Description

Technical Field

[0001] The utility model relates to the technical field of building safety construction, in particular to a fixed safety passage for a tower crane. Background Technique

[0002] In the current high-rise structure construction, the tower crane is the main vertical transportation equipment. The external protective framework is usually a full-steel climbing frame. The tower body is far from the main building structure. As the tower crane rises with the floors, the vertical height becomes higher and it is more difficult to climb. The entire boarding path will also become longer and longer. The difficulty for the tower crane operator to board the plane (enter the cab from the ground) increases, and it is difficult to ensure safety. In order to shorten the boarding distance, in some cases, a safety passage is erected on the floor close to the tower platform and extended to the steel frame outside the cab for clamping and fixing. Then, after the operator fastens the safety buckle, he can slowly pass through the passage to reach the cab. However, the existing passage structures are mostly straight ladder structures and cannot be bent, making it difficult to erect between floors with a certain height difference and the cab, and the applicable range is relatively narrow. In addition, the overall center of gravity of such extended passages needs to be inward, so the overall counterweight at the rear is relatively large, and it is difficult and restricted to transfer to higher floors.
