Background
The near-dam wharf of the reservoir of the hydropower station mainly undertakes daily work ships for reservoir management. The water level of the reservoir constantly changes during the daily operation of the reservoir, and the relative position relation between the ship and the wharf changes along with the change of the water level. At present, long plates (long wood plates and long steel plates), fixed ladders, ramp ways, combinations thereof and the like are mainly adopted for ships to get on and off the reservoir wharf. The annual amplitude of the water level of the medium-large reservoir can reach tens of meters, the daily amplitude can reach several meters, and when a long plate or a fixed ladder is adopted to get on or off the ship, the large-scale reservoir can be continuously used by repeatedly manually adjusting and maintaining when the daily amplitude is frequent and large. The long plate and the fixed ladder are fixed pedals (simulation pedals), the angles between the pedal treads and the horizontal plane change along with the change of water level, and the pedal is inconvenient to use and sometimes can not be used when the angle is too large. The reservoir wharf serves as a building (structure) and can get on and off ships at specific positions (in the elevation and horizontal directions). The horizontal and vertical distances between the ship and the wharf are constantly changed in a certain range along with the change of the water level, the horizontal angles between the ladder stand and the ship are constantly changed along with the change of the water level, and when the angle exceeds a certain numerical value, the ship is not favorable for getting on and off the ship, and even the ship cannot get on and off the ship. The ladder stand device is suitable for a large-water-level variable-amplitude wharf and is specially and movably suitable for boarding ships, can adapt to frequent water level changes of a reservoir wharf and huge annual amplitude of the reservoir, and meanwhile, pedals are kept to be always at (near) horizontal positions, so that the climbing ladder stand device is beneficial to getting on and off ships. The device is simple, easily installs, easy operation, and the later maintenance is simple.
Patent number CN 210000510U has announced a marine activity ladder, is applicable to and fixes with deck, ship board or other positions, including the pole setting of both sides and the footboard of setting between two pole settings, has improved marine ladder's stability and reliability.
