Description

Technical Field

[0001] This utility model belongs to the field of aluminum electrolysis technology, specifically relating to a quick disassembly and assembly device for aluminum electrolysis short-circuit busbars and a matching mounting hole alignment and calibration tool kit. Background Technology

[0002] When the aluminum electrolysis workshop requires phased production or emergency power outages, the short-circuit busbars on the series busbars need to be installed and dismantled. Due to the powerful current in electrolysis, the installation and dismantling of the short-circuit busbars require power outages of the entire electrolysis series. Currently, dismantling the short-circuit busbars involves five busbars under each corridor, with 5-6 people working on each busbar simultaneously. The entire series of operations takes more than 40 minutes. The limited work area and the large number of people gathered in a short period pose significant safety risks.

[0003] The current disassembly and assembly process requires drilling a hole in the corresponding location on the concrete platform of the aluminum electrolysis workshop corridor, suspending a load-bearing iron lifting ring, attaching a manual hoist, and using a lifting device to suspend the flexible busbar, relying on the manual hoist to adjust the height. However, the lifting device cannot accurately and stably adjust the alignment accuracy of the alignment holes of the rigid and flexible busbars during operation, and there is a risk of falling. To loosen and remove the fastening bolts, a tapered insulating rod one size smaller than the installation hole is inserted for temporary positioning. However, inserting and removing the tapered insulating rod during disassembly and assembly is very difficult and requires considerable effort. After removing the installation screws of the flexible busbar, the manual hoist used for disassembly and assembly must also be removed. At this time, multiple layers of insulation must be laid under the flexible busbar for load-bearing. If the ground is uneven or the stress is uneven, the busbar may tilt or the installation hole may deviate due to its own weight and uneven stress.

[0004] On the other hand, patent application number CN201711490271X also discloses an aluminum electrolytic short-circuit busbar disassembly and assembly mechanism, including a lifting trolley with a rectangular frame structure, which can quickly, efficiently, safely and reliably install and disassemble the short-circuit busbar, and is very convenient to operate. However, the limited space under the corridor is not conducive to the intervention of large equipment, and the safety risks increase when multiple people participate in the operation at the same time, which is extremely detrimental to production operations.

[0005] Therefore, this application provides a mechanism for quickly dismantling the short-circuited busbar under the aluminum electrolysis corridor, so as to realize a fast dismantling mechanical device that is stable, reliable and quick, which can improve work efficiency and reduce operational risks.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0032] See attached document Figure 1-3 A quick disassembly and assembly device for aluminum electrolytic short-circuit busbars, comprising:

[0033] The main frame 1 is made of stainless steel I-beams, with the material selection taking into account the need to eliminate the influence of magnetic fields. A crossbeam 5 is provided between the two side plates of the main frame 1.

[0034] The manual lead screw advance / retreat mechanism includes a lead screw 2, a wheel-type crank handle 3, a slide 4, and a fixed seat; the lead screw 2 passes through the front end of the main frame 1; the wheel-type crank handle 3 is fixed to the end of the lead screw 2 located outside the main frame 1; the slide 4 is threadedly engaged with the lead screw 2; the fixed seat is rotatably connected to the end of the lead screw 2 located inside the main frame 1, and its bottom is fixed to the crossbeam 5;

[0035] The fixed platform 6 is fixed to the two side plates of the main frame 1 by two support plates at its bottom; the fixed platform 6 is located near the rear end of the main frame 1.

[0036] The mobile platform 7 has independent worm gear lifters 8 arranged at its four corners. A load-bearing plate 11 is placed above the four worm gear lifters 8, which can accommodate the flexible connection busbar 17.

[0037] In order to adjust the precise alignment of the mounting holes when quickly disassembling and assembling the short-circuit busbar, the load-bearing plate 11 needs to be horizontally adjusted twice. This is achieved by adjusting the worm gear lifters 8 at different positions to make fine adjustments to the horizontal level of the load-bearing platform, so as to achieve precise alignment of the mounting holes.

[0038] The bottom of the mobile platform 7 is provided with pulley groups 9 on both sides, which cooperate with the side plates of the main frame 1. The pulley group 9 includes an n-shaped guard frame, load-bearing wheels and directional wheels. The top of the n-shaped guard frame is welded to the bottom of the mobile platform 7. The load-bearing wheels are set between the two side plates of the n-shaped guard frame and are located above the side plates of the main frame 1. Two directional wheels are symmetrically arranged below the load-bearing wheels and are fixed to the two side plates of the n-shaped guard frame respectively.

[0039] In this embodiment, an inverted T-shaped connecting plate 10 is provided at the bottom center of the mobile platform 7. The bottom of the connecting plate 10 is welded and fixed to the top of the slide block 4 to ensure that the left and right sides of the mobile platform 7 move synchronously. The mobile platform 7 is also provided with a fastener 13, as shown in the attached figure. Figure 4 This is used to prevent displacement of the flexible busbar 17 during platform disassembly and horizontal adjustment, ensuring precise alignment of the mounting holes. The fastener 13 includes a limiting rod, a threaded rod, a first fastening plate, and a second fastening plate. Two limiting rods are arranged in parallel and welded to one limiting plate. The threaded rod is located between the two limiting rods, with one end rotatably connected to the first fastening plate. The first fastening plate is fixed to the two limiting rods, and the second fastening plate is threadedly engaged with the threaded rod.

[0040] The flexible busbar 17 is moved via a mobile platform 7 and a manual screw advance / retreat mechanism. Operators can manually rotate the wheeled crank 3 to adjust the advance / retreat mode of the mobile platform 7 clockwise and counterclockwise. The load-bearing surface of the mobile platform 7 is made of stainless steel for anti-magnetic protection. At the contact surface between the load-bearing plate 11 above the platform and the flexible busbar 17, a custom-made epoxy insulation board is required as the first line of insulation.

[0041] Since the load-bearing capacity of the mobile platform 7 is >400KG, this embodiment uses four sets of horizontally opposed I-beam special pulley blocks 9 to achieve stable and efficient movement of the mobile platform 7.

[0042] In order to make precise alignment of the mounting holes when quickly disassembling and assembling the short-circuit busbar, the mobile platform 7 needs to be adjusted horizontally a second time. This is achieved by using independent worm gear lifters 8 arranged at the four corners and adjusting the worm gear lifters 8 at different positions to make fine adjustments to the horizontal level of the mobile platform 7, thereby achieving precise alignment of the mounting holes.

[0043] On the other hand, the rigid connection busbar 18 is installed on the fixed platform 6. The contact surface between the fixed platform 6 and the rigid connection busbar 18 needs to be customized with epoxy insulation board to achieve the first insulation measure.

[0044] In this embodiment, four support feet 12 are installed below the main frame 1 of the entire mechanical device. The support feet 12 are made of high-strength universal feet, which can adjust the horizontal alignment of the rigid and flexible busbars 17. The support frame of the universal feet is made of stainless steel, and a custom-made epoxy insulation board is installed at its bottom and fixed to the ground by countersunk head method, which can ensure the stability of the entire quick assembly and disassembly mechanical device and achieve a second insulation measure.

[0045] See attached document Figure 5 This application also provides a mounting hole alignment and calibration tool kit for use with a quick disassembly and assembly device for aluminum electrolytic short-circuit busbars, including a stainless steel bracket 14, a split hydraulic pusher 15, and a conical insulating rod 16. The stainless steel bracket 14 is n-shaped and made of high-strength stainless steel, serving to prevent magnetism and reduce tool weight, while ensuring the strength and aesthetics of the tool kit. The stainless steel bracket 14 has protective plates on both sides, one of which contacts the rigid connection busbar 18 and is protected by an epoxy insulation plate to prevent contact between the tool kit and the conductive busbar. The split hydraulic pusher 15 is mounted on one side of the protective plate; its small size and easy disassembly and assembly, combined with its high pushing pressure, allow for quick and effective pushing of the conical insulating rod 16 into the mounting hole, achieving accurate alignment of the mounting hole. An epoxy insulation plate is installed at the contact point between the end of the split hydraulic pusher and the flexible connection busbar 17 to prevent contact with the conductive busbar. The head of the tapered insulating rod 16 passes through the flexible busbar 17 and enters the interior of the rigid busbar 18, while its tail faces the telescopic end of the split hydraulic pusher 15. Its main function is to provide embedded expansion and calibrate the hole positions. Since the tapered insulating rod 16 is in direct contact with the conductive busbar, it must be made of high-strength epoxy insulation material and is custom-machined on a lathe according to the size of the installation holes on site.

[0046] In actual installation, the limited space under the corridor in the aluminum electrolysis workshop hinders the access of large equipment. With multiple people working simultaneously, safety risks increase, which is extremely detrimental to production operations. The aluminum electrolysis short-circuit busbar quick-disassembly and assembly device of this application, used in conjunction with fasteners and a mounting hole alignment tool kit, enables rapid and precise alignment of the mounting holes. By rotating the wheel-type crank handle 3, the operator can move the sliding block 4, moving the mobile platform 7 away from or closer to the fixed platform 6, to facilitate the disassembly and assembly of the flexible busbar 17 and the rigid busbar 18. This improves work efficiency and reduces operational risks, making it highly practical and showing promising market application prospects.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
