Embodiment 1

[0067] combined with figure 1 , the present embodiment proposes a method for determining the water level at the critical point of vertical ship lift equilibrium, including the following steps:

[0068] 1) Carry out the installation of the main hoisting system, the carrying box and the counterweight system;

[0069] 2) Carry out no-load leveling of the vessel;

[0070] 3) Carry out the water injection operation of the ship-carrying compartment: inject water into the vessel-carrying compartment until the total weight of the vessel-carrying compartment and the total weight of the counterweight system reach a balance;

[0071] 4) Carry out the static leveling of the carrying box and the counterweight system;

[0072] 5) Mark the water level in the vessel: the water level in the vessel is the water level at the critical point of vertical ship lift equilibrium.

[0073] First, the main hoisting system is mounted with the counterweight system and the carrier box respectively, so tha...

Embodiment 2

[0098] This embodiment proposes a method for determining the water level at the critical point of vertical ship lift equilibrium, which can be improved as follows on the basis of Embodiment 1: Step 1-2) includes:

[0099] The mounting of the counterweight system and the main lifting system includes:

[0100] Adjust the leveling tool on the upper side of the counterweight device to the middle of the stroke;

[0101] Fix the wire rope to the leveling tool;

[0102] Adjust the leveling tool so that the counterweight remains level after being lifted.

[0103] The adjusting screw can be selected as the leveling tool, and the elongation of the adjusting screw is adjusted to the middle position of the screw stroke to provide a margin for subsequent adjustment, and the wire rope and the leveling tool can be fixedly connected to realize the fixation of the balance weight system and the main lifting system. After connection, the self-level adjustment of the counterweight device when i...

Abstract

The invention relates to the technical field of ship lifts, in particular to a method for determining the water level of a critical equilibrium point of a vertical ship lift. It includes the following steps: 1) mount the main hoisting system, the ship-holding box and the counterweight system; 2) carry out the empty-load leveling of the ship-holding box; The total weight of the box and the total weight of the counterweight system are balanced; 4) Perform static leveling of the ship-holding box and the counterweight system; 5) Mark the water level in the ship-holding box: the water level in the ship-holding box is critical for the balance of the vertical ship lift Point the water level. This solution efficiently and conveniently realizes the mounting and connection of the main hoisting system of the vertical ship lift with the ship-holding box and the counterweight system, and then solves the problem of determining the critical water level when the ship-holding box and the counterweight system are balanced.

Description

technical field [0001] The invention relates to the technical field of ship lifts, in particular to a method for determining a water level at a critical point of equilibrium of a vertical ship lift. Background technique [0002] In the process of the balance weight of the ship lift and the wire rope hanging and tensioning of the ship carrying box, the weight leveling of the ship carrying box and the balance weight is one of the key links in the on-site installation and commissioning of the ship lift. It is a technical difficulty to realize the hanging and tensioning of the steel wire ropes of the balance weight and the carrier, so as to finally find the critical water level when the weights on both sides are balanced. [0003] Chinese invention patent, publication (announcement) No.: CN201610473555.7; publication date: 2016-11-09; discloses a test method for the full water condition of the ship lift cabin to test the self-locking reliability and safety of the safety mechanis...
