Description

Safety hoisting indicating device for bell-type furnace Technical Field The utility model belongs to the technical field of bell-type furnaces, and particularly relates to a safety hoisting indicating device of a bell-type furnace. Background Annealing after rolling is an indispensable procedure for the copper and copper alloy processing industry, and most enterprises adopt a cover type annealing treatment for rolled strips so as to achieve the purposes of eliminating residual stress of the strips and refining grains. The existing bell-type furnace cooling cover and heating cover are hoisted, lifting lugs (rings) are welded and installed on the top of the cover body, and a bridge crane hook head penetrates through the lifting lugs (rings) to finish hoisting operation, if the crane hook head does not completely penetrate through the lifting lugs, shaking can occur in the hoisting process, and overturning accidents can occur in severe cases. The height of the heating cover and the cooling cover of the bell-type furnace is higher, the size is larger, the lifting risk is larger, the production cost is reduced in order to improve the production efficiency, the charging amount of the bell-type furnace is usually more than 4 rolls, for example, the charging amount of the bell-type furnace is calculated according to 4 rolls of charging materials, the height of the heating cover and the cooling cover is more than 3 meters (along with the increase of the charging material rolls, the heights of the heating cover and the cooling cover are increased), the height is completely beyond the sight of people, and the observation of the personnel is limited to a certain extent. The hoisting operation risk is higher, and based on the problem, the safety hoisting indicating device of the bell-type furnace is designed. Disclosure of utility model The utility model aims to provide a safe hoisting indicating device for a bell-type furnace, which aims to solve the technical problem that personnel cannot accurately observe the hanging state of a hook head and a hanging ring due to the higher height of a cover body in the background art. In order to achieve the above purpose, the utility model adopts the following technical scheme: The utility model provides a bell-type furnace safety lifts by crane indicating device, includes the cover body, the cover body top is equipped with rings, and the cover body is equipped with indicating device, indicating device includes the weight, turns over the board and sets up in the backup pad of rings one side, the backup pad interval sets up two sets of, and the pivot of being connected rather than rotating is worn to establish on the upper portion of backup pad, one side backup pad is worn out to pivot one end to its tip passes through the rope and connects the weight, the edge of the cover body is equipped with the uide bushing that is used for supplying the rope to pass, and the vertical lateral wall of the cover body is located the uide bushing below and is equipped with the position sleeve, the weight slides and wears to locate in the position sleeve, turn over the board and set up in the pivot, turn over the board and be located one side of rings for with the gib head cooperation drive pivot of hoist, the rope pulls the weight and removes.
