Description

Technical Field

[0001] The invention relates to the technical field of hoisting in the construction industry, and in particular to a steel shoulder pole for high-altitude hoisting and installation. Background Art

[0002] According to the process design requirements, most of the industrial plants in the building industry adopt the portal frame structure of multi-span continuous beams. The conventional installation method is: use at least two cranes to use a single I-beam (with large cross-sectional inertia moment) as a lifting steel pole, and each hoist a single-span beam. After aligning it in place at high altitude, the beams and beams and columns are bolted together with high-strength bolts. At present, at least two cranes are used to use a single I-beam as a lifting device to hoist a single-span beam. After aligning it in place at high altitude, the beams and beams and columns are bolted together. This method requires the cooperation of multiple cranes, and it is difficult to align it in place at high altitude. The installation deviation is large and needs to be adjusted repeatedly. Due to the insufficient load capacity of the single I-beam lifting device of the adapted specifications, it is easy to bend and become unstable, and it is impossible to realize the lifting of multi-span continuous beams (increasing the cross-sectional specifications is not economical). The quality of the superimposed combination welding is difficult to guarantee and is not economical. The personnel need to operate a wide range of procedures at high altitude, which takes a long time and has high safety risks, affecting the smooth progress of the installation and construction progress, quality and safety goals.

[0003] In order to solve the problem of single I-beam hangers being easy to bend, Chinese patent CN203359759U proposes a double-row shoulder pole beam hanger, which includes two H-shaped steels and two lifting lug plates. The two H-shaped steels are used to stabilize the overall hanger, and the two H-shaped steels are fixedly connected by the two lifting lug plates. Chinese patent CN118723779A also proposes a structural combined crane beam, which is composed of two crane beams and a space truss between them to form an overall spatial structure, so that the two crane beams are jointly stressed and jointly resist external loads. However, in the double-row setting, the parts that are not fixed by the lifting lug plates are still weakly stressed, and the overall stability is not the same, and there is still a certain safety risk. Summary of the invention

[0004] In order to solve the problems of the prior art, the present invention proposes a steel shoulder pole for high-altitude lifting and installation that reduces high-altitude operations and is safe and stable. The specific technical solution is as follows:

[0008] Furthermore, the maximum spacing between the two full-length channel steel auxiliary support rods and the full-length I-beam main support rod is 300-600 mm.
