In order to ensure that the waste heat boiler can be accurately and stably placed at the predetermined position during the hoisting process, it is necessary to position the waste heat boiler during hoisting. The existing waste heat boiler hoisting positioning device mainly sets up a bracket for positioning after measuring and marking the installation position. The waste heat boiler is lifted by a crane and then hoisted into the bracket. The bracket is removed after the waste heat boiler is installed.

[0003] Existing application number CN201720965451.8 The utility model relates to a hoisting tool for a waste heat boiler ascending and descending pipe, comprising two semicircular clamps (1), a fastening bolt (2), a top screw (3), a locking nut (4) and a lifting lug (5), wherein the two semicircular clamps (1) are respectively provided with bolt holes on both sides, and the two semicircular clamps (1) are connected by the fastening bolt (2), a plurality of top screws (3) are provided in the middle of one semicircular clamp (1), and a locking nut (4) is provided on the top screw (3) for locking and fixing the top screw (3), and a lifting lug (5) is vertically provided in the middle of the other semicircular clamp (1).

[0004] Based on the above, the positioning bracket of the existing waste heat boiler hoisting positioning device is usually erected or customized on site, which is inconvenient to adjust and is only suitable for the size of the installed waste heat boiler. The scope of application is limited, and it takes a lot of time to disassemble and assemble the positioning bracket. When a group of structural steel is used to install multiple groups of waste heat boilers, the positioning bracket needs to be moved frequently, which affects the installation efficiency of the waste heat boiler. In addition, the position of the waste heat boiler needs to be repeatedly adjusted during hoisting so that it can accurately fall into the positioning bracket. Utility Model Content
