[0039] In an embodiment, refer to Figures 1 to 4As shown, the embodiment provides a U-shaped scale with a fixed frame, which comprises a U-shaped scale body 1, a fixed frame 2, four weighing modules 3 and four limiting modules 4. The U-shaped scale body 1 comprises two scale bodies 11 and a connecting portion 12, the two scale bodies 11 are oppositely arranged and parallel to each other, and the connecting portion 12 is located between the two scale bodies 11 and connects the two scale bodies 11, which together form a U-shaped scale body 1 similar to a U-shaped. The fixed frame 2 comprises two first frames 21, a second frame 22 and a third frame 23, the two first frames 21 are correspondingly arranged below the two scale bodies 11, the second frame 22 and the third frame 23 are arranged between the two first frames 21, and both of them are connected to the two first frames 21 at the same time, wherein the third frame 23 is detachably connected with the two first frames 21, and the third frame 23 is arranged relatively far away from the connecting portion 12, that is, the distance between the third frame 23 and the connecting portion 12 is greater than the distance between the second frame 22 and the connecting portion 12. The four weighing modules 3 are connected between the two scale bodies 11 and the two first frames 21, for supporting the two movable scale bodies 11. The plurality of limiting modules 4 are installed on the fixed frame 2 and are correspondingly arranged with the four weighing modules 3, for limiting the horizontal displacement of the weighing module 3 and simultaneously limiting the horizontal displacement of the U-shaped scale body 1.

[0040] According to the above structure design, the fixed frame 2 is constructed as a square hollow structure, compared with the traditional U-shaped frame structure, the structural strength of each part is obviously improved, it is relatively not easy to deform during transportation and installation, the support effect of the U-shaped scale body 1 is better, and the weighing precision is higher. Compared with the traditional square frame structure, the production cost of the square hollow structure of the fixed frame 2 is lower.

[0041] And in actual application, after the U-shaped scale is transported to the work site, the user can fix the fixed frame 2 on the ground or other supports by means of bolt fixing and the like, and then disassemble the third frame 23, so as to avoid the third frame 23 from hindering the movement of forklifts and other handling equipment, and prevent the fork arms of the forklifts or the bottom mechanical structures of other handling equipment from touching the third frame 23.

[0042] In an embodiment, referring to Figure 3 and Figure 4 As shown, the first frame 21 comprises two base plates 211 and a cross beam 212, the two base plates 211 are arranged in a spaced manner along the extension direction of the scale body 11, and the cross beam 212 is arranged between the two base plates 211 and simultaneously connects the two base plates 211, and the weighing module 3 is connected to the scale body 11 and the two base plates 211 below the scale body 11.

[0043] Further, the two ends of the cross beam 212 are fixedly connected with the two base plates 211, and the connection mode of connecting the cross beam 212 and the base plate 211 includes but is not limited to welding, bolt connection and integral molding.

[0044] The crossbeam 212 may be made of angle steel, and its cross-sectional shape is approximately L-shaped. Alternatively, in other alternative embodiments, the crossbeam 212 may also be constructed as a plate structure.

[0045] In one embodiment, reference is made to Figure 4 and Figure 5 As shown, both the second frame 22 and the third frame 23 are constructed as plate structures. The second frame 22 is fixedly connected to the substrate 211 on the first side of the two first frames 21, and the third frame 23 is detachably connected to the substrate 211 on the second side of the two first frames 21. Specifically, connecting bolts 25 can be used to connect the third frame 23 to the corresponding substrate 211 of the two first frames 21.

[0046] Furthermore, when the cross-sectional shapes of the second frame 22 and the third frame 23 are designed differently from the cross-sectional shape of the beam 212, they can work together to form a foolproof structure, assisting installers in installation and positioning, and reducing the probability of incorrect assembly.

[0047] In one embodiment, reference is made to Figure 5 As shown, a threaded hole is provided on the substrate 211, which runs vertically through it. After a bolt is installed in the threaded hole, the bolt is screwed into the interior of the support body, which can firmly fix the substrate 211 to the support body. The support body includes, but is not limited to, the ground, a platform-like support structure, or other structures that can stably support the U-shaped scale.

[0048] Preferably, an expansion bolt 24 can be fitted into the threaded hole of the substrate 211.

[0049] In one embodiment, reference is made to Figure 6 and Figure 7 As shown, the weighing module 3 includes a load cell 31, a connecting base 32, and a pivot 33. The load cell 31 is bolted to the scale body 11, specifically mounted on the part of the scale body 11 facing the base plate 211. The connecting base 32 is mounted on the base plate 211 of the first frame 21 and is located below the load cell 31. The top end of the pivot 33 is inserted into the mounting hole at the bottom of the load cell 31 and is movably engaged with the load cell 31, while the bottom end of the pivot 33 is inserted into the mounting hole at the top of the connecting base 32 and is movably engaged with the connecting base 32.

[0050] Furthermore, the limiting module 4 includes two limiting posts 41 extending in the vertical direction, with the two limiting posts 41 respectively located on the adjacent sides of the weighing sensor 31.

[0051] Specifically, the four weighing sensors 31 of the four weighing modules 3 are arranged in a rectangular shape. Each weighing sensor 31 has two adjacent weighing sensors 31. Each weighing sensor 31 includes a first side and a second side located on its outer periphery and adjacent to each other. The first side faces away from one of the weighing sensors 31 adjacent to it, and the second side faces away from the other weighing sensor 31 adjacent to it. Two limiting posts 41 are respectively set close to the first side and the second side of the weighing sensor 31 and maintain a certain horizontal distance from the first side and the second side. That is, the weighing sensors 31 and the limiting modules 4 are set at intervals in the horizontal direction, leaving a certain amount of room for movement for the weighing sensors 31.

[0052] In one embodiment, reference is made to Figure 6 and Figure 7 As shown, the outer periphery of the main body 321 of the connecting seat 32 protrudes beyond the outer periphery of the weighing sensor 31. To avoid the protruding part of the main body 321, the limiting post 41 of the limiting module 4 has been designed differently in the vertical direction.

[0053] Specifically, the limiting post 41 includes a large-diameter section 411, a medium-diameter section 412, and a small-diameter section 413 arranged coaxially from top to bottom. The cross-sectional shapes of the large-diameter section 411, medium-diameter section 412, and small-diameter section 413 are all circular, with their cross-sectional diameters decreasing sequentially from bottom to top. The small-diameter section 413 is substantially completely inserted into the base plate 211 of the first frame 21 and is fixedly connected to the base plate 211 by welding. The medium-diameter section 412 extends upward from the top of the small-diameter section 413, ensuring that its top height is at least greater than the top height of the main body 321 of the connecting seat 32, and is spaced apart from the main body 321. The large-diameter section 411 extends upward from the top of the medium-diameter section 412, ensuring that its top height is at least greater than the bottom height of the load cell 31, and is spaced apart from the load cell 31.

[0054] Furthermore, the outer periphery of the cylindrical large-diameter section 411 forms a convex arc surface. When the load cell 31 contacts this arc surface, the contact method is either line contact or point contact. Compared with traditional planar limiting, the arc surface is easier to process and has relatively higher processing accuracy, which can improve the limiting accuracy of the limiting post 41.

[0055] Furthermore, the cross-sectional diameter of the large-diameter section 411 can be set between 30 and 34 mm, specifically 30 mm, 31 mm, 32 mm, 33 mm or 34 mm.

[0056] The cross-sectional diameter of the middle diameter section 412 can be set between 18 and 22 mm, specifically 18 mm, 19 mm, 20 mm, 21 mm or 22 mm.

[0057] The distance between the large diameter section 411 and the load cell 31 can be set between 1.5 and 2.5 mm, specifically 1.5 mm, 1.8 mm, 2 mm, 2.2 mm or 2.5 mm.

[0058] In other alternative embodiments, when the cross-sectional shape of the large diameter section 411 is constructed to be an irregular shape, an arc surface with a certain area and protruding toward the weighing sensor 31 can also be formed on the side of the large diameter section 411 near the weighing sensor 31 by means of machine tool processing or other methods.

[0059] In other alternative embodiments, if the requirement for the limiting accuracy of the limiting post 41 is not high, the cross-sectional shape of the large diameter section 411 can be set to a rectangular shape or the like, and the weighing sensor 31 can be limited by a planar limiting method.

[0060] In one embodiment, reference is made to Figure 1 As shown, the U-shaped scale also includes a data display device 5, which includes, but is not limited to, an instrument and a display screen. The weighing sensor 31 of the weighing module 3 is a digital sensor, and the weighing sensor 31 is directly electrically connected to the data display device 5 via a cable, eliminating the need for a junction box between the two.

[0061] In other alternative embodiments, when a non-digital high-precision sensor is selected for the weighing sensor 31, a junction box needs to be configured between the weighing sensor 31 and the data display device 5.

[0062] It should also be noted that the number of weighing module 3 and limiting module 4 in the above embodiments is a conventional choice in actual applications. For those skilled in the art, adaptive adjustments to the number of weighing module 3 and limiting module 4 without departing from the technical principles of this application should also be considered within the scope of protection of this application.

[0063] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0064] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification 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.
