The main machine is one of the core components of the wind turbine generator, the structure is complex, the assembly and test period is long, and the weight is increased gradually. It is generally necessary to produce at multiple sites simultaneously to meet production schedules. The host machine needs to use a traveling crane to carry out hoisting operation in the links of assembly, test and the like and transportation. Because the elevation angles required during the assembling and testing of the main machine are different, and the placing directions of the positions of the main hook and the auxiliary hook of the crane in different bases relative to the main machine are different, higher requirements are provided for the universality and the safety of the main machine hoisting operation.

In order to meet the assembly process and test requirements of the host machine, the transmission chain needs to be in a horizontal state during assembly of the host machine, and the transmission chain needs to have a specified elevation angle during testing. At present, the T-shaped hanging beam is mostly adopted to adjust the elevation angle of the main machine. The main machine is transferred to the testing link process from the assembling link, the three lifting belts on the upper part of the T-shaped hanging beam are all connected with the main hook of the traveling crane, the main hook of the traveling crane lifts the main machine by a single hook, one lifting belt is additionally arranged in the shackle of the elbow lifting lug of the main machine and is connected with the auxiliary hook of the traveling crane, and the elevation angle of the main machine is adjusted by the lifting of the auxiliary hook of the traveling crane. Because the relative positions of the main hook and the auxiliary hook of the traveling crane are fixed (for example, the main hook is on the right, the auxiliary hook is on the left, and the relative positions of the two hooks cannot be changed), the operation is only suitable for the condition that the gravity center of the main machine is positioned between the main hook and the auxiliary hook. The actual center of gravity position of the main machine is deviated from the design, and the elevation angle cannot be adjusted when the center of gravity of the main machine is positioned outside the main hook and the auxiliary hook. And two hanging straps are simultaneously threaded in one shackle of the elbow lifting lug, the space in the shackle is insufficient, the hanging straps are mutually abraded, and safety accidents caused by the breakage of the hanging straps can occur.

the hanging beam body 1 is of a box-type structure and is formed by welding steel plates, the steel plates are common materials on the market and are easy to purchase, welding and manufacturing are simple, and the bearing capacity of the box-type hanging beam is high.

Two groups of main hook hanging holes are arranged on the beam body of the hanging beam body 1, and the main

hook hanging holes

21 and 22 are respectively arranged on the beam body of the hanging beam body 1 and are symmetrically arranged relative to the center of the hanging beam body 1. The lifting beam is used for installing a shackle 6, a backing plate is arranged at a hanging hole of the main hook and is welded with the lifting beam body 1, and the shackle 6 is connected with a main hook (not shown in the figure) of the travelling crane through a hanging strip 7.

Two sets of auxiliary

hook hanging holes

31 and 32 are arranged on the beam body of the hanging beam body 1 and are symmetrically arranged relative to the center of the hanging beam body 1. The lifting device is used for installing the shackle 6, a base plate is arranged at the lifting hole of the auxiliary hook and is welded with the lifting beam body 1, and the shackle 6 is connected with the auxiliary hook (not shown in the figure) or the main hook of the travelling crane through the lifting belt 7 (the auxiliary hook is connected when the double hook is lifted, and the main hook is connected when the single hook is lifted).

The distance from the main hook lifting hole to the center of the lifting beam body 1 is smaller than the distance from the auxiliary hook lifting hole to the center of the lifting beam body 1, so that the main hook bearing capacity of the crane is larger than that of the auxiliary hook during lifting. Wherein the main hook hanging hole 21 is close to the auxiliary hook hanging hole 31, and the main hook hanging hole 22 is close to the auxiliary hook hanging hole 32.

The hook plate 4 is welded with two end faces of the hanging beam body 1, and reinforcing rib plates 8 are arranged on the hook plate for reinforcing the stability of the hook plate 4; big lifting hooks 9 are formed on two side edges of the lifting hook plate 4, and small lifting hooks 10 are additionally arranged on two side surfaces of each big lifting hook 9 for thickening, namely the small lifting hooks 10 are integrally attached to the big lifting hooks 9, so that the thickness of the two side surfaces of each big lifting hook 9 is increased to increase the bending radius of the hanging strip 7, and the hanging strip 7 is prevented from being broken due to stress concentration; the lifting hook plate 4 and the small lifting hook 10 are rounded, so that the lifting belt is prevented from being abraded, and accidents are prevented. The large lifting hook 9 directly hangs the hanging strip 7 without the shackle 6 and the like for switching, the installation is time-saving and labor-saving, and the hanging strip 7 is connected with the host 11.
