[0046] Specifically, based on the number and width of the roof purlins, a corresponding number of bottom lifting points can be determined on-site at the bottom of the I-shaped foundation frame 11 to ensure that the center position of the purlin module is located in the middle of the I-shaped foundation frame 11. The installation method of the second lower lifting lug 16 is the same as that of the first lower lifting lug 13 mentioned above. Each purlin is fixed to the bottom of the lifting frame 1 by the main rope and the branch rope, thereby further increasing the stability of the lifting and making it safer.

[0047] As a preferred embodiment of this utility model, the number of second lower lugs 16 is equal to the number of middle purlins 42, and the positions of the second lower lugs 16 and the middle purlins 42 correspond vertically.

[0048] Specifically, when there are multiple middle purlins 42, adjacent middle purlins 42 are connected and fixed by secondary beams 43. The second lower lifting lug 16 is used to fix the middle purlins 42 by ropes.

[0051] Specifically, the shackles facilitate the connection and disassembly of the main rope and the branch ropes. Depending on the actual site requirements, the length of the connection between the main rope and the branch ropes can be adjusted to avoid obstacles during hoisting.

[0052] As a preferred embodiment of this utility model, the first main rope body 21 and the second main rope body 24 are both slings; the first branch rope body 22, the second branch rope body 23, the third branch rope body 25, the fourth branch rope body, the first upper hoisting rope body 31 and the second upper hoisting rope body 32 are all steel wire ropes.

This utility model does not make any special limitation in this regard.

[0054] As a preferred embodiment of this utility model, the purlin module is located in the lower middle part of the hoisting frame 1.

[0055] This ensures structural symmetry, resulting in more even stress distribution on the purlin modules during hoisting.

[0056] As a preferred embodiment of this utility model, the length of the hoisting frame 1 is 12.5 ± 1 meters.

[0057] It should be noted that the length of the hoisting frame 1 is preferably, but not limited to, 12.5 ± 1 meters, and can be adjusted as needed.

[0058] When using the roof purlin module hoisting auxiliary device provided by this utility model, first assemble the purlin module, then weld the purlins to the secondary beam 43 in groups, and ensure the weld joints are protected against corrosion. Determine suitable bottom lifting points at the bottom of the I-beam foundation frame 11 to facilitate the welding of the first lower lifting lug 13 and the second lower lifting lug 16, ensuring the purlin module is positioned in the middle of the I-beam foundation frame 11 during hoisting. Depending on the installation of surrounding components at the construction site, a main rope (which can be a sling or wire rope) can be added to the bottom lifting points to adjust the hoisting height of the purlin module and prevent collisions with surrounding installed components. Finally, secure the wire rope with a binding, attaching one end to the node plate where the roof corner brace is installed, and connecting the other end to the sling via a shackle. The purlin module is then lifted under the force of the first upper hoisting rope 31 and the second upper hoisting rope 32 at the top of the hoisting frame 1.

[0059] As can be seen from the above specific embodiments, the roof purlin module hoisting auxiliary device provided by this utility model, through the structural design of the hoisting frame, purlin module fixing mechanism, and frame hoisting mechanism, welds and fixes the roof purlins into a whole in a modular manner on the ground according to actual needs. Then, the two ends of the side purlins of the purlin module are fixed to the bottom of the hoisting frame by the purlin module fixing mechanism, and hoisting is carried out in the form of purlin modules. The hoisting efficiency is high, and the fixing method of the main rope plus two branch ropes makes the purlin position more stable during hoisting, avoids rotation and swaying, and has high safety. Moreover, by adjusting the length of the main rope, obstacles can be avoided during hoisting. This utility model has the advantages of simple structure, simple manufacturing and processing, convenient installation, high stability during hoisting, good safety, and high hoisting speed.
