Embodiment 1

[0031] figure 1 For landing probe device and installation diagram, such as figure 1 As shown, this embodiment provides a helicopter landing probe device, which includes a controller 101, a motor 102, a clutch 107, a linear motion mechanism 110, a probe rod, and an elastic member 109,

[0032] The controller 101 is electrically connected to the motor 102, and the controller 101 controls the operation of the motor 102;

[0033] The motor 102 and the clutch 107, the output end of the motor 102 is connected to the clutch 107, and the clutch 107 is connected to the linear motion mechanism 110; the motor 102 drives the clutch 107 to drive the linear motion mechanism 110 in the vertical direction movement;

[0034] The probe includes a housing 103, a probe body 113 and a probe shaft 104. The housing 103 is fixed on the body structure 201, and the probe body 113 is slidably sleeved in the housing 103; The linear motion mechanism 110 passes through the through hole of the probe body 113 and ...

Embodiment 2

[0047] This embodiment provides a method for controlling a helicopter landing probe rod, using the above-mentioned helicopter landing probe rod device, and the method includes:

[0048] Adjust the power switch to the on state, the controller 101 is energized and self-checked, and feedback the fault information of the controller 101;

[0049] If the self-check shows that the controller 101 is faulty, the hand crank mechanism 108 is used to drive the linear motion mechanism 110 to move in the vertical direction;

[0050] If the self-inspection shows that the controller 101 is normal, adjust the probe rod retracting and releasing switch to the probe rod retracting position or releasing position. The motor 102 drives the clutch 107 to drive the linear motion mechanism 110 to rise or fall in the vertical direction, and the linear motion mechanism 110 The probe body 113 and the probe shaft 104 are driven to rise or fall in the vertical direction.

[0051] Further, the method includes, when ...

Embodiment 3

[0055] Combine image 3 , image 3 The control flow chart of the probe rod device for landing, combined with figure 1 , figure 2 with image 3 As shown, the actual control principle of the present invention is as follows.

[0056] A. Method of electrical control release

[0057] 1) Set the power switch on the landing control board to the "on" position, and the landing probe device is powered on for self-check. If the self-check fails, the fault information will be sent to the helicopter electromechanical management system. The helicopter electromechanical management system displays "failure of the landing probe device". At this time, the emergency manual release operation can only be used.

[0058] 2) When the power-on self-check is normal, set the "probe retracting and releasing switch" switch on the landing control board to the "release" position, and the probe will actuate to release. After the probe is released in place, the indicator light will light up. The indicator light...

Abstract

The invention belongs to a helicopter auxiliary landing system, and provides a helicopter landing probe device. The helicopter landing probe device comprises a controller 101, a motor 102, a clutch 107, a linear motion mechanism 110, a probe and an elastic part 109; the probe comprises a shell 103, a probe body 113 and a probe rod body 104, the shell 103 is fixed to a machine body structure 201, the probe body 113 is slidingly sleeved with the shell 103, the linear motion mechanism 110 penetrates through a through hole in the probe body 113, and is fixedly connected with the probe body 113, the linear motion mechanism 110 is sleeved with the elastic part 109, the elastic part 109 is located in the through hole of the probe body 113, one end of the elastic part 109 is limited in the throughhole of the probe body 113, one end of the probe rod body 104 is in contact with the other end of the elastic part 109, when the probe rod body 104 is stressed and rebounds, the elastic part 109 is compressed, the linear motion mechanism 110 is slidingly sleeved with the probe rod body 104, and the probe rod body 104 is located in the through hole of the probe body 113.

Description

Technical field [0001] The invention belongs to a helicopter landing auxiliary system, and specifically relates to a helicopter landing probe device and a control method thereof Background technique [0002] At present, the world's carrier-based helicopter landing systems mainly include the harpoon-grid landing system, the RAST pull-down system, and the ASIST carrier-based helicopter integrated tethered transport system developed on the basis of the RAST pull-down system. The ASIST carrier-based helicopter integrated mooring and transfer system integrates the functions required for helicopter landing and towing operations. All ship surface operations can be completed without the need for staff on the flight deck. [0003] The landing probe device is an important device installed on the helicopter in the ASIST carrier-borne helicopter integrated moored transport system. The landing probe device is installed under the belly of the helicopter, and the probe rod body part of the landi...
