Hydraulic control system of rudder blade platform

Abstract

The invention provides a hydraulic control system of a rudder blade platform. The hydraulic control system of the rudder blade platform comprises an oil tank, a variable pump, a motor, a speed regulating valve, an overflow valve, a three-position four-way electromagnetic directional valve A, a three-position four-way electromagnetic directional valve B, a first bidirectional balance valve, a second bidirectional balance valve, a first hydraulic cylinder and a second hydraulic cylinder. The variable pump is connected with the motor. An oil inlet of the variable pump is connected with the oil tank. An oil outlet of the variable pump is connected with the speed regulating valve and the overflow valve. An oil outlet of the overflow valve is connected with the oil tank. A pressure gauge is arranged between the variable pump and the overflow valve. An outlet of the speed regulating valve is connected with the three-position four-way electromagnetic directional valve A and the three-position four-way electromagnetic directional valve B. The three-position four-way electromagnetic directional valve A is connected with the first bidirectional balance valve. The first bidirectional balance valve is connected with the first hydraulic cylinder. The three-position four-way electromagnetic directional valve B is connected with the second bidirectional balance valve, and the second bidirectional balance valve is connected with the second hydraulic cylinder. By the adoption of the hydraulic control system, labor intensity can be relieved, the requirements for movement along the X axis and movement along the Y axis of the rudder blade platform are met, and accurate positioning for rudder blade installation is achieved.

Description

technical field [0001] The invention belongs to the field of hydraulic control systems, in particular to a hydraulic control system for a rudder blade platform. Background technique [0002] Today’s domestic shipbuilding industry still adopts the traditional mechanical positioning installation process when installing rudder blades, such as installing scaffolding, and then hoisting the rudder blades to the stern by a crane, and manually using hoisting hoists, rigging, clamps and other tools to cooperate. To complete the positioning and installation of the rudder blade. This traditional process is labor-intensive, it is difficult to meet the installation accuracy and process level requirements of the rudder blade, and the cycle is long. Chinese patent CN202201128U discloses a stern work platform to solve the shortcomings of traditional technology, but this invention mainly introduces the mechanical structure of the stern work platform, and does not involve a specific hydrauli...
