Description

Technical Field

[0001] The invention relates to the technical field of ship controllers, in particular to a ship double-handle controller. Background Art

[0002] The main oil production machine manipulator on board is the operating component of the marine oil production machine. The control system remotely controls the manipulator to issue control commands. Currently, the common main diesel engine remote controllers generally use a joystick to drive the potentiometer shaft to rotate. The potentiometer is connected to the single-chip microcomputer or PLC system through a circuit board. By changing the operating potentiometer to different gears, different signals are sent to the single-chip microcomputer or PLC. When the single-chip microcomputer or PLC receives the signal, it sends a signal to the actuator after logical operation to drive and verify that the actuator completes the command issued by the manipulator.

[0003] Existing handle controllers are usually double-handle controllers, and can be adjusted by a single handle or by both handles.

[0004] When the current dual-handle controller adjusts the throttle engine together, the distance between the two sets of handles is small, so when one handle is turned, it is easy to touch the other handle, making it easy for the other manipulator handle to turn, causing control problems.

At this time, the adjusting button 5 is pressed, and the adjusting button 5 drives the traction rope 19 to tighten, thereby pulling the storage limit block 15 into the second limit holding slot 24, until the telescopic limit block 22 passes through the uppermost set of telescopic limit slots 6 to fix the gear adjustment handle 4, then one set of gear adjustment handles 4 extends outwards, and the heights of the grips of the two sets of gear adjustment handles 4 are inconsistent. Therefore, when the two sets of gear adjustment handles 4 are operated, the two sets of gear adjustment handles 4 will not interfere with each other, thereby improving the service life of the gear adjustment handles 4.
