And because the maintenance positions of some equipment are relatively high, a maintenance platform needs to be set up to meet the maintenance requirements, which results in a low overall space utilization rate.

[0003] In the prior art, a marine passage step (authorized publication number CN215323166U) is disclosed in a Chinese patent. In this patented technology, a plurality of tread plates are arranged on a bracket. Therefore, after a fixing seat is installed on a ship, when in need of use, the bracket can be rotated and unfolded from the fixing seat, and the stoppers thereon limit the rotation angle of the bracket and play a role in supporting the bracket. Thus, maintenance personnel can stand on the tread plates to maintain equipment with a relatively high installation position, playing an auxiliary maintenance role.

[0004] However, the tread plates in the above application document are fixedly connected to the fixing seat, which makes it inconvenient to install and replace the tread plates when they are damaged, thereby reducing the service life of the overall device. Therefore, an installation structure of a passage step is provided to solve the problems raised in the above background art. Content of the Utility Model
