Description

Technical Field

[0001] This application relates to belt weighing technology, and more particularly to a belt weighing device. Background Technology

[0002] In the process of ferroalloy production, belt weighing machines are generally used to weigh and batch various raw materials according to a given ratio.

[0003] Currently, a belt weighing device used in ferroalloy production batching includes a frame and a belt conveyor. Four cantilever beam load cells are installed at the upper end of the frame, and the four corners of the lower end of the belt conveyor are connected to the four cantilever beam load cells respectively. The four cantilever beam load cells support the belt conveyor and weigh it.

[0004] However, in actual use, when the cantilever beam load cell malfunctions and needs to be disassembled and replaced, it is not convenient to support the belt conveyor, making the disassembly and replacement of the entire cantilever beam load cell operation quite cumbersome. Utility Model Content

[0005] This application provides a belt weighing device to solve the problem that existing belt weighing devices are inconvenient to support the belt conveyor when disassembling and replacing the cantilever beam load cell, and the disassembly and replacement operation of the entire cantilever beam load cell is relatively cumbersome.

[0006] This application provides a belt weighing device, including a frame and a belt conveyor. Two symmetrically distributed horizontal columns are installed at the lower end of the belt conveyor and are distributed along its width direction. Cantilever beam load cells installed at the bottom of both ends of the horizontal columns are connected to the bottom of the frame. The lower end of the horizontal column is fixed with two symmetrically distributed support blocks; A support column is provided below the horizontal column. The support column is connected to a screw drive mechanism that can drive it to move linearly along the horizontal column. The support column can move to the lower end of the support block and contact the lower end of the support block.

[0007] Optionally, the lower end of the support block is provided with inclined structure I, and the upper end of the supported column is provided with two symmetrically distributed inclined structures II. The inclination of the inclined structure I is the same as the inclination of the inclined structure II, which can be moved to its lower end.

[0008] Optionally, the frame includes two hollow crossbeams parallel to the cross columns, two symmetrically distributed longitudinal beams connecting the two crossbeams, and two symmetrically distributed support frames connecting the two crossbeams. The lead screw drive mechanism includes a lead screw, which is disposed inside the crossbeam and rotatably connected to the crossbeam; The upper end of the crossbeam is provided with a sliding groove, the support column passes through the sliding groove and is slidably connected to the sliding groove, and the lead screw passes through the support column and is threadedly connected to the support column.

[0009] Optionally, when the support column contacts the end of the slide groove, the upper end of the support column contacts the lower end of the support block located above it.

[0010] Optionally, both ends of the lead screw extend to the side of the crossbeam and are fixed with handwheels.

[0011] Optionally, the cantilever beam load cell is fixedly connected to the crossbeam by bolts, and the cantilever beam load cell is connected to the end of the cross column by bolts. The cantilever beam load cell and the end of the cross column are both located on the side of the belt conveyor.

[0012] The belt weighing device provided in this application consists of two symmetrically distributed horizontal columns installed at the lower end of the belt conveyor, extending along its width. Cantilever beam load cells, mounted on the upper part of the frame, are connected to the bottom of each horizontal column. Two symmetrically distributed support blocks are fixed to the lower end of the horizontal column. A support column is located below the horizontal column, connected to a screw drive mechanism that moves it linearly along the horizontal column. The support column can move to the lower end of the support block and contact it. This allows for easy replacement of the cantilever beam load cells. First, the screw drive mechanism is operated to move the support column. Once the support column moves close to the lower end of the support block containing the cantilever beam load cell to be replaced and contacts the lower end of the support block, the cantilever beam load cell can be replaced. Furthermore, only the screw drive mechanism needs to be operated to support the belt conveyor, facilitating quick and convenient support work. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0017] like Figures 1-3 As shown: An embodiment of this application provides a belt weighing device, including a frame 1 and a belt conveyor 2. Two symmetrically distributed horizontal columns 3 are welded and fixed to the lower end of the belt conveyor 2 along its width direction. The bottom of both ends of the horizontal columns 3 are connected to cantilever beam weighing sensors 4 installed on the upper end of the frame 1.

[0018] In this embodiment, both the belt conveyor 2 and the cantilever beam load cell 4 are existing technologies and will not be described in detail.

[0019] Two symmetrically distributed support blocks 5 are welded and fixed to the lower end of the horizontal column 3, that is, a support block 5 is set on the side of each cantilever beam load cell 4.

[0020] A support column 6 is provided below the horizontal column 3. The support column 6 is connected to a screw drive mechanism 7 that can drive it to move linearly along the horizontal column 3. The screw drive mechanism 7 is installed on the frame 1. The support column 6 can move to the lower end of the support block 5 and contact the lower end of the support block 5. That is, the support column 6 can move to the lower end of any support block 5 at the lower end of the horizontal column 3.

[0021] During use, when the belt conveyor 2 is weighing, the support column 6 is located between the two support blocks 5, and there is a gap between the support column 6 and the cross column 3, so that the support column 6 will not affect the weighing operation of the belt conveyor 2.

[0022] When it is necessary to replace the cantilever beam load cell 4, first operate the screw drive mechanism 7 located on the same side as the cantilever beam load cell 4. The screw drive mechanism 7 drives the support column 6 to move, moving the support column 6 to the lower end of the support block 5 close to the cantilever beam load cell 4. When the support column 6 moves to the lower end of the support block 5 and contacts the lower end of the support block 5 with the support cross column 3, stop moving the support column 6. At this time, the support column 6 and the support block 5 support the cross column 3, which in turn supports the belt conveyor 2. Then, remove the cantilever beam load cell 4 to be replaced and install the new cantilever beam load cell 4. When the new cantilever beam load cell 4 is installed, move the support column 6 between the two support blocks 5. At this time, the belt conveyor 2 can continue to perform weighing operations.

[0023] The belt weighing device provided in this embodiment has two symmetrically distributed horizontal columns 3 installed at the lower end of the belt conveyor 2 along its width direction. The bottom of both ends of the horizontal columns 3 are connected to cantilever beam load cells 4 installed on the upper end of the frame 1. Two symmetrically distributed support blocks 5 are fixed at the lower end of the horizontal columns 3. A support column 6 is provided below the horizontal column 3. The support column 6 is connected to a screw drive mechanism 7 that can drive it to move linearly along the horizontal column 3. The support column 6 can move to the lower end of the support block 5 and contact the lower end of the support block 5. This allows the belt conveyor 2 to be supported by simply operating the screw drive mechanism 7 when disassembling or replacing the cantilever beam load cells 4. This makes it easier for workers to support the belt conveyor 2 and allows for quick and convenient support of the belt conveyor 2.

[0024] In some embodiments of this application, the lower end of the support block 5 is provided with an inclined structure I 501, and the upper end of the supported column 6 is provided with two symmetrically distributed inclined structures II 601. The inclination of inclined structure I 501 is the same as that of inclined structure II 601, which can be moved to its lower end.

[0025] like Figure 2 As shown, in this embodiment, the two support blocks 5 are symmetrically distributed from left to right, that is, the inclined surface structure I 501 of the two support blocks 5 is symmetrically distributed from left to right, and the two inclined surface structure II 601 are also symmetrically distributed from left to right. The inclined surface structure I 501 on the left side can overlap with the inclined surface structure II 601 on the left side, and the inclined surface structure I 501 on the right side can overlap with the inclined surface structure II 601 on the right side.

[0026] like Figure 2As shown, in use, after the support column 6 moves to the left, when the inclined structure II 601 on the left coincides with the inclined structure I 501 on the left, the upper end of the support column 6 contacts the lower end of the support block 5 above it, and the support column 6 and the support block 5 support the left part of the horizontal column 3; after the support column 6 moves to the right, when the inclined structure II 601 on the right coincides with the inclined structure I 501 on the right, the upper end of the support column 6 contacts the lower end of the support block 5 above it, and the support column 6 and the support block 5 support the right part of the horizontal column 3.

[0027] In this embodiment, by setting inclined structure I 501 and inclined structure II 601, it is convenient for the upper end of the support column 6 to contact the lower end of the support block 5 when the support column 6 moves.

[0028] In some embodiments of this application, the frame 1 includes two hollow beams 101 parallel to the crossbeams 3, two symmetrically distributed longitudinal beams 102 welded and fixed between the two beams 101, and two symmetrically distributed support frames 103 welded and fixed between the two beams 101.

[0029] The lead screw drive mechanism 7 includes a lead screw 701, which is disposed inside the crossbeam 101 and rotatably connected to the crossbeam 101. Specifically, both ends of the crossbeam 101 are rotatably connected to the lead screw 701 via bearings.

[0030] The upper end of the crossbeam 101 is provided with a sliding groove 8, the support column 6 passes through the sliding groove 8 and is slidably connected to the sliding groove 8, and the lead screw 701 passes through the support column 6 and is threadedly connected to the support column 6.

[0031] In use, the lead screw 701 is rotated. After the lead screw 701 rotates, under the limiting action of the slide groove 8, the lead screw 701 drives the support column 6 to move linearly along the slide groove 8. That is, the operator only needs to rotate the lead screw 701 on the side of the frame 1 to move the support column 6 to the lower end of the corresponding support block 5, so that the support work of the belt conveyor 2 can be realized.

[0032] In some embodiments of this application, when the support column 6 contacts the end of the slide 8, the upper end of the support column 6 contacts the lower end of the support block 5 located above it. After the upper end of the support column 6 contacts the lower end of the support block 5 located above it, the end of the slide 8 limits the support column 6, and the support column 6 cannot continue to move. This makes it easier for workers to confirm whether the upper end of the support column 6 contacts the lower end of the support block 5 located above it.

[0033] In some embodiments of this application, both ends of the lead screw 701 extend to the side of the crossbeam 101 and are fixed with handwheels 702, so that workers can manually rotate the handwheels 702 to drive the lead screw 701 to rotate from both sides of the frame 1. Thus, when replacing the cantilever beam load cell 4, the workers only need to stand at the position of the cantilever beam load cell 4 to be replaced to rotate the lead screw 701.

[0034] In some embodiments of this application, the cantilever beam load cell 4 is fixedly connected to the crossbeam 101 by bolts, and the cantilever beam load cell 4 is connected to the end of the cross column 3 by bolts. Both the end of the cantilever beam load cell 4 and the end of the cross column 3 are located on the side of the belt conveyor 2, which facilitates the operator to use a wrench to install and remove the bolts.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
