Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, in particular to an electrode paste bag hoisting tool. Background Art

[0002] Electrode paste, also known as self-baking electrode, is usually a mixture of various carbon-based materials and binders. It is mainly used as a conductive material in electric furnaces and is smelted by generating an arc through electric current. It is a key raw material for the production of metal or non-metallic products such as calcium carbide, ferroalloys, and yellow phosphorus. During its transportation, it usually needs to be loaded into electrode paste bags, and then lifted by slings and transported to the designated location. The handles of the electrode paste bags are usually distributed at the four corners.

[0003] According to the Chinese patent announcement number: CN218950814U, an electrode paste bag lifting tool includes a first hanger, two second hangers and a hanging assembly. Each second hanger is fixedly connected to the first hanger. The hanging assembly includes four connecting plates and connecting parts. Each connecting plate is provided with a groove. The two ends of the first hanger are respectively located in two grooves, and the free end of each second hanger is respectively located in the other two grooves. A hook is fixed to the bottom of each connecting plate, and a lifting ear is connected to the connection between the first cross bar and the second cross bar.

[0004] In the above solution, the hooks are fixed by connecting plates. However, the above solution still has the following shortcomings: although the pre-installed slings on the electrode paste bags are hung by four hooks, thereby lifting four bags of electrode paste at the same time, it is not considered that during the lifting process, because the electrode paste in the bags has a large density and therefore has a large inertia, it is very likely that during the lifting process, the electrode paste in the bags will fall out of the bags due to shaking, which greatly affects the efficiency of transportation and poses certain safety hazards. Utility Model Content

[0005] The purpose of the utility model is to provide an electrode paste bag lifting tool to solve the problem that the electrode paste in the bag falls out of the bag due to shaking during the lifting process.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical solutions: an electrode paste bag lifting tool, comprising four hanging columns, the four hanging columns are arranged at intervals, and eight connecting blocks are connected to the four sides of the hanging columns, two of the connecting blocks are a group, and a hanging rod is rotatably connected between the two connecting blocks. A first rotating hole is opened inside the two connecting blocks, and a second rotating hole is opened on one side of the hanging rod. A rotating shaft is connected to the inside of the second rotating hole, and the two ends of the rotating shaft are rotatably inserted into the two first rotating holes. Four connecting columns are connected to the four sides of the hanging column, and a fixed block is connected to the hanging rod. The end of the connecting column away from the hanging column is connected to a tension spring, and the other end of the tension spring is connected to the fixed block.

[0007] Preferably, one end of the connecting column is connected to a limiting block, wherein the length of the protruding portion of the connecting column at one end away from the suspension column is adapted to the width of the pull ring of the tension spring, and the diameter of the limiting block is equal to the diameter of the annular portion of the outer wall of the connecting column.

[0008] Preferably, one end of the suspension rod away from the suspension column is connected with a hook.

[0009] Preferably, the top surfaces of the four suspension columns are connected to connecting arms, and the sides of the four connecting arms close to each other are connected to connecting rods.

[0010] Preferably, the top surface of the connecting rod is connected with a hanging ring, and the hanging ring is a semicircular ring structure.

[0011] Compared with the existing technology, the electrode paste bag lifting tool using the above technical solution has the following beneficial effects:

[0012] 1. During use, the staff first connects the lifting ring to the crane, and then drives the crane to a suitable position. At this time, the four handles of the four bags of electrode paste can be hung on the four hanging rods in turn, and the crane is operated to lift the entire device. At this time, as the electrode paste bags gradually rise, the four hanging rods will be driven to rotate downward due to the action of gravity. Because the end of the hanging rod close to the hanging column is rotated through the rotating shaft and the two connecting blocks, only the end away from the hanging column will drop. At this time, as the end of the four hanging rods away from the hanging column drops, the outer area surrounded by the four hanging rods will become smaller, thereby naturally tightening the upper opening of the electrode paste bag. After that, it can be transported, avoiding the situation of electrode paste falling during transportation, thereby improving transportation efficiency and safety;

[0013] 2. During use, the connecting column is connected to the boom by a tension spring, and the boom and the tension spring are initially parallel. During transportation, the boom descends, stretching the tension spring. After transportation, the gravity exerted by the electrode paste bag disappears, and the tension spring pulls the boom to reset it to facilitate the next transportation.

[0014] 3. During use, the hook connected to the end of the boom away from the hanging column further prevents the electrode paste bags from falling during transportation. The four connecting arms are connected to the four hanging columns, so that four electrode paste bags can be transported each time, which improves the transportation efficiency.

[0020] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 and Figure 3 As shown, an electrode paste bag lifting tool includes four hanging columns 1, which are arranged at intervals. Eight connecting blocks 2 are connected to the four sides of the hanging columns 1, two connecting blocks 2 form a group, and a hanging rod 3 is rotatably connected between the two connecting blocks 2. A first rotating hole 4 is opened inside the two connecting blocks 2, and a second rotating hole 5 is opened on one side of the hanging rod 3. The interior of the second rotating hole 5 is connected to a rotating shaft 6, and the two ends of the rotating shaft 6 are rotatably inserted into the two first rotating holes 4.

[0022] During use, the staff first connects the lifting ring 14 to the crane, and then drives the crane to a suitable position. At this time, the four handles of the four bags of electrode paste can be hung on the four hanging rods 3 in turn, and the crane is operated to lift the entire device. At this time, as the electrode paste bags gradually rise, the four hanging rods 3 will be driven to rotate downward due to the action of gravity. The hanging rod 3 is rotated with the two connecting blocks 2 through the rotating shaft 6 at one end close to the hanging column 1, and only the end away from the hanging column 1 will drop. At this time, due to the descent of the ends of the four hanging rods 3 away from the hanging column 1, the outer area surrounded by the four hanging rods 3 will become smaller, thereby achieving the effect of naturally tightening the upper opening of the electrode paste bag. After that, it can be transported, avoiding the situation where the electrode paste falls during transportation, thereby improving the efficiency and safety of transportation.

[0023] like Figure 3 and Figure 4 As shown, four connecting columns 7 are connected to the four sides of the suspension column 1, a fixed block 8 is connected to the suspension rod 3, the end of the connecting column 7 away from the suspension column 1 is connected to a tension spring 9, the other end of the tension spring 9 is connected to the fixed block 8, and one end of the connecting column 7 is connected to a limiting block 10, wherein the length of the protruding part of the end of the connecting column 7 away from the suspension column 1 is adapted to the width of the pull ring of the tension spring 9, and the diameter of the limiting block 10 is equal to the diameter of the annular part of the outer wall of the connecting column 7.

[0024] During use, the connecting column 7 is connected to the suspension rod 3 by the tension spring 9, and the initial state is that the suspension rod 3 and the tension spring 9 are parallel. During transportation, the suspension rod 3 descends, which stretches the tension spring 9. After the transportation is completed, the gravity exerted by the electrode paste bag disappears, and the tension spring 9 pulls the suspension rod 3 to reset the suspension rod 3 to facilitate the next transportation needs.

[0025] Such as 1 and Figure 2 As shown, the end of the suspension rod 3 away from the suspension column 1 is connected to a hook 11, the top surfaces of the four suspension columns 1 are connected to connecting arms 12, the side of the four connecting arms 12 close to each other is connected to a connecting rod 13, and the top surface of the connecting rod 13 is connected to a lifting ring 14, which is a semicircular ring structure.

[0026] During use, the hook 11 connected to the end of the boom 3 away from the suspension column 1 further prevents the electrode paste bags from falling during transportation. It is connected to the four suspension columns 1 through four connecting arms 12, so that four electrode paste bags can be transported each time, thereby improving the transportation efficiency.

[0027] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
