The method has the advantages of simplifying the checking step, reducing the working strength of operators and realizing quick, accurate and convenient checking.

Description

Calibration device

technical field

The invention relates to a weighing device, in particular to a weighing device suitable for a weighing device on a roller table of a furnace, and belongs to the technical field of production. the

Background technique

As shown in Figure 1, the existing technology is usually: at the weighing device of the roller table, fix the steel billet weight 9 with a chain, and then lift it to the weighing device by driving, and retract the hydraulic cylinder 6 to lift the weighing device. Weighing is carried out, and the steel billet weight 9 is hoisted away after the checking is finished, thereby completing the whole checking and weighing process. This checking method is rather cumbersome. If the scale is checked when the shift is handed over, the above-mentioned cranes are often busy with hoisting the rolling mill, guides, etc., resulting in delays in the scale calibration and affecting the production process. the

Contents of the invention

The purpose of the present invention is to provide a calibration device that solves the above problems. the

The purpose of the present invention is achieved through the following technical solutions:

A calibration and weighing device, including a weighing unit and a calibration and weighing unit, the weighing unit includes a first roller table for calibration, a second roller table for carrying weighing objects, connecting the first roller table and The scale beam of the second roller table and the weighing bracket supporting the scale beam, the correction unit includes billet weights, shackles arranged on the steel billet weights and U The shackle is movably buckled on the U-shaped plate, and the billet weight can be connected and suspended on the first roller table.

Further, the weighing unit further includes one or more sets of hydraulic cylinders and connection devices, and the hydraulic cylinders are connected to and control the first roller table through the connection devices. One or more sets of hydraulic cylinders and connecting devices may be provided according to the length of the first roller table, thereby supporting and controlling the first roller table. the

Further, the cross section of the first roller table or the second roller table is H-shaped or concave. the

Further, the shackle is semi-circular. the

The beneficial effects of the present invention are mainly reflected in that the checking steps are simplified, the work intensity of operators is reduced, and quick, accurate and convenient checking is realized. the

Detailed ways

Please refer to Fig. 2, the present invention adopts the following technical solutions, including the first roller table 1 for correction, the second roller table 3 for carrying weighing objects, the connecting first roller table 1 and the second roller table 3 The scale beam 2 and the weighing bracket 4 supporting the scale beam 2 also include a steel billet weight 9, a shackle 8 arranged on the steel billet weight 9 and a U-shaped plate 7 installed under the first roller table 1, and the shackle 8 is movable The ground buckle fits in the U-shaped groove of the U-shaped plate to connect and hang the billet weight 9 on the first roller table 1 . As shown in FIG. 2 , this embodiment also includes a plurality of sets of hydraulic cylinders 6 and a connection device 5 , and the hydraulic cylinders 6 are connected to and control the first roller table through the connection device 5 . According to the length of the first roller table 1 in this embodiment, four sets of the above-mentioned multiple sets of hydraulic cylinders and connecting devices are provided to support and control the first roller table. the

When the present invention works, the steel billet weight 9 is placed under the steel structure of the first roller table 1, and when the scale needs to be checked, the shackle 8 is hung in the U-shaped groove of the U-shaped plate, and the hydraulic cylinder 9 is stretched out to make it The first roller table 1 is lifted to drive the steel billet weight 9, thereby realizing checking. After checking, it is only necessary to take back the hydraulic cylinder 9 and unclamp the shackle 8 to get final product. the

The present invention still has many specific implementation modes, and all technical solutions formed by adopting equivalent replacement or equivalent transformation all fall within the protection scope of the present invention. the
