[0019] In the description of the utility model, it is necessary to explain that, unless another explicit provision and limitation, the term "connection" should be understood in a broad sense, for example, it can be fixed connection, can also be detachable connection, or integrally connected, can be mechanical connection, can also be electrical connection, can be directly connected, also can be indirectly connected through the intermediate medium. For ordinary skilled in the art, the specific meaning of the above-mentioned term in the utility model can be understood according to the specific circumstances.

[0020] Figure 1 And Figure 2The lifeboat / raft launching device shown includes a stabilizing mechanism, comprising a mounting base 1, an electrically controlled lifting arm 2 movably mounted on the upper end of the mounting base 1, a power unit 3 fixedly mounted on the outer wall of the longitudinal section of the electrically controlled lifting arm 2, a top-mounted hoisting unit 4 controlled by the power unit 3 movably mounted on the top of the electrically controlled lifting arm 2, and an electrically controlled stabilizing disc 5 elastically mounted inside the electrically controlled lifting arm 2 to improve the stability of the top-mounted hoisting unit 4.

[0021] The suspension rope on the top-mounted hoisting unit passes around the guide wheel on the electrically controlled lifting arm 2 and connects to the power unit 3. The power unit 3 is used to control the lifting and adjustment of the top-mounted hoisting unit.

[0022] To facilitate angle adjustment, the electrically controlled lifting boom 2 includes a lifting boom 22 mounted on the mounting base 1 via a bottom turntable 21 and a rotary motor 23 fixed to the side wall of the lifting boom 22.

[0023] The output end of the rotary motor 23 is engaged with the upper surface of the mounting base 1 through the adjusting wheel. The rotary motor 23 drives the adjusting wheel to rotate, thereby controlling the rotation and adjustment of the bottom turntable 21 and the lifting arm 22 at its upper end.

[0024] To facilitate stability adjustment, the electrically controlled stabilizing plate 5 includes an annular bottom adjusting plate 51 movably mounted on the lower surface of the end of the boom 22, an electrically controlled adjusting frame 52 movably mounted on the lower end of the annular bottom adjusting plate 51, and an electrically controlled winch 53 fixed to the lower end of the electrically controlled adjusting frame 52.

[0025] The internal winch rope of the electrically controlled winch 53 extends out and connects to the suspension rope of the top-mounted hoisting unit.

[0026] To facilitate bottom movable assembly and angle adjustment, a bottom side assembly frame for movable assembly of the annular bottom adjustment plate 51 is welded and fixed to the lower end of the lifting boom 22. The annular bottom adjustment plate 51 is movably connected to the bottom side assembly frame through the rotating shafts at both ends of the lateral assembly bracket. A bottom side adjustment support rod 54 for controlling the annular bottom adjustment plate 51 is movably assembled on the lower surface of the lifting boom 22.

[0027] The bottom adjustment support rod 54 controls the flip adjustment of the annular bottom adjustment plate 51 by telescopic movement, thereby ensuring that the annular bottom adjustment plate 51 can always remain horizontal.

[0028] To facilitate angle adjustment, the electronically controlled adjustment frame 52 includes an adjustment ring 521 movably installed in the mounting groove at the lower end of the annular bottom adjustment plate 51 and a top control motor 522 fixedly installed at the upper end of the annular bottom adjustment plate 51. The top control motor 522 engages with the adjustment ring 521 through an adjustment gear 523 on the bottom output shaft.

[0029] The adjusting ring 521 has an annular toothed groove on its side wall that meshes with the adjusting gear 523. The top control motor 522 drives the adjusting ring 521 to rotate by driving the adjusting gear 523.

[0030] To facilitate optical positioning, an optical monitoring module 6 is fixedly mounted on the inner arc-shaped surface of the annular bottom adjustment plate 51.

[0031] The optical monitoring module 6 uses three-point positioning and is evenly installed in three directions on the inner arc surface of the annular bottom adjustment plate 51. Under normal circumstances, the optical monitoring module 6 can detect the suspension rope on the top hoisting unit 4. Once the optical monitoring module 6 fails to detect the suspension rope on the top hoisting unit 4, the top control motor 522 drives the adjustment ring 521 to rotate through the adjustment gear 523 on the bottom output shaft, adjusting the position of the electric winch 53. One optical monitoring module 6 is fixed in the same position on the electric winch 53. The optical monitoring module 6 detects the suspension rope on the top hoisting unit 4 again. If the detection distance is greater than the distance of the set center position, the optical monitoring module 6 in the same position on the electric winch 53 rotates through the adjustment ring 521 until the detection distance is less than the distance of the set center position. Then the electric winch 53 is started, and the pull rope extending outward from the electric winch 53 pulls the suspension rope on the top hoisting unit 4, thereby pulling in the opposite direction and improving its stability.

[0032] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
