Description

Technical Field

[0001] This utility model relates to the field of aluminum electrolysis, and more specifically, to a special device for warning when a busbar lifting frame is lowered into position. Background Technology

[0002] Using alumina as the solute, carbon as the anode, and molten aluminum as the cathode, a strong direct current is applied, and an electrochemical reaction occurs at the two electrodes in the electrolytic cell under high temperature conditions; this is known as electrolysis.

[0003] The busbar lifting operation is one of the critical operations in the electrolysis workshop, and it has a significant impact on the safe production of the electrolytic cells. Once a problem occurs during the busbar lifting operation, serious accidents can easily occur, affecting the safety of the electrolytic cells. During the busbar lifting operation, after the busbar lifting frame is lowered into the upper tank, because the busbar lifting frame is relatively high, personnel standing below cannot accurately see whether the busbar lifting frame is fully in place. If it is not fully lowered, the busbar lifting frame will fall again after the small box clamp is released, causing an accident under the anode or damaging the overhead crane. Therefore, a special device for warning when the busbar lifting frame is fully lowered is proposed to solve the above problems. Utility Model Content

[0004] To overcome the problem that existing technologies make it difficult to observe whether the busbar lifting frame is in place, which can easily lead to falling accidents, this utility model provides a special device for warning when the busbar lifting frame is in place. The device includes a base plate, an electrolytic cell fixedly installed on the top of the base plate, a busbar grounding post fixedly installed on the top of the base plate, and a busbar fixedly connected to the side wall of the electrolytic cell. The device is characterized in that a lifting assembly is movably installed on the top of the base plate, and a positioning frame is fixedly installed on the top of the lifting assembly, with the busbar located inside the positioning frame.

[0005] Preferably, the lifting assembly includes a fixed base plate, which is movably mounted on the top of the base plate. A telescopic sleeve is fixedly mounted on the top of the fixed base plate, and a telescopic rod is movably mounted inside the telescopic sleeve. The positioning frame is fixedly mounted on the top of the telescopic rod.

[0006] Preferably, the positioning frame includes a frame, which is fixedly installed on the top of the telescopic rod. The frame is U-shaped, and a pressure sensor is fixedly installed on the inner wall of the frame. A limit plate is fixedly installed on the top of the frame, and the number of pressure sensors is three.

[0007] Preferably, the inner wall of the frame is fixedly installed with six movable components, with each pair of movable components forming a group. Each group of movable components has a movable plate fixedly installed at the end away from the inner wall of the frame. Three movable plates have pressure-sensitive posts fixedly installed on the side near the movable components. The three pressure-sensitive posts correspond to the positions of the three pressure-sensitive sensors.

[0008] Preferably, the movable component includes a sleeve fixedly installed on the inner wall of the frame. A spring seat is fixedly installed inside the sleeve, and a telescopic spring is fixedly installed inside the spring seat. A connecting plate is fixedly installed at the end of the telescopic spring away from the spring seat, and a movable rod is fixedly installed at the end of the connecting plate away from the telescopic spring. The end of the movable rod away from the connecting plate is fixedly connected to the movable plate. A sliding groove is provided on the side wall of the sleeve, and the connecting plate is slidably connected to the sliding groove.

[0009] Preferably, an audible and visual alarm is fixedly installed on the outer wall of the telescopic sleeve, and a microcontroller is provided on the side wall of the audible and visual alarm.

[0010] Preferably, the three pressure sensors are connected in parallel, and the three pressure sensors are electrically connected to the audible and visual alarm.

[0011] Preferably, the audible and visual alarm and the three pressure sensors are all electrically connected to a microcontroller.

[0012] Preferably, the end of the busbar furthest from the electrolytic cell is connected to the busbar grounding post, the busbar grounding post and the positioning frame are at the same horizontal level, and a crane hook is sleeved on the outside of the busbar.

[0013] Beneficial effects:

[0014] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0015] (1) By setting the U-shaped frame opening upwards, the busbar conveyed by the crane hook can easily fall into the frame. The inner wall of the frame is equipped with a pressure sensor, a triggering active component, an active plate, and a pressure post. The three pressure sensors are connected in parallel. After the busbar is completely lowered into the frame, the three pressure sensors will press and work at the same time. The single-chip microcomputer controller controls the sound and light alarm to alert the staff. At this time, the busbar and the busbar grounding post are at the same height. The staff can intuitively judge whether the busbar has been lowered into place and perform the connection work between the busbar grounding post and the busbar. This solves the problem of difficulty in judging whether the busbar has been lowered into place due to obstructed vision and avoids the risk of the busbar falling off when the crane hook is released.

[0016] (2) The frame can be adjusted in height by telescopic rod inside telescopic sleeve to ensure that the frame can be on the same horizontal line as the grounding post of the busbar for easy observation. The lifting component can be freely installed and removed. After the busbar of one slot is connected, it can be moved to the next slot for continued use.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments. The specific embodiments are as follows:

[0024] like Figures 1 to 3 As shown, a special device for warning when a busbar lifting frame is in position includes a base plate 1, an electrolytic cell 2 fixedly installed on the top of the base plate 1, a busbar grounding post 6 fixedly installed on the top of the base plate 1, and a busbar 3 fixedly connected to the side wall of the electrolytic cell 2. The device is characterized in that a lifting assembly 5 is movably installed on the top of the base plate 1, a positioning frame 7 is fixedly installed on the top of the lifting assembly 5, the busbar 3 is located inside the positioning frame 7, and the lifting assembly 5 includes a fixed base plate 50 movably installed on the top of the base plate 1. A telescopic sleeve 51 is fixedly installed on the top of the fixed base plate 50. The internal movable part of the 1 is equipped with a telescopic rod 52, and the positioning frame 7 is fixedly installed on the top of the telescopic rod 52. The telescopic rod 52 can adjust the height of the positioning frame 7. The end of the busbar 3 away from the electrolytic cell 2 is connected to the busbar grounding post 6. The busbar grounding post 6 and the positioning frame 7 are set at the same horizontal line. The busbar 3 is fitted with a crane hook 4. After adjustment by the telescopic rod 52, the inlet of the busbar grounding post 6 and the positioning frame 7 are at the same height. Therefore, it can be intuitively judged whether the busbar 3 has descended to the position and can be connected to the busbar grounding post 6 by whether the busbar 3 contacts the positioning frame 7.

[0025] In addition, the positioning frame 7 includes a frame 70, which is fixedly installed on the top of the telescopic rod 52. The frame 70 is U-shaped. A pressure sensor 71 is fixedly installed on the inner wall of the frame 70. A limit plate 72 is fixedly installed on the top of the frame 70. There are three pressure sensors 71. Six movable components 9 are fixedly installed on the inner wall of the frame 70. Each group of two movable components 9 is a group. A movable plate 10 is fixedly installed on the end of each group of movable components 9 away from the inner wall of the frame 70. A pressure post 11 is fixedly installed on the side of each of the three movable plates 10 near the movable components 9. The three pressure posts 11 correspond to the positions of the three pressure sensors 71. The frame 70 is U-shaped. When the crane hook 4 pulls the busbar 3 down, the shape of the frame 70 can easily adapt to the busbar 3, allowing it to fall into the range of the frame 70. Three sets of movable components 11 are installed on the inner wall of the frame 70. The system includes component 9, three pressure sensors 71, and three movable plates 10. Each movable plate 10 has a pressure post 11 on one side. When the busbar 3 enters the frame 70, it will squeeze the three movable plates 10, causing the movable component 9 to retract and touch the pressure sensor 71 through the pressure post 11. An audible and visual alarm 8 is fixedly installed on the outer wall of the telescopic sleeve 51. A microcontroller 12 is installed on the side wall of the audible and visual alarm 8. The three pressure sensors 71 are connected in parallel and electrically connected to the audible and visual alarm 8. The audible and visual alarm 8 and the three pressure sensors 71 are all electrically connected to the microcontroller 12. Since the three pressure sensors 71 are all pressured by the pressure post 11 and the busbar 3, the audible and visual alarm 8 will be activated. The operator can judge whether the busbar 3 has descended to the correct position by the operation of the audible and visual alarm 8, thus avoiding the problem of the busbar 3 falling after the crane hook 4 is released.

[0026] The movable component 9 includes a sleeve 90, which is fixedly installed on the inner wall of the frame 70. A spring seat 91 is fixedly installed inside the sleeve 90, and a telescopic spring 92 is fixedly installed inside the spring seat 91. A connecting plate 93 is fixedly installed at the end of the telescopic spring 92 away from the spring seat 91. A movable rod 94 is fixedly installed at the end of the connecting plate 93 away from the telescopic spring 92. The end of the movable rod 94 away from the connecting plate 93 is fixedly connected to the movable plate 10. A groove 95 is provided on the side wall of the sleeve 90, and the connecting plate 93... The sliding groove 95 is slidably connected. When the movable plate 10 is squeezed by the busbar 3, the telescopic spring 92 will contract and drive the connecting plate 93, the movable rod 94 and the movable plate 10 to move, so that the pressure post 11 can contact the pressure sensor 71. The limiting plate 72 serves to protect the movable plate 10 and the movable component 9 on both sides of the inner wall of the frame 70, so as to prevent the busbar 3 from being directly squeezed and damaged when entering the frame 70, and to ensure that the busbar 3 can safely fall into the frame 70, thereby ensuring that the connection with the busbar grounding post 6 is more convenient.

[0027] It should be noted that after the gantry hook 4 transports the busbar 3 to the protective frame 70, it is necessary to observe whether the audible and visual alarm 8 is running. Even if it is running, the gantry hook 4 should not be released directly. The positioning frame 7 and the lifting assembly 5 do not bear any force. After receiving the indication that the busbar 3 is in place, the other section of the busbar 3 is connected to the busbar grounding post 6. After the busbar grounding post 6 has completely fixed the busbar 3, the gantry hook 4 is released to ensure safety. After the busbar 3 of one slot is connected, the fixed base plate 50 can be moved to the next slot for repeated use. The operation is convenient and reliable.

[0028] Working principle: By setting a pressure sensor 71 on the inner wall of the frame 70, as well as a triggering movable component 9, movable plate 10 and pressure post 11, the lifting component 5 can freely adjust the installation position and height, so that the frame 70 can be adapted to the height of each busbar grounding post 6. After the busbar 3 is transported to the slot by the crane and crane hook 4, the connection work is carried out. When the busbar 3 enters the frame 70, it will press the pressure sensor 71. Only when the busbar 3 is fully in place, the three parallel pressure sensors 71 and the microcontroller 12 receive the signal and activate the sound and light alarm 8. After receiving the signal, the operator fixes one end of the busbar 3 to the busbar grounding post 6. After the work is completed, the lifting component 5 and the positioning frame 7 are moved to the next slot.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
