Description

Technical Field

[0001] This invention relates to the technical field of cathode carbon block assembly installation in electrolytic cells, and in particular to a cathode carbon block assembly installation fixture and its usage method. Background Technology

[0002] During the installation of cathode carbon block assemblies, due to their structural characteristics and the limitations of the installation environment, traditional installation methods are prone to the following problems: they are easily damaged by impacts. The cathode carbon block assembly is relatively brittle, and if there is a lack of effective protection or auxiliary tools during hoisting, alignment, and adjustment, it is easy to collide or rub against surrounding equipment, structural components, or other carbon block assemblies, resulting in chipped corners, cracks, or even breakage of the carbon blocks, directly causing the carbon block assembly to be scrapped, increasing material waste and costs. Summary of the Invention

[0003] In order to solve the problems existing in the prior art, the present invention provides an installation jig and a method of using it to protect the carbon block assembly when moving the carbon block assembly.

[0004] The present invention provides a cathode carbon block assembly mounting fixture, which adopts the following technical solution: A cathode carbon block assembly mounting fixture includes a support frame and a connecting rod assembly. Two support frames are arranged in parallel and connected by the connecting rod assembly. Each support frame includes two first angle steels arranged vertically. A second angle steel is fixed to the top of each first angle steel, and a lifting ring is fixed to the second angle steel. The connecting rod assembly includes a connecting block, a threaded connecting rod, and a locking nut. One threaded connecting rod corresponds to two connecting blocks. The connecting blocks are fixed to the outer side wall of the first angle steel. Both ends of the threaded connecting rod pass through the corresponding connecting blocks and are threaded to the locking nuts. Locking nuts are provided in both the front and rear directions of the connecting blocks. Multiple supporting reinforcing bars are fixed to the two inner sides of the first angle steel and are evenly distributed vertically. The side wall of the cathode carbon block assembly has openings for the supporting reinforcing bars to be inserted into the mounting groove.

[0005] Optionally, a buffer assembly is provided on the outer side wall of the first angle steel. The buffer assembly includes a spring and a baffle. One end of the spring is fixed to the outer side wall of the first angle steel, and the other end of the spring is fixed to the baffle.

[0006] Optionally, a reinforcing rod is provided below the second angle steel, with both ends of the reinforcing rod being fixed to two first angle steels of the same support frame.

[0007] A method for using a cathode carbon block assembly mounting fixture includes the following steps: S1. Assemble the fixture for the cathode carbon block assembly according to the drawings; S2. Adjust the fit between the fixture and the cathode carbon block assembly according to the actual size of the cathode carbon block assembly; S3. Combine the adjusted fixture with the cathode carbon block assembly, and install the cathode carbon block assembly into the fixture. S4. Using an on-site overhead crane, the jig and cathode carbon block assembly are hoisted into the electrolytic cell. After placing the jig in the designated position in the electrolytic cell, the locking nut is loosened to allow the support frame to detach from the cathode carbon block assembly.

[0008] Compared with the prior art, the present invention has the following technical effects: The fixture developed in this invention reduces material loss in the cathode carbon block assembly, simplifies and facilitates the construction process, and improves the installation efficiency and accuracy of the cathode carbon block assembly.

[0011] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 The present invention will be described in further detail below.

[0012] Reference Figures 1-5 This invention discloses a cathode carbon block mounting fixture, including a support frame 1 and a connecting rod assembly 2. Two support frames 1 are arranged in parallel and connected by the connecting rod assembly 2. Each support frame 1 includes two first angle steels 11 arranged vertically, and a second angle steel 12 is fixed to the top of each first angle steel 11. A lifting ring 121 is fixed to the second angle steel 12 for easy overhead crane lifting.

[0013] The connecting rod assembly 2 includes a connecting block 21, a connecting threaded rod 22, and a locking nut 23. One connecting threaded rod 22 corresponds to two connecting blocks 21. The connecting blocks 21 are fixed to the outer wall of the first angle steel 11. Both ends of the connecting threaded rod 22 pass through the corresponding connecting blocks 21 and are threadedly connected to the locking nuts 23. Locking nuts 23 are provided in both the front and rear directions of the connecting blocks 21. Adjusting the position of the locking nuts 23 adjusts the distance between the two support frames 1, thus accommodating cathode carbon blocks of different lengths.

[0014] Multiple supporting steel bars 111 are fixed on both inner sides of the first angle steel 11. The multiple supporting steel bars 111 are evenly distributed vertically. The side wall of the cathode carbon block assembly 5 is provided with a mounting groove 51 for the supporting steel bars 111 to be inserted. When installing the cathode carbon block assembly 5 into the fixture, first tighten the locking nut 23 towards both ends of the connecting threaded rod 22 so that the cathode carbon block assembly 5 can be placed between the two support frames 1. Then move the support frame 1 so that the supporting steel bars 111 are inserted into the corresponding mounting groove 51. Finally, tighten the locking nut 23.

[0015] A buffer assembly 4 is provided on the outer side wall of the first angle steel 11. The buffer assembly 4 includes a spring 42 and a baffle 41. One end of the spring 42 is fixed to the outer side wall of the first angle steel 11, and the other end of the spring 42 is fixed to the baffle 41. When the cathode carbon block assembly 5 is hoisted or moved, if the two ends of the jig length come into contact with other objects, the spring 42 and the baffle 41 can play a buffering and protective role, reducing the possibility of damage to the cathode carbon block.

[0016] A reinforcing rod 3 is provided below the second angle steel 12. The two ends of the reinforcing rod 3 are fixed to the two first angle steels 11 of the same support frame 1, which increases the stability of the support frame 1.

[0017] This invention also discloses a method for using a cathode carbon block assembly, comprising the following steps: S1. Assemble the fixture for cathode carbon block group 5 according to the drawings; S2. Adjust the fit between the jig and the cathode carbon block assembly 5 according to the actual size of the cathode carbon block assembly 5. S3. Combine the adjusted fixture with the cathode carbon block assembly 5, and install the cathode carbon block assembly 5 into the fixture. S4. Using an overhead crane for on-site construction, the jig and cathode carbon block assembly 5 are hoisted into the electrolytic cell. After placing the jig in the designated position in the electrolytic cell, the locking nut 23 is loosened to allow the support frame 1 to detach from the cathode carbon block assembly 5.

[0018] This invention reduces material loss in the cathode carbon block assembly, simplifies and simplifies the construction process, and improves the installation efficiency and accuracy of the cathode carbon block assembly.

[0019] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
