Description

Technical Field

[0001] This utility model relates to the field of crown measurement technology, and in particular to an automatic cleaning device for the measuring surface of a hot rolling crown measurement instrument. Background Technology

[0002] In hot rolling production, a crown gauge is installed at the F7 exit of the finishing mill. The crown gauge accurately measures data such as the crown and wedge shape of the strip at the finishing mill exit. The crown and wedge measurement data are sent to the primary PLC system and the secondary system to establish a strip shape data model and form a crown closed-loop feedback control with the strip shape control system.

[0003] Furthermore, because the crown gauge is located at the F7 exit of the finishing mill, it is relatively close to the water spray on the exit side. During the strip rolling process, a large amount of dust and water are generated. The dust and water mix together, and coupled with the high temperature of the strip itself, the water vapor evaporates rapidly, causing the contaminants to adhere to the measuring surface of the lower arm of the C-frame. Over time, impurities of varying thicknesses will form on the measuring surface, directly affecting the measurement of the crown profile. This causes the secondary model to automatically adjust the thickness, ultimately resulting in discrepancies in the crown of batch strips and incalculable economic losses.

[0004] Currently, manual wiping is performed once every roll change period, which results in a large amount of manual work and low production efficiency due to the need to stop rolling for cleaning. An automatic cleaning device for the measuring surface is needed. Utility Model Content

[0005] To address the aforementioned problems, this application provides an automatic cleaning device for the measuring surface of a hot rolling crown tester.

[0006] This application provides an automatic cleaning device for the measuring surface of a hot rolling crown gauge, including a base, a telescopic component, a cleaning assembly, and a control assembly. The base is fixedly connected to the roller conveyor frame after the hot rolling mill exit. The telescopic component is connected to the base, and a mounting plate is connected to the telescopic end of the telescopic component. The cleaning assembly includes a first nozzle, a roller brush motor with a brush, and an air knife, which are sequentially mounted on the mounting plate. The first nozzle is connected to a water tank containing detergent and a first solenoid valve is installed on the connecting pipeline. The roller brush motor is equipped with an electrically controlled relay. The air knife is connected to an air source and a second solenoid valve for control is installed on the connecting pipeline. The control assembly includes a first limit switch. The device includes a switch, a second limit switch, and a controller. The first and second limit switches are mounted on the fixed beam of the C-frame of the convexity meter. The first and second limit blocks configured for the first and second limit switches are both mounted on the top side of the C-frame. The distribution of the second limit blocks in the direction from the measuring position to the parking position of the convexity meter is consistent with that of the measuring surface protective plate of the C-frame. The first limit switch is used to detect whether the convexity meter has left the measuring position. The controller is connected to the first and second limit switches, the first solenoid valve, the relay, the second solenoid valve, and the third solenoid valve that controls the telescopic component.

[0007] In some implementations, the base is a channel steel.

[0008] In some implementations, the telescopic component is a cylinder, which is connected to an air source, and a third solenoid valve is installed on the connecting pipeline between the cylinder and the air source.

[0009] In some implementations, the cylinder port is fitted with a quick-connect coupling.

[0015] In some implementations, a bracket is welded onto the mounting plate, and the air knife is mounted on the bracket.

[0016] The beneficial effects of this application are as follows: It provides an automatic cleaning device for the measuring surface of a hot rolling crown gauge. The controller obtains the time point when the C-frame leaves the measuring position through a first limit switch and a first limit stop. The controller obtains the time range for cleaning the measuring surface protective plate through a second limit switch and a second limit stop, thus smoothly controlling the cleaning assembly to perform cleaning operations on the measuring surface protective plate. This device is fixed to the roller conveyor frame after the hot rolling mill exit via a base. A telescopic component installed on the base controls the installation plate to move towards the measuring surface protective plate during cleaning, allowing the cleaning assembly mounted on the installation plate to perform the cleaning operation. The cleaning assembly includes a first nozzle, a roller brush motor with a brush, and an air knife, sequentially installed on the installation plate. During the movement of the C-frame of the crown gauge from the measuring position to the parking position, the C-frame and the cleaning assembly... The sweeping components move relative to each other, and the first nozzle sprays a mixture of detergent and water onto the measuring surface protective plate. The detergent reacts with the debris on the measuring surface protective plate. Under the action of the subsequent roller brush motor, the brush performs a thorough sweeping of the measuring surface protective plate without dead angles. Then, an air knife blows and cleans the measuring surface protective plate, removing foreign matter, dirt, and detergent adhering to the protective plate, further improving the cleanliness of the measuring surface. The automatic cleaning device provided in this application replaces manual cleaning of the measuring surface of the hot rolling crown gauge, achieving the effect of automatically cleaning debris from the measuring surface without manual intervention. This effectively improves cleaning efficiency, increases the utilization rate of on-site personnel in a smart factory with reduced human intervention, reduces the downtime caused by cleaning the measuring surface, and ultimately improves the hot rolling production efficiency.

Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0023] First, please allow me to introduce the hot rolling crown gauge. The crown gauge is equipped with a C-shaped frame 22, which is referenced... Figure 1 As shown, the C-frame 22 is horizontally distributed, and the upper and lower supports of the C-frame 22 are respectively provided with a radiation exit chamber and a detection ionization chamber on their sides where they are close to each other. Figure 1 As shown in the diagram, the X-ray window 22b and the measuring face shield 22a are located on the upper side of the detection ionization chamber. The C-frame 22 can move between the measuring position and the parking position. When in the measuring position, it accurately measures data such as strip crown and wedge shape. When not measuring, it needs to be moved to the parking position.

[0024] Please refer to the reference. Figure 1 and Figure 2 This application provides an automatic cleaning device for the measuring surface of a hot rolling crown tester, including a base 100, a telescopic member 200, a cleaning assembly, and a control assembly.

[0025] In hot rolling production, the crown gauge is installed at the F7 exit of the finishing mill. In this application, the base 100 is fixedly connected to the roller frame after the hot rolling mill exit, and the base 100 provides the installation foundation for the overall structure.

[0026] The telescopic component 200 is connected to the base 100, and the telescopic end of the telescopic component 200 is connected to the mounting plate 210. The cleaning component is mounted on the mounting plate 210. The telescopic component 200 mounted on the base 100 is used to control the movement of the mounting plate 210 toward the measuring surface protective plate 22a during cleaning, so that the cleaning component mounted on the mounting plate 210 can perform the cleaning work position.

[0027] The cleaning assembly includes a first nozzle 310, a roller brush motor 320 with a brush, and an air knife 330, sequentially mounted on the mounting plate 210. The first nozzle 310 is connected to a water tank 311 containing detergent, and a first solenoid valve 312 is installed on the connecting pipe. The roller brush motor 320 is equipped with an electrically controlled relay, and the air knife 330 is connected to an air source 332, and a second solenoid valve 331 is installed on the connecting pipe. It should be noted that the arrangement direction of the first nozzle 310, roller brush motor 320, and air knife 330 is from the measurement position to the parking position of the convexity meter. The measuring surface protective plate 22a is cleaned sequentially by the first nozzle 310, roller brush motor 320, and air knife 330.

[0028] The control assembly includes a first limit switch 410, a second limit switch 420, and a controller. The first and second limit switches 410 and 420 are mounted on the fixed beam 21 of the C-frame 22 of the convexity meter. The first limit block 411 configured on the first limit switch 410 and the second limit block 421 configured on the second limit switch 420 are both mounted on the top side of the C-frame 22. The first limit switch 410 is used to detect whether the convexity meter has left the measurement position. The controller obtains the time point at which the C-frame 22 leaves the measurement position through the first limit switch 410 and the first limit block 411. Furthermore, the second limit block 421 is distributed in accordance with the distribution of the measurement surface protective plate 22a of the C-frame 22 in the direction from the measurement position to the parking position. The controller obtains the time range for cleaning the measurement surface protective plate 22a through the second limit switch 420 and the second limit block 421.

[0029] The controller is connected to the first limit switch 410, the second limit switch 420, the first solenoid valve 312, the relay, the second solenoid valve 331, and the third solenoid valve of the control telescopic component 200. The controller can smoothly control the cleaning component to perform cleaning operations on the measuring surface protective plate 22a.

[0030] When the measuring surface protective plate 22a needs to be cleaned, the C-frame 22 of the convexity meter moves from the measuring position to the parking position. When the first limit switch 410 loses its signal, the controller determines that the C-frame 22 is leaving the measuring position based on this information, controls the extension member 200 to extend, and controls the mounting plate 210 to move toward the measuring surface protective plate 22a, so that the cleaning component mounted on the mounting plate 210 is in the cleaning working position. At this time, the C-frame 22 and the cleaning component move relative to each other. The first nozzle 310 sprays a mixed water agent containing detergent onto the measuring surface protective plate 22a. The detergent reacts with the debris on the measuring surface protective plate 22a. Under the action of the subsequent roller brush motor 320, the brush performs a thorough roller sweeping of the measuring surface protective plate 22a. Then, the air knife 330 blows and cleans the measuring surface protective plate 22a, removing foreign matter, dirt and detergent adhering to the protective plate, further improving the cleanliness of the measuring surface.

[0031] The automatic cleaning device provided in this application replaces manual cleaning of the measuring surface of the hot rolling crown gauge, achieving the effect of automatically cleaning debris from the measuring surface without manual intervention. This effectively improves cleaning efficiency, increases the utilization rate of on-site personnel in a smart factory with reduced human intervention, reduces the downtime caused by cleaning the measuring surface, and ultimately improves the production efficiency of hot rolling.

[0032] In some embodiments, the cleaning assembly further includes a second nozzle, which is installed between the roller brush motor 320 and the air knife 330. The second nozzle is connected to the air source 332 and a fourth solenoid valve is installed on the connecting pipeline. The fifth solenoid valve is signal-connected to the controller. Since the cleaning assembly only includes a first nozzle 310, a roller brush motor 320 with a brush, and an air knife 330, directly blowing the measuring surface protective plate 22a of the roller brush with the air knife 330 results in incomplete cleaning of debris, a second nozzle is added to the cleaning assembly. The working state of the second nozzle is switched by the fourth solenoid valve and controlled by the controller. This allows for an additional water wash of the measuring surface protective plate 22a before air cleaning with the air knife 330, improving the aforementioned incomplete cleaning and further enhancing the cleaning efficiency.

[0033] In some embodiments, the base 100 is a channel steel.

[0034] In some embodiments, the telescopic member 200 is a cylinder, which is connected to the air source 332. A third solenoid valve is installed on the connecting pipeline between the cylinder and the air source 332, and high-pressure air is provided to the cylinder and the air knife 330 through the same air source 332.

[0035] In some implementations, the cylinder port is equipped with a quick connector, which enables quick assembly and disassembly of the air hose.

[0036] In some implementations, the air knife 330 is connected to a quick connector, which enables quick assembly and disassembly of the air tube.

[0037] In some embodiments, the pipes connected to the first nozzle 310, the air knife 330, and the cylinder are all flexible hoses, which are limited by the on-site pipe installation and layout.

[0038] In some implementation methods, please refer to Figure 2 The mounting plate 210 is connected to the bearing support 211, and the roller brush motor 320 is mounted on the bearing support 211.

[0039] In some embodiments, a bracket is welded onto the mounting plate 210, and the air knife 330 is mounted on the bracket.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.
