Description

Technical Field

[0001] This utility model belongs to the field of weighing technology, specifically relating to a weighing platform module and a truck scale. Background Technology

[0002] A truck scale is a large weighing platform set on the ground, usually used to weigh the tonnage of a truck's cargo. It is the main weighing equipment used for measuring bulk goods.

[0003] The weighing accuracy of a truck scale is closely related to its structural stability. Existing truck scales are mainly divided into single-platform truck scales and multi-platform truck scales. A single-platform truck scale carries the weight of a truck through a single platform module, while a multi-platform truck scale carries the weight of a truck through multiple interconnected platform modules.

[0004] Existing weighing platform modules mainly consist of a platform panel, end plates, and support components. The end plates are roughly vertically positioned at the bottom of the platform panel, while the support components are fixed to the platform panel and directly or indirectly connected to the load cells, providing a stable load-bearing foundation for the load cells. Existing support components are primarily formed by assembling multiple metal plates and connectors to meet load-bearing and assembly requirements. However, this assembly structure of the support components has the following significant drawbacks in actual production and application.

[0005] Firstly, the spliced ​​structure is composed of multiple independent parts, resulting in poor overall structural strength. Since the area near the support is a stress concentration zone, the support often experiences bending deformation or cracking.

[0006] Secondly, the large number of parts in the splicing structure increases the complexity of the structural design, making it more difficult to process, procure and manage the parts. In addition, the large number of parts also leads to a large workload in splicing, requiring more labor and time costs, which further increases the overall production and manufacturing costs.

[0007] Third, the splicing structure involves the processing of multiple parts. Each part needs to go through multiple processes such as cutting, stamping, and machining. After the parts are processed, they need to be spliced ​​and assembled one by one. After splicing, subsequent processing processes such as grinding, flaw detection, and stress relief are also required. The process of each step is complicated and interconnected. Delay in any step may affect the overall production progress and lead to an extension of the product production cycle.

[0008] Fourth, the structure is not compact enough. Due to its own structural characteristics, the splicing structure requires a certain gap and assembly allowance between each part, resulting in a large overall structural size and insufficient compactness. This makes it less adaptable to space-constrained application scenarios.

[0009] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0041] Example 1

[0042] Reference Figures 1 to 5 As shown, one embodiment of the present invention provides a weighing platform module 100, which includes a weighing platform panel 110, an end plate 120, a support member 130, and a load-bearing beam 140.

[0043] Specifically, the weighing platform 110 is used to support the vehicle to be weighed. Two end plates 120 are provided, arranged substantially parallel to each other and located at the bottom of the weighing platform 110. One end plate 120 is positioned adjacent to one edge of the weighing platform 110, and the other end plate 120 is positioned adjacent to the other edge of the weighing platform 110. The end plates 120 are substantially perpendicular to the weighing platform 110, and their tops are fixedly connected to the weighing platform 110 by welding. Support members 130 are used to be mounted on the load cell 400 to transfer the weight of the vehicle to be weighed to the load cell 400. Four support members 130 are provided, with two support members 130 positioned along the length of one end plate 120 on its side, and the other two support members 130 positioned along the length of the other end plate 120 on its side. The support member 130 is fixedly connected to the end plate 120 by welding, and the top of the support member 130 is connected to the weighing platform panel 110 by welding. The load-bearing beam 140 is fixed to the bottom of the weighing platform panel 110 by welding. The load-bearing beam 140 extends along the thickness direction of the end plate 120 and is connected to the end plates 120 on both sides by welding. The load-bearing beam 140 includes two end load-bearing beams 141 and several intermediate load-bearing beams 142, with the intermediate load-bearing beams 142 located between the two end load-bearing beams 141. In addition to being connected to the end plate 120, the end load-bearing beams 141 are also connected to their adjacent support members 130 by welding.

[0044] According to the above structural design, any two of the weighing platform panel 110, end plate 120, support member 130, and load-bearing beam 140 are fixedly connected together by welding. A weld is formed at the connection point of any two components, making the weighing platform module 100 a single, integrated structure to bear the weight of the vehicle to be weighed. Compared to a traditional weighing platform module 100, the weighing platform module 100 in this embodiment has a more compact structure, eliminating gaps and misalignments at the connections of various components, and ensuring sufficient structural stability of the weighing platform module 100 during long-term use.

[0045] Furthermore, the connection between the weighing platform module 100 and the load cell 400 is susceptible to impact from vehicles entering and leaving the weighing platform, making this connection area the region of highest stress concentration. In this embodiment, the weighing platform module 100 forms a robust connection structure at the aforementioned connection point, consisting of an end plate 120, a support member 130, and a load-bearing beam 140. This structure can quickly transfer the impact force from the vehicles to the load cell 400, reducing the probability of deformation and cracking of the components at the connection point between the weighing platform module 100 and the load cell 400 due to stress concentration.

[0046] Reference Figure 4 and Figure 5 As shown, the support member 130 includes a plate portion 131 and a platform portion 132. The plate portion 131 is generally parallel to the end plate 120 and is welded to the end plate 120. The platform portion 132 protrudes generally along the thickness direction of the support member 130. The platform portion 132 is specifically located on the side of the plate portion 131 away from the load-bearing beam 140 and extends in a direction away from the load-bearing beam 140. The platform portion 132 is used for overlapping with other weighing platform modules.

[0047] Furthermore, a clearance groove is formed at the bottom of the support member 130, and a mounting hole is provided on the top wall of the clearance groove. The mounting hole is used to connect to the load cell 400, and can be plugged into the corresponding part of the load cell 400. The design of the platform part 132 is equivalent to locally thickening the most critical stress points of the support member 130 (i.e., the connection between the platform part 132 and the load cell 400, and the load-bearing part that supports other weighing platform modules), rather than thickening the support member 130 as a whole. This not only optimizes the structural strength of the support member 130 at the most critical stress points, but also saves material consumption. Moreover, compared with the traditional overall thickening design, the local thickening design of the platform part 132 can also make the support member 130 lighter, making it easier to transport, install and maintain.

[0048] In general, to ensure the connection strength between the end plate 120 and the support member 130, a portion of the plate 131 is fitted to the surface of the end plate 120, and then the periphery of the fitted area is welded to fix them together. However, with this connection method, the cantilever distance of the support member 130 (i.e., the vertical distance between the central axis of the mounting hole and the end plate 120) is relatively large. This results in significant stress concentration at the welds where the support member 130 connects to the weighing platform panel 110, the end plate 120, and the load-bearing beam 140. The welds in the stress concentration areas are prone to cracking, reducing the structural strength of the weighing platform module 100.

[0049] Therefore, refer to Figure 4 , Figure 5 and Figure 7 As shown, in order to reduce the cantilever distance of the support member 130, a clearance structure is provided on the support member 130 to appropriately reduce the thickness at the connection between the end plate 120 and the support member 130.

[0050] Specifically, the support member 130 includes a plate portion 131 connected to the end plate 120. The plate portion 131 includes a thick plate segment 1311 and a thin plate segment 1312 arranged along the direction close to the end plate 120. The thickness of the thick plate segment 1311 is greater than the thickness of the thin plate segment 1312. The surfaces of the thick plate segment 1311 and the thin plate segment 1312 are flush on the side away from the load-bearing beam 140. The thick plate segment 1311 is connected to the end of the end plate 120, and the thin plate segment 1312 extends from the end of the thick plate segment 1311 to the side of the end plate 120 away from the load-bearing beam 140, and is in contact with and connected to the surface of the end plate 120. The thin plate segment 1312 of the support member 130 can appropriately reduce the thickness at the connection between the end plate 120 and the support member 130, reduce the distance between the mounting hole at the bottom of the support member 130 and the end plate 120, thereby reducing the cantilever distance of the support member 130 and improving the overall structural strength and stability of the weighing platform module 100.

[0051] Furthermore, at the connection between the end plate 120 and the support member 130, the sum of the thicknesses of the end plate 120 and the thin plate segment 1312 is approximately equal to the thickness of the thick plate segment 1311. After the end plate 120 and the support member 130 are welded together, the surfaces of the end plate 120 and the support member 130 on the side near the load-bearing beam 140 can remain approximately flush, facilitating the simultaneous welding of the load-bearing beam 140 to both the end plate 120 and the support member 130.

[0052] Reference Figure 4 As shown, the end plate 120 and the thick plate section 1311 are connected together by welding, and a first weld 160 is formed between the thin plate section 131 and the thick plate section 1311. The end plate 120 and the thin plate section 1312 are also connected together by welding, and a second weld 170 is formed between the thin plate section 131 and the thin plate section 1312.

[0053] The first weld 160 is formed between the end of the end plate 120 and the end of the thick plate segment 1311, and also connects the thin plate segment 1312 on the surface between the two ends. The second weld 170 is formed at the end of the thin plate segment 1312 away from the thick plate segment 1311, and also forms on the surface of the end plate 120. The double weld structure formed by the first weld 160 and the second weld 170 can improve the connection strength between the support member 130 and the end plate 120, and can distribute the load more evenly when the weighing platform module 100 is under stress, enhance the shear resistance, tensile resistance and fatigue resistance of the connection between the support member 130 and the end plate 120, and improve the ability of the weighing platform module 100 to withstand dynamic loads or impact loads.

[0054] Furthermore, the connection between the end plate 120 and the plate portion 131 of the support member 130 is inclined, and the first weld 160 and the second weld 170 formed at the connection are also inclined along the corresponding inclined edges of the end plate 120 and the plate portion 131. The inclination direction and inclination angle of the first weld 160 and the second weld 170 are approximately the same, and the inclination direction of the first weld 160 and the second weld 170 satisfies the following: the horizontal distance between the top of the first weld 160 and the center of the end plate 120 is greater than the horizontal distance between its bottom and the center of the end plate 120, and the horizontal distance between the top of the second weld 170 and the center of the end plate 120 is greater than the horizontal distance between its bottom and the center of the end plate 120.

[0055] After the first weld 160 and the second weld 170 are set in the above-mentioned inclined manner, the force borne at the connection between the end plate 120 and the support member 130 can be converted into internal stress that makes the two end plates 120 and the support member 130 fit tightly together, thereby reducing stress concentration at the weld and improving the fatigue life and reliability of the weld.

[0056] Reference Figure 3 As shown, a cavity is formed inside the end bearing beam 141. On a plane perpendicular to the length direction of the end bearing beam 141, the vertical projection of at least one weld between the support member 130 and the end plate 120 intersects the vertical projection of the cavity. Alternatively, it can be understood that at least one weld between the support member 130 and the end plate 120 is located within the aforementioned cavity.

[0057] The end bearing beam 141 and the intermediate bearing beam 142 have similar structures, both being U-shaped beams. The end bearing beam 141 includes a first plate 143 and a second plate 144 arranged opposite each other along its width, and a third plate 145 connected to the bottom of the first plate 143 and the bottom of the second plate 144. The first plate 143, the second plate 144, and the third plate 145 together form the aforementioned cavity. The cross-section of the end bearing beam 141 is similar to an isosceles trapezoid, with the first plate 143 and the second plate 144 corresponding to the two legs of the trapezoid.

[0058] When the end bearing beam 141 is connected to the end plate 120 and the support member 130, the first plate 143 is welded to the end plate 120, the first plate 143 is welded to the plate portion 131 of the support member 130, the area of ​​the third plate 145 near the first plate 143 is welded to the end plate 120, the area of ​​the third plate 145 near the second plate 144 is welded to the plate portion 131 of the support member 130, and the first weld 160 is located between the first plate 143 and the second plate 144 in the length direction of the end plate 120.

[0059] Most of the area of ​​the first weld 160 is covered by the end bearing beam 141, which puts it in a relatively closed space. This prevents external moisture, dust and other media from seeping into the first weld 160 through the pores, cracks or incompletely fused areas inside the first weld 160, reducing the probability of corrosion of the first weld 160 and improving the overall structural stability and service life of the weighing platform module 100.

[0060] Reference Figure 4 and Figure 5 As shown, a lifting hole 135 is provided on the plate portion 131 of the support member 130. Preferably, the lifting hole 135 can be provided on the thick plate section 1311 of the plate portion 131. When lifting the weighing platform module 100, the stress concentration at the contact point between the support member 130 and the hook can be reduced, and the probability of deformation or damage to the lifting hole 135 can be reduced.

[0061] Reference Figure 4 and Figure 5 As shown, a first limiting part 133 and a second limiting part 134 are formed on the support member 130. Both the first limiting part 133 and the second limiting part 134 protrude upward from the platform part 132. The first limiting part 133 is disposed opposite to the plate part 131. The second limiting part 134 connects the plate part 131 and the first limiting part 133 and is located on the side of the first limiting part 133 away from the end plate 120.

[0062] A first limiting surface is formed on the side of the plate portion 131 near the first limiting portion 133, and a second limiting surface is formed on the side of the first limiting portion 133 near the plate portion 131. The first and second limiting surfaces are positioned opposite each other along the thickness direction of the support member 130. A third limiting surface is formed on the side of the second limiting portion 134 near the end. The first, second, and third limiting surfaces together form a limiting space. When the overlapping structure of other weighing platform modules is located in the aforementioned limiting space, the overlapping structure can be limited to move in the opposite direction of the thickness and length of the support member 130 (the length direction is parallel to the length direction of the end plate 120), ensuring that the overlapping structure of other weighing platform modules can be stably overlapped on the platform portion 132 of the support member 130, so that all weighing platform modules 100 can jointly bear the vehicle to be weighed.

[0063] It should be noted that the weighing platform module 100 in this embodiment can be applied to single-platform, double-platform, triple-platform, and truck scales with more platforms. When the weighing platform module 100 in this embodiment is applied to a single-platform truck scale, it can be used as the entire weighing platform without the need to connect other weighing platform modules. When the weighing platform module 100 in this embodiment is applied to double-platform, triple-platform, and truck scales with more platforms, the connecting structures of other weighing platform modules can be connected to the platform portion 132 of the support member 130.

[0064] Furthermore, the connection between any two of the weighing platform panel 110, end plate 120, support member 130 and load-bearing beam 140 is not limited to welding; these components can also be connected by bolts, riveting, or other methods.

[0065] In addition, the support member 130 can be set as a one-piece metal casting structure, or it can be formed in one piece by machining or forging.

[0066] Furthermore, the statement that "the support member 130 is disposed along the length of the end plate 120 on the side of the end plate 120" does not mean that the end plate 120 and the support member 130 are arranged strictly along the length of the end plate 120, but rather that the position of the support member 130 is approximately adjacent to the end region of the end plate 120 in the length direction. In the aforementioned end region of the end plate 120, the support member 130 can be wholly or partially connected to the side of the end plate 120 facing away from the load-bearing beam 140, and this connection method between the end plate 120 and the support member 130 should also be considered within the scope of protection of this application.

[0067] In other embodiments, the end plate 120 and the support member 130 can also be configured as a single integral structure, which can also be integrally formed using casting, forging, or additive manufacturing processes. In this embodiment, after the end plate 120 and support member 130 are combined with the weighing platform panel 110 and the load-bearing beam 140, the overall structural strength is significantly higher than that of traditional weighing platform modules. Furthermore, it can also reduce the stress concentration around the support member 130, reducing the probability of bending deformation or fatigue damage to the support member 130 and its surrounding components.

[0068] Example 2

[0069] Reference Figure 6 and Figure 7 As shown, an embodiment of the present invention provides a weighing platform module 100. The difference between this weighing platform module 100 and embodiment 1 is that the weighing platform module 100 in this embodiment includes two support members 130 and two overlapping members 150. The overlapping members 150 are fixedly connected to the end plate 120 by welding. When the overlapping members 150 are welded to the end plate 120, one side surface of the overlapping member 150 can be attached to the end plate 120, and the edge of the overlapping member 150 is welded to form a weld seam at the edge of the overlapping member 150.

[0070] In this embodiment, the support member 130 is also used to connect to the weighing sensor 400, while the overlapping member 150 is used to overlap to the support member 130 of Embodiment 1 or the support structure of other weighing platform modules.

[0071] Specifically, in this embodiment, the two support members 130 of the weighing platform module 100 are distributed at two adjacent corners of the weighing platform panel 110, and the two overlapping members 150 are distributed at the other two corners of the weighing platform panel 110. When the weighing platform module 100 of this embodiment overlaps with the weighing platform module 100 of embodiment 1, the two overlapping members 150 of the weighing platform module 100 of this embodiment are located on the side closer to the weighing platform module 100 of embodiment 1, and overlap with two of the support members 130 of embodiment 1 in a one-to-one correspondence. The two support members 130 of the weighing platform module 100 of this embodiment are located on the side away from the weighing platform module 100 of embodiment 1, and are used to connect to the corresponding weighing sensor 400.

[0072] In addition, the two support members 130 of the weighing platform module 100 in this embodiment can also be used to connect with other weighing platform modules, and the structure of other weighing platform modules can adopt the structure of the weighing platform module 100 in this embodiment.

[0073] Reference Figure 8 and Figure 9As shown, in order to improve the stability of the overlap member 150 after it overlaps with the support member 130 and to limit the relative movement between the overlap member 150 and the support member 130, the overlap member 150 in this embodiment includes an overlap portion 151 and an extension portion 152. The overlap portion 151 overlaps on the platform portion 132 of the support member 130, and the extension portion 152 extends from the side of the overlap portion 151 near the second limiting portion 134 into the limiting space formed by the first limiting surface, the second limiting surface and the third limiting surface.

[0074] It should be noted that the lap joint 150 in this embodiment can be set as an integral metal casting structure, or it can be manufactured by machining or forging processes.

[0075] Example 3

[0076] Reference Figure 1 As shown, one embodiment of the present invention provides a truck scale, which is a single-platform truck scale. The truck scale includes the weighing platform module 100 and weighing sensors 400 as in Embodiment 1. The number of weighing sensors 400 is the same as the number of support members 130, and they are arranged one-to-one at the bottom of the support members 130.

[0077] Example 4

[0078] Reference Figure 6 and Figure 7 As shown, an embodiment of the present invention provides a truck scale. The difference between this embodiment and embodiment 3 is that the truck scale in this embodiment has two platforms.

[0079] Specifically, the truck scale in this embodiment includes a first weighing platform module 200 and a second weighing platform module 300. The first weighing platform module 200 adopts the weighing platform module 100 in Embodiment 1, and the second weighing platform module 300 adopts the weighing platform module 100 in Embodiment 2. The support member 130 of the second weighing platform module 300 is located on the side away from the first weighing platform module 200, and the overlapping member 150 of the second weighing platform module 300 is located on the side close to the first weighing platform module 200. The overlapping member 150 of the second weighing platform module 300 overlaps one-to-one with the support member 130 of the adjacent first weighing platform module 200.

[0080] Example 5

[0081] This utility model provides a truck scale in one embodiment. The difference between this embodiment and embodiment 3 is that the truck scale in this embodiment has three or more platforms.

[0082] Specifically, the truck scale in this embodiment includes a first weighing platform module 200 and at least two second weighing platform modules 300. The first weighing platform module 200 adopts the weighing platform module 100 in Embodiment 1, and the second weighing platform modules 300 adopt the weighing platform module 100 in Embodiment 2.

[0083] The first weighing platform module 200 can be arranged at one end, and the second weighing platform module 300 can be arranged on the same side of the first weighing platform module 200. Alternatively, the first weighing platform module 200 can be arranged in a region relatively close to the middle, and the second weighing platform modules 300 can be arranged on both sides of the first weighing platform module 200.

[0084] Furthermore, when two adjacent second weighing platform modules 300 overlap each other, at the point of overlap, the overlapping member 150 of one second weighing platform module 300 overlaps the support member 130 of the other second weighing platform module 300.

[0085] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0086] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
