Hydraulic control system and method for telescopic screed of paver and paver
The invention discloses a hydraulic control system and method for a telescopic screed of a paver and the paver. The system comprises a hydraulic valve block, a first electromagnetic reversing valve, a second electromagnetic reversing valve, a first hydraulic oil cylinder, a second hydraulic oil cylinder and a control device. The hydraulic oil cylinder I is used for driving the first telescopic section screed plate to stretch/retract in the width direction relative to the basic section screed plate; the hydraulic oil cylinder II is used for driving the second telescopic section screed plate to stretch/retract in the width direction relative to the first telescopic section screed plate; and the control device is used for controlling the hydraulic oil cylinder I and the hydraulic oil cylinder II to extend/retract simultaneously or respectively through the hydraulic valve block, the electromagnetic directional valve I and the electromagnetic directional valve II according to a received control instruction. According to the invention, different ironing plates can be respectively or simultaneously controlled to stretch and retract, and the consistent stretching and retracting speed can be ensured.
本发明公开了一种摊铺机伸缩熨平板的液压控制系统、方法及摊铺机，系统包括：液压阀块、电磁换向阀一、电磁换向阀二、液压油缸一、液压油缸二和控制装置；所述液压油缸一用于驱动第一伸缩段熨平板相对于基础段熨平板在宽度方向上进行伸/缩；所述液压油缸二用于驱动第二伸缩段熨平板相对于第一伸缩段熨平板在宽度方向上进行伸/缩；所述控制装置用于根据接收到的控制指令，通过液压阀块、电磁换向阀一和电磁换向阀二控制液压油缸一、液压油缸二同时或分别伸出/缩回。本发明能分别或同时控制不同的熨平板进行伸缩动作，并且能保证伸缩速度的一致。
