[0018] 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.

[0019] Example 1

[0020] Please refer to the following: Figures 1 to 3 These are schematic diagrams of the electrolytic zinc large electrode plate lifting device provided by this utility model from different perspectives, and a schematic diagram of the electrolytic zinc large electrode plate lifting device when suspending the cathode plate and anode plate.

[0021] The electrolytic zinc large electrode plate lifting device includes a lifting bracket 1, and the top of the lifting bracket 1 is provided with four sets of movable pulleys 5. The movable pulleys 5 are connected to an external lifting device through steel wire ropes to realize lifting.

[0022] The bottom of the lifting bracket 1 is equipped with a positioning sensor 20.

[0023] The top of both ends of the lifting bracket 1 are provided with guide end face rollers 14 and guide side rollers 13. The axes of the guide end face rollers 14 and the guide side rollers 13 are perpendicular to each other; guide posts 15 are also provided at both ends of the lifting bracket 1, and the guide end face rollers 14 and the guide side rollers 13 roll along the sides of the guide posts 15 during the lifting and lowering of the lifting bracket 1. In this embodiment, in Figure 2 From the perspective of the guide end face rollers 14, there are four rollers. During the lifting and lowering process, two rollers slide up and down along the upper side of the guide post 15, and two rollers slide up and down along the lower side of the guide post 15. There is one guide side roller 13, which slides up and down along the side of the guide post 15 that is close to it.

[0024] The lifting bracket 1 has positioning brackets 3 at its bottom diagonally at both ends, and each positioning bracket 3 has a positioning hole at its bottom. A positioning cone 4, corresponding to the positioning hole, is located below each positioning hole. When the lifting bracket 1 descends, the positioning cone 4 inserts into the positioning hole to complete the positioning.

[0025] The lifting bracket 1 is provided with a slidable fixing frame 9 below it, which is driven to slide by a sliding drive device. The fixing frame 9 includes a left fixing frame 91, a middle fixing frame 92, and a right fixing frame 93. Each of the left fixing frame 91, the middle fixing frame 92, and the right fixing frame 93 has four slide rails at its top, and the bottom of the lifting bracket 1 has transverse rollers 6 adapted to the slide rails 7. The sliding drive device includes a first electric push rod 8 arranged along the sliding direction of the fixing frame. The fixed end of the first electric push rod 8 is fixedly connected to the lifting bracket 1, and the movable end is fixedly connected to the middle fixing frame 92.

[0026] The mounting bracket 9 is provided with a main shaft 12 rotatably connected to the mounting bracket 9 and a rotation drive device for driving the main shaft 12 to rotate. The main shaft 12 includes three sub-spindles; the three sub-spindles are respectively rotatably connected to the left mounting bracket 91, the middle mounting bracket 92 and the right mounting bracket 93, and adjacent sub-spindles are shaft connected.

[0027] The rotation drive device includes a second electric push rod 10 and a push fork 19 arranged along a sliding direction perpendicular to the fixed frame. The fixed end of the second electric push rod is hinged to the middle fixed frame 92, the movable end is hinged to one end of the push fork 19, and the other end of the push fork 19 is fixedly connected to the main shaft 12.

[0028] The main shaft 12 is equipped with a crank mechanism 18, which connects two movable beams 2. Each movable beam 2 includes a left movable beam 21, a middle movable beam 22, and a right movable beam 23. Each sub-spindle section has two crank mechanisms 18. Each crank mechanism 18 is Z-shaped, with its upper and lower parts hinged to the middle part. The center of each crank mechanism 18 is fixed to the sub-spindle, and its two ends are hinged to the two movable beams 2 respectively. In this embodiment, the sub-spindle at the left fixed frame 91 has two crank mechanisms 18. One end of each crank mechanism 18 is hinged to one left movable beam 21, and the other end is hinged to another left movable beam 21. The crank mechanisms 18 at the middle fixed frame 92 and the right fixed frame 93 are similar to those at the left fixed frame 91 and will not be described further.

[0029] The fixed frame 9 is provided with a secondary shaft 11, the axis of which is perpendicular to the axis of the main shaft 12. The movable beam 2 is movably sleeved on the secondary shaft 11. In this embodiment, the left fixed frame 91 is provided with three secondary shafts 11, and the two left movable beams 21 are respectively movably sleeved on the three secondary shafts 11. The secondary shafts 11 at the middle fixed frame 92 and the right fixed frame 93 are similar to those at the left fixed frame 91, and will not be described again.

[0030] The bottom of the movable beam 2 is provided with multiple hooks corresponding to each other along the length of the movable beam. The hooks include cathode hooks 17 and anode hooks 16. The cathode hooks 17 are correspondingly located on the sides of the bottom of the two movable beams 2 that are close to each other. The anode hooks 16 are correspondingly located on the sides of the bottom of the two movable beams 2 that are far apart from each other.

[0031] In specific implementation, lifting and positioning: The external lifting mechanism drives the lifting device to rise and fall via the movable pulley block 5. The guide end face rollers 14 and guide side rollers 13 at both ends of the lifting bracket 1 rise and fall along the guide column 15. When it descends to a certain position, the positioning hole enters the positioning cone 4, completing the mechanical positioning of the lifting device. The lifting device continues to descend, stopping when the positioning sensor frame 20 reaches the conductive beam of the anode and cathode plates, at which point the hook plate position is obtained.

[0032] Lateral movement of the lifting device: The first electric push rod 8 extends or retracts, causing the fixed frame 9 installed on it to move laterally left and right relative to the lifting bracket 1, giving the lifting device three positions: "+", "0", and "-". This allows for the batch lifting of cathode plates 102 or anode plates 101. When lifting cathode plates 102, the process requirement of lifting each tank's cathode plates 102 twice is met; when lifting anode plates 101, the process requirement of lifting each tank's anode plates 101 three times is met.

[0033] Lifting device opening and closing: The second electric push rod 10 extends or retracts, pushing the push fork 19 to swing back and forth, causing the main shaft 12 to rotate clockwise or counterclockwise, thereby causing the movable beams 2 to move closer or further apart on the secondary shaft 11, so that the anode hook 16 engages / disengages from the conductive beam lug on the anode plate 101, or the cathode hook engages / disengages from the conductive beam lug on the cathode plate 102. When the lifting device is opened and closed, three positions are available: cathode position, neutral position, and anode position. In the anode position, the conductive beam lug of the anode plate 101 is located within the anode hook 16; in the cathode position, the conductive beam lug of the cathode plate 102 is located within the anode hook 16; in the neutral position, neither the anode plate 101 nor the anode plate 102 is engaged / disengaged.

[0034] The cathode plate 102 or anode plate 101 is removed from the loading slot and transported by lifting, lateral movement and opening and closing of the lifting device.

[0035] It should be noted that the number of stations during the lateral movement of the lifting device can be changed according to actual needs and the number of batch lifting operations, and different spacings of adjacent cathode hooks and adjacent anode hooks can be used. In this embodiment, the lifting operations at the "+", "0", and "-" stations are as follows: When lifting anode plate 101, due to its weight, it is lifted in three stages; when at the "-" station, anode plates "1, 4, 7..." are lifted; when at the "0" station, anode plates "2, 5, 8..." are lifted; and when at the "+" station, anode plates "3, 6, 9..." are lifted. Cathode plates can be lifted in two stages; when at the "-" station, cathode plates "1, 3, 5,..." are lifted; and when at the "+" station, anode plates "2, 5, 8..." are lifted.

[0036] Example 2

[0037] The main difference between Embodiment 2 and Embodiment 1 is that the three-section configuration of the fixing frame 9 is combined into a single unit, the three-section configuration of the movable beam 2 is combined into a single unit, and the three-section configuration of the main shaft 12 is combined into a single unit. While this single-unit configuration allows for the accurate and reliable lifting of multiple large electrode plates in batches, and also accommodates the lifting of both cathode and anode plates, it makes the electrode plates more susceptible to uneven stress during suspension, and the movable beam 2 is more prone to deformation.

[0038] 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.
