The invention relates to the technical field of engineering machinery, in particular to a control device, a loading operation mechanism and a crane. The control device is applied to the loading operation mechanism of the crane. The boarding operation mechanism comprises an operation handle and an ignition switch. The control device comprises a pressure detection module and a control module. Wherein the control module is electrically connected with an enabling switch of the operating handle, and the state of the operating handle can be obtained by judging whether the enabling switch is closed or not; the control module is electrically connected with the pressure detection module and can obtain the pressure, detected by the pressure detection module, of the control oil way or obtain the state of the pressure detection module. And the control module is also electrically connected with a flameout gear of the ignition switch, and can switch on the flameout gear of the ignition switch and control the engine to flameout under the conditions that the operation handle is in a non-operation state and the pressure of the control oil way is greater than a pressure threshold value or the pressure detection module is in a conduction state, so that accidents caused by misoperation of the crane are avoided.

    本公开涉及工程机械技术领域,具体地,涉及一种控制装置、上车操作机构及起重机。该控制装置应用于起重机的上车操作机构。该上车操作机构包括:操作手柄和点火开关。该控制装置包括:压力检测模块和控制模块。其中,控制模块与操作手柄的使能开关电连接,能通过使能开关是否闭合,获得操作手柄的状态;控制模块与压力检测模块电连接,能获得压力检测模块检测的控制油路的压力或获得压力检测模块的状态;控制模块还与点火开关的熄火挡位电连接,能在操作手柄处于无操作状态,且控制油路的压力大于压力阈值或压力检测模块处于导通状态的情况下,接通点火开关的熄火挡位,控制发送机熄火,从而避免起重机误动作引起事故。
