Description
Technical Field
[0001] The utility model relates to the technical field of ship lock engineering, in particular to a ship lock miter gate working bridge. Background Art
[0002] A ship lock is a navigation structure for ships to overcome concentrated water level differences. It is the most commonly used navigation structure in water conservancy and water transport projects. The main structure of the ship lock consists of upper and lower lockheads, lock chambers, water delivery systems, and gate valves. When a ship is going upstream, the water level in the lock chamber is discharged to the downstream water level, the lower gate is opened, the ship enters the lock chamber, the lower gate is closed, water is poured from the upstream into the lock chamber to the upstream water level, the upper gate is opened, the ship leaves the lock chamber and enters the upstream channel. The opposite is true for ships going downstream.
[0003] When constructing a ship lock project, a pedestrian bridge is usually set up on the top of the miter gate to facilitate the passage of people on both sides of the ship lock and the maintenance of the miter gate. In the prior art, the connection between the pedestrian bridge on the top of the ship lock miter gate and the cover plate of the inspection area of the top pivot of the gate head is usually achieved by dislocation of height difference (the pedestrian bridge on the top of the ship lock miter gate is set on the top surface of the miter gate and the bridge panel is set above the cover plate of the inspection area of the top pivot of the gate head) to solve the problem of space transformation caused by the opening and closing of the miter gate. When the miter gate is opened, the connection and closure effect between the gate head and the top passage of the miter gate is poor, and it is necessary to pull the iron chain at the entrance and exit position of the gate head to close the gate head guardrail. When the miter gate is in operation (opening or closing process), there is always a gap between the entrance and exit facing the air and the water. The iron chain is also easy to get tangled during operation, which poses certain safety hazards and also affects the aesthetic effect of the entire lock area.
