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. When it rains, rainwater on the top of the inner passageway is blocked by waterproof strips and diverted to both sides, flowing down the outer walls of the inner passageway and into drainage channels on the floor of the outer passageway. Drainage channels usually have drainage holes at their ends, through which rainwater flows out. End caps cover the drainage holes at the ends of the drainage channels.

[0003] Existing water tank end caps are generally sealed, secured with nails and sealant. During later boarding bridge maintenance, cleaning debris or buildup at the tank end requires complete removal of the end cap. This necessitates removing screws and cutting off sealant, followed by re-nailing and resealing after cleaning – a time-consuming and labor-intensive process. Utility Model Content

[0004] The main purpose of this application is to provide a convenient passage and boarding bridge for cleaning the end of a sink.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] According to one aspect of this application, a passageway is provided, disposed in a boarding bridge, including a water tank and an end cap. The water tank is disposed on the interior floor of the passageway for conveying and draining water. The end cap is disposed at the end of the water tank and covers the water tank, from which water drains. The end cap includes a mounting structure and a flip-top structure. The mounting structure is used to mount the end cap to the water tank; the flip-top structure is mounted to the mounting structure and is switchable between an open position and a closed position.

[0007] According to one embodiment of this application, the flip-top structure includes a fastener for fixing the flip-top structure to the water tank.

[0008] According to one embodiment of this application, a fixing post is provided in the water tank at a position corresponding to the fixing member, and the fixing post is used to fix the fixing member.

[0009] According to one embodiment of this application, the fastener is a screw, and the fastening post is provided with a threaded hole. The screw is fixed in the threaded hole, thereby fixing the flip-top structure to the water tank.

[0010] According to one embodiment of this application, the flip structure includes a plate having opposite sides, one side of which is pivotally connected to the mounting structure and the other side is a free side that can rotate, thereby enabling the flip structure to switch between an open position and a closed position.

[0011] According to one embodiment of this application, the flip-top structure includes a support plate disposed on the surface of the plate facing the water tank for supporting the plate; and / or, the mounting structure is provided with a support frame for supporting the plate.

[0012] According to one embodiment of this application, the mounting structure is U-shaped, and the free side of the plate is located on the opening side of the mounting structure.

[0013] According to one embodiment of this application, the mounting structure includes a water-blocking member disposed on the free side of the flip-top structure to prevent water in the water tank from overflowing onto the surface of the end cap facing away from the water tank.

[0014] According to one embodiment of this application, the water-blocking member includes a first side and a second side connected to each other in an "L" shape, wherein the first side is disposed on the mounting structure along the water flow direction, and the second side is adjacent to the free side of the flip-top structure.

[0015] According to another aspect of this application, a boarding bridge is provided, including the above-mentioned passageway.

[0016] As can be seen from the above technical solution, the advantages and positive effects of the channel proposed in this application are as follows:

[0017] The passage proposed in this application uses an end cap with a flip-top structure set at the end of the water tank. The flip-top structure is installed in the water tank through an installation structure. In this way, when cleaning the garbage or sediment at the end of the water tank, it is not necessary to remove the end cap or cut off the sealant. It is only necessary to open the flip-top structure of the end cap. The operation is simple, which can save the maintenance time and manpower of the boarding bridge, reduce costs, and avoid waste.

[0049] 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, these embodiments are provided so that the present invention 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.

[0050] In the following description of various exemplary embodiments of the present invention, reference is made to the accompanying drawings, which form part of the present invention, and which illustrate by way of example different exemplary structures, systems, and steps that can implement various aspects of the present invention. 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 the present invention. Furthermore, although the terms “above,” “between,” “within,” etc., may be used in this specification to describe different exemplary features and elements of the present invention, these terms are used herein only for convenience, such as the orientation according to the examples shown 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 the present invention.

[0051] It is understood that the terms "comprising" and "having," and any variations thereof, in the embodiments of this utility model 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 such processes, methods, products, or devices.

[0052] Relative terms such as “down” or “bottom” and “up” or “top” may be used herein to describe the relationship of one element to 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 of the figures is flipped, an element described as “down” or “bottom” of another element will be oriented “up” or “top” of that element. Thus, the exemplary term “down” can include both “down” and “up” orientations, and the term “bottom” can include both “bottom” and “top” orientations, depending on the specific orientation of the figure. Similarly, if a device in one of the figures is flipped, an element described as “down” or “bottom” of another element will be oriented “up” or “top” of that element. Thus, the exemplary term “bottom” or “below” can include both “up” and “down” orientations.

[0053] See Figure 1 The passageway described in this application, located on a boarding bridge, includes a water trough 10 and an end cap 20. The water trough 10 is located on the inner floor of the passageway and is used to transport and drain water. When it rains, rainwater at the top of the inner passageway is blocked by a water-retaining strip and diverted to both sides, flowing down the outer wall of the inner passageway and into the water trough 10 on the outer passageway floor. Drainage holes (not shown in the figure) are provided on the bottom surface of the end of the water trough 10, allowing rainwater to drain from the passageway through the drainage holes. The end cap 20 is located at the end of the water trough 10 and covers it. The water trough 10 includes recessed portions and raised portions, spaced apart. The recessed portions serve as flow channels for rainwater, and the water trough 10 includes several recessed portions and several raised portions. The end cap 20 can be fitted to the raised portions to cover the water trough 10. In this case, the end cap 20 simultaneously covers both the recessed portions and the raised portions and contacts the raised portions of the water trough 10. The end cap 20 can also cover the water tank 10 with a gap between it and the protruding portion. In this case, the end cap 20 covers both the recessed portion and the protruding portion, and has a gap with the protruding portion of the water tank 10. The drain hole is provided in the recessed portion of the water tank 10. The recessed portion covered by the end cap 20 of the water tank 10 is connected near the drain hole of the water tank 10. This allows rainwater flowing through multiple recessed portions of the water tank 10 to collect at the drain hole and then be discharged from the drain hole. In some other embodiments, the water tank 10 may also have only one recessed portion. In this case, the end cap 20 is suspended and covers the water tank 10, and rainwater flows from the space between the end cap 20 and the water tank 10 to the drain hole discharge channel.

[0054] The end cap 20 includes a mounting structure 21 and a flip-top structure 22. The mounting structure 21 is used to install the end cap 20 onto the water tank 10; the flip-top structure 22 is installed onto the mounting structure 21 and can be switched between an open and closed position. The open position refers to the state where the flip-top structure 22 is at a certain angle to the water tank 10 (or the floor of the channel), see [reference needed]. Figure 1This allows for the cleaning of trash and sediment at the end of the water tank 10. The closed position refers to the state where the flip-top structure 22 is flush with the water tank 10 (or the floor of the passageway), that is, the position where the flip-top structure 22 covers the end of the water tank 10. At this time, the flip-top structure 22 covers the end of the water tank 10, which can prevent foreign objects from falling into the water tank 10. Furthermore, the flip-top structure 22 is flush with the floor of the passageway, which helps to ensure the comfort and safety of passengers walking through the passageway.

[0055] In this application, the end of the water tank 10 is equipped with an end cover 20 that can be opened and closed. When the flip-top structure 22 of the end cover 20 is opened, garbage or sediment at the end of the water tank 10 can be cleaned. After cleaning, the flip-top structure 22 can be closed directly. There is no need to remove the end cover 20 or cut off the sealant, making operation simple and cleaning convenient. This reduces maintenance time during the boarding bridge maintenance phase, lessens the intensity of maintenance work, and lowers maintenance labor costs.

[0056] See Figures 2 to 5 In this embodiment, the flip-top structure 22 includes a plate 202 with opposite sides. One side is pivotally connected to the mounting structure 21, which can be referred to as the pivot side 2021, and the other side is a free side 2022 that can rotate, thereby enabling the flip-top structure 22 to switch between the open and closed positions. Using a plate 202 to construct the flip-top structure 22 simplifies processing and reduces material usage. The plate 202 can be made of steel, such as stainless steel. The pivot side 2021 of the plate 202, which is pivotally connected to the mounting structure 21, allows the plate 202 to be mounted on the passageway floor. When it is necessary to clean the garbage or sediment at the end of the sink 10, the operator can rotate the plate 202 about the pivot side 2021 via the free side 2022, thereby switching the flip-top structure 22 from the closed position to the open position.

[0057] The shape of the plate 202 can be appropriately adjusted according to the shape of the mounting structure 21. In this embodiment, there is also a folded edge between the pivot side 2021 of the plate 202 and the adjacent side, and the free side 2022 of the plate 202 has a folded angle to adapt to the shape of the mounting structure 21.

[0058] In this embodiment, the flip-top structure 22 includes a support plate 203 disposed on the surface of the plate 202 facing the water tank 10, for supporting the plate 202. Since there is a space between the water tank 10 and the flip-top structure 22, rainwater flows from this space to the drain hole. At the same time, when the flip-top structure 22 is in the closed position, passengers can walk on the plate 202 of the flip-top structure 22. In order to prevent the plate 202 from deforming and ensure the safety of passengers walking, the support plate 203 is provided on the surface of the plate 202 facing the water tank 10.

[0059] In this embodiment, there are two support plates 203, each extending from the pivot side 2021 to the free side 2022, and the two support plates 203 are arranged perpendicular to the extension direction of a single support plate 203. The two support plates 203 are located approximately in the middle of the plate 202, which can better support the plate 202. In some other embodiments, there may be multiple support plates 203. The support plates 203 may be made of steel plate or other materials. The support plates 203 may be welded to the plate 202 or integrally formed with the plate 202.

[0060] In this embodiment, the flip-top structure 22 includes a fixing member 201, which is used to fix the flip-top structure 22 to the water tank 10. When a passenger walks, they may accidentally step on the flip-top panel 202, causing the flip-top structure 22 to switch from the closed position to the open position, which may cause injury to the passenger. By providing the fixing member 201 on the panel 202, the fixing member 201 can fix the panel 202 of the flip-top structure 22 to the water tank 10. In this way, when a passenger steps on the panel 202, the flip-top structure 22 will always be in the closed position, which can ensure the safety of the passenger and prevent the passenger from damaging the flip-top structure 22. When it is necessary to clean the garbage or sediment at the end of the water tank 10, the staff can remove the fixing member 201, so that the panel 202 of the flip-top structure 22 can move relative to the water tank 10. Then, by lifting the free side 2022 of the panel 202, the panel 202 is rotated about the pivot side 2021, thereby switching the flip-top structure 22 from the closed position to the open position.

[0061] In this embodiment, a fixing post (not shown in the figure) is provided at the position of the fixing member 201 in the water tank 10. The fixing post is used to fix the fixing member 201. The fixing post in the water tank 10 cooperates with the fixing member 201 to realize the connection and fixation between the plate 202 of the flip structure 22 and the water tank 10. The fixation is firm and solid. When the passenger steps on the footboard 202, the flip structure 22 will always be in the closed position. When it is necessary to clean the garbage or sediment at the end of the water tank 10, the staff can remove the fixing member 201 from the fixing post, so that the plate 202 of the flip structure 22 and the water tank 10 can move relative to each other. Then, by lifting the free side 2022 of the plate 202, the plate 202 is rotated about the pivot side 2021, thereby switching the flip structure 22 from the closed position to the open position.

[0062] In this embodiment, the fixing member 201 is a screw, and a threaded hole is provided on the fixing post. The screw is fixed in the threaded hole, thereby fixing the flip-top structure 22 to the water tank 10. The cooperation between the screw and the threaded hole enables a detachable connection. The structure is simple, easy to process, low in cost, and effective. Both the fixing member 201 and the fixing post can be made of steel, or other materials can be used, as long as they have sufficient strength.

[0063] See Figure 5 , Figure 5 The structure of the pivot side 2021 of the plate 202 is shown, wherein the pivot side 2021 of the plate 202 is provided with a pivot 204, which is used to connect the mounting structure 21.

[0064] See Figures 6 to 9 In this embodiment, the mounting structure 21 is approximately U-shaped, with the free side 2022 of the plate 202 located on the opening side of the mounting structure 21. See also Figure 6 The mounting structure 21 includes an upper frame 104, a folded frame 105, a bottom frame 103, and a lower frame 102. The upper frame 104, folded frame 105, bottom frame 103, and lower frame 102 are connected sequentially to form a roughly "U"-shaped structure. See [reference needed]. Figure 1 The pivot side 2021 of the plate 202 of the flip structure 22 is pivotally connected to the bottom frame 103 of the mounting structure 21, and the free side 2022 of the flip structure 22 is located in the middle of the "U" shaped structure.

[0065] In this embodiment, the mounting structure 21 further includes a support frame 106, which connects to the upper frame 104 and extends toward the lower frame 102 along the direction from the upper frame 104 to the lower frame 102. There is a distance between the end of the support frame 106 and the lower frame 102, see [reference needed]. Figure 1 A portion of the free side 2022 of the sheet 202 of the flip structure 22 can contact the support frame 106, and another portion is located between the support frame 106 and the lower frame 102. The support frame 106 is used to support the sheet 202.

[0066] In this embodiment, the sides of the plate 202 of the opposing flip structure 22 of the support frame 106, upper frame 104, folded frame 105, bottom frame 103, and lower frame 102 are provided with concave edges, which can accommodate the plate 202 in the mounting structure 21. Fixing ears 210 are also provided on the side of the lower frame 102 and folded frame 105 facing away from the plate 202, for fixing the mounting structure 21 to the ground of the passage. The support frame 106, upper frame 104, folded frame 105, bottom frame 103, and lower frame 102 are made of steel, such as stainless steel; other materials with sufficient strength may also be used.

[0067] In this embodiment, the mounting structure 21 includes a water-blocking component 101, which is disposed on the free side 2022 of the flip-top structure 22 to prevent water in the water tank 10 from overflowing onto the surface of the end cover 20 facing away from the water tank 10. The water-blocking component 101 prevents rainwater from overflowing onto the end cover 20 when the drainage holes are insufficient to drain the rainwater flowing into the water tank 10 in time. The water-blocking component 101, disposed on the free side 2022 of the flip-top structure 22, effectively blocks rainwater overflow. The material of the water-blocking component 101 is steel, such as stainless steel; it can also be other materials with sufficient strength.

[0068] In this embodiment, the water-blocking member 101 includes a first side 1011 and a second side 1012 connected in an "L" shape. The first side 1011 is disposed on the mounting structure 21 along the water flow direction, and the second side 1012 is adjacent to the free side 2022 of the flip-top structure 22. The "L"-shaped water-blocking member 101 can block water more comprehensively. The first side 1011 can prevent rainwater from overflowing onto the channel floor and further overflowing onto the surface of the end cover 20 facing away from the water trough 10. The second side 1012 can also prevent rainwater from overflowing onto the surface of the end cover 20 facing away from the water trough 10.

[0069] In this embodiment, the height of the first side 1011 of the water-blocking member 101 (the dimension of the water-blocking member 101 perpendicular to the channel ground is called the height) is greater than the height of the second side 1012 of the water-blocking member 101. Since the distance between the first side 1011 and the drainage hole is greater than the distance between the second side 1012 and the drainage hole, when the rain is heavy, water is more likely to accumulate at the position of the first side 1011, and the water level is higher. In order to enhance the water-blocking effect of the water-blocking member 101, the height of the first side 1011 is set to be greater than the height of the second side 1012.

[0070] The first side 1011 and the second side 1012 of the water-blocking component 101 can be integrally formed or separately formed and then welded together. The connection between the water-blocking component 101, the upper frame 104, and the support frame 106 can be fixed by welding, or the water-blocking component 101, the upper frame 104, and the support frame 106 can be integrally formed.

[0071] In this embodiment, see Figure 8 The bottom frame 103 of the mounting structure 21 is provided with a shaft hole 107 for mounting a pivot 204, so that the plate 202 of the flip structure 22 can rotate.

[0072] The channel in this application also has a second implementation, the channel of which is related to... Figures 1 to 9 The channel of this second embodiment has a substantially the same structure in its basic construction as that of the first embodiment.

The main difference in the channel of this second embodiment is the installation direction of the support plates 203. In this second embodiment, multiple support plates 203 are arranged along the direction from the pivot side 2021 to the free side 2022, and each support plate 203 extends in a direction perpendicular to the arrangement direction of the multiple support plates 203.

The main difference in the channel of this third embodiment lies in the arrangement of the support plates 203. In this third embodiment, the support plates 203 can be arranged in a crisscrossing or oblique manner.

[0074] The channel in this application also has a fourth embodiment, the channel of which is related to... Figures 1 to 9 Compared to the channel in the previous embodiment, it has a substantially similar structure in its basic construction. Therefore, in the following description of the channel in this fourth embodiment, it will not be described again. Figures 1 to 9 The structure has already been described in the implementation method.

In this fourth embodiment, the support plate 203 can adopt a folded plate structure and is disposed on the surface of the plate 202 facing the water tank 10 to support the plate 202.

[0075] The channel in this application also has a fifth embodiment, the channel of which is related to... Figures 1 to 9 Compared to the channel of the previous embodiment, it has a substantially similar structure in its basic construction.

In this fifth embodiment, the height of the first side 1011 of the water-blocking member 101 is equal to the height of the second side 1012.

[0076] The channel in this application also has a sixth embodiment, the channel of which is related to... Figures 1 to 9 Compared to the channel in the previous embodiment, it has a substantially similar structure in its basic construction. Therefore, in the following description of the channel in this sixth embodiment, it will not be described again. Figures 1 to 9 The structure has already been described in the implementation method. Additionally, regarding... Figures 1 to 9 The structures with the same channel structure described in the embodiments are labeled with the same reference numerals. Therefore, in the following description of this embodiment, the structures with the same channel structure are mainly referred to. ​ The differences in the channels of the embodiments will be explained. In particular, the channels of this sixth embodiment differ mainly in the positions of the pivot 204 and the shaft hole 107. In this sixth embodiment, the pivot 204 is disposed in the mounting structure 21, and the shaft hole 107 is disposed in the plate 202 of the flip cover structure 22.

[0077] The above is a detailed description of several exemplary embodiments of the channel proposed in this application. The following will describe in detail the usage process of the channel proposed in this application.

[0078] Combined with appendix ​ The process of using the channel proposed in this application is as follows:

[0079] When it rains, rainwater at the top of the inner channel is blocked by the water-retaining rubber strip and diverted to both sides, then flows down the outer wall of the inner channel and into the water trough 10 on the ground of the outer channel. Rainwater flows out through the drainage holes at the ends of the water trough 10. The end cover 20 covers the water trough 10, and the flip-top structure 22 of the end cover 20 is in the closed position.

[0080] When it is necessary to clean the garbage or sediment at the end of the sink 10, the operator only needs to loosen the fixing part 201 (screw) of the flip cover structure 22, so that the plate 202 of the flip cover structure 22 is freed from the restraint of the fixing post of the sink 10. Then, the plate 202 is rotated from the free side 2022 around the pivot side 2021 to realize the flip cover structure 22 switching from the closed position to the open position.

[0081] After cleaning, the staff will rotate the board 202 from the free side 2022 around the pivot side 2021. At this time, the flip structure 22 will switch from the open position to the closed position. Then, the flip structure 22 can be fixed with the fastener 201.

[0082] As can be seen from the above usage process of the channel, the channel of this application adopts an end cover 20 with a flip-top structure 22 set at the end of the water tank 10. The flip-top structure 22 is installed on the water tank 10 through the mounting structure 21. In this way, when cleaning the garbage or sediment at the end of the water tank 10, it is not necessary to remove the end cover 20 or cut off the sealant. It is only necessary to open the flip-top structure 22 of the end cover 20. The operation is simple and can save the maintenance time and manpower of the boarding bridge.

[0083] In summary, the channel proposed in this application includes a water tank and an end cap.
