The included angle between two adjacent support rods 3 is 30°, and the bodies of two adjacent support rods 3 are connected by reinforcing rods 6.

[0028] Positioning bracket 4 is connected to the ends of the two symmetrical support rods 3, and positioning bracket 5 is connected to the ends of the remaining support rods 3.

[0029] The positioning frame 4 includes an upper positioning plate 401 and a lower positioning plate 402, which are connected by an intermediate upright plate 403. The lower positioning plate 402 has a mounting hole 404 and is bolted to the end of the support rod 3. Both the upper positioning plate 401 and the lower positioning plate 402 have a slot 407 on their end faces away from the support rod 3.

[0030] A side support plate 405 is provided between the upper positioning plate 401 and the lower positioning plate 402. The outer wall of the side support plate 405 is welded to the upper positioning plate 401, the lower positioning plate 402 and the intermediate upright plate 403.

[0031] The upper positioning plate 401 has grooves 406 at the positions corresponding to the mounting holes 404.

[0032] The positioning frame 2 5 includes an upper positioning plate 2 501 and a lower positioning plate 2 502. The upper positioning plate 2 501 and the lower positioning plate 2 502 are connected by an intermediate upright plate 2 503. The lower positioning plate 2 502 is provided with a mounting hole 2 504. The lower positioning plate 2 502 is connected to the end of the support rod 3 by bolts. The upper positioning plate 2 501 and the lower positioning plate 2 502 are both provided with a slot 2 507 on the end face away from the support rod 3.

Then, another central circular plate 1 is fitted onto the other end of the central tube through the through hole 2 and positioned by a key, so that the two central circular plates 1 are set parallel to each other. Then, the square tube is placed in the upper and lower corresponding slots and welded. After the square tubes are welded, the rectangular tubes are welded together laterally. After the welding is completed, the positioning frames 1 4 and positioning frames 2 5 are removed. Then, the upper central circular plate 1 is removed and the central tube is taken out. Then, the welded extra-long cage is lifted by a crane, the lower central circular plate 1 is removed, and then the extra-long cage is placed stably on a flat place by a crane to prevent it from tilting or deforming.
