Before lifting the desulfurizing tower assembly 5, the locking assembly 38 releases the locking of the insert rod 365 and the storage barrel 363, then the existing crawler crane enables the boom 1 to drive the desulfurizing tower assembly 5 and the auxiliary clamping mechanism 3 to move along the direction shown in fig. 1, the boom 1 rotates around the lower end of the boom assembly 5 as a fulcrum, the lower end of the desulfurizing tower assembly 5 gradually moves towards the boom 1 under the action of gravity, the included angle between the top end of the desulfurizing tower assembly 5 and the boom 1 gradually decreases, meanwhile, under pushing of the lower end of the desulfurizing tower assembly 5, the horizontal straight line distance between the arc-shaped clamping seat 30 and the boom 1 gradually decreases, the arc-shaped clamping seat 30 and the insert rod 364 move towards the storage barrel 363, meanwhile, the electric sliding block 34 gradually slides upwards on the guide rail 2, and the included angle between the boom 1 and the fixing plate 362 is larger and larger, so that the fixing plate 362, the fixing column 360 and the connecting column 361 rotate around the hinge point of the fixing column 360 and the electric sliding block 34 to always keep the horizontal state, and the boom 1, the auxiliary clamping mechanism 3 and the desulfurizing tower assembly 5 always form a right-angle triangle structure, and the designated installation height of the desulfurizing tower assembly 5 moves until the right-angle triangle assembly 5 moves.
When the desulfurizing tower assembly 5 is assembled, the boom 1 drives the aligning rollers 312 at the bottoms of the desulfurizing tower assembly 5 and the arc-shaped clamping seat 30 to move towards the base barrel until the aligning rollers 312 at the bottoms of the arc-shaped clamping seat 30 are abutted against the outer side wall of the base barrel, so that the aligning of the desulfurizing tower assembly 5 and the base barrel is realized, and the convenience of installation and butt joint of the desulfurizing tower assembly 5 is improved.
