Description

Technical Field

[0001] This application relates to the field of rocket technology, and in particular to a lifting device for a sea launch vessel and command vessel. Background Technology

[0002] With the increasing demand for space launches and the growing population density on land, the safety of rocket flight and landing zones has become increasingly prominent. Sea-based launches, by flexibly selecting launch sites and landing zones through maritime navigation, effectively address the safety issues of rocket flight paths and debris landing zones, significantly reducing the evacuation costs for personnel from land-based launch sites. Furthermore, the number of satellites with small inclinations is increasing globally, and sea-based launch platforms can move extensively across the sea, effectively overcoming the challenge of land-based launch sites in some regions failing to meet the launch requirements for satellites with inclinations of 0° to 13°. Therefore, sea-based launches are of great significance to rocket launch services and have excellent development prospects.

[0003] However, a sea launch requires both a launch ship, which serves as the rocket launch platform, and a command ship, which is located far away from the launch ship. Therefore, both the launch ship and the command ship need to sail to the launch area. However, these two ships need a lot of professional personnel for navigation, and these professionals do not participate in the rocket launch. This results in a large number of personnel required for a sea launch, and the risks faced by the two ships sailing to the launch area are also relatively high.

[0004] Therefore, how to reduce the number of personnel involved in rocket launches at sea and reduce the navigation risks of ships launching rockets at sea are technical problems that urgently need to be solved by those skilled in the art. Summary of the Invention

[0030] The lower ends of the left traction power protection device 15 and the right traction power protection device 16 are fixed to the upper surface of the base platform mounting plate 1. The left traction power protection device 15 is located behind the left fixed limiting device 2, and the right traction power protection device 16 is located behind the right fixed limiting device 3.

The upper end of another traction wire rope 13 is connected to the middle of the right rotating device 5, and the upper end of this traction wire rope 13 is located above the upper end of the right support device 8. The middle of this traction wire rope 13 is positioned above the right fixed limiting device 3, and the lower end of this traction wire rope 13 is connected to the upper end of the right traction power protection device 16. The right traction power protection device 16 drives the traction wire rope 13 to extend or shorten, thereby tightening it to pull the right rotating device 5. For example, the left traction power protection device 15 and the right traction power protection device 16 can wind the traction wire rope 13 to tighten it.

[0031] The first lifting winch 11 and the second lifting winch 12 are both mounted on the lifting beam device 6, with the second lifting winch 12 located behind the first lifting winch 11 and at a certain distance from it. The first lifting winch 11 drives multiple lifting wire ropes 14 to extend or shorten, the lower ends of which are used to connect to one side of the command vessel; the second lifting winch 12 drives another multiple lifting wire ropes 14 to extend or shorten, the lower ends of which are used to connect to the other side of the command vessel.

[0032] Based on the above, the command ship lifting device also includes: a left dynamic adjustment device 9 and a right dynamic adjustment device 10; the left dynamic adjustment device 9 is fixed to the outer side of the upper end of the left rotating device 4, and the drive part of the left dynamic adjustment device 9 is connected to the left end of the lifting beam device 6; the right dynamic adjustment device 10 is fixed to the outer side of the upper end of the right rotating device 5, and the drive part of the right dynamic adjustment device 10 is connected to the right end of the lifting beam device 6. Here, the housing of the left dynamic adjustment device 9 is fixed to the outer side of the upper end of the left rotating device 4, and the housing of the right dynamic adjustment device 10 is fixed to the outer side of the upper end of the right rotating device 5.

The rotating device mounting shaft 26 is located at the front end of the fixed crossbeam, and its extension direction is perpendicular to the extension direction of the fixed crossbeam.

The lower end of the left supporting device 7 is hinged to the supporting device mounting shaft 27. Alternatively, the supporting column can be tilted backward from bottom to top, so that more space can be provided to accommodate the left supporting device 7 after it is retracted.

[0034] Optionally, the left fixed limiting device 2 further includes: an upper limiting ear plate 24 and a lower limiting ear plate 25; wherein, the fixing device 21 further includes: a limiting column; the lower end of the limiting column is fixedly connected to the front end of the fixing crossbeam; the rear end of the upper limiting ear plate 24 is fixed to the inner and outer sides of the upper end of the supporting column, and the upper limiting ear plate 24 extends forward, thereby forming an upper limiting groove; the front end of the lower limiting ear plate 25 is fixed to the inner and outer sides of the upper end of the limiting column, and the lower limiting ear plate 25 extends backward, thereby forming a lower limiting groove; thereby limiting the rotation position of the left rotating device 4 through the upper limiting groove and the lower limiting groove. Optionally, the fixing crossbeam has a limiting groove 23 recessed downward from its upper surface, through which the lower end of the left fixed limiting device 2 and the lower end of the left supporting device 7 are accommodated.

[0035] Optional, such as Figure 3As shown, the left rotating device 4 and the right rotating device 5 have the same structure. Here, we take the left rotating device 4 as an example to introduce the structure of the left rotating device 4 and the right rotating device 5. The left rotating device 4 includes: a structural bracket 41, a traction connection hole 42, a support device mounting seat 43, a rotating mounting hole 44, a connecting device mounting seat 45, and a dynamic adjustment device mounting seat 46; the rotating mounting hole 44 is opened at the lower end of the structural bracket 41 and is used to cooperate with the rotating device mounting shaft 26, thereby realizing the hinge connection between the lower end of the left rotating device 4 and the left fixed limiting device 2; the support device mounting seat 43 is installed at the middle of the rear side of the structural bracket 41 and is used to hinge with the upper end of the left support device 7, thereby realizing the hinge connection between the left rotating device 4 and the upper end of the left support device 7; the traction connection 42 includes: a structural bracket 41, a traction connection hole 42, a support device mounting seat 43, a connecting device mounting seat 45, and a dynamic adjustment device mounting seat 46; the traction connection hole 44 is opened at the lower end of the structural bracket 41 and is used to cooperate with the rotating device mounting shaft 26, thereby realizing the hinge connection between the lower end of the left rotating device 4 and the left fixed limiting device 2; the traction connection hole 44 is opened at the lower end of the structural bracket 41 and is used to cooperate with the rotating device mounting shaft 26, thereby realizing the hinge connection between the lower end of the left rotating device 4 and the upper end of the left support device 7; the traction connection hole 44 includes: a structural bracket 41, a support device mounting seat 42, a connecting device mounting seat 43, a connecting device mounting seat 44, a connecting device mounting seat 45, and a dynamic adjustment device mounting seat 46; the traction connection hole 44 is opened at the lower end of the structural bracket 41 and is used to cooperate with the rotating The tension connection hole 42 is opened in the middle of the rear side of the structural support 41, and the tension connection hole 42 is located above the support device mounting seat 43 for connecting with the upper end of the tension wire rope 13; the connection device mounting seat 45 is installed on the inner side of the upper end of the structural support 41 for accommodating the end of the lifting beam device 6, thereby realizing the hinge connection between the lifting beam device 6 and the left rotation device 4; the dynamic adjustment device mounting seat 46 is installed on the outer side of the upper end of the structural support 41 for supporting the left dynamic adjustment device 9, thereby realizing the fixation of the left dynamic adjustment device 9 to the outer side of the upper end of the left rotation device 4.

[0036] Alternatively, the rear side of the structural support 41 protrudes rearward in the middle, and the tension connection hole 42 is located in the protruding part. Alternatively, the structural support 41 is hollow, thereby reducing the weight of the structural support 41.

[0037] Optional, such as Figure 4 As shown, the lifting beam device 6 includes: multiple triangular connecting plates 61, two rotating connecting shafts 62, and a main drive shaft 63; the main drive shaft 63 passes through one corner of the multiple triangular connecting plates 61 and is fixedly connected to the triangular connecting plates 61, and the left end of the main drive shaft 63 is hinged to the upper end of the left rotating device 4, and the right end of the main drive shaft 63 is hinged to the upper end of the right rotating device 5; the two rotating connecting shafts 62 pass through the other two corners of the multiple triangular connecting plates 61 and are rotatably connected to the triangular connecting plates 61, and the first lifting winch 11 is connected to one end of one rotating connecting shaft 62, and the second lifting winch 12 is connected to one end of the other rotating connecting shaft 62, thereby driving the two rotating connecting shafts 62 to rotate through the first lifting winch 11 and the second lifting winch 12, winding and contracting / releasing the elongating lifting wire rope 14, and completing the lifting and lowering action of the command ship.

[0038] Optionally, the left end of the main drive shaft 63 is placed on the connecting device mounting base 45 of the left rotating device 4, and passes through the upper end of the structural bracket 41 to connect with the drive part of the dynamic adjustment device mounting base 46; the right end of the main drive shaft 63 is placed on the connecting device mounting base of the right rotating device 5, and passes through the upper end of the structural bracket to connect with the drive part of the dynamic adjustment device mounting base. Optionally, the lifting beam device 6 includes four triangular connecting plates 61. Still optional, multiple lifting wire ropes 14 are evenly connected to each rotating connecting shaft 62.

[0039] like Figure 5 As shown, this application also provides a sea-launching vessel, including: a launch vessel body 110, a command vessel 120, and the aforementioned command vessel lifting device 130; the base platform mounting plate 1 of the command vessel lifting device 130 is fixed to the stern deck of the launch vessel body 110, and the front edge of the base platform mounting plate 1 faces the stern of the launch vessel body 110; the command vessel lifting device 130 lifts the command vessel 120 to the stern deck of the launch vessel body 110 or lifts it from the stern deck of the launch vessel body 110 to the sea surface.

[0040] Before launching a rocket at sea, the command ship is hoisted onto the stern deck of the launch ship using its lifting device. The launch ship then carries the command ship from the port to the launch area. Upon arrival, the command ship's lifting device lifts the command ship and lowers it onto the sea surface from the stern deck of the launch ship. Test personnel on the launch ship disembark onto the command ship using an evacuation device. The command ship then carries the test personnel away from the launch ship at sea. After reaching a safe distance, the command ship remotely monitors and directs the launch ship to launch the rocket. After the rocket launch is completed and the launch ship is confirmed to be safe, the command ship returns to the launch ship. Test team members disembark from the command ship onto the launch ship, which is then hoisted onto the stern deck of the launch ship using its lifting device before departing from the launch area.

[0041] When the command ship is on the launch ship, the left and right support devices 7 and 8 of the command ship's lifting system retract to their shortest lengths. Simultaneously, the left and right rotating devices 4 and 5 move upwards until they are flush with the upper limit lug 24. Driven by the forces of the left and right traction power protection devices 15 and 16 on the traction wire rope 13, the left and right rotating devices 4 and 5 are locked to the upper limit lug 24, increasing the overall reliability of the mechanism. At this time, the lifting beam device 6 moves to its highest position along with the left and right rotating devices 4 and 5. Figure 6 As shown.

[0042] During the preparation for lifting, the lifting wire rope 14 is gradually lowered by the lifting winches 11 and 12 on the rotating connecting shaft 62 until it can be fixedly connected to the command vessel. After the command vessel is fixedly connected to the lifting wire rope 14, the lifting winches 11 and 12 drive the rotating connecting shaft 62 to rotate, thereby raising the lifting wire rope 14 to a certain height and then stopping. Then, the left support device 7 and the right support device 8 work synchronously to extend, driving the left rotating device 4 and the right rotating device 5 to extend outward. At the same time, the left traction power protection device 15 and the right traction power protection device 16 drive the traction wire rope 13 to extend. The left support device 7, the right support device 8, the left traction power protection device 15, and the right traction power protection device 16 work synchronously, with the extension and retraction amounts being the same, providing mutual protection. This continues until the left rotating device 4 and the right rotating device 5 move to the lower limit ear plate 25. Figure 7 As shown, during this process, the sway of the launch vessel body can be adjusted by the left dynamic adjustment device 9 and the right dynamic adjustment device 10. The rotation of the main drive shaft 63 can be adjusted by the internal attitude control device, thereby adjusting the sway of the lifting beam device 6, and thus adjusting the sway of the lifting command vessel, keeping the positional relationship between the command vessel and the base platform mounting plate 1 unchanged. When the command vessel is moved to the final position, the two rotating connecting shafts 62 are driven to rotate by the left lifting winch 11 and the right lifting winch 12, thereby driving the lifting wire rope 14 to descend until the command vessel is lowered to the sea surface. The connection between the lifting wire rope 14 and the command vessel is then disconnected, completing the entire process of transferring the command vessel from the launch vessel body to the sea surface.

[0043] Once the command ship has completed its work and needs to travel from the sea to the appropriate position, it is transferred to the launch ship via the command ship's lifting device. The entire process is the reverse of the lowering procedure.

[0044] Since the command vessel of this application can be carried to the launch vessel and lowered to the sea surface from the launch vessel in the launch area, and then moved away from the launch vessel, this application can avoid the need for multiple vessels to sail, thereby reducing the number of personnel involved in the voyage, reducing the risks faced in the voyage, and reducing the cost of launching rockets at sea.
