[0038] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, terms such as "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components.

[0039] See Figures 1 to 12 As shown, this embodiment provides a receiving port. The receiving port has an installation area 20. The receiving port includes a safety boot 10. The installation area 20 is provided with limiting holes, and the safety boot 10 is provided with limiting posts; and / or, the installation area 20 is provided with limiting posts, and the safety boot 10 is provided with limiting holes; the limiting posts can be limited in the limiting holes so that the safety boot 10 can be installed in the installation area 20. Based on this structure, through the cooperation of the limiting holes and the limiting posts, the safety boot 10 can be installed in the installation area 20 of the receiving port, thereby reducing the possibility of the position of the safety boot 10 shifting, and further reducing the risk of damage to the aircraft cabin door.

[0040] To clearly describe the technical solution of the present application, the limiting hole provided in the safety boot 10 is named the first limiting hole 11, and the limiting post provided in the installation area 20 is named the first limiting post 21; the limiting post provided in the safety boot 10 is named the second limiting post 12, and the limiting hole provided in the installation area 20 is named the second limiting hole 22.

[0041] In some embodiments, see Figures 1 to 3 As shown, the installation area 20 is provided with a first limiting post 21, and the safety boot 10 is provided with a first limiting hole 11. The first limiting post 21 can be limited in the first limiting hole 11.

[0042] In some embodiments, see Figures 7 to 10 As shown, the installation area 20 is provided with a second limiting hole 22, and the safety boot 10 is provided with a second limiting post 12. The second limiting post 12 can be limited in the second limiting hole 22.

[0043] In some embodiments, the installation area 20 is provided with a first limiting post 21 and a second limiting hole 22, and the safety boot 10 is provided with a first limiting hole 11 and a second limiting post 12. The first limiting post 21 can be limited in the first limiting hole 11, and the second limiting post 12 can be limited in the second limiting hole 22.

[0044] Exemplarily, the safety boots 10 in this embodiment can be mobile safety boots. The working position of the mobile safety boots can be selected according to different styles of aircraft doors. In the aircraft receiving state, the mobile safety boots are placed in the area between the floor of the aircraft receiving port and the bottom of the aircraft door to prevent the opened aircraft door from scraping against the floor of the aircraft receiving port, so as to protect the aircraft door. Specifically, when the boarding bridge is docked to the aircraft and the aircraft door is opened, the staff will place the safety boots 10 under the opened aircraft door, for example, at the directly below position; before the aircraft door is closed, the staff will take away the safety boots 10 from under the aircraft door. Usually, the safety boots 10 are placed in a storage box for storage.

[0045] It should be understood that the structure and working principle of the mobile safety boots should be understandable to those skilled in the art, and are well-known and easy to implement for those skilled in the art. Therefore, this embodiment will not be described in detail.

[0046] In one embodiment, the aircraft receiving port further includes a floor, and the installation area 20 is formed on the floor.

[0047] Exemplarily, the floor includes a fixed floor (not shown in the figure) and a movable floor 30. The movable floor 30 is telescopically connected to the fixed floor to dock the aircraft.

[0048] In this embodiment, the installation area 20 is formed on the movable floor 30. That is to say, the limit holes and the limit posts can be directly provided on the movable floor 30. Specifically, as shown in Figure 2 shown, the first limit post 21 can be directly provided on the movable floor 30; as shown in Figure 8 shown, the second limit hole 22 can be directly provided on the movable floor 30; of course, the first limit post 21 and the second limit hole 22 can be provided on the movable floor 30 at the same time.

[0049] In some embodiments, as shown in Figure 1 and Figure 2 shown, the number of the first limit posts 21 is multiple. The multiple first limit posts 21 are arranged at intervals along the extending direction of the installation area 20. The first limit hole 11 can cooperate with the first limit posts 21 at different positions, so that the safety boots 10 can be placed at different positions. That is to say, along the extending direction of the installation area 20, there are multiple positions available for placing the safety boots 10. Among them, in the state of docking the aircraft, the extending direction of the installation area 20 faces the aircraft door.

[0050] The number of the first limiting holes 11 can be one or multiple. When the number of the first limiting holes 11 is multiple, the distance between two adjacent first limiting holes 11 is the same as the distance between two adjacent first limiting posts 21, ensuring that all the first limiting posts 21 can be limited in the corresponding first limiting holes 11.

[0051] In some other embodiments, it can also be that the number of the first limiting posts 21 is one and the number of the first limiting holes 11 is multiple. The multiple first limiting holes 11 are arranged at intervals along the length direction of the safety boot 10, and the first limiting post 21 can be limited in the first limiting holes 11 at different positions to change the placement position of the safety boot 10. Of course, the number of the first limiting posts 21 can also be multiple, and the first limiting posts at different positions are limited in the corresponding first limiting holes.

[0052] In other embodiments, it can also be that multiple second limiting holes 22 are arranged at intervals along the extending direction of the installation area 20, and the second limiting posts 12 can be limited in the second limiting holes 22 at different positions, so as to place the safety boot 10 at different positions. The number of the second limiting posts 12 can be one or multiple.

[0053] It should be understood that the extending direction of the installation area 20 (indicated by the arrow direction D in Figure 1 ) can be consistent with the telescopic direction of the movable floor 30 relative to the fixed floor.

[0054] In other embodiments, the installation area 20 can also be formed on the fixed floor. Of course, the installation area 20 can also be formed on the surface of other structures at the receiving port that can be used to place the safety boot 10.

[0055] In one embodiment, the receiving port further includes a limiting seat 40. The limiting seat 40 is installed on the floor, and the installation area 20 is formed on the limiting seat 40.

[0056] Exemplarily, the limiting seat 40 can be installed on the movable floor 30, and the installation area 20 is formed on the surface of the limiting seat 40 away from the movable floor 30. For example, the limiting seat 40 can be detachably installed on the movable floor 30 through fasteners, and the fasteners can include bolts, nuts, etc.

[0057] Exemplarily, referring to Figure 4 and Figure 5 as shown, the limiting seat 40 is in a rectangular plate-like structure. The limiting seat 40 has two opposite long side edges 41 and two opposite short side edges 42, and the length of the long side edge 41 is greater than the length of the short side edge 42.

[0058] The installation area 20 has an extending direction (in Figure 6The direction D of the arrow in ( ), the extending direction of the installation area 20 is the same as the extending direction of the long side 41 of the limiting seat 40. See Figure 5 As shown, a plurality of first limiting posts 21 are arranged at intervals along the extending direction of the long side 41 of the limiting seat 40. The first limiting holes 11 provided on the base of the safety boot 10 can cooperate with the first limiting posts 21 at different positions, so that the safety boot 10 can be placed at different positions. That is to say, along the extending direction of the installation area 20, there are multiple positions for the safety boot 10 to be placed.

[0059] In one embodiment, the limiting seat 40 can move relative to the installation area 20 to change the positions of the limiting holes or limiting posts on the limiting seat 40.

[0060] Taking the limiting seat 40 provided with the first limiting posts 21 as an example, see Figure 6 As shown, the area within the dash-dotted rectangular frame represents the installation area 20, the solid rectangular frame represents the limiting seat 40 in the first position, and the dashed rectangular frame represents the limiting seat 40 in the second position. The limiting seat 40 can move from the first position to the second position, thereby changing the position of the first limiting posts 21 on the limiting seat 40.

[0061] Similarly, when the limiting seat 40 is provided with the second limiting holes 22, the position of the second limiting holes 22 on the limiting seat 40 can also be changed by moving the limiting seat 40.

[0062] In other embodiments, the position of the limiting seat 40 can be fixed relative to the installation area. The limiting seat 40 is provided with a plurality of installation positions, and the first limiting posts 21 can be installed in different installation positions to change the position of the first limiting posts 21.

[0063] Exemplarily, the installation position can be a through hole or a blind hole. When the safety boot is provided with the second limiting posts 12, the redundant installation positions can be used as the second limiting holes to cooperate with the second limiting posts 12.

[0064] In other embodiments, a plate portion can also be provided on the limiting seat 40. The second limiting holes 22 are provided on the plate portion. The plate portion can move relative to the limiting seat 40 and can be fixedly installed at different positions of the limiting seat, so as to realize the change of the position of the second limiting holes. Of course, the first limiting posts 21 can also be provided on the plate portion.

[0065] In one embodiment, the limiting posts or limiting holes can be directly provided on the bottom plate 101 of the safety boot 10. In other embodiments, see Figure 10 As shown, an installation seat 50 can also be provided on the bottom plate 101 of the safety boot 10, and the limiting posts or limiting holes are provided on the installation seat 50.

[0066] In one embodiment, see Figure 11 andFigure 12 As shown, when the safety boots 10 are provided with the second limit post 12, the second limit post 12 includes a hollow post 121, a limit portion 122 and a linkage rod 123. The hollow post 121 has a cavity, and the cavity penetrates at least one end of the hollow post 121 located above the installation area 20. An installation hole 12111 is provided on the side wall of the hollow post 121 located below the installation area 20, and the installation hole 12111 communicates with the cavity. The limit portion 122 is movably installed in the installation hole 12111. The linkage rod 123 is inserted through the cavity, and an avoidance groove 12311 is provided on the circumferential side wall of the linkage rod 123. The linkage rod 123 has a first working position and a second working position. In the first working position, the avoidance groove 12311 is misaligned with the installation hole 12111, so that the limit portion 122 protrudes from the outer side wall of the hollow post 121 to limit the separation of the limit post from the limit hole. In the second working position, the avoidance groove 12311 communicates with the installation hole 12111, so that the limit portion 122 can move into the avoidance groove 12311 and the limit post can be removed from the limit hole.

[0067] It should be understood that a positioning protrusion is provided on the inner wall of the hollow post 121. The positioning protrusion can be provided at one end of the hollow post 121 located below the installation area 20. When the end of the linkage rod 123 abuts against the positioning protrusion, the linkage rod 123 is in the second working position, which can ensure the accurate position switching of the linkage rod 123.

[0068] There are various installation and cooperation methods between the hollow post 121 and the linkage rod 123. For example, see Figure 12 As shown, the hollow post 121 includes a cylinder body 1211 and an end cover 1212. The end cover 1212 is provided with a through hole, and the end cover 1212 is detachably connected to the cylinder body 1211. During assembly, the linkage rod 123 can be first inserted into the cylinder body 1211, and then the end cover 1212 can be installed at the mouth of the cylinder body 1211. Among them, the bottom of the cylinder body 1211 can be closed or provided with an opening. The bottom of the cylinder can be used as the positioning protrusion. See Figure 10 As shown, when the second limit post 12 is installed on the mounting seat 50, the end cover 1212 is located on the upper surface of the mounting seat 50.

[0069] Another example is that an opening is provided at one end of the hollow post 121 located above the installation area 20, and the opening communicates with the cavity. The linkage rod 123 is directly inserted into the cavity from the opening.

[0070] In some embodiments, see Figure 11 As shown, the linkage rod 123 can include a rod body 1231 and a pressing portion 1232, and the rod body 1231 and the pressing portion 1232 can be threadedly connected. During installation, the pressing portion 1232 can be connected to the rod body 1231 and then inserted into the cavity, or the rod portion can be first inserted into the cavity and then the pressing portion 1232 can be installed on the rod body 1231.

[0071] Illustratively, the cross-sectional area of the pressing portion 1232 is larger than the cross-sectional area of the rod body 1231 , which can ensure that the volume of the cavity is small, thereby reducing the outer diameter of the hollow column 121 . At the same time, when the staff manually touches the pressing portion 1232 , the contact area between the hand and the pressing portion 1232 is larger, and it is not easy to hurt the hand.

[0072] It should be noted that the linkage rod 123 may also be an integrally formed rod-shaped structure.

[0073] In some embodiments, the stopper 122 may be a ball. The ball's diameter is greater than the wall thickness of the hollow column 121, ensuring that the ball protrudes from the outer wall of the hollow column 121 when the linkage rod 123 is in the first position. The number of balls can be two, symmetrically arranged along the radial direction of the hollow column 121, to enhance the stopper effect.

[0074] In some embodiments, see Figure 11 As shown, the avoidance groove 12311 can be an annular groove. Along the axial direction of the linkage rod 123, the size of the annular groove opening is larger than the size of the groove bottom, and the groove wall of the annular groove forms a guiding slope to facilitate the ball to escape from the annular groove.

[0075] When the safety boots 10 need to be installed, the linkage rod 123 can be moved to the second work position first, and then the second limiting column 12 can be inserted into the second limiting hole 22. At this time, since the avoidance groove 12311 is connected to the mounting hole 12111, the limiting part 122 can be moved to the inside of the mounting hole 12111. The limiting part 122 can be pushed in manually, or the limiting part 122 can be pushed into the mounting hole 12111 after the hole wall of the second limiting hole 22 contacts the limiting part 122. Since the surface of the ball is spherical, it is easier to rotate flexibly, so that it can enter the mounting hole 12111 under the push of the hole wall of the second limiting hole 22.

[0076] After installation, the linkage rod 123 is moved to the first working position. During this process, the groove wall of the avoidance groove 12311 and the circumferential surface of the linkage rod 123 contact the surface of the ball, and push the ball out of the avoidance groove 12311, so that a part of the ball protrudes from the outer wall of the hollow column 121, and the protruding part can abut against the inner surface of the movable floor 30 to limit the separation of the second limiting column 12 and the second limiting hole 22.

[0077] In some embodiments, see Figure 11 and Figure 12As shown, the second limiting post 12 further includes a return spring 125. The return spring 125 is sleeved on the linkage rod 123. The linkage rod 123 is provided with a stop portion 124. A limiting boss 12112 is provided on the inner wall of the hollow column 121. One end of the return spring 125 abuts against the stop portion 124, and the other end of the return spring 125 abuts against the limiting boss 12112. The return spring 125 is used to switch the linkage rod 123 from the second working position to the first working position.

[0078] Exemplarily, the stop portion 124 is in a plate shape. The stop portion 124 can be fixedly connected to the rod body 1231. For example, the stop portion 124 and the rod body 1231 can be integrally formed, or can be fixedly connected by means of welding, bonding or threaded connection; of course, the stop portion 124 can also be integrally formed with the pressing portion 1232, or be fixedly connected to the pressing portion 1232 by means of welding, bonding or threaded connection.

[0079] In use, by pressing the pressing portion 1232, the linkage rod 123 is in the second working position. At this time, the return spring 125 undergoes elastic deformation, the avoidance groove 12311 communicates with the mounting hole 12111, and the limiting portion 122 can move into the mounting hole 12111. The second limiting post 12 is inserted into the second limiting hole 22. After installation, the pressing portion 1232 is released. Under the elastic force of the return spring 125, the linkage rod 123 moves to the first working position. At this time, a part of the ball protrudes from the outer side wall of the hollow column 121, and the protruding part can abut against the inner surface of the movable floor 30 to limit the separation of the second limiting post 12 from the second limiting hole 22.

[0080] Exemplarily, the return spring 125 can be a compression spring.

[0081] Of course, the return spring 125 can also not be provided, and the linkage rod 123 is switched from the second working position to the first working position by manually lifting the linkage rod 123.

[0082] It should be noted that a spring plunger can also be installed in the second limiting post 12.

[0083] In addition, it should be noted that the first limiting post 21 can also adopt the same or similar structure as the second limiting post 12.

[0084] In some embodiments, the limiting hole includes at least two sub-limiting holes, and the limiting post includes at least two sub-limiting posts; the shape of the sub-limiting hole is circular, and / or the cross-sectional shape of the sub-limiting post is circular. That is to say, when at least one of the shape of the sub-limiting hole and the cross-sectional shape of the sub-limiting post is circular, at least two sub-limiting holes and two sub-limiting posts are required to cooperate to realize the limiting of the safety boot 10 at a certain position.

[0085] Exemplarily, seeFigure 3 As shown, the sub-limiting holes in the first limiting hole 11 are named the first sub-limiting holes 111. The number of the first sub-limiting holes 111 is two, and the shape of the first sub-limiting holes 111 is circular. Correspondingly, referring to Figure 2 As shown, the sub-limiting posts in the first limiting post 21 are named the first sub-limiting posts 211. The number of the first sub-limiting posts 211 is two, and the shape of the cross-section of the first sub-limiting posts 211 is circular.

[0086] Referring to Figure 8 As shown, the sub-limiting holes in the second limiting hole 22 are named the second sub-limiting holes 221. The number of the second sub-limiting holes is two, and the shape of the second sub-limiting holes is circular. Correspondingly, the sub-limiting posts in the second limiting post 12 are named the second sub-limiting posts. The number of the second sub-limiting posts is two, and the shape of the cross-section of the second sub-limiting posts is circular. The structure of the second sub-limiting posts is the same as that of Figure 11 and Figure 12 the second limiting post 12 shown.

[0087] In other embodiments, the shape of the limiting hole is non-circular, and / or the shape of the cross-section of the limiting post is non-circular.

[0088] Taking the first limiting hole and the first limiting post as an example, the shape of the first limiting hole is rectangular, and the shape of the cross-section of the first limiting post is rectangular. At this time, through the cooperation of one first limiting hole and one first limiting post, the limiting function of the safety boots can be realized.

[0089] In one embodiment, the receiving port further includes a detection mechanism for detecting the position change of the safety boots 10. When the safety boots 10 deviate from the working position, the staff can be prompted to take corresponding measures through an alarm.

[0090] In some embodiments, the detection mechanism includes a ranging sensor. The ranging sensor is installed on the safety boots 10 and is used to detect the distance between the safety boots 10 and the wall surface where the front window of the receiving port is located.

[0091] Exemplarily, the ranging sensor can be a laser ranging sensor. For example, a diffuse reflection type laser ranging sensor can be used to direct the ranging laser beam towards the fuselage or the wall surface where the front window of the receiving port is located. This method is relatively reliable. It can also be considered to install the ranging sensor on the wall surface where the front window of the receiving port is located and direct it towards the safety boots.

[0092] For example, after the safety boot 10 is placed, the distance L1 between the safety boot 10 and the wall of the front window of the aircraft receiving port is recorded. Subsequently, the distance L2 between the safety boot 10 and the wall of the front window of the aircraft receiving port is continuously measured, and the change in relative distance ΔL from the aircraft receiving port is calculated, where ΔL = |L2 - L1|. For example, the following judgment rule can be used: if ΔL ≥ a set safety boot slippage alarm threshold, an alarm is triggered, such as a voice reminder: "Safety boots are abnormally displaced, please check."

[0093] It should be noted that a mirror-reflective laser ranging sensor can also be used. In this case, a mirror-reflective lens needs to be installed. One of the lens and the mirror-reflective ranging sensor is installed on the wall where the front window of the receiving port is located, and the other is installed on the safety boots.

[0094] In other embodiments, the detection mechanism includes a plurality of induction switches, which are spaced apart along the extension direction of the floor. For example, the induction switches may be, but are not limited to, infrared induction switches, microwave induction switches, ultrasonic induction switches, piezoelectric induction switches, electromagnetic induction switches, or capacitive induction switches.

[0095] For example, a plurality of induction switches may be arranged at intervals on the movable floor 30 along the extension and contraction direction of the movable floor 30. The number of induction switches triggered may be used to determine whether the safety boots 10 have been accidentally moved or placed in an abnormal position.

[0096] Exemplarily, the safety boots 10 are placed in the initial position. At the initial position, the number of sensing switches that the safety boots 10 can trigger is recorded as M, where M≥1 and M≤the total number of sensing switches. If all the sensing switches are not triggered at this time, an alarm will sound to remind you that "the position of the safety boots 10 is abnormal, please check."

[0097] Subsequently, the number of detection switches triggered by the safety boots 10 is continuously detected. For example, the following judgment rule can be adopted: if the number of sensing switches triggered by the safety boots 10 is not equal to M, an alarm reminder is triggered, such as a voice reminder: "The safety boots are abnormally displaced, please pay attention to check."

[0098] Of course, other judgment rules can also be used. For example, let's say there are five sensor switches, represented by S1, S2, S3, S4, and S5. The distance between two adjacent sensor switches is a set value. In the initial position, S1 and S2 are triggered. If S4 and S5 are triggered, an alarm will also be triggered. Different judgment rules are related to factors such as the number of sensor switches and the distance between them, which will not be described in detail here.

[0099] It should be understood that other judgment rules may also be adopted based on the same structure of the detection mechanism.

[0100] In addition, a certain judgment rule is set at the time of factory shipment, and the judgment rule can also be changed in actual applications to further improve the accuracy of the alarm.

[0101] This embodiment also provides a boarding bridge, including the receiving port provided in this embodiment.

[0102] For the boarding bridge provided in this embodiment, since the receiving port provided in this embodiment is used, through the cooperation of the limiting hole and the limiting column, the safety boot 10 can be installed in the installation area 20 of the receiving port, thereby reducing the possibility of the position of the safety boot 10 shifting, and further reducing the risk of damage to the aircraft cabin door.

[0103] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
