Abstract
Description
Technical Field
[0001] This application relates to the field of aviation component packaging technology, and in particular to a packaging box for aircraft engine blades. Background Technology
[0002] Aircraft engine blades are characterized by thin-walled irregular shapes and require high precision during use. Therefore, during the transportation of these blades, strict packaging and shock absorption measures are necessary to prevent damage caused by bumps and knocks during transport.
[0003] The current packaging method for aircraft engine blades typically involves wrapping the blade surface with multiple layers of stretch film, and then placing multiple blades in a box filled with flexible materials (such as shock-absorbing foam) for packaging and transportation. While this method can prevent the blades from being damaged by impacts, the blades are not fixed to the flexible material and there are gaps inside. As a result, the blades can still shake and roll during transportation, posing a risk of blade damage. Utility Model Content
[0004] Therefore, it is necessary to provide a packaging box for aero-engine blades that can prevent them from shaking during transportation and avoid damage to the blades.
[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:
[0006] An aircraft engine blade packaging box is provided for packaging and positioning aircraft engine blades. The aircraft engine blade packaging box includes a box body, a supporting cardboard unit, and a positioning cardboard unit. The box body has a receiving cavity. The supporting cardboard unit is disposed in the receiving cavity and includes a first supporting cardboard and a second supporting cardboard. The first supporting cardboard and the second supporting cardboard are perpendicular to each other and interlock with each other, dividing the receiving cavity into at least four independent receiving spaces for accommodating the blades.
[0007] The limiting cardboard unit is configured in multiple ways, and each limiting cardboard unit includes a first limiting cardboard and at least two second limiting cardboards. The first limiting cardboard and at least two second limiting cardboards are spaced apart along the length direction of the box. The first limiting cardboard has a first clearance groove and at least two first slots on one side of the box height direction. The first clearance groove is used to avoid and engage the first supporting cardboard. Each first slot corresponds to one accommodating space. The at least two first slots are used to engage the blades in the multiple accommodating spaces arranged in the width direction of the box. Each second limiting cardboard has a second clearance groove and at least two second slots on the side of the box height direction away from the first slot. The second clearance groove is used to avoid and engage the first supporting cardboard. Each second slot corresponds to one accommodating space. The at least two second slots are used to engage the blades in the multiple accommodating spaces arranged in the width direction of the box.
[0008] The first limiting cardboard is disposed between at least two second limiting cardboards, and in the height direction of the box, the direction in which the first slot engages the blade is opposite to the direction in which the second slot engages the blade.
[0009] Understandably, this application, by setting up a supporting cardboard unit and a limiting cardboard unit including a first limiting cardboard and a second limiting cardboard, divides the accommodating cavity into at least four accommodating spaces to accommodate the blade. The first limiting cardboard and at least two second limiting cardboards respectively engage the blade from both sides along the height direction of the box, positioning the blade at least at three points. Simultaneously, by combining the first limiting cardboard, the second limiting cardboard, and the first supporting cardboard, the supporting cardboard unit, the limiting cardboard unit, and the blade can be connected into a single unit. This ensures the blade is stably fixed within the box, preventing it from shaking or rolling, and avoiding deformation due to collisions during transportation.
[0010] In one embodiment, the receiving cavity has an opening in the height direction of the housing, the opening of the first slot faces opposite to the opening, and the opening of the second slot faces the same direction as the opening. Thus, the first and second limiting cardboard pieces engage and limit the blade from two different directions, further improving the positioning effect of the blade.
[0011] In one embodiment, the first slot is V-shaped, and the inner diameter of the first slot gradually decreases along the height of the box and from bottom to top.
[0012] In one embodiment, the second slot is U-shaped.
[0013] In one embodiment, the first support cardboard is provided with a third clearance groove and a fourth clearance groove, the third clearance groove being provided corresponding to the first clearance groove, and the fourth clearance groove being provided corresponding to the second clearance groove;
[0014] The first limiting cardboard engages with the first supporting cardboard through the cooperation of the first clearance groove and the third clearance groove; the second limiting cardboard engages with the first supporting cardboard through the cooperation of the second clearance groove and the fourth clearance groove.
[0015] In one embodiment, the first support cardboard is provided as multiple pieces, which are spaced apart along the width direction of the box to divide the accommodating cavity into multiple first subspaces in the width direction of the box.
[0016] In one embodiment, the second support cardboard is provided in multiple pieces, which are spaced apart along the length of the box to divide the accommodating cavity into multiple second subspaces in the width of the box.
[0017] In one embodiment, both the first and second support paperboards are configured as corrugated paperboard or honeycomb paperboard.
[0018] In one embodiment, both the first limiting cardboard and the second limiting cardboard are configured as corrugated cardboard or honeycomb cardboard.
[0019] In one embodiment, along the height direction of the housing, at least two layers of supporting cardboard units are provided in the accommodating cavity, the at least two layers of supporting cardboard units are stacked, and each layer of supporting cardboard unit divides the accommodating cavity into at least four independent accommodating spaces for accommodating the blade.
[0020] Understandably, by setting up at least two layers of supporting cardboard units to stack, at least eight accommodating spaces can be formed to accommodate aircraft engine blades, thereby increasing the number of aircraft engine blades that the aircraft engine blade packaging box can hold.
[0021] Compared with existing technologies, the aero-engine blade packaging box described in this application, by setting up a supporting cardboard unit and a limiting cardboard unit including a first limiting cardboard and a second limiting cardboard, divides the accommodating cavity into at least four accommodating spaces to accommodate the blade. The first limiting cardboard and at least two second limiting cardboards respectively engage the blade from both sides in the height direction of the box, positioning the blade at at least three points. Simultaneously, by combining the first limiting cardboard, the second limiting cardboard, and the first supporting cardboard, the supporting cardboard unit, the limiting cardboard unit, and the blade can be connected into a single unit. This ensures the blade is stably fixed within the box, preventing it from shaking or rolling, and avoiding deformation due to collisions during transportation. Attached Figure Description

[0035] Please see Figures 1 to 4This application provides an aircraft engine blade packaging box 100, which is used to package and fix multiple aircraft engine blades 200 to prevent the blades 200 from shaking or rolling during transportation.
[0036] Specifically, the aircraft engine blade packaging box 100 includes a box body 10, a supporting cardboard unit 20, and a limiting cardboard unit 30. The box body 10 has a receiving cavity 11. The supporting cardboard unit 20 is disposed in the receiving cavity 11 and includes a first supporting cardboard 21 and a second supporting cardboard 22. The first supporting cardboard 21 and the second supporting cardboard 22 are perpendicular to each other and interlocked, dividing the receiving cavity 11 into at least four independent receiving spaces 111 for accommodating the blade 200. Multiple limiting cardboard units 30 are configured, and each limiting cardboard unit 30 includes a first limiting cardboard 31 and at least two second limiting cardboards 32. The first limiting cardboard 31 and at least two second limiting cardboards 32 are spaced apart along the length x direction of the box body 10. The first limiting cardboard 31 has a first clearance groove 311 and at least two first locking grooves 312 on one side of the height z direction of the box body 10. The first clearance groove 311 is used to clearance and lock the blade 200. A supporting cardboard 21, each first slot 312 corresponds to a receiving space 111, and at least two first slots 312 are used to engage the blades 200 within the multiple receiving spaces 111 arranged in the width direction y of the box body 10; each second limiting cardboard 32 has a second clearance groove 321 and at least two second slots 322 on the side of the box body 10 in the height direction z and away from the first slots 312; the second clearance groove 321 is used to avoid and engage the first supporting cardboard 21, each second slot 322 corresponds to a receiving space 111, and at least two second slots 322 are used to engage the blades 200 within the multiple receiving spaces 111 arranged in the width direction y of the box body 10; wherein, the first limiting cardboard 31 is located between at least two second limiting cardboard 32, and in the height direction z of the box body 10, the direction in which the first slot 312 engages the blades 200 is opposite to the direction in which the second slot 322 engages the blades 200.
[0037] It needs to be explained that in existing technologies, the blade surface is first wrapped with multiple layers of stretch film, and then multiple blades are placed in a packaging box filled with flexible materials such as shock-absorbing foam for packaging and transportation. Since the blades are not secured to the flexible material, they will still shake and roll during transportation, and there is still a risk of collision deformation due to shaking and rolling. Furthermore, wrapping with stretch film and then placing in flexible material is inefficient, and because the flexible material needs to be of a certain thickness to effectively prevent collisions, the packaging cost is high. In this application, by setting a supporting cardboard unit 20 and a limiting cardboard unit 30 including a first limiting cardboard 31 and a second limiting cardboard 32, the supporting cardboard unit 20 divides the accommodating cavity 11 into at least four accommodating spaces 111 to accommodate the blade 200. The first limiting cardboard 31 and at least two second limiting cardboards 32 respectively engage the blade 200 from both sides of the box 10 in the height direction z, thus positioning the blade 200 at least at three points. Simultaneously, by combining the first limiting cardboard 31, the second limiting cardboard 32, and the first supporting cardboard 21, the supporting cardboard unit 20, the limiting cardboard unit 30, and the blade 200 can be connected into a whole. This ensures that the blade 200 is stably fixed within the box 10, preventing the blade 200 from shaking or rolling, and avoiding deformation due to collisions during transportation. Furthermore, fixing the aero-engine blade 200 with cardboard eliminates the need for a cumbersome winding process, resulting in higher packaging efficiency, and the cardboard material cost is relatively low.
[0038] like Figures 1 to 3 As shown, the accommodating cavity 11 has an opening 112 in the height direction z of the box body 10. The opening of the first slot 312 is oriented opposite to the orientation of the opening 112, and the opening of the second slot 322 is oriented the same as the orientation of the opening 112.
[0039] In this embodiment, the opening 112 faces upwards in the height z direction of the box body 10. Therefore, the opening of the first slot 312 faces downwards, and the opening of the second slot 322 faces upwards. Thus, there are limiting cardboard pieces at both the top and bottom of the box body 10 in the height z direction for limiting movement.
[0040] In one embodiment, along the height direction z of the housing 10, at least two layers of stacked support cardboard units 20 are disposed within the accommodating cavity 11, and each layer of support cardboard unit 20 divides the accommodating cavity 11 into at least four independent accommodating spaces 111 for accommodating the blades 200. Thus, by providing at least two layers of stacked support cardboard units 20, at least eight accommodating spaces 111 are formed for accommodating the aircraft engine blades 200, thereby increasing the number of aircraft engine blades 200 that the aircraft engine blade packaging box 100 can accommodate.
[0041] Here, the number of layers supporting the cardboard unit 20 can be two, three, four, etc.
[0042] It should be explained that when only one layer of support cardboard unit 20 is needed, the number of support cardboard units 20 can also be one layer.
[0043] In one embodiment, multiple first support cardboard pieces 21 are provided, and these pieces are spaced apart along the width direction y of the housing 10 to divide the accommodating cavity 11 into multiple first sub-spaces 213 in the width direction y of the housing 10. Here, the number of first support cardboard pieces 21 can be configured as two, three, four, etc. When the number of first support cardboard pieces 21 is configured as four, the accommodating cavity 11 can be divided into five first sub-spaces 213 in the width direction y of the housing 10. It is understood that when two first sub-spaces 213 are needed, the number of first support cardboard pieces 21 can also be configured as one.
[0044] Furthermore, the first supporting cardboard 21 is provided with a third clearance groove 211 and a fourth clearance groove 212. The third clearance groove 211 is correspondingly provided with the first clearance groove 311, and the fourth clearance groove 212 is correspondingly provided with the second clearance groove 321. The first limiting cardboard 31 engages with the first supporting cardboard 21 through the cooperation of the first clearance groove 311 and the third clearance groove 211. The second limiting cardboard 32 engages with the first supporting cardboard 21 through the cooperation of the second clearance groove and the fourth clearance groove 212. Thus, by providing the third clearance groove 211 and the fourth clearance groove 212, not only can the first limiting cardboard 31 and the second limiting cardboard 32 engage with the first supporting cardboard 21 respectively, but the first limiting cardboard 31 and the second limiting cardboard 32 can also be flush with the first supporting cardboard 21 in the height direction z of the box body 10.
[0045] like Figures 1 to 4 As shown, multiple second support cardboard pieces 22 are arranged at intervals along the length x of the box 10 to divide the accommodating cavity 11 into multiple second sub-spaces 221 in the width y of the box 10. The number of second support cardboard pieces 22 can be configured as two, three, four, etc. For example, when the number of second support cardboard pieces 22 is configured as three, the accommodating cavity 11 can be divided into four second sub-spaces 221 in the width y of the box 10. It can be understood that when only two second sub-spaces 221 are needed, the number of second support cardboard pieces 22 can also be configured as one.
[0046] Furthermore, by combining the first support cardboard 21, the receiving cavity 11 can be divided into multiple rows of receiving spaces 111, thereby accommodating and positioning the blade 200.
[0047] Here, both the first support cardboard 21 and the second support cardboard 22 are configured as corrugated cardboard or honeycomb cardboard. Corrugated cardboard or honeycomb cardboard has good cushioning performance and structural strength, which can effectively reduce the breakage rate of the blade 200 during transportation.
[0048] In one embodiment, the number of first slots 312 on each first limiting cardboard 31 is the same as the number of first subspaces 213. Each first limiting cardboard 31 can be simultaneously fixed to a row of blades 200 arranged in the width direction of the housing 10 (see reference). Figure 3 ).
[0049] Furthermore, the first slot 312 is V-shaped, and its inner diameter gradually decreases from bottom to top along the height of the housing 10. Thus, by setting the first slot 312 in a V-shape, it can accommodate blades 200 of different widths. When the blade 200 is wider, it can be engaged closer to the top of the V-shape; when the blade 200 is narrower, it can be engaged closer to the bottom of the V-shape. This provides good fixation for blades 200 of different widths.
[0050] In one embodiment, each second limiting cardboard 32 is provided with a plurality of second slots 322, wherein the number of second slots 322 on each second limiting cardboard 32 is the same as the number of first subspaces 213.
[0051] Furthermore, the second slot 322 is arranged in a "U" shape.
[0052] In this embodiment, two second slots 322 on two second limiting cardboards 32 located in the same accommodating space 111 are used to limit the head 210 and tail 220 of the blade 200, respectively. A first limiting cardboard 31 is located between the two second limiting cardboards 32 and is used to limit the middle 230 of the blade 200. Thus, limiting cardboards are used to limit the blade from the head 210, tail 220, and middle 230.
[0053] Furthermore, both the first limiting cardboard 31 and the second limiting cardboard 32 are configured as corrugated cardboard or honeycomb cardboard. Corrugated cardboard or honeycomb cardboard has good cushioning performance and structural strength, which can effectively reduce the breakage rate of the blade 200 during transportation.
[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0055] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
