[0003] The currently used launching platform cannot fully meet the demand of rapid response of offshore launching tasks, when the sea condition is greater than 4, the sway amplitude of the launching platform changes greatly under the action of environmental loads such as wind, wave and current, which will bring large initial aiming error and positioning error to the carrier rocket, and even cannot complete the aiming work, resulting in that the launching procedure cannot be entered, the original launching window will be delayed, and the time, manpower and financial cost will be greatly increased. In order to solve the problem that the launching platform and the rocket greatly sway under the action of environmental loads such as wind, wave and current during the offshore launching of the carrier rocket, it is necessary to base on the existing solid rocket type of offshore launching and the offshore launching support system, bypass the dynamic base aiming technology, comprehensively consider the influence of wave force and wind load on the movement of the launching platform and the rocket, and propose a servo carrier platform configuration for the stability of the rocket body for offshore launching.

The launch platform 1 is the deck of a ship body, the head-tail direction of the deck is the longitudinal direction, the transverse displacement stroke of the first moving plate 2 in the transverse direction is greater than the longitudinal displacement stroke of the second moving plate 3 in the longitudinal direction. The transverse displacement of the first moving plate 2 and the longitudinal displacement of the second moving plate 3 are both driven by a motor. The rotation of the first support 5 on the base 4, the rotation of the cross shaft 6 around the first shaft 601, and the rotation of the second support 7 around the second shaft 602 are all driven by a motor. The first support 5 includes a ring support 501 and two connecting ears 502 oppositely arranged on the ring support, the connecting ears 502 are used to rotatably connect with the first shaft 601, and the ring support 501 is rotatably arranged on the base 4. The second support 7 has the same structure as the first support 5, and the two connecting ears 502 of the second support 7 are rotatably connected with the second shaft 602. Further, a support plate 8 is arranged on the upper end of the second support 7, the rocket 9 is arranged on the support plate 8, and the rocket 9 is arranged on the second support 7 through the support plate 8 and moves with the second support 7.

[0034] Figure 1 As shown, the launch platform 1 is subjected to the action of wind and waves, and the deck of the launch platform 1 performs periodic oscillation motion, including roll, pitch, yaw, sway, surge, and heave. When the rocket 9 is vertically arranged on the launch platform 1, roll, pitch, yaw, sway, and surge will all affect the horizontal and vertical state of the rocket 9. Among the six irregular motions that affect the rocket 9, sway, surge, and yaw can be compensated by the dynamic positioning system or anchoring technology of the launch platform 1, and have little effect on the vertical state of the rocket 9. It is difficult to compensate for roll, pitch, and heave by the launch platform 1 itself. Compared with roll motion, the period and amplitude of pitch motion are generally small.

[0035] In use, a special track 101 can be built on the deck for the first moving plate 2 to travel, and the contact mode can adopt a wheel type track 101 structure to enable the first moving plate 2 to travel stably and moveably, and the first moving plate 2 can be driven by a motor to move laterally to correct the reciprocating movement (lateral displacement) of the rocket 9 relative to the left and right directions of the launching platform 1, and the second moving plate 3 can also move on the first moving plate 2 through the track 101 and a wheel type structure, and can be driven by a motor to move longitudinally to correct the displacement (longitudinal displacement) of the rocket 9 relative to the head and tail directions of the launching platform 1.

[0036] As shown in Figures 3-6 The base 4, the first support 5, the cross shaft 6 and the second support 7 form a gimbal structure, and the X, Y and Z three axes can be freely rotated by a motor drive, and the reciprocating shaking of the launching platform 1 around the longitudinal axis, the lateral axis and the vertical axis is eliminated through the X, Y and Z three-axis rotating structure. The motor drive is a prior art, and those skilled in the art can realize it.

[0037] Generally, the left and right shaking amplitude of the launching platform 1 is larger than the front and back (head and tail direction) shaking amplitude, and the left and right direction displacement length is also longer than the head and tail direction displacement length. The lateral displacement stroke of the first moving plate 2 in the lateral direction refers to the maximum stroke of the first moving plate 2 in the lateral direction, and the longitudinal displacement stroke of the second moving plate 3 in the longitudinal direction refers to the maximum stroke of the second moving plate 3 in the longitudinal direction.
