Description

Technical Field

[0001] This utility model relates to the field of electrolytic aluminum production technology, and more specifically, to a carbon block lifting tool and lifting device. Background Technology

[0002] Anode carbon blocks are a major consumable material in electrolytic aluminum production, serving as the anode conductor in the electrolytic cell. Because anode carbon blocks are typically large, they often require hoisting and unloading after being transported to the plant. In related technologies, steel wire ropes are often used to secure the carbon blocks before hoisting, which is time-consuming and labor-intensive, thus affecting hoisting efficiency. Utility Model Content

[0003] The problem this invention addresses is: how to improve the hoisting efficiency of anode carbon blocks.

[0004] To solve the above problems, this utility model provides a charcoal block lifting tool and lifting device.

[0005] In a first aspect, this utility model provides a charcoal block lifting device, including a lifting base, two clamping arms, and a tensioning assembly; the hinged ends of the two clamping arms are respectively hinged to the lifting base, and the portion of each clamping arm near its free end is bent toward the other clamping arm; the two clamping arms are used to swing relative to the lifting base to open or close to each other; the tensioning assembly is disposed on the lifting base and detachably connected to the two clamping arms respectively; the tensioning assembly is used to connect with the two clamping arms to limit the two clamping arms to an open state; when the tensioning assembly is separated from the two clamping arms, the two clamping arms swing and close under their own weight to clamp the charcoal block.

[0006] Optionally, the upper surface of the charcoal block is provided with a plurality of charcoal bowls; when the two clamping arms are restricted to the open state, the distance between the free ends of the two clamping arms matches the distance between the two charcoal bowls, so that the free ends of the two clamping arms can be inserted into the two charcoal bowls.

[0007] Optionally, the free end of the clamping arm is provided with a clamping plate, which is used to make close contact with the inner wall of the charcoal bowl when the two clamping arms are in the state of clamping the charcoal block.

[0008] Optionally, the outline of a portion of the edge of the clamping plate is adapted to the beveled outline of the charcoal bowl, and when the two clamping plates are clamping the charcoal block, a portion of the edge of the clamping plate is in contact with and abuts against the inner wall of the corresponding charcoal bowl.

[0009] Optionally, some edges of the clamping plate are serrated.

[0010] Optionally, the clamping arm is provided with a pull ring; the tensioning assembly has two connecting ends, each of which is provided with a hook, and the hooks on the two connecting ends are used to hook and engage with the pull rings on the two clamping arms.

[0011] Optionally, the hanging bracket is provided with a mounting hole; the tensioning assembly includes a pull rope and a limiting member, the pull rope passes through the mounting hole, the two ends of the pull rope correspondingly form two connecting ends, the two limiting members are spaced apart on the pull rope along the extension direction of the pull rope, and respectively abut against the two ends of the hanging bracket along the axial direction of the mounting hole.

[0012] Secondly, this utility model provides a hoisting device, including the charcoal block hoisting tool as described above.

[0013] Optionally, it also includes a lifting beam for connecting lifting equipment; two charcoal block lifting devices are provided, and the two charcoal block lifting devices are connected to the lifting beam at intervals, and the distance between the two charcoal block lifting devices is adapted to the distance between the charcoal bowls on two adjacent charcoal blocks.

[0014] Optionally, the two carbon block lifting devices are respectively connected to both ends of the lifting beam; the lifting beam is provided with a first lifting ring and two second lifting rings for connecting the lifting equipment, the first lifting ring is located in the middle of the lifting beam, and the two second lifting rings are respectively located at both ends of the lifting beam.

[0015] The beneficial effects of this utility model's charcoal block lifting device are as follows: By hinged to the hinged ends of the two clamping arms respectively, and simultaneously placing the tensioning assembly on the lifting base and detachably connecting it to the two clamping arms, the tensioning assembly can switch the state of the two clamping arms accordingly by changing its connection state with them. Thus, when lifting charcoal blocks, the tensioning assembly can be connected to the two clamping arms first, allowing the two clamping arms to be inserted into the two charcoal bowls in an open state. After the clamping arms are inside the charcoal bowls, the connection between the tensioning assembly and the two clamping arms can be released, and the lifting device can be raised. As the lifting device is raised, the two clamping arms can swing under their own weight. The lifting arm retracts to clamp the charcoal block, which is then lifted off the ground along with the lifting device. Once the charcoal block is in position, the lifting device can be lowered a certain distance relative to the charcoal block to release the clamping force, thus releasing the charcoal block and completing the lifting operation. Throughout the lifting process, clamping and releasing the charcoal block essentially only requires raising and lowering the lifting device. Compared to the traditional method of attaching and detaching a steel wire rope from the charcoal block, this solution simplifies the operation and improves lifting efficiency. Furthermore, because the portion of each clamping arm near its free end bends towards the other clamping arm, the two free ends exert opposing forces when the two clamping arms are clamping the charcoal block, ensuring the stability of the clamped block and making the lifting operation more reliable.

[0022] This utility model provides a charcoal block lifting tool and hoisting device, which will be described in detail below with reference to specific embodiments.

[0023] like Figure 1 As shown, an embodiment of the present invention provides a charcoal block lifting device 10, including a lifting base 11, two clamping arms 12, and a tensioning assembly 13; the hinged ends of the two clamping arms 12 are respectively hinged to the lifting base 11, and the portion of each clamping arm 12 near its free end bends toward the other clamping arm 12. The two clamping arms 12 are used to swing relative to the lifting base 11 to open or close to each other; the tensioning assembly 13 is disposed on the lifting base 11 and detachably connected to the two clamping arms 12 respectively. The tensioning assembly 13 is used to connect with the two clamping arms 12 so that the two clamping arms 12 are limited to the open state. When the tensioning assembly 13 is separated from the two clamping arms 12, the two clamping arms 12 swing and close under their own weight to clamp the charcoal block 30.

[0024] The specific method of hinge connection between the clamping arm 12 and the lifting base 11 is not limited. For example, the lifting base 11 can have a hinge shaft, and the clamping arm 12 can have a hinge hole that mates with the hinge shaft. Of course, the two clamping arms 12 can share a single hinge shaft to reduce the structural complexity of the lifting device. It should be noted that the hinged end and the free end are the two opposite ends of the clamping arm 12, as shown in the figure below. Figure 1 As shown, the end of the clamping arm 12 connected to the hanger 11 is its hinged end, and the end of the clamping arm 12 away from the hanger 11 is its free end. The portion of each clamping arm 12 near its free end bends towards the other clamping arm 12, for example, as... Figure 1 As shown, the left end of the left clamping arm 12 gradually bends toward the right clamping arm 12, and the right end of the right clamping arm 12 gradually bends toward the left clamping arm 12.

[0025] Furthermore, the two clamping arms 12 can open and close relative to each other during their swinging stroke relative to the suspension seat 11. When the two clamping arms 12 are connected to the tensioning assembly 13 and are in the open state (refer to...), Figure 2 The distance between the free ends of the two clamping arms 12 is slightly greater than the distance between the two clamping points of the carbon block 30. At this time, the two clamping arms 12 will not clamp the carbon block 30. After the two clamping arms 12 are separated from the tensioning assembly 13, as the lifting device is lifted, the two clamping arms 12 can swing and retract under their own weight until the two free ends continuously approach each other to simultaneously clamp the two clamping points of the carbon block 30 (refer to...). Figure 4 At this point, the two clamping arms 12 can hold the carbon block 30. For example... Figure 5 As shown, the charcoal block 30 generally has multiple charcoal bowls 31. The portion of the inner wall surface of two charcoal bowls 31 that is close together is used as the clamping point. That is, the two clamping arms 12 can be used to clamp the inner walls of the two charcoal bowls 31 respectively, so as to realize the clamping of the charcoal block 30 by the lifting device. The specific process can be as follows: Figure 2 As shown, first connect the tensioning assembly 13 to the two clamping arms 12 so that the two clamping arms 12 are limited to the open state, and then use lifting equipment such as an overhead crane to lift the lifting device above the carbon block 30; Figure 3 As shown, the hoist is then lowered so that the free ends of the two clamping arms 12 are inserted into the two charcoal bowls 31. At this time, the free ends of the clamping arms 12 can slightly abut against the bottom of the charcoal bowls 31, and the tensioning assembly 13 is slightly loosened, allowing the operator to release the tensioning assembly 13; Figure 4As shown, the tensioning assembly 13 is then separated from the two clamping arms 12. After separation, the clamping arms 12 are no longer restricted by the tensioning assembly 13. The lifting device is then lifted. During the lifting process, the two clamping arms 12 will swing around the lifting base 11 under their own weight and continuously close together. That is, the free ends of the two clamping arms 12 will gradually move closer to each other, thereby gradually clamping the inner wall surfaces of the two charcoal bowls 31 that are close to each other, and finally clamping the charcoal block 30. Since the charcoal block 30 itself is made of materials such as petroleum coke and pitch coke, its surface is not smooth. Therefore, when clamping the inner wall surface of the charcoal bowl 31, the clamping arms 12 can slightly press into the inner wall surface of the charcoal bowl 31 to ensure effective clamping of the charcoal block 30. Finally, the charcoal block 30 is transported to the designated position by the lifting device. After it is in place, the lifting device is moved down a certain distance relative to the charcoal block 30 to release the clamping state of the clamping arms 12 on the charcoal block 30, thereby releasing the charcoal block 30. Then the tensioning assembly 13 can be reconnected to the clamping arms 12 for secondary lifting.

[0026] In this embodiment, by hinged ends of the two clamping arms 12 to the lifting base 11, and by detachably connecting the tensioning assembly 13 to the lifting base 11 and the two clamping arms 12, the tensioning assembly 13 can switch the state of the two clamping arms 12 by changing its connection with them. Thus, when lifting the charcoal block 30, the tensioning assembly 13 can be connected to the two clamping arms 12 first, allowing the two clamping arms 12 to be inserted into the two charcoal bowls 31 in an open state. After the clamping arms 12 are inside the charcoal bowls 31, the connection between the tensioning assembly 13 and the two clamping arms 12 can be released, and the lifting device can be raised. As the lifting device is raised, the two clamping arms 12 can swing under their own weight. The lifting arm 12 is retracted to clamp the carbon block 30, which is then lifted off along with the lifting device. After the carbon block 30 is in place, the lifting device can be lowered a certain distance relative to the carbon block 30 to release the clamping state of the clamp arm 12, thus releasing the carbon block 30 and completing the lifting operation. Throughout the lifting process, the clamping and releasing operations of the carbon block 30 basically only require raising and lowering the lifting device. Compared to the traditional method of attaching and detaching a steel wire rope from the carbon block 30, this solution simplifies the operation and improves the lifting efficiency of the carbon block 30. Furthermore, because the portion of each clamp arm near its free end bends towards the other clamp arm, the two free ends of the two clamp arms 12 can exert forces in opposite directions when clamping the carbon block 30, ensuring the stability of the carbon block 30 and making the lifting more reliable.

[0027] Optionally, such as Figure 5 and Figure 6 As shown, the upper surface of the charcoal block 30 is provided with a plurality of charcoal bowls 31; when the two clamping arms 12 are restricted to the open state, the distance between the free ends of the two clamping arms 12 matches the distance between the two charcoal bowls 31, so that the free ends of the two clamping arms 12 can be inserted into the two charcoal bowls 31.

[0028] It should be noted that multiple charcoal bowls 31 can be two or more, for example, Figure 5 As shown, there are four charcoal bowls 31, and the four charcoal bowls 31 are arranged sequentially along the length of the charcoal block 30.

[0029] Understandably, after the charcoal blocks 30 are transported to the factory, multiple charcoal blocks 30 are usually stacked on the truck at the same time. The horizontal gap between the charcoal blocks 30 is usually not fixed, and they are generally close to each other. Therefore, it is often necessary to manually pry open the gaps and straighten the charcoal blocks 30 with a crowbar before the steel wire rope can be put around the charcoal blocks 30. This prying process is time-consuming, and the operation of the crowbar may cause personnel to slip and fall due to improper force, thus causing safety hazards. In this solution, the two clamping arms 12 clamp the charcoal blocks 30 by inserting their free ends into the charcoal cups 31 on the upper surface of the charcoal blocks 30, without clamping the circumference of the charcoal blocks 30. This eliminates the need to use a crowbar to straighten the charcoal blocks 30, thus avoiding both the time wasted on the straightening operation and the safety hazards caused by operating the crowbar.

[0030] Optionally, such as Figure 1 and Figure 6 As shown, the free end of the clamping arm 12 is provided with a clamping plate 14, which is used to closely contact the inner wall of the charcoal bowl 31 when the two clamping arms 12 are in the state of clamping the charcoal block 30.

[0031] Specifically, the clamping plate 14 is parallel to the hinge axis of the clamping arm 12, and when the two clamping arms 12 are clamping the carbon block 30, each clamping plate 14 gradually tilts upward in a direction away from the other clamping arm 12. Figure 1 As shown, the hinge axis of the clamping arm 12 is set along the front-back direction (X-axis direction), so the clamping plate 14 can be parallel to the front-back direction.

[0032] In this optional embodiment, by providing a clamping plate 14 at the free end of the clamping arm 12, when the two clamping arms 12 are in the state of clamping the charcoal block 30, the free end of the clamping arm 12 can achieve the clamping effect on the inner wall of the charcoal bowl 31 through the tight abutment between the clamping plate 14 and the inner wall of the charcoal bowl 31; in addition, by making the clamping plate 14 parallel to the hinge axis of the clamping arm 12, and when the two clamping arms 12 are in the state of clamping the charcoal block 30, each clamping plate 14 gradually tilts upward in the direction away from the other clamping arm 12. At this time, the two clamping plates 14 roughly form an inverted figure-eight structure, so that the edges of the two clamping plates 14 abut against the inner walls of the two charcoal bowls 31 respectively, thereby clamping the inner walls of the two charcoal bowls 31 more stably.

[0033] Furthermore, the clamp 14 can be installed on the side of the clamp arm 12 near the other clamp arm 12, that is, on the inner side of the clamp arm 12, so that the clamp 14 can more easily contact the inner wall of the charcoal bowl 31.

[0034] Optionally, such as Figure 5 and Figure 6 As shown, the outline of a portion of the edge of the clamping plate 14 is adapted to the shape of the beveled surface of the charcoal bowl 31. When the two clamping plates 14 are clamping the charcoal block 30, a portion of the edge of the clamping plate 14 is in contact with and abuts against the inner wall of the corresponding charcoal bowl 31.

[0035] It should be noted that the carbon cup 31 is a concave bowl-shaped structure used to install and fix the steel claw, thereby achieving a reliable electrical connection between the carbon block 30 and the conductive steel claw. It should also be noted that the oblique section of the carbon cup 31 is a cross-section of the carbon cup 31 that forms an acute angle with its radial surface, and the profile of the oblique section is the circumferential profile of this cross-section.

[0036] In this optional embodiment, since each clamping plate 14 is in an inclined state when clamping the charcoal block 30, by adapting the contour of a portion of the edge of the clamping plate 14 to the contour shape of the oblique section of the charcoal bowl 31, the contact effect between the clamping plate 14 and the inner wall of the charcoal bowl 31 can be better, thereby enhancing the clamping force of the clamping plate 14 on the inner wall of the charcoal bowl 31.

[0037] Optionally, such as Figure 1 and Figure 5 As shown, the charcoal bowl 31 is a cylindrical countersunk hole, and the shape of part of the edge of the clamping plate 14 is configured as an arc, which is the same as the profile of the oblique section of the cylindrical countersunk hole.

[0038] In this optional embodiment, when the carbon bowl 31 is a cylindrical countersunk hole, the profile shape of the beveled surface of the carbon bowl 31 is arc-shaped. By setting the shape of part of the edge of the clamping plate 14 to arc-shaped, the profile of part of the edge of the clamping plate 14 can be adapted to the profile shape of the beveled surface of the cylindrical countersunk hole.

[0039] Optionally, such as Figure 1 and Figure 6 As shown, some edges of the clamping plate 14 are provided with serrations 141.

[0040] In this optional embodiment, by providing serrations 141 on a portion of the edge of the clamping plate 14, the friction between the portion of the edge of the clamping plate 14 and the inner wall of the charcoal bowl 31 can be increased, effectively preventing the charcoal block 30 from falling off the lifting device and reducing safety hazards.

[0041] Furthermore, the inner wall of the charcoal bowl 31 may be provided with a spiral groove 311 extending spirally along its axis, which can increase the roughness of the inner wall of the charcoal bowl 31, thereby further increasing the friction between the edge of the clamping plate 14 and the inner wall of the charcoal bowl 31 when they come into contact.

[0042] Optionally, such as Figure 1 As shown, the carbon block lifting device 10 also includes a fixing plate 15, which is fixed to the free end of the clamping arm 12; the clamping plate 14 is attached to the side of the fixing plate 15 near the other clamping plate 14 and is detachably connected to the fixing plate 15.

[0043] Specifically, the clamping plate 14 and the fixing plate 15 can be detachably connected by bolts.

[0044] It is understandable that when the clamping plate 14 clamps the inner wall of the charcoal bowl 31, the clamping plate 14 will be subjected to the force from the clamping arm 12. Therefore, in this optional embodiment, by fixing a fixing plate 15 at the free end of the clamping arm 12 and attaching the clamping plate 14 and the fixing plate 15 to the side of the clamping plate 14, the fixing plate 15 can distribute the force on the clamping plate 14, thereby reducing the deformation of the clamping plate 14. Furthermore, since the serrations 141 on the edge of the clamping plate 14 are prone to wear and failure, in this optional embodiment, by detachably connecting the clamping plate 14 and the fixing plate 15, the clamping plate 14 can be quickly replaced when the serrations 141 wear and fail, ensuring the convenience of replacing the clamping plate 14.

[0045] Optionally, such as Figure 7 As shown, the clamping arm 12 is provided with a pull ring 121; the tensioning assembly 13 has two connecting ends, and each of the two connecting ends is provided with a hook 131. The hooks 131 on the two connecting ends are used to hook and pull in corresponding ways with the pull rings 121 on the two clamping arms 12.

[0046] In this optional embodiment, by hooking and engaging the hook 131 with the pull ring 121, a detachable connection can be achieved between the tensioning assembly 13 and the clamping arm 12. Because the hook 131 and the pull ring 121 are used to achieve a detachable connection, it is convenient to hook and unhook the hook 131 and the pull ring 121. This helps the tensioning assembly 13 and the clamping arm 12 to be quickly connected and separated, thereby further improving the hoisting efficiency of the carbon block 30.

[0047] Optionally, such as Figure 7 As shown, the hanging bracket 11 has a mounting hole 111; the tensioning assembly 13 includes a pull rope 132 and a limiting member 133. The pull rope 132 passes through the mounting hole 111, and the two ends of the pull rope 132 correspond to form two connecting ends. The two limiting members 133 are spaced apart from the pull rope 132 along the extension direction of the pull rope 132, and respectively abut against the two ends of the hanging bracket 11 along the axial direction of the mounting hole 111.

[0048] Specifically, the limiting component 133 can be a limiting block or a limiting plate.

[0049] In this optional embodiment, the pull rope 132 passes through the mounting hole 111, and the two ends of the pull rope 132 form two connecting ends. That is, the tensioning assembly 13 can connect two clamping arms 12 simultaneously with the help of a single pull rope 132, which is simple in structure and easy to install. Furthermore, since the pull rope 132 itself is flexible, when the clamping plate 14 enters the carbon bowl 31 and abuts against the wall of the carbon bowl 31, the pull rope 132 can be slightly loosened to avoid the clamping plate 14 rigidly impacting the wall of the carbon bowl 31 and causing deformation. In addition, due to the two limiting... Positioning members 133 are spaced apart along the extension direction of the pull rope 132 and respectively abut against the two ends of the lifting seat 11 along the axial direction of the mounting hole 111. Therefore, due to the abutment relationship between the two positioning members 133 and the two sides of the lifting seat 11, the positioning members 133 will not be displaced relative to the lifting seat 11 (in the Y-axis direction), thereby preventing the pull rope 132 from deviating relative to the lifting seat 11. This ensures the symmetry of the positions of the two clamping arms 12 relative to the lifting seat 11, making the process of lifting the carbon block 30 more stable and reducing safety hazards.

[0050] In some other embodiments, the tensioning assembly 13 may include two pull ropes 132, one end of which is fixed to the hanging base 11, and the other end of which forms two connecting ends, that is, the tensioning assembly 13 is connected to the two clamping arms 12 by means of the two pull ropes 132.

[0051] like Figure 8 and Figure 9 As shown in the figure, an embodiment of the present invention provides a hoisting device, including the carbon block hoisting device 10 as described above.

[0052] It should be noted that there can be one or more charcoal block lifting devices 10.

[0053] In this embodiment, since the hoisting device includes the aforementioned charcoal block hoist 10, it possesses all the beneficial effects of all embodiments of the aforementioned charcoal block hoist 10, which will not be elaborated here.

[0054] Optionally, such as Figure 8 and Figure 9 As shown, it also includes a lifting beam 20, which is used to connect lifting equipment; there are two carbon block lifting devices 10, which are connected to the lifting beam 20 at intervals, and the distance between the two carbon block lifting devices 10 is adapted to the distance between the carbon bowls 31 on the two adjacent carbon blocks 30.

[0055] Specifically, the lifting base 11 of the charcoal block lifting device 10 may be equipped with a connecting shaft 112, and the lifting beam 20 may be equipped with a connecting hole 21. The lifting device and the lifting beam 20 are connected by the connecting shaft 112 cooperating with the connecting hole 21. It should be noted that the lifting equipment can be an overhead crane.

[0056] In this embodiment, since the lifting beam 20 is used to connect the lifting equipment, and the two carbon block lifting devices 10 are spaced apart on the lifting beam 20, that is, the two carbon block lifting devices 10 can be connected to the lifting equipment simultaneously through the lifting beam 20, and each carbon block lifting device 10 can lift one carbon block 30. In other words, this lifting device can lift two carbon blocks 30 at the same time, which can greatly improve the efficiency of lifting carbon blocks 30. Furthermore, since the distance between the two carbon block lifting devices 10 is adapted to the distance between the carbon bowls 31 on the two adjacent carbon blocks 30, when this lifting device lifts two carbon blocks 30 at the same time, the sides of the two carbon blocks 30 can rub against each other, thereby improving the reliability of lifting.

[0057] Optionally, such as Figure 8 and Figure 9 As shown, the two carbon block lifting devices 10 are respectively connected to the two ends of the lifting beam 20; the lifting beam 20 is provided with a first lifting ring 22 and two second lifting rings 23 for connecting the lifting equipment, the first lifting ring 22 is located in the middle of the lifting beam 20, and the two second lifting rings 23 are respectively located at the two ends of the lifting beam 20.

[0058] It should be noted that the lifting equipment can be connected to the first lifting ring 22 or the two second lifting rings 23 via a lifting rope, such as a wire rope. Specifically, when the lifting rope is connected to the first lifting ring 22, the lifting rope can pass through the first lifting ring 22; when the lifting rope is connected to the two second lifting rings 23, the lifting rope can pass through the two second lifting rings 23 sequentially. It should also be noted that when the lifting seat 11 of the carbon block lifting device 10 is equipped with a connecting shaft 112, the lifting equipment can be connected to the lifting ring via a lifting rope, or it can be directly connected to the connecting shaft 112 via a lifting rope; there are no restrictions here.

[0059] In this optional embodiment, since the lifting beam 20 is provided with both a first lifting ring 22 for connecting the lifting equipment and two second lifting rings 23 for connecting the lifting equipment, the other lifting ring can be used as a backup when any one type of lifting ring fails, avoiding the need to replace the entire lifting device and ensuring the progress of the lifting operation. In addition, since the first lifting ring 22 is located in the middle of the lifting beam 20 and the two second lifting rings 23 are located at both ends of the lifting beam 20, that is, the connection point between the lifting equipment and the lifting beam 20 is located in the middle or at both ends of the lifting beam 20, which can ensure the stability of the lifting operation.
