Description

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] like Figures 1-3 As shown, a rocket stabilizing device includes: a fixing frame 20, a fastening mechanism 30, and a strap 10. The fixing frame 20 includes a fixing frame body 21 with an opening, and the fixing frame body 21 has a limiting arc surface 22 adapted to the outer diameter of the rocket body, and the limiting arc surface 22 is arranged on a minor arc with the rocket body axis as the center. Because the limiting arc surface 22 is arranged on a minor arc with the rocket body axis as the center, the rocket stabilizing device can be engaged with the rocket body from the side of the rocket body and can be detached from the side of the rocket body.

[0042] The fastening mechanism 30 is located at the end of the limiting arc surface 22 and is fixedly connected to the fixed frame 21.

[0043] The strap 10 is positioned at the opening of the fixing frame 20, and its end is fixedly connected to the fastening mechanism 30. The fastening mechanism 30 is configured to adjust the length of the strap 10 to secure the arrow body within the area enclosed by the strap 10 and the fixing frame 20. The strap 10 is preferably made of a flexible material with tensile strength, which can bind and limit the arrow body while providing better fit and self-adaptability.

[0044] The fastening mechanism 30 includes a fastening frame 31 and a first tensioning member 33 for adjusting the length of the strap 10. One end of the first tensioning member 33 is fixedly connected to the strap 10, and the other end is fixedly connected to the fastening frame 31.

[0045] Preferably, the fastening mechanism 30 has two parts, which are fixed to both ends of the fixed frame 21.

[0046] The first tensioning member 33 is preferably a turnbuckle. Furthermore, other mechanical structures that can adjust the distance between connection points by self-adjustment are also applicable to this invention, such as ball screw structures, multi-link mechanisms, and worm gears.

[0047] In another embodiment of the present invention, the fastening mechanism 30 further includes a guide rod for guiding the strap 10. The guide rod is arranged parallel to the arrow body and is fixedly or rotatably connected to the fastening frame 31. The guide rod guides the strap 10, thereby controlling the connection position between the strap and the fastening mechanism 30, making the force distribution more reasonable. Simultaneously, the guide rod controls the position of the strap 10 near the fastening mechanism 30, ensuring that the strap 10 has a better enveloping effect on the arrow body, ensuring the contact area between the arrow body and the strap 10, and controlling the pressure between the strap 10 and the arrow body within a reasonable range. In other embodiments of the present invention, the connection between the strap 10 and the fastening mechanism 30 can be achieved without the guide rod, and the radial direction of the arrow body can be limited by the combination of the strap 10 and the fastening mechanism 30.

[0048] When the guide rod is fixedly connected to the fastening frame 31, the strap 10 can slide along the surface of the guide rod, realizing relative movement between the guide rod and the fastening frame 31. When the guide rod is rotatably connected to the fastening frame 31, the strap 10 moves along its length direction by means of its rotation.

[0049] Preferably, the guide rods include a first guide rod 32 and a second guide rod 35 arranged parallel to each other. The second guide rod 35 is positioned close to the arrow body, and the strap 10 passes through the space between the second guide rod 35 and the arrow body, as well as between the first guide rod 32 and the second guide rod 35. The strap 10 is tangentially positioned to both the first guide rod 32 and the second guide rod 35. The second guide rod 35, positioned close to the arrow body, guides the strap 10 closer to the arrow body at the connection point between the strap 10 and the fastening mechanism 30, maximizing the contact area between the strap 10 and the arrow body and reducing the pressure on the contact surface between the arrow body and the strap 10. The distance between the first guide rod 32 and the arrow body is greater than the distance between the second guide rod 35 and the arrow body, and this distance is controlled at a reasonable position. This ensures that the strap 10, guided by the first guide rod 32, is positioned more appropriately at the connection point with the fastening mechanism 30, guaranteeing the bonding strength at the connection point and preventing excessive concentration of stress.

[0050] In addition, the fixed frame 21 also includes a lifting through hole 36 for the lifting component to pass through. The lifting through hole 36 is arranged parallel to the axial direction of the rocket body. The lifting through hole 36 allows the lifting component to pass through it and limits its width. When the rocket body tilts to the side, it limits the tilting and effectively prevents the rocket body from overturning during the lifting process.

[0051] As another embodiment of the present invention, it further includes a second tensioning member 34 for fixing the rocket stabilizing device and the rocket erecting device radially to the rocket body, and a third tensioning member (not shown) for fixing the rocket stabilizing device and the rocket erecting device axially to the rocket body. The second tensioning member 34 is used to secure the mechanism to the rocket erecting device radially to the rocket body, and the third tensioning member is used to secure the mechanism to the rocket erecting device axially to the rocket body.

[0052] like Figures 4-7 As shown, a lifting system includes the aforementioned rocket stabilizing device 500, a lifting device 100, a lifting component 300, and a pallet 400. The pallet 400 is fixed to the bottom end of the rocket body 200 by means of screws or other detachable fixing methods. The lifting component 300 is disposed between the lifting device 100 and the pallet 400; one end of the lifting component 300 is fixedly connected to the lifting device 100, and the other end is fixedly connected to the pallet 400. Simultaneously, the lifting component 300 passes through the lifting through hole 36, penetrating the rocket stabilizing device 500.

[0053] The lifting component 300 includes a load-bearing lifting component and an adjusting lifting component 330. The load-bearing lifting component includes a first load-bearing lifting component 310 and a second load-bearing lifting component 320, with the line connecting the first and second load-bearing lifting components 310 and 320 located on one side of the axis of the rocket body 200. The adjusting lifting component 330 is located on the other side of the axis of the rocket body 200. The length of the adjusting lifting component 330 is adjustable, allowing for adjustments to the verticality and center of gravity of the rocket body 200.

[0054] The first load-bearing lifting member 310 and the second load-bearing lifting member 320 are preferably lifting rods, chains, or lifting wire ropes.

[0055] The adjusting lifting component 330 is preferably a lifting rod, chain, or wire rope equipped with a telescopic structure. The telescopic structure is preferably a hand-operated hoist.

[0056] Preferably, the distance between the line connecting the first bearing member 310 and the second bearing member 320 and the axis of the arrow body 200 is 100mm. Within this distance range, the first bearing member 310 and the second bearing member 320 can provide good support for the arrow body 200. At the same time, when adjusting the adjusting member 330, the center of gravity of the arrow body 200 can be well controlled.

[0057] In one embodiment of the present invention, the supporting lifting member includes an upper lifting member 301, a lower lifting member 303, and a connecting member 302. One end of the connecting member 302 is fixedly connected to the upper lifting member 301, and the other end of the connecting member 302 is fixedly connected to the lower lifting member 303. The connecting member 302 is disposed at the position of the rocket stabilizing device 500 and inserted into the lifting through hole 36, thereby enabling the supporting lifting member to penetrate through the rocket stabilizing device 500. The connection member 302 facilitates the installation of the supporting lifting member, especially the installation at the position of the rocket stabilizing device 500, and avoids situations where the supporting lifting member has connection points that cannot be penetrated.

[0058] Preferably, the connector 302 is a long strip structure made of a rigid material capable of supporting the arrow body 200.

[0059] In addition, the lifting rods, chains, or wire ropes other than the 330 telescopic structure of the lifting component can also be connected by upper lifting components, lower lifting components, and connecting components. The principle and function are the same as those of the load-bearing lifting components, and will not be elaborated here.

[0060] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
