Description

Technical Field

[0001] The present application relates to the technical field of steel coil scales, and in particular to a detection device for an online steel coil scale. Background Art

[0002] The steel coil scale is a special measuring instrument used by steel mills for online weighing of steel coils on hot rolling and cold rolling production lines. It is a type of non-automatic scale. When weighing steel coils, the steel coils need to be pushed onto the steel coil scale for weighing, so as to know the weight of the steel coils.

[0003] During the use of steel coil scales, calibration is required. Generally, weights need to be placed on the steel coil to calculate the weight difference before and after the weights are placed. However, due to the special structure of the steel coil scale, the weights are prone to slipping, which brings great trouble to the calibration work. Summary of the invention

[0004] The purpose of this application is to provide a detection device for an online steel coil scale to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, this application provides the following technical solutions:

[0007] As a further solution of the present application: fixing seats are installed around the top of the automatic weighing instrument, and a flat plate is placed on the top of the fixing seats.

[0008] As a further solution of the present application: limiting columns are installed on the four sides of the bottom end of the flat plate, and limiting grooves are correspondingly provided at the top end of the fixing seat below the limiting columns.

[0010] As a further solution of the present application: an alarm light is installed on the top of the weighing platform above the processor, and the alarm light is located in the middle position of one end of the top of the weighing platform.

[0011] Compared with the prior art, the beneficial effects of this application are:

[0012] 1. The detection equipment for the online steel coil scale automatically weighs the steel coil by placing it on the steel coil scale body and on the top of the automatic scale. The processor compares the weighing values ​​of the two. If an error occurs, the alarm light is controlled to alarm, and it can be preliminarily determined whether the steel coil scale body is qualified, thus solving the problem of inconvenience in calibrating the steel coil scale.

[0013] 2. This pair of online steel coil scale detection equipment, when there is a numerical difference, installs a flat plate on the top of the steel coil scale body, and then places the standard vertical weight inside the protective frame for weighing, to achieve the calibration of the automatic scale, avoid malfunction or error of the automatic scale, and thus solve the problem of lack of calibration of auxiliary equipment.

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] like Figure 1-3 In this embodiment, a detection device for an online steel coil scale includes: a weighing platform 1, tracks 4 are installed on both sides of the lower end of the weighing platform 1, and a hydraulic lifting trolley 3 is installed between the tracks 4, a steel coil scale body 2 is installed on one side of the top of the weighing platform 1, and an automatic weighing device 5 is installed on the other side of the top of the weighing platform 1, and a processor 9 is installed at the middle position of the top of one end of the weighing platform 1.

[0020] like Figure 1 and Figure 3 In this embodiment, a fixing seat 10 is installed around the top of the automatic weighing device 5, and a flat plate 6 is placed on the top of the fixing seat 10.

[0021] It should be noted that the additional plate 6 is mounted on the top of the automatic weighing instrument 5 to facilitate the calibration of the automatic weighing instrument 5 .

[0022] like Figure 1 and Figure 3 In this embodiment, the four sides of the bottom end of the flat plate 6 are all installed with limiting columns 11, and the top of the fixing seat 10 below the limiting columns 11 is correspondingly provided with limiting grooves 12.

[0023] It should be noted that the limiting installation of the plate 6 is achieved by inserting the limiting column 11 into the limiting groove 12 .

[0024] like Figure 1 and Figure 3 In this embodiment, a protective frame 7 is installed at the middle position of the top of the flat plate 6, and the top view shape of the protective frame 7 is a circular shape.

[0025] It should be noted that by placing a standard vertical weight inside the protective frame 7 for weighing, it is possible to effectively avoid the weight from falling.

[0026] like Figure 1 and Figure 2 In this embodiment, an alarm light 8 is installed on the top of the weighing platform 1 above the processor 9, and the alarm light 8 is located in the middle position of one end of the top of the weighing platform 1.

[0027] It should be noted that the weighing results of the steel coil scale body 2 and the automatic weighing device 5 are statistically compared through the processor 9. If an error occurs, the alarm light 8 is controlled to give an alarm, so that the staff can find it in time.

[0028] It can be understood that the detection equipment for the online steel coil scale is assisted in weighing by the external automatic weighing device 5. When there is an error in the weighing of the two, it can be judged in time whether the steel coil scale is qualified.

[0029] The working principle of the above embodiment is:

[0030] During operation, the steel coil is placed on the top of the hydraulic lifting trolley 3 by means of a lifting device, and then the hydraulic lifting trolley 3 moves and descends to place the steel coil on the top of the steel coil scale body 2 for weighing, and then placed on the top of the automatic weighing device 5 for automatic weighing. At this time, the weighing results of the steel coil scale body 2 and the automatic weighing device 5 are statistically compared by the processor 9. If an error occurs, the alarm light 8 is controlled to give an alarm. At the same time, the steel coil scale body 2 and the automatic weighing device 5 can continuously accumulate the weight values ​​of the steel coil weighed within a certain period of time, and finally the difference is compared and calculated by the processor 9, so as to judge whether the steel coil scale body 2 is accurate.

[0031] At the same time, when a numerical difference occurs, the plate 6 can be picked up so that the limit column 11 is inserted into the limit groove 12 to achieve the limit installation of the plate 6, and the standard vertical weight can be placed inside the protective frame 7, thereby realizing the calibration of the automatic weighing instrument 5 and avoiding malfunction or error of the automatic weighing instrument 5.

[0032] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
