Description

Technical Field

[0001] The utility model relates to the technical field of cathode plate hoisting, in particular to a hooking device for cathode plate hoisting. Background Art

[0002] In the electrolysis industry, the lifting and installation of cathode plates is a critical link between the electrolysis process and subsequent manufacturing processes. After electrolysis, the cathode plates, having absorbed a large amount of electrolysis products, significantly increase in weight, and their shape and size may vary depending on the electrolysis process. Therefore, ensuring the safe, stable, and efficient lifting of cathode plates during the lifting process has become a pressing technical challenge in electrolysis production.

[0003] Traditional cathode plate hoisting methods often use fixed hoists, whose movement direction (i.e., the X-axis) is fixed during the hoisting process. Due to the limited space inside the electrolyzer and the close arrangement of cathode plates, how to accurately move the hook to the top of the target cathode plate's lifting lug and align it in both the Z-axis (vertical direction) and the Y-axis (horizontal direction, perpendicular to the X-axis) becomes a major challenge in actual operation.

[0004] Specifically, alignment in the Z-axis direction requires that hook 1 be able to move up and down to accurately align with the cathode plate's lifting lugs; while alignment in the Y-axis direction requires that hook 1 be able to be fine-tuned horizontally to accommodate the different positions of the cathode plate's lifting lugs, thereby achieving the purpose of partially lifting the cathode plate. However, this results in the need to align the cathode plate's lifting lugs in both the Z-axis and Y-axis directions when partially lifting the cathode plate, which is relatively inconvenient in actual operation.

[0005] Therefore, a hooking device for lifting cathode plates is needed to overcome the above problems. Utility Model Content

[0006] In order to solve the above problems, an embodiment of the present utility model provides a hooking device for lifting a cathode plate, which achieves the purpose of solving the problems raised in the background technology.

[0007] In order to achieve the above-mentioned purpose, the embodiment of the present utility model specifically adopts the following technical solutions: a hooking device for lifting cathode plates, comprising a running trolley, a frame is fixedly connected to the bottom of the running trolley, and a lifting device is provided inside the frame;

[0008] The sling comprises a positioning frame slidably arranged inside the frame, and a hooking assembly slidably arranged inside the positioning frame;

[0009] The hooking assembly includes a base frame slidably arranged inside the positioning frame and multiple hooks 1 rotatably arranged inside the base frame; there are multiple hooks 1, and the multiple hooks 1 are divided into two groups. The base frame is provided with an electric push rod 1 that drives one group of hooks 1 to rotate through a transmission assembly 1, and the base frame is also provided with an electric push rod 2 that drives the other group of hooks 1 to rotate through a transmission assembly 2.

[0010] As a further improvement of the above technical solution:

[0011] The transmission assembly includes a connecting piece 1 fixedly connected to one of the groups of hooks 1, a long connecting rod 1 hingedly arranged at one end of the plurality of connecting pieces 1, a hinge block 1 hingedly arranged on the base frame, and a short connecting rod 1 hingedly arranged between the hinge block 1 and the electric push rod 1;

[0012] The middle part of the hinge block 1 is hingedly arranged on the base frame, and the two ends of the hinge block 1 are hingedly connected to the long connecting rod 1 and the short connecting rod 1 respectively.

[0013] The second transmission assembly includes a second connecting piece fixedly connected to one group of the first hooks, a second long connecting rod hingedly arranged at one end of the plurality of second connecting pieces, a second hinge block hingedly arranged on the base frame, and a second short connecting rod hingedly arranged between the second hinge block and the second electric push rod;

[0014] One end of the hinge block 2 is hinged on the base frame, the other end of the hinge block 2 is hinged to the short connecting rod 2, and the middle part of the hinge block 2 is hinged to the long connecting rod 2.

[0015] The four corners of the positioning frame are each provided with a guide wheel group one, and the four guide wheel groups one are respectively slidably arranged at the four corners inside the frame.

[0016] A second guide wheel group is provided on both sides of the base frame, a guide plate is fixedly connected to the positioning frame, and the second guide wheel group is slidably provided on the guide plate.

[0017] The beneficial effects of the embodiments of the present utility model are:

[0018] During lifting, the lifting rope is released so that the positioning frame is located at the slot of the electrolytic cell. As the lifting rope is further released, the base frame moves downward along the positioning frame so that the lifting ear of one cathode plate of the hook is aligned in the Z-axis direction. Then, the electric push rod 1 is controlled to drive one group of hooks 1 to rotate and hook up part of the cathode plate. Then, the electric push rod 2 is controlled to drive the other group of hooks 1 to rotate and hook up another part of the cathode plate. That is, the multiple hooks 1 in this application are respectively aligned with the lifting ears of the cathode plate, that is, they are always aligned in the Y-axis direction. When hooking the cathode plate, it is only necessary to adjust the alignment in the Z-axis direction, which is convenient for actual operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0030] See also Figures 1 to 6 The embodiment of the utility model discloses a hooking device for lifting a cathode plate, comprising a running trolley 1, a frame 2 is fixedly connected to the bottom of the running trolley 1, and a sling is arranged inside the frame 2; the running trolley 1 is arranged on a walking beam, so that the running trolley 1 moves on the walking beam, that is, the X-axis direction is fixed, and the running trolley 1 can drive the frame 2 to move when moving, thereby achieving the purpose of driving the sling to move;

[0031] The sling includes a positioning frame 3 slidably arranged inside the frame 2 and a hook assembly 4 slidably arranged inside the positioning frame 3;

[0032] The hook assembly 4 includes a base frame 41 slidably disposed within the positioning frame 3, a plurality of hooks 42 rotatably disposed within the base frame 41, and a movable pulley set 47 mounted on the base frame 41; a plurality of hooks 42 are provided, and the plurality of hooks 42 are divided into two groups. The base frame 41 is provided with an electric push rod 44 that drives one group of hooks 42 to rotate via a transmission assembly 43. The base frame 41 is also provided with an electric push rod 46 that drives the other group of hooks 42 to rotate via a transmission assembly 45.

[0033] The movable pulley block 47 is connected to the running trolley 1 through a suspension rope. The running trolley 1 controls the lifting and lowering of the movable pulley block 47 by retracting and releasing the suspension rope, that is, adjusting the Z-axis direction.

[0034] During hoisting, the hoisting rope is released so that the positioning frame 3 is located at the slot of the electrolytic cell. As the hoisting rope is further released, the base frame 41 moves downward along the positioning frame 3, so that the lifting ears of the cathode plates of the hook 1 42 are aligned in the Z-axis direction. Then, the electric push rod 1 44 is controlled to drive one group of hooks 1 42 to rotate and hook up part of the cathode plates. Then, the electric push rod 2 46 is controlled to drive another group of hooks 1 42 to rotate and hook up another part of the cathode plates. That is, the multiple hooks 1 42 in this application are respectively aligned with the lifting ears of the cathode plates, that is, they are always aligned in the Y-axis direction. When hooking the cathode plate, it is only necessary to adjust the alignment in the Z-axis direction, which is convenient for actual operation.

[0035] As a further illustration of this application:

[0036] The transmission assembly 43 includes a connecting piece 431 fixedly connected to one set of hooks 42, a long connecting rod 432 hingedly provided at one end of the plurality of connecting pieces 431, a hinge block 433 hingedly provided on the base frame 41, and a short connecting rod 434 hingedly provided between the hinge block 433 and the electric push rod 44;

[0037] The middle part of the hinge block 433 is hinged on the base frame 41, and the two ends of the hinge block 433 are hinged to the long connecting rod 432 and the short connecting rod 434 respectively;

[0038] In actual use, when it is necessary to lift part of the cathode plate, the electric push rod 44 is started. After the electric push rod 44 moves, it drives the long link 432 to move through the short link 434 and the hinge block 433, which can drive one group of hooks 42 to rotate. After the hook 42 rotates 90 degrees, the hook 42 is hung on the lifting ear of the cathode plate, and now part of the cathode plate can be lifted;

[0039] The second transmission assembly 45 includes a second connecting piece 451 fixedly connected to one set of the first hooks 42, a second long connecting rod 452 hingedly provided at one end of the plurality of second connecting pieces 451, a second hinge block 453 hingedly provided on the base frame 41, and a second short connecting rod 454 hingedly provided between the second hinge block 453 and the second electric push rod 46;

[0040] One end of the second hinge block 453 is hingedly mounted on the base frame 41 , the other end of the second hinge block 453 is hingedly connected to the second short connecting rod 454 , and the middle portion of the second hinge block 453 is hingedly connected to the second long connecting rod 452 ;

[0041] When the remaining cathode plates need to be lifted, the electric push rod 2 46 is started. After the electric push rod 2 46 moves, it drives the long link 2 452 to move through the short link 2 454 and the hinge block 2 453, which can drive another set of hooks 1 42 to rotate, so that the hooks 1 42 are hung on the lifting ears of the cathode plates. At this time, the remaining cathode plates can be lifted.

[0042] As a further illustration of this application:

[0043] The four corners of the positioning frame 3 are each provided with a guide wheel group 5, and the four guide wheel groups 5 are respectively slidably set at the four corners inside the frame 2, so that the positioning frame 3 can move smoothly inside the frame 2, and at the same time maintain a stable relative relationship between the running trolley 1 and the positioning frame 3, that is, the running trolley 1 can only control the distance between it and the positioning frame 3 by retracting and extending the lifting rope, and when the positioning frame 3 is controlled to move by retracting and extending the lifting rope, the positioning frame 3 is restricted to move smoothly inside the frame 2 and will not swing.

[0044] As a further illustration of this application:

[0045] Guide wheel group 2 6 is provided on both sides of the base frame 41, and a guide plate 7 is fixedly connected to the positioning frame 3. The guide wheel group 2 6 is slidably set on the guide plate 7. Through the limiting effect of the guide plate 7 and the guide wheel group 2 6, the base frame 41 can slide smoothly on the positioning frame 3.
