Problems solved by technology
Put the hook across the furnace wall and tie the roller again to continue hoisting in place. Although this method can meet the installation requirements, the construction method is more complicated, time-consuming and labor-intensive, especially when driving to remove the hook. It is difficult to guarantee the safety

The invention specifically relates to a suspension tool used for hoisting of a furnace roller and a using method thereof. The suspension tool is characterized in that: the tool includes a furnace roller sleeve pipe, a lock nut, a lifting lug, and a counterweight member; wherein the head of the furnace roller sleeve pipe is of a diffusion shape, and an end surface of the diffusion shape head is further provided with an insertion hole with a diffusion-shaped opening; and the lock nut is disposed at an innermost end of the insertion hole and connected to the inner wall of the furnace roller sleeve pipe, the lifting lug is disposed on the outer wall of the furnace roller sleeve pipe, and the counterweight member is disposed on the tail of the furnace roller sleeve pipe. Through adoption of thedesign, a connection sleeve pipe is arranged at one end of the furnace roller and weighted, so that when hoisting is performed, suspension centers can be disposed on the center and a side end portionof the furnace roller to achieve the purpose of hoisting in place by one time, thereby enabling the safety and the construction efficiency of hoisting work of the whole furnace roller to be improved.
Description
technical field [0001] The invention relates to the field of installation of furnace rolls, in particular to a hoisting tool for hoisting furnace rolls and a use method thereof. Background technique [0002] The single weight of the continuous annealing furnace roller is about 10 tons, which is relatively heavy, and the two ends of the furnace roller are rolling bearings, so it is impossible to set the lifting point. Therefore, the hoisting operation usually uses the center of the roller as the lifting point, and the roller is tied with a sling for hoisting. When hoisting to the hoisting hole on the side of the furnace wall, the furnace roller cannot pass through the hoisting hole at one time, so the hoisting point can only be set inside the furnace wall. Chain hoists are used to assist hoisting, and temporary support points are set under the rollers, and then the hooks are removed by driving. Put the hook across the furnace wall and tie the roller again to continue hoistin...
