The invention discloses a maintenance ladder for hydraulic engineering maintenance, and relates to the technical field of hydraulic engineering equipment. The device comprises vertical rods, a plurality of connecting rod pieces are installed between the two parallel vertical rods, each connecting rod piece comprises a fixed rod, a movable rod, a reset spring, an air bag and a tubular piece, a second deep groove is formed in the upper side face of each fixed rod, each air bag is placed in the corresponding second deep groove, and a telescopic movable rod is installed in a port of each second deep groove. The fixed rod and the movable rod are connected through a reset spring, a plurality of through grooves are formed in the bearing face of the movable rod and communicate with the interior of the air bag, the air bag can be provided with a telescopic tubular piece, and the movable rod in the arranged connecting rod piece moves up and down along a second deep groove. The air bag is compressed, air in the compressed air bag is discharged through the multiple through grooves formed in the bearing face of the movable rod, muddy water falling into the through grooves from a shoe sole is effectively blown out, and the friction force between the shoe sole and the movable rod is increased.
本发明公开了一种水利工程检修用维修梯，涉及水利工程设备技术领域。本发明包括立杆，两个相互平行的立杆之间安装有若干个连接杆件，连接杆件包括固定杆、活动杆、复位弹簧、气囊和管状件，固定杆的上侧面上开有深槽二，深槽二内放置有气囊，深槽二的端口内安装有可伸缩的活动杆，固定杆与活动杆之间通过复位弹簧连接，活动杆的承载面开设有若干个通槽，通槽与气囊内部连通，气囊可安装有可伸缩的管状件，设有的连接杆件中活动杆沿深槽二上下移动。本发明通过完成对气囊进行压缩，压缩后的气囊内部的空气通过活动杆的承载面开设有若干个通槽排出，有效的将鞋底落在通槽内的泥水吹出，增大鞋底与活动杆之间摩擦力。
