Problems solved by technology

[0003]However, traditional common rotorcraft generally place the drive system at the joints, which makes the inertia of the moving arm part too large, and the drive system of the upper level becomes the load of the lower level. This leads to high energy consumption and small load capacity. After the operating device is added, the load capacity is further reduced, and disturbances such as center of gravity offset will occur during the movement of the operating device, resulting in a decrease in the stability of the aircraft.
In addition, due to the limitation of battery technology, the battery capacity is low, and the single flight time of most rotorcraft is relatively short, making ordinary flying manipulators unable to carry out long-term high-altitude operations

Embodiment Construction

[0035] like figure 2 As shown in the figure, a tethered flying manipulator based on cable tension control of the present invention includes an aircraft 1, a ground station, a manipulator 2, a rope drive device, and a mooring control device 3. The aircraft 1 adopts a multi-rotor aircraft, and the manipulator 2 and the mooring control device 3 are respectively arranged on both sides of the center of the bottom of the multi-rotor aircraft 1. The starting position of the mechanical arm 2 is a certain distance away from the center of the bottom of the multi-rotor aircraft 1, and is located on the same side of the aerial working position, which can effectively Increase the maximum extension distance of the flying manipulator to better meet aerial operations. In order to balance the torque generated by the manipulator 2 by the mooring cable 31 , the interface between the mooring cable 31 and the multi-rotor aircraft 1 is arranged on the opposite side of the manipulator 2 .

Abstract

The invention discloses a mooring flight mechanical arm based on mooring rope tension control, which comprises an aircraft, a ground station, a mechanical arm, a rope driving device and a mooring control device, the mechanical arm and the mooring control device are respectively arranged on two sides of the center of the bottom of the aircraft, and the mooring control device comprises a mooring rope and a ground moving platform. The power supply part of the mooring flight mechanical arm is arranged in the ground moving platform, and the ground moving platform supplies power to the aircraft and the rope driving device through the mooring rope. According to the mooring flight mechanical arm, the large-capacity battery is arranged on the ground moving platform, power is supplied to the mooring flight mechanical arm through the mooring cable, uninterrupted power supply to the mooring flight mechanical arm can be achieved, the aerial operation time is prolonged, meanwhile, no large-capacity battery needs to be used on an aircraft, the mass of an aircraft body can be reduced, and the flight quality is improved.

Description

technical field [0001] The invention relates to aerial operation of a flying manipulator, in particular to a mooring flying manipulator based on cable tension control and a cable tension control method thereof. Background technique [0002] In recent years, due to the rapid development of aircraft technology, UAVs have been widely used. However, most of the current applications and researches of UAVs are based on observation and patrol, and lack interaction with the environment. Faced with the increasing demand for aerial operations, an aerial manipulator based on rotorcraft is proposed. Combining the aerial motion control, hovering performance and operability of the manipulator of the rotorcraft, a rotorcraft manipulator is formed to realize aerial operations. [0003] However, traditional ordinary rotorcraft generally place the drive system at the joints, which makes the inertia of the moving arm part too large, and the upper-stage drive system becomes the load of the ne...
