[0002] After the launch vehicle is hoisted onto the launch pad, there will be a deviation in the relative position between the rocket and the launch pad. During the preparation for a certain type of rocket launch mission, the auxiliary release device needs to adapt to the change in the relative position of the launch vehicle during release, ensuring that the direction of the pulling force is coaxial with the direction of release to ensure smooth release.

Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] like Figure 1-4As shown, this application provides a multi-degree-of-freedom adjustable auxiliary release device, which includes: a mounting base 1, an adjustment mechanism 2, an electric actuator mounting bracket 3, an electric actuator 4, and a release cable 6. The mounting base 1 is fixedly connected to the launcher. The top end of the adjustment mechanism 2 is fixedly connected to the mounting base 1, and the bottom end is fixedly connected to the electric actuator mounting bracket 3. That is, the adjustment mechanism 2 is fixedly connected to the bottom of the mounting base 1. The adjustment mechanism 2 is used to adjust the degree of freedom of the electric actuator mounting bracket 3. The electric actuator 4 is fixedly connected to the electric actuator mounting bracket 3. The adjustment mechanism 2 adjusts the degree of freedom of the electric actuator mounting bracket 3 and the electric actuator 4 at the same time. The electric actuator mounting bracket 3 is fixedly connected to the side of the adjustment mechanism 2. One end of the release cable 6 is connected to the tail end of the release plug 14, and the other end is connected to the electric actuator 4. When the electric actuator 4 retracts, it pulls the release plug 14 to detach. The steel cable 6, connected to the disconnect plug 14, extends along the direction in which the disconnect plug 14 is pulled out, while the electric push rod 4 extends parallel to the direction of extension of the disconnect plug 14. When the electric push rod 4 is activated, it exerts a pulling force on the steel cable 6, which in turn exerts a pulling force on the disconnect plug 14. Since the steel cable 6 and the disconnect plug 14 extend along the direction in which the disconnect plug 14 is pulled out, and the electric push rod 4 extends parallel to the direction of extension of the disconnect plug 14, when the direction of the pulling force provided by the electric push rod 4 is not aligned with the axis of the disconnect plug 14, the degree of freedom of the electric push rod 4 is adjusted by the adjusting mechanism 2 to ensure that the direction of the pulling force provided by the electric push rod 4 is aligned with the axis of the disconnect plug 14. Therefore, it can be ensured that the direction of the pulling force of the auxiliary disconnecting device on the disconnect plug 14 is aligned with the axis of the disconnect plug 14, preventing the pulling force from being out of alignment with the disconnecting direction and avoiding damage to the disconnect socket on the arrow.

[0025] like Figure 1-4 As shown, the adjustment mechanism 2 includes a translation slide 7 and a lifting slide 8. The translation slide 7 is installed at the bottom of the mounting base 1. The lifting slide 8 is located below the translation slide 7, that is, the lifting slide 8 is located on the side of the translation slide 7 away from the mounting base 1. The lifting slide 8 is fixedly connected to the electric actuator mounting bracket 3 and is connected to the translation slide 7 through a rotation adjustment mechanism. The rotation adjustment mechanism can adjust the lifting slide 8 to swing at a certain angle relative to the translation slide 7, thereby adjusting the angle between the lifting slide 8 and the mounting base 1. The translation slide 7 can adjust the horizontal relative movement between the entire auxiliary release device and the mounting base 1. The lifting slide 8 can adjust the vertical relative movement between the entire auxiliary release device and the mounting base 1.

[0026] like Figure 1-4As shown, the rotation adjustment mechanism is connected between the translation slide 7 and the lifting slide 8. The rotation adjustment mechanism includes: a hinge seat 9, a ball bearing 10, a self-lubricating bearing 11, an adjusting rod 12, and a connecting rod 13. The connecting rod 13 includes: a first connecting rod and a second connecting rod. The two ends of the adjusting rod 12 are respectively connected to the translation slide 7 and the lifting slide 8 through the hinge seat 9; the two ends of the first connecting rod are respectively connected to the translation slide 7 and the lifting slide 8 through the ball bearing 10; the two ends of the second connecting rod are respectively connected to the translation slide 7 and the lifting slide 8 through the self-lubricating bearing 11, so as to realize the adjustment of the two rotational degrees of freedom between the translation slide 7 and the lifting slide 8.

[0027] In a specific embodiment of the present invention, the electric push rod 4 includes a first electric push rod and a second electric push rod; the first and second electric push rods are arranged in parallel and spaced apart. Both the first and second electric push rods can pull the release cable 6. If one of them is not working, it does not affect the pulling effect of the other on the release cable 6. The release is achieved by one electric push rod pulling the release cable 6. It can be understood that the two electric push rods are redundant. No matter which electric push rod fails, the other electric push rod can still release the cable 6.

[0028] like Figure 1 As shown, the release cable 6 includes three cables, which are connected together by a triangular connector 61; one of the three cables is connected to the tail end of the release plug 14, and the other two cables are connected to the first electric push rod and the second electric push rod, respectively.

[0029] Understandably, the release cable 6 consists of three cables and a triangular connector 61. The triangular connector 61 connects the three cables together. Two of the cables are connected to the tops of the two electric push rods through the cable fixing piece 5. One end of the other cable is connected to the tail end of the release plug 14. When the electric push rod retracts, the release plug can be pulled out.

[0030] like Figure 1 , 4As shown, a horizontal connecting platform 21 is fixedly connected to the top of the lifting slide 8; a first hinge seat is fixedly connected to the horizontal connecting platform 21; a second hinge seat is fixedly connected to the bottom of the translation slide 7; an adjusting rod 12 connects the first hinge seat and the second hinge seat, i.e., one end of the adjusting rod 12 is connected to the first hinge seat and the other end is connected to the second hinge seat. The horizontal connecting platform 21 is connected to the translation slide 7 through the adjusting rod 12. The horizontal connecting platform 21 can rotate around the second hinge seat through the adjusting rod 12, and the horizontal connecting platform 21 can also rotate around the first hinge seat. That is, the horizontal connecting platform 21 can tilt at a certain angle in two directions relative to the translation slide 7. It should be explained that the horizontal connecting platform 21 can rotate around the second hinge seat through the adjusting rod 12 to provide a tilt angle in the first direction, and the horizontal connecting platform 21 can also rotate around the first hinge seat to provide a tilt angle in the second direction.

[0031] like Figure 4 As shown, a sliding slide 7 is provided with a sliding slide handwheel 15 on its side; a lifting slide 8 is provided with a lifting slide handwheel 16 on its side. By manually rotating the sliding slide handwheel 15, the relative movement of the sliding slide 7 with respect to the mounting base 1 in the horizontal direction can be adjusted. By manually rotating the lifting slide handwheel 16, the relative movement of the lifting slide 8 with respect to the mounting base 1 in the vertical direction can be adjusted.

[0032] In a specific embodiment of the present invention, the triangular connector 61 includes three connecting holes; the three connecting holes are located at the three corners of the triangular connector 61; three steel cables are respectively connected to the three connecting holes. The steel cables are connected to the end of the electric push rod 4 through the steel cable fixing member 5.

[0033] Understandably, the adjustment device can achieve four degrees of freedom adjustment, including two translational degrees of freedom and two rotational degrees of freedom. The adjustment mechanism 2 includes a translational slide 7 and a lifting slide 8. The translational slide is mounted on the mounting base 1, and the electric actuator mounting bracket 3 is mounted on the lifting slide 8. The two slides can achieve the adjustment of two translational degrees of freedom. Each slide is equipped with a hinge seat 9, a ball bearing 10, and a self-lubricating bearing 11. The two slides are connected by an adjustment rod 12 and two bearings with connecting rods 13 at both ends. The adjustment rod 12 is connected to the hinge seat 9 connecting the two slides. The two connecting rods 13 are threaded to the ball bearing 10 and the self-lubricating bearing 11 of the two slides, respectively. By turning the connecting rods 13, the two rotational degrees of freedom between the two slides can be adjusted.

[0034] The beneficial effects achieved by this application are as follows:

[0035] (1) The auxiliary detachment device of this application adapts to the relative position change of the launch vehicle detachment, ensures that the pulling force on the detachment plug is coaxial with the detachment plug, prevents the pulling force from being out of axis with the detachment direction, and uses the auxiliary detachment device to detach, avoiding the problem of damaging the detachment socket on the rocket, and the auxiliary detachment is successfully detached.
