Description

Technical Field

[0001] The utility model belongs to the field of weighing sensors and relates to a weighing module with adjustable height. Background Art

[0002] Load cells operate primarily based on the strain gauge principle. When an object is placed on the sensor, its gravity causes the elastic element within the sensor to deform. This deformation is sensed by a strain gauge attached to the elastic element, causing a change in the gauge's resistance. Through a specific circuit, this change in resistance is converted into an electrical signal proportional to the weight of the object being measured.

[0003] In industries such as fine chemicals, new energy lithium batteries, and animal husbandry, load cells are often used for weighing measurements. However, after on-site construction, the height of the weighed objects is often difficult to adjust. The industry generally uses an upper bearing plate, a lower bearing plate, and a spherical force transmission structure to form a weighing module. The upper bearing plate transmits force to the load cell through the force transmission structure, achieving the desired weighing result. Once installed on-site, the weighing module becomes integrated with the on-site equipment (such as silos and reactors), making height adjustment difficult. Utility Model Content

[0004] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a weighing module with adjustable height, which can realize free height adjustment after on-site installation and in working state.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

The fixed end of the sensor is connected to the support frame, and the loading end extends out of the support frame. The connecting plate is connected to the loading end of the sensor with a bolt. The bottom of the bolt is threaded with a height adjustment nut. There is a gap between the top of the connecting plate and the bottom of the sensor loading end, and there is a gap between the bottom of the connecting plate and the top of the base plate.

[0008] Preferably, mounting holes are provided at the four corners of the base plate.

[0028] like Figure 1 and Figure 2 As shown, the height-adjustable weighing module described in the present invention is suitable for weighing modules with smaller ranges, and includes a base 1, a pad 2, a sensor 3, a sensor mounting bolt 4, a pressure-bearing bolt 5, a height-adjusting nut 6, a connecting plate 7, and an assembly bolt 8.

[0029] like Figure 2 As shown, the base 1 of this weighing module includes two parts: a base plate and a support frame. The support frame is located on the top of the base plate. The base plate and the support frame are welded and fixed. The base plate is placed horizontally on the on-site foundation and is fixed to the on-site foundation by four bolts. In this embodiment, four waist-shaped holes are designed on the base plate, which are located at the four corners of the base plate for connecting to the foundation through expansion bolts or anchor bolts.

[0030] The support frame includes two vertical plates and a crossbeam. The two vertical plates are vertically arranged on the bottom plate, the two vertical plates are spaced apart, the tops of the two vertical plates are connected by a crossbeam, and reinforcing ribs are arranged between the sides of the two vertical plates and the bottom plate to improve the bearing capacity of the support frame.

[0031] In this embodiment, sensor 3 utilizes a shear beam load cell. Shear beam load cells, also known as cantilever beam load cells, operate based on the strain gauge principle. When an object is placed on the sensor, its gravity causes the elastic element (typically an I-shaped cross-section) within the sensor to deform. This deformation is converted into shear force, which in turn causes a change in the resistance of the strain gauge on the elastic element. Through a specific circuit, this change in resistance is converted into an electrical signal output whose magnitude is proportional to the weight of the object being measured.

[0032] The fixed end of the sensor 3 is mounted on the base 1 through the sensor mounting bolts 4 and the pad 2. Specifically, the top of the fixed end of the sensor 3 is located at the bottom of the beam, the loading end of the sensor 3 extends out of the beam, and the pad 2 is located at the bottom of the fixed end of the sensor 3. The pad 2, the fixed end of the sensor 3 and the beam are connected by the sensor mounting bolts 4. In this embodiment, there are two sensor mounting bolts 4, which increases the reliability of the fixation and can limit the sensor 3 to prevent the sensor 3 from rotating and causing measurement errors.

[0033] The connecting plate 7 is a welded structural part with a C-shaped structure. The connecting plate 7 is connected to the sensor 3 through a pressure-bearing bolt 5. The pressure-bearing bolt 5 vertically passes through the loading end of the sensor 3 and the top of the connecting plate 7. The top of the pressure-bearing bolt 5 is located at the top of the loading end of the sensor 3, and the bottom of the pressure-bearing bolt 5 is located in the C-shaped notch of the connecting plate 7. The bottom of the pressure-bearing bolt 5 is threadedly connected with a height adjustment nut 6. After the connecting plate 7 is connected to the sensor 3, the connecting plate 7 is lifted by the height adjustment nut 6. The weight of the connecting plate 7 is pressed on the height adjustment nut 6. There is a gap between the top of the connecting plate 7 and the bottom of the loading end of the sensor 3, and there is a gap between the bottom of the connecting plate 7 and the top of the base plate.

[0034] At least one assembly hole is provided on the side of the connecting plate 7. In this embodiment, there are three assembly holes, and the three assembly holes are arranged vertically at intervals to ensure that the connection between the connecting plate 7 and the object to be weighed is reliable. The object to be weighed is connected to the assembly hole through the assembly bolt 8 and connected to the connecting plate 7. For example, the tank legs are connected to the connecting plate 7 through the assembly bolt 8.

[0035] The use process of the height-adjustable weighing module described in this embodiment is as follows: after the weighing object is connected to the connecting plate 7 through the assembly bolts 8, the height adjustment nut 6 is screwed up and down to change the position of the height adjustment nut 6 on the pressure-bearing bolt 5, thereby adjusting the height of the connecting plate 7 and achieving free height adjustment.
