[0052] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0053] like Figures 1 to 10As shown, according to an embodiment of the present disclosure, a cabin section hoist 100 is proposed, comprising: a load-bearing beam 110; at least two clamping assemblies 120, movably arranged on the load-bearing beam 110, the clamping assemblies 120 are used to connect to an end frame 120' of a cabin section 100' to be hoisted, and at least two clamping assemblies 120 are arranged along the extension direction of the load-bearing beam 110; a connecting assembly 130, arranged on the load-bearing beam 110, the connecting assembly 130 is used to connect to a hook of a hoisting device; wherein, along the extension direction of the load-bearing beam 110, the distance between two adjacent clamping assemblies 120 is adjustable.

[0054] The cabin section hoist 100 provided in the embodiment of the present disclosure includes a load-bearing beam 110, a clamping assembly 120 and a connecting assembly 130, wherein the clamping assembly 120 and the connecting assembly 130 are both arranged on the load-bearing beam 110, the number of the clamping assemblies 120 is at least two and the plurality of clamping assemblies 120 are arranged along the extension direction of the load-bearing beam 110, the clamping assembly 120 can be movable relative to the load-bearing beam 110 so that the distance between two adjacent clamping assemblies 120 can be adjusted, the plurality of clamping assemblies 120 can be used to be connected to different positions of the end frame 120' of the cabin section 100' to be hoisted, the connecting assembly 130 can be used to be connected to the hook of the hoisting device, based on the above-mentioned arrangement The cabin section hoist 100 provided in the embodiment of the present disclosure can be connected between the lifting device and the cabin section 100' to be lifted in actual applications, and a plurality of clamping assemblies 120 can be used to clamp and fix the cabin section 100' to be lifted, so that the cabin section 100' to be lifted can be moved stably and safely during the lifting process, and the position of the clamping assembly 120 on the load-bearing beam 110 can be flexibly adjusted, so as to facilitate the clamping and fixation of cabin sections 100' to be lifted of different sizes and specifications, thereby improving the adaptability of the cabin section hoist 100 to the size of the cabin section 100 to be lifted, avoiding frequent replacement of the hoist during the cabin section lifting operation, and being beneficial to improving the efficiency of the cabin section lifting operation and aircraft production.

[0055] It is understandable that the cabin of an aircraft is usually composed of multiple cabin sections; Figure 3 and Figure 4As shown, the cabin section 100' to be lifted generally includes a cylindrical cabin section body 110', and end frames 120' are arranged at both ends of the cabin section body 110'. In actual application, the clamping assembly 120 of the cabin section hoist 100 provided in the embodiment of the present disclosure can penetrate into the end frame 120' through the inner hollow area of ​​the end frame 120', and be clamped on both sides of the end frame 120' in the thickness direction to clamp and fix the cabin section 100' to be lifted. At least one pair of the clamping assemblies 120 among the multiple clamping assemblies 120 can be respectively connected to two relative positions in the radial direction of the aforementioned end frame 120' to improve the force balance of the cabin section 100' to be lifted, and by clamping the end frame 120', the axial direction of the cabin section 100' to be lifted can be made roughly parallel to the gravity direction during the lifting process, thereby realizing vertical lifting of the cabin section 100' to be lifted, which is beneficial to improving the stability and safety of the cabin section 100' to be lifted during the movement.

[0056] It is understandable that the diameters of the two ends of the cabin section 100' to be hoisted may be different. Since the distances between the multiple clamping assemblies 120 of the cabin section hoist 100 provided in the embodiment of the present disclosure can be adjusted, Figure 3 As shown, the distance between a pair of clamping assemblies 120 in the plurality of clamping assemblies 120 can be adjusted according to the size of the end frame 120' at the small diameter end of the cabin section 100' to be hoisted, so that the aforementioned pair of clamping assemblies 120 can clamp the end frame 120' at the small diameter end of the cabin section 100' to be hoisted; or Figure 4 As shown, the distance between a pair of clamping assemblies 120 among the multiple clamping assemblies 120 can be adjusted according to the size of the end frame 120' at the large diameter end of the cabin section 100' to be lifted, so as to facilitate the aforementioned pair of clamping assemblies 120 to clamp the end frame 120' at the large diameter end of the cabin section 100' to be lifted; it is also not difficult to understand that the cabin section hoist 100 provided in the embodiment of the present disclosure can select a specific end frame 120' for clamping according to actual needs, and can have good adaptability to the size of the cabin section 100' to be lifted, while having high flexibility and convenience in use.

[0057] It can be understood that the number of connecting components 130 is at least one; when the number of connecting components 130 is one, the connecting component 130 can be arranged in the middle area of ​​the load-bearing beam 110 along the extension direction of the load-bearing beam 110, and the multiple clamping components 120 can be arranged in a roughly symmetrical form with respect to the median plane in the extension direction of the load-bearing beam 110, so as to help the load-bearing beam 110 maintain a high level during the lifting process, and provide a guarantee for the smooth and safe execution of the cabin section lifting operation; when the number of connecting components 130 is multiple, the multiple connecting components 130 can be arranged in a roughly symmetrical form with respect to the median plane in the extension direction of the load-bearing beam 110, and the multiple clamping components 120 can be arranged in a roughly symmetrical form with respect to the median plane in the extension direction of the load-bearing beam 110, so as to help the load-bearing beam 110 maintain a high level during the lifting process, and provide a guarantee for the smooth and safe execution of the cabin section lifting operation.

[0058] It can be understood that the direction of the aforementioned load-bearing beam 110 is also the axial direction of the load-bearing beam 110 .

[0059] It can be understood that the aforementioned lifting device can be but is not limited to a crane, a hoist, etc.

[0060] like Figure 1 , Figure 2 , Figures 5 to 8 As shown, in some examples, the clamping assembly 120 includes: a sleeve 121, which is movably mounted on the load-bearing beam 110; a mounting plate 122, which is arranged on the sleeve 121, and the mounting plate 122 has a first threaded hole 1201; a first tightening bolt 123, which is threadedly connected to the first threaded hole 1201, and the first tightening bolt 123 is used to abut against one side of the end frame 120'; a limiting plate 124, which is arranged on the sleeve 121, and the limiting plate 124 is arranged opposite to the first tightening bolt 123, and is used to abut against the other side of the end frame 120'.

[0061] In this technical solution, the clamping assembly 120 can be movably sleeved on the load-bearing beam 110 through the sleeve 121, which can improve the matching reliability between the clamping assembly 120 and the load-bearing beam 110 and reduce the risk of the clamping assembly 120 being separated from the load-bearing beam 110; the clamping assembly 120 can use the first tightening bolt 123 and the limit plate 124 to respectively abut against the opposite sides of the end frame 120' of the receiving hoisting cabin section 100', thereby temporarily clamping the end frame 120', and by rotating the first tightening bolt 123, the first tightening bolt can be adjusted. The spacing between the bolt 123 and the limit plate 124 makes it easier for the clamping assembly 120 to clamp end frames 120' of different thicknesses, further improving the adaptability of the cabin section hoist 100 to the cabin section size specifications; when the first tightening bolt 123 and the limit plate 124 respectively abut against the opposite sides of the end frame 120' of the cabin section 100' to be hoisted, the clamping force applied by the clamping assembly 120 to the end frame 120' can also be adjusted by rotating the first tightening bolt 123, which is beneficial to further improve the clamping stability of the cabin section 100' to be hoisted.

[0062] It should be noted that Figures 5 to 7 The first tightening bolt 123 is hidden in the figure to facilitate showing the structure of the rest of the clamping assembly 120.

[0063] For example, Figure 1 and Figure 2 As shown, the number of mounting plates 122 and first tightening bolts 123 of each clamping assembly 120 can be at least two, the number of mounting plates 122 and first tightening bolts 123 are the same and correspond one to one, and multiple first tightening bolts 123 are arranged at intervals. The aforementioned limit plates 124 can be arranged between two adjacent first tightening bolts 123 along the spacing direction of the first tightening bolts 123, so that in actual applications, the distribution range of the clamping force applied by the clamping assembly 120 to the end frame 120' can be expanded, which is beneficial to further improve the clamping stability and reliability of the clamping assembly 120 on the cabin section 100' to be hoisted, and enhance the safety of the cabin section hoist 100.

[0064] For example, Figure 2 and Figure 8As shown, the first tightening bolt 123 may include a bolt head, a bolt rod and an operating rod passed through the bolt rod, the extension direction of the operating rod is different from the extension direction of the bolt rod, the bolt rod is formed with an external thread matched with the first threaded hole 1201 and passed through the first threaded hole 1201, the bolt head and the operating rod are respectively located on both sides of the mounting plate 122, and the bolt head is used to abut against one side of the aforementioned end frame 120', and the end of the bolt head used to abut against the end frame 120' may be provided with an anti-slip layer or a wear-resistant layer, thereby helping to reduce the wear on the end frame 120' and improve the clamping stability and reliability of the cabin section 100' to be hoisted, and based on the aforementioned arrangement, it is also convenient for the operator to use the operating rod to rotate the first tightening bolt 123, which is beneficial to improving the ease of use of the cabin section hoist 100.

[0065] like Figure 7 As shown, in some examples, the limiting plate 124 includes: a plate body 1241, forming a limiting wall; a buffer layer 1242, arranged on the limiting wall, the buffer layer 1242 is used to abut against the other side of the end frame 120'; wherein the buffer layer 1242 is made of elastic material.

[0066] In this technical solution, the limit plate 124 may include a version and a buffer layer 1242. Based on the above settings, the limit plate 124 may use the buffer layer 1242 to abut against the end frame 120' of the cabin section 100' to be hoisted, which is beneficial to reduce damage to the end frame 120' during the clamping process.

[0067] Exemplarily, the aforementioned buffer layer 1242 may be supported by a rubber material.

[0068] For example, Figure 7 As shown, the plate body 1241 can be an L-shaped plate, and the two intersecting plate surfaces on the inner side of the L-shaped plate can both be the aforementioned limiting walls. Correspondingly, the aforementioned buffer layer 1242 can be provided on the two limiting walls, and based on the aforementioned arrangement, in actual applications, one of the two limiting walls can cooperate with the first tightening bolt 123 to respectively abut against the opposite sides of the end frame 120', and the other can be arranged corresponding to the inner wall of the end frame 120' and abut against the inner wall of the end frame 120', thereby further increasing the contact area between the clamping assembly 120 and the end frame 120', and enhancing the limiting effect of the clamping assembly 120 on the end frame 120', which is beneficial to further improve the stability and reliability of the compartment section 100' to be lifted during the lifting process.

[0069] like Figure 1 , Figure 2 and Fig.10As shown, in some examples, the clamping assembly 120 further includes: a second tightening bolt 125 , a second threaded hole 1202 is formed in the wall of the sleeve 121 , the second tightening bolt 125 is threadedly connected to the second threaded hole 1202 and is used to abut against the load-bearing beam 110 .

[0070] In this technical solution, the clamping assembly 120 can utilize the second tightening bolt 125 to abut against the circumferential side of the load-bearing beam 110. It can be understood that by rotating the second tightening bolt 125, the second tightening bolt 125 can be moved closer to or away from the load-bearing beam 110; when the second tightening bolt 125 abuts against the circumferential side of the load-bearing beam, the resistance of the sleeve 121 to the movement of the load-bearing beam 110 increases, which is beneficial to constrain the position of the sleeve 121 on the load-bearing beam 110, and thus can prevent the clamping assembly 120 from moving during the lifting process, which is beneficial to improving the stability and safety of the lifting operation; when the second tightening bolt 125 is separated from the load-bearing beam 110, the resistance of the sleeve 121 to the movement of the load-bearing beam 110 is reduced, thereby facilitating the position adjustment of the clamping assembly 120.

[0071] Exemplarily, the number of the second tightening bolts 125 may be at least two, and the plurality of second tightening bolts 125 are arranged at intervals along the axial direction of the sleeve 121 .

[0072] In some examples, the cross-section of the load-bearing beam 110 is polygonal, the inner wall of the sleeve 121 forms a beam-through channel 1203 , the load-bearing beam 110 is movably disposed in the beam-through channel 1203 , and the cross-sectional shape of the beam-through channel 1203 is adapted to the cross-sectional shape of the load-bearing beam 110 .

[0073] In this technical solution, the sleeve 121 can be movably matched with the load-bearing beam 110 through the beam-penetrating channel 1203, and by setting the cross-sectional shape of the load-bearing beam 110 and the beam-penetrating channel 1203 to be polygonal, the sleeve 121 can be prevented from rotating relative to the load-bearing beam 110, which is beneficial to further improve the stability and safety of the cabin section 100' to be lifted during the lifting process.

[0074] Exemplarily, the load-bearing beam 110 may be a square tube structure or a rectangular tube structure, and correspondingly, the beam-through channel 1203 may be a square or a rectangle, and there is a small gap between the load-bearing beam 110 and the beam-through channel 1203, so that on the one hand, the sleeve 121 can be prevented from rotating relative to the load-bearing beam 110, which is conducive to further improving the stability and safety of the cabin section 100' to be hoisted during the hoisting process; on the other hand, it can also reduce the weight of the load-bearing beam 110, making it easier for operators to manually take the cabin section hoist 100, and can reduce the load capacity requirements of the hoisting device. It can be understood that the aforementioned small gap fit refers to a gap with a width less than or equal to 1 mm formed between the load-bearing beam 110 and the inner circumferential wall of the sleeve 121. Exemplarily, the width of the aforementioned gap can be but is not limited to 0.8 mm, 0.5 mm, 0.2 mm, etc.

[0075] like Fig.10 As shown, in some examples, the load-bearing beam 110 includes: a beam body 111; a protective layer 112, which is arranged on the peripheral side of the beam body 111, and at least part of the protective layer 112 is located between the beam body 111 and the clamping assembly 120, and the protective layer 112 is movably matched with the clamping assembly 120.

[0076] In this technical solution, the load-bearing beam 110 can be flexibly matched with the clamping assembly 120 through the protective layer 112, thereby reducing the damage of the beam body 111 during use, extending the service life of the beam body 111, and helping to reduce the wear of the clamping assembly 120, thereby reducing the component maintenance and replacement costs of the cabin section hoist 100.

[0077] For example, Fig.10 As shown, when the cross section of the load-bearing beam 110 is polygonal, the load-bearing beam 110 can be made of a rectangular steel tube or a square steel tube, and accordingly, the four side walls of the load-bearing beam 110 can all be provided with the aforementioned protective layer 112 .

[0078] In some examples, the hardness of the protective layer 112 is less than the hardness of the beam body 111 ; and / or the friction coefficient between the protective layer 112 and the clamping assembly 120 is less than the friction coefficient between the beam body 111 and the clamping assembly 120 .

[0079] In this technical solution, the hardness of the protective layer 112 can be set to be smaller than the hardness of the beam body 111. Therefore, during use, if the cabin section 100' to be lifted comes into contact with the load-bearing beam 110, the load-bearing beam 110 can use the protective layer 112 to buffer the contact force to avoid damaging the beam body 111 and the cabin section 100' to be lifted, which is beneficial to ensuring the production quality of the cabin section 100' to be lifted.

[0080] In this technical solution, the friction coefficient between the protective layer 112 and the clamping assembly 120 can be set to be smaller than the friction coefficient between the beam body 111 and the clamping assembly 120, so that when the clamping assembly 120 moves relative to the load-bearing beam 110, the resistance encountered by the clamping assembly 120 can be reduced, making it easier for the load-bearing assembly to adjust its position more smoothly and conveniently.

[0081] It can be understood that in this technical solution, while setting the hardness of the protective layer 112 to be less than or equal to the hardness of the beam body 111, the friction coefficient between the protective layer 112 and the clamping assembly 120 can be set to be less than the friction coefficient between the beam body 111 and the clamping assembly 120.

[0082] It can be understood that the aforementioned constraints on hardness and friction coefficient can be achieved based on the material selection and / or surface treatment of the protective layer 112, the beam body 111 and the clamping assembly 120. The specific materials and surface treatment methods of the protective layer 112, the beam body 111 and the clamping assembly 120 can be selected based on actual needs, and no excessive restrictions are made here.

[0083] In some examples, the beam body 111 is made of steel; and / or the protective layer 112 is made of polytetrafluoroethylene.

[0084] In this technical solution, the beam body 111 can be made of steel, for example, a rectangular steel pipe or a square steel pipe, so as to ensure the structural strength of the beam body 111 and enhance the load-bearing performance of the cabin section hanger 100.

[0085] In this technical solution, the protective layer 112 can be made of polytetrafluoroethylene, so that there can be a smaller friction coefficient between the clamping assembly 120 and the protective layer 112. When the clamping assembly 120 moves relative to the load-bearing beam 110, the resistance encountered by the clamping assembly 120 can be reduced, which facilitates the load-bearing assembly to adjust its position more smoothly and conveniently. The structural reliability of the protective layer 112 can also be ensured, and the cost of the protective layer 112 can be reduced, which is beneficial for the protective layer 112 to provide reliable structural protection for the beam body 111.

[0086] It can be understood that in this technical solution, while the beam body 111 can be made of steel, the protective layer 112 can be made of polytetrafluoroethylene, so that the hardness of the protective layer 112 can be less than or equal to the hardness of the beam body 111, and the friction coefficient between the protective layer 112 and the clamping assembly 120 can be made smaller than the friction coefficient between the beam body 111 and the clamping assembly 120.

[0087] like Figure 1 and Figure 2As shown, in some examples, the connection assembly 130 includes: a connection plate 131, which is arranged on the load-bearing beam 110, and the connection plate 131 has a mounting hole; a shackle 132, which is passed through the mounting hole; and a sling 133, which is connected to the shackle 132, and the sling 133 is used to be connected to the hook.

[0088] In this technical solution, the connecting assembly 130 can utilize the sling 133 to dock with the lifting device, and the density of the sling 133 is relatively low, which is beneficial to reducing the overall mass of the cabin section hoist 100, facilitating the operator to manually take the cabin section hoist 100, and can reduce the load capacity requirements for the lifting device; at the same time, the sling 133 is connected to the connecting plate 131 through the shackle 132, which can ensure the connection reliability between the sling 133 and the load-bearing beam 110 while facilitating the replacement of the sling 133, thereby improving the ease of use of the cabin section hoist 100.

[0089] It is understandable that in practical applications, the shackle 132 and the sling 133 can be finished products, and the model specifications of the shackle 132 and the sling 133 can be selected in combination with the mass of the largest compartment to be hoisted. For example, the sling 133 can be an annular sling 133, and the length of the sling 133 can be greater than or equal to 500 mm and less than or equal to 1000 mm.

[0090] It can be understood that the shackle 132 is detachably connected between the connecting plate 131 and the sling 133 .

[0091] like Figure 1 and Figure 2 As shown, in some examples, the connecting plate 131 is arranged corresponding to the middle area in the extension direction of the load-bearing beam 110 .

[0092] In this technical solution, the connecting plate 131 is arranged corresponding to the middle area in the extension direction of the load-bearing beam 110, which is conducive to the smooth lifting of the load-bearing beam 110 during the lifting process, and provides a guarantee for the smooth and safe execution of the cabin section lifting operation.

[0093] In some feasible examples, the load-bearing beam 110 and the connecting plate 131 may be an integrated structure, thereby improving the connection reliability between the connecting assembly 130 and the load-bearing beam 110 and providing a more reliable guarantee for the smooth and safe execution of the cabin section lifting operation.
