Example Embodiment

[0042] Example 1

[0043] Such as figure 1 , A hoist, composed of a reel, a motor, and a brake. The brake adopts the multi-disc brake disc and braking force regulator of the A320 passenger plane. The length of the drum is 3 meters, the diameter is 3 meters, and the diameter of the multi-disc brake disc is 0.8 meters. The multi-disc brake disc is installed in the reel, and the axis of the brake is collinear with the axis of the reel, so that the braking force is directly transmitted to the reel, reducing the structural weight.

[0044] A tension sensor (3) and a wireless communication device are installed at the end of the cable (2), and a wireless communication device is also installed on the hoist. If the pulling force of the cable end towing the spacecraft is deviated, it will be sent to the hoisting machine by radio, and the braking force regulator adjusts the pressure of the hydraulic components, so that the braking force of the hoisting machine can be adjusted to ensure the ...

[0045] Example 2

[0046] A hoist, composed of a reel, a motor, and a brake. The web 6 of the drum of the hoist is connected to the force transmission tube 2 of a multi-disc brake disc, such as figure 2 Shown. An electric eddy current retarder is installed on the inner wall of the drum. Each drum is equipped with an eddy current retarder, which can also function as a brake. The excitation coil of the eddy current retarder is installed on the rotor, and the rotor is installed on the drum. The stator is installed on the shaft of the reel. In the composition structure of the stator, the weight of lithium accounts for 60%. The coil of the rotor is excited to generate a changing magnetic field, which makes the stator generate eddy current and heat, and the heat is contained by the stator. Lithium has a large specific heat capacity, less temperature rise, and saves structural weight.

[0047] The advantage of the eddy current retarder is that the stator and rotor are non-contact, a...

[0048] Example 3

[0049] Such as image 3 As shown, a transfer cable system is composed of two counterweights, a central station 14, two counterweight ropes 18, a main rope, three winches 1, and a battery. The two counterweights are called A counterweight 15 and B counterweight 16, respectively. A counterweight is on one side of the central station, and B counterweight 16 is on the other side of the central station's symmetry. A counterweight rope 18 connects the A counterweight 15 and the central station 14, and another counterweight rope 18 connects the B counterweight 16 and the central station. The main rope is used to connect the spacecraft and the central station. The main rope and A counterweight are on the same side. A counterweight is equipped with a pulley. The main rope passes through the pulley. The pulley enables the main rope to slide relative to the A counterweight, but cannot leave A. Counterweight. The main rope and counterweight rope are both pulled by the ho...

Abstract

The invention provides an external moving cable rotating system. The system is used for accelerating an uplink spacecraft so as to enable the spacecraft to enter an orbit. After the uplink spacecraftis in butt joint with the tail end of a main rope of the external moving cable rotating system, a winch unwinds cables, so that the spacecraft moves outwards on one side and rotates around the centerof mass on the other hand, and mechanical work generated by the cable is converted into electric energy to be stored by the winch or converted into heat energy of a brake. According to the method, theline speed and the centrifugal acceleration of the spacecraft after butt joint can be reduced. In particular, a retarder is arranged in the winch. By means of the method, centrifugal force can be greatly reduced, and comfort is improved. The winch is provided with the retarder with the large heat absorption capacity, so that the self-rotating energy of the system after butt joint can be absorbed,and that the spacecraft is guaranteed to quickly move outwards. By utilizing the winch, the system has an uplink method, so that a high centrifugal force stage of an uplink process of the spacecraftis short, and the comfort is high.

Description

technical field [0001] The invention belongs to the field of space, and relates to a space launch, a launch vehicle, a space transfer cable system, a hoist, and a brake, and in particular to a space transfer cable system for a spacecraft to ascend and move outward. Background technique [0002] Multi-disc brake discs are commonly used brakes on large aircraft. The structure is multi-disc, which consists of a force transmission cylinder, a shaft, a hydraulic component, and multiple brake pads. The brake pads are divided into static discs and moving discs. Usually, each static disc is on the inner side and connected to the shaft, and the moving disc is on the outer side, and the outer edge of each moving disc is connected to the force transmission cylinder. When braking, the hydraulic components generate thrust, which presses the alternately installed moving discs and static discs to generate friction torque to brake the aircraft. When the brake is released, the compressed re...
