[0027] For those skilled in the art, the present invention can be implemented without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0028] Figure 1This is a schematic diagram of a carrier rocket hoisting protection device according to one embodiment of the present utility model; Figure 2 This is an exploded view of a lifting protection device for a carrier rocket according to one embodiment of the utility model; Figure 3 The utility model is a schematic diagram of the installation of a lifting protection device for a carrier rocket according to an embodiment of the present invention.

[0029] like Figure 1 and Figure 3 As shown, the utility model provides a lifting and protection device for a carrier rocket, comprising: a strap 101, which is a stainless steel thin plate; clips 102, which are arranged at both ends of the strap 101 and are used to fix the strap 101 on the carrier rocket; a first pad 103 and a second pad 104, which are installed on the inner side of the strap 101 and are respectively used to be arranged on both sides of the protrusion of the arrow wall of the carrier rocket.

[0030] Specifically, if Figure 3 As shown, protrusions such as cryogenic pipelines or pressurized delivery pipelines are often installed on the outer wall of a launch vehicle. During the lifting process, the risk of damage to such protrusions by the lifting belt must be considered. The use of a lifting protection device can increase the reliability and safety of the lifting. The stainless steel sheet wrapping strap 101 used in this application is wrapped around the launch vehicle body to prevent the lifting belt from directly applying force to the launch vehicle body. In other words, the wrapping strap 101 disperses the force.

[0031] During the specific operation, the first pad 103 and the second pad 104 are respectively set on both sides of the protrusion of the rocket body, and then the wrapping belt 101 is wrapped around the first pad 103 and the second pad 104 and the rocket body. The wrapping belt 101 can be fixed on the rocket body according to the size of the rocket body through the clip 102.

[0032] The hoisting protection device in this embodiment can be used in a hanging basket type hoisting method, which can eliminate the end shaft neck installation structure, reduce the weight of the rocket body structure, and thus increase the carrying capacity of the carrier rocket.

[0033] like Figure 2 As shown, according to one embodiment of the present invention, the lifting protection device of the launch vehicle also includes: a first ear plate 105 and a second ear plate 106, which are arranged on one side of the width direction of the wrapping belt 101 and are used to fix the first pad 103 and the second pad 104.

[0034] According to one embodiment of the present invention, the first ear plate 105 and the second ear plate 106 extend toward the inner side of the strap 101 .

[0035] According to one embodiment of the present invention, the first ear plate 105 and the first cushion block 103 are provided with multiple through holes correspondingly, the second ear plate 106 and the second cushion block 104 are provided with multiple through holes correspondingly, and the first cushion block 103 and the second cushion block 104 are fixed by passing the core shaft through the through holes.

[0036] According to one embodiment of the present invention, the first cushion block 103 and the second cushion block 104 are arc-shaped, wherein the inner arc matches the size of the outer wall of the launch vehicle, and the outer arc and the inner arc are concentric.

[0037] According to an embodiment of the present invention, the lifting protection device of the launch vehicle further includes: third ear plates 107, which are evenly arranged on both sides of the wrapping belt 101 in the width direction for limiting the lifting belt.

[0038] According to one embodiment of the present invention, the third ear plate 107 extends toward the outside of the strap 101 .

[0039] According to one embodiment of the present invention, the lifting protection device of the launch vehicle further includes: a handle 108, which is arranged on the outer side of the strap 101 for the operator to grasp.

[0040] According to an embodiment of the present invention, the clip 102 is a toggle-type door clip, and the toggle-type handle and the latch hook are respectively mounted on the two ends of the strap 101 by rivets.

[0041] According to one embodiment of the present invention, the handle 108 and the clip 102 are mounted on the strap 101 via a bottom plate 109 provided on the strap 101 .

[0042] Specifically, to prevent the first and second pads 103 and 104 from moving below the strap 101 on either side of the rocket's arrowhead projection, a first lug 105 and a second lug 106 are provided on one side of the strap 101 in the width direction, corresponding to the first and second pads 103 and 104. The first and second lugs 105 and 106 are folded inwardly of the strap 101, i.e., toward the arrowhead. Through-holes corresponding to the through-holes or openings in the pads are provided in the folded portion. A mandrel passes through the through-holes of the first and second lugs and the openings / through-holes of the first and second pads, respectively, securing the first lug 105 to the first pad 103, and the second lug 106 to the second pad 104.

[0043] In one embodiment, the outer shapes of the first and second pads 103 and 104 are designed based on the arc shape of the launch vehicle's rocket body. If the launch vehicle is covered with a foam layer, the inner arc must match the dimensions of the launch vehicle's rocket body foam layer, and the outer and inner arcs must be concentric. The hoisting protection device of the present application can prevent circumferential frictional deformation of the thermal insulation foam layer during tensioning when the lifting strap is in direct contact with the launch vehicle body. Specifically, the strap isolates the frictional forces during the lifting strap tensioning process.

[0044] To limit the position of the sling, third lugs 107 can be provided on both sides of the strap 101 in the width direction, and evenly spaced along the length of the strap 101. In one embodiment, the strap 101 is evenly spaced along the half circumference of the arrow body, and the third lugs 107 are folded toward the outside of the strap 101, i.e., toward the outside of the arrow body.

[0045] It should be noted that the base plate 109 is provided to enhance the rigidity of the strap 101 during installation with the handle 108 and the clip 102, thereby preventing the lifting protection device from bending or deforming during use. In one embodiment, three different sizes of base plates 109 can be provided, depending on the different mounting structures of the handle 108 and the clip 102, all of which are provided with rivet holes for easy installation.

[0046] For example, the handle 108 facilitates gripping during installation of the strap 101 and facilitates positioning of the clip 102. The handle 108 consists of two lugs and a handle. The lugs are provided with multiple rivet holes corresponding to the surface where they connect to the strap 101, through which the lugs are secured. The clip 102 utilizes a toggle-type door buckle, consisting of a toggle handle and a latch hook. The toggle handle and latch hook are attached to each end of the strap 101 via rivets. By operating the handle, the latch hook is tightened, tightening the latch hook, causing the strap 101 to tighten against the outer wall of the hull, thus preparing the sling for installation.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
