Description

Technical Field

[0001] The utility model relates to the technical field of windproof devices for cranes, and more specifically to a windproof structure for tower cranes. Background Art

[0002] Tower crane, also known as tower crane, is a rotating crane with a boom mounted on the top of a tall tower. It has a large working space and is mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. The metal structure includes the tower, boom and base. The working mechanism has four parts: lifting, luffing, slewing and traveling.

[0003] When constructing a high-rise building, the height of the tower crane will increase with the height of the building. The main body of the crane is located at the top of the tower. When the wind blows, it is inevitable that the surface will shake. In windy weather, the shaking will be more severe, which poses certain safety hazards. Therefore, a reinforcement device is needed to reinforce the crane against wind and improve the safety of the main body of the crane when it is working at high altitude.

[0004] At present, the windproof structure of existing tower cranes is mostly fixed by the bottom fixing seat or external traction. The height adjustment effect of conventional traction is weak. Secondly, the ends of conventional traction ropes are connected to the gripping components fixed on the ground. When the traction angle is adjusted in advance, the position of the gripping components needs to be adjusted first, which is cumbersome and has a low fault tolerance rate. In view of this, we propose a crane windproof device. Utility Model Content
