A multi-cylinder cooperative vertical hydraulic system

Abstract

The invention provides a multi-cylinder synergistic erecting hydraulic system. The multi-cylinder synergistic erecting hydraulic system comprises an erecting loop, a launcher loop and a locking loop.The multi-cylinder synergistic erecting hydraulic system is composed of a hydraulic source (1), a reversing valve bank (2), a rodless cavity valve bank (3), a rod cavity valve bank (4), a launcher valve bank (5), an erecting oil cylinder (6), a locking oil cylinder (7) and a launcher oil cylinder (8). The multi-cylinder synergistic erecting hydraulic system is characterized in that double-acting hydraulic cylinders are adopted for an erecting mechanism and a launcher correspondingly and used for achieving separate motion of the erecting mechanism and the launcher; meanwhile, rapid linkage erecting and releveling of the erecting mechanism and the launcher can be achieved, the erecting speed is increased by 20% compared with the former practice, and the releveling speed can be increased by 30%; launching preparation time is shortened; safety of the linkage erecting process is improved; the chattering phenomenon generated in the oil cylinder grade changing process is eliminated; and steadiness of the erecting process is improved.

Description

technical field [0001] The invention belongs to the technical field of erection of large launching devices, and in particular relates to a multi-cylinder cooperative erection hydraulic system. Background technique [0002] Lifting the launching device from the horizontal state to the vertical state within a certain period of time is the core task that the hydraulic system needs to complete. It not only determines the maximum power required by the hydraulic system, but also reflects the key technology of the system. [0003] In the past, double-acting hydraulic cylinders were generally used to drive the erecting mechanism, and single-acting plunger cylinders were used to drive the launching device. When the launching device was erected, it was first lowered to the position by the gravity of the launching device, and then the missile was erected by the vertical cylinder. In place, this method has more movements, and the erection process takes a long time; if the linkage erecti...

Problems solved by technology

[0003] In the past, double-acting hydraulic cylinders were generally used to drive the erecting mechanism, and single-acting plunger cylinders were used to drive the launching device. When the launching device was erected, it was first lowered to the position by the gravity of the launching device, and then the missile was erected by the vertical cylinder. In place, this method has more movements, and the erection process takes a long time; if the linkage erection method is adopted, the movement speed and force of the launching device cannot be controlled, and it can only passively adapt to the movement speed of the erection mechanism, giving the weapon system Security poses hidden dangers
