Fig. 6 is a schematic structural view of a screw assembly in the weighing protection device for a large-tonnage storage hopper of the present utility model.
As shown in fig. 3, the present utility model discloses a weighing protecting apparatus for a large tonnage storage hopper, which includes a top plate assembly 100, a bottom plate assembly 200, and a long screw assembly 300. The top plate assembly 100 is preferably a frame structure, and is mounted on the bottom plate assembly 200, and the top plate assembly 100 and the bottom plate assembly 200 are in clearance fit. The long screw assembly 300 fixedly connects the top plate assembly 100 and the bottom plate assembly 200 for preventing the top plate assembly 100 and the bottom plate assembly 200 from being separated from each other.
As shown in fig. 4, the top plate assembly 100 includes a top plate 110, two side support plates 120, a middle plate 130, and a first lug 140. The support plate 120 is fixedly connected between the top plate 110 and the middle plate 130 to form a frame structure, and the first lugs 140 are mounted on the middle plate 130.
Preferably, the middle plate 130 is provided with a pin boss coupling hole 131, and the middle plate 130 is coupled with the base plate assembly 200 through the pin boss coupling hole 131.
Further, the top plate assembly 100 further includes an integral reinforcing rib 150, and the integral reinforcing rib 150 is installed between the top plate 110, the support plate 120 and the middle plate 130 at the rear side of the top plate assembly 100.
Still further, the top plate assembly 100 further includes opening ribs 160, and the opening ribs 160 are installed between the side support plates 120 and the top and middle plates 110 and 130, respectively. The outward opening reinforcing rib 160 is designed to be an opening for welding operation convenience, and simultaneously enhances the visual effect, and can check whether the bin is subjected to the action of horizontal limit or overturning at any time.
As shown in fig. 5, the base plate assembly 200 includes a base plate 210, a plurality of second lugs 220 and a pin holder 230, wherein the second lugs 220 are respectively mounted at two side ends of the base plate 210, the pin holder 230 is mounted on the base plate 210, the upper end of the pin holder 230 is fixed with an anti-overturning plate 240, and the pin holder 230 is inserted into the pin holder connecting hole 131. Here, the pin boss connection hole 131 is preferably a pin boss waist hole.
The middle plate 130 is provided with a waist-shaped hole of a pin seat, which is designed to be used for providing horizontal limit for a bin and is designed to enable the protection device to be adjusted back and forth in the radial direction of the bin so as to facilitate the assembly of the protection device. When the sensor of the weighing module is accidentally broken, the bin falls, and after the top plate assembly 100 is contacted with the bottom plate assembly 200, the strength of the top plate assembly can support the weight of the bin.
The clearance between the pin boss 230 and the pin boss attaching hole 131 is preferably 8mm when the bin is in a normal state.
In addition, a rib 250 is installed between the second lugs 220 and the base plate 210.
As described above, the floor assembly 200 is formed by welding a floor 210, two second lugs 220 and ribs 250 thereof, and a pin boss 230, and the anti-toppling plate 240 may be fastened to the pin boss 230 by fastening bolts 260. When the bin is in a normal state, a gap exists between the pin boss 230 and the pin boss waist-shaped hole (namely the pin boss connecting hole 131) of the top plate assembly 100, so that the normal metering state of the weighing module is not affected.
When the bin is subjected to a large external force such as an earthquake to horizontally displace, the pin bosses 230 of the bottom plate assembly 200 can provide horizontal limiting for the bin. Similarly, when the bin is in a normal state, a gap exists between the anti-overturning plate 240 and the middle plate 130 of the top plate assembly 100, the normal metering state of the weighing module is not affected, and when the bin is subjected to larger external force to generate overturning tendency, the anti-overturning plate 240 of the bottom plate assembly 200 can prevent the bin from overturning.
As shown in fig. 6, the long screw assembly 300 includes a long screw 310 and a plurality of fasteners 320, wherein the long screw 310 sequentially passes through the first support lug 140 and the second support lug 220, and the long screw 310 is fixed with the first support lug 140 and the second support lug 220 into a whole by the fasteners 320.
As described above, the long screw assembly 300 consists of one relatively elongated long screw 310, multiple pairs (e.g., 6 pairs) of double nuts (i.e., fasteners 320) and shims. Here, the fastener 320 may preferably include a tightening nut 321, a standard nut 322, and a washer 323.
In operation, the long screw 310 is passed through lugs of the top plate assembly 100 and the bottom plate assembly 200, and the long screw is firmly connected with the top plate assembly by double nuts. The large-tonnage bin has large wind load due to large occupied area and high height.
When the feed bin receives wind load, long screw rod is in the both sides of roof journal stirrup, and one side is drawn one side and is pressed, because the screw rod is long and thin relatively, can bear great wind load simultaneously, through elastic deformation, the feed bin can take place less horizontal displacement, reduces the influence of wind load symmetry weight module measurement performance. Meanwhile, when the wind load is not applied, the self-return of the storage bin can be realized.
Fig. 7 is a schematic diagram of the arrangement of the weighing protection device in the silo system of the utility model.
As shown in fig. 7, the present utility model also provides a bin system comprising the weighing protection devices 400 for large tonnage bins as described above, the weighing protection devices 400 being evenly distributed at multiple points along the support ring 10 of the bin system.
According to the above structural description, the weighing protection device for large tonnage storage bins of the present utility model is mainly implemented by a three-part structure, in which the top plate assembly 100 is welded with the storage bin support ring 10.
When the weighing module is in a normal metering state, a distance of 8mm exists between the top plate assembly 100 and the bottom plate assembly 200, and normal metering performance of the weighing module is not affected.
When the sensor of the weighing module is accidentally broken, the bin falls, and after the top plate assembly 100 contacts the bottom plate assembly 200, the strength of the top plate assembly 100 can support the weight of the bin.
The bottom plate assembly 200 limits the horizontal displacement of the top plate assembly 100 by the pin bosses 230, and the strength can resist the large horizontal force caused by earthquake and the like, so that the horizontal limit protection function of the whole storage bin is achieved, and meanwhile, the anti-overturning protection of the storage bin is provided through the anti-overturning plate 240.
The long screw 310 passes through lugs of the top plate assembly 100 and the bottom plate assembly 200, is fastened by nuts (i.e., fasteners 320), and is connected with the top plate assembly to play a role in preventing wind load. As shown in fig. 7, the weighing protection devices 400 are uniformly arranged along the storage bin at multiple points as the weighing modules 20.
The weighing protection device for the large-tonnage storage bin integrates the protection functions required by the storage bin weighing, reduces the cost and is more convenient to install and maintain. The weighing protection device provides functions of horizontal limit, anti-overturning protection, vertical support protection, wind load prevention and the like for weighing of the large-tonnage storage bin.
