[0047] As shown in Figure 6, this application also provides a disconnection method applied to the aforementioned auxiliary disconnection device with redundant backup. The disconnection method includes the following steps:

[0048] S1: When in use, install the auxiliary release device with redundancy backup, connect the other end of the vertical beam of the auxiliary release device with redundancy backup to the erecting frame, and connect the release plug to the corresponding part of the arrow body.

[0049] S2: After installation is completed, the first electric push rod and / or the second electric push rod with redundant backup auxiliary release device receive the separation command sent by the control center, wherein the separation command includes at least: release time and release force.

[0050] Specifically, the separation time is the time required to complete the separation operation.

[0051] Pull-out force is the force required to complete the separation operation.

[0052] Furthermore, the pull-out force is greater than the theoretical pull-out value.

[0053] Specifically, as long as the first electric push rod and / or the second electric push rod provide a pulling force greater than the theoretical pulling value, the plug can be smoothly detached under the action of the connecting steel wire rope without jamming.

[0054] As one embodiment, when only the other end of the electric push rod pulling the steel wire rope of the first electric push rod is set in the intermediate connecting rod base, the first electric push rod receives and executes the separation command and provides the corresponding pull-out force. When the first electric push rod is damaged and cannot work normally, the second electric push rod is used to replace the first electric push rod, and the second electric push rod receives and executes the separation command and provides the corresponding pull-out force.

[0055] In another embodiment, when the other ends of the electric push rod pulling wire ropes of the first electric push rod and the second electric push rod are both located in the intermediate connecting rod base, the first and second electric push rods jointly receive and execute the separation command, providing the corresponding pull-out force. When the first or second electric push rod is damaged and cannot work normally, the undamaged second or first electric push rod is used as a backup electric push rod, which receives and executes the separation command, providing the corresponding pull-out force.

[0056] S3: The first electric push rod and / or the second electric push rod provide the corresponding pull-out force according to the separation command. The disconnector is dislodged under the action of the pull-out force, and the wire rope connected to the disconnector moves downward and outward around the lifting ring until the disconnector is stationary, and the separation operation is completed.

[0057] Specifically, the auxiliary release device with redundancy creates a hinge point at the lifting ring, which can accommodate deviations in the arrow body to ensure the safety and reliability of the release plug's detachment, and to achieve controllable detachment trajectory and landing point. The deviations include at least: ±30mm in the arrow body length direction (i.e., the X direction), ±60mm in the left-right direction, and ±3° of deflection around its own axis.

[0058] When the disconnect plug detaches, the connecting wire rope of the disconnect plug can play a deflecting role under the action of the lifting ring. When the arrow body deviates to a certain extent, the force direction of the connecting wire rope of the disconnect plug is collinear with the disconnection direction. The connecting wire rope of the disconnect plug is collinear with the rod diameter direction of the first electric push rod and / or the second electric push rod. Therefore, the lateral force generated by each device is reduced, the reliability of the first electric push rod and / or the second electric push rod and the reliability of the disconnect plug detachment are improved, and it can adapt to larger deviations.

[0059] The beneficial effects achieved by this application are as follows:

[0060] (1) The first electric push rod and the second electric push rod are backup electric push rods for each other. When one of the electric push rods is damaged, the other undamaged electric push rod can continue to perform the separation operation as the driving element, which improves the driving reliability.

[0061] (2) The trajectory and landing point of the disconnect plug are controllable, which can prevent the disconnect plug from colliding with the erecting frame or product due to sudden drop, causing scratches on the arrow body or damage to the disconnect plug structure, thus improving the reliability of disconnection.

[0062] Although preferred embodiments of this application have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the scope of protection of this application is intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application. Obviously, those skilled in the art can make various alterations and variations to this application without departing from the spirit and scope of this application. Thus, if these modifications and variations of this application fall within the scope of protection of this application and its equivalents, this application also intends to include these modifications and variations.

8. The auxiliary disconnection device with redundant backup according to claim 7, characterized in that, The lower connecting rod accessories include at least: a lower connecting rod base, a lower connecting rod shaft end retaining ring, a lower connecting rod pin, a lower connecting rod locking cover, and at least four lower connecting rod screws; one end of the lower connecting rod base is connected to one end of the lower connecting rod shaft end retaining ring, and the other end of the lower connecting rod shaft end retaining ring is connected to the shaft of the disconnect plug; the other end of the disconnect plug connecting wire rope is located inside the lower connecting rod base and is connected to the lower connecting rod pin; the lower connecting rod locking cover is connected to the lower connecting rod base through the lower connecting rod screws, and the connection forms a lower cavity, with the other end of the disconnect plug connecting wire rope and the lower connecting rod pin both located inside the lower cavity.

9. A method for detachment, characterized in that, The auxiliary release device with redundancy backup as described in any one of claims 1-8 is used in a release method comprising the following steps: S1: When in use, the auxiliary release device with redundancy backup is installed, and the other end of the vertical beam of the auxiliary release device with redundancy backup is connected to the erecting frame, and the release plug is connected to the corresponding component of the arrow body. S2: After installation, the first and / or second electric push rods with redundant backup auxiliary release devices receive a separation command sent by the control center. The separation command includes at least: release time and release force. S3: The first and / or second electric push rods provide the corresponding release force according to the separation command. The release connector detaches under the action of the release force and moves downward and outward around the lifting ring via the release plug-connected wire rope until the release plug is stationary, completing the separation operation. The first and second electric push rods are backup electric push rods for each other. When one electric push rod fails, the other undamaged electric push rod can continue the separation operation as the driving element. Specifically, this includes setting only the other end of the pull wire rope of the first electric push rod on the intermediate connecting rod. When the first electric push rod is inside the base, it receives and executes the separation command, providing the corresponding pull-out force. When the first electric push rod is damaged and cannot work normally, the second electric push rod is used to replace the first electric push rod, and the second electric push rod receives and executes the separation command, providing the corresponding pull-out force. Alternatively, when the other ends of the pull-out wire ropes of the first and second electric push rods are both located inside the base of the intermediate connecting rod, the first and second electric push rods jointly receive and execute the separation command, providing the corresponding pull-out force. When either the first or second electric push rod is damaged and cannot work normally, the undamaged second or first electric push rod is used as a backup electric push rod, and the backup electric push rod receives and executes the separation command, providing the corresponding pull-out force.
