Description

Technical Field

[0001] This application belongs to the technical field of measuring equipment for steel rolling, and specifically relates to a weighing device and a steel rolling transport chain. Background Art

[0002] During the hot rolling production process, accurately measuring the weight of steel coils using an online scale is a crucial step. As the third-level trade scale between factories, the measurement data of this online scale is not only related to the monitoring of the production process but also directly affects the accuracy of trade settlement. The measurement data is transmitted in real-time to the first-level PLC system (Programmable Logic Controller) and the third-level system. The PLC system is responsible for receiving, processing, and storing this data to ensure the integrity and traceability of the data. The PLC system also transmits the processed data to the main control operation screen for operators to view and compare in real-time. The third-level system is a higher-level data management system for further data analysis and report generation. Through the accurate measurement of the online scale, it can be ensured that the weight of the steel coil meets the requirements, avoiding trade disputes caused by weight deviations. At the same time, accurate measurement data also helps enterprises with production management and quality control.

[0003] Since the scale body of the online scale is installed on the transport chain, and the transport trolley roller path is installed on the scale body, and it is entirely supported by four sensors, and the four sensors designed are 200 mm away from the outermost edge of the scale body, so when measuring the heavy coil trolley getting on and off the scale body, there will be a phenomenon of tilting forward and backward; because the scale body is in a movable state, when the trolley walks on the scale body, there will be a phenomenon of swaying forward and backward. These two phenomena cause great damage to the measurement sensors. After a long time of use, there will be a large measurement deviation, and even the sensors will be directly damaged by impact, directly affecting the detection. If the online scale loses its detection function, the rolling line will stop discharging steel for processing, affecting the production rhythm. If the measurement deviation is large, there will be objections to the weight of the batch of strip materials, resulting in incalculable economic losses. Summary of the Invention

The weighing device includes: a base 100, which is arranged in a weighing pit of a steel rolling production line; an induction component 200, which is used to sense the weight of a steel coil. The induction component 200 includes four induction units, and the four induction units are arranged at the four corners of the base 100; a bearing plate 300, which is fixed on the induction component 200. The steel bars to be detected are transported onto the bearing plate 300 and weighed through the induction component 200; a limiting component 400, which is arranged between the bearing plate 300 and the base 100 bracket. The limiting component 400 is used to prevent the bearing plate 300 from shaking radially during weighing. By setting the limiting component 400 to limit the radial direction of the bearing plate 300, the weighing body can be stabilized when the trolley moves onto the bearing plate 300, effectively avoiding the phenomenon that the weighing trolley tilts forward and backward when getting on and off the weighing body, reducing the damage to the sensor caused by the shaking of the weighing body, and thus improving the accuracy of the finished strip steel measurement and detection.

[0025] In some embodiments, since a trolley is used in this embodiment to transport the steel plate to the bearing plate 300, the bearing plate 300 will shake in the traveling direction of the trolley (i.e., the radial direction of the bearing plate 300). Therefore, in this embodiment, only limiting units are arranged on the transverse sides of the base 100. In other embodiments, if hoisting or other transportation methods are used for weighing, limiting units can also be arranged on the four sides of the base 100 to prevent the bearing plate 300 from shaking.

[0026] In some embodiments, the induction component 200 includes at least two limiting units, and the limiting units are respectively arranged on the transverse sides of the base 100. There are four limiting units, and the four limiting units are respectively arranged close to the four induction units. In other embodiments, three or four or more limiting units can also be arranged on the transverse sides of the base 100.

Specifically, the clamping member 420 is in an "L" shape, and the contact surface between the clamping plate 423 and the limiting plate 422 is perpendicular to the radial direction of the support plate.

[0030] In some embodiments, a set screw hole 424 is formed in the clamping plate 423 and the limiting plate 422 of the lower clamping member 420, and the set screw is installed in the set screw hole 424 so that the distance between the set screw and the upper clamping member 420 is kept within 1-2 mm to ensure the frame movement gap during operation.

[0031] In some embodiments, the mounting plate 421 and the fixing plate 410 are connected by bolts.

[0032] In some embodiments, the sensing unit includes: a weighing sensor 210, which is used to sense the weight of the bearing plate 300; two top bowls 220, and the sensors are respectively connected to the base 100 and the bearing plate 300 through the two top bowls 220. Specifically, the lower top bowl 220 is set as a plane, and the upper top bowl 220 is set as an arc surface.

[0035] In the second aspect of the embodiments of the present application, a steel rolling transport chain is provided. The weighing device described above is arranged on the steel rolling transport chain. The transport chain transports the steel coil to the bearing plate 300 for weighing through a transport trolley. By arranging a limiting component 400, the radial direction of the bearing plate 300 is limited, and the weighing body is stabilized when the trolley moves onto the bearing plate 300, which can effectively avoid the phenomenon that the weighing trolley tilts forward and backward when getting on and off the weighing body, and reduce the damage to the sensor caused by the shaking of the weighing body.
