Description

TECHNICAL FIELD

[0001] The utility model belongs to weighing technical field, concretely relates to a fixed frame and weighing system. BACKGROUND

[0002] In the weighing field, the fixed frame fixed on the ground or other bearing structure is usually used to bear the scale platform. When the scale platform needs to be leveled, the shims are usually placed at the bottom of the base of the fixed frame to adjust the height of the corresponding part of the fixed frame, so as to level the scale platform.

[0003] The base of the fixed frame is usually fixed on the ground or other bearing structure by bolts, and the side plate for limiting and protecting the scale platform and the weighing sensor is arranged on the base. When the scale platform is installed on the fixed frame, the bolts on the base are shielded by the side plate of the base and the scale platform, and the position of the bolts is relatively concealed.

[0004] When the shims need to be placed at the bottom of the base, the scale platform must be lifted upwards to expose the bolts on the base, and the operator can loosen the bolts to place the shims at the bottom of the base. Since the height of the base needs to be adjusted several times during the entire leveling process of the scale platform to achieve the best leveling effect, the scale platform needs to be repeatedly lifted, which makes the leveling work of the scale platform extremely tedious.

DETAILED DESCRIPTION

[0034] In order to make the person skilled in the art better understand the technical scheme in the present application, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the present application.

[0035] In the description of the present application, it should be understood that the orientation or position relationship indicated by the terms "top", "bottom", "upper", "lower" and the like is the orientation or position relationship based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0036] The terms "first", "second", "third", etc. are used only for descriptive purposes and should not be construed as implying or suggesting relative importance or an indicated number of technical features. Thus, features defined with "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly specified.

[0037] The embodiments of the present application expect to form a avoiding space for the torque applying tool on the base by improving the structure of the through hole and the side plate, so that the torque applying tool contacts the bolt of the fixed base through the avoiding space without disassembling the scale platform, and the leveling efficiency of the scale platform is improved.

[0038] Based on the above idea, in an embodiment, referring to Figures 1 to 3 The present application provides a fixed frame for carrying a scale platform, which comprises a plurality of bases 1 and a plurality of connecting members 2.

[0039] Specifically, the plurality of bases 1 are distributed one by one at the corners of the fixed frame, and the adjacent bases 1 are connected by the connecting members 2. The plurality of bases 1 and the plurality of connecting members 2 together enclose a frame body similar to a ring. The fixed frame can adopt a split design, and the base 1 and the connecting member 2 are separately formed and then fixed together by welding, bolt connection or the like. The fixed frame can also adopt an integrated design, and an integrated fixed frame is directly obtained by sheet metal bending, machine tool processing or the like. At this time, the base 1 and the connecting member 2 are a whole structure and do not need to be welded or bolted. The base 1 comprises a bottom plate 11 and a side plate 12, the side plate 12 extends upward from the bottom plate 11, the bottom plate 11 is provided with a through hole 111 for the bolt 3, and the side plate 12 is provided with a first opening 123.

[0040] When the fixed frame carries the scale platform 5 and needs to level the scale platform 5, the operator can insert the torque output end of the torque applying tool 9 into the inside of the base 1 through the first opening 123 and cooperate with the bolt 3 in the through hole 111. After the torque applying tool 9 applies torque to the bolt 3, the bolt 3 can be loosened, and the operator can lift the base 1 upward, place the gasket 4 at the bottom of the base 1, and then adjust the height of the fixed frame to level the scale platform 5. The whole leveling process does not need to lift the scale platform 5, simplifies the leveling steps of the scale platform 5, and improves the leveling efficiency of the scale platform 5.

[0041] In actual application, the operator is more inclined to pass the torque applying tool 9 through the first opening 123 along the opening direction of the first opening 123, at this time, if the hole 111 deviates from the opening direction of the first opening 123, the operator needs to deflect the torque applying tool 9, which increases the difficulty of screwing the bolt 3 in the hole 111.

[0042] Therefore, in order to reduce the difficulty of cooperation between the torque applying tool 9 and the bolt 3 in the hole 111, the hole 111 should be arranged as much as possible along the opening direction of the first opening 123. Preferably, the position of the hole 111 on the bottom plate 11 satisfies that the vertical projection of the hole 111 is completely located in the vertical projection of the first opening 123 in the plane parallel to the side plate 12.

[0043] In an embodiment, referring to FIG. 1, in order to protect the components installed on the base 1, the side plate 12 includes a first side plate 121 and a second side plate 122, the first side plate 121 and the second side plate 122 have an included angle and are connected to each other. The first opening 123 is arranged at the connection between the first side plate 121 and the second side plate 122 and extends along the first side plate 121 and the second side plate 122 for a certain distance. Figure 3

[0044] In other embodiments, the first opening 123 can also be arranged only on the first side plate 121 or the second side plate 122.

[0045] Further, the bottom plate 11 of the base 1 and the first side plate 121 and the second side plate 122 can be integrally formed by bending process, or can be spliced by welding, bolt connection and other processes. When the base 1 is manufactured by bending process, the first side plate 121 and the second side plate 122 can be fixed together by welding after bending.

[0046] Optionally, the included angle between the first side plate 121 and the second side plate 122 is substantially 90°.

[0047] Optionally, the bottom plate 11 is substantially configured as a plate body in the shape of a right triangle, and the first side plate 121 and the second side plate 122 are correspondingly distributed on two right angle sides of the bottom plate 11.

[0048] ​Furthermore, when the first opening 123 is located at the connection between the first side plate 121 and the second side plate 122 and extends to the first side plate 121 and the second side plate 122, in order to further reduce the difficulty of the torque application tool 9 engaging with the bolt 3 in the through hole 111, the position of the through hole 111 on the base plate 11 satisfies the following: on a plane parallel to the first side plate 121, the vertical projection of the through hole 111 is completely within the vertical projection of the first opening 123; and on a plane parallel to the second side plate 122, the vertical projection of the through hole 111 is completely within the vertical projection of the first opening 123, so that the through hole 111 is simultaneously close to the first side plate 121 and the second side plate 122, so that when the torque application tool 9 passes through the first opening 123 from any direction, it can quickly engage with the bolt 3 in the through hole 111.

[0049] In one embodiment, reference is made to Figure 3 As shown, in order to increase the size of the first opening 123 and reduce the probability of interference between the side plate 12 and the torque application tool 9, the first opening 123 should extend downward as much as possible, so that the lower edge of the first opening 123 is flush with the top surface of the base plate 11, so that the first opening 123 can expose the bolt 3 on the base plate 11 as much as possible, so that the torque application tool 9 can cooperate with the bolt 3.

[0050] Furthermore, in order to ensure the structural strength of the side plate 12 and reduce the probability of deformation and bending of the side plate 12, the first opening 123 should not extend upward through the top surface of the side plate 12. That is, there should be a gap between the upper edge of the first opening 123 and the top surface of the side plate 12, so as to ensure that the side plate 12 has sufficient structural strength to protect and limit the components installed inside the base 1.

[0051] In one embodiment, reference is made to Figure 1 and Figure 2 As shown, the fixed frame is constructed as a rectangular frame structure, with four bases 1 and four connecting members 2, and the four bases 1 are distributed at the four corners of the fixed frame.

[0052] In one embodiment, reference is made to Figure 3 As shown, the connecting member 2 is connected to the top surface of the base plate 11, and the base plate 11 and the connecting member 2 can be connected together by welding, bolts or other fixing methods. The connecting member 2 can be set as an angle steel structure or a plate structure.

[0053] Reference Figure 4As shown, the conventional gasket is provided with a hole for the bolt 3 on the base 1 to pass through. Such a gasket 4 cannot be applied to the fixed frame in the above embodiment, and cannot be placed on the bottom of the base 1 without completely disassembling the bolt 3. Therefore, if the gasket 4 is not improved, it can only be simply placed on the bottom of the base 1, and the bolt 3 on the base 1 cannot limit the gasket 4. After a long weighing work, the gasket 4 and the base 1 are prone to relative movement, affecting the accuracy of the weighing result.

[0054] Therefore, in the following embodiments, the conventional gasket is mainly improved, so that the gasket can be placed on the bottom of the base 1 without completely disassembling the bolt 3, and can cooperate with the bolt 3 on the base 1.

[0055] Based on the above idea, in an embodiment, referring to Figures 1 to 3 and Figures 5 to 6 As shown, the fixed frame further comprises a plurality of gaskets 4, and the gasket 4 is provided with a relief hole 41 which penetrates one side edge of the gasket 4.

[0056] When it is necessary to install the gasket 4 on the bottom of the base 1, the operator loosens the bolt 3 on the base 1 and lifts the base 1 upward, then places the gasket 4 on the bearing surface of the bearing fixed frame, so that the relief hole 41 of the gasket 4 is aligned with the threaded portion of the bolt 3 below the base 1, and then inserts the gasket 4 into the bottom of the base 1, so that the bolt 3 is placed in the relief hole 41 to form a limiting structure with the relief hole 41, thereby reducing the probability of relative movement between the gasket 4 and the base 1.

[0057] In actual application, the number of gaskets 4 can be set according to the site requirements. A single gasket 4 can be placed on the bottom of any base 1, or a plurality of gaskets 4 stacked together can be placed on the bottom of any base 1. The number of gaskets 4 placed on the bottom of each base 1 can be equal or unequal. Even under the condition of meeting the leveling requirement, the bottom of the base 1 can also not be placed with the gasket 4.

[0058] In addition, in order to facilitate the rotation of the bolt 3, the perforation 111 is usually arranged in a relatively more outward area of the base 1 (i.e. a relatively more outward area of the side plate 12). Since the gasket 4 needs to have sufficient contact area with the base 1, the relief hole 41 extends from one side edge of the gasket 4 to the opposite side edge as much as possible, resulting in a relatively long horizontal length of the relief hole 41, which reduces the structural strength of the gasket 4, causing the gasket 4 to be easily deformed under external force, affecting the accuracy of the weighing result.

[0059] To solve the above problem, in an embodiment, referring to Figure 5As shown, the gasket 4 comprises a first segment 42 and a second segment 43, the first segment 42 extends along a first direction from the side of the first segment 42, the length L1 of the first segment 42 in a second direction is greater than the length L2 of the second segment 43 in the second direction, and the avoiding hole 41 is recessed from the side of the first segment 42 close to the second segment 43 along the first direction. The first direction can refer to Figure 5 the X-axis direction as shown, the second direction can refer to Figure 5 the Y-axis direction as shown, both the first direction and the second direction are perpendicular to the normal direction of the gasket 4, and the first direction is also perpendicular to the second direction.

[0060] According to the above structural design, it can be seen that the minimum length area of the gasket 4 in the first direction is located in the area where the first segment 42 and the second segment 43 are staggered, and after the avoiding hole 41 is arranged in this area, the length of the avoiding hole 41 in the first direction can be reduced, the influence of the avoiding hole 41 on the structural strength of the gasket 4 is reduced, and the probability of bending deformation of the gasket 4 under external force is reduced.

[0061] In addition, when the gasket 4 is placed on the bottom of the base 1, the second segment 43 is first directed towards the gap between the base 1 and the bearing surface, and then the gasket 4 is placed on the bottom of the base 1, and the avoiding hole 41 is matched with the bolt 3 on the base 1.

[0062] In an embodiment, referring to Figure 1 , Figure 2 and Figure 7 , the application also provides a weighing system, which comprises the fixed frame, the scale table 5, the plurality of connecting seats 6, the plurality of weighing sensors 7 and the plurality of connecting columns 8 in the above embodiments.

[0063] Specifically, the scale table 5 is located at the top of the fixed frame, and the plurality of corners at the edges of the scale table 5 are arranged one by one corresponding to the plurality of bases 1 of the fixed frame. The plurality of connecting seats 6 are arranged one by one on the bottom plates 11 of the plurality of bases 1, and the top of each connecting seat 6 is provided with a first connecting hole 621. The plurality of weighing sensors 7 are arranged on the bottom of the scale table 5 and correspond to the plurality of connecting seats 6 one by one, and the bottom of each weighing sensor 7 is provided with a second connecting hole 71. The plurality of connecting columns 8 are connected one by one with the plurality of connecting seats 6 and the plurality of weighing sensors 7, the bottom end of the connecting column 8 is inserted into the first connecting hole 621 of the connecting seat 6, and the top end of the connecting column 8 is inserted into the second connecting hole 71 of the weighing sensor 7.

[0064] Wherein, the positions of the connecting seat 6 and the through hole 111 should be arranged to satisfy that when the torque applying tool 9 is inserted into the first opening 123 of the base 1, the connecting seat 6 does not interfere with the torque applying tool 9, so that the torque applying tool 9 can be matched with the bolt 3 in the through hole 111 to apply torque to the bolt 3 in the through hole 111 to screw the bolt 3.

[0065] In an embodiment, referring to Figure 8 When the first opening 123 is located at the connection between the first side plate 121 and the second side plate 122 and extends to the first side plate 121 and the second side plate 122, the through hole 111 should be arranged as close to the first side plate 121 and the second side plate 122 as possible, and the connecting seat 6 should be arranged as far away from the first side plate 121 and the second side plate 122 as possible.

[0066] Specifically, the horizontal distance between the first side plate 121 and the center of the through hole 111 is L3, the horizontal distance between the first side plate 121 and the center of the connecting seat 6 is L4, the horizontal distance between the second side plate 122 and the center of the through hole 111 is L5, and the horizontal distance between the second side plate 122 and the center of the connecting seat 6 is L6. The first side plate 121, the second side plate 122, the through hole 111 and the connecting seat 6 are arranged to satisfy L3 < L4 and L5 < L6.

[0067] In an embodiment, referring to Figure 7 As shown in the figure, the connecting seat 6 includes a first seat body 61 fixed to the bottom plate 11 and a second seat body 62 threadedly connected with the first seat body 61. The second seat body 62 protrudes upward from the first seat body 61, and a first connecting hole 621 is formed in the second seat body 62.

[0068] Further, a threaded hole 611 is formed in the first seat body 61, and the second seat body 62 is threadedly connected in the threaded hole 611. When it is necessary to level the scale platform 5, the operator can rotate the corresponding second seat body 62 to adjust the height of the second seat body 62, thereby adjusting the height of the edge area of the scale platform 5 and leveling the scale platform 5.

[0069] In order to facilitate the cooperation between the torque applying tool 9 and the second seat body 62, and to apply torque to the second seat body 62 to rotate the second seat body 62, in an embodiment, referring to Figure 3 and Figure 7 As shown in the figures, the second seat body 62 is provided with a radially protruding connecting part 622. In a plane perpendicular to the axial direction of the second seat body 62, the vertical projection of the connecting part 622 is a regular polygon.

[0070] Optionally, in a plane perpendicular to the axial direction of the second seat body 62, the vertical projection of the connecting part 622 is approximately a regular hexagon.

[0071] Further, when the torque applying tool 9 cooperates with the connecting part 622, in order to avoid interference between the side plate 12 and the torque applying tool 9, the top surface of the connecting part 622 should always be lower than the top edge of the first opening 123, and the bottom surface of the connecting part 622 should always be higher than the bottom edge of the first opening 123.

[0072] In another embodiment, referring to Figure 9As shown, the connecting seat 6 can also adopt an integrated design. The connecting seat 6 is an integrally formed structure and is fixed on the base plate 11 of the base 1. The weighing platform 5 is leveled by placing a pad 4 at the bottom of the base 1.

[0073] In one embodiment, to prevent the base 1 from protruding horizontally from the weighing platform 5 and causing a collision between the base 1 and other objects, the base 1 and the weighing platform 5 are configured to satisfy the following: the vertical projection of any one of the base 1s onto the top surface of the weighing platform 5 is completely located on the top surface of the weighing platform 5.

[0074] Of course, in other embodiments, when there is no need to consider that the base 1 will collide with other objects, the position of the base 1 can be adjusted or the structure of the base 1 can be improved so that the base 1 protrudes relatively from the weighing platform 5 in the horizontal direction.

[0075] In one embodiment, reference is made to Figure 2 As shown, the side of the weighing platform 5 is wrapped by the side plate 12 on the base 1. In order to avoid the area of ​​the weighing platform 5 near the first opening 123 from interfering with the torque application tool 9, a second opening 51 is provided on the part of the weighing platform 5 facing the side plate 12. The opening direction of the second opening 51 is towards the first opening 123, so as to avoid the torque application tool 9.

[0076] It should be noted that the torque application tool 9 in the above embodiments includes, but is not limited to, manual wrenches, electric wrenches, pneumatic wrenches, and hydraulic wrenches. In actual applications, the torque application tool 9 that is compatible with the bolt 3 and its installation status, as well as the shape of the connecting part 622 of the connecting seat 6, should be selected. The torque application tools 9 that are compatible with the bolt 3 and the connecting seat 6 can be the same or different.
