Electro-hydraulic control system for parking brake of walking of milling machine
The invention discloses an electro-hydraulic control system for parking brake of walking of a milling machine. The electro-hydraulic control system comprises a display, a controller, a pressure sensor, walking pump electric servo valves, a first electromagnetic reversing valve and a second electromagnetic reversing valve. The input end of the controller is connected with the pressure sensor and the walking pump electric servo valves a and b, the output end of the controller is connected with the first electromagnetic reversing valve Y2 and the second electromagnetic reversing valve Y1, and thecommunication end of the controller is connected with the display. The controller reads and analyzes pressure signals collected by the pressure sensor and current signals of the walking pump electricservo valve a and the walking pump electric servo valve b, feeds back the pressure signals to the display, and finally controls the first electromagnetic reversing valve and the second electromagnetic reversing valve to act. The electro-hydraulic control system not only can realize parking brake recovery and parking brake release of walking of the milling machine, but also can prevent the millingmachine from working for a long time in a half-brake state to influence the service life of elements such as a speed reducer.
本发明公开了一种铣刨机行走驻车制动电液控制系统，包括显示器、控制器、压力传感器、行走泵电伺服阀、第一电磁换向阀和第二电磁换向阀；控制器的输入端分别与压力传感器和行走泵电伺服阀a、b连接，控制器的输出端分别与第一电磁换向阀Y2和第二电磁换向阀Y1连接，控制器的通讯端与显示器连接；控制器对压力传感器采集的压力信号和行走泵电伺服阀a、b的电流信号进行读取与分析，并将所述压力信号反馈至显示器，最终控制第一电磁换向阀和第二电磁换向阀动作；该电液控制系统不仅能实现铣刨机行走驻车制动恢复和驻车制动解除，还能够防止铣刨机在半制动状态下长时间工作，影响减速机等元件寿命。
