Abstract

The invention discloses a hoisting device for a fragile kettle tank top cover. The device comprises a neck pipe hanging bracket, a jacking air bag and a dual-purpose inflator, wherein the neck pipe hanging bracket comprises a double-screw swing pipe and a plurality of pairs of split neck hooks, the double-screw swing pipe is of a screw pipe structure, a lifting ring, an air bag inflation opening and an air bag outlet blowing opening are formed in the top end of a screw pipe, and an air bag storage bin is arranged at an inner cavity of the screw pipe; the jacking air bag is of a cylindrical bagbody or circular ring bag body structure and is sleeved with the air bag storage bin in the normal state, an inner cavity of the jacking air bag is inflated when the dual-purpose inflator is connected with the air bag inflation opening, and the jacking air bag is pushed out of the air bag storage bin when the dual-purpose inflator is connected with the air bag outlet blowing opening. According tothe embodiment of the invention, the plurality of pairs of split neck hooks are firmly connected with a round cover body in a balanced stress manner, and the jacking air bag drives the fragile top cover to be separated from a kettle tank in a manner of combining increased stress area and gradual gas pressurization, so that the condition that a neck-shaped material pipe is pulled and broken can beprevented; and the bottom of the circular cover body can be prevented from being bumped and damaged.

Description

technical field [0001] The invention belongs to a lifting and hoisting tool, in particular to a hoisting device for a fragile kettle top cover which prevents damage to the fragile kettle top cover during lifting and hoisting. Background technique [0002] In order to prevent chemical equipment from being corroded by corrosive chemical raw materials containing acid, alkali, salt, etc., on the top of the inner cavity of some heat exchangers, synthesis tanks, reaction kettles, etc. Broken kettle top covers, when performing maintenance work, these fragile kettle top covers must be taken out from the kettle inner cavity to clean up residues and maintain and eliminate defects. These fragile top covers have a circular cover body structure and the shape of the cover body is round and smooth. Neither the binding method can be used to set the hanging point, nor can the hanging point be set by welding and drilling methods. The neck type material pipe used for liquid vapor exchange is ...
