Embodiment 1

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

[0068] 1) Carry out the mounting of the main hoisting system, the ship's chamber and the counterweight system;

[0069] 2) Carry out empty-load leveling of the vessel;

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

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

[0072] 5) Mark the water level in the ship-holding compartment: the water level in the ship-holding compartment is the water level at the balance critical point of the vertical ship lift.

[0073] First, hang the main hoisting system with the counterweight system and the ship-bearing box res...

Embodiment 2

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

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

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

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

[0102] Adjust the leveling tool so that the counterweight device remains horizontal after being hoisted.

[0103] The adjusting screw can be selected as the leveling tool, and the elongation of the adjusting screw can be adjusted to the middle position of the screw stroke to provide a margin for subsequent adjustments, and the steel wire rope can be fixedly connected with the leveling tool to realize the fixing of the balance weight system and the main lifting system Connect, then you can adjust the self-level ad...

Abstract

The invention relates to the technical field of ship lifts, in particular to a method for determining the balance critical point water level of a vertical ship lift. The method comprises the following steps that (1) hanging a main lifting system, a ship reception chamber and a balance weight system; (2) carrying out no-load leveling on the ship reception chamber; (3) carrying out water injection operation, wherein water is injected into the ship reception chamber till the total weight of the ship reception chamber and the total weight of the balance weight system are balanced; (4) carrying out static leveling on the ship reception chamber and a balance weight system; and 5) marking the water level in the ship reception chamber, wherein the water level in the ship reception chamber is the balance critical point water level of the vertical ship lift. According to the scheme, the main lifting system of the vertical ship lift is efficiently and conveniently hung and connected with the ship reception chamber and the balance weight system, and then the problem of determining the critical water level when the weight of the ship reception chamber and the weight of the balance weight system are balanced is solved.

Description

technical field [0001] 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. Background technique [0002] During the installation and tensioning process of the balance weight of the ship lift and the steel wire rope of the ship-holding box, the weight balance of the ship-holding 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 ship's pontoon, so as to finally find the critical water level when the weights on both sides are balanced. [0003] Chinese invention patent, publication (announcement) number: CN201610473555.7; publication date: 2016-11-09; discloses a test method for the water-filled cabin of the ship lift to test the self-locking reliability of the safety mechan...
