Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of electrolytic aluminum equipment, specifically to an anti-fall-off device for multi-functional overhead crane operation in electrolytic aluminum. Background Technology
[0002] In electrolytic aluminum production, the multi-functional overhead crane is the core equipment for replacing anode carbon blocks. Its standard operating procedure is as follows: First, the anode lifting mechanism drives the anode guide rod clamp to hold the anode guide rod on top of the anode carbon block. Then, the screw head lifting mechanism drives the screw head mechanism to descend, so that it acts on the bidirectional screw on the small box clamp that fixes the anode guide rod. During this process, in order to prevent the small box clamp from loosening, the worker needs to control the hook on the screw head mechanism to hook it onto the small box clamp before the subsequent replacement operation can be completed.
[0003] However, during the replacement of anode carbon blocks, the anode guide rod clamp may experience insufficient or unstable clamping force due to equipment vibration, misalignment, or wear of the clamp itself. This poses a risk of the anode guide rod falling off, which could not only interrupt the production process and reduce efficiency but also potentially cause serious equipment collision accidents. Secondly, in the process of preventing the small box clamp from falling off, workers need to operate the hook to hold the small box clamp at close range in a harsh environment with high temperature and high dust. Exposure to high temperature can easily lead to health damage and poses safety hazards such as burns and mechanical injuries. Therefore, there are still shortcomings and deficiencies in the existing technology. Utility Model Content

[0014] The present invention will now be further described with reference to the accompanying drawings.
[0015] like Figure 1-4As shown, this utility model provides an anti-fall-off device for a multi-functional overhead crane operation in aluminum electrolysis, including an anode lifting rod 1. A screw-head lifting mechanism 2 is hinged to one side of the anode lifting rod 1. An installation block 3 is fixedly connected to the bottom end of the anode lifting rod 1. A receiving cavity 4 is opened at the bottom end of the installation block 3. Through holes 5 are opened on both sides of the receiving cavity 4. A first hydraulic cylinder 6 corresponding to the position of the through hole 5 is installed on the outside of the installation block 3. When the extension end of the first hydraulic cylinder 6 is extended, it can penetrate through the through hole 5. A screw-head mechanism 7 is hinged to the bottom end of the screw-head lifting mechanism 2. An installation plate 8 is fixedly connected to the side of the screw-head mechanism 7 away from the installation block 3. A vertically arranged fixing rod 9 is fixedly connected to the bottom surface of the installation plate 8. A swing arm 10 is hinged to the bottom end of the fixing rod 9. A second hydraulic cylinder 11 is hinged between the end of the swing arm 10 away from the screw-head mechanism 7 and the installation plate 8. A connecting plate 12 is fixedly connected to the end of the swing arm 10 near the screw-head mechanism 7. A support plate 13 is fixedly connected to the end of the connecting plate 12 near the screw-head mechanism 7.
[0016] Specifically, the top of the anode guide rod 19 has a through hole 20. In use, firstly, the anode lifting rod 1 is lowered, causing the receiving cavity 4 of the mounting block 3 to fit into the top of the anode guide rod 19 until the through hole 20 of the anode guide rod 19 aligns with the through hole 5. Next, the first hydraulic cylinder 6 is activated, and its telescopic end extends, passing through the through hole 5 and the through hole 20 in sequence to form a mechanical lock, thus preventing the anode guide rod 19 from falling off. Then, the screw-head lifting mechanism 2 is lowered, causing the screw-head mechanism 7 to... The sleeve is inserted into the bidirectional screw of the small box clamp 21. At the same time, the second hydraulic cylinder 11 is activated. The telescopic end of the second hydraulic cylinder extends and pushes the swing arm 10 to rotate around the fixed rod 9. The swing arm 10 drives the support plate 13 to rotate to the bottom of the small box clamp 21 through the connecting plate 12, so as to support the small box clamp 21. Combined with the fixing of the bidirectional screw by the screwing mechanism 7, a multi-point fixing of the small box clamp 21 is formed, which can prevent the small box clamp 21 from falling off during the rising or falling process. Finally, the anode carbon block can be replaced.
[0017] In some embodiments, the support plate 13 includes a support portion 131, and both ends of the support portion 131 are fixedly connected to inclined limiting portions 132. Specifically, the support portion 131 is used to support the small box clamp 21, and the limiting portions 132 limit both ends of the small box clamp 21, thereby preventing the small box clamp 21 from shaking or falling off.
[0018] In some embodiments, the included angle between the limiting part 132 and the supporting part 131 is 120°-150°, which can effectively limit the movement and facilitate the entry and exit of the small box clamp 21.
[0019] In some embodiments, the support plate 13 is provided with a clearance hole 14, which is used to avoid the bidirectional screw of the small box clamp 21 and prevent interference.
[0020] In some embodiments, a guide wheel 15 is mounted on the side of the screwing mechanism 7 near the mounting block 3, and a guide plate 16 adapted to the guide wheel 15 is fixedly connected to the mounting block 3. Specifically, the guide plate 16 is used to guide the guide wheel 15 to fit against the anode guide rod 19 during descent, and the guide wheel 15 can limit the position of the screwing mechanism 7 to ensure that the sleeve of the screwing mechanism 7 is aligned with the bidirectional screw.
[0021] In some embodiments, both sides of the screwing mechanism 7 are hinged with limiting plates 17, and the bottom end of the limiting plates 17 is provided with an inverted U-shaped limiting groove 18. Specifically, when the screwing mechanism 7 descends, the limiting groove 18 engages with the hanging shaft of the small box clamp 21, thereby positioning the small box clamp 21, preventing the small box clamp 21 from rotating with the bidirectional screw, and improving the fixing effect of the anti-detachment device on the small box clamp 21.
[0022] The above embodiments can be combined with each other.
[0023] The above embodiments are not intended to limit the shape, material, structure, etc. of this utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
