Abstract
Description
Technical Field
[0001] The utility model relates to the field of container cranes, in particular to a lightning rod anti-falling device for container cranes and a lightning protection system thereof. Background Art
[0002] At present, in the manufacturing process of container cranes, there are usually two ways to protect against lightning in quay cranes:
[0003] One is that the lightning rod is directly connected to the main structure, and the lightning is directly led to the ground from the main structure and the structural parts across the grounding wire;
[0004] The other is a lightning protection system, in which the lightning rod is separated from the main structure and led to the ground through a separate lightning conductor outside the structure.
[0005] Generally speaking, for high-altitude lightning rods, effective anti-fall measures must be taken to prevent the lightning rods from falling and causing irreparable losses.
[0006] However, the following problems usually occur during the installation of lightning rod anti-fall wire:
[0007] In the form where the lightning rod is directly connected to the structure, there is no problem in installing the anti-fall wire. However, in the form where the lightning rod is connected via a separate lightning conductor, the lightning rod cannot be directly tied and fixed using the anti-fall wire.
[0008] Moreover, since the anti-fall wire is a metal device, direct installation will cause the lightning rod to come into contact with the structure. As a result, when the lightning rod attracts lightning, the lightning will pass through the structure, causing damage to equipment or safety hazards to personnel.
[0009] In order to avoid the above problems and ensure the safety of the lightning rod in the lightning protection system, the inventor of the present application has designed a lightning rod anti-falling device for a container crane and a lightning protection system thereof, in order to overcome the above technical problems.
