Embodiment 1

[0033] see figure 1 , a space rope net closing device, comprising a take-up unit, a power supply control unit and a structural housing, wherein the take-up unit includes a first motor and a second motor, the first motor includes a first output shaft, and the first output shaft The first winding wheel, the first transmission gear and the first ratchet mechanism are arranged on the top; the second motor includes a second output shaft, and the second winding wheel, the second transmission gear and the second ratchet are arranged on the second output shaft mechanism, the position of the second transmission gear matches the position of the first transmission gear; the first motor and the second motor are fixed in parallel in the axial direction, the second transmission gear and the first transmission gear are both on the same end side of the transmission shaft, and the two transmission gears mesh Transmission connection, when the first motor and the second motor rotate, the two gro...

Embodiment 2

[0044] see figure 2 , this figure is a structural schematic diagram of another embodiment of the present invention, in this structure, two take-up units are fixedly arranged inside the structural housing in an axial series manner, and a reel with gears 106 is used in this embodiment , the geared reel 106 realizes the same-speed rotation between the two motors 101 through two idler gears 107 in the form of bevel gears. The embodiment of the take-up unit 100 can also realize the constant speed rotation of the two motors 101 and the transmission. When the wire is taken up, the rotation directions of the two motors 101 (referring to the motor 101 body) are the same, that is, forward rotation or reverse rotation at the same time.

[0045]This structure can save the space occupied in the width direction, and different structural arrangements can be selected according to the structural characteristics of the aircraft. The closing device provided by the present invention, by introd...

Abstract

The invention discloses a space rope net closing-up device comprising a rope taking-up unit, a power supply control unit and a structure shell. The rope taking-up unit comprises a first motor and a second motor, the first motor comprises a first output shaft, and the first output shaft is provided with a first winding wheel, a first transmission gear and a first ratchet mechanism; the second motorcomprises a second output shaft, and the second output shaft is provided with a second winding wheel, a second transmission gear and a second ratchet mechanism; the second transmission gear and the first transmission gear are matched in position and are in transmission connection, namely, the second transmission gear and the first transmission gear can provide rotating power to each other; the power supply control unit comprises a power supply and a control circuit board, the power supply provides electric energy for the first motor and the second motor, and the control circuit board is usedfor controlling the work states of the power supply and the motors; and the structure shell is arranged outside the rope taking-up unit and the power supply control unit, and a rope outlet for allowing a rope to pass through is formed in the shell corresponding to the winding wheel.

Description

technical field [0001] The invention belongs to the field of space application technology, and in particular relates to a closing device for a space rope net capture system. Background technique [0002] Space rope net is a new space control concept proposed in recent years. Compared with the traditional manipulator capture method, the rope net capture method has the advantages of large capture range, long capture distance, small impact on carrier spacecraft, and high safety. , less energy consumption and so on. [0003] In the actual use process, in order to prevent the self-rotation of the closing device, two motors are usually used to rotate in reverse, but the realization of this method in the prior art is mainly through the circuit design to precisely control the steering and speed of the motor, thus increasing the number of circuits. The complexity increases the risk of failure to a certain extent; and, because the two motors are independent of each other, when one of...
