Description

Technical Field

[0001] The utility model relates to the technical field of crane protection, in particular to a typhoon protection device for a gantry crane used in coastal cities. Background Art

[0002] Gantry crane, also known as portal crane, usually refers to a shore crane with a large operating span, used for marshalling and stacking containers. It is widely used in ports in coastal cities. However, the gantry cranes currently in use have the structural disadvantage of being top-heavy and having a large windward area. When operating outdoors in coastal areas, there are certain safety hazards after being hit by typhoons.

[0003] In recent years, with the further development of relevant technologies, some typhoon protection devices for gantry cranes have appeared in the prior art, such as the patent document with application number 202220636404.X, which discloses "the typhoon protection fixing device for gantry cranes provided by the utility model can support and fix the middle and bottom of the crane legs respectively through the coordinated arrangement of the first arm and the second arm, thereby moving the overall center of gravity of the crane downward, thereby improving the stability and wind resistance of the crane. After the first arm and the second arm are unfolded, the support area on both sides of the crane can be increased, thereby further improving the crane. The stability of the crane is improved, and the occurrence of undesirable phenomena such as connection breakage is eliminated, making the device as a whole safer and more reliable; the clamp can clamp and fix the crane's legs from both sides at the same time through the coordinated setting of the fixed clamp and the movable clamp, so as to improve the connection stability between the clamp and the crane, so that the device as a whole can withstand stronger typhoons; by setting a support rod, the connection and fixation of the first arm and the second arm are realized, and the structural strength of the device is further improved. The utility model has a simple structure, is easy to use, has a firm connection, is stable and reliable, can improve the typhoon resistance of the gantry crane, and ensure the safety of personnel and equipment.
