[0002] With the research and production of new steel, the first steel rolling plant plate production line uses more and more ultra-fast cooling systems to cool the rolled steel plate quickly to obtain better and more stable steel, and enhance the competitiveness and benefits of Liuzhou Steel in the market.

[0003] But when using ultra-fast cooling, due to the combined influence of multiple rapid change factors such as adjusted water quantity and water ratio, changed rolling temperature, cooling water temperature, and fast cooling speed, a large number of buckling plates are more likely to be produced; finally, a thick plate straightening machine is used to straighten the buckling plate as a rescue measure. The original thick straightening machine has only one stopper on the north-south roll gap position, and there is no numerical value display; and due to frequent use, the north-south stress is uneven, causing the roll gap to change inconsistently, and the straightened steel plate often presents abnormal north-south flatness, which does not achieve the purpose of straightening, causing waste of manpower and resources. At this time, a sensor is needed to replace the stopper to collect roll gap change data, but the sensor is easily affected by the external environment when in use, and there is currently a lack of a fixing device for placing and protecting the sensor on the market.

[0026] In order to make the above objects, features and advantages of the present application more apparent, a detailed description of the specific embodiments of the present application will be given below with reference to the accompanying drawings.

[0027] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited by the specific embodiments disclosed below.

[0028] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. In this specification, "in one embodiment" does not mean the same embodiment, nor does it mean an embodiment that is separate from or mutually exclusive of other embodiments.

[0029] Embodiment 1

[0030] Referring to Figs. 1-3 For the first embodiment of the present application, the embodiment provides a placing mechanism, which comprises a first accommodating shell 101, a magnetic ring 102 sleeved on the outer wall of the first accommodating shell 101, a magnetic ring fixing seat 103 sleeved on the outer wall of the magnetic ring 102, and a pressing limiting rod 104 fixedly connected to the end of the magnetic ring fixing seat 103 away from the first accommodating shell 101.

[0031] The first accommodating shell 101 is a long rod, and one end of the long rod of the first accommodating shell 101 is provided with a stepped structure. The first accommodating shell 101 has a space for accommodating the displacement sensor, so that the displacement sensor is used to achieve the working purpose. The thickness and material of the first accommodating shell 101 have little effect on the working of the displacement sensor. When the displacement sensor is directly exposed without being wrapped by the first accommodating shell 101, the accuracy of the displacement sensor will decrease due to the influence of external humidity and temperature. Therefore, wrapping the displacement sensor with the first accommodating shell 101 can reduce the degree of influence of the external environment on the accuracy. The ring hole in the middle of the magnetic ring 102 is penetrated by the long rod part of the first accommodating shell 101. The magnetic ring fixing seat 103 wraps the magnetic ring 102. The magnetic ring fixing seat 103 is a hollow cylinder, and through holes are formed on two non-arc surfaces. The through hole on the magnetic ring fixing seat 103 close to the first accommodating shell 101 can accommodate the long rod part of the first accommodating shell 101. The through hole on the magnetic ring fixing seat 103 away from the first accommodating shell 101 can accommodate the pressing limiting rod 104. The magnetic ring 102 is fixed in the magnetic ring fixing seat 103 and slides on the long rod part of the first accommodating shell 101. The pressing limiting rod 104 is fixedly connected to the magnetic ring fixing seat 103 away from the first accommodating shell 101.

[0032] In use, the displacement sensor is placed in the first accommodating shell 101, and the placing mechanism 100 is placed in the working position. The buckling plate enters the predetermined position, and the buckling part of the buckling plate contacts the end of the pressing limiting rod 104 away from the first accommodating shell 101, so that the height of the pressing limiting rod 104 changes. When the height of the pressing limiting rod 104 changes, the magnetic ring fixing seat 103 fixedly connected to the pressing limiting rod 104 is driven to change. When the magnetic ring fixing seat 103 is driven to change, the magnetic ring 102 fixed in the magnetic ring fixing seat 103 slides on the long rod part of the first accommodating shell 101. When the magnetic ring 102 is driven to slide, the magnetic ring 102 slides up and down on the long rod part of the first accommodating shell 101. The displacement sensor in the first accommodating shell 101 receives the signals of the rising and falling of the magnetic ring 102. The buckling on the surface of the buckling plate is converted into the position change of the magnetic ring 102 through the pressing limiting rod 104 and the magnetic ring fixing seat 103, and then transmitted to other components through wired connection or wireless transmission for processing and display of the specific value of the roll gap.

[0033] In summary, in the use process of the utility model, the displacement sensor is placed in the first accommodating shell 101, and the degree of buckling and recovery of the buckling plate cannot be confirmed by the limit stopper, compared with the use of the limit stopper, the collection accuracy is improved, the placement and position fixing of the displacement sensor for collecting the data of the buckling and recovery of the buckling plate and the change of the north-south roll gap can be realized, the position change of the magnetic ring 102 driven by the pressing limit rod 104 is received by the displacement sensor, and the placement mechanism 100 can reduce the degree of influence of other factors on the displacement sensor except the movement of the magnetic ring.
