Adjustable loading and unloading hanger for waste heat boiler module

Abstract

The invention relates to an adjustable loading and unloading hanging bracket of a waste heat boiler module. The adjustable loading and unloading hanging bracket comprises a main beam, a plurality of main beam lifting lugs at the upper end of the main beam, a sliding plate fixed at the lower end of the main beam, a plurality of long holes horizontally formed in the sliding plate, and a plurality of grooves formed in the bottom of the long holes, wherein each long hole is internally provided with an inverted U-shaped shackle I in a sliding manner, a bolt II is inserted in an opening in the lower end of each shackle I and is locked and fixed through a nut II, and a steel rope I is fixed at the lower end of each shackle I. The main beam is hung on hoisting equipment by steel wire ropes through the lifting lugs, and because the plurality of main beam lifting lugs are arranged at the upper end of the main beam, stress concentration is prevented. A plurality of steel wire ropes I at the lower end of the main beam are used for fixing and hoisting a waste heat boiler, and each steel rope I can slide along the corresponding long hole through the corresponding shackle I, and is arranged in the corresponding groove for realizing position adjustment and fixation, so that the adjustability of a hoisting point is improved, the convenience is brought for hoisting, and the hoisting efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of lifting tools, in particular to a hanger. Background technique [0002] The heating surface module of the waste heat boiler is mainly composed of rows of spiral finned tubes, which are in the shape of a cuboid as a whole, with a heavy weight of up to 100 tons, a large volume and a long length of up to tens of meters. Moreover, there is no rigid support in the middle part of the module, and the overall flexibility is relatively large. When this method is hoisted, the helical fin tube of the heating surface module is prone to deformation and other disadvantages during the hoisting process. And used loading and unloading device is very heavy, causes construction efficiency to reduce. [0003] Usually, two cranes are required to lift the heating module, and the construction cost is relatively high. And two cranes cooperate hoisting, there is bigger potential safety hazard, and danger easily occurs. Conte...

Problems solved by technology

And there is no rigid support in the middle part of the module, and the overall flexibility is relatively large

When this method is hoisted, the spiral fin tube of the heating surface module is prone to deformation and other disadvantages during the hoisting process

And the loading and unloading device used is very heavy, resulting in reduced construction efficiency

[0003] Usually, the hoisting of the heating module requires two cranes to complete the hoisting, and the construction cost is relatively high

In addition, two cranes cooperate with hoisting, which has great potential safety hazards and is prone to danger.
