After the steel is placed directly on the lifting member or indirectly on top of the lifting member, the steel is lifted by controlling the lifting member to rise relative to the fixed bearing member. The limiting component's limiting effect constrains the fixed bearing member. The offset and sway in the X-axis direction, even though the steel still has a certain speed when placed, can help the steel stabilize quickly after being lifted, thus obtaining a stable reading weight as soon as possible. This reduces the weighing time and improves measurement efficiency. The weight of the steel is the difference between the stable reading weight and the initial weight when the steel is not loaded. The limiting component in the X-axis direction does not affect the weighing, and since there is no constraint in the Z-axis direction, it does not affect the weighing reading. In summary, the setting of fixed load-bearing components ensures that the entire weighing process is relatively simple, and the relevant weighing structure generally does not require sophisticated modules. The reasonable structure can improve measurement efficiency while ensuring measurement accuracy. Attached Figure Description

[0045] Specifically, the lifting pieces 7 are provided with multiple pieces, and every two pieces are placed in the square grooves in the middle of the lifting carriers 62 in the lifting pieces 6, which are used to support the steel 11. When waiting for weighing, the lifting carriers 62 of the lifting pieces 6 are generally located at a position relatively below the fixed carriers 3, so that the upper surface (the lowest height) of the lifting pieces 7 is lower than the fixed carriers 3.

[0049] As an optional embodiment of the utility model, the limiting assembly 8 is provided with multiple groups and corresponds to multiple bases 1 one by one, and each base 1 is gap-fitted with the corresponding support sheet 81.

[0052] Specifically, the fixed bearing 3 is arranged in the transportation process of the steel material 11, that is, arranged at a position of the transportation roller assembly 9, and the transportation roller assembly 9 can transport the steel material 11 to above the fixed bearing 3, and then the lifting member 6 drives the lifting member 7 to extend and lift the steel material 11, it can be inferred that the height of the fixed bearing 3 must be not higher than the surface height of the transportation roller assembly 9, so as not to affect the transportation of the steel material 11, and the transportation roller assembly 9 will not affect the lifting and weighing of the steel material 11.

[0053] As shown in FIG. 1, Figure 5 , Figure 7 ,Figure 8 and Figure 9 As shown in Fig. 9, which is an alternative embodiment of the present application, the transport roller assembly 9 comprises a plurality of transport rollers arranged along the length direction of the fixed carrier 3, the lowest position of the top surface of the lifting member 7 is lower than the surface of the transport roller, a spacing space 10 is arranged between two adjacent transport rollers, the lifting connecting member 61 is arranged on both sides of the transport roller, and the lifting carrier 62 and the lifting member 7 vertically pass through along the vertical direction in the spacing space 10.

[0054] Specifically, when the transport roller assembly 9 comprises a plurality of transport rollers, the plurality of transport rollers can be drivingly connected by arranging a transmission member, or a plurality of driving rollers are arranged, and the plurality of transport rollers are spaced apart and located above the fixed carrier 3. At this time, the spacing space 10 between the transport rollers is realized by lifting the lifting member 7, so as to lift the steel material 11 on the transport roller by the lifting member 7 and then weigh. After weighing, the lifting driving member 4 controls the lifting member 6 to fall back, and the steel material 11 falls on the transport roller assembly 9 again. The transport roller way transports the steel material 11 out of the weighing area, and waits for the next steel material 11 to be weighed. Thus, the steel material 11 being transported can be continuously weighed, and the weighing efficiency is improved.

[0055] The steps during weighing are described in detail below by taking the case of arranging the transport roller assembly 9 as an example.

[0056] Step a1: driving the lifting driving member 4 to be in a retracted state, the lifting member 6 is at the lowest position, and the weighing module 2 is in a waiting weighing state;

[0057] Step a2: the transport roller assembly 9 transports the steel material 11 to the weighing position (the position of the fixed carrier 3) and stops, so as to ensure that the steel material 11 can be completely lifted up;

[0058] Step a3: driving the lifting driving member 4 to be synchronously extended, and the lifting member 6 is synchronously lifted, so as to lift the steel material 11 to be separated from the surface of the transport roller of the transport roller assembly 9;

[0059] Step a4: driving the lifting driving member 4 to be completely extended, and the lifting member 6 (the lifting carrier 62) is lifted to the highest position and stopped, so that the weighing module 2 completes the square steel weight data reading (the weight of the fixed carrier 3 excluding the steel material 11 is generally known);

[0060] Step a5: driving the lifting driving member 4 to be synchronously retracted, and the lifting member 6 is synchronously lowered, so as to lower the steel material 11 to the surface of the transport roller of the transport roller assembly 9;

[0061] Step a6: driving the lifting driving member 4 to be completely retracted, and the lifting member 6 is lowered to the lowest position and stopped;

[0062] Step a7: the transport roller assembly 9 transports the steel material 11 out of the weighing area; waits for the next steel material 11 to be weighed.

[0063] Of course, if the transport roller assembly 9 is not provided, the step of transporting the steel material 11 can be omitted, and the steel material 11 can be directly placed on the lifting member 6 (of the lifting piece 7) by the lifting tool, and then hoisted after weighing.
