Abstract

The invention provides a manual and automatic integrated engagement and disengagement type switching safe operation mechanism. The mechanism comprises a split nut, a lead screw, a handle, a spring anda pneumatic mechanism. The split nut is horizontally arranged and provided with a tooth groove. The lead screw is vertical to the split nut, the handle is connected with the split nut, and the splitnut moves close to or away from the lead screw in the horizontal direction under rotation regulation of the handle. The pneumatic mechanism comprises a microprocessor. A relay, an NB-IOT module and alithium battery are connected to the microprocessor, the NB-IOT module is externally connected with an NB-IOT base station, and the NB-IOT base station is connected with a mobile terminal through theInternet. The mechanism has the advantages of being simple in structure, safe in switching and easy to operate and achieving remote real-time control manual and automatic integrated engagement and disengagement type switching.

Description

technical field [0001] The invention belongs to the technical field of clutch operating devices, and in particular relates to a safety operating mechanism for hand-automatic clutch switching. Background technique [0002] Pneumatic actuators are necessary devices for opening and closing or regulating valves (such as gate valves, globe valves, etc.) in pipeline technology. However, if the operating system of the pneumatic device is abnormal or the gas source fails, the valve cannot be opened and closed in time, which will affect the construction. At the same time, it brings certain risks to the operation. [0003] A patent for a safety operating mechanism for manual-automatic clutch switching (publication number CN206175780U) discloses a manual-automatic integrated clutch switching safety operating mechanism. The opening and closing control of wheel valves is innovative. The safety operating mechanism includes opening and closing nuts, lead screws, handles, springs and pneum...
