Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, especially a safety protection device for tower crane wall-attached rod. BACKGROUND

[0002] With the continuous progress of modern building technology, high-rise buildings have sprung up like mushrooms. The construction of these skyscrapers cannot be supported without the help of tower cranes (referred to as tower cranes). Tower cranes play a crucial role in building construction, as they are responsible for lifting building materials and also undertake tasks such as component installation. As the height of the building increases, the working range and load capacity of the tower crane also increase accordingly, which requires the tower crane to have higher stability and safety. To meet this demand, the design and function of the tower crane are constantly upgraded and improved.

[0003] When the tower crane reaches a certain working height, in order to ensure its stability and safety, it needs to be fixed to the building structure through an attachment device. This attachment usually involves multiple levels of connection, including the structure of the tower crane itself, the attachment rod, and the building structure itself. As the building height increases, the number of attachment points of the tower crane also increases, which undoubtedly increases the stability of the tower crane, but also brings new problems.

[0004] In actual operation, the maintenance of the tower crane attachment is a task that cannot be ignored. Since the attachment point is usually located on the outer gable of the building structure, this makes it difficult for workers to perform routine inspections and maintenance without a maintenance passageway, making it impossible to safely perform the work. In addition, when installing or disassembling the attachment rod, since the lifting lug of part of the rod is located in the middle of the rod, the worker needs to perform lifting point rope tying and untie operations when performing high-altitude operations, which not only increases the difficulty of the operation, but also increases the safety risk. More seriously, if the attachment rod is installed or disassembled, since the lifting lug of part of the attachment rod is located in the middle of the rod, the worker performs lifting point rope tying and untie operations, which is high-altitude operation, and the wall-attached rod has risks when it is not fixed to form a stable condition.

[0005] Therefore, in view of the above phenomenon, a safety protection device for the maintenance, installation and disassembly of the tower crane attachment needs to be designed. UTILITY MODEL CONTENTS
