[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-4 A tool for safely adjusting the displacement of the busbar of an aluminum electrolytic cell comprises a top plate 1 and a jack 8. Two built-in grooves 2 are provided on the inner wall of the top plate 1. The inner walls of the two built-in grooves 2 are slidably connected with guide plates 3. The sides of the two guide plates 3 that are away from each other are fixedly connected with extension plates 4. By using the built-in grooves 2, the guide plates 3 can be guided and limited, thereby guiding the lateral movement of the extension plates 4.

[0024] The front sides of the two guide plates 3 are fixedly connected with the first threaded rod 5, and the front side of the top plate 1 is provided with a through hole 7. The outer surfaces of the two first threaded rods 5 are slidably connected with the inner walls of the through hole 7. The outer surfaces of the two first threaded rods 5 are threadedly connected with the threaded clamping ring 6, and the back sides of the two threaded clamping rings 6 are in contact with the front side of the top plate 1. By rotating the threaded clamping ring 6, the threaded clamping ring 6 can be in contact with or out of contact with the front side of the top plate 1, so that the threaded clamping ring 6 can be pressed against the top plate 1, thereby limiting the position of the guide plate 3 and the extension plate 4.

[0025] A pressure detection mechanism 9 is provided below the top plate 1, and the pressure detection mechanism 9 includes a positioning plate 901 and a trigger rod 905. The lifting end of the jack 8 is fixedly connected to the bottom surface of the positioning plate 901, and the top end of the trigger rod 905 is fixedly connected to the bottom surface of the top plate 1. A trigger alarm 904 is installed inside the positioning plate 901. The interior of the positioning plate 901 is slidably connected to two guide rods 902, and the top ends of the two guide rods 902 are fixedly connected to the bottom surface of the top plate 1. By using the two guide rods 902, the lifting and lowering of the top plate 1 can be guided, so that the top plate 1 can drive the trigger rod 905 straight downward to trigger the trigger alarm 904.

[0026] The outer surfaces of the two guide rods 902 are wrapped with springs 903, and the upper and lower ends of the two springs 903 are fixedly connected to the bottom surface of the top plate 1 and the upper surface of the positioning plate 901 respectively. By using the springs 903, a certain distance can be maintained between the top plate 1 and the positioning plate 901, so that the top plate 1 will drive the trigger rod 905 to trigger the trigger alarm 904 only after a specified pressure. The trigger alarm 904 can alarm after being pressed by the trigger rod 905, reminding the worker that the pressure is too high, so that the worker can react and avoid the top plate 1 damaging the busbar.

[0027] The bottom surface of the jack 8 is fixedly connected to the upper surface of the base plate 10. Four supporting legs 11 are fixedly connected to the bottom surface of the base plate 10. By using the four supporting legs 11, the base plate 10 can be firmly supported, which is more stable when adjusting the busbar.

[0028] Two moving mechanisms 12 are set inside the base plate 10. The moving mechanism 12 includes a turntable 1201 and a support plate 1203. Two moving wheels 1204 are installed on the bottom surface of the support plate 1203. When the moving wheels 1204 come into contact with the ground, the device will be lifted up, making it easier to move the device.

[0029] The bottom surface of the turntable 1201 is fixedly connected to the second threaded rod 1202, the outer surface of the second threaded rod 1202 is threadedly connected to the base plate 10, and the bottom end of the second threaded rod 1202 is rotatably connected to the support plate 1203. By using the turntable 1201, workers can easily rotate the second threaded rod 1202.

[0030] Two guide columns 1205 are fixedly connected to the upper surface of the support plate 1203, and the outer surfaces of the two guide columns 1205 are slidably connected to the base plate 10. By using the two guide columns 1205, the lifting and lowering of the support plate 1203 can be guided to avoid deviation when the support plate 1203 drives the two moving wheels 1204 to move.

[0031] Working principle: When it is necessary to adjust the displacement of the busbar of the aluminum electrolysis cell, first place the device at the displacement of the busbar of the aluminum electrolysis cell. By starting the jack 8, the pressure detection mechanism 9 and the top plate 1 can be driven to move upward, so that the busbar displacement can be lifted up to facilitate the workers to perform correction operations. When the support range required for the busbar displacement range is large, by rotating the threaded clamping ring 6, the threaded clamping ring 6 can no longer abut against the top plate 1. By moving the guide plate 3, the guide plate 3 can drive the extension plate 4 to move, thereby expanding the range of support for the busbar displacement. During the adjustment of the busbar displacement, the top plate 1 will move downward due to the pressure at the displacement. When the pressure on the top plate 1 is too large, it will squeeze the spring 903 to drive the trigger rod 905 to trigger the trigger alarm 904, which will alarm and remind the staff to perform protective operations in time to avoid damage to the busbar due to excessive pressure. After the adjustment is completed, the top plate 1 is retracted by starting the jack 8. By rotating the turntable 1201, the second threaded rod 1202 can be driven to rotate, which can drive the support plate 1203 to move downward, and finally the support plate 1203 and the two moving wheels 1204 can be brought into contact with the ground, so that the device can be moved conveniently.
