Description

Technical Field

[0001] The present invention relates to the field of electrolytic aluminum, and particularly to a hoisting structure for the anode of an electrolytic cell. Background Art

[0002] Electrolytic aluminum enterprises use electrolytic cell devices for electrolyzing aluminum. The electrolytic cell is equipped with an anode. During the actual production process, a crane is needed to hoist the anode for transfer to meet the production and maintenance requirements of the electrolytic cell device.

[0003] Currently, for the hook device equipped with the overhead crane in electrolytic aluminum enterprises, during the process of hoisting and disengaging the anode, manual locking and manual unlocking are required, resulting in a relatively high manual labor intensity. Moreover, due to the long length of the anode, there is also a risk during locking and unlocking.

[0004] Therefore, how to design a hook device for hoisting the anode of an electrolytic cell and capable of automatic locking and unlocking is an urgent problem to be solved by those skilled in the art. Summary of the Invention

The structure is simple and the processing cost is low. It can automatically lock and unlock during the process of hoisting the anode, greatly reducing the manual labor intensity and ensuring the safety of the hoisting and transfer of the anode.

[0006] The technical solution of the present invention is: an electrolytic cell anode hoisting structure, including a hoisting mechanism and a control mechanism. The hoisting mechanism includes a lifting ring, a first articulated arm, a second articulated arm, and a sleeve. There are two relief holes on the side wall of the sleeve, and the two relief holes evenly divide the 360° circumference. The first articulated arm and the second articulated arm are both composed of an upper articulated section and a lower articulated section hinged together. The first articulated arm and the second articulated arm are distributed on both sides of the sleeve. The upper articulated sections of the first articulated arm and the second articulated arm are respectively hinged to the lifting ring. The lower articulated sections of the first articulated arm and the second articulated arm are respectively hinged to the sleeve and are located below the corresponding relief holes. An anode hook is fixedly arranged on each lower articulated section. Each anode hook is vertically distributed with respect to the lower articulated section and corresponds to the relief hole. The control mechanism includes a mounting cylinder, an upper guide cylinder, a lower guide cylinder, a movable clamp, and a piston rod. The upper guide cylinder is arranged at the upper part of the mounting cylinder. Four first one-way teeth are provided on the lower circumference of the upper guide cylinder, and the four first one-way teeth evenly divide the 360° circumference. Two guide opening grooves are provided on the side wall of the upper guide cylinder. These two guide opening grooves extend in the vertical direction and evenly divide the 360° circumference. The notch of the guide opening groove is located between two adjacent first one-way teeth. The lower guide cylinder is arranged at the lower part of the mounting cylinder. Four second one-way teeth are provided on the upper circumference of the lower guide cylinder, and the four second one-way teeth evenly divide the 360° circumference. The orientation of each second one-way tooth is opposite to that of the first one-way tooth and is arranged in a staggered manner. The piston rod is slidably fitted in the inner hole of the upper guide cylinder. The movable clamp includes a ferrule and two arms provided on the ferrule. These two arms extend radially outwards and evenly divide the 360° circumference. The movable clamp is sleeved on the piston rod through the ferrule and is located between the upper guide cylinder and the lower guide cylinder. The mounting cylinder of the control mechanism is fixed outside the sleeve of the hoisting mechanism. The upper end of the piston rod extends upwards and is fixedly connected to the lifting ring, combining to form an electrolytic cell anode hoisting structure.

[0011] Adopting the above technical solution has the following beneficial effects:

[0012] 1. The electrolytic cell anode hoisting structure includes a hoisting mechanism and a control mechanism. Among them, the hoisting mechanism is used to hoist or release the electrolytic cell anode, and the control mechanism is used to control the working state of the hoisting mechanism. The hoisting mechanism includes a lifting ring, a first articulated arm, a second articulated arm, and a sleeve. Two relief holes are provided on the side wall of the sleeve, and the two relief holes evenly divide the 360° circumference. The first articulated arm and the second articulated arm are each composed of an upper articulated section and a lower articulated section hinged together. The first articulated arm and the second articulated arm are distributed on both sides of the sleeve. The upper articulated sections of the first articulated arm and the second articulated arm are respectively hinged to the lifting ring, and the lower articulated sections of the first articulated arm and the second articulated arm are respectively hinged to the sleeve and are located below the corresponding relief holes. An anode hook is fixedly provided on each lower articulated section. Each anode hook is vertically distributed with respect to the lower articulated section and corresponds to the relief hole. When the height difference between the lifting ring and the sleeve becomes smaller, the angle between the upper articulated section and the lower articulated section of each articulated arm becomes smaller, causing the corresponding anode hook to rotate out of the relief hole to make way for the anode. When the height difference between the lifting ring and the sleeve becomes larger, the angle between the upper articulated section and the lower articulated section of each articulated arm becomes larger, causing the corresponding anode hook to rotate into the relief hole and be inserted into the hoisting hole of the electrolytic cell anode to position the electrolytic cell anode in the sleeve. The control mechanism includes an installation cylinder, an upper guide cylinder, a lower guide cylinder, a movable clamp, and a piston rod. The upper guide cylinder is provided at the upper part of the installation cylinder. Four first one-way teeth are provided on the lower circumference of the upper guide cylinder, and the four first one-way teeth evenly divide the 360° circumference. Two guide opening grooves are provided on the side wall of the upper guide cylinder. These two guide opening grooves extend in the vertical direction and evenly divide the 360° circumference. The notch of the guide opening groove is located between two adjacent first one-way teeth. The lower guide cylinder is provided at the lower part of the installation cylinder. Four second one-way teeth are provided on the upper circumference of the lower guide cylinder, and the four second one-way teeth evenly divide the 360° circumference. The deflection direction of each second one-way tooth is the same as that of the first one-way tooth and is arranged in a staggered manner. The piston rod is slidably fitted in the inner hole of the upper guide cylinder. The movable clamp includes a collar and two arms provided on the collar. These two arms extend radially outward and evenly divide the 360° circumference. The movable clamp is sleeved on the piston rod through the collar and is located between the upper guide cylinder and the lower guide cylinder. The movable clamp can be driven by the piston rod to move upward or downward. During the upward movement, the arm of the movable clamp cooperates with the corresponding first one-way tooth to make the movable clamp rotate 90° around the piston rod. During the downward movement, the arm of the movable clamp cooperates with the corresponding second one-way tooth to make the movable clamp rotate 90° in the reverse direction around the piston rod.The mounting cylinder of the control mechanism is fixed outside the sleeve of the hoisting mechanism. The upper end of the piston rod extends upward and is fixedly connected to the lifting ring, forming an electrolytic cell anode hoisting structure in combination. In this hoisting structure, the lifting ring is suspended on the overhead crane. In this state, the movable clamp is positioned by the first one-way tooth adjacent to the guiding opening groove of the upper guiding cylinder, causing the lifting ring to move away from the sleeve. The anode hook is located outside the sleeve. Manually control the overhead crane to transfer the hoisting structure above the electrolytic cell anode and then lower it, so that the hoisting end (upper end) of the electrolytic cell anode is inserted into the sleeve. The lifting ring, piston rod, and movable clamp move downward under the action of gravity. During the movement, the support arm of the movable clamp cooperates with the second one-way tooth, is driven by the second one-way tooth to rotate 90°, and is positioned by the second one-way tooth, restricting the movement distance of the lifting ring, piston rod, and movable clamp (in this state, the height difference between the lifting ring and the sleeve is the smallest and it is in the open state). Then manually control the overhead crane to lift, driving the lifting ring, piston rod, and movable clamp to move upward, and making the support arm of the movable clamp cooperate with the guiding opening groove, and finally being positioned by the guiding opening groove (in this state, the height difference between the lifting ring and the sleeve is the largest and it is in the locked state, and the anode hook locks the electrolytic cell anode). After the electrolytic cell anode can be hoisted to the designated position by the overhead crane, manually control the overhead crane to lower it. After the electrolytic cell anode is stably supported, the lifting ring, piston rod, and movable clamp continue to move downward under the action of gravity to release the lock on the electrolytic cell anode. During the movement, the support arm of the movable clamp cooperates with the second one-way tooth, is driven by the second one-way tooth to rotate 90°, and is positioned by the second one-way tooth. Then manually control the overhead crane to lift, driving the lifting ring, piston rod, and movable clamp to move upward, and finally being positioned by the first one-way tooth and being in the open state. The hoisting structure is separated from the electrolytic cell anode, achieving the purpose of hoisting and transferring. The entire hoisting and transferring process realizes automatic locking and unlocking, which can greatly reduce the manual labor intensity and has high safety.

[0013] 2. The lower end opening of the sleeve is in a flared shape, enabling the hoisting end of the electrolytic cell anode to be quickly inserted into the sleeve, improving the hoisting efficiency.

[0014] 3. The upper end of the mounting cylinder is provided with a first threaded hole, and the lower end is provided with a second threaded hole. The upper guiding cylinder is arranged on the upper part of the mounting cylinder and is positioned by being threadedly engaged with the first threaded hole through a first bolt. The lower guiding cylinder is arranged on the lower part of the mounting cylinder and is positioned by being threadedly engaged with the second threaded hole through a second bolt, facilitating the assembly and maintenance of the hoisting structure. A limiting ring platform is arranged at the upper end of the mounting cylinder, and a limiting step is provided on the circumference of the upper guiding cylinder. The upper guiding cylinder is axially positioned by the cooperation of the limiting step and the limiting ring platform of the mounting cylinder, improving the load-bearing capacity of the hoisting structure and ensuring the safety of the hoisting process.

In this state, the height difference between the lifting ring and the sleeve is the largest, and it is in a locked state. The anode hook locks the electrolytic cell anode. After the electrolytic cell anode is lifted to the specified position by the crane, the crane is manually controlled to fall, so that the electrolytic cell anode support is stable. The lifting ring, piston rod, and movable clamp continue to move downward under the action of gravity, and the anode hook rotates out of the clearance hole and the sleeve to release the lock on the electrolytic cell anode.
