Problems solved by technology
[0004] The structure of the ship lift has the characteristics of large scale, huge load, high requirements for structural deformation and high safety and reliability for the operation of mechanical equipment, but the stiffness of the ship lift tower structure in the direction perpendicular to the river is lower than that along the river. The direction is much smaller. Under the seismic load perpendicular to the direction of the river, the structure is prone to large displacement and stress, which is easy to damage the structural strength and working stability of the ship lift, and it is difficult to guarantee the safety.

The invention relates to a balance weight device of a vertical ship lift with a function of tuning and damping, which belongs to the technical field of ship lifts; it includes a tower column, a ship bearing box, a balance weight, a driving connection structure and a tuning and damping mechanism; the driving The connection structure includes a steel wire rope, a steel wire support arranged at the top of the tower column, a reel arranged at the top of the tower column, and a movable pulley arranged above the balance weight to connect the balance weight. One end of the steel wire rope is fixedly connected to the steel wire support, and the other end of the steel wire rope One end is first wound around the movable pulley, then wound around the reel in an S-shape, and finally connected to the adjacent end on the ship-bearing box; the invention provides a vertical ship lift balance weight device with tuning and shock absorption function, which can balance The weight of the ship-bearing box and the counterweight effectively transmits the power to drive the ship lift up and down, and can restrain the vibration energy of the dissipated tower, prevent the counterweight from shaking too much, and ensure the structural strength and working stability.
Description
technical field [0001] The invention relates to a balance weight device of a vertical ship lift with the function of tuning and damping, and belongs to the technical field of ship lifts. Background technique [0002] my country is the country with the most abundant water energy resources in the world. In order to comprehensively utilize water energy resources, it is necessary to build water conservancy projects to store river water for the purpose of flood control, power generation, shipping, irrigation, breeding, etc. Concentrated water level drops will be formed after the construction of water conservancy projects , in order to keep the upstream and downstream of the channel unblocked and help ships overcome the water level difference between the upstream and downstream, it is necessary to build corresponding navigable structures. Ship locks and ship lifts are two common types of navigable structures; It has the advantages of small technical conditions and fast operation spe...
