DETAILED DESCRIPTION
[0024] The utility model is described in detail below with reference to the accompanying drawings.
[0025] As attached Figure 1 As shown, a hot-rolled steel plate thickness measuring device according to an embodiment of the utility model comprises a trolley 4, a back plate 2, a back plate slide 8, a back plate cylinder 3, a back plate slide rail mechanism 9, an upper clamping jaw 7, a clamping jaw cylinder 6, a displacement sensor 1 and a lower clamping jaw 10.

[0026] As attached Figure 2 and attached Figure 3As shown, the utility model device is provided with structures such as a trolley 4, a back plate slide rail mechanism 9, a back plate slide 8, a back plate cylinder 3, an upper clamp 7, a lower clamp 10 and a clamp cylinder 6. When in use, the trolley 4 can be used to move the entire device to the hot-rolled steel plate 13 to be tested, so as to conveniently move the entire device; and then the connection between the back plate slide rail mechanism 9, the back plate cylinder 3 and the back plate slide 8 is used. Since the back plate slide 8 is relatively fixed to the back plate 2 and the trolley 4, the back plate slide rail mechanism 9 can be controlled by the back plate cylinder 3 as needed to move along the back plate slide rail thereon. It moves up and down, indirectly controlling the lower clamping jaw 10 fixedly connected to the back plate slide rail mechanism 9 to move until the lower clamping jaw 10 is located at the lower end of the hot-rolled steel plate 13 to be tested; at this time, the upper clamping jaw 7 can be driven by the clamping jaw cylinder 6 to move along the back plate slide rail on the back plate slide rail mechanism 9 toward the lower clamping jaw 10 until the hot-rolled steel plate 13 is clamped between the upper clamping jaw 7 and the lower clamping jaw 10, and the displacement sensor 1 can collect the path value of the movement of the upper clamping jaw 7, and combined with the original spacing between the upper clamping jaw 7 and the lower clamping jaw 10, the thickness of the hot-rolled steel plate 13 can be accurately and stably obtained.
[0027] In this embodiment, the maximum opening and closing height of the upper clamping jaw 7 and the lower clamping jaw 10 can be 170 mm. When measuring the thickness, the upper clamping jaw 7 is moved downward by the clamping jaw cylinder 6 to fully fit the upper surface of the hot-rolled steel plate 13 to be tested; the lower clamping jaw 10 is driven by the back plate cylinder 3 to drive the back plate slide rail mechanism 9 to move upward to fully fit the lower surface of the hot-rolled steel plate 13 to be tested. After the measurement is completed, the upper clamping jaw 7 and the lower clamping jaw 10 automatically return to the initial position.
[0028] In another embodiment, rollers are provided at the bottom of the trolley 4. Thus, when in use, the arrangement of the rollers facilitates the movement of the trolley 4 as required.
[0029] In another embodiment, a trolley cylinder 5 is further included, and the rear end of the trolley 4 is connected to the trolley cylinder 5, which is used to drive the trolley 4 to move forward and backward. In this way, when in use, the trolley cylinder 5 can be used to push the trolley 4 to conveniently perform further position adjustment.
[0030] The trolley slide mechanism 12 and the trolley slide 11 are also included. The lower end of the trolley 4 is connected to the trolley slide 11. The lower end of the trolley slide 11 is slidably arranged on the trolley slide mechanism 12. The trolley cylinder 5 is used to drive the trolley 4 to move forward and backward on the trolley slide mechanism 12. In this way, in this embodiment, the trolley slide mechanism 12 and the trolley slide 11 can be used to limit the moving path of the trolley 4, thereby ensuring the stability of the movement of the trolley 4. At the same time, during the detection, the trolley slide mechanism 12 as a base can also provide the stability of the detection to a certain extent.
[0031] Wherein, the bottom of the trolley slide rail mechanism 12 is provided with a lockable roller. With this, when in use, the trolley slide rail mechanism 12 as the base can be moved conveniently.
[0032] The photoelectric position switch is also included, which is installed at the front end of the trolley 4 and is electrically connected to the trolley cylinder 5. In this way, when the trolley 4 moves to the desired position, the photoelectric position switch detects the position information and controls the trolley cylinder 5 to stop driving the trolley 4 to move.
[0033] In another embodiment, the displacement sensor 1 is a grating displacement sensor, so as to ensure the accuracy of the detection data.
[0034] In another embodiment, a PLC is further included, and the back plate cylinder 3, the clamping jaw cylinder 6 and the displacement sensor 1 are electrically connected to the PLC respectively, and the PLC is used to control the start and stop of the back plate cylinder 3 and the clamping jaw cylinder 6, and the PLC is used to receive the displacement data of the upper clamping jaw 7 obtained by the displacement sensor 1. In this way, the control convenience of the device is increased.
[0035] The upper computer is also included, and the PLC is electrically connected to the upper computer, and the upper computer is used to receive the signal of the PLC and display the displacement data of the upper clamping jaw 7. In this way, the collected data can be confirmed.
[0036] In another embodiment, a protective cover is provided on the displacement sensor 1. In this way, the displacement sensor 1 can be protected to a certain extent, thereby increasing the service life of the displacement sensor 1. In this embodiment, other components can also be provided with protective covers as needed.
[0037] When the device of the utility model is in use, the displacement sensor 1 or other components can be cooled by direct blowing through an air pipe as required.
[0038] The utility model device can make the whole measuring process fully automatic, and the measurement is fast and the data is accurate. Compared with the existing ray measurement technology in high temperature environment, the cost is low and the accuracy is high. The device has a simple structure and low maintenance cost, and can improve the on-site working environment of rolling personnel, thereby improving production efficiency and product yield rate.
[0039] In another specific embodiment, the device of the utility model can also be installed on both sides of the roller gap after the main rolling mill and before the leveling machine when in use. The main rolling mill makes the slab into a titanium plate. After rolling is completed and the slab stops at a suitable position on the roller, a measurement instruction is sent to the thickness measuring device. The trolley cylinder 5 pushes the measuring device into the titanium plate, and the back plate cylinder 3 pushes the back plate slide mechanism 9 to move upward, so that the lower clamping jaw 11 contacts the lower surface of the plate. Then the clamping jaw cylinder 6 is operated, and the upper clamping jaw 7 contacts the upper surface of the plate. The physical quantity moved by the upper clamping jaw 7 is calculated by PLC to obtain the measured thickness of the plate and sent to the upper computer screen for display. After the measurement is completed, the upper clamping jaw 7 is released, and the trolley 4 drives the measuring device back to its original position. The measured value is maintained until the next measurement begins. The entire measurement process is automatically measured through PLC, and a single measurement takes only 10 seconds.
[0040] The utility model has simple structure, convenient maintenance, low equipment investment, high degree of automation, and eliminates the hard work of workers to measure manually at high temperature. The measurement accuracy is high, and the error is less than 0.05 mm.

Changes or adjustments in their relative relationships should be regarded as the scope of implementation of the utility model without substantially changing the technical content.
[0042] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should be regarded as the protection scope of the utility model.
