[0002] Tower crane, also known as tower crane, originated in Western Europe. It 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. Due to the importance and particularity of tower cranes, in order to ensure construction safety during use, a protective fence is usually set at the bottom of the tower crane to warn construction workers.

[0003] A tower crane protection device disclosed in publication number CN218320461U, although, by connecting and fixing multiple enclosures in sequence, and then supporting the enclosures with support rods, there is no need to drill holes on the hard ground, and the protective enclosures can be installed and fixed. It has a wider range of applications, and each component of the enclosure can be disassembled, which is more convenient for storage or transportation.

[0004] However, the tower crane protection device has the following disadvantages:

[0005] (1) The staff cannot guard the tower crane base 24 hours a day, and the ordinary protective fence cannot prevent people from maliciously climbing over the protective fence and causing damage to the tower crane;

[0006] (2) The lack of a structure to increase the fault tolerance threshold of the alarm structure may cause the alarm structure to be triggered due to animals or other objects approaching the tower crane base. Utility Model Content
