[0039] Reference Figures 1 to 3 The lifting mechanism for grabbing lead electrolytic plates in the first embodiment of the present application is used for lifting and transporting anode and cathode plates in an electrolysis workshop. The lifting mechanism for grabbing lead electrolytic plates includes a hanger 100, multiple hook components 200 and a driving device 300.

[0040] The hook includes a transmission component 210 and a hook body 220, one end of the transmission component 210 is arranged on the hanger 100, and the other end of the transmission component 210 is rotatably connected to the hook body 220; the driving device 300 is arranged on the hanger 100, and the driving device 300 is connected to each hook, and the driving device 300 is used to drive the hook body 220 to rotate around the axis respectively, so that the direction of each hook body 220 can be adjusted.

[0041] It can be understood that the hook component 200 is designed as a rotatable and adjustable structure, and the driving device 300 drives the hook body 220 to rotate so that the direction of the hook can be in two positions perpendicular to the electrode plate or parallel to the electrode plate, or in between, thereby efficiently achieving the hooking or loosening of the electrode plate.

[0042] In some embodiments of the present application, the transmission component 210 includes a rotating portion 211 and a first connecting sleeve 212. The hook body 220 is provided with a second connecting sleeve. The first connecting sleeve 212 and the second connecting sleeve are detachably connected. The driving device 300 is used to drive the rotating portion 211 to rotate the hook body 220. It is understood that the hook is modified to a split upper and lower structure, with an upper transmission portion and a lower hook body 220, connected in the middle by a hook connecting sleeve via a pin. The split hook design makes it easier to replace any problems with the hook.

[0043] In some embodiments of the present application, the hook component 200 is divided into a cathode hook and an anode hook, and the driving device 300 includes a cathode electric push rod mechanism 310 and multiple cathode crank assemblies 320, an anode electric push rod mechanism 330 and multiple anode crank assemblies 340, the cathode electric push rod mechanism 310 is used to drive each cathode crank assembly 320 to move synchronously, and each cathode crank assembly 320 is connected to each cathode hook, and the anode electric push rod mechanism 330 is used to drive each anode crank assembly 340 to move synchronously, and each anode crank assembly 340 is connected to each anode hook, wherein the cathode electric push rod mechanism 310 and the anode electric push rod mechanism 330 move independently and have an electrical self-locking function.

[0044] It is understood that the anode and cathode plates are automatically hoisted between the lead electrolysis cell and the plate loading and unloading rack, enabling precise removal and loading of the anode and cathode plates. In some embodiments, the hanger 100 is constructed of a frame structure made of welded channel steel. The cathode and anode hooks are integrally machined from 321 stainless steel, offering high load capacity, resistance to deformation, and acid resistance. The hanger 100 is equipped with a cathode and anode hook rotation drive device 300, each powered by an electric push rod, to drive the hooks' rotation.

[0045] In some embodiments of the present application, the hook member 200 is provided with a limit switch connected to the drive device 300 to control the rotation angle, and the hook body 220 can rotate between 0 and 90 degrees relative to the transmission member 210. It is understood that the limit switch provided on the sling controls the rotation angle of the hook, and the direction of the hook can be set to either perpendicular to the plate or parallel to the plate, thereby achieving hooking or releasing the plate.

[0046] In some embodiments, the cathode and anode plate push rod mechanisms are driven by electric push rods to drive the cathode and anode hooks to reciprocate between 0 and 90 degrees, and ensure that the cathode and anode hooks can be accurately positioned at the positions of 0 to 90 degrees under electrical control; the cathode and anode hooks can move simultaneously or separately; when the cathode plate or the anode plate is placed separately, electrical interlocking is used to ensure that the anode hook (cathode hook) will not move while the cathode hook (anode hook) rotates; since the sling adopts the form of one push rod driving multiple cranks to rotate, the synchronous performance of the hook rotation is well guaranteed.

[0047] In some embodiments, the hook mouth is beveled at 80 degrees, and the hook head is processed with a rib. During the plate removal and lifting process, the plate can be guided into the hook mouth along the inclined surface of the rib and pressed against the hook under the action of gravity, ensuring that the pole distance is always 110 mm. In addition, the rib can also prevent the plate from being unhooked during the operation of the large and small vehicles.

[0048] In some embodiments of the present application, the cathode hook is located inside the anode hook, and the cathode hook and the anode hook are arranged opposite each other. It is understood that by changing the position of the cathode and anode plate hooks, so that the cathode plate hook is inside and the anode plate hook is outside, and the hook heads of the two hooks are arranged opposite each other, the anode and cathode plate hooks rotate in opposite directions. When lifting the anode and cathode plates simultaneously, some deformation of the hooks does not affect the normal use of the lifting device, and the hooks have a large deformation margin.

[0049] Reference Figures 1 to 3 The transfer equipment of the second embodiment of the present application can be a multifunctional insulated automatic crane, which can be installed on the track beam above the electrolysis workshop. The transfer equipment includes the lifting mechanism for grabbing lead electrolytic plates of the first embodiment of the present application. The multifunctional insulated automatic crane is an ideal and efficient continuous transfer equipment for electrolysis workshop plates. Compared with other transportation equipment (such as locomotives), it has the advantages of long transportation distance, large transportation capacity, and continuous transportation. It is also reliable in operation and easy to implement automation and centralized control.

[0050] In some embodiments, the multifunctional insulated automatic crane features laser ranging for rapid and coarse positioning. A fixed frame with anti-sway function facilitates high-speed transportation. A positioning guide frame can be easily extended and retracted for fast and precise positioning.

[0051] In some embodiments of the present application, the transfer equipment includes a main structure 400, a trolley mechanism 500 and a trolley mechanism 600. The trolley mechanism 500 can be slidably set on the main structure 400. The trolley mechanism 600 includes a lifting mechanism, a running mechanism and a frame. The running mechanism is set on the frame so that the trolley mechanism 600 can be movably set on the trolley mechanism 500. The lifting mechanism is set on the frame and is connected to the hoisting mechanism for grabbing lead electrolytic plates so that the hoisting mechanism for grabbing lead electrolytic plates can be raised and lowered.

[0052] It is understandable that the crane bridge is a box-shaped double-beam two-track structure, consisting of a main beam, an end beam, etc. The trolley running mechanism consists of a three-in-one motor reducer, a main and passive wheel set, a buffer, etc. The trolley is arranged in an upper and lower layer, with the lower layer being the left and right walking end beams, and the upper layer being the trolley frame assembly weldment. After the trolley frame assembly is welded, the entire body is annealed to eliminate stress, and then the entire body is processed to ensure processing accuracy. The trolley frame assembly weldment is mainly welded by a combination of steel sections and box beams, and the main material is Q355B. The upper surface of the trolley frame is equipped with a lifting mechanism and a running mechanism. The bottom of the trolley frame is connected to the fixed guide frame of the sling, and the two sides of the trolley frame are connected to the trolley end beam walking trolley, and the positioning accuracy is improved by the end beam positioning cone, and insulation is provided at the same time. The lifting mechanism consists of a variable frequency motor, coupling, drive shaft, disc brake, reducer, drum coupling, drum group, pulley, wire rope, encoder and various limit safety devices. The speed adjustment adopts variable frequency closed-loop speed control (equipped with an incremental encoder for speed feedback), and the lifting stroke is controlled by PLC (an absolute encoder is provided at the end of the drum for height feedback, the encoder accuracy is higher than 0.1mm and a switch signal input is also provided).

[0053] In some embodiments, the main beam is a skewed box beam with a trolley track welded to the main beam. The end beams are welded steel plate box beams, integrally welded to the main beam, and articulated to the middle end beam via an axis. In some embodiments, buffers are installed at both ends of the end beams, and trolley travel switches are mounted on the end beams, providing deceleration and parking functions.

[0054] In some embodiments of the present application, the transfer equipment includes a guide movable frame 700, which includes a guide frame body, a flexible shock-absorbing device and two positioning devices. The guide movable frame 700 is connected to the trolley mechanism 600, and each positioning device is respectively installed at the head and tail ends of the guide frame body. The flexible shock-absorbing device is arranged at the connection between the guide movable frame 700 and the trolley mechanism 600.

[0055] As you can understand, the spreader guide frame is welded from steel sections. Its upper portion is connected to the bottom of the trolley frame, with flexible shock absorbers installed at the joint. Guides are installed at the four corners of the lower frame to prevent the movable frame from swaying. The sides of the frame house the liquid collection pan drive and guide wheels. The liquid collection pan consists of a pan body and a bracket. The pan body is constructed of 316L stainless steel and is mounted on the lower bracket. Sprockets and guide rails are mounted on either side of the bracket. A reduction motor mounted on the frame drives the sprockets, which in turn drive the chain to enable horizontal movement of the liquid collection pan.

[0056] In some embodiments, the positioning device consists of a positioning hole and a positioning plate, which are installed at the head and tail ends of the guide frame. The positioning hole and the positioning plate are installed diagonally, and the holes correspond to the positioning cones on the electrolytic cell surface and the unit respectively.

[0057] In some embodiments of the present application, the transfer device includes an anti-sway fixed frame 800, which includes an anti-sway frame body and an anti-sway comb. The anti-sway frame body is disposed between the movable guide frame 700 and the trolley mechanism 600, and the anti-sway comb is disposed on the anti-sway frame body and is used to limit the swing of the electrode plate. It will be understood that the anti-sway frame body and the anti-sway comb function to prevent the movable guide frame 700 and the hanger 100 from swinging during lifting and lowering operations, while also providing support for the liquid receiving tray.

[0058] In some embodiments of the present application, the unloaded crane is powered on and activated. The crane's large and small carriages simultaneously automatically or manually move to the top of a designated electrolytic cell or plate storage rack. The liquid receiving tray on the anti-sway fixed frame is then fully opened by the reduction motor. The electric push rod on the hanger 100 then retracts the anti-fall latch, and the drum reduction motor on the trolley is activated, causing the crane's large hook to move downward. The hanger 100 and the sling attached to the hook also move downward. Simultaneously, the guide movable frame, supported by the support blocks on the hanger 100, also moves downward with the hanger 100 and sling under its own weight. When the crane reaches a certain height, the positioning cones on the electrolytic cell or plate storage rack begin to enter the positioning holes on the positioning support plate below the guide movable frame, guiding the frame until it is completely placed on the electrolytic cell or plate storage rack. As the hanger 100 and sling continue to descend, the contoured frame on the hanger 100 causes the plate anti-sway comb on the guide movable frame to open to prevent interference between subsequent hangers 100 and the anti-sway comb. The hanger 100 and the sling continue to descend until the cathode and anode hook heads on the sling enter the gap between the adjacent plates. Then the cathode hook and the anode hook are respectively rotated 90 degrees by a set of electric push rods to reach the lifting station. After that, the drum reduction motor on the trolley rotates in the opposite direction so that the large crane hook starts to move upward with the hanger 100 and the sling. Subsequently, when the cathode and anode hooks respectively hook the cathode and anode plates, the cathode and anode plates are also lifted upward together with the hanger 100 and the sling. When it is lifted to a certain height, the anti-swing comb on the hanger 100 is lowered along the contour frame under the action of gravity to limit the swing of the plates. Then, starting from the moment the support block on the hanger 100 contacts the guide movable frame, the guide movable frame is also lifted upward together with the hanger 100 and the sling. When the guide frame, hanger 100, sling, and cathode and anode plates are fully inside the anti-sway fixed frame and reach the upper limit, the electric push rod on the hanger 100 pushes out the anti-fall latch, and the liquid collection tray on the anti-sway fixed frame is completely closed by the reduction motor. The large and small carriages then proceed to the next electrolytic cell or plate storage rack as instructed. This cycle repeats, the only difference being whether the cells are being unloaded or loaded.

[0059] Loading the tank: Take a whole tank of anode and cathode plates from the fixed plate-taking position of the lead anode and cathode automatic plate arrangement unit or the anode and cathode plate storage rack, and lift them into the electrolytic tank.

[0060] Out of the tank: The crane takes out a whole tank of plates from the electrolytic cell, puts the residual anode plates on the fixed plate placing chain of the residual anode washing unit, and then lifts the cathode plates to the lead precipitation washing and rod extraction unit, and places the cathode on the fixed plate placing chain of the unit (the unit chain stops running when placing the plates).

[0061] The crane is equipped with an electric hoist, which is responsible for removing and lifting the plates that have fallen into the electrolytic cell, lifting simple equipment on the cell surface, lifting components during the maintenance of the residual anode washing unit, or removing and lifting the plates that have fallen from the residual anode washing machine and cathode washing machine.

[0062] The crane is designed as a high-strength insulated crane specifically for metallurgy, providing a reliable and professional system to ensure a smooth production process. The fully automatic control system, equipped with a safety alarm, ensures the safety of equipment and personnel during production operations. In manual operation mode, the remote control or buttons on the operating box enable inching of various mechanisms, including gantry and trolley travel, main hoist / lower with two or three speeds (high, medium, and low), liquid tray switch, and male / female hook rotation. In automatic mode on the remote control or operating box, tank unloading and loading can be automatically performed according to on-site parameter settings, eliminating the need for human intervention during the transfer process.

[0063] Reference Figures 1 to 3 The production line of the third embodiment of the present application can be an aluminum electrolysis production line, and the production line includes the transfer equipment of the second embodiment of the present application. Since the transfer equipment has the lifting mechanism for grabbing lead electrolysis plates of the first embodiment of the present application, the transfer equipment has higher safety performance and faster lifting and transfer efficiency, so that the production line with this transfer equipment has higher production efficiency and higher production quality.

[0064] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present application.
