Description

Technical Field

[0001] This utility model relates to the field of measuring tool technology, and in particular to a template for measuring the gap position of a post-rolled rail cooling device. Background Technology

[0002] In the production process of rolled steel rails, heat-treated rails require rapid cooling after rolling using a cooling device to achieve an ideal microstructure, thereby improving strength and hardness. The gap position of the cooling device is crucial to the cooling effect, as it directly affects the contact area and cooling intensity between the cooling medium and the rail surface. If the gap is too large or too small, it will lead to uneven cooling, resulting in localized overcooling or undercooling, which seriously affects the microstructure and properties of the rail.

[0003] In actual production, to ensure consistent cooling performance, the distance between the cooling device and the rail must be adjusted to meet requirements. Currently, this is typically done manually using tools such as steel rulers and calipers to directly measure the gap. However, this method is limited by workspace constraints, often resulting in a narrow operating area and causing numerous inconveniences. Furthermore, human factors have a significant impact; differences in operating habits and skill levels among operators can lead to inaccurate measurement results. Additionally, this method is time-consuming, labor-intensive, and inefficient, failing to meet the demands of high-efficiency production. Utility Model Content

The three measuring parts are respectively disposed on the three contact surfaces of the template body away from the post-rolled rail, and each measuring part includes a first measuring point and a second measuring point. The first measuring point is the maximum gap between the cooling device and the post-rolled rail that meets the cooling requirements, and the second measuring point is the minimum gap between the cooling device and the post-rolled rail that meets the cooling requirements. An observation window is provided between the first measuring point and the second measuring point to observe whether the cooling end face of the cooling device is located within the observation window.

[0020] 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.

[0021] The purpose of this invention is to provide a template for measuring the gap position of a post-rolled rail cooling device, in order to solve the problems existing in the prior art. It has a simple structure, is easy to use, effectively ensures the accuracy of the gap position measurement of the cooling device, and improves work efficiency.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] This utility model provides a template for measuring the gap position of the cooling device 11 after rolling of steel rail 9, such as... Figures 1-2 As shown, the device includes a template body 1 and three measuring parts. The template body 1 is provided with a snap-fit ​​groove for snap-fitting and positioning with the rolled rail 9. The three measuring parts are respectively located on the three contact surfaces of the template body 1 away from the rolled rail 9. Each measuring part includes a first measuring point 6 and a second measuring point 7. The first measuring point 6 is the maximum gap between the cooling device 11 and the rolled rail 9 that meets the cooling requirements. The second measuring point 7 is the minimum gap between the cooling device 11 and the rolled rail 9 that meets the cooling requirements. An observation window 10 is located between the first measuring point 6 and the second measuring point 7 to observe whether the cooling end face of the cooling device 11 is located within the observation window 10. By clearly setting the first measuring point 6 and the second measuring point 7, and using the area between them as the observation window 10, the operator can intuitively determine whether the gap between the cooling device 11 and the rolled rail 9 is within the range that meets the cooling requirements by observing whether the cooling end face of the cooling device 11 is within the observation window 10. This simplifies the measurement and judgment process and improves measurement efficiency and accuracy.

[0024] In a preferred embodiment, the three measuring parts include a protrusion 4 and a groove 5. The protrusion 4 is integrally connected to the template body 1, and the end of the protrusion 4 away from the template body 1 is the first measuring point 6. The groove 5 is located on the side of the template body 1 away from the rolled rail 9, and the bottom surface of the groove 5 is the second measuring point 7. The design of using protrusion 4 and groove 5 to form the measuring parts and integrally connecting them results in a simple and stable structure. The end of the protrusion 4 serves as the first measuring point 6 with the largest gap, and the bottom surface of the groove 5 serves as the second measuring point 7 with the smallest gap. This intuitive physical structure can more accurately define the gap range, and the integral connection enhances the overall strength of the measuring parts and the template body 1, reduces measurement errors caused by loose parts, and improves measurement accuracy.

[0025] In a preferred embodiment, the side of the protrusion 4 near the groove 5 is coplanar with the side of the groove 5 near the protrusion 4. The coplanarity of the sides of the protrusion 4 and the groove 5 near each other ensures the planar consistency of the observation window 10. This prevents visual errors caused by non-coplanarity of the sides when the operator observes the cooling end face of the cooling device 11, further improving the accuracy of judgment. At the same time, this coplanar arrangement also helps to improve the overall aesthetics and structural compactness of the template.

[0026] In a preferred embodiment, the template body 1 includes an integrally connected horizontal plate 2 and two side plates 3. The two side plates 3 are disposed at both ends of the horizontal plate 2 to form the snap-fit ​​groove between the two side plates 3. A measuring part is disposed on the side of the horizontal plate 2 away from the rolled rail 9, and a measuring part is disposed on the side plate 3 away from the rolled rail 9. This structural design not only makes the snap-fit ​​groove structure more reasonable and can firmly snap the rolled rail 9, but also allows for the measurement and judgment of the gap between the cooling device 11 and the rail from multiple angles by reasonably distributing the measuring parts on the horizontal plate 2 and the side plates 3. This improves the comprehensiveness and accuracy of the measurement, and can more accurately reflect the gap between the cooling device 11 and the rail, providing more reliable data support for the control of the cooling effect.

[0027] In a preferred embodiment, the horizontal plate 2 contacts the top surface of the rolled rail 9, and the side plate 3 contacts the side surface of the rolled rail 9. The method of the horizontal plate 2 contacting the top surface of the rolled rail 9 and the side plate 3 contacting the side surface allows the template to fully fit with the rolled rail 9, ensuring the stability of the clamping. At the same time, it enables the measuring part to accurately correspond to the gap between the cooling device 11 and the rail at different positions, ensuring accurate gap measurement information is obtained from the two key positions of the top surface and the side surface, and improving the reliability of the measurement results.

[0028] In a preferred embodiment, two circular grooves are also included. These grooves are located at the connection point between the side plate 3 and the cross plate 2 within the snap-fit ​​groove. The circular grooves can reduce the weight of the template to some extent, which is beneficial to the convenience of operation. At the same time, the circular grooves can also play a role in stress dispersion, avoiding damage to the template due to local stress concentration during the snap-fit ​​process, and extending the service life of the template.

[0029] In a preferred embodiment, the sample body 1 is a metal structure. Metal structures possess high strength and hardness, ensuring that the sample will not deform under external forces during frequent use, thus guaranteeing measurement accuracy. Metal structures also exhibit good wear resistance, extending the sample's lifespan and reducing measurement costs.

[0030] In a preferred embodiment, all corners of the template body 1 are rounded, which prevents the corners from scratching operators or other equipment during operation. Furthermore, the rounded transitions enhance the overall aesthetics of the template, and compared to sharp corners, they also improve the structural strength and stability of the template to some extent.

[0031] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
