Description

Technical Field

[0001] This utility model belongs to the field of weighing equipment technology, and in particular relates to an industrial weighing scale. Background Technology

[0002] Industrial weighing scales typically employ a U-shaped platform design to facilitate forklift loading and unloading, with an open structure allowing forklifts to drive in and unload. To increase the flexibility of the U-shaped weighing scale, casters are installed at the bottom of the platform. However, this design has the following drawbacks in practical applications: Because the U-shaped platform is suspended due to the casters, excessive force on one side can occur when containers or goods shift, potentially leading to plastic deformation of the platform over time and affecting the equipment's lifespan.

[0003] Therefore, how to avoid plastic deformation of the weighing platform due to excessive force on one side of the U-shaped weighing scale is a technical problem that urgently needs to be solved by those skilled in the art.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0042] In this document, when it is mentioned that a first component is located on a second component, this can mean that the first component can be directly formed on the second component, or that a third component can be inserted between the first and second components. Furthermore, in the accompanying drawings, the thickness of the components may be exaggerated or reduced for the purpose of effectively describing the technical content.

[0043] In this document, when an element or layer is referred to as “located,” “joined to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly located, joined, connected, attached to, or coupled to the other element or layer, or there may be intermediate elements or layers present. Conversely, when an element is referred to as “directly on another element or layer,” “directly joined to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intermediate elements or layers present. Other terms used to describe relationships between elements should be interpreted in a similar manner (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items.

[0044] In this document, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as “at least one of…” modify the entire list of elements when following a list of elements, rather than individual elements in the list. For example, the expression “at least one of a, b, and c” should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0045] The terminology used herein is for the purpose of describing specific exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may also be intended to include plural forms unless otherwise clearly stated herein.

Therefore, a particular feature, structure, or characteristic can be included in more than one embodiment of this disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms “example,” “exemplary,” etc., are used to “serve as an example, instance, or illustration.” Any implementation, aspect, or design described herein as “example” or “exemplary” is not necessarily to be construed as preferred or superior to other implementations, aspects, or designs. Rather, the use of the terms “example,” “exemplary,” etc., is intended to present concepts in a specific manner.

[0047] Research has revealed the following drawbacks of existing technology: After installing pulleys at the bottom of the U-shaped industrial weighing scale platform, the platform is suspended in the air. When the ton containers or goods are placed off-center, the force on one side is too great, which may lead to plastic deformation of the platform after long-term use and affect the lifespan of the equipment.

[0048] Based on the above research, this disclosure provides an industrial weighing scale. By setting a support plate at the longitudinal symmetrical center line of the two weighing platforms, it can provide support and facilitate the centering of goods on the forklift, thus solving the above problems.

[0049] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0050] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0051] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0052] See Figure 1 This disclosure provides an industrial weighing scale, comprising: a pair of weighing platforms 100, each with at least two main rollers 110 at its bottom for easy movement of the weighing platform 100 to a target position. The two weighing platforms 100 are connected by a connecting plate 200 in the middle to form a U-shaped weighing body. A support plate 300 is vertically welded to the middle of the connecting plate 200, and auxiliary rollers 310 are provided at the bottom of the support plate 300. The top surface of the support plate 300 is on the same horizontal plane as the top surface of the weighing platform 100; and the central axis of the support plate 300 coincides with the longitudinal symmetrical center line of the two weighing platforms 100. The support plate 300 is adapted to distribute the pressure on the two weighing platforms 100 when the goods are placed off-center. A forklift can be aligned with the support plate 300 through the gap in the middle to facilitate the centering of the goods on the forklift and to place them evenly on the two weighing platforms 100, thereby avoiding plastic deformation of the weighing platform 100 due to excessive force on one side of the U-shaped industrial weighing scale.

[0053] See also Figure 1 In some embodiments, triangular reinforcing ribs 320 are provided between the two sides of the support plate 300 and the connecting plate 200. The triangular reinforcing ribs 320 can enhance the lateral stiffness of the support plate 300 and improve its stability.

[0054] See Figure 1 and Figure 5 In some embodiments, the industrial weighing scale further includes a control box 400, with a warning light 410 mounted on its top, and a control module housed within the control box 400. A weighing sensor is installed within the weighing platform 100, and both the weighing sensor and the warning light 410 are electrically connected to the control module. The control module is configured to activate the warning light 410 when the weighing sensor on one side of the weighing platform 100 detects a weight exceeding a set threshold. When the warning light 410 is activated, the operator can promptly stop adding material to the bin, preventing excessive weight from being borne by one side of the weighing platform 100.

[0055] See Figure 2 and Figure 5 In some embodiments, the bottom of the weighing platform 100 is also provided with several hydraulic support legs 500, and the hydraulic cylinders 510 of the hydraulic support legs 500 are electrically connected to the control module; the control module is also configured to: when a single-sided weighing sensor detects that the weight is greater than a set threshold, control the hydraulic cylinder 510 to extend the hydraulic support legs 500 to support the weighing platform 100 and prevent it from undergoing plastic deformation.

[0056] See Figure 3 and Figure 4Some embodiments also provide an industrial weighing scale, including: two symmetrically arranged weighing platforms 100, each with at least two main rollers 110 at its bottom; a connecting plate 200, with its two ends connected to the two weighing platforms 100 respectively; a support plate 300, vertically mounted in the middle of the connecting plate 200, with a support foot 330 hinged to its bottom; and a permanent magnet block 340 provided at the bottom of the support plate 300 for limiting the support foot 330. When the industrial weighing scale needs to be moved, the support foot 330 is parallel to the support plate 300 and is attracted by the permanent magnet block 340; the top surface of the support plate 300 is on the same horizontal plane as the top surface of the weighing platform 100; and the central axis of the support plate 300 coincides with the longitudinal symmetrical center line of the two weighing platforms 100. When the industrial weighing scale is in operation, the operator rotates the support foot 330, causing it to rotate away from the permanent magnet block 340 around the hinge point until the support foot 330 is perpendicular to the support plate 300, thus providing support.

[0057] As one specific implementation method, the load cell can be, but is not limited to, an HBM RTNC3 torsion ring load cell, and the control module is a PLC (Siemens S7-1200). The HBM RTNC3 torsion ring load cell is connected to the RTN / M weighing module, and then the RTN / M weighing module is connected to the PLC.

[0058] The method of turning on the warning light 410 by the control module according to the weighing signal involved in this embodiment is all existing technology, and this embodiment does not make any substantial improvement to the above method.

[0059] In summary, this industrial weighing scale has a support plate 300 on the connecting plate 200 to distribute the pressure between the two weighing platforms 100. At the same time, the central axis of the support plate 300 coincides with the longitudinal symmetrical center line of the two weighing platforms 100. By aligning the support plate 300 with the gap in the middle of the forklift, it is easy to center the goods on the forklift and place them evenly on the two weighing platforms 100, thereby avoiding plastic deformation of the weighing platform 100 due to excessive force on one side of the U-shaped industrial weighing scale.

[0060] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0061] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0062] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0063] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0064] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
