Description

Technical Field

[0001] This utility model relates to an indicator device for the lowering position of the busbar frame of an aluminum electrolytic cell, belonging to the technical field of aluminum electrolytic cell busbars. Background Technology

[0002] In aluminum electrolysis production, a busbar is a type of conductor that transmits current from the power source to the electrolytic cell. It is generally made of copper. The function of the busbar is to transmit current, improve electrolysis efficiency and product quality. The main busbar is the main transmission channel for current in the electrolytic cell. It is usually laid underground in the furnace hall to send current from the substation to the aluminum electrolytic cell. Branch busbars are branches pulled out from the main busbar and are used to connect carbon blocks or steel frames and other structures on the electrolytic cell.

[0003] The existing aluminum electrolytic cell busbar frame requires manual measurement of its levelness after installation, as it cannot provide quick indication of the horizontal position. This necessitates repeated operations, which is time-consuming and reduces the installation efficiency of the aluminum electrolytic cell busbar frame. Furthermore, during the frame installation and adjustment process, the height is usually adjusted by adjusting the nuts, but these nuts are prone to loosening, and multiple nuts need to be adjusted, which affects the stability and convenience of the frame installation and makes it difficult to quickly fix the aluminum electrolytic cell busbar. Utility Model Content

[0004] The purpose of this utility model is to provide an indicator device for the lowering position of the busbar frame of an aluminum electrolysis cell, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A device for indicating the lowering position of a busbar frame in an aluminum electrolysis cell includes a top frame, a support frame, and a mounting plate. The support frame is fixedly connected to the lower end of the top frame. A pressure plate is located at the middle of the lower end of the top frame. A power-conducting frame is fixedly connected to the middle of the upper end of the pressure plate. A control circuit board is fixedly connected to the middle of the upper end of the inside of the top frame. A power-conducting telescopic head is electrically connected to the lower end of the control circuit board. A signal indicator light is fixedly connected to the middle of the front end of the top frame. The signal indicator light is electrically connected to the control circuit board. A lifting sleeve is fixedly connected to the middle of the upper end of the top frame. A threaded shaft is spirally connected to the inner side of the lifting sleeve. A control box is rotatably connected to the upper end of the threaded shaft. The mounting plate is fixedly connected to the upper end of the control box.

[0007] Furthermore, a telescopic support rod is fixedly connected to the upper outer side of the pressure plate, and the telescopic support rod is fixedly connected to the top frame. A first spring is provided inside the upper tube of the telescopic support rod.

[0008] Furthermore, an insulating plate is fixedly connected to the lower outer side of the energized telescopic head, and a second spring is fixedly connected to the upper outer side of the insulating plate. The second spring is fixedly connected to the control circuit board.

[0009] Furthermore, a power supply is fixedly connected to the inside right side of the top frame, and the power supply is electrically connected to the control circuit board and the power supply frame.

[0010] Furthermore, a first turntable is rotatably connected to the front left side of the control box, a worm gear is fixedly connected to the rear end of the first turntable, a worm wheel is meshed with the right end of the worm gear, and the worm wheel is fixedly connected to the threaded shaft.

[0011] Furthermore, a limiting telescopic rod is fixedly connected to the lower outer side of the mounting plate, and the limiting telescopic rod is fixedly connected to the top frame.

[0012] Furthermore, adjusting screws are spirally connected to both the left and right sides of the upper end of the top frame, a pressing block is fixedly connected to the lower end of the adjusting screw, and a second turntable is fixedly connected to the upper end of the adjusting screw.

[0013] The beneficial effects of this utility model are:

[0014] This invention utilizes a top frame and a support frame to support the aluminum electrolysis cell busbar. After adjustment with the top frame and support frame, raising or lowering the top frame (if not properly adjusted) allows the aluminum electrolysis cell busbar to press against the pressure plate, compressing the telescopic support rod and the first spring. Simultaneously, this brings the energizing frame into contact with the energizing telescopic head, compressing the second spring and energizing the control circuit board, thus illuminating the indicator light. When the top frame and support frame are lowered into position, the aluminum electrolysis cell busbar remains horizontal, releasing the pressure on the pressure plate and allowing the first and second springs to extend. This causes the indicator lights to lose power and stop illuminating, providing timely indication and improving the installation and adjustment efficiency of the aluminum electrolysis cell busbar frame. The invention utilizes the rotation of the first turntable to drive the worm gear to rotate, and limits the top frame via a limiting telescopic rod. This allows the threaded shaft to drive the lifting sleeve, top frame, and support frame to move up and down. The rotation of the second turntable causes the adjusting screw to move the top pressure block downwards, thus clamping and fixing the aluminum electrolysis cell busbar in conjunction with the support frame. This enables rapid fixing of the aluminum electrolysis cell busbar and improves post-installation stability. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Example 1 Figures 1-4 This utility model provides a technical solution:

[0023] A busbar frame lowering positioning indicator for an aluminum electrolysis cell includes a top frame 1, a support frame 2, and a mounting plate 11. The support frame 2 is fixedly connected to the lower end of the top frame 1. A pressure plate 3 is located at the middle of the lower end of the top frame 1. An electric frame 4 is fixedly connected to the middle of the upper end of the pressure plate 3. A control circuit board 5 is fixedly connected to the middle of the upper end inside the top frame 1. An electric telescopic head 6 is electrically connected to the lower end of the control circuit board 5. A signal indicator light 7 is fixedly connected to the middle of the front end of the top frame 1. The signal indicator light 7 is electrically connected to the control circuit board 5. A telescopic support rod 12 is fixedly connected to the outer side of the upper end of the pressure plate 3. The telescopic support rod 12 is fixedly connected to the top frame 1. A first spring 13 is located inside the upper tube of the telescopic support rod 12. An insulating plate 14 is fixedly connected to the outer side of the lower end of the electric telescopic head 6. A second spring 15 is fixedly connected to the outer side of the upper end of the insulating plate 14. The second spring 15 is fixedly connected to the control circuit board 5. The right side of the interior of the top frame 1 is fixedly connected to the support frame 2. A power supply 16 is connected, which is electrically connected to the control circuit board 5 and the power supply frame 4. The top frame 1 and the support frame 2 support the aluminum electrolytic cell busbar. After the top frame 1 and the support frame 2 are adjusted, the lifting and lowering of the top frame 1 (which is not in the correct position) causes the aluminum electrolytic cell busbar to press against the pressure plate 3, which compresses the telescopic support rod 12 and the first spring 13. At the same time, the power supply frame 4 contacts the power supply telescopic head 6, which compresses the second spring 15, thereby energizing the control circuit board 5 and causing the indicator light 7 to light up. After the top frame 1 and the support frame 2 are lowered into place, the aluminum electrolytic cell busbar remains horizontal, the pressure plate 3 is released, the first spring 13 and the second spring 15 extend, and the indicator light 7 loses power and stops illuminating. This provides timely indication and improves the installation and adjustment efficiency of the aluminum electrolytic cell busbar frame.

[0024] Please refer to Example 2 Figure 1 , Figure 2 and Figure 4The difference between this embodiment and Embodiment 1 is as follows: a lifting sleeve 8 is fixedly connected to the middle of the upper end of the top frame 1. A threaded shaft 9 is spirally connected to the inner side of the lifting sleeve 8. A control box 10 is rotatably connected to the upper end of the threaded shaft 9. A mounting plate 11 is fixedly connected to the upper end of the control box 10. A first turntable 17 is rotatably connected to the left front end of the control box 10. A worm gear 18 is fixedly connected to the rear end of the first turntable 17. A worm wheel 19 is meshed with the right end of the worm gear 18. The worm wheel 19 is fixedly connected to the threaded shaft 9. A limit telescopic rod 20 is fixedly connected to the outer side of the lower end of the mounting plate 11. The limit telescopic rod 20 is fixedly connected to the top frame 1. Both the left and right sides of the upper end of the top frame 1 are... The screw connection includes an adjusting screw 21, with a top pressure block 22 fixedly connected to the lower end of the adjusting screw 21 and a second turntable 23 fixedly connected to the upper end of the adjusting screw 21. The rotation of the first turntable 17 causes the worm gear 18 to drive the worm wheel 19 to rotate, and the limiting telescopic rod 20 limits the top frame 1, thereby allowing the threaded shaft 9 to drive the lifting sleeve 8, the top frame 1, and the support frame 2 to move up and down. The rotation of the second turntable 23 causes the adjusting screw 21 to drive the top pressure block 22 to move down, thereby cooperating with the support frame 2 to clamp and fix the aluminum electrolytic cell busbar, thus enabling rapid fixing of the aluminum electrolytic cell busbar and improving the stability after installation.

[0025] The working principle of this utility model is as follows: In use, the top frame 1 and support frame 2 support the aluminum electrolysis cell busbar. After adjustment of the top frame 1 and support frame 2, the raising and lowering of the top frame 1 (if not properly adjusted) causes the aluminum electrolysis cell busbar to press against the pressure plate 3, compressing the telescopic support rod 12 and the first spring 13. Simultaneously, this brings the energizing frame 4 into contact with the energizing telescopic head 6, compressing the second spring 15, thus energizing the control circuit board 5 and causing the indicator light 7 to illuminate. When the top frame 1 and support frame 2 are lowered into position, the aluminum electrolysis cell busbar remains horizontal, releasing the pressure on the pressure plate 3, and further energizing the first spring 13 and... The second spring 15 can extend, thereby causing the indicator light 7 to lose power and stop illuminating, providing timely indication and improving the installation and adjustment efficiency of the aluminum electrolysis cell busbar frame. The rotation of the first turntable 17 causes the worm gear 18 to drive the worm wheel 19 to rotate, and the limiting telescopic rod 20 limits the top frame 1, thereby allowing the threaded shaft 9 to drive the lifting sleeve 8, the top frame 1, and the support frame 2 to move up and down. The rotation of the second turntable 23 causes the adjusting screw 21 to drive the top pressure block 22 to move down, thereby cooperating with the support frame 2 to clamp and fix the aluminum electrolysis cell busbar, thus enabling rapid fixing of the aluminum electrolysis cell busbar and improving the stability after installation.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
