Embodiment Construction
[0022] A specific embodiment will be described in detail below in conjunction with the accompanying drawings.
[0023] Please refer to figure 1 , a connector pneumatic servo device, including a frame 1, a linkage 9, a cylinder assembly 11 and a guide mechanism 10:
[0024] The frame 1 is provided with a first cylinder 2, a movable pulley block 3, a fixed pulley block and a steel wire rope 7, the movable pulley block 3 is connected to the output end of the first cylinder 2, and the steel wire rope 7 bypasses the movable pulley block 3. After the fixed pulley block is connected with the linkage mechanism 9; wherein, the fixed pulley block includes a first fixed pulley block 4 and a second fixed pulley block 5, and the first fixed pulley block 4 is located above the movable pulley block 3, so that The second fixed pulley 5 is located on the outside of the first fixed pulley 4 and above the connecting rod mechanism 9, and the steel wire rope 7 can wind around the movable pulley 3...

The invention relates to a connecting device pneumatic following up device. The connecting device pneumatic following up device includes a rack, a connecting rod mechanism, an air cylinder assembly and a guiding mechanism. The rack is provided with a first air cylinder, a movable pulley set, a fixed pulley set and a steel wire rope. The movable pulley set is connected with the output end of the first air cylinder. The steel wire rope is connected with the connecting rod mechanism after bypassing the movable pulley set and the fixed pulley set. The rack is further provided with a guiding rail.The guiding rail is movably provided with a bearing. One end of the connecting rod mechanism is connected with the bearing and the other end of the connecting rod mechanism is movably connected with the guiding mechanism. One end of the air cylinder assembly is connected with the bearing and the other end of the air cylinder assembly is connected with the guiding mechanism. The guiding mechanism is connected with the connecting device. The connecting device shakes along with the rocket body after the connecting device conducts butt joint with the connecting port on a rocket. The guiding mechanism can be shaken following the connecting device. The connecting device pneumatic following up device is low in mass, simple in structure and convenient to operate; the automatic butt joint of the connecting device and the connecting port on the rocket can be achieved; the connecting device moves following up shaking of the rocket body; and the connecting device pneumatic following up device hasthe beneficial effects that the connecting port on the rocket cannot be damaged due to the fact that an additional drag force cannot be produced to the rocket body.
Description
technical field [0001] The invention relates to the technical field of connector actuation, in particular to a connector pneumatic actuation device. Background technique [0002] In the process of rocket filling, gas supply and distribution, the rocket body will have a slight shaking in an uncertain direction and filling sinking due to the influence of external forces such as wind. In order to reduce the rocking or sinking process of the rocket body, the connector on The restraining force of the interface on the arrow needs to be equipped with a connector follower. At present, in a new generation of rockets, a connector follower device in the form of a counterweight is used to balance the weight of the venting connector and its pipeline, and follow the rocking of the rocket body, which can effectively reduce the force on the rocket body , to protect the arrow-on interface. However, this follow-up mechanism has a relatively large mass, complicated installation, and complex ...
