plate 13.

[0034] Furthermore, it also includes a positioning block 6, which includes a vertical section 14 and a horizontal section 15. The lower end of the vertical section 14 is connected to the upper end of the base 1, and the upper end of the vertical section 14 is connected to one end of the horizontal section 15. The other end of the horizontal section 15 extends upward toward the connecting plate 13. The upper end of the connecting plate 13 is provided with a bolt hole. The adjusting bolt 7 passes through the horizontal section 15 and is screwed into the bolt hole. An adjusting nut 16 is fitted on the adjusting bolt 7. The adjusting nut 16 is located above the horizontal section 15. Rotating the adjusting nut 16 can finely adjust the position of the support arm 4 relative to the base 1.

[0035] Furthermore, the support arm 4 is connected to the connecting plate 13 by multiple fastening bolts 8.

[0036] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0037] A transverse trolley for an ultrasonic flaw detector is disclosed. The transverse trolley has a simple structure, is easy to install, maintain, and disassemble, and can effectively reduce the problems of large shaking of the main probe frame 9 and the easy damage caused by uneven long-term stress on the first guide roller and the second guide roller. It greatly improves the service life of the first guide roller and the second guide roller and improves the stability of the transverse trolley operation.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
