Problems solved by technology

), in order to accurately control the operation of the ship lift cabin and realize the accurate docking of the cabin, it is necessary to make frequent and precise adjustments to the openings of the water filling valve 3 and the water discharge valve 4, and small movement errors of valves with large size and high flow rate will cause The flow rate changes greatly, and it is very difficult to realize the precise control of the small flow rate during the docking process of the hydraulic ship lift directly through the large-sized valve

Embodiment 1

[0019] The operation and docking control method of the hydraulic floating ship lift of the present invention includes the precise docking of the rising operation of the ship receiving box and the precise docking of the descending operation of the ship receiving box. The precise docking process of the rising operation of the ship receiving box is as follows image 3 as shown, Figure 4 It is a schematic diagram of the accurate docking change of the ascending operation of the ship-bearing box, and the precise docking process of the descending operation of the ship-bearing box is as follows: Figure 5 as shown, Figure 6 It is a schematic diagram of the precise docking change of the lowering operation of the bearing box.

[0020] The precise docking of the rising operation of the ship-carrying box is carried out according to the following steps: (1) Open the auxiliary drain valve; (2) Determine whether the speed of the ship-carrying car meets the water outlet speed, if so, proce...

Abstract

The invention relates to a ship lifting machine operation controlling method and device, especially a hydraulic floating type ship lifting machine operation docking controlling method and device, The invention is characterized in that: an ancillary filling valve and an ancillary emptying valve are respectively connected in parallel with the main filling valve and the main emptying valve of the hydraulic floating type ship lifting machine water carriage system pipeline; the main filling valve and the main emptying valve are larger than the corresponding ancillary filling valve and ancillary emptying valve; regulating the opening of the small sized ancillary filling / emptying valve can control the ship lift chamber to enter and exit from the chamber pool; the big sized main filling / emptying valve is only opened before the ship lift chamber enters or after the ship lift chamber exits completely to increase the running speed of the ship lift chamber in air.

Description

technical field [0001] The invention relates to a method for controlling the operation of a ship lift and its device, in particular to a method for controlling the operation and docking of a hydraulic floating ship lift and its device. Background technique [0002] The hydraulic floating ship lift is a type of ship lift driven by water energy. It mainly controls the water flow in and out of the ship-bearing compartment of the ship lift and the precise docking of the ship compartment by adjusting the flow rate in the main water delivery pipeline. , Operational problems such as balance adjustment before unlocking the cabin. The traditional hydraulic floating ship lift operation docking control device such as figure 1 As shown, a single (or multiple parallel-connected) water filling valve 3 and a water discharge valve 4 are arranged on the main water delivery pipeline 2, and the opening of the single valve (water filling valve 3 and water discharge valve 4) is adjusted. Contr...
