Description

Technical Field

[0001] The utility model relates to the technical field of electronic scales, specifically a load weighing device in an electronic weighing system. Background Art

[0002] The existing publicly disclosed load weighing devices or weighing modules are basically composed of a weighing sensor, an upper fixing plate, a lower fixing plate, a supporting component and a fastening component for fixing the sensor. By connecting the upper fixing plate to the device to be weighed, such as a weighing tank body, etc., and connecting the lower fixing plate to the equipment foundation, the purpose of simplifying the on-site use and installation of the sensor as a whole is achieved.

[0003] The existing installation requirements for weighing modules are relatively complex. There are different installation forms in a set of devices, and corresponding requirements are imposed on the installation direction, installation position and installation sequence of the devices, making it difficult for customers to understand. In addition, some functions are lacking in some designed devices. Some devices are affected by the internal stirring force of the device to be weighed, as well as external forces such as environmental wind force and vibration, causing the sensor to be affected by horizontal force and vertical component force, resulting in relative position movement, bringing corresponding safety hazards and making it difficult to ensure weighing accuracy.

[0004] At the same time, at present, some devices use a limit structure as the protection structure of the module, but due to the single-point protection, it is easy to shift under the condition of large external force, resulting in inaccurate weighing data. Summary of the Utility Model

A cushion block is installed at the right end of the top of the single-point weighing sensor. An upper mounting plate welded assembly is installed on the top of the cushion block. Both ends of the bottom of the upper mounting plate welded assembly are connected to the lower mounting plate through stud bolts.

[0008] In a preferred embodiment of the utility model, the single-point weighing sensor and the cushion block are connected by high-strength bolts.

[0024] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0025] Please refer to Figures 1-5 , a load weighing device in an electronic weighing system, including a single-point weighing sensor 1. A weighing foot assembly 4 is installed at the left end of the bottom of the single-point weighing sensor 1. The bottom of the weighing foot assembly 4 is fixedly connected to a lower mounting plate 5. A spacer 2 is installed at the right end of the top of the single-point weighing sensor 1. An upper mounting plate group weldment 3 is installed on the top of the spacer 2. Both ends of the bottom of the upper mounting plate group weldment 3 are connected to the lower mounting plate 5 through stud bolts 6;

[0026] As an independent weighing assembly unit, when leaving the factory, the stud bolts pass through the mating holes of the upper mounting plate group weldment and the lower mounting plate, so that the single-point weighing sensor is not affected by external forces during the entire assembly, transportation, and on-site installation processes, and preferably protects the weighing sensor during each process and avoids damage to the sensor caused by lateral impact forces; this load weighing device can be integrally installed into the weighing system without any other installation accessories;

[0027] The single-point weighing sensor 1 and the spacer 2 are connected by high-strength bolts 7.

[0028] A groove is provided on the left side of the top of the lower mounting plate 5. The bottom of the weighing foot assembly 4 is inserted into the groove and fixedly installed on the lower mounting plate 5 through a bolt 8.

[0029] The bottom of the stud bolt 6 is fixedly connected to the lower mounting plate 5, and the top of the stud bolt 6 is fixedly connected to the upper mounting plate group weldment 3.

[0030] The working principle of the present utility model is as follows: After being installed in the weighing system, loosen the self-locking nut of the stud cooperating with the upper mounting plate welded assembly, and maintain a certain gap, then the single-point sensor starts to bear the load and is in the normal weighing state. The whole installation and use process is simple and convenient; after the single-point sensor bears the load, the upper mounting plate welded assembly is in a floating state and only bears vertical forces, which can make the weighing error of the weighing system small and the accuracy high; when the weighing system is subjected to horizontal impact force or overturning force, the cooperation between the stud and the upper mounting plate welded assembly and the lower mounting plate can ensure that the single-point sensor is not damaged by additional horizontal force or overturning force. When the external force is eliminated, through the restoring force generated by the single-point sensor and the spherical surface at the top of the weighing foot assembly, it returns to the initial vertical state, ensuring the long-term stability and high-precision requirements of the sensor and the safety of the entire weighing system; the bottom of the weighing foot assembly is a rubber-coated part, which can provide a certain buffering force to avoid the structural misalignment caused by sudden weight changes from affecting the weighing accuracy and extend the service life of the sensor; the weighing foot assembly is fastened to the lower mounting plate by bolts and can maintain a dynamic vertical state with the sensor to stabilize the weighing accuracy;

[0031] All the installation accessories of the load-bearing weighing device are fixedly installed on the lower mounting plate. When the device needs to be maintained or the sensor needs to be replaced, only need to lift the equipment until the single-point weighing sensor is separated from the weighing foot assembly, then the sensor can be disassembled and replaced, and the device can still maintain its original installation state until the sensor replacement is completed.

[0032] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
