Description

Technical Field

[0001] This invention relates to the field of material handling technology, specifically to a residual electrode stack lifting machine. Background Technology

[0002] After electrolysis, copper anode plates produce residual plates. To ensure copper recovery, these residual plates are typically recycled back into the furnace for further smelting. Specifically, the residual plates are then washed, packed into stacks, and transported to the pyrometallurgical workshop for resmelting. In related technologies, the residual plate stacks are mainly lifted into the furnace using a vertical elevator. However, the high lifting height required for the residual plate stacks makes the elevator operation unstable. Summary of the Invention

[0003] This application is based on the inventor's discoveries and understanding of the following facts and problems:

[0004] The bottom of the residual electrode stack elevator is the loading position, where a forklift places the residual electrode stack onto the elevator. The middle of the residual electrode stack elevator is equipped with a shaping position and a shaping device to shape the residual electrode stack, making it neat and positioned in the middle of the lifting frame, so that the lifting and furnace charging devices can smoothly charge the residual electrode stack into the furnace. The upper part of the residual electrode stack elevator is equipped with a furnace charging position and a furnace charging device to push the residual electrode stack into the furnace mouth of a smelting furnace, such as a blowing furnace.

[0005] Because the furnace opening of the blowing furnace is relatively high, the residual electrode stack needs to be lifted to a higher position. Due to manufacturing errors or deformation during use, the gap between the hoist's track surfaces is relatively large. This causes a large variation in the gap between the guide wheels and the guide rail surfaces of the hoist during operation, resulting in swaying of the hoist during operation. At the same time, the hoist is subjected to horizontal forces during the shaping and furnace loading processes, making the swaying even more pronounced. This causes the relative positions of the limit switch blocks on the hoist and the limit switches on the frame to frequently change, resulting in inaccurate positioning of the hoist at various workstations. In some cases, the blocks may not even touch the limit switches, affecting the operation of the hoist.

[0006] The present invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of the present invention provide a residual electrode stack lifting machine.

[0007] The residual electrode stack lifting machine according to an embodiment of the present invention includes:

[0008] A frame, on which guide rails and a hoisting device are provided;

[0009] A lifting frame is connected to the winch device to be driven by the winch device to move up and down along the frame. The lifting frame is provided with guide wheels, which abut against the guide rail to guide the lifting frame to move up and down relative to the frame.

[0010] An adjustment mechanism is provided, comprising an adjustment component and a guide plate. The adjustment component is installed at a predetermined position on the guide rail and is connected to the guide plate to adjust the position of the guide plate. When the guide wheel moves past the predetermined position, the guide plate abuts against the guide wheel to guide it.

[0011] According to an embodiment of the present invention, the residual electrode stacking elevator, by setting an adjustment mechanism on the guide rail, ensures that when the guide wheel on the lifting frame moves to a designated position, the guide wheel and the guide rail of the lifting frame remain within a stable distance range, thereby ensuring the stability of the guide rail operation, limiting the swaying amplitude of the lifting frame, and improving the operational stability of the equipment.

[0012] In an embodiment of the present invention, the guide rail includes a first plane and a second plane that are perpendicular to each other, and the guide wheel includes a first guide wheel that abuts against the first plane and a second guide wheel that abuts against the second plane.

[0013] In this embodiment of the invention, the adjustment mechanism includes a first guide plate parallel to the first plane and a second guide plate parallel to the second plane.

[0014] In this embodiment of the invention, the cross-sectional shape of the guide rail is "H".

[0015] In this embodiment of the invention, the number of the adjustment mechanisms is multiple.

[0016] In this embodiment of the invention, a charging device is provided at the bottom of the guide rail, a shaping device is provided in the middle of the guide rail, and a furnace-feeding device is provided at the top of the guide rail. The adjustment mechanism is provided at least near the charging device, the shaping device, and the furnace-feeding device on the guide rail.

[0017] In this embodiment of the invention, the guide rail is provided with mounting holes or mounting grooves, and the guide plate is located in the mounting holes or mounting grooves.

[0018] In this embodiment of the invention, a first inclined surface is provided in the mounting hole or the mounting groove, and a second inclined surface is provided on the guide plate, with the first inclined surface abutting against the second inclined surface.

[0019] In this embodiment of the invention, the adjusting component includes a mounting plate and a bolt. The mounting plate is fixedly connected to the frame, the bolt passes through the mounting plate, and one end of the bolt is fixedly connected to the guide plate.

[0020] In this embodiment of the invention, a stop block is provided on the lifting frame, and a limit switch is provided on the frame. The stop block is used to touch the limit switch to control the movement of the lifting frame. Attached Figure Description

Detailed Implementation

[0031] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] The following is for reference. Figures 1 to 8 A residual electrode stack lifting machine according to an embodiment of the present invention is described.

[0033] like Figures 1 to 8 As shown, the residual electrode stacking elevator according to an embodiment of the present invention includes a frame, a lifting frame, and an adjustment mechanism.

[0034] The frame 1 is a vertically oriented frame structure, with its bottom fixedly installed on a fixed foundation such as the ground or platform. A hoisting device 12 is installed on the top of the frame 1. A guide rail 11 is arranged vertically on the frame 1. The guide rail 11 can be part of the frame 1 itself, or it can be a relatively independent guide rail 11 that is fixedly installed on the frame 1.

[0035] The lifting frame 2 is equipped with guide wheels 21, which abut against the guide rail 11 to guide the lifting frame 2 in raising and lowering relative to the frame 1 and to limit the horizontal movement of the lifting frame 2 relative to the frame 1. The lifting frame 2 is connected to a winch 12 to be driven by the winch 12 to raise and lower along the frame 1. For example, the winch 12 is an electric hoist, with a steel wire wound on a drum, and the other end of the steel wire rope fixedly connected to the lifting frame 2. The rotation of the drum drives the lifting frame 2 to move up and down through the steel wire rope. Of course, other common mechanisms for lifting heavy objects can also be used in this invention, such as various types of winches.

[0036] Adjustment mechanism 3 is used to replace guide rail 11 at a designated position to guide guide wheel 21. Adjustment mechanism 3 includes adjustment component 31 and guide plate 32. Adjustment component 31 is installed at a predetermined position on guide rail 11. Adjustment component 31 is connected to guide plate 32 to adjust the position of guide plate 32. Guide plate 32 has a guiding position and a non-guiding position before and after adjustment. When guide plate 32 is in the guiding position, guide plate 32 stops guide wheel 21 when guide wheel 21 moves through the predetermined position to guide guide wheel 21. When guide plate 32 is in the non-guiding position, guide rail 11 stops guide wheel 21 when guide wheel 21 moves through the predetermined position to guide guide wheel 21.

[0037] According to an embodiment of the present invention, the residual electrode stacking elevator, by setting an adjustment mechanism on the guide rail, ensures that when the guide wheel on the lifting frame moves to a designated position, the guide wheel and the guide rail of the lifting frame remain within a stable distance range, thereby ensuring the stability of the guide rail operation, limiting the swaying amplitude of the lifting frame, and improving the operational stability of the equipment.

[0038] In this embodiment of the invention, the guide rail 11 guides the guide wheels 21 in two directions. The guide rail 11 includes a first plane 111 and a second plane 112 that are perpendicular to each other. Correspondingly, the guide wheels 21 on the lifting frame 2 include a first guide wheel 211 that abuts against the first plane 111 and a second guide wheel 212 that abuts against the second plane 112. By having the guide wheels 21 in two mutually perpendicular directions abut against the guide rail 11, the stability of the lifting frame 2 during operation can be increased.

[0039] Furthermore, for the guide rail 11, which includes a first plane 111 and a second plane 112 that are perpendicular to each other, the corresponding adjustment mechanism 3 includes a first guide plate 321 parallel to the first plane 111 and a second guide plate 322 parallel to the second plane 112. When the first guide plate 321 is in the guiding position, it abuts against the first guide wheel 211 to guide it when the guide wheel 21 moves past a predetermined position; when the second guide plate 322 is in the guiding position, it abuts against the second guide wheel 212 to guide it when the guide wheel 21 moves past a predetermined position.

[0040] In this embodiment of the invention, the cross-sectional shape of the guide rail 11 is "H" shaped, but the cross-sectional shape of the guide rail 11 can also be "T" shaped or "L" shaped, etc.

[0041] In this embodiment of the invention, there are multiple adjusting mechanisms 3. Multiple adjusting mechanisms 3 can be arranged at the same height; for example, when there are multiple guide rails 11, each guide rail 11 is provided with an adjusting mechanism 3. Alternatively, multiple adjusting mechanisms 3 can be arranged at different heights; for example, multiple designated positions are preset along the vertical direction on the frame 1, and adjusting mechanisms 3 are arranged at each of these designated positions. It is understood that when adjusting mechanisms 3 are arranged at designated positions at different heights, there can also be multiple adjusting mechanisms 3 at the same height.

[0042] In this embodiment of the invention, in order to improve the efficiency of the residual anode stack blowing, the residual anode stack elevator is also provided with a loading device 13 located at the bottom of the guide rail 11, a shaping device 14 located in the middle of the guide rail 11, and a furnace charging device 15 located at the top of the guide rail 11.

[0043] The charging device 13 is located at the bottom of the elevator, using handling machinery to stack the scrap plates onto the elevator, or directly placing the stacked scrap electrode stacks onto the elevator. The shaping device 14 is located between the bottom and top of the elevator, using robotic arms or other shaping machinery to adjust the shape of the scrap electrode stacks. The furnace-feeding device 15 is located at the top of the elevator; after the scrap electrode stacks are lifted to the top, the furnace-feeding device 15 pushes the scrap electrode stacks into the furnace mouth of a blowing furnace or other smelting furnace. Since the charging device 13, shaping device 14, and furnace-feeding device 15 all apply horizontal forces to the scrap electrode stacks or the lifting frame 2, the lifting frame 2 will experience horizontal movement. Adjusting mechanisms 3 are installed at the locations of these devices to reduce the horizontal movement of the lifting frame 2 and improve its operational stability.

[0044] In this embodiment of the invention, the guide rail 11 is provided with mounting holes or mounting grooves, and the guide plate 32 is located in the mounting holes or mounting grooves.

[0045] For example, such as Figure 6 or Figure 8As shown, a mounting groove is provided on the guide rail 11, and the guide plate 32 is disposed in the mounting groove, with the depth of the mounting groove being greater than the thickness of the guide plate 32. In the non-guided position, the guide plate 32 is completely retracted into the mounting groove, so that the plane of the guide plate 32 used to stop the guide wheel 21 is lower than the plane of the guide rail 11 used to stop the guide wheel 21. When the guide wheel 21 moves to this position, it only contacts the guide rail 11, and the adjusting mechanism 3 is inactive. In the guided position, the adjusting component 31 is adjusted so that the guide plate 32 moves outward until the plane of the guide plate used to stop the guide wheel 21 protrudes from the mounting groove, i.e., the plane of the guide plate 32 used to stop the guide wheel 21 is higher than the plane of the guide rail 11 used to stop the guide wheel 21. When the guide wheel 21 moves to this position, it only contacts the guide plate 32.

[0046] For example, such as Figure 7 As shown, the guide rail 11 is provided with mounting holes. When the position of the guide plate 32 is changed by adjusting the adjusting component 31, the guide plate 32 can pass through the mounting holes. In the non-guided position, the plane of the guide plate 32 used to stop the guide wheel 21 is located to the left of the plane of the guide rail 11 used to stop the guide wheel 21 (the guide wheel 21 is located to the right of the guide rail 11). When the guide wheel 21 moves to this position, it only contacts the guide rail 11, and the adjusting mechanism 3 does not function. In the guided position, the plane of the guide plate 32 used to stop the guide wheel 21 is located to the right of the plane of the guide rail 11 used to stop the guide wheel 21. When the guide wheel 21 moves to this position, it only contacts the guide plate 32.

[0047] Furthermore, such as Figure 5 As shown, a first inclined surface is provided in the mounting hole or mounting groove, and a second inclined surface is provided on the guide plate 32. The first inclined surface abuts against the second inclined surface. The first and second inclined surfaces contact each other and play a positioning role, so that the guiding position of the guide plate 32 is relatively fixed, which is suitable for some residual pole stack lifting machines with relatively stable adjustment distance.

[0048] In embodiments of the present invention, such as Figure 7 As shown, the adjusting component 31 includes a mounting plate and bolts. The mounting plate is fixedly connected to the frame 1, and the bolts pass through the mounting plate. One end of the bolts is fixedly connected to the guide plate 32 by a nut. When the guide plate 32 needs to be adjusted, first loosen the nut between the bolt and the mounting plate, then adjust the position of the bolt relative to the mounting plate, and thus adjust the position of the guide plate 32. After the guide plate 32 is adjusted to the correct position, tighten the nut between the bolt and the mounting plate to complete the adjustment.

[0049] In this embodiment of the invention, a stop block 16 is provided on the lifting frame 2, and a limit switch is provided on the frame 1. The stop block 16 is used to touch the limit switch to control the movement of the lifting frame 2.

[0050] The following reference Figures 1 to 4 A residual electrode stack lifting machine according to a specific example of the present invention is described.

[0051] Example 1

[0052] like Figures 1 to 4 As shown, the residual electrode stack lifting machine in this embodiment includes a frame 1 arranged vertically. The frame 1 is a cuboid frame structure with four guide rails 11 arranged vertically along its four edges. The cross-sectional shape of each guide rail 11 is "H"-shaped, and it has a first plane 111 and a second plane 112 that are perpendicular to each other. Correspondingly, the guide wheels 21 on the lifting frame 2 include a first guide wheel 211 that abuts against the first plane 111 and a second guide wheel 212 that abuts against the second plane 112. The frame 1 is also provided with a feeding device 13 located at the bottom of the guide rail 11, a shaping device 14 located in the middle of the guide rail 11, and a furnace feeding device 15 located at the top of the guide rail 11. Adjustment mechanisms 3 are provided near these devices on the guide rail 11.

[0053] The adjustment mechanism 3 includes a first guide plate 321 and a second guide plate 322. The guide rail 11 has a mounting groove for mounting the first guide plate 321 and a mounting hole for mounting the second guide plate 322. When in the non-guided position, the plane of the first guide plate 321 that abuts against the first guide wheel 211 is parallel to the first plane 111, and the plane of the second guide plate 322 that abuts against the second guide wheel 212 is located below or parallel to the second plane 112 in the figure. At this time, the first guide wheel 211 abuts against the first plane 111, and the second guide wheel 212 abuts against the second plane 112. When in the guided position, the plane of the first guide plate 321 that abuts against the first guide wheel 211 is located to the left of the first plane 111 in the figure, and the plane of the second guide plate 322 that abuts against the second guide wheel 212 is located above the second plane 112 in the figure. At this time, the first guide wheel 211 abuts against the first guide plate 321, and the second guide wheel 212 abuts against the second guide plate 322.
