[0029] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.
[0030] Embodiment 1, as Figures 1 to 3 As shown, this embodiment provides a load-bearing weighing device, including: an upper top plate assembly 1 and a lower bottom plate 2, wherein one side of the upper top plate assembly 1 has a matching hole 11, one side of the lower bottom plate 2 has a mounting hole, and the lower bottom plate 2 has a mounting seat 21, and the mounting seat 21 is fixedly connected to the lower bottom plate 2 by plug welding with the mounting hole. The load-bearing weighing device also has a pull rod 3, the two ends of which are respectively connected to the matching hole 11 and the mounting seat 21, and the pull rod 3 is arranged on the outer side of the upper top plate assembly 1. It should be noted that in the prior art, the mounting seat 21 and the lower bottom plate 2 are directly welded, while in this embodiment, by first opening a mounting hole on the lower bottom plate 2, and then plug welding the mounting seat 21 with the mounting hole, the connection strength between the mounting seat 21 and the lower bottom plate 2 can be enhanced.
[0031] One end of the tie rod 3 is hingedly fixed to the upper plate assembly 1 through the pin shaft 31 and the matching hole 11, and the other end of the tie rod 3 is hingedly fixed to the lower base plate 2 through the pin shaft 31 and the support seat, because the upper plate assembly 1 and the lower base plate 2 are hingedly connected through the tie rod 3. By setting the tie rod 3, when the upper plate assembly 1 is subjected to horizontal force, it will be first transmitted to the tie rod 3, and then transmitted to the mounting seat 21 and the lower base plate 2 through the tie rod 3, thereby ensuring that the load-bearing weighing device only bears vertical force, avoiding the relative displacement of the load-bearing weighing device caused by the influence of horizontal external force during the weighing process, so that the weighing error is small and the precision is high during weighing.
[0032] The upper top plate assembly 1 includes a weighing table 12, a floating plate 13 and a plurality of support columns 14. The two ends of the support columns 14 are fixedly connected to the weighing table 12 and the floating plate 13 respectively. The lowest point of the support column 14 is flush with the bottom surface of the floating plate 13, and the floating plate 13 is arranged floatingly above the lower bottom plate 2. In addition, it should be noted that in the prior art, the overall load-bearing weighing device needs to install the pull rod first, and then the upper top plate assembly 1 is buckled on the lower bottom plate 2 as a whole. This installation method cannot clamp the pull rod 3 when the load-bearing weighing device is installed and used. In this embodiment, one side of the mounting seat 21 is arranged to protrude from the side wall of the lower bottom plate 2, so that the distance between the mounting seat 21 and the support column 14 is increased, thereby facilitating the clamping of the retaining ring and the pull rod 3 on the pin shaft 31.
[0033] The load-bearing weighing device also includes a weighing mechanism 4, which includes a weighing sensor 41, an upper pressure head 42 and a lower pressure head 43. The upper pressure head 42 and the lower pressure head 43 are respectively plugged into the two ends of the weighing sensor 41, the upper pressure head 42 is sleeved with the hole in the middle of the weighing table 12, and the lower pressure head 43 is sleeved with the hole in the middle of the lower bottom plate 2. The weighing mechanism 4 penetrates through the hole in the middle of the floating plate 13, and the weighing mechanism 4 is not in contact with or fixed to the suspension plate. The weighing mechanism 4 is located in the middle of the load-bearing weighing device. Each support column 14 forms a double H-cage structure with the weighing table 12 and the floating plate 13, so as to provide good rigidity and good protection for the weighing sensor 41.
[0034] The load-bearing weighing device further includes two limit connectors 5, which are mirror-imaged on both sides of the upper top plate assembly 1. The left and right ends of the limit connector 5 are respectively fitted with the two adjacent support columns 14 to prevent the upper top plate assembly 1 from shifting left and right, and the two limit connectors 5 are respectively abutted with the upper top plate assembly 1 from both sides to prevent the upper top plate assembly 1 from shifting forward and backward, thereby achieving the effect of the limit connector 5 on the horizontal position limitation of the upper top plate assembly 1.
[0035] The structure of the position-limiting connector 5 is described in detail below. The position-limiting connector 5 includes a pressure plate 51, a cushion block 52 and a plurality of connecting bolts 53 which are separately arranged. The connecting bolts 53 pass through the pressure plate 51 and the cushion block 52 in sequence and are connected to the lower bottom plate 2. One end of the pressure plate 51 is in an overlapping state with the floating plate 13 at the corresponding position. The pressure plate 51 is placed above the floating plate 13, and the cushion block 52 is placed below the floating plate 13, which limits the floating distance of the floating plate 13.
[0036] The outer sides of the connecting bolts 53 are respectively sleeved with limiting sleeves 54 . The length of the connecting bolts 53 is longer than that of the limiting sleeves 54 . The limiting sleeves 54 can protect the connecting bolts 53 , thereby extending the service life of the connecting bolts 53 .
[0037] The position-limiting connector 5 further includes a lower pad 55 and an upper pad 56 which are separately arranged. The lower pad 55 and the upper pad 56 are respectively arranged on the upper and lower sides of the cushion block 52 .
[0038] A guiding slope 141 is provided on the outer side of the support column 14, and the lower pad 55 is located below the pad 52, and the width of the lower pad 55 is greater than the spacing distance between the two adjacent support columns 14, and the lower pad 55 is placed between the ends of the two adjacent support columns 14 and the lower base plate 2. In addition, the upper pad 56 is arranged between the pressure plate 51 and the floating plate 13, and finally tightened and fixed by the connecting bolts 53, so that the overall limiting connector 5 clamps the floating plate 13 and is fixed on the lower base plate 2, thereby forming a protective cover with a supporting function that cannot be deflected left and right and cannot float up and down, so as to avoid damage to the equipment due to pressure during transportation. At the same time, it is more convenient to replace the sensor in this state without requiring too many tools for removal, thereby improving efficiency.
[0039] The hole between the lower pad 55 and the upper pad 56 is in the shape of a long strip. There is no need to remove the limiting connector 5 for later adjustment. It is only necessary to loosen the connecting bolt 53 and pull the upper pad 56 and the lower pad 55 outward along the direction of the hole. At this time, the upper top plate assembly 1 is in a suspended state and can start weighing.
[0040] Preferably, one side of the lower pad 55 and the upper pad 56 can be pulled outwards and is provided with a step, which protrudes from the plane of the limiting connector 5 during installation, making it more convenient to pull out later.
[0041] Compared with the prior art, the embodiment of the utility model has the following beneficial effects: through the limiting connector 5, no external force is applied during the entire assembly, transportation and on-site installation process, and the weighing sensor 41 is better protected in each process to avoid damage to the sensor due to impact force.
[0042] The overall limiting connector 5 clamps the floating plate 13 and is fixed on the lower base plate 2, thereby forming a protective cover that cannot deviate left or right and cannot float up and down and has a supporting function, thereby preventing the equipment from being damaged by pressure during transportation. At the same time, it is more convenient to replace the sensor without the need for other tools for removal, thereby improving efficiency.
[0043] It is worth mentioning that the technical features such as other components of the load-bearing weighing device involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected according to the conventional methods in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated.
[0044] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
