Description

Technical Field

[0001] The present invention relates to the technical field of hoisting and erection, and particularly to a hoisting and erection device for a rocket offshore launch platform. Background Art

[0002] In the field of rocket launch, the launch platform is usually designed to consist of a fixed frame and an erection frame, and the two are hinged through a rotating shaft, so as to hoist and fix the rocket barrel assembly (the assembly of the rocket and the launch barrel) on the erection frame, and the erection frame is rotated around the rotating shaft through an erection system to complete the erection action of the rocket. For a traditional onshore launch platform, the actuating element of its erection system usually adopts a hydraulic cylinder. Because the hydraulic cylinder is a two-force bar structure, it can provide both tensile force and thrust, and the speed can be controlled by a hydraulic damping buffer structure to achieve smooth erection, without the problems of stall and impact. However, for an offshore launch platform, due to the limitation of the distance between the rotating shafts and the space of the launch ship, the hydraulic cylinder is no longer suitable as the actuating element of the erection system, and the offshore dynamic environment is relatively complex, and the hydraulic cylinder cannot achieve redundant backup, so the safety is poor. To solve this problem, the offshore launch platform usually adopts a flexible cable erection system. However, the current hoisting and erection device still has the following deficiencies:

[0003] First, when the existing hoisting and erection device performs the erection action of the erection frame, the rocket erection action is completely realized by the tensile force of the flexible cable. This not only has high requirements for the load-bearing performance of the cable, but also due to the influence of the connection position between the cable and the erection frame, the erection frame is not stable enough during erection;

[0004] Second, although the existing hoisting and erection device is provided with an auxiliary fixing structure at the bottom of the fixed frame, generally, the stability of the fixed frame is enhanced by connecting to the top of the offshore launch platform, and the grasping force of the fixed frame on the launch platform is poor. Therefore, it is not conducive to providing a stable working environment for the winch.

[0005] Therefore, it is urgent to improve this shortcoming. The present invention studies and improves the existing structure and deficiencies, and provides a hoisting and erection device for a rocket offshore launch platform. Summary of the Invention

[0017] The present invention provides a hoisting and erecting device for a rocket sea launch pad frame, having the following beneficial effects:

[0018] 1. The present invention is provided with an auxiliary support assembly. The servo motor drives the metal lead screw to rotate along the inner wall of the thread sleeve. Since the outer wall of the thread sleeve is connected with a sliding rod, and the second sliding member at the end of the sliding rod is restricted by the track of the second sliding groove, as the metal lead screw rotates, the sliding rod will be driven to move along the track of the second sliding groove, thereby driving the push rod to push the support cylinder to move along the upper surface of the fixed slope, providing a supporting force for the bottom of the gradually erecting erecting frame. When the improved hoisting and erecting device performs the erecting action of the erecting frame, through the combined use of the tension of the flexible steel cable and the auxiliary supporting force, the rocket erecting action is realized, which not only reduces the bearing capacity of the flexible steel cable, but also improves the stability of the erecting frame during erection.

[0019] 2. The present invention is provided with an auxiliary fixing component, which is jointly composed of a support column, a first chute and a buried component. The bottom four corners of the fixing frame are supported by the base, and the semi-buried design of the central column body makes its connection with the ground of the launch pad closer. The support frame is divided into two parts, the surface part and the underground part. Every three support rods can be assembled into a hollow triangular pyramid shape through a connector, so that a triangle can be formed between any two support rods to stably support the bottom of the fixing frame. Moreover, the support rods are connected through the surface substrate in a penetrating manner, and the surface substrate is fixed on the ground of the offshore launch pad through fastening bolts, which can grasp its surface. In addition, the buried component can not only build a connection between the support column and the support frame to enhance the correlation between components, but also, by using the support column, the first chute and the buried component in cooperation, can enhance the grasping and fixing of the support column and the support frame to the underground of the offshore launch pad. The improved hoisting and erecting device has a better fixing effect on the fixing frame, enhances its connection effect with the offshore launch pad frame, makes the grasping force of the fixing frame on the launch pad frame better, so as to improve the stability of the fixing frame and is beneficial to providing a stable working environment for the winch.

The support cylinder 1014 can be pushed by the push rod 1013 to move along the upper surface of the fixed slope 1006, so as to support the erecting frame 3 that is gradually erected.

[0029] Such as Figure 1 , Figure 5 and Figure 6As shown in the figure, a secondary fixing component 11 is fixedly connected to the bottom of the fixing frame 1, and the fixing frame 1 is erected on the offshore launch pad through the secondary fixing component 11. The secondary fixing component 11 includes a support column 1101, a first chute 1002, and an embedding member 1103. The support column 1101 includes a central column body 11011, a conical seat 11012, and a connecting sleeve 11013. The top of the central column body 11011 is fixedly connected to the bottom of the fixing frame 1, the bottom of the central column body 11011 is fixedly connected to the conical seat 11012, and the outer wall of the connecting sleeve 11013 is sleeved with the connecting sleeve 11013. At the same time, the inner wall of the connecting sleeve 11013 is fixedly connected and fitted with the outer wall of the central column body 11011. By setting the support column 1101, the four corner positions at the bottom of the fixing frame 1 can be supported. And the semi-embedded design of the central column body 11011 makes its connection with the launch pad ground closer. The support frame 1102 includes a connecting head 11021, a support rod 11022, a surface substrate 11023, and a fastening bolt 11024. The top of the connecting head 11021 is welded to the bottom of the fixing frame 1, and the inner wall of the connecting head 11021 is fixedly connected to the support rod 11022. The support rod 11022 is connected through the surface substrate 11023, and a fastening bolt 11024 is arranged on the top of the surface substrate 11023. And the surface substrate 11023 is fixed on the ground of the offshore launch pad through the fastening bolt 11024. By setting the connecting head 11021, every three support rods 11022 can be assembled into a hollow triangular pyramid shape, so that the support rods 11022 can form a triangle between each other to support the bottom of the fixing frame 1. And the support frame 1102 is divided into two parts, the surface and the underground. By using the surface substrate 11023 and the fastening bolt 11024, the ground of the offshore launch pad can be grasped. The embedding member 1103 includes an underground substrate 11031, a ground-inserting cone 11032, and a connecting ring 11033. The underground substrate 11031 is buried inside the offshore launch pad, the bottom of the underground substrate 11031 is welded with the ground-inserting cone 11032, and the side of the underground substrate 11031 is welded with the connecting ring 11033. At the same time, the inner wall of the connecting ring 11033 is fixedly connected to the outer wall of the support column 1101. By setting the embedding member 1103, not only can a connection be built between the support column 1101 and the support frame 1102 to enhance the correlation between components, but also by using the support column 1101, the first chute 1002 and the embedding member 1103 in cooperation, the grasping and fixing of the support column 1101 and the support frame 1102 to the underground of the offshore launch pad can be enhanced. The outer wall of the secondary fixing component 11 is fixedly connected to a connecting frame 12, and one side of the connecting frame 12 is fixedly connected to a reinforcing support member 13.

[0030] In summary, in combination with Figures 1-6As shown in the figure, the working principle of the hoisting and erection device of the rocket offshore launch platform is as follows: First, install the rocket on the erection frame 3, and then start the winch 7 and the servo motor 1008. Use the winch 7 to wind up the steel wire rope 6. As the steel wire rope 6 shortens, the distance between the connecting ring 5 and the fixed roller 9 gradually shortens, and the erection frame 3 gradually starts to be erected. At the same time, the metal screw rod 1009 rotates along the inner wall of the thread sleeve 1011 under the drive of the servo motor 1008. Since the outer wall of the thread sleeve 1011 is connected with a slide bar 1012, and the second slider 1005 at the end of the slide bar 1012 is restricted by the track of the second chute 1004, as the metal screw rod 1009 rotates, it will drive the slide bar 1012 to move along the track of the second chute 1004, thereby driving the push rod 1013 to push the support cylinder 1014 to move. And because both ends of the support cylinder 1014 are connected with the first slider 1003, through the cooperation of the first chute 1002 and the first slider 1003, the movement track of the support cylinder 1014 can be restricted, so that after being subjected to the thrust of the push rod 1013, it can only move along the upper surface of the fixed slope 1006, providing a supporting force for the bottom of the gradually erected erection frame 3. During this process, the auxiliary fixing component 11 at the bottom of the fixed frame 1 will play a good role in supporting and anti-hoisting. The auxiliary fixing component 11 is jointly composed of the support column 1101, the first chute 1002 and the embedding part 1103. Support the four corner positions of the bottom of the fixed frame 1 through the base 1001, and the semi-embedded design of the central column body 11011 makes its connection with the launch pad ground closer. The support frame 1102 is divided into two parts, the surface and the underground. Every three support rods 11022 can be assembled into a hollow triangular pyramid shape through the connector 11021, so that a triangle can be formed between every two support rods 11022 to stably support the bottom of the fixed frame 1, and the support rod 11022 is connected through the surface substrate 11023. The surface substrate 11023 is fixed on the ground of the offshore launch platform through the fastening bolt 11024, and can grab its surface. In addition, the embedding part 1103 can build a connection between the support column 1101 and the support frame 1102, enhancing the correlation between the components. And by using the support column 1101, the first chute 1002 and the embedding part 1103 in cooperation, the grasping and fixing of the support column 1101 and the support frame 1102 to the underground of the offshore launch platform can be enhanced. Through the auxiliary fixing component 11, the fixed frame 1 can be stably installed on the launch pad ground, providing a stable working environment for the winch 7, making the winding of the steel wire rope 6 and the erection of the erection frame 3 smoother.
