Description

Technical Field

[0001] The utility model belongs to the technical field of railway wheel rim detection devices, and in particular relates to a rim scanning shear wave adjustment-free probe bracket. Background Art

[0002] Currently, when using the ultrasonic water immersion method to inspect wheel rims, the scanning mechanism must move along the inclination angle of the rim tread, while the shear wave probe must be parallel to the tread. The conventional probe installation method involves inserting the probe's rotating shaft into a fixed, clampable axle seat. Once the probe is in place, the angle must be finely adjusted and then secured with a set screw. Whether installing the probe for the first time or replacing it, the axle seat locking screw must be loosened and the probe removed. However, when reinstalling the probe, the original installation angle is difficult to maintain, requiring further fine-tuning and tightening of the screws, which is quite cumbersome. Utility Model Content

[0003] The purpose of the utility model is to provide a rim scanning shear wave adjustment-free probe holder, which can accurately and stably install and replace the probe, and only needs to fine-tune the probe during the initial installation. When the probe is replaced, the probe posture can maintain the previous state, eliminating the need for fine-tuning again.

[0004] In order to achieve the above technical objectives, the technical solutions adopted by this utility model are as follows:

[0005] A rim scanning shear wave adjustment-free probe bracket includes an intermediate transition block, a transition block shaft, an axle seat, and an axle seat fixing beam. The transition block shaft is fixedly connected to the side wall of the intermediate transition block. An intermediate transition block center hole is provided in the middle of the intermediate transition block and the transition block shaft. An axle seat hole is provided in the middle of the axle seat. The transition block shaft is inserted into the axle seat hole. The axle seat is connected to axle seat hole locking screw and axle seat fixing screw. A screw hole is provided on the axle seat fixing beam. The axle seat is connected to the axle seat fixing beam via the axle seat fixing screw.

[0006] It is further defined that the other side wall of the intermediate transition block is provided with an intermediate transition block square opening. In this way, the intermediate transition block square opening cooperates with the probe housing so that the probe shaft cannot rotate relative to the probe shaft after being inserted into the central hole of the intermediate transition block and can only be inserted and removed.

[0007] It is further defined that the number of the axle seat fixing screws is two, which makes the axle seat more stable and improves the detection accuracy.

[0008] It is further defined that the shaft seat hole locking screw and the shaft seat fixing screw are both hexagon socket screws. Hexagon socket screws can withstand greater loads and are easy to install.

[0009] It is further defined that a gasket is connected to the side wall of the intermediate transition block.

[0010] Compared with the existing technology, the utility model can accurately and stably install and replace the probe, and the probe needs to be fine-tuned only during the initial installation. When the probe is replaced, the posture of the probe can be maintained in the previous state, eliminating the need for fine-tuning again. The structure is simple, easy to operate and maintain, and saves labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0017] Example

[0018] The utility model provides a rim scanning shear wave adjustment-free probe bracket, which can accurately and stably install and replace the probe 1, and only needs to fine-tune the probe 1 during the initial installation. When the probe 1 is replaced, the posture of the probe 1 can maintain the previous state, eliminating the process of fine-tuning again. The device includes an intermediate transition block 2, a transition block shaft 4, an axle seat 6, and an axle seat fixing beam 10. The transition block shaft 4 is fixedly connected to the side wall of the intermediate transition block 2. An intermediate transition block square opening 11 is provided on the other side wall of the intermediate transition block 2, and a washer 13 is also connected. An intermediate transition block center hole 3 is provided in the middle of the intermediate transition block 2 and the transition block shaft 4. A axle seat hole 7 is provided in the middle of the axle seat 6. The transition block shaft 4 is inserted into the axle seat hole 7. The axle seat 6 is connected with a axle seat hole locking screw 8 and axle seat fixing screw 9. Both the axle seat hole locking screw 8 and the axle seat fixing screw 9 are hexagon socket screws. There are two axle seat fixing screws 9. A screw hole is provided on the axle seat fixing beam 10. The axle seat 6 is connected to the axle seat fixing beam 10 through the axle seat fixing screw 9.

[0019] The working principle of this utility model is:

[0020] The probe 1 includes a probe shell 12 and a probe shaft 5. The probe shaft 5 is mounted on the probe shell 12 and inserted into the center hole 3 of the intermediate transition block. The probe shaft 5 cooperates with the center hole 3 of the intermediate transition block and can be pulled out freely. At the same time, the probe shell 12 is inserted into the square opening 11 of the intermediate transition block. The square opening 11 of the intermediate transition block cooperates with the probe shell 12, so that the probe shaft 5 cannot rotate relative to each other after being inserted into the center hole 3 of the intermediate transition block and can only be inserted and pulled out. The transition block shaft 4 is inserted into the shaft seat hole 7. The transition block shaft 4 cooperates with the shaft seat hole 7 and can rotate relative to each other to adjust the angle of the probe 1. After turning to the appropriate angle, it is locked with the shaft seat locking screw 8. The shaft seat fixing screw 9 fixes the shaft seat 6 to the shaft seat fixing beam 10, while limiting the movement of the probe 1 along the axis.

[0021] When replacing the probe, there is no need to loosen the shaft seat locking screw 8. Only the shaft seat fixing screw 9 is needed. The shaft seat 6, intermediate transition block 2, and transition block shaft 4 can be removed together. The probe shaft 5 can then be pulled out and the old probe 1 removed. Since the shaft seat 6, intermediate transition block 2, and transition block shaft 4 are not loosened, their angular relationship is maintained. After installing the new probe 1, reinstall the shaft seat fixing screw 9. The angle of the new probe is now consistent with the old one. Since the old probe's angle has been finely adjusted, the angle of the new probe does not need to be fine-tuned again.

[0022] The above describes in detail the wheel rim scanning shear wave adjustment-free probe holder provided by the present invention. The description of the specific embodiments is intended only to facilitate understanding of the method and core concept of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications fall within the scope of protection of the claims of the present invention.
