[0002] In the process of measuring train wheel axles and wheelsets, the axles need to be moved to measure parameters at multiple points. Traditional methods typically rely on multiple lifting and lowering operations using a lifting device. However, this method is not only complex and inefficient, but the frequent lifting also poses significant safety risks. Therefore, a new auxiliary device is needed that can quickly and accurately locate train wheel axles, facilitate axle position adjustments, simplify the operation process, and improve measurement efficiency.

[0003] To address the problems of high complexity, low efficiency, and high risk in existing train wheel axle and wheelset measurement methods, this invention proposes an auxiliary device for train wheel axle and wheelset measurement. The core objectives of this device are: to achieve rapid and accurate positioning of train wheel axle and wheelsets; to significantly improve measurement efficiency by reducing the number of lifting operations and simplifying the process; and to ensure the accuracy and safety of the measurement.

Detailed Implementation

[0023] 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.

[0024] Example 1

[0025] Combination Figures 1-6 A train wheel axle wheelset measurement auxiliary device includes a base assembly 1, a lifting assembly 2, and an alignment assembly 3.

[0026] See Figure 4 and Figure 5 Furthermore, the base assembly 1 includes a base 5, a lifting assembly mounting plate 6, and a centering assembly mounting plate 7. The lifting assembly mounting plate 6 is fixedly installed at the inner center of the base 5, and the centering assembly mounting plate 7 is fixedly installed on the upper part of the base 5, located on the outer side of the lifting assembly mounting plate 6.

[0027] Specifically, the base assembly 1 is used to place the guide rod 9 to ensure the vertical lifting and lowering of the centering assembly 3. The bottom is designed with a lifting assembly mounting plate 6 for the installation and positioning of the lifting assembly 2.

[0028] Example 2

[0029] See Figure 2 Furthermore, based on Embodiment 1, the lifting assembly 2 includes a jack 8, four guide rods 9, and a positioning block mounting plate 10. The jack 8 is fixedly installed on the upper part of the lifting assembly mounting plate 6, the four guide rods 9 are fixedly installed on the upper part of the centering assembly mounting plate 7 near the middle position, and the positioning block mounting plate 10 is slidably disposed between the four guide rods 9.

[0030] Specifically, the lifting assembly 2 consists of a mechanical jack 8, a guide rod 9, and a positioning block mounting plate 10. The mechanical jack 8 has a simple structure, few parts, low manufacturing and maintenance costs, and can stably support heavy objects for a long time.

[0031] Example 3

[0032] See Figure 3Furthermore, based on Embodiment 1 and Embodiment 2, the centering component 3 includes a support roller 11, a positioning block 12, and a bearing 13. The positioning block 12 is fixedly installed on the upper part of the positioning block mounting plate 10. The two ends of the support roller 11 are rotatably installed on the inner side of the positioning block 12 through the bearing 13. The center position of the positioning block 12 is V-shaped, and two sets of bearings 13 are symmetrically arranged. A through hole is opened at the center position of the centering component mounting plate 7. The output shaft of the jack 8 passes through the through hole and is fixedly connected to the positioning block mounting plate 10. A rotating shaft is rotatably installed on the positioning block mounting plate 10 and is fixedly connected to the positioning block mounting plate 10.

[0033] Specifically, the positioning block 12 achieves vertical lifting and lowering through the guide rod 9 and the jack 8, and achieves automatic fine-tuning centering through the bottom rotating shaft. The support roller 11 is tangent to the axle of the train wheel axle wheel pair 4, and the axle can rotate freely to adjust its posture.

[0034] It should be noted that this utility model is a train wheel axle wheelset measuring auxiliary device. In use, the two measuring auxiliary devices are placed horizontally and aligned. The jack 8 is adjusted to the lowest position. The train wheel axle wheelset 4 is placed on the two measuring auxiliary devices using a crane or other lifting equipment. The train wheel axle wheelset 4 is adjusted to be horizontal by the jack 8. During this process, if the train wheel axle wheelset 4 is slightly tilted, it can be automatically aligned by rotating the centering component. Since the positioning block 12 is rotatably connected to the positioning block mounting plate 10, the positioning block 12 can automatically fine-tune the centering through the rotating shaft.

[0035] Once the train wheel axle wheelset 4 is placed stably, the lifting device can be removed, and the measurement can begin.

[0036] In summary, the train wheel axle wheelset measurement auxiliary device proposed in this utility model, through its unique design and technical solution, achieves precise positioning, secure fixing, and efficient measurement of train wheel axle wheelsets.
