[0071] Figure 1 A schematic diagram of the three-dimensional structure of a loading device 100 in an embodiment of the present application is shown; Figure 2 A schematic diagram of the exploded structure of a loading device 100 in an embodiment of the present application is shown; Figure 3 The schematic diagram of the structure of the loading device 100 in one embodiment of the present application is shown, in which the first target part 200 and the second target part 300 are loaded; for the convenience of explanation, only the contents related to the embodiment of the present application are shown. Figure 3 In order to facilitate the illustration of the parts where the first target part 200 , the second target part 300 and the loading device 100 cooperate with each other, part of the structure of the first target part 200 and the second target part 300 is removed.

[0072] Please refer to Figures 1 to 3 , an embodiment of the present application provides a loading device 100, which is used to load a first target part 200 and a second target part 300 along a first direction F1. The first target part 200 is provided with a first axial hole, and the second target part 300 is provided with a second axial hole. The first target part 200 and the second target part 300 are detachably connected. Exemplarily, the sides of the first target part 200 and the second target part 300 opposite to each other can be detachably connected by means of a bolt structure. The first axial hole and the second axial hole are opened along the first direction F1. The loading device 100 includes a base 110, a support member 120 and a hoisting member 130.

[0073] The base 110 is the main bearing component in the loading device 100. The base 110 can be constructed to be roughly plate-shaped. The base 110 has a bearing surface m for bearing the first target part 200 and the second target part 300. Specifically, the first target part 200 and the second target part 300 are placed on the bearing surface m of the base 110 in sequence along the first direction F1, forming a structure in which the base 110, the first target part 200 and the second target part 300 are stacked along the first direction F1. In the embodiment of the present application, the first direction F1 is a vertical direction.

[0074] The support member 120 is a component in the loading device 100 that cooperates with the base 110 for loading the first target member 200 and the second target member 300. The support member 120 includes a support body 121, a first support portion 122 arranged around the support body 121, and a second support portion 123 arranged around the support body 121. The first support portion 122 and the second support portion 123 are arranged in sequence along the first direction F1. The support body 121 is used to penetrate the first axial hole and the second axial hole along the first direction F1, the first support portion 122 is used to support the first target member 200 and be detachably connected to the first target member 200, and the second support portion 123 is used to support the second target member 300 and be detachably connected to the second target member 300. Exemplarily, the first support portion 122 and the first target member 200 can be detachably connected by means of a bolt structure, and the second support portion 123 and the second target member 300 can be detachably connected by means of a bolt structure.

[0075] The supporting body 121 is generally a longitudinal member extending along the first direction F1. The first supporting portion 122 and the second supporting portion 123 can be generally arranged in an annular shape. It can be understood that the outer contour of the first supporting portion 122 can be adapted to the hole wall of the first axial hole of the first target part 200, and the outer contour of the second supporting portion 123 can be adapted to the hole wall of the second axial hole of the second target part 300, as long as the radial positioning of the first target part 200 and the second target part 300 can be achieved, and no specific limitation is made here.

[0076] The supporting body 121, the first supporting portion 122 and the second supporting portion 123 can be an integral structure or a split structure. An integral structure refers to a structure formed by connecting two components into a whole, and the two components are no longer two independent components. For example, the connection method between the supporting body 121 and the first supporting portion 122 can be welding, hot melt welding or integral molding. Integral molding refers to a component formed as an integral whole by an integral molding process using the same material. A split structure refers to a structure formed by two components fixedly connected by related connecting parts. It can be selected according to the specific usage situation and is not specifically limited here.

[0077] The hanging member 130 is a component used to cooperate with the supporting member 120. The relevant lifting device hangs the loading device 100 with the help of the hanging member 130. The hanging member 130 is detachably connected to the end of the supporting body 121 away from the base 110. For example, the hanging member 130 can be detachably connected to the end of the supporting body 121 away from the base 110 by threaded connection. Of course, other detachable connection methods are also possible, and are not specifically limited here.

[0078] Therefore, by providing the base 110, the base 110 can be used to carry the first target part 200 and the second target part 300. By providing the support member 120 on the base 110, the support member 120 can be used to sequentially penetrate the first axial hole of the first target part 200 and the second axial hole of the second target part 300, so that the first support part 122 of the support member 120 can support the first target part 200, and the second support part 123 of the support member 120 can support the second target part 300. At the same time, the first support part 122 and the first target part 200 can be detachably connected, and the second support part 123 and the second target part 300 can be detachably connected, so that the radial direction of the first target part 200 can be limited and the radial direction of the second target part 300 can be limited. By providing a detachable hanging member 130 at one end of the supporting body 121 of the supporting member 120 away from the base 110, the loading device 100 can be hung to a corresponding position (for example, in a box for transportation) by using the hanging member 130 after the first target part 200 and the second target part 300 are loaded. Since the supporting member 120 is substantially located at the central axis of the first target part 200 and the second target part 300, it is not only convenient to load the first target part 200 and the second target part 300 on the loading device 100, but also the center of gravity of the loading device 100 loaded with the first target part 200 and the second target part 300 can be substantially located on the supporting member 120, thereby improving the stability of the loading device 100, so that when the loading device 100 is hung by using the hanging member 130 connected to the supporting member 120, it is convenient to hang. Therefore, in the loading device 100 provided in the embodiment of the present application, the first target part 200 and the second target part 300 are easily transported through the mutual cooperation of the base 110, the support member 120 and the lifting member 130.

[0079] It should be noted that, since the first target part 200 and the second target part 300 are relatively large and heavy, the relevant hoisting method usually adopts a plurality of hoisting points set around the circumference of the relevant device loaded with the first target part 200 and the second target part 300 for hoisting. In order to make the hoisting process smooth to improve safety and reduce damage to the first target part 200 and the second target part 300, it is usually necessary to debug multiple hoisting points, which takes a lot of time and requires a variety of assembly tools and debugging processes to complete the debugging, resulting in the process of disassembling and transporting the first target part 200 and the second target part 300 being cumbersome and difficult to carry out. In the embodiment of the present application, the inventor of the present application adopts a method that is completely different from the common hoisting method for the first target part 200 and the second target part 300 with a large volume and weight in the related art. A hoisting point is set in the direction of the central axis of the loading device 100 loaded with the first target part 200 and the second target part 300, and the first target part 200 and the second target part 300 are loaded using a roughly T-shaped structure formed by the base 110 and the support part 120. This not only facilitates the loading of the first target part 200 and the second target part 300 on the loading device 100, but also can use the gravity of the first target part 200 and the second target part 300 to improve the stability during the hoisting process.

[0080] Figure 4 Shows Figure 1 The illustrated three-dimensional structural diagram of the buffer assembly 140 of the loading device 100; for ease of explanation, only the contents related to the embodiment of the present application are shown.

[0081] In some embodiments, please refer to Figure 1 and Figure 2 , and combined with reference Figure 4 The loading device 100 further includes a plurality of buffer components 140 , and all buffer components 140 are connected to a side of the base 110 away from the support member 120 along the circumference of the base 110 .

[0082] Since the buffer component 140 can provide a certain buffer force, during the transportation of the loading device 100 loaded with the first target part 200 and the second target part 300, the buffer component 140 can be used to improve the stability of the loading device 100, thereby improving the safety during transportation and reducing the risk of damage to the first target part 200 and the second target part 300.

[0083] Figure 5 Shows Figure 1 The three-dimensional structure diagram of the coil spring 141 in the buffer assembly 140 of the loading device 100 is shown; for the convenience of explanation, only the content related to the embodiment of the present application is shown.

[0084] In some embodiments, please refer to Figures 1 to 4 , and combined with reference Figure 5 , the buffer assembly 140 includes a coil spring 141 and a mounting seat 142. The coil spring 141 has a first central axis L1, and the coil spring 141 is spirally extended around the first central axis L1. The coil spring 141 has a first side c1 and a second side c2 that are relatively arranged in a direction perpendicular to the first central axis L1. The first side c1 of the coil spring 141 is connected to the base 110, and the second side c2 of the coil spring 141 is connected to the mounting seat 142. The mounting seat 142 can be used to support the base 110. Furthermore, a related connection structure (such as a flanging structure) that is convenient for connecting with the box body after subsequent packaging can be provided on the mounting seat 142.

[0085] Thus, compared to the case where the coil spring 141 is vertically arranged to provide elastic force along the first direction F1, since the coil spring 141 is substantially horizontally arranged, each spiral coil in the spiral structure formed by the coil spring 141 along the extension direction of the first central axis L1 can participate in the buffering process. Since adjacent spiral coils are connected to each other, when the loading device 100 receives an external force, no matter which direction the external force is, it can be buffered by means of the pulling force between adjacent spiral coils along the extension direction of the first central axis L1, and the loading device 100 can be reduced from being twisted and tilted, thereby further improving the stability of the loading device 100.

[0086] It can be understood that since the coil spring 141 is arranged along the circumference of the base 110, the elastic force formed by the coil spring 141 is substantially located on the same plane perpendicular to the first direction F1, thereby being able to buffer the loading device 100 in the direction perpendicular to the first direction F1, thereby further improving the stability of the loading device 100.

[0087] Figure 6 Shows Figure 1 The schematic diagram of the front structure of the buffer assembly 140 of the loading device 100 is shown; for the convenience of explanation, only the content related to the embodiment of the present application is shown.

[0088] In some embodiments, please continue Figure 1 , Figure 4 and Figure 5 , and combined with reference Figure 6 The buffer assembly 140 further includes a first mounting member 143 disposed on a side of the base 110 away from the support member 120, and a second mounting member 144 disposed on the mounting seat 142. The first mounting member 143 is provided with a plurality of first through holes k1 sequentially disposed along the extending direction of the first central axis L1, and the second mounting member 144 is provided with a plurality of second through holes k2 sequentially disposed along the extending direction of the first central axis L1. Figure 6In the figure, the approximate positions of the first through hole k1 and the second through hole k2 are indicated by a curved line with arrows. The coil spring 141 has an extension path in which a spiral is extended. Along the extension path, the first side c1 of the coil spring 141 is sequentially provided in all the first through holes k1, and the second side c2 of the coil spring 141 is sequentially provided in all the second through holes k2.

[0089] Thus, by providing the first mounting member 143 and the second mounting member 144, it is not only convenient to install the coil spring 141, but also possible to limit the position of the coil spring 141 by means of the first through hole k1 and the second through hole k2. Since the coil spring 141 is inserted through the first through hole k1 and the second through hole k2, the portion of the coil spring 141 that matches the first through hole k1 and the second through hole k2 can rotate more flexibly during the process of buffering the external force, which is conducive to the aforementioned force transmission between adjacent spiral coils, thereby making full use of various portions of the coil spring 141 to buffer the external force more stably, further improving the stability of the loading device 100.

[0090] Figure 7 A schematic diagram of the top structure of a loading device 100 in an embodiment of the present application is shown; for ease of explanation, only the contents related to the embodiment of the present application are shown.

[0091] In some embodiments, please refer to Figure 1 , and combined with reference Figure 7 , all buffer components 140 are evenly arranged along the circumference of the base 110 .

[0092] In this way, by evenly arranging the buffer components 140 along the circumference of the base 110 , it is helpful to buffer the external forces in various directions.

[0093] In some embodiments, please refer to Figure 7 , along the circumference of the base 110, the central axes of two adjacent coil springs 141 intersect each other at a reference point e. The orthographic projection of the reference point e on the reference plane is located outside the outer contour of the orthographic projection of the base 110 on the reference plane, and the reference plane is a plane perpendicular to the first direction F1.

[0094] In this way, since the directions of the buffering forces provided by the two adjacent coil springs 141 intersect, when the coil springs 141 buffer the external force, the two adjacent coil springs 141 can also cooperate with each other to participate in the buffering process of the external force, further improving the buffering effect. At the same time, since the direction of the buffering force of the two adjacent coil springs 141 points to the outside of the base 110, when the buffer assembly 140 buffers the external force, the external force acting on the loading device 100 can be reduced, thereby further improving the stability of the loading device 100.

[0095] In some embodiments, please refer to Figure 6 The first mounting member 143 and the second mounting member 144 are arranged opposite to each other along the first direction F1.

[0096] In this way, by arranging the first mounting member 143 and the second mounting member 144 relatively to each other along the first direction F1, the coil spring 141 can be connected roughly between the first mounting member 143 and the second mounting member 144 in the first direction F1, thereby not only being able to better support the loading device 100 in the first direction F1, but also being conducive to making full use of the elastic buffering force that the coil spring 141 can generate along the extension direction of its first center axis L1 for buffering.

[0097] In some embodiments, please refer to Figure 7 The base 110 has two first sides b1 arranged opposite to each other along the second direction F2, two second sides b2 arranged opposite to each other along the third direction F3, and a connecting side b3 connecting the first sides b1 and the second sides b2. Four buffer components 140 are provided, and the two first sides b1 and the two second sides b2 are arranged one-to-one corresponding to the four buffer components 140. The first direction F1, the second direction F2 and the third direction F3 are perpendicular to each other.

[0098] In this way, the four corners of the base 110 substantially form a space for installation, which is conducive to placing the loading device 100 in a related component (such as a box). In addition, the extension direction of the first central axis L1 of the coil spring 141 can be parallel to the extension direction of the corresponding side of the coil spring 141, and the corresponding installation and buffering can be achieved in combination with the structure of the base 110.

[0099] In some embodiments, please refer to Figures 1 to 3 The loading device 100 further includes a first locking assembly 150. The first locking assembly 150 is used to fix one end of the first target member 200 facing the base 110 to the base 110.

[0100] Since the first locking assembly 150 can lock the first target component 200 to the base 110 , the stability of the first target component 200 relative to the base 110 is improved.

[0101] Figure 8 A three-dimensional structural schematic diagram of the first locking assembly 150 of the loading device 100 in an embodiment of the present application is shown; for ease of explanation, only the content related to the embodiment of the present application is shown.

[0102] In some embodiments, please refer to Figure 3 , and combined with reference Figure 8 The first locking assembly 150 includes a first locking member 151 and a fastener 152. The first locking member 151 is disposed on the side of the base 110 facing the support member 120. The fastener 152 is penetrated through the first locking member 151 and the base 110 to relatively fix the first locking member 151 and the base 110. The first locking member 151 is used to abut against the first target member 200 along the radial direction of the first target member 200, and the radial direction of the first target member 200 is perpendicular to the first direction F1.

[0103] Specifically, an adjustment hole t may be provided on the first locking member 151, so as to adapt to different locking requirements. The fastener 152 may be a component that matches a screw and a bolt, and the bolt may be limited on the first locking member 151. Of course, the fastener 152 may also be in other structural forms, which are not specifically limited here.

[0104] In this way, by providing a first locking member 151 for abutting against the first target member 200 along the radial direction of the first target member 200, and a fastener 152 provided to cooperate with the first locking member 151, the first target member 200 can be fixed in cooperation with the support member 120. Exemplarily, when the end of the first target member 200 has a flange, the first locking member 151 can abut against the peripheral side surface of the flange.

[0105] In some embodiments, please refer to Figures 1 to 3 The loading device 100 further includes a second locking assembly 160. The second locking assembly 160 is detachably disposed at one end of the supporting body 121 away from the base 110, and the second locking assembly 160 is configured to abut against the second target member 300 along the first direction F1. That is, the second locking assembly 160 substantially abuts against the end surface of the second target member 300 along the first direction F1.

[0106] In this way, by setting up the second locking assembly 160 and utilizing the cooperation between the second locking assembly 160 and the base 110 in the first direction F1, the first target part 200 and the second target part 300 can be limited in the first direction F1, thereby reducing the risk of the first target part 200 and the second target part 300 being offset in the first direction F1, thereby further improving the stability of loading the first target part 200 and the second target part 300.

[0107] Furthermore, in conjunction with reference Figure 3 , Figure 3 The dotted arrows in the figure indicate the approximate force situation. The force at the connection between the first target part 200 and the second target part 300 easily causes the center of gravity of the second target part 300 to shift outward, thereby affecting the stability of the entire device and the stability of the lifting when subjected to external forces during the lifting process or transportation process. When the second locking assembly 160 is provided, the center of gravity of the second target part 300 can be closer to or located at the central axis of the entire device, which is not only conducive to improving the stability of the entire device, but also can protect the part where the first target part 200 and the second target part 300 are connected to each other.

[0108] In some embodiments, please refer to Figures 1 to 3 The second locking assembly 160 includes a second locking member 161 and a first protective member 162. The second locking member 161 is threadedly connected to an end of the support body 121 away from the base 110. The first protective member 162 is disposed on a side of the second locking member 161 facing the base 110, and the first protective member 162 is used to abut against the second target member 300 along the first direction F1.

[0109] For example, the material of the first protection member 162 may be Teflon. Of course, the material of the first protection member 162 may also be other materials that can protect the second target member 300, and no specific limitation is made here.

[0110] Since metal and other related materials have certain mechanical properties, physical properties and chemical properties, metal and other related materials are usually used to make the first target part 200 and the second target part 300 to meet the needs of more usage scenarios (such as aircraft engines). Correspondingly, the loading device 100 can also be made of metal and other related materials to meet the corresponding loading requirements. Therefore, when the first target part 200, the second target part 300 and the loading device 100 are made of metal and other related materials, by setting the first protective member 162, the risk of the second target part 300 being damaged by the second locking member 161 can be reduced.

[0111] In some embodiments, please refer to Figure 1 and Figure 2The second locking member 161 may be configured to have a structure with multiple edges. Specifically, the second locking member 161 has three straight edges that are sequentially spaced along the circumference of the second locking member 161, and two adjacent edges may be connected by means of an arc edge, so that the second locking member 161 has three straight edges and three arc edges.

[0112] In this way, compared with the way the second locking member 161 is constructed as a disc, by configuring the second locking member 161 as a structure with three straight edges and three arc edges as mentioned above, the weight of the second locking member 161 can be reduced, which in turn helps to reduce the overall weight of the loading device 100, facilitates lifting and transportation, and meets relevant transportation needs.

[0113] In some embodiments, please refer to Figure 2 , a plurality of first protection members 162 may be provided, and all first protection members 162 are arranged around the central axis of the second locking member 161. Specifically, in the case where the second locking member 161 has three sides, a plurality of first protection members 162 may be provided on each side of the second locking member 161 facing the base 110. The first protection member 162 may be connected to the second locking member 161 in a detachable manner such as a bolt connection, so that the first protection member 162 may be used more flexibly to meet the abutment requirements for second target members 300 of different specifications.

[0114] In some embodiments, please refer to Figures 1 to 3 The supporting body 121 includes a first section 121a and a second section 121b connected in sequence along the first direction F1. The first section 121a is used to penetrate the first axial hole, and the second section 121b is used to penetrate the second axial hole. The end of the first section 121a away from the second section 121b is connected to the base 110, and the end of the second section 121b away from the first section 121a can be detachably connected to the hanging member 130. The first supporting portion 122 is located at the end of the first section 121a away from the second section 121b, and the second supporting portion 123 is located at the end of the second section 121b connected to the first section 121a.

[0115] For example, Figure 1 and Figure 2 For example, the first supporting portion 122 can be regarded as a component provided at one end of the supporting body 121 connected to the base 110. In this case, the first supporting portion 122 is provided to protrude relative to the bearing surface m.

[0116] In this way, by correspondingly arranging the first supporting portion 122 and the second supporting portion 123 near the bottom of the first target part 200 and near the bottom of the second target part 300, it is not only further convenient to install the first target part 200 and the second target part 300, but also possible to utilize the gravity of the first target part 200 and the second target part 300 themselves to achieve the first supporting portion 122 and the second supporting portion 123 to cooperate with their respective corresponding target parts.

[0117] Of course, in some other embodiments, the first supporting portion 122 and the second supporting portion 123 may also be located at other positions of the supporting body 121, as long as the support and detachable connection of the first target part 200 and the second target part 300 can be achieved, and no specific limitation is made here.

[0118] In some embodiments, please refer to Figures 1 to 3 The second section 121b may include a first portion P1 and a second portion P2 connected in sequence along the first direction F1, one end of the first portion P1 is connected to the first section 121a, the other end of the first portion P1 is connected to one end of the second portion P2, and the other end of the second portion P2 may be provided with a threaded section, which may be threadedly connected to the hanging member 130. The first portion P1 and the second portion P2 may form a shoulder at the connection, which may limit the first locking member 161.

[0119] It should be noted that the radial dimensions of the first section 121a and the second section 121b can be set according to usage requirements and are not specifically limited herein.

[0120] In some embodiments, please refer to Figures 1 to 3 The loading device 100 further includes a second protective member 170 . The second protective member 170 is disposed on a side of the first supporting portion 122 away from the base 110 .

[0121] For example, the material of the second protection member 170 may be Teflon. Of course, the material of the second protection member 170 may also be other materials that can protect the first target member 200, and no specific limitation is made here.

[0122] With reference to the above, by providing the second protection member 170 , the risk of the first target member 200 being damaged by the first support portion 122 can be reduced.

[0123] In some embodiments, please refer to Figures 1 to 3 The loading device 100 further includes a third protective member 180 , which is disposed on a side of the second supporting portion 123 away from the base 110 .

[0124] For example, the material of the third protection member 180 may be Teflon. Of course, the material of the third protection member 180 may also be other materials that can protect the second target member 300, and no specific limitation is made here.

[0125] With reference to the above, by providing the third protection member 180 , the risk of the second target member 300 being damaged by the second support portion 123 can be reduced.

[0126] It should be noted that, when the second protection member 170 is provided, when the first support portion 122 and the first target member 200 are detachably connected by means of a bolt structure, the bolt structure can also pass through the second protection member 170. When the third protection member 180 is provided, when the second support portion 123 and the second target member 300 are detachably connected by means of a bolt structure, the bolt structure can also pass through the third protection member 180.

[0127] In some embodiments, please refer to Figure 1 and Figure 2 The base 110 is provided with a counterweight hole z. The counterweight hole z is configured to position the center of gravity of the loading device 100 on the central axis of the supporting body 121 when the loading device 100 loads the first target part 200 and the second target part 300. The extension direction of the central axis of the supporting body 121 is parallel to the first direction F1.

[0128] Exemplarily, a plurality of counterweight holes z may be provided, and all counterweight holes z may be arranged around the central axis of the support body 121. The arrangement of the counterweight holes z is not specifically limited, as long as the center of gravity of the loading device 100 in the loaded state is located on the central axis of the support body 121.

[0129] In this way, by setting the counterweight hole z, it is not only beneficial to reduce the weight of the entire device, but also the center of gravity of the entire device can be adjusted, thereby improving the stability of the lifting and facilitating the lifting.

[0130] In some embodiments, please refer to Figure 1 and Figure 2 The loading device 100 further includes a plurality of reinforcement members J. All reinforcement members J are arranged around the circumference of the support body 121, and each reinforcement member J connects the support body 121 and the base 110. Exemplarily, the reinforcement member J can be configured as a rib plate. Of course, the reinforcement member J can also be configured as other structures, which are not specifically limited here.

[0131] In this way, by providing the reinforcement member J, it is beneficial to improve the supporting stability of the supporting body 121 and improve the overall structural strength of the device.

[0132] Based on the same invention concept, please continue to refer to Figure 3The embodiment of the present application provides a loading unit, comprising a first target part 200, a second target part 300 and a loading device 100 in any of the above embodiments. The loading device 100 loads the first target part 200 and the second target part 300 along a first direction F1.

[0133] The advantages possessed by the loading device 100 in any of the above embodiments are also possessed by the loading unit, and no specific limitation is made here.

[0134] In some embodiments, the first target part 200 and the second target part 300 are used in an aircraft engine, the first target part 200 is a fan, and the second target part 300 is a booster module. Of course, in some other embodiments, the first target part 200 and the second target part 300 can be other parts, which are not specifically limited here.

[0135] In summary, the loading device 100 provided in the embodiment of the present application, by providing a base 110 and a support member 120 matched with the base 110, adopts a method of hoisting from the central axis direction of the loading device 100, which is not only convenient for loading the first target part 200 and the second target part 300, but also makes the hoisting method simpler and easier to operate, and also makes the overall structure of the loading device 100 simpler, reduces the cumbersome steps of installation and debugging during the hoisting process, and improves the safety of hoisting and transportation. The first support part 122, the second support part 123, the first locking assembly 150 and the second locking assembly 160 cooperate in various directions to further improve the stability of loading. By setting the buffer assembly 140 and making the coil spring 141 roughly arranged horizontally, the intersection of the central axis of the adjacent coil springs 141 is located outside the overall device, thereby making full use of the elastic buffer force of the coil spring 141 itself and the process of the adjacent coil springs 141 cooperating with each other for buffering, thereby improving the stability of the overall device during transfer and transportation, and reducing the influence of external forces on the first target part 200 and the second target part 300. By setting relevant protective parts, the first target part 200 and the second target part 300 loaded by the loading device 100 can be protected. It can be seen that the loading device 100 provided in the embodiment of the present application can not only adapt to the use requirements in complex environments, but also meet the needs of long-term storage and transportation.

[0136] It should be noted that, when the first target part 200 and the second target part 300 are respectively the fan and the boost module of the aerospace engine, since the fan and the boost module are important life parts of the aerospace engine, they are expensive, and require a completely closed environment during the hoisting and transportation process, and need to be waterproof, sun-proof, dust-proof and shock-absorbing. By using the loading device 100 provided in the embodiment of the present application, not only can the loading device 100 loaded with the fan and the boost module be hoisted into the container, by using the container in combination, the closed environment requirements can be met, and the stability, safety and shock absorption requirements can also be met.

[0137] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0138] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
