The embodiment of the invention discloses a car lifting jack safety control device and a car lifting jack. The safety control device of the car lifting jack comprises a signal acquisition module, a contactor, a control module and a protection module; the output end of the signal acquisition module is connected with the input end of the contactor, the output end of the contactor is connected with the signal input end of the control module, the signal output end of the control module is connected with the protection module, and the protection module is connected with a car lifting jack driving device; and the signal acquisition module is used for acquiring an alarm signal of the car lifting jack, the contactor is used for transmitting the alarm signal to the control module, the control module is used for controlling the protection module to be disconnected according to the alarm signal, and the protection module is used for forcing the car lifting jack to stop running after disconnection. The device is low in hardware cost, can independently process the alarm signal, simplifies the complexity of a safety control system compared with the prior art, improves the processing efficiency of the alarm signal, and further improves the driving operation safety of the car lifting jack.

    本发明实施例公开了一种架车机安全控制装置和架车机。该架车机安全控制装置包括信号采集模块、接触器、控制模块以及保护模块;信号采集模块的输出端与接触器的输入端连接,接触器的输出端与控制模块的信号输入端连接,控制模块的信号输出端与保护模块连接,保护模块与架车机驱动装置连接;信号采集模块用于采集架车机的报警信号,接触器用于将报警信号传输给控制模块,控制模块用于根据报警信号控制保护模块断开,保护模块用于在断开后强制架车机停止运行。本装置的硬件成本低,可以独立处理报警信号,相比于现有技术简化了安全控制系统的复杂度,提高了对报警信号的处理效率,进而提高了架车机的驾车作业安全。
