The application relates to a dam maintenance ladder, which includes a rotating shaft, a mounting part sleeved on the rotating shaft, several climbing poles connected to the mounting part, and a power source for driving the rotating shaft to rotate. An accommodation groove is provided on the facing surface of the dam, the accommodation groove is arranged parallel to the height direction of the dam, the rotating shaft is rotationally connected with the mounting part, the rotating shaft is coaxially rotating and connected in the containing groove, and one side of the mounting part is provided with The installation plane is arranged parallel to the length direction of the installation part, the climbing rod is fixedly connected to the installation plane, the tank side wall of the accommodation groove, the groove bottom of the accommodation groove and the installation plane form a storage space. A drainpipe for discharging water entering the storage space is also provided on the tank wall of the receiving tank; a sealing member for separating the storage space from water is also provided on the outer wall of the installation part. The application has the effect of improving the service life of the climbing pole.
Description
technical field [0001] The present application relates to the technical field of dams, in particular to a dam maintenance ladder. Background technique [0002] At present, concrete is often used as a material for reservoir dams, and in daily use, maintenance and protection are usually carried out, such as repairing of concrete cracks and leakage treatment. The maintenance ladder is a facility used to facilitate maintenance personnel to dive down from the water surface of the dam. [0003] In view of the above-mentioned related technologies, the inventor believes that because the maintenance ladder of the dam is usually soaked in water, it is easy to cause the maintenance ladder to rust and fall off, thereby reducing the service life of the maintenance ladder. Contents of the invention [0004] In order to ensure the service life of the maintenance ladder, the application provides a dam maintenance ladder. [0005] A kind of dam maintenance ladder provided by the applicat...
