Description

TECHNICAL FIELD

[0001] The utility model relates to building structure technical field especially relates to a protection device for tower crown material transportation. BACKGROUND

[0002] In super high-rise building and large steel structure engineering, the steel beam hoisting construction of the tower crown part is one of the core links. The common tower crown steel beam (such as H-shaped steel beam, box type steel beam) because of the right angle structure of the section and the huge weight (usually up to several tons to several dozen tons), in the hoisting process, the hoisting cable directly contacts the right angle edge of the steel beam, and long-term bears high-strength shearing force and friction. In traditional construction, ordinary cable sheath or rubber gasket is usually used to protect the cable, but these methods have significant defects:

[0003] The sheath is poor in adhesion with the steel beam: the traditional plane sheath cannot tightly wrap the right angle edge of the steel beam, so that the cable still directly contacts the sharp part, and the sheath is easy to be cut and damaged.

[0004] The fixing mode is unreliable: most sheaths are fixed by a belt or a bolt, which is easy to shift or even fall off under the action of hoisting vibration and high-altitude wind, causing high-altitude falling risk.

[0005] The adaptability is insufficient: the existing sheaths are mostly of general size, which is difficult to adapt to the right angle size (such as 50mm to 200mm edge width) of different specifications of steel beams, resulting in uneven protection effect.

[0006] There is a lack of double protection mechanism of rapid installation and anti-falling in the prior art. The position of the sheath needs to be adjusted repeatedly in construction, which consumes time and effort and seriously affects the engineering efficiency. Especially in the complex scene of diagonal grid structure tower crown, the angle of the steel beam changes frequently, and the rigid structure of the traditional sheath cannot adaptively adjust the angle, further increasing the construction difficulty.

[0007] Therefore, it is urgent to provide a protection device that can tightly adhere to the right angle edge of the steel beam, be quickly fixed and have anti-falling function, to solve the risk of cable cutting and the hidden danger of high-altitude falling, and at the same time improve the hoisting efficiency and construction safety.
