Mining passenger car compartment door control system
The invention provides a mining passenger car passenger compartment door control system which comprises a hydraulic motor serving as a power element for driving a passenger compartment door to be opened and closed, a hydraulic brake used for braking the hydraulic motor, and a shuttle valve used for guaranteeing that pressure oil can enter the hydraulic brake when the hydraulic motor needs to relieve braking. The electromagnetic directional valve is used for controlling forward rotation, stop and reverse rotation of the hydraulic motor according to the control signal, the energy accumulator is used for providing high-pressure oil, the oil tank is used for returning oil, and the electric control device is used for sending a corresponding control signal to the electromagnetic directional valve according to an operation instruction and a detection signal; the hydraulic motor is in hydraulic connection with the electromagnetic directional valve, the hydraulic brake is in hydraulic connection with the electromagnetic directional valve through the shuttle valve, the electromagnetic directional valve is in hydraulic connection with the energy accumulator and the oil tank, and the electromagnetic directional valve is electrically connected with the electric control device; during use, the hydraulic motor is in transmission connection with a door spindle of a passenger compartment door. Compared with an existing pneumatic passenger compartment door control system, the pneumatic passenger compartment door control system is relatively simple in structure, low in price and lower in noise during operation.
本发明提供一种矿用客车客厢门操控系统，包括作为驱动客厢门开关动力元件的液压马达，用于对液压马达实施制动的液压制动器，用于液压马达需要解除制动时保证压力油能够进入液压制动器的梭阀，用于根据控制信号对液压马达的正转、停止和反转实施控制的电磁换向阀，用于提供高压油的蓄能器，用于回油的油箱，用于根据操作指令和检测信号向电磁换向阀发出相应控制信号的电控装置；液压马达与电磁换向阀通液连接，液压制动器通过梭阀与电磁换向阀通液连接，电磁换向阀分别与蓄能器及油箱通液连接，电磁换向阀与电控装置电连接；使用时液压马达与客厢门的门轴传动连接。本发明相对现有气动客厢门操控系统，结构相对简单、价格较低且运行时噪声更小。
