Description

Technical Field

[0001] This application relates to the field of boarding bridge technology, and in particular to a passageway and boarding bridge. Background Technology

[0002] Airport boarding bridges typically consist of an inner passageway and an outer passageway that can extend and retract relative to the inner passageway. The rear end of the inner passageway connects to a rotating platform, and the front end extends into the outer passageway. The sliding joints of the inner passageway are located at the corners of the outer passageway, enabling relative movement between the inner and outer passageways. Existing boarding bridges usually employ two fully welded steel structural members located at the corners of the outer passageway to support and limit the sliding joints of the inner passageway. However, fully welding these two steel structural members requires high welding standards, results in long weld seams, and extends the welding time, leading to low production efficiency and high production costs. Utility Model Content

[0003] The main purpose of this application is to provide a passageway and boarding bridge that does not require full welding, reduces weld length, and reduces welding time.

[0004] To achieve the above objectives, this application adopts the following technical solution: According to one aspect of this application, a passage is provided, disposed in a boarding bridge, the passage including an outer passage and an inner passage disposed inside the outer passage, the inner passage being retractable relative to the outer passage, wherein the outer passage includes a first sidewall and a second sidewall, a bottom wall, and at least two connecting members respectively disposed on both sides of the outer passage; the bottom wall connects the first sidewall and the second sidewall, and together with the first sidewall, the second sidewall, and the bottom wall, forms a passage space; at least two connecting members respectively connect the first sidewall, the second sidewall, and the bottom wall, each connecting member including a limiting part and a supporting part, the limiting part being used to limit the position of the inner passage between the first sidewall and the second sidewall, the supporting part being used to support the inner passage, and the projection of the connecting member on a plane perpendicular to the length direction of the passage being "L" shaped.

[0005] According to one embodiment of this application, the connector is an integrally formed connector or a sheet metal connector formed by multiple bending processes.

[0006] According to one embodiment of this application, the connector is a connector with at least a partially hollow structure.

[0007] According to one embodiment of this application, the connector further includes reinforcing ribs disposed in the cavity of the connector.

[0008] According to one embodiment of this application, the reinforcing rib is formed by bending the connector portion.

[0009] According to one embodiment of this application, the connector includes a first square tube and a second square tube, the limiting portion includes the surface of the first square tube facing the inner channel, and the supporting portion includes the surface of the second square tube facing the inner channel.

[0010] According to one embodiment of this application, the support portion and / or the limiting portion are provided with a wear-resistant strip.

[0011] According to one embodiment of this application, the outer channel further includes a top wall, which is connected to the first side wall and the second side wall respectively by two of the aforementioned connectors.

[0012] According to one embodiment of this application, the inner channel has the same shape as the outer channel, and the inner channel also includes at least two or four of the connectors.

[0013] According to another aspect of this application, a boarding bridge is provided, including the above-mentioned passageway.

[0014] As can be seen from the above technical solution, the advantages and positive effects of the channel proposed in this application are as follows: The channel proposed in this application uses a single connector instead of the original structure formed by fully welding two steel structural components. This avoids the processing steps of welding square tubes and angle steel, reducing the length of the channel sidewall welds by 70%, significantly reducing welding time, and improving production efficiency. In the channel proposed in this application, the projection of the connector onto a plane perpendicular to the channel length direction is "L"-shaped, which can limit and support the moving parts of the inner channel.

Detailed Implementation

[0022] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this application will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0023] In the following description of various exemplary embodiments of this application, reference is made to the accompanying drawings, which form part of this application, and which illustrate by way of example different exemplary structures, systems, and steps that can implement various aspects of this application. It should be understood that other specific solutions to components, structures, exemplary devices, systems, and steps may be used, and structural and functional modifications may be made without departing from the scope of this application. Furthermore, while the terms “above,” “between,” “within,” etc., may be used in this specification to describe different exemplary features and elements of this application, these terms are used herein for convenience only, such as the orientation according to the examples described in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of this application.

[0024] It is understood that the terms "comprising" and "having," and any variations thereof, in the embodiments of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to these processes, methods, products, or devices.

[0025] As used herein, “about,” “approximately,” “essentially,” or “substantially” includes the value and the average value within an acceptable range of deviations from a particular value as determined by one of ordinary skill in the art, taking into account the measurement under discussion and a particular number of errors associated with the measurement (i.e., limitations of the measurement system). For example, “about” may mean within one or more standard deviations of the value, or, for example, within ±30%, ±20%, ±15%, ±10%, ±5%. Furthermore, the use of “about,” “approximately,” “essentially,” or “substantially” herein may be chosen to select a more acceptable range of deviations or standard deviations depending on the nature of the measurement, the cutting nature, or other properties, and may not require a single standard deviation to apply to all properties.

[0026] Furthermore, relative terms such as “down” or “bottom” and “up” or “top” may be used herein to describe the relationship between one element and another, as illustrated in the figures. It should be understood that relative terms are intended to include different orientations of the device beyond those shown in the figures. For example, if a device in one figure is flipped, an element described as being “down” to another element will be oriented “up” to that element. Thus, the exemplary term “down” can include both “down” and “up” orientations, depending on the specific orientation of the figure. Similarly, if a device in one figure is flipped, an element described as being “below” or “under” another element will be oriented “above” that element. Thus, the exemplary terms “above” or “below” can include both “up” and “down” orientations.

[0027] This document describes exemplary embodiments with reference to cross-sectional views, which are schematic diagrams of idealized embodiments. Therefore, variations in the shape of the illustrations can be expected as a result of, for example, manufacturing techniques and / or tolerances. Consequently, the embodiments described herein should not be construed as limited to the specific shapes of the regions shown herein, but rather include, for example, shape deviations caused by manufacturing processes. For example, regions shown or described as flat may generally have rough and / or non-linear characteristics. Furthermore, the acute angles shown may be rounded. Therefore, the regions shown in the figures are schematic in nature, and their shapes are not intended to show the precise shapes of the regions, nor are they intended to limit the scope of this application.

[0028] See Figures 1 to 2The passage 1 of this application is installed in a boarding bridge. The passage 1 includes an outer passage 10 and an inner passage 20 disposed inside the outer passage 10. The inner passage 20 is retractable relative to the outer passage 10 and is provided with a sliding pair 205 for the inner passage 20 to move relative to the outer passage 10. The outer passage 10 includes a first side wall 101 and a second side wall 102, a bottom wall 103, and at least two connecting members 30 respectively disposed on both sides of the outer passage 10. The bottom wall 103 connects the first side wall 101 and the second side wall 102, and together with the first side wall 101, the second side wall 102, and the bottom wall 103, forms a passage space. The inner passage 20 is disposed in this passage space and includes a first inner side wall 201, a second inner side wall 202, and an inner bottom wall 203. The first inner sidewall 201 is adjacent to the first sidewall 101 of the outer channel 10, the second inner sidewall 202 is adjacent to the second sidewall 102 of the outer channel 10, and the inner bottom wall 203 is adjacent to the bottom wall 103 of the outer channel 10.

[0029] At least two connectors 30 are respectively connected to the first sidewall 101, the second sidewall 102, and the bottom wall 103. Each connector 30 includes a limiting part 301 and a supporting part 302. The limiting part 301 is used to limit the position of the inner channel 20 between the first sidewall 101 and the second sidewall 102, and the supporting part 302 is used to support the inner channel 20. The projection of the connector 30 on a plane perpendicular to the length direction of the channel 1 is "L" shaped. Movable joints 205 are provided on both sides of the inner channel 20, and the movable joints 205 on both sides are respectively connected to the two connectors 30 and can move along the supporting parts 302 of these two connectors 30. The length direction of the connector 30 is consistent with the length direction of the channel 1 and the length can be substantially the same, or two or more connectors 30 can be spliced ​​together along the length direction of the channel 1.

[0030] In this application, channel 1 uses a connector 30 instead of the original structure formed by fully welding two steel structural components, avoiding the processing steps of welding two steel structural components together. This can effectively reduce the length of the weld seam on the side wall of channel 1 and significantly reduce the welding time. Furthermore, the projection of connector 30 on the plane perpendicular to the length direction of channel 1 is "L" shaped, which can limit and support the moving pair 205 of the inner channel 20.

[0031] A connector 30 is also provided between the first inner sidewall 201 and the inner bottom wall 203 of the inner channel 20, and a connector 30 is also provided between the second inner sidewall 202 and the inner bottom wall 203 of the inner channel 20. The two connectors 30 of the inner channel 20 are respectively connected to the moving pairs 205 on both sides of the inner channel 20.

[0032] In this embodiment, the outer channel 10 further includes a top wall 104, which is connected to the first side wall 101 and the second side wall 102 respectively via two connectors 30. The corresponding inner channel 20 also includes an inner top wall 204, which is connected to the first inner side wall 201 and the second inner side wall 202 respectively via two connectors 30.

[0033] In this embodiment, the connector 30 is a one-piece integral connector with a hollow structure, which can be manufactured using metal processing techniques such as casting or sheet metal fabrication. In other embodiments, the connector 30 may also be a partially hollow structure. The hollow structure reduces weight, and the one-piece molding simplifies the processing steps, avoiding the welding process of the original two steel structural parts, reducing the length of the weld seam on the side wall of channel 1, significantly reducing welding time, and significantly improving production efficiency.

[0034] In this embodiment, the connector 30 disposed between the first sidewall 101 and the bottom wall 103 and the connector 30 disposed between the second sidewall 102 and the bottom wall 103 are arranged opposite to each other. This relative arrangement can also be understood as: the distance between the limiting portions 301 of the two connectors 30 is greater than the distance between the supporting portions 302 of the two connectors 30. The relative arrangement of the two connectors 30 can support the inner channel 20, and the inner channel 20 can be moved relative to the outer channel 10 along the length direction of channel 1 (that is, the length direction of the outer channel 10 and the inner channel 20) via the sliding joint 205. Figure 1 The inner channel 20 can be extended and retracted in a direction perpendicular to the paper, and the connecting member 30 can restrict the moving pair 205 of the inner channel 20 between the opposing surfaces of the two connecting members 30, thus ensuring the positional relationship between the inner channel 20 and the outer channel 10, and ensuring the stability and reliability of the extension and retraction of the inner channel 20 relative to the outer channel 10.

[0035] In this embodiment, the connectors 30 are all located at the four corners of the outer channel 10 and the inner channel 20, see [reference]. Figure 1 The connectors 30 located at the four corners of the inner channel 20 are arranged in pairs facing away from each other. This facing away arrangement can be understood as the distance between the limiting portions 301 of two connectors 30 being less than the distance between the supporting portions 302 of two connectors 30. The two connectors 30 located between the first sidewall 101, the second sidewall 102, and the top wall 104 of the outer channel 10 are also arranged facing away from each other. The orientation of the connectors 30 can be adjusted as needed.

[0036] See Figure 3 In this embodiment, the support portion 302 of the connector 30 is also provided with a wear-resistant belt 305, which is laid along the length direction of the channel 1 and can be a wear-resistant and pressure-resistant steel belt. In some other embodiments, the limiting portion 301 may also be provided with a wear-resistant belt 305.

[0037] like Figure 4 As shown, channel 1 of this application also has a second embodiment, in which channel 1 of the second embodiment is related to... Figures 1 to 3 Compared to channel 1 in the second embodiment, it has a substantially the same structure in its basic construction. Therefore, in the following description of channel 1 in this second embodiment, it will not be described again. Figures 1 to 3 The structure has already been described in the implementation method. Additionally, regarding... Figures 1 to 3 The structures of channel 1 described in the embodiments are labeled with the same reference numerals. Therefore, in the following description of this embodiment, the structures of channel 1 are mainly referred to as channel 1. Figures 1 to 3 The differences between the second embodiment and the channel 1 will be explained. The main difference in the channel 1 of this second embodiment is the structure of the connector 30. In this second embodiment, the connector 30 includes a first square tube 31 and a second square tube 32, the limiting part 301 includes the surface of the first square tube 31 facing the inner channel 20, and the supporting part 302 includes the surface of the second square tube 32 facing the inner channel 20.

[0038] The first square tube 31 is roughly rectangular, and the second square tube 32 is roughly square. One side wall of the second square tube 32 is welded to the side wall of the first square tube 31 located on the long side of the rectangle to form a connector 30. The projection of the connector 30 onto a plane perpendicular to the length of the channel 1 is still "L"-shaped. The first square tube 31 forms the vertical and longer portion of the "L"-shaped structure, while the second square tube 32 forms the horizontal and shorter portion of the "L"-shaped structure. Both the first square tube 31 and the second square tube 32 are hollow structures.

[0039] The connector 30 is welded from the first square tube 31 and the second square tube 32, which avoids the need for full welding of the original two steel structural components, effectively reduces the length of the weld seam on the side wall of the channel 1, and greatly reduces the welding time; and the projection of the connector 30 on the plane perpendicular to the length direction of the channel 1 is "L" shaped, which can realize the limiting and support of the moving pair 205 of the inner channel 20.

[0040] like Figure 5 As shown, channel 1 of this application also has a third embodiment, in which channel 1 of the third embodiment is related to... Figures 1 to 3 Compared to channel 1 in the third embodiment, it has a substantially the same structure in its basic construction. Therefore, in the following description of channel 1 in this third embodiment, it will not be described again. Figures 1 to 3 The structure has already been described in the implementation method. Additionally, regarding... Figures 1 to 3 The structures of channel 1 described in the embodiments are labeled with the same reference numerals. Therefore, in the following description of this embodiment, the structures of channel 1 are mainly referred to as channel 1. Figures 1 to 3The differences between the channel 1 in the third embodiment will be explained. The main difference in the channel 1 of this third embodiment lies in the structure of the connector 30. In this third embodiment, the connector 30 further includes reinforcing ribs 303 disposed in the cavity 304 of the connector 30.

[0041] In this embodiment, one reinforcing rib 303 is provided. In other embodiments, multiple reinforcing ribs may be provided. The reinforcing rib 303 may be continuously provided along the length of the channel 1 or spaced apart along the length of the channel 1. The provision of the reinforcing rib 303 can improve the strength of the connector 30 and enhance its resistance to deformation. The reinforcing rib 303 is provided at the portion of the connector 300 where the cavity 304 and the support portion 302 correspond, which can improve the supporting force of the support portion 302 and prevent the support portion 302 from deforming.

[0042] like Figure 6 As shown, channel 1 of this application also has a fourth embodiment, in which channel 1 of the fourth embodiment is related to... Figures 1 to 3 Compared to channel 1 in the previous embodiment, it has a substantially similar structure in its basic construction. Therefore, in the following description of channel 1 in this fourth embodiment, it will not be described again. Figures 1 to 3 The structure has already been described in the implementation method. Additionally, regarding... Figures 1 to 3 The structures of channel 1 described in the embodiments are labeled with the same reference numerals. Therefore, in the following description of this embodiment, the structures of channel 1 are mainly referred to as channel 1. Figures 1 to 3 The differences between the channel 1 in the fourth embodiment will be explained. The main difference in the channel 1 of this fourth embodiment lies in the structure of the connector 30. In this fourth embodiment, the connector 30 is an integral connector formed by repeatedly bending a sheet metal. After bending, a reinforcing rib 303 is formed in the cavity 304 of the connector 30. The reinforcing rib 303 is formed by partially bending the connector 30.

[0043] In this embodiment, bending forms a reinforcing rib 303. In other embodiments, bending can be repeated to form multiple reinforcing ribs 303. The reinforcing ribs 303 can be continuously arranged along the length of channel 1 or spaced apart along the length of channel 1. The reinforcing ribs 303 can improve the strength of the connector 30 and enhance its resistance to deformation.

[0044] The channel 1 of this application also has a fifth embodiment, which is related to the channel 1 of this fifth embodiment. Figures 1 to 3 Compared to channel 1 in the previous embodiment, it has a substantially similar structure in its basic construction. Therefore, in the following description of channel 1 in this fifth embodiment, it will not be described again. Figures 1 to 3 The structure has already been described in the implementation method. Additionally, regarding... Figures 1 to 3The structures of channel 1 described in the embodiments are labeled with the same reference numerals. Therefore, in the following description of this embodiment, the structures of channel 1 are mainly referred to as channel 1. Figures 1 to 3 The differences between the channel 1 in the implementation method will be explained. In particular, the channel 1 in this fifth implementation method is different mainly in the structure of the connector 30. In this fourth implementation method, the connector 30 is formed by bending a sheet of material multiple times, wherein the sheet of material is bent into a hollow "L" shaped connector 30, and no reinforcing ribs 303 are provided in the cavity 304 of the connector 30.

[0045] In summary, the channel proposed in this application includes an outer channel and an inner channel disposed within the outer channel. The inner channel is capable of telescoping and extending relative to the outer channel. The outer channel includes a first sidewall and a second sidewall, a bottom wall, and at least two connecting members respectively disposed on both sides of the outer channel. The bottom wall connects the first and second sidewalls and, together with the first sidewall, the second sidewall, and the bottom wall, forms a channel space. At least two connecting members connect the first sidewall, the second sidewall, and the bottom wall. One connecting member replaces the original structure formed by fully welding two steel structural members, avoiding the processing steps of welding square tubes and angle steel, reducing the length of the channel sidewall welds, and significantly reducing welding time. The connecting member includes a limiting part and a supporting part. The limiting part is used to restrict the position of the inner channel between the first and second sidewalls, and the supporting part is used to support the inner channel. The projection of the connecting member on a plane perpendicular to the channel length direction is "L"-shaped, which can realize the limiting and support of the moving joint of the inner channel.

[0046] The boarding bridge proposed in this application has the aforementioned passageway, which avoids the processing steps of welding square tubes and angle steel, reduces the length of the weld seam on the side wall of the passageway, significantly reduces welding time, and improves production efficiency.
