Description

Technical Field

[0001] This utility model relates to the field of train wheel technology, specifically a structure for measuring the wear of train wheels. Background Technology

[0002] Train wheels are important components of the train running system. Train wheels are in direct contact with the rails and are closely related to the safe operation of the train. Therefore, after a long period of use, it is necessary to test the wear of the train wheel tread to determine whether the train wheel can continue to be used.

[0003] Existing equipment requires disassembling train wheels for inspection, making the inspection process cumbersome and complex. This not only consumes significant time and manpower but also prevents trains from operating normally during inspection, affecting train usage and operational efficiency, and reducing the practicality of the equipment. An investigation revealed that a Chinese utility model patent (publication number: CN222850024U) discloses a train wheel wear measurement structure. By setting up a detection component, the angle and position of the detection head can be adjusted according to actual usage, allowing the detection head to detect the surface of the train wheel. This enables more accurate detection of the wear condition of the train wheel, avoids deviations in measurement data, and improves the detection effect of the train wheel.

[0004] However, during the inspection of train wheels, the aforementioned device, due to the fixing of the inspection component by the buffer assembly, can only inspect a single location on the train wheel and cannot inspect other parts of the train wheel, making it inconvenient to use.

[0005] Therefore, this utility model provides a structure for measuring the wear of train wheels to solve the above problems. Utility Model Content

[0006] This utility model provides a structure for measuring the wear of train wheels, aiming to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a train wheel wear measurement structure, including a wheel hub, and a fastening component is provided on the outer side of the wheel hub.

[0008] The fastening assembly includes a connecting block installed on the upper outer side of the wheel hub. Threaded rods are fixedly installed at both ends of the connecting block. A movable block is slidably connected to the outer side of the threaded rod. A fastening nut is threadedly connected to the outer side of the threaded rod on the opposite side of the two fastening nuts. A bracket is fixedly connected to the lower adjacent side of the two movable blocks. A side pressure wheel is rotatably connected inside the bracket. A threaded rod is threadedly connected inside the connecting block. A knob is fixedly connected to the top of the threaded rod, and a positive pressure wheel is rotatably connected to the bottom of the threaded rod.

[0009] As a preferred technical solution of this application, the threaded rod has a sliding groove on both the front and rear sides of its outer surface, and the upper end of the moving block has a protrusion inside, and the protrusion is slidably connected to the inner wall of the sliding groove. The movement of the moving block is limited by the cooperation between the protrusion and the sliding groove, so that the moving block moves along a straight line of the threaded rod.

[0010] As a preferred technical solution of this application, the two side pressure rollers abut against the side of the hub, and the positive pressure roller abuts against the top of the hub. After the two side pressure rollers and the positive pressure roller abut against the hub, the connecting block can rotate around the hub to realize the measurement of different positions of the hub.

[0011] As a preferred technical solution of this application, a measuring component is provided on the front of each of the left and right movable blocks. The measuring component includes a limiting block fixedly installed on the front of the two movable blocks. A housing is fixedly connected to the opposite side of the left and right limiting blocks. A measuring plate is slidably connected inside the limiting block and the housing. A pin is fixedly connected to the side of the measuring plate near the wheel hub. A pointer is fixedly connected to the front of the left and right limiting blocks.

[0012] As a preferred technical solution of this application, a limiting groove is formed inside the limiting block, and the width of the limiting groove is equal to the width of the measuring plate, so that the measuring plate slides in a straight line along the limiting groove, preventing the measuring plate from deviating and shaking, and improving the measurement accuracy.

[0013] As a preferred technical solution of this application, the front of the two limiting blocks on the left and right is made of transparent material, and the surface of the measuring plate is provided with a scale groove. After the pin contacts the surface of the wheel hub, the wear of the wheel hub is measured by the pointer cooperating with the scale groove on the surface of the measuring plate.

[0014] As a preferred technical solution of this application, a buffer assembly is provided inside the housing, the buffer assembly including a spring fixedly installed on the inner wall of the housing, and a damping rod is installed on the inner side of the spring.

[0015] As a preferred technical solution of this application, one end of the spring is fixedly installed on the inner wall of the housing, and the other end is fixedly connected to the measuring plate. The spring provides a thrust to the measuring plate, so that the pin abuts against the surface of the hub, which facilitates the measurement of the wear of the hub. The damping rod absorbs the elastic deformation generated by the spring, avoids the measuring plate from shaking, and improves the measurement stability of the measuring plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are: By setting a fastening assembly, two side pressure rollers and a positive pressure roller are respectively abutted against the outside of the wheel hub to be measured, thus fixing the connecting block. At this time, the connecting block can be pushed to rotate around the wheel hub, allowing wear measurement at different positions of the wheel hub. It is convenient to use and highly flexible. Through the measuring assembly, when measuring wheel hub wear, the spring will push the measuring plate to drive the pin to abut against the side wall of the wheel hub. With the help of the pointer and the scale groove opened in the measuring plate, the wear of the wheel hub is measured and compared with the original data of the wheel hub, so as to determine the wear of the wheel hub tread. The measurement is convenient. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] This utility model provides a structure for measuring the wear of train wheels, such as... Figures 1-4 As shown, the train wheel wear measurement structure includes a wheel hub 1, and a fastening assembly is provided on the outside of the wheel hub 1.

[0021] The fastening assembly includes a connecting block 2 installed on the upper outer side of the hub 1. Threaded rods 3 are fixedly installed on both the left and right ends of the connecting block 2. Moving blocks 4 are slidably connected to the outer side of threaded rods 3. Fastening nuts 5 are threadedly connected to the outer side of threaded rods 3 on the opposite side of the left and right fastening nuts 5. Brackets 6 are fixedly connected to the adjacent lower ends of the left and right moving blocks 4 respectively. Side pressure rollers 7 are rotatably connected inside brackets 6. Threaded rods 8 are threadedly connected inside the connecting block 2. A knob 9 is fixedly connected to the top of threaded rods 8. A positive pressure roller 10 is rotatably connected to the bottom of threaded rods 8. The measuring assembly is installed on the hub 1 through the positive pressure roller 10 and the side pressure roller 7. At the same time, the rotation of the measuring assembly can be realized by the positive pressure roller 10 and the side pressure roller 7.

[0022] The threaded rod 3 has grooves on both the front and rear sides of its outer surface. The upper end of the movable block 4 has a protrusion inside, and the protrusion is slidably connected to the inner wall of the groove. The protrusion and the groove cooperate to limit the movement of the movable block 4, so that the movable block 4 moves linearly along the threaded rod 3.

[0023] The two side pressure rollers 7 on the left and right sides abut against the side of the hub 1, and the positive pressure roller 10 abuts against the top of the hub 1. After the two side pressure rollers 7 and the positive pressure roller 10 abut against the hub 1, the connecting block 2 can rotate around the hub 1 to realize the measurement of different positions of the hub 1.

[0024] Specifically, two side pressure rollers 7 and a positive pressure roller 10 are installed on the outside of the hub 1 to be measured. Then, the two moving blocks 4 are pushed to move in a straight line along the threaded rod 3 until the side pressure rollers 7 abut against the sides of the hub 1. Then, the fastening nut 5 is rotated to connect with the threaded rod 3, so that the fastening nut 5 fixes the moving block 4. Then, the knob 9 is rotated to drive the threaded rod 8 to rotate and connect with the connecting block 2, so that the positive pressure roller 10 moves down to abut against the top of the hub 1, thereby fixing the connecting block 2. At the same time, the connecting block 2 can be pushed to rotate around the hub 1, so that wear can be measured at different positions of the hub 1.

[0025] like Figures 2-3 As shown, measuring components are respectively provided on the front of the left and right movable blocks 4. The measuring components include limiting blocks 11 fixedly installed on the front of the two movable blocks 4. A housing 12 is fixedly connected to the opposite side of the left and right limiting blocks 11. A measuring plate 13 is slidably connected inside the limiting blocks 11 and the housing 12. A pin 14 is fixedly connected to the side of the measuring plate 13 near the hub 1. A pointer 15 is fixedly connected to the front of the left and right limiting blocks 11.

[0026] The limiting block 11 has a limiting groove inside, and the width of the limiting groove is equal to the width of the measuring plate 13, so that the measuring plate 13 slides in a straight line along the limiting groove, preventing the measuring plate 13 from deviating or shaking, and improving the measurement accuracy.

[0027] The front of the two limit blocks 11 on the left and right is made of transparent material. The measuring plate 13 has a scale groove on its surface. After the pin 14 contacts the surface of the wheel hub 1, the wear of the wheel hub 1 is measured by the pointer 15 cooperating with the scale groove on the surface of the measuring plate 13.

[0028] like Figure 5 As shown, a buffer assembly is provided inside the housing 12. The buffer assembly includes a spring 16 fixedly installed on the inner wall of the housing 12. A damping rod 17 is installed inside the spring 16. The damping rod 17 absorbs the elastic deformation generated by the spring 16 and prevents the measuring plate 13 from shaking.

[0029] One end of the spring 16 is fixedly installed on the inner wall of the housing 12, and the other end is fixedly connected to the measuring plate 13. The spring 16 provides a thrust to the measuring plate 13, so that the pin 14 abuts against the surface of the hub 1, which facilitates the measurement of the wear of the hub 1. The damping rod 17 absorbs the elastic deformation generated by the spring 16, avoids the measuring plate 13 from shaking, and improves the measurement stability of the measuring plate 13.

[0030] Specifically, when measuring the wear of the wheel hub 1, the spring 16 will push the measuring plate 13 to drive the pin 14 to abut against the side wall of the wheel hub 1. With the help of the pointer 15 and the scale groove opened on the measuring plate 13, the wear of the wheel hub 1 is measured and compared with the original data of the wheel hub 1 to determine the wear of the wheel hub 1 tread.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
