Description

Technical Field

[0001] This utility model relates to the field of electrolytic zinc, specifically to a plate-type hook for electrolytic zinc lifting equipment. With the increase in production capacity and efficiency, large electrode plates of 3.2 square meters are gradually being widely used. The special lifting equipment for large electrode plates in the loading tank enables the transport and transfer of large electrode plates between the conveyor lines of the electrolytic cell, zinc stripping unit, and anode machine, and is the most core equipment in the zinc electrowinning workshop.

[0002] Zinc electrowinning lifting equipment needs to lift the cathode / anode plates from an electrolytic cell in batches according to process requirements. In most zinc electrowinning workshops today, U-shaped bolt-type hooks are used. For example... Figure 1 As shown in the schematic diagram of the existing hook structure, the current hook adopts a U-bolt type hook 10. Each hook 10 is fixed to the bottom surface of the lifting device's movable beam 6 by four nuts 101, two flat washers 102, and two spring washers 103. Because a large number of anode / cathode plates are lifted at one time, one set of U-bolt type hooks requires tightening four sets of nuts, and each set of hooks needs to be installed one by one, which is a very large workload. Moreover, the different degrees of tightening of each nut during installation make it impossible to guarantee the height of the hook. In addition, the U-bolt type hook is also prone to deformation during use. Background Technology

[0003] Currently, in zinc electrowinning workshops, lifting equipment is mainly used for loading and unloading anode and cathode plates. Utility Model Content

[0004] To address the technical problems of large installation workload and inaccurate installation height of existing U-bolt hooks, this utility model provides a plate hook for electrolytic zinc lifting equipment.

[0005] A plate hook for electrolytic zinc lifting equipment includes a movable beam for the lifting equipment. The bottom of the movable beam is provided with a convex mounting platform. Multiple plate hooks are provided on the side of the convex mounting platform along its length. Each plate hook includes a mounting part and a U-shaped hanging plate position located below the mounting part. The mounting part of the plate hook is connected to the convex mounting platform by bolts and slotted nuts.

[0006] In a preferred embodiment of the plate hook for electrolytic zinc lifting provided by this utility model, a cotter pin is provided at the end of the bolt near the slotted nut.

[0007] In a preferred embodiment of the plate hook for electrolytic zinc lifting provided by this utility model, the plate hook includes a plate cathode hook and a plate anode hook, which are respectively disposed on opposite sides of the convex mounting platform; the plate cathode hook and the plate anode hook are connected to the convex mounting platform by the same bolt and the slotted nut.

[0008] In a preferred embodiment of the plate-type hook for electrolytic zinc lifting provided by this utility model, two U-shaped hanging plate positions are provided below the mounting part of the plate-type anode hook.

[0009] In a preferred embodiment of the plate-type hook for electrolytic zinc lifting provided by this utility model, three U-shaped hanging plate positions are provided below the mounting part of the plate-type cathode hook.

[0010] In a preferred embodiment of the plate-type hook for electrolytic zinc lifting provided by this utility model, the inner bottom of the U-shaped hanging plate position of the plate-type cathode hook is groove-shaped.

[0011] In a preferred embodiment of the plate-type hook for electrolytic zinc lifting provided by this utility model, the inner bottom of the U-shaped hanging plate position of the plate-type anode hook is arc-shaped.

[0012] Compared to existing technologies, the plate-type hook for electrolytic zinc lifting provided by this utility model uses the two opposite sides of the convex mounting platform as precise positioning surfaces, making its installation faster and simpler. The plate-type cathode hook and plate-type anode hook share bolts and slotted nuts during installation, greatly reducing the amount of installation work.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please refer to the following: Figures 2 to 5 These are schematic diagrams of a plate-type hook for electrolytic zinc lifting, a plate-type anode hook, a plate-type cathode hook, and a double-row installation, respectively, provided by this utility model.

[0022] Example 1

[0023] The aforementioned plate hook for electrolytic zinc lifting includes a lifting movable beam 6, the bottom of which is provided with a convex mounting platform 61, and multiple plate hooks 1 are provided on the opposite sides of the convex mounting platform along the length direction.

[0024] The plate-type hook 1 includes a plate-type anode hook 11 and a plate-type cathode hook 12. Both the plate-type anode hook 11 and the plate-type cathode hook 12 include a mounting part and a U-shaped hanging plate position provided below the mounting part.

[0025] The plate anode hook 11 has a U-shaped hanging plate position at each end of its mounting portion. The inner bottom of the U-shaped hanging plate position of the plate anode hook 11 is arc-shaped. The plate anode hook 11 is a one-piece structure.

[0026] The plate cathode hook 12 has a U-shaped hanging plate position at each end and below the center of its mounting portion. The inner bottom of the U-shaped hanging plate position of the plate cathode hook 12 is groove-shaped. The plate cathode hook 12 is an integral structure.

[0027] The plate-type anode hook 11 and the plate-type cathode hook 12 are disposed opposite to each other on the two sides of the convex mounting platform 61. The mounting portions of the plate-type anode hook 11 and the plate-type cathode hook 12 are jointly fixed to the convex mounting platform 61 by the same bolt 2 and slotted nut 4. A cotter pin 5 is provided at the end of the bolt 2 near the slotted nut 4. A washer 3 is provided between the slotted nut 4 and the plate-type hook 1. In this embodiment, the plate-type anode hook 11 and the plate-type cathode hook 12 are fixed by two sets of bolts 2 and slotted nuts 4. During specific installation, the number of bolts 2 and slotted nuts 4 can be increased or decreased as needed.

[0028] For specific implementation details, please refer to [link / reference]. Figure 7 This is a working principle diagram of a plate hook for electrolytic zinc lifting equipment provided by this utility model.

[0029] The drive assembly on the lifting device drives the two sets of lifting device movable beams 6 to move closer or further apart along the guide shaft, thereby causing the plate anode hook 11 and the plate cathode hook 12 mounted on the lifting device movable beams 6 to move closer or further apart. The plate cathode hook 12 is located on the side where the two sets of lifting device movable beams 6 are closer together, and the plate anode hook 11 is located on the side where they are further apart.

[0030] When the two sets of lifting beams 6 approach each other, the plate cathode hook 12 gradually approaches the inner side of the lifting lug of the cathode plate 8, so that the lifting lug of the cathode plate 8 enters the U-shaped hanging plate position of the plate cathode hook 12, thus completing the hanging of the cathode plate 8.

[0031] When the two sets of lifting beams 6 move away from each other, the plate anode hook 11 gradually approaches the inner side of the lifting lug of the anode plate 7, so that the lifting lug of the anode plate 7 enters the U-shaped hanging plate position of the plate anode hook 11, thus completing the hanging of the anode plate 7.

[0032] Example 2

[0033] Please refer to the following: Figure 6 This is a schematic diagram of a single-row installation of a plate hook for an electrolytic zinc lifting device provided by this utility model.

[0034] The difference between Embodiment 2 and Embodiment 1 is that the plate anode hook 11 and the plate cathode hook 12 are arranged opposite each other on both sides of the convex mounting platform 61, instead of mounting the plate anode hook 11 or the plate cathode hook 12 on one side of the convex mounting platform 61. That is, the double-row installation is changed to a single-row installation to adapt to the different production process requirements of the zinc electrolysis workshop.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
