[0038] 5. The traction system braking device provided by the invention for the ship passing through the ship lift has a hydraulic buffer braking device and a cable braking device in addition to the braking of the electric push wheel of the traction system itself. Compared with the self-navigation ship having only its own braking device, the invention greatly improves the safety of the ship passing through the ship lift.

[0068] According to another aspect of the application, a method for towing a ship by a ship lift is also provided, comprising the following steps:

[0069] S1 The ship 10 to be lifted is moored. More specifically, according to the ship scheduling plan through the ship lift, the operator guides the ship to be lifted to navigate to the upstream or downstream mooring dolphin 12 through the ship lift scheduling system.

[0070] S2 The electric thruster 1 near the ship 10 is started, and the electric thruster 1 is driven to move to the ship 10 according to the navigation data and ship data of the ship 10, and the height of the connecting male head 501 and the connecting female head 502 is adjusted to enable the connecting male head 501 and the connecting female head 502 to be quickly connected. More specifically, after the ship 10 to be lifted is moored and stopped at the upstream or downstream mooring dolphin 12 of the ship lift, the operator of the ship lift starts the upstream or downstream electric thruster 1 through the remote centralized control system 103 and issues the command of the downlink or uplink ship traction, and the navigation control system 104 controls the upstream or downstream electric thruster 1 to navigate to the upstream or downstream ship 10 to be lifted, and adjusts the height of the connecting frame 5011 of the electric thruster and the ship quick connection device 5 according to the information of the ship 10 to be lifted obtained from the ship database 11. After the electric thruster 1 navigates to the ship 10 to be lifted and the height of the connecting frame 5011 is adjusted, the electric thruster 1 and the ship 10 are quickly connected.

[0071] S3 After the electric thruster 1 and the ship 10 are connected, the ship 10 is unmoored, and after the ship 10 is unmoored, the electric thruster 1 drives the ship 10 to enter the ship lift module 6 according to the preset route.

[0072] S4 When the ship 10 navigates to the designated position of the ship compartment, the ship is decelerated and braked through the braking system 3. More specifically, when the ship 10 navigates to the upstream or downstream end of the ship transverse center line, the electric thruster 1 starts to brake and decelerate, and drives the ship 10 to enter the ship compartment to start to decelerate; when the ship 10 navigates to the upstream or downstream end of the ship tail end face, the steel wire rope 3-104 cable ring of the hydraulic buffer brake device 3-1 is hung on the tail bollard of the ship 10. In this step, the load limiting connector 3-105 of the braking system 3 can bear a maximum tension of T, and when the braking tension exceeds T, the steel wire rope 3-104 connected through the load limiting connector 3-105 is disconnected from the piston rod of the buffer oil cylinder 3-101, the hydraulic buffer brake device 3-1 is disabled, and when the ship is out of control, the cable thrown on the ship is hung on the large-tonnage bollard arranged in the middle of the two sides of the ship compartment to brake.

The out-of-chamber ship 10 reaches the downstream or upstream berthing pier 12 to complete the deceleration and stop, and the electric thruster 1 is disconnected from the ship 10.

[0087] Step 7): The ship 10 entering the chamber decelerates and stops, and after the ship chamber is moored, the steel wire rope 3-104 cable ring is removed from the ship 10 tail, the buffer oil cylinder 3-101 drives the steel wire rope 3-104 to retract, and the electric push wheel 1 is disconnected with the ship 10.

[0088] Step 8): After the electric push wheel 1 is disconnected with the ship 10, the ship hoist operator issues a command to return the downstream electric push wheel 1 to the downstream charging dock 402, the electric push wheel 1 sails to the downstream charging dock 402 and charges the power storage battery pack 102 of the electric push wheel 1.

[0089] Step 9): After the electric push wheel 1 exits the ship chamber, the ship chamber starts to be disconnected with the downstream lock head, and starts to go up and be connected with the upstream lock head.
