Description

Technical Field

[0001] The utility model belongs to the field of measuring equipment, in particular to a device for measuring the height of a water column of a layer cooling lower header. Background Art

[0002] Laminar cooling is a key process for cooling hot-rolled strip from the finishing exit temperature to the coiling temperature. During the laminar cooling process, the cooling equipment is mostly composed of several groups of upper and lower headers. During the production process, water flows downward from the upper header to form a "water curtain", and water sprays vertically upward from the lower header to form a "water column". Due to the presence of some tiny iron oxide slag and sludge in the laminar cooling water, the water column of the lower header of the laminar cooling equipment is easily blocked after long-term use, resulting in a decrease in the height of the water column of some lower headers, and the cooling intensity of the lower surface of the strip is weakened, affecting the strength performance of the lower surface of the hot-rolled strip, and also causing U-shaped or turtle-back defects in wide and thick strips. In order to reduce the defects of hot-rolled strip products caused by the decrease in the height of the water column of the lower header of laminar cooling, it is necessary to calibrate the height of the water column of the lower header of laminar cooling regularly.

[0003] Currently, the water column height is calibrated by manual judgment, which has poor accuracy and requires personnel to get close to the laminar cooling conveyor roller to judge the height of the water column in the laminar cooling lower header, which is not very safe. Utility Model Content

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-2As shown, the embodiment of the utility model provides a device for measuring the water column height of the layer cooling lower header, including a measuring main ruler 1, the measuring main ruler 1 is convenient for the staff to measure the water column height of the layer cooling lower header, the measuring main ruler 1 is fixedly connected to the supporting bottom plate 2, and a plurality of supporting columns 3 are arranged between the supporting bottom plate 2 and the measuring main ruler 1, and the plurality of supporting columns 3 can stabilize the measuring main ruler 1, ensure that the measuring main ruler 1 is in a vertical and stable position, avoid measurement errors caused by instability, and increase the stability of the overall structure;

[0021] When it is necessary to measure the height of the water column of the layer cooling lower header, the entire supporting base plate 2 is lifted onto the layer cooling conveying roller, and the layer cooling lower header water is turned on. The layer cooling water forms a water column of a certain height. The plane frame formed by the entire supporting base plate 2 does not affect the water spraying of the layer cooling lower header around the measuring main scale 1. The lower header water column is close to the measuring main scale 1 for easy reading. The layer cooling conveying roller is started, and the entire supporting base plate 2 can move along the layer cooling conveying roller to measure the height of the lower header water column in different areas of the layer cooling. The measurement accuracy and efficiency of the layer cooling water column height can be improved without personnel approaching the layer cooling conveying roller.

[0022] In one embodiment, see Figure 1 and Figure 2 As shown, the support base plate 2 includes two support main boards 21 and a support connecting plate 22. The support connecting plate 22 is an integrated frame structure for connecting the two support base plates 2. A measuring main scale 1 is arranged on the support connecting plate 22. A support connecting plate 22 is arranged between the two support main boards 21. A plurality of support columns 3 are arranged between the support connecting plate 22 and the measuring main scale 1. The support base plate 2 consists of a support main board 21 and a support connecting plate 22. The support connecting plate 22 is used to connect the two support main boards 21. By using the support connecting plate 22 to connect the two support main boards 21, the structural stability of the entire support base plate 2 can be increased, and it can be ensured that the entire base plate will not be twisted or deformed during the measurement process, thereby ensuring the accuracy of the measurement. The support connecting plate 22, as a component connecting the two support main boards 21, makes the installation and disassembly of the support base plate 2 easier, which can facilitate maintenance and cleaning, and also increases the operability of the device.

[0023] In one embodiment, see Figure 1 and Figure 2As shown, the supporting main board 21 includes a mounting plate 211 and an arc plate 212. A supporting connecting plate 22 is arranged on the mounting plate 211. Arc plates 212 are arranged on both sides of the mounting plate 211. The arc plates 212 are arranged on both sides to increase the stability of the mounting plate 211 and prevent it from twisting or deforming during the measurement process, thereby ensuring the accuracy of the measurement. This can simplify the assembly process and improve the operability of the device. The combination of the mounting plate 211 and the arc plate 212 can increase the overall rigidity of the supporting main board 21, so that it can better withstand various forces and pressures during the measurement process, thereby maintaining stability. Using the arc plate 212 as a part of the supporting main board 21 can increase its durability and lifespan. The arc structure usually has good load-bearing capacity and anti-deformation ability.

[0024] In one embodiment, see Figure 1 and Figure 2 As shown, the angle between the arc plate 212 and the mounting plate 211 is α, and the preferred angle α is 45°, which prevents the support main board 21 from twisting or deforming during the measurement process. The 45° angle can provide a suitable support angle, so that the support main board 21 can better support other components and withstand the pressure of the water column.

[0025] In one embodiment, see Figure 1 and Figure 2 As shown, a polyurethane layer is provided on the arc plate 212 , and the polyurethane layer can reduce the friction between the arc plate 212 and other components, thereby reducing the wear degree of the arc plate 212 .

[0026] In one embodiment, see Figure 1 and Figure 2 As shown, the measuring main ruler 1 is provided with scales 4 all around, and the scales 4 provided all around are convenient for operators to read, thereby improving the accuracy and reliability of the measurement. The height of the water column of the layer cooling lower header can be measured from multiple angles without adjusting the position of the measuring main ruler 1. Since the scales 4 are clearly visible, the operator can directly read the scale, which reduces the possibility of human reading errors and improves the accuracy of the measurement. The measurement results can be confirmed from different directions, and the operator can accurately read the measurement results even if he stands in different positions.

[0027] In one embodiment, see Figure 1 and Figure 2 As shown, the scale 4 is detachably connected around the main measuring scale 1. The detachable scale 4 can be easily maintained and replaced. If the scale 4 is damaged or needs to be cleaned, it can be easily disassembled for processing without affecting the use of the entire measuring device.
