DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0023] Existing lifting beams are generally suitable for lifting ordinary conventional goods, but when it comes to irregular heavy objects, the lifting is limited because the center of gravity cannot be accurately found, and the length of the lifting beam cannot be automatically adjusted according to the size of large goods, causing the heavy objects to tilt during the lifting process and causing accidents. The center of gravity of non-cylindrical sleeves such as trapezoidal rocket barrels is not at the center point during transportation;

[0024] In view of this, the utility model provides a flipping device for a rocket sub-stage. Through the cooperation of a first sling, main reinforcement ribs, auxiliary reinforcement ribs, a main beam, a slider, a second sling, a lifting ear, a limit rod, a fixing frame, a connecting piece, an adjusting screw, a moving block and a fixed shaft, the lifting position can be changed, so that the distance between the slings can be changed according to different needs. At the same time, the center of gravity of the lifting position can also be changed, thereby avoiding the shaking phenomenon. The auxiliary reinforcement structure reinforces the universal adjustable lifting beam to avoid the occurrence of cracking, thereby ensuring safe use.

[0025] Embodiment 1: Figure 1 , 2, 3, 4, 5, 6, 7, 8 and 9 show that a turning device for a rocket sub-stage comprises a main reinforcing rib 2, both sides of the main reinforcing rib 2 are provided with reinforcing bushings 7, the two reinforcing bushings 7 are provided with a first sling 1, a slider 4 is slidably connected to the lower part of the main reinforcing rib 2, the inner walls of the two sliders 4 are slidably connected to a main beam 3 fixedly connected to the bottom of the main reinforcing rib 2, a second sling 5 is provided to the lower part of the two sliders 4, the main reinforcing rib 2 is processed with a plurality of shackles 6, and the two second slings 5, the inner walls of the two lifting ears 9 are movably connected with fixed shafts 15, the outer walls of the two fixed shafts 15 are installed with moving blocks 14, the inner walls of the two moving blocks 14 are movably connected with adjusting screws 13, the outer walls of the two adjusting screws 13 are rotatably connected with vertical rods 17 through bearings, the tops of the two vertical rods 17 are installed with connecting pieces 12, the outer walls of the two connecting pieces 12 are installed with fixing frames 11, and the ends of the two adjusting screws 13 are installed with sealing plates 16;

[0026] In the specific implementation process, it is worth pointing out that the material of the main reinforcement 2 can be Q355 main reinforcement, etc., the material of the reinforcement bushing 7 can be 30CrMnSiA bushing, etc., the material of the main beam 3 can be Q355 H-shaped steel, etc., the material of the slider 4 can be 30CrMnSiA slider, etc., and the specific materials of all the components thereon are not restricted as long as they meet the use requirements. The staff can choose according to the actual use requirements, and the shackle 6 is a 4.75t shackle, and the first sling 1 is 2 ring slings with a load of 4t and a length of 2m. , the second sling 5 is 2 ring-shaped slings with a load of 4t and a length of 2m, and is connected to the bottom of the slider 4 through a 4.75t bow-shaped shackle, and the turning device of the rocket sub-stage includes a turning sling including 1 set of universal lifting beams (the universal lifting beam is the main beam 3), 1 set of first-stage tail section turning slings, 1 set of first- and second-stage inter-stage turning slings, 1 set of second-stage tail section turning slings, 1 set of second- and third-stage inter-stage turning slings, 1 set of third-stage tail section turning slings, 1 set of third- and fourth-stage inter-stage turning slings, and 1 set of fourth-stage turning slings. The universal lifting beam adopts a tripod double sling structure, which can realize the lifting and turning of different cabin sections;

[0027] Furthermore, the outer wall of the main reinforcing rib 2 is provided with a plurality of auxiliary reinforcing ribs 8;

[0028] In the specific implementation process, it is worth pointing out that the multiple auxiliary reinforcing ribs 8 can assist the main reinforcing ribs 2 to improve the strength of the main beam 3;

[0029] Furthermore, the outer walls of the two fixing frames 11 are both installed with rubber pads, and the two fixing frames 11 are both processed with openings;

[0030] In the specific implementation process, it is worth pointing out that the staff can connect and fix the fixing frame 11 with the external rocket compartment by using fixing bolts through the opening, and can connect and fix rocket compartments of different specifications by replacing fixing frames 11 of different specifications, and the rubber pad can improve the connection tightness between the fixing frame 11 and the external rocket compartment;

[0031] Furthermore, limit blocks are installed on both sides of the main beam 3, and the main beam 3 and the two sliders 4 are processed with openings;

[0032] In the specific implementation process, it is worth pointing out that the staff can connect and fix the slider 4 and the main beam 3 through the opening using external fixing bolts, thereby ensuring the stability of the rocket sub-stage flipping device when in use;

[0033] Furthermore, one side of the two lifting ears 9 is rotatably connected to the limit rod 10 through a pin shaft;

[0034] In the specific implementation process, it is worth pointing out that a damping pad should be installed at the connection between the limit rod 10 and the lifting ear 9, so as to increase the friction between the limit rod 10 and the lifting ear 9, and the limit rod 10 can limit the fixed shaft 15 and the lifting ear 9. When in use, the staff twists the limit rod 10 clockwise. When the limit rod 10 rotates to a certain angle, the fixed shaft 15 can be inserted into the inner wall of the lifting ear, and then the fixed shaft 15 is pushed to the bottom of the lifting ear 9. At this time, the limit rod 10 is pushed back to its original position, and because the bottom of the limit rod 10 is engaged with the bottom of the lifting ear 9, when the fixed shaft 15 moves upward, the limit rod 10 cannot rotate counterclockwise, so the limit rod 10 can limit the fixed shaft 15.

[0035] Specifically, when using the flipping device of the rocket sub-stage, the staff first adjusts the position of the slider 4 on the surface of the main beam 3 according to the use requirements. After the adjustment is completed, the slider 4 and the main beam 3 are installed and fixed with fixing bolts. Then the staff connects the fixing frame 11 to the external rocket compartment, and then installs the fixed shaft 15 and the lifting ear 9. Then it can be used. When the transportation center of gravity needs to be adjusted, the staff twists the adjusting screw 13. At this time, the adjusting screw 13 can drive the vertical rod 17 to move along the outer wall of the moving block 14. At this time, the center of gravity height of the rocket compartment can be changed. When it is transported to the appropriate position, the staff can flip the rocket compartment.

[0036] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
