[0039] The main body of the launch rack 2 is an L-shaped structure and rotates around the rotating shaft 15. A bearing end cover 24 is arranged on the launch rack 2. A pitching servo motor 20, a gear 22, an ear 23, and a connection hole 241 are arranged on the bearing end cover 24. A groove 242 is arranged in the connection hole 241.

[0044] An azimuth servo motor 28, an azimuth rotary encoder 30, an azimuth gear 31 and a turntable bearing 32 are provided in the middle of the turret 4. The azimuth servo motor 28 and the azimuth rotary encoder 30 are respectively provided on both sides of the erection servo motor 9. The azimuth servo motor 28 drives the azimuth gear 31 to rotate through the azimuth servo motor reducer 29. The azimuth rotary encoder 30 and the azimuth gear 31 are engaged with the turntable bearing 32, playing a role in driving the turret 4 to rotate horizontally and instantaneously measuring the azimuth angle of the turret 4 to ensure the horizontal azimuth tracking angle of the launch rack 3. The turret 4 is an integrated platform. The turntable bearing 32 is provided at the bottom of the turret 4 and is connected to equipment such as the chassis or fixed frame to ensure that the turret 4 makes a horizontal rotation movement to adjust the azimuth angle of the launch rack 3.

[0045] Link A6 is triangular. Hole C61, hole D62 and hole E63 are provided on link A6. Link A6 is hinged to link B7 through hole C61, link A6 is hinged to link C8 through hole D62, and link A6 is connected to the rotating shaft 15 through hole E63.

[0046] A boss 37 is provided on the fixing plate 33. The adapter bracket 3 is positioned with the mounting groove on the launch rack 2 through the boss 37 and fixed to the launch rack 2 with screws.

[0047] The working principle of this launch mechanism is as follows:

[0048] The mounting bases 5, connecting rod A6, connecting rod B7, and connecting rod C8 on the same side form a four-bar linkage mechanism.

[0049] In the homing state, the four-bar linkage mechanism of the erection mechanism 1 is in a rectangular state. During operation, the erection servo motor 9 drives the two side lead screws 13 to extend synchronously through the reversing speed reducer 10, coupling 11, and bevel gear speed reducer 12. The lead screw 13 drives the connecting rod B7 to rotate around the axis of the mounting hole on the mounting base 5 and drives the hinge shaft 14 to rotate synchronously. The hinge shaft 14 drives the touch nut 16 to rotate synchronously. With the mounting base 5 as the fixed side, the erection mechanism 1 moves upward as a whole with the four-bar linkage mechanism. The connecting rod A6 and the rotation axis of the tooth arc 17 always maintain a horizontal upward movement state. The launch rack 2 mounted by the rotation axis 15 and the tooth arc 17 is lifted horizontally, which ensures that the launch rack 2 and the adapter frame 3 move horizontally upward during erection. When the erection mechanism 1 reaches the required height, the touch nut 26 contacts one side of the proximity switch 25 and feeds back a signal to stop the erection servo motor 9, and the erection process is completed. This is the erection state.

[0050] After the erection process is completed, the elevation servo motor 20 is started to perform an elevation movement. The elevation servo motor 20 drives the gear 22 to rotate through the elevation motor speed reducer 21. The gear 22 engages with the tooth arc 17 and makes a circular motion around the tooth arc 17. The tooth arc 17 is fixed on the connecting rod A6. At this time, the tooth arc 17 does not perform rotational or translational movements. Since the launch rack 2 is hinged to the rotation axis 15 through the support ear 23, and the rotation axis 15 is concentric with the tooth arc 17, the launch rack 2 rotates around the rotation axis 15 and drives the rotation axis 15 to rotate synchronously through the mounting key 19. At this time, the rotation angle of the rotation axis 15 is the elevation angle of the launch rack 2, which is immediately fed back through the azimuth rotation encoder 30 installed at the center of the tooth arc 17. The launch racks 2 on both sides of the launch mechanism are independently controlled by their respective elevation servo motors 21, and different elevation angles can be generated for the launch racks 2 on both sides according to requirements.

[0051] When changing to the homing state, the elevation servo motor 20 drives the gear 22 to rotate the launch rack 2 to the horizontal position and changes to the erection state. Then, the erection servo motor 9 is started to contract the two side lead screws 13 synchronously, and the erection mechanism 1 gradually returns to the horizontal rectangular state. At this time, the positioning pin 16 drives the hinge shaft 14 to make a rotational movement in the opposite direction to that during erection. When the touch nut 26 contacts the other side of the proximity switch 25, the erection servo motor 9 stops working, and the entire structure is homed.

[0052] During the above working process, the azimuth servo motor 28 and the azimuth servo motor speed reducer 29 can be used to drive the azimuth gear 31 to rotate at any time. The azimuth gear 31 engages with the slewing bearing 32 to drive the turret 4 and the equipment thereon to rotate horizontally, and the required instantaneous azimuth angle of the launch rack 2 is ensured by measuring the azimuth angle through the azimuth rotation encoder 30.
