[0030] The arc-shaped shell 1 is provided with a plurality of groups, and the plurality of arc-shaped shells 1 are not in contact. The arc-shaped shell 1 is fixedly connected with a connecting seat 3 at two ends respectively. The arc-shaped shell 1 is abutted with a base 2 at the bottom end. The fixed plate 11 is connected with the connecting seat 3 in a matched mode. The fixed plate 11 is fixedly connected with a limiting column 9 at the bottom end. The limiting column 9 is connected with the connecting seat 3 in a matched mode. When the staff member assembles the plurality of arc-shaped shells 1 on the electrode of the submerged arc furnace, the base 2 is first sleeved and installed at the bottom of the electrode of the submerged arc furnace. Then, the plurality of arc-shaped shells 1 are sequentially placed on the base 2. The base 2 provides a supporting effect for the bottom end of the arc-shaped shell 1. After the plurality of arc-shaped shells 1 are assembled on the electrode of the submerged arc furnace, the staff member installs the fixed plate 11 on the connecting seat 3. The fixed plate 11 limits the connecting seat 3, thereby avoiding the overturning of the arc-shaped shell 1. The cooperation of the fixed plate 11 and the connecting seat 3 can avoid the use of welding to fix the arc-shaped shell 1 on the electrode of the submerged arc furnace. When the arc-shaped shell 1 is overhauled, the fixed plate 11 is removed from the connecting seat 3, and the arc-shaped shell 1 can be removed from the base 2. The time for disassembling the arc-shaped shell 1 is saved, and the high temperature does not cause more serious deformation of the welded arc-shaped shell 1. When the plurality of arc-shaped shells 1 are installed on the base 2, there is a gap between the plurality of arc-shaped shells 1. The space for thermal expansion of the arc-shaped shell 1 is avoided, and the mutual extrusion deformation of the plurality of arc-shaped shells 1 during thermal expansion is avoided.

When the fixed plate 11 is installed on the connecting seat 3, the limiting column 9 fixed by the fixed plate 11 is installed on the connecting seat 3. The staff member controls the locking assembly to fix the limiting column 9, thereby fixing the fixed plate 11 on the connecting seat 3. The limiting column 9 and the fixed plate 11 do not fall off from the connecting seat 3.

[0032] In some specific embodiments, a plurality of positioning holes 13 are formed in the bottom of the arc-shaped shell 1. A plurality of positioning columns 14 are fixedly connected to the top end of the base 2. The positioning holes 13 are matched with the positioning columns 14.

When the arc-shaped shell 1 is installed on the base 2, the positioning column 14 fixed to the top end of the base 2 is inserted into the positioning hole 13. The positioning column 14 provides a positioning supporting effect for the arc-shaped shell 1 by abutting against the inner wall of the positioning hole 13. The arc-shaped shell 1 is conveniently installed on the base 2. When the fixed plate 11 is installed on the connecting seat 3, the stability of the arc-shaped shell 1 does not need to be controlled by the staff member. The labor cost is saved. The shape of the base 2 ensures that the base 2 provides a limiting supporting effect for the bottom of the arc-shaped shell 1. The round corner 15 formed in the top of the base 2 facilitates the installation of the arc-shaped shell 1. The inner edge of the top of the base 2 does not abut against and rub against the bottom end of the arc-shaped shell 1. The round corner 15 has a guiding effect.

[0034] In some specific embodiments, the bottom of the limiting column 9 is provided with a locking hole 7, the connecting seat 3 is longitudinally provided with a limiting hole 8, the inner wall of the limiting hole 8 is connected with the limiting column 9, the locking hole 7 is connected with a locking assembly, the locking assembly comprises a spring 4, a locking rod 5 and a locking plate 6, the locking rod 5 is connected with the locking hole 7, the locking plate 6 is fixedly connected with the bottom end of the connecting seat 3, the two ends of the spring 4 are fixedly connected with the locking rod 5 and the locking plate 6 respectively, when the limiting column 9 is inserted into the limiting hole 8, the staff pulls the locking rod 5 away from the connecting seat 3, when the limiting column 9 is completely inserted into the limiting hole 8, the staff releases the locking rod 5, the spring 4 is always in a tension state, the elastic force of the spring 4 pulls the locking rod 5 to pass through the locking hole 7, the locking rod 5 and the inner wall of the locking hole 7 are abutted, thereby providing a limiting effect for the limiting column 9, thereby fixing the fixing plate 11 in the fixing groove 12, the spring 4 ensures that the locking rod 5 cannot automatically pop out of the locking hole 7, thereby achieving the locking effect of the limiting column 9 and the fixing plate 11.
