Description

Technical Field

[0001] This utility model relates to the field of mechanical measuring tools, and in particular to a tool for rapid detection of the outer diameter of a roller. Background Technology

[0002] Currently, many steel mills use multi-segment free roll structures in the sector section of continuous casting machines. Multi-segment free rolls have strong load-bearing capacity and are not easily bent or deformed after long-term operation, which can provide good support for the billet and improve the quality of the billet. However, this type of roll system results in a large number of multi-segment free rolls, making it difficult to align the arcs, and requiring high precision in the outer diameter of the free rolls. That is, the outer diameter of the segmented rolls in the same group of rolls cannot deviate too much, otherwise it is easy to cause misalignment and water leakage of the segmented rolls.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be further described in detail below with reference to specific examples and accompanying drawings.

[0024] Example 1

[0025] Please see Figure 1 The diagram illustrates the structure of a rapid roller outer diameter detection tool according to an embodiment of the present invention, including: a bridging member 10; and two measuring arms 20 fixed at both ends of the bridging member 10; wherein the two measuring arms 20 are arranged in parallel relative to each other and the measuring distance is greater than or equal to the diameter of the target roller and less than or equal to the diameter of the target roller plus the maximum error value, and the measuring depth of the two measuring arms 20 is greater than the radius of the target roller.

[0026] Specifically, the detection tool in this embodiment needs to be designed according to the diameter of the target roller and its maximum allowable error value. During use, the corresponding detection tool needs to be selected based on the target roller. More specifically, during use, the detection tool of this embodiment is inserted radially from any position on the target roller. If the detection tool can pass through the diameter of the target roller, it indicates that the target roller is excessively worn; otherwise, it indicates that the target roller is normal.

[0027] In an optional implementation, to ensure the accuracy of the detection, multiple measurement points need to be selected on the target roller and measured sequentially using the detection tool in this embodiment.

[0028] Example 2

[0029] In one embodiment, such as Figure 2 As shown in the schematic diagram, a rapid roller outer diameter detection tool according to this embodiment includes: a bridging member 10; and two measuring arms 20 fixed at both ends of the bridging member 10. The two measuring arms 20 are arranged parallel to each other, with a measuring distance greater than or equal to the diameter of the target roller and less than or equal to the diameter of the target roller plus the maximum error value. The measuring depth of the two measuring arms 20 is greater than the radius of the target roller. Unlike Embodiment 1, both measuring arms are trapezoidal and arranged with their narrow faces facing each other. This narrow-face arrangement helps to observe the contact between the contact surface and the target roller to determine whether the detection tool passes through the diameter of the target roller. The other structural parts of this embodiment are the same as in Embodiment 1.

[0030] Specifically, the detection tool in this embodiment needs to be designed according to the diameter of the target roller and its maximum allowable error value. During use, the corresponding detection tool needs to be selected based on the target roller. More specifically, during use, the detection tool of this embodiment is inserted radially from any position on the target roller. If the detection tool can pass through the diameter of the target roller, it indicates that the target roller is excessively worn; otherwise, it indicates that the target roller is normal.

[0031] In an optional implementation, to ensure the accuracy of the detection, multiple measurement points need to be selected on the target roller and measured sequentially using the detection tool in this embodiment.

[0032] Example 3

[0033] In one embodiment, such as Figure 3 As shown in the schematic diagram, a rapid roller outer diameter detection tool according to this embodiment includes: a bridging member 10; and two measuring arms 20 fixed at both ends of the bridging member 10. The two measuring arms 20 are arranged parallel to each other, with a measuring distance greater than or equal to the diameter of the target roller and less than or equal to the diameter of the target roller plus a maximum error value. The measuring depth of the two measuring arms 20 is greater than the radius of the target roller. Unlike Embodiment 1, both measuring arms have scales 21 on their sides. The scales in this embodiment help determine the measuring depth at the contact point between the contact surface and the target roller to determine whether the detection tool has passed through the diameter of the target roller. The other structural components of this embodiment are the same as in Embodiment 1.

[0034] Specifically, the detection tool in this embodiment needs to be designed according to the diameter of the target roller and its maximum allowable error value. During use, the corresponding detection tool needs to be selected based on the target roller. More specifically, during use, the detection tool of this embodiment is inserted radially from any position on the target roller. If the detection tool can pass through the diameter of the target roller, it indicates that the target roller is excessively worn; otherwise, it indicates that the target roller is normal.

[0035] In an optional implementation, to ensure the accuracy of the detection, multiple measurement points need to be selected on the target roller and measured sequentially using the detection tool in this embodiment.

[0036] Example 4

[0037] In one embodiment, see Figure 4This embodiment illustrates the structure of a rapid roller outer diameter detection tool, including: a bridging member 10; two measuring arms 20 fixed at both ends of the bridging member 10; a probe 30, which is elastic and has a length greater than the radius of the target roller; and a magnetic base 40, one end of which has an insertion hole and the other end is a magnetic suction plane. The probe 30 is detachably connected to the magnetic base 40 through the insertion hole 41, and the magnetic base 40 is movable and detachably magnetically attached to either measuring arm 20. The two measuring arms 20 are arranged parallel to each other, and the measurement distance is greater than or equal to the diameter of the target roller and less than or equal to the diameter of the target roller plus the maximum error value. Specifically, during use, the magnetic base 40 is magnetically attached to either measuring arm 20, and the depth of the probe 30 to the free end of the measuring arm 20 is greater than the radius of the target roller. The user then observes whether the top of the target roller touches the probe 30 to determine if the detection tool has passed through the diameter of the target roller. Furthermore, the user needs to select the appropriate detection tool based on the target roller during use. More specifically, during use, the detection tool of this embodiment is inserted radially from any position on the target roller. If the detection tool can pass through the diameter of the target roller, it indicates that the target roller is worn too much; otherwise, it indicates that the target roller is normal.

[0038] In an optional implementation, to ensure the accuracy of the detection, multiple measurement points need to be selected on the target roller and measured sequentially using the detection tool in this embodiment.

[0040] Based on any of the embodiments 1-4, the measuring contact surfaces of the two measuring arms 20 of this utility model are provided with a wear-resistant layer. The wear-resistant layer includes a metal plating layer or a quenched layer, wherein the metal plating layer includes a copper or chromium plating layer. The metal plating layer not only improves the wear resistance of the contact surface but also assists in observing the wear condition of the metal plating layer to determine whether the testing tool can continue to be used.

[0042] like Figure 5 As shown, based on any of Embodiments 1-5, the difference between this embodiment and Embodiments 1-5 is that the roller outer diameter rapid detection tool further includes: a diameter variable block 50, which is detachably disposed on the measuring contact surface of the two measuring arms. In this embodiment, the diameter variable block 50 can change the measuring distance, thereby adapting to different roller objects.

[0043] In one alternative embodiment, the reducing block 50 is a magnetic block that can be positioned at any location on the contact surface of the measuring arm 20.

[0044] In one alternative embodiment, a connector is provided on one side of the reducing block 50, and a slot is provided on the corresponding contact surface of the measuring arm 20. The reducing block 50 is detachably connected to the measuring arm 20 via the connector.
