Single-side fast opening and closing control system of large double-top-cover mechanism of launching platform

Abstract

A single-side fast opening and closing control system of a large double-top-cover mechanism of a launching platform comprises a front top cover, a rear top cover, a front top cover hydraulic oil cylinder for driving the front top cover to move, and a rear top cover hydraulic oil cylinder for driving the rear top cover to move. Hydraulic pipelines connected with the front top cover hydraulic oil cylinder and the rear top cover hydraulic oil cylinder are respectively provided with a proportional flow valve, a proportional overflow valve and an electromagnetic directional valve. A valve micro-processing controller is connected with the proportional flow valves, the proportional overflow valves and the electromagnetic directional valves. A main controller is connected with the valve micro-processing controller and photoelectric encoders through a CAN bus. The photoelectric encoders are arranged on a front top cover mechanism and a rear top cover mechanism respectively. Double-loop individual control is performed on the front top cover and the rear top cover, and the flow of a front top cover loop and the flow of a rear top cover loop are controlled through the proportional flow valves respectively; the movement speed of the front top cover and the movement speed of the rear top cover are kept consistent, the front top cover mechanism and the rear top cover mechanism do not interfere with each other, damage to the front top cover mechanism and the rear top cover mechanism is prevented, the top covers are fast opened and closed in a double top cover linkage mode when the launching platform carries out movements of the top cover mechanism, and the launching preparation time is shortened.

Description

technical field [0001] The invention relates to a motion control system, in particular to a single-side rapid switch control system for a large-scale double top cover mechanism of a launching platform. Background technique [0002] With the continuous development of information technology, the requirements for the launch preparation time of the launch platform are getting higher and higher. Short launch preparation time, strong environmental adaptability, and high degree of intelligence have become important development directions for launch platforms in the future. [0003] The double top cover of the launch platform is a large mechanical structure with large mass and large inertia. When the top cover is opened and closed to the cut-off angle, there will be relatively violent shaking, which will affect the normal operation of the launch platform. [0004] Existing launch platforms use an open-loop method to implement the top cover mechanism action, and the front and rear to...

Problems solved by technology

[0003] The double top cover of the launch platform is a large mechanical structure with large mass and large inertia. When the top cover is opened and closed to the cut-off angle, there will be relatively severe shaking, which will affect the normal operation of the launch platform.

[0004] Existing launch platforms use an open-loop method to implement the top cover mechanism action, and the front and rear top cover action speeds are inconsistent, resulting in mutual interference between the front and rear top cover mechanisms, resulting in damage to the front and rear top cover mechanisms, and the top cover The opening and closing speed is slow , extending the launch preparation time
