Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] refer to Figure 1 and Figure 3 A hot-rolled steel plate thickness measuring device is provided. The placement box 1 is used to place the steel plate after the thickness test is completed, so that the steel plate does not need to be manually moved to a more distant storage location, which saves time and effort. The top of the placement box 1 is provided with a measuring chamber 5, which is used to accommodate the components for measuring the thickness. At the same time, the measuring chamber 5 is used to support components such as the touch host 11.

[0032] refer to Figure 2 and Figure 5 The connecting mechanism 12 is located inside the measuring chamber 5. The connecting mechanism 12 is used to connect and fix components such as the drive mechanism 13. The connecting mechanism 12 is fixedly connected to the top of the placement box 1 by bolts, so that the connecting mechanism 12 can be easily disassembled by removing the screws. A support platform 24 is provided on one side of the front of the connecting mechanism 12. The support platform 24 is used to support the steel plate to be measured. A pressure plate 22 is provided at the top of the support platform 24 for telescopic adjustment of the width between the support platform 24 and the plate, so that steel plates of different thicknesses can be placed.

[0033] refer to Figure 2 and Figure 5A laser rangefinder 23 is fixedly connected to the lower pressure plate 22. The laser rangefinder 23 measures the distance by measuring the time from the start of laser emission to the laser being reflected back from the target. A touch host 11 is provided at the top of the measuring chamber 5. The touch host 11 is an integrated unit of touch screen and host, integrating the host and display parts together. The laser rangefinder 23 is connected to the touch host 11 via Bluetooth signal or data cable, so that the measured data can be transmitted to the CNC screen for recording in real time.

[0034] refer to Figure 3 The placement plate 14 is located inside the placement box 1. The placement plate 14 is used to place the steel plate after the distance measurement is completed. There are multiple placement plates 14, which can hold multiple steel plates at the same time. The front of the placement plate 14 is provided with a labeling slot 15. The labeling slot 15 is used to affix the corresponding serial number label, so that it can correspond to the data recorded by the touch host 11. The labeling slot 15 is embedded inside the placement plate 14, so that the label affixed in the labeling slot 15 is more secure.

[0035] refer to Figures 1-5 The distance is measured using a laser rangefinder 23. The measured data is stored in the touchscreen host 11. Simultaneously, steel plates are placed according to their corresponding numbers inside the designated placement plates 14, and labels for the serial numbers are affixed to the labeling slots 15. This allows for the safe storage of the measured steel plates, eliminating the need for manual relocation. Furthermore, the thickness of the tested steel plates can be recorded, preventing data loss due to mixing with unmeasured plates.

[0036] refer to Figure 1 The bottom of the placement box 1 is fixedly connected to four corners of a support frame 2. The support frame 2 is used to support the placement box 1. The support frame 2 is telescopic, so when the equipment needs to be moved, the support frame 2 can be retracted and the equipment can be moved by casters 3. Casters 3 are provided on the inner side of the support frame 2. The casters 3 are rotatably connected to the bottom of the placement box 1. The equipment can be moved easily by the casters 3, so that the steel plate inside the placement box 1 does not need to be manually moved. The steel plate can be removed after the entire equipment is moved, which is more labor-saving.

[0037] refer to Figure 1 and Figure 4 The placement box 1 has a front door 4 on the front, which is rotatably connected to the placement box 1 by a hinge. The front door 4 can be opened by rotating it, so that the steel plate to be measured can be placed inside the placement box 1. The placement box 1 has a back door 17 on the back, which is rotatably connected to the placement box 1 by a hinge. So both the front and back of the placement box 1 can be opened. It can be used in environments where the front door 4 or the back door 17 cannot be opened. The placement box 1 can also be opened normally in some narrow environments.

[0038] refer toFigure 1 Handles 6 are fixedly connected to both sides of the front of the placement chamber. The handles 6 are used to make it easy for personnel to pick up the measurement chamber 5 when disassembling it. The measurement chamber 5 is connected to the placement box 1 by screws. Therefore, when it is necessary to disassemble the measurement chamber 5, the screws can be removed directly. After disassembling the measurement chamber 5 and the upper components, a new placement box 1 can be placed to test other steel plates, which is quite convenient.

[0039] refer to Figure 1 A power switch 7 is located on one side of the top front of the device. The power switch 7 is turned on by inserting a key to prevent accidental activation. A power light 8 is located next to the power switch 7. The power light 8 will light up when the device is started. A fault light 9 is located next to the power light 8. The fault light 9 will light up when the device malfunctions. A stop switch 10 is located next to the fault light 9. The device can be shut down in an emergency by turning the stop switch 10. The power light 8, power switch 7, power light 8 and stop switch 10 are spaced evenly to prevent accidental activation. The power light 8, power switch 7, power light 8 and stop switch 10 are electrically connected to the touch control host 11 via wires.

[0040] refer to Figure 5 A drive mechanism 13 is fixedly connected to one side of the front of the connecting mechanism 12. The drive mechanism 13 is used to drive the first telescopic rod 18 to extend and retract. An air pump 16 is fixedly connected to one side of the back of the connecting mechanism 12. The air pump 16 is used to enable the drive mechanism 13 to complete the function of driving the first telescopic rod 18 to extend and retract. The first telescopic rod 18 is slidably connected to the bottom end of the drive mechanism 13. The bottom end of the first telescopic rod 18 is fixedly connected to the lower pressure plate 22. The extension and retraction of the first telescopic rod 18 synchronously drives the lower pressure plate 22 to rise and fall, so that steel plates of different thicknesses can be used.

[0041] refer to Figure 5 The drive mechanism 13 has a second telescopic rod 19 on both sides. The bottom end of the second telescopic rod 19 is fixedly connected to the lower pressure plate 22. The second telescopic rod 19 passes through the connecting mechanism 12 and is slidably connected to the connecting mechanism 12. When the first telescopic rod 18 extends and retracts, it drives the second telescopic rod 19 to extend and retract synchronously. The second telescopic rod 19 connects the two sides of the lower pressure plate 22, which can improve the stability of the lower pressure plate 22 during the extension and retraction process.

[0042] refer to Figure 5 The drive mechanism 13 has limit rings 20 on both sides. The limit rings 20 are fixedly connected to the connecting mechanism 12 by bolts. The limit rings 20 have a through circular hole in the middle. The second telescopic rod 19 is located inside the circular hole inside the limit ring 20. It is used to limit the second telescopic rod 19 so that the second telescopic rod 19 can only slide up and down. Specifically, the second telescopic rod 19 slides up and down in the circular hole.

[0043] refer to Figure 5 The top end of the second telescopic rod 19 is fixedly connected to a limiting block 21. The limiting block 21 is fixedly connected to the second telescopic rod 19 by welding. The cross-sectional diameter of the limiting block 21 is larger than the diameter of the circular hole in the middle of the limiting ring 20. So when the pressure plate 22 is pressed down to the limit, the limiting block 21 and the limiting ring 20 come into contact. The limiting block 21 can limit the second telescopic rod 19 and prevent the second telescopic rod 19 from sliding excessively.

[0044] refer to Figure 5 The lower pressure plate 22 and the support platform 24 are arranged parallel to each other. When the laser is emitted, it is perpendicular to the steel plate on the support platform 24, which can improve the accuracy of laser measurement. Friction blocks 25 are fixedly connected to the four corners of the top of the support platform 24. The friction blocks 25 can increase the friction force on the contact surface with the steel plate and can stably fix the steel plate. The bottom of the support platform 24 is fixedly connected to the top of the placement box 1 by screws. The support platform 24 is rectangular, so the steel plate can be stably placed on the support platform 24.

[0045] refer to Figure 3 The spacing between the placement plates 14 is consistent, which ensures that the weight in the placement box 1 is relatively even. The placement plate 14 has an embedded groove inside, which can limit the steel plate and prevent the steel plate from sliding out of the placement box 1. Sliding blocks 26 are fixedly connected to both ends of the placement plate 14. Slide rails 27 are fixedly connected to both ends inside the placement box 1. The sliding blocks 26 are located inside the slide rails 27 and are slidably connected to the slide rails 27. The placement plate 14 can be easily installed by inserting the sliding blocks 26 into the slide rails 27. It is also easy to disassemble the placement plate 14 when needed.

[0046] Furthermore, when the terms "first," "second," "third," etc., are used in this application specification to describe various features, these terms are only used to distinguish these features and should not be construed as indicating or implying the correlation or relative importance between features or implicitly indicating the number of features indicated.

[0047] In addition, this application specification describes exemplary embodiments by referring to idealized exemplary cross-sectional views and / or plan views and / or perspective views. Therefore, differences from the illustrated shapes are foreseeable due to factors such as manufacturing techniques and / or tolerances. Therefore, exemplary embodiments should not be construed as limited to the shapes of the regions shown herein, but should include deviations in shape caused, for example, by manufacturing processes. Thus, the regions shown in the figures are substantially schematic, and their shapes are not intended to illustrate the actual shapes of the regions of the device, nor to limit the scope of the exemplary embodiments.
