Embodiment 1

[0020] Such as Figures 1 to 5 As shown, a hoisting device for a serpentine tube panel includes two parallel circular bearing beams 1 with the same length, and a plurality of hooks 2 are sleeved on the circular bearing beams 1, where each circular bearing 13 hooks 2 are set on the beam 1, and at least two lifting lugs 3 are welded on the circular load-bearing beam 1. Here, two lifting lugs 3 are set on each circular load-bearing beam 1, and the lower end of the hook 2 is used for For hooking the elbows 9 at both ends of the serpentine tube panel; a circular beam 4 is arranged between the corresponding lifting lugs 3 on the two circular load-bearing beams 1, and the circular beam 4 passes through the lifting lugs 3 and is detachably connected Together, the detachable connection between them is realized by the positioning screw 5 horizontally arranged on the lifting ear 3. The positioning screw 5 passes through the lifting ear 3 to tighten the circular beam 4 and is perpendicula...

Embodiment 2

[0023] Such as Figures 1 to 5 As shown, on the basis of Example 1, in order to facilitate the unloading of the serpentine tube panel, to ensure that the hook 2 that has been detached from the elbow 9 will not accidentally repeatedly hook the elbow 9, two limit rods 7 are designed. The limit rod 7 is welded to the bottom end of the sleeve 8, and the sleeve 8 is sleeved on the circular beam 4, so that the limit rod 7 can move axially along the circular beam 4, and two sleeves are arranged on each circular beam 4. Tube 8, the same limit rod 7 is welded to the corresponding sleeve 8 bottoms on the two circular beams 4.

[0024] When unloading the serpentine tube panel, each hook 2 is separated from the elbow 9, and the hook 2 is rotated so that it rests on the limit rod 7, and then the device is lifted away from the serpentine tube panel area, so that the setting ensures It is guaranteed that the hook 2 will not be in a shaking state after being separated from the elbow 9, which...

Abstract

The invention relates to the technical field of garbage waste heat boiler air pre-heater manufacturing, and discloses a snakelike tube panel lifting device. The snakelike tube panel lifting device comprises two round bearing beams, the round bearing beams are sleeved with a plurality of lifting hooks, at least two lifting lugs are welded on each round bearing beam, and the lifting hooks can hook bends at two ends of a snakelike tube panel. The snakelike tube panel lifting device is simple in structure and convenient to operate, ensures the lifting stability of the snakelike tube panel, prevents the tube panel from deforming in the process of lifting, and ensures the quality of the tube panel.

Description

technical field [0001] The invention relates to the technical field of manufacturing an air preheater of a waste heat boiler, in particular to a hoisting device for a serpentine tube panel. Background technique [0002] At present, the large-scale trend of waste heat recovery boilers makes the air preheater equipment of waste heat recovery boilers more and more large, and the internal structure is complicated, which brings difficulties to product manufacturing. The heat exchange tube group is an important part inside the preheater, and its manufacture and assembly are the key factors of the product quality of the preheater. The serpentine tube panel has the characteristics of large plane size, poor rigidity, and easy deformation. When assembling the heat exchange tube group, the serpentine tube will be deformed during the general hoisting process, causing serious damage to the quality of the serpentine tube. This prevents the installation process from proceeding smoothly. ...
