Description

Technical Field

[0001] The utility model belongs to the technical field of billet weighing, in particular to a steel rolling billet weighing device. Background Art

[0002] In the steel rolling production process, it is generally necessary to know the weight of the billet in order to ensure the yield rate of steel rolling production in terms of weight. There are generally two ways to obtain the weight of the billet. One is to calculate it through theoretical values. However, if the billet is out of square, the billet is ground (size reduction), or the billet is abnormally sized, there will be a large error in the theoretical calculation, and the actual weight of the billet cannot be obtained. This may cause a large deviation between the theoretical weight after steelmaking and the calculated weight, and the steelmaking process cannot be adjusted. The other is to install the weighing module under the conveyor roller, and weigh the billet directly while passing through the roller. Since the billet moves forward continuously with the roller, the billet weighing will be inaccurate. Utility Model Content

[0003] In view of the above problems existing in the prior art, the purpose of the utility model is to provide a weighing device for rolled steel billets.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is as follows:

[0005] A rolled steel billet weighing device comprises a plurality of lifting devices and a weighing device. The lifting devices are used to lift the billets, and the weighing device is arranged below the lifting devices and is used to weigh the billets. At this time, the billets are stationary, and the weighing results are more accurate and stable.

[0006] Furthermore, the lifting device includes a lifting rod, a connecting plate assembly and a driving device. The lifting rod is arranged above the connecting plate assembly to lift the square billet, and the driving device is arranged below the connecting plate assembly to raise and lower the lifting rod through the connecting plate assembly.

[0007] Furthermore, the connecting plate assembly includes a fixed plate, a first connecting plate, a second connecting plate, a third connecting plate and a fourth connecting plate, one end of the second connecting plate and the third connecting plate are respectively rotatably connected to the fixed plate, and the other ends of the second connecting plate and the third connecting plate are respectively rotatably connected to the fourth connecting plate, so that the driving device can more conveniently lift the connecting plate assembly.

[0008] Furthermore, it also includes a fifth connecting plate and a rocker arm. The fifth connecting plate is arranged on the fixed plate and connected to the first connecting plate and the second connecting plate through a total pin shaft. The two ends of the rocker arm are respectively rotatably connected to the fifth connecting plates of the two adjacent connecting plate assemblies, so as to drive several connecting plate assemblies to move synchronously for better linkage.

[0009] Furthermore, the top of the driving device is rotatably connected to the bottom of the first connecting plate to drive the connecting plate assembly to move.

[0010] Furthermore, it also includes a lifting baffle, which is arranged at the terminal end of the roller table and is used to prevent the movement of the billet.

[0011] Furthermore, the weighing device is a dynamic load weighing module to facilitate transmission of weighing results.

[0012] Furthermore, it also includes a control console, which is connected to the conveyor roller and is used to control the start and stop of the conveyor roller. The control console is connected to the lifting baffle and is used to control the lifting and lowering of the lifting baffle. The control console is connected to the lifting device and is used to control the lifting and lowering of the lifting device. The control console is connected to the weighing device and is used to transmit the measured signal to the control console.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

The preferred rotating connection fastener is a pin. The fifth connecting plate 18 is arranged on the fixed plate 8 at the same position as the first connecting plate 9 and the second connecting plate 10, and moves synchronously through the main pin 17. The driving device 14 is arranged on the bracket 3 of the roller seat 1, and its top end is connected to the bottom of the first connecting plate 9 for rotation through the pin 13. Both ends of the swing rod 4 are rotatably connected to the fifth connecting plates 18 of two adjacent connecting plate assemblies 5, respectively, for driving several connecting plate assemblies 5 to move synchronously (the number of connecting plate assemblies 5 can be set as needed, and 7 here is only an example).

[0024] In this embodiment, the preferred driving device 14 is a cylinder.

[0025] The utility model further comprises a lifting baffle 7, which is arranged at the terminal end of the conveying roller 19 and is used to block the movement of the billet, so as to facilitate the lifting device 2 to lift the billet for weighing.
