[0002] In the aluminum electrolysis industry, a certain specification of cathode carbon blocks is required in the pre-anode electrolysis cells used in aluminum electrolysis plants. During the manufacturing process of cathode carbon blocks, due to the requirements of different production processes, fixtures are needed to lift the cathode carbon blocks. Before lifting, the carbon blocks need to be tied up, and then the carbon blocks are lifted with the hook claws.
[0003] When implementing this technical solution, at least the following defects still exist: Existing lifting equipment usually uses fixtures to fix cathode carbon blocks before lifting. However, when the fixtures fix the cathode carbon blocks, it is usually necessary to manually or electrically control the fixtures for the cathode carbon blocks, which is too cumbersome, and it is inconvenient to ensure the stability of the lifting of the cathode carbon blocks. Therefore, improvement is urgently needed. For this reason, we propose a cathode carbon block clamp for an aluminum electrolysis cell. Content of the Utility Model

At the same time, the rubber strips on the clamping plate can be stuck into the grooves of the cathode carbon block, and in cooperation with the reinforcing rods penetrating through the middle of the rubber strips, the stability of the clamping of the clamping plate on the cathode carbon block is ensured, thereby ensuring the stability of the lifting of the cathode carbon block.
[0007] Optionally, a return spring is arranged on the inner side of the clamping plate, and both ends of the return spring are fixedly connected to the upper inner end of the clamping plate respectively.
[0008] By adopting the above technical solution, through the arrangement of the reset spring, the clamping plate can be driven to separate from the cathode carbon block, thereby facilitating the use of the cathode carbon block.
[0009] Optionally, the rubber strips are evenly distributed, and a reinforcing rod is arranged through the middle of the rubber strips.
[0010] By adopting the above technical solution, it is convenient to arrange the rubber strips, so that the rubber strips can be clamped into the grooves of the cathode carbon block, thereby limiting the cathode carbon block.
[0011] Optionally, the size of the slider is adapted to the size of the sliding groove, and the slider is slidably connected to the sliding groove.
[0012] By adopting the above technical solution, through the cooperation of the slider and the sliding groove, the stability of the movement of the clamping plate can be ensured.

[0014] By adopting the above technical solution, it is convenient to arrange the balls, so that the smoothness of the contact between the first wedge block and the second wedge block can be ensured, and the second wedge block can be pushed.
[0015] Optionally, the inclined surface of the first wedge block corresponds to the inclined surface of the second wedge block.
[0016] By adopting the above technical solution, through the cooperation of the first wedge block and the second wedge block, the clamping plate can be pushed, and then the cathode carbon block can be clamped.
[0017] Compared with the prior art, the beneficial effects of the technical solution of the present application are as follows:

[0024] Please refer to Figures 1-3 This utility model provides a technical solution: a cathode carbon block fixture for an aluminum electrolysis cell, including a fixture platform 1. Clamping plates 11 are arranged on both sides of the lower end of the fixture platform 1. Slide blocks 12 are fixedly installed at the upper ends of the clamping plates 11. Slide grooves 13 are opened at the lower end of the fixture platform 1. A rubber plate 2 is adhesively bonded to the inner lower end of the clamping plate 11. A plurality of rubber strips 21 are adhesively bonded to the inner side of the rubber plate 2. A first wedge block 23 is fixedly installed on the outer side of the clamping plate 11. Fixed frames 3 penetrate through both sides of the fixture platform 1. A second wedge block 24 is fixedly installed at the lower end of the fixed frame 3. The size of the slide block 12 is adapted to the size of the slide groove 13, and the slide block 12 is slidably connected to the slide groove 13. By the cooperation of the slide block 12 and the slide groove 13, the stability of the movement of the clamping plate 11 can be ensured. A plurality of balls 4 are rotatably installed on the side of the second wedge block 24 close to the first wedge block 23, and the balls 4 are in contact with the outer side of the first wedge block 23. By the arrangement of the balls 4, the smoothness of the contact between the first wedge block 23 and the second wedge block 24 can be ensured, so as to push the second wedge block 24. The inclined surface of the first wedge block 23 corresponds to the inclined surface of the second wedge block 24. By the cooperation of the first wedge block 23 and the second wedge block 24, the clamping plate 11 can be pushed, and then the cathode carbon block can be clamped.
[0025] A return spring 5 is arranged inside the clamping plate 11. Both ends of the return spring 5 are fixedly connected to the upper inner end of the clamping plate 11. By the arrangement of the return spring 5, the clamping plate 11 can be driven to separate from the cathode carbon block, and then the use of the cathode carbon block is facilitated.
[0026] The rubber strips 21 are evenly distributed, and a reinforcing rod 22 is arranged through the middle of the rubber strip 21, so that through the arrangement of the rubber strip 21, the rubber strip 21 can be clamped into the groove of the cathode carbon block, and then the cathode carbon block can be limited.
[0027] During hoisting, first lift the fixture platform 1 to the outside of the cathode carbon block, and then lift the fixing frame 3 through the lifting rope. During the lifting process, the second wedge block 24 on the fixing frame 3 will push the first wedge block 23, and the first wedge block 23 will drive the clamping plate 11 to move towards the middle, so that the two clamping plates 11 clamp and limit the cathode carbon block, saving the trouble of the staff clamping and fixing the cathode carbon block manually or electrically. At the same time, during the clamping process of the clamping plate 11, the rubber strip 21 on the clamping plate 11 will be clamped into the groove of the cathode carbon block, and at the same time, it cooperates with the reinforcing rod 22 penetrating through the middle of the rubber strip 21, thus ensuring the stability of the clamping of the cathode carbon block by the clamping plate 11, and thus ensuring the stability of the hoisting of the cathode carbon block.
