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

Embodiment Construction

[0018] The present invention is described in detail below with reference to accompanying drawing and embodiment:

[0019] In the accompanying drawings, the front top cover is referred to as the front cover for short; the rear top cover is referred to as the back cover for short.

[0020] attached Figure 1-5 It can be seen that a large-scale double roof mechanism unilateral fast switch control system on the launch platform includes a front roof and a rear roof, and a front roof hydraulic cylinder and a rear roof hydraulic cylinder that drive the movement of the front roof and the rear roof. The top cover hydraulic cylinder and the rear top cover hydraulic cylinder are respectively connected to the hydraulic pump station through hydraulic pipelines, and the hydraulic pipelines connected to the front top cover hydraulic cylinder and the rear top cover hydraulic cylinder are respectively provided with proportional flow valves and proportional overflow valves. Valve and electroma...

Abstract

A unilateral rapid switch control system for a large-scale double roof mechanism on a launch platform, including front and rear roofs, front and rear roof hydraulic cylinders that drive the movement of the front and rear roofs, and hydraulic pipelines connected to the front and rear roof hydraulic cylinders There are proportional flow valves, proportional overflow valves and electromagnetic reversing valves. The controller is connected with the photoelectric encoder; the photoelectric encoder is arranged on the front and rear top cover mechanisms. In the present invention, the dual circuits of the front and rear top covers are separately controlled, and the flow rate of the front top cover circuit and the rear top cover circuit are respectively controlled by using a proportional flow valve; When the launch platform performs the action of the top cover mechanism, the double top cover linkage method is used to realize the quick switch of the top cover and shorten the launch preparation time.

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...
