Embodiment Construction
[0032] Such as figure 1 , figure 2 , a safety protection device applied to the ship-bearing compartment of a fully balanced wire rope winch vertical ship lift. The safety protection device is arranged on the balance weight of the ship-bearing compartment and can exert pressure on the guide rail 1 of the balance weight. The guide wheel 2 is in contact with the guide rail 1, and the safety protection device includes a motor 31, a screw rod 32, a spring 33, a friction plate 34, a push rod 36, a guide rod 37, a nut plate 38, and a frame;
[0033] The frame includes a panel with a side panel, an installation rear panel 39, a fixing member 311, and an installation front panel 313. The installation rear panel 39 and the installation front panel 313 are respectively fixed on the corresponding side panels of the panel, and the fixing member 311 is fixed on the installation rear panel 39 on,
[0034] The screw rod 32 is movably fixed on the frame, the guide rod 37 is fixed on the fra...

The invention relates to a safety protection device for a ship reception chamber of a full balanced steel wire rope hoisting vertical ship lift and a lifting protection method. The safety protection device is additionally arranged on a balancing weight of the ship reception chamber, pressure is applied to a guide rail of the balancing weight by the safety protection device to adjust the friction force between the balancing weight and the guide rail, and when the ship reception chamber leaks, the balance of the balancing weight and the ship reception chamber is achieved by friction force; when the ship reception chamber is in high wind, the friction force is increased to increase the weight of the balancing weight, so as to resist the variation of the swing gravity of the ship reception chamber, ensure that the ship reception chamber can stop safely at any time and guarantee the safe operation of the vertical ship lift.
Description
technical field [0001] The invention belongs to the field of safety protection of a ship lift, and is used for preventing safety accidents caused by imbalance during the operation of the ship lift and improving the operation safety of the ship lift. Background technique [0002] There are generally two types of lifting drive mechanisms for vertical ship lifts. One is the German Lüneburg-style gear tooth ladder climbing and large screw safety protection device; the other is the wire rope hoisting type widely used in Ströby, Belgium and China. [0003] Generally speaking, during the operation of the ship lift, the main reasons for the unbalance of the ship bearing compartment are mainly concentrated in sudden water leakage accidents, strong winds, heavy rains, etc. For fully balanced boat lifts, excessive loss of water in the cabin, loss of control, or excessive swing in strong winds will lead to damage to the balance system. The gravity of the counterweight will pull the ca...
