Description

Technical Field

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

[0002] After the boarding bridge docks with the aircraft, a safety shoe is usually installed at the arrival area of ​​the bridge to detect the aircraft door's descent and prevent the open aircraft door from colliding with the floor of the arrival area. Additionally, the area where the safety shoe is located should have protective measures to prevent accidental triggering, because if the safety shoe is accidentally touched during arrival, the boarding bridge may suddenly and rapidly descend, causing an accident.

[0003] In related technologies, a retractable guardrail structure is installed in this area, which is manually extended to the open aircraft door for protection. However, this guardrail structure is relatively complex, and if the aircraft door is closed before the guardrail is fully retracted, the door is prone to colliding with the guardrail and being damaged. Summary of the Invention

[0004] The purpose of this application is to provide a protective device, an access port, and a boarding bridge to reduce the risk of damage to the aircraft door while preventing the safety boot from being accidentally triggered.

[0005] For the purposes described above, this application provides a protective device, including a rotating shaft, a protective component, a guide portion, and a guide mating portion; The rotating shaft is used to install on the receiving port, and the axial direction of the rotating shaft is consistent with the height direction of the receiving port; one end of the protective member is hinged to the rotating shaft, and the protective member has a first station and a second station. At the first station, the other end of the protective member faces the floor of the receiving port, and at the second station, the other end of the protective member faces the aircraft door. The protective member is located on the side of the safety boot near the passage entrance of the receiving port. The guide portion is used to be installed in the receiving port. Along the width direction of the receiving port, the guide portion is located on the side of the rotating shaft away from the channel entrance of the receiving port, and the guide portion has a set guide profile; the guide mating portion is connected to the protective member and is located between the protective member and the guide portion; The guide portion is configured to guide the movement of the guide mating portion during the process of the protective member switching from the first station to the second station, so that the protective member rotates about the axis of the rotating shaft while being flipped and lifted from the first station in a direction away from the floor, so as to move towards the second station in a direction closer to the aircraft door; the guide mating portion and the guide portion cooperate to at least stop the protective member in the second station; If the protective member is squeezed by the aircraft door during the closing process, the protective member can rotate around the axis of the pivot to avoid the aircraft door.

[0006] In some embodiments of this application, the guide portion includes a first rod segment, a second rod segment, and a connecting segment. One end of the first rod segment is used to connect to the receiving port, the other end of the first rod segment is connected to one end of the connecting segment, the other end of the connecting segment is connected to one end of the second rod segment, and the other end of the second rod segment is used to connect to the receiving port. Along the height direction of the receiving port, the first pole segment is located above the second pole segment.

[0007] In some embodiments of this application, the connecting segment includes a first bent segment and a second bent segment, one end of the first bent segment is connected to the first rod segment, the other end of the first bent segment is connected to one end of the second bent segment, and the other end of the second bent segment is connected to the second rod segment.

[0008] In some embodiments of this application, the protective device further includes an elastic element, one end of which is connected to the receiving port, and the other end of which is connected to the rotating shaft to apply a preload force about its own axis to the rotating shaft so that the guide mating part remains in contact with the guide part, and the guide mating part can slide along the set guide contour. If the protective component is squeezed by the aircraft door during the closing process, the protective component can drive the rotating shaft to rotate against the preload of the elastic element in order to avoid the aircraft door.

[0009] In some embodiments of this application, the protective device further includes a first limiting part and a first limiting mating part, the first limiting part being installed on the rotating shaft and the first limiting mating part being installed on the protective member; at the second working position, the first limiting mating part cooperates with the first limiting part to keep the protective member at the second working position.

[0010] In some embodiments of this application, the protective device further includes a second limiting part and a second limiting mating part, the second limiting part being mounted on the rotating shaft and the second limiting mating part being mounted on the protective member; at the first working position, the second limiting part and the second limiting mating part cooperate to keep the protective member at the first working position.

[0011] In some embodiments of this application, the first limiting part includes an elephant trunk lock, and the first limiting mating part includes a hook, the hook engaging with the elephant trunk lock.

[0012] In some embodiments of this application, the protective device further includes a reciprocating drive mechanism, one end of which is hinged to the rotating shaft and the other end of which is hinged to the protective member, so as to drive the protective member to switch between the first station and the second station.

[0013] In some embodiments of this application, the protective device further includes a baffle fixedly connected to the rotating shaft, the baffle being used to shield at least a portion of the reciprocating drive mechanism.

[0014] In some embodiments of this application, there are multiple protective components, which are spaced apart along the height direction of the receiving port. Adjacent protective components are connected by a connecting rod so that the multiple protective components can move together.

[0015] In some embodiments of this application, the protective element is rod-shaped; And / or, a flexible material layer is provided on the circumferential outer surface of the protective component; And / or, the protective element is at least partially made of a flexible material.

[0016] For the purposes described above, this application also provides a receiving port, including the protective device described in any of the above embodiments.

[0017] For the purposes described above, this application also provides a boarding bridge, including the arrival port as described in any of the above embodiments.

[0018] This application has at least the following beneficial effects: The protective device provided in this application, through the coordinated operation of the rotating shaft, guide part, and guide mating part, allows the guide part to slide along a set guide contour during the process of the protective component switching from the first station to the second station. This enables the protective component to rotate around the axis of the rotating shaft and move towards the open aircraft door while flipping and lifting away from the floor, achieving a compound motion process. This ensures that the protective component is not blocked by the aircraft door when it starts to flip and lift from the first station, thus ensuring that the protective component can be smoothly switched to the second station. At this time, the guide mating part and the guide part work together to stop the protective component in the second station, preventing the protective component from continuing to rotate. At the same time, the other end of the protective component faces the aircraft door and is located on the side of the safety boot near the passage entrance, establishing a reliable physical barrier for the safety boot in the area that personnel must pass through, preventing accidents caused by accidental contact with the safety boot that could lead to a sudden and rapid descent of the boarding bridge.

[0019] Meanwhile, the protective device provided in this application has a flexible avoidance function. During the closing process of the aircraft cabin door, if the aircraft cabin door comes into contact with the protective component, the protective component can rotate around the axis of rotation when squeezed by the cabin door, thereby avoiding the aircraft cabin door, reducing the risk of damage to the aircraft cabin door, and improving the safety of the receiving process.

[0026] See Figures 1 to 9 As shown, this application embodiment provides an arrival port 10, including a protective device 20. The arrival port 10 has a floor 11 and a passageway 12, the passageway 12 corresponding to an aircraft door opening 32. A safety boot (not shown) is placed between the floor 11 and the open aircraft door 31. The arrival port 10 also includes a front upright plate 13 connected to the floor 11. The arrival port 10 is located near the aircraft 30 (…). Figure 9 The direction shown (of a portion of the aircraft fuselage) is defined as "forward," and the direction away from the aircraft 30 is defined as "rear"; along the height direction of the access port 10 (with... Figure 1 (The direction of the arrow D1 in the image is indicated by the arrow). The direction closer to the floor 11 is defined as "down", and the direction farther from the floor 11 is defined as "up". Along the width direction of the receiving port 10 (in the image), the direction closer to the floor 11 is defined as "down", and the direction farther from the floor 11 is defined as "up". Figure 1 (Indicated by arrow D2 in the diagram), the arrival port 10 has a left side and a rear side, with the front upright panel 13 located on the left and the passageway entrance 12 located on the right. The aircraft door 31, when open, is located near the left side of the arrival port 10, roughly corresponding to the front upright panel 13.

[0027] In some embodiments, see Figure 1 and Figure 2 As shown, the protective device 20 includes a rotating shaft 21, a protective component 22, a guide portion 23, a guide mating portion 24, and an elastic component 25; the rotating shaft 21 is used to install on the receiving port 10, and the axial direction of the rotating shaft 21 is aligned with the height direction of the receiving port 10; one end of the protective component 22 is hinged to the rotating shaft 21, and the protective component 22 has a first working position and a second working position. In the first working position, see... Figure 3 and Figure 4 As shown, the other end of the protective component 22 faces the floor 11 of the receiving port 10. See the second workstation. Figure 5 , Figure 6 and Figure 9 As shown, the other end of the protective member 22 faces the aircraft door 31, and the protective member 22 is located on the side of the safety boot near the passage entrance 12; the guide portion 23 is used to install on the receiving port 10, and along the width direction of the receiving port 10, the guide portion 23 is located on the side of the rotating shaft 21 away from the passage entrance 12, and the guide portion 23 has a set guide profile; the guide mating portion 24 is connected to the protective member 22 and is located between the protective member 22 and the guide portion 23; one end of the elastic member 25 is used to connect to the receiving port 10, and the other end of the elastic member 25 is connected to the rotating shaft 21 to apply a preload force to the rotating shaft 21 to rotate about its own axis, so that the guide mating portion 24 and the guide portion 23 are kept in contact, and the guide mating portion 24 is in contact with the guide portion 23. Part 24 can slide along a set guide profile; guide part 23 is configured to guide guide mating part 24 to move during the process of protective member 22 switching from the first station to the second station, so that protective member 22 rotates about the axis of rotating shaft 21 while flipping and lifting from the first station in a direction away from the floor 11, so as to move to the second station in a direction close to the aircraft door 31; guide mating part 24 and guide part 23 cooperate to at least stop protective member 22 in the second station; if protective member 22 is squeezed by aircraft door 31 during the closing of aircraft door 31, protective member 22 can drive rotating shaft 21 to overcome the preload of elastic member 25 and rotate to avoid aircraft door 31.

[0028] In this embodiment, the protective device 20, through the coordinated cooperation of the rotating shaft 21, the guide part 23, the guide mating part 24, and the elastic member 25, allows the guide part 23 to guide the guide mating part 24 to slide along a set guide contour during the process of the protective member 22 switching from the first station to the second station. This enables the protective member 22 to flip and rise away from the floor 11 while simultaneously rotating around the axis of the rotating shaft 21 in the first direction and moving towards the aircraft door 31, which is in the open state. This achieves a compound motion process, ensuring that the protective member 22 flips and rises from the first station. When the boarding bridge is raised, it will not be blocked by the aircraft door 31, thus ensuring that the protective component 22 can be smoothly switched to the second position. At this time, the guide mating part 24 and the guide part 23 cooperate to stop the protective component 22 in the second position, preventing the protective component 22 from continuing to rotate. At the same time, the other end of the protective component 22 faces the aircraft door 31, and the protective component 22 can be stably located on the side of the safety boot near the passage entrance 12, establishing a reliable physical barrier for the safety boot in the area that personnel must pass through, preventing the boarding bridge from suddenly and rapidly descending due to accidental contact with the safety boot.

[0029] Meanwhile, the protective device 20 in this embodiment has a flexible avoidance function. During the closing process of the aircraft door 31, if the aircraft door 31 comes into contact with the protective member 22, the protective member 22, when squeezed by the aircraft door 31, can drive the rotating shaft 21 to overcome the preload of the elastic member 25 and rotate in the second direction, thereby avoiding the aircraft door 31, reducing the risk of damage to the aircraft door 31, and improving the safety of the receiving process. The first direction is opposite to the second direction; for example, the first direction is counterclockwise and the second direction is clockwise.

[0030] When protection is needed, simply use external force to flip and lift the protective component 22 away from the floor 11. Under the pre-tightening force of the elastic component 25, the protective component 22 can slide smoothly along the set guide contour. The structure is simple, the operation is convenient, and it can ensure that the protective component 22 can smoothly reach the second working position. At the second working position, under the pre-tightening force of the elastic component 25 and the stopping action of the guide mating part 24 and the guide part 23, the protective component 22 can be stably held at the second working position, limiting its large swing, thereby achieving continuous protection for the safety boot, without affecting the normal passage of personnel.

[0031] When it is necessary to retract, simply use external force to flip and lower the protective part 22 towards the floor 11. The protective part 22 can still slide along the set guide contour until it returns to the first work station.

[0032] In some embodiments, the elastic element 25 can be a tension spring. One end of the tension spring is connected to the front end plate 13, and the other end of the tension spring is connected to the rotating shaft 21, with the connection point between the tension spring and the rotating shaft 21 offset from the axis of the rotating shaft 21. For example, along the front-rear direction of the receiving port 10 (with... Figure 1 (The arrow in the image indicates the direction of D3). The position where the tension spring connects to the rotating shaft 21 is located on the side of the axis of the rotating shaft 21 away from the front end plate 13.

[0033] See Figure 9 As shown, in practical application scenarios, after the boarding bridge connects to the aircraft, the aircraft door 31 opens. The open aircraft door 31 is close to the left side of the arrival port 10. However, due to differences in aircraft models, the left-right and front-back positions of different aircraft doors 31 relative to the arrival port 10 are not the same. Since the protective device 20 is installed at a fixed position on the front upright plate 13 of the arrival port 10, in order to better adapt to different aircraft models and ensure that the protective component 22 can open in place when the arrival port 10 connects to different aircraft models, this embodiment of the application uses the guide mating part 24 to slide along a set guide contour to form a compound curve motion trajectory of the protective component 22 from bottom to top and from right to left, thereby avoiding the obstruction of the aircraft door 31.

[0034] When protection is required, the operator can manually rotate the protective component 22 upwards to move it away from the first workstation. During this upward rotation, the rotating shaft 21, under the pre-tightening force provided by the elastic element 25, maintains close contact between the guide mating part 24 and the guide part 23. Because the guide part 23 has a defined guide profile, it guides the movement of the guide mating part 24, allowing the protective component 22 to rotate upwards from the first workstation (for example, the protective component rotates approximately to...). Figure 9 The position indicated by the dashed line (its free end roughly points towards the aircraft door opening 32) can also rotate around the axis of the pivot 21 and move towards the direction closer to the aircraft door 31 (i.e., from right to left). Figure 9 The arrow M in the figure represents the movement, thus forming a composite curve trajectory from bottom to top and from right to left.

[0035] Since the entire protective device 20 is not constrained in the rightward rotation direction (its leftward rotation is restricted by the guide part 23), if the aircraft door 31 collides with the protective component 22 during the process of closing from left to right (at this time, the protective component 22 may be in the second position or any position between the first and second positions), the protective component 22 can drive the rotating shaft 21 to overcome the preload of the elastic component 25 and rotate to the right along with the aircraft door 31 to avoid collision, thereby reducing the risk of damage to the aircraft door 31.

[0036] In some embodiments, see Figure 6 As shown, the protective member 22 is rod-shaped, and a flexible material layer 223 is provided on its circumferential outer surface. Compared with the retractable guardrail structure in related technologies, the rod-shaped protective member 22 has a simpler structure, smaller size, and is easier to operate. For example, the protective member 22 is round rod-shaped, which avoids direct contact between the aircraft door 31 and sharp corners or edges. At the same time, the flexible material layer 223 on the circumferential outer surface of the protective member 22 further protects the aircraft door 31. For example, the material of the flexible material layer 223 may include, but is not limited to, rubber.

[0037] In some embodiments, see Figure 6 As shown, the protective component 22 includes a first rod 221 and a second rod 222, which are integrally formed. The angle between the first rod 221 and the second rod 222 is an obtuse angle. For example, the length of the first rod 221 is greater than the length of the second rod 222, and a flexible material layer 223 is disposed on the circumferential outer surface of the first rod 221. The second rod 222 is hinged to the rotating shaft 21 via a pin 2111.

[0038] In some embodiments, the protective member 22 is at least partially made of a flexible material. For example, the first rod 221 is made of a flexible material, which may include, but is not limited to, rubber. In other embodiments, the protective member 22 may be entirely made of a flexible material.

[0039] This embodiment of the application further protects the aircraft door 31 by combining the buffering effect of the flexible material layer 223 with the mechanical structure avoidance, reducing the risk of damage to the aircraft door 31 due to accidental collision with the protective component 22.

[0040] In some embodiments, both ends of the rotating shaft 21 are mounted on the front end plate 13 via seated bearings. See also Figure 4 As shown, a pin seat 211 is fixedly connected between the two ends of the rotating shaft 21, for example, the pin seat 211 is welded to the rotating shaft 21; the pin seat 211 is equipped with a pin 2111, one end of the protective member 22 is hinged to the rotating shaft 21 through the pin 2111, and the other end of the protective member 22 is a free end. In the first station, the free end faces the floor 11 of the receiving port 10, and at this time, the protective member 22 is generally perpendicular to the floor 11; in the second station, the free end faces the aircraft door 31, and at this time, the protective member 22 is generally parallel to the floor 11, that is, the protective member 22 is placed horizontally between the receiving port 10 and the aircraft door 31, and is located on the side of the safety boot near the passage entrance 12 to protect the safety boot.

[0041] In some embodiments, see Figure 2As shown, the guide section 23 includes a first rod segment 231, a second rod segment 232, and a connecting segment 233. One end of the first rod segment 231 is used to connect to the receiving port 10, and the other end of the first rod segment 231 is connected to one end of the connecting segment 233. The other end of the connecting segment 233 is connected to one end of the second rod segment 232, and the other end of the second rod segment 232 is used to connect to the receiving port 10. Along the height direction of the receiving port 10, the first rod segment 231 is located above the second rod segment 232.

[0042] See Figure 2 As shown, one end of the first rod segment 231 is used for fixed connection with the front upright plate 13. The first rod segment 231, the connecting segment 233, and the second rod segment 232 are integrally formed. The other end of the second rod segment 232 is used for fixed connection with the front upright plate 13. The fixed connection can be achieved by welding or by fasteners, including bolts and nuts. For example, the first rod segment 231, the second rod segment 232, and the connecting segment 233 are all round rods. The guide part 23 can be formed by bending a single round rod. The structure is simple, easy to process, and the overall structure is more stable, providing a smooth guiding effect for the movement of the protective component 22. The connecting segment 233 is a bent rod, which includes a first bent segment 2331 and a second bent segment 2332. One end of the first bent segment 2331 is connected to the first rod segment 231, and the other end of the first bent segment 2331 is connected to one end of the second bent segment 2332. The other end of the second bent segment 2332 is connected to the second rod segment 232. For example, the circumferential surfaces of the second rod segment 232, the second bent segment 2332, and the first bent segment 2331 that contact the guide mating part 24 form a set guide profile.

[0043] By dividing the guide section 23 into a first rod segment 231 located at the top, a second rod segment 232 located at the bottom, and a connecting section 233 located between the two, and the second rod segment 232 located at the bottom is closer to the pivot 21 in the width direction of the receiving port 10 than the first rod segment 231, and then transitionally connected by the first bending section 2331 and the second bending section 2332, a guide track extending from bottom to top and gradually away from the pivot 21 (i.e. from right to left) is constructed in three-dimensional space. When the protective member 22 flips upward, the guide mating part 24 slides smoothly along the guide track from the second rod segment 232 through the second bending section 2332 and then back to the first bending section 2331 under the pre-tightening force of the elastic member 25. Without the need for a complex mechanism, the protective member 22 can smoothly achieve the composite movement of lifting and swinging laterally to the left at the same time by forming a set guide contour through the arrangement of multiple rod segments in space.

[0044] It should be noted that the structure of the guide section 23 and the setting guide profile are not limited to the above one. Other setting guide profiles can also be constructed according to actual needs. For example, part of the circumferential surface of the first rod segment 231 can also form part of the setting guide profile.

[0045] It should be understood that the protective component 22 can be folded inward and downward to save space when switched to the low position (first station), and can be opened outward to provide a larger protection range when switched to the high position (second station). At the same time, the smooth transition of the connecting section 233 can ensure the smooth operation of the protective device 20 during operation.

[0046] In some embodiments, see Figure 8 As shown, the guide mating part 24 includes a cylindrical structure 241 and a mounting rod 242. The cylindrical structure 241 is connected to the second rod body 222 through the mounting rod 242. For example, the cylindrical structure 241 can be a roller. When the roller slides along the set guide contour, it can rotate around its own axis to reduce frictional resistance and improve the smoothness of movement.

[0047] In some embodiments, see Figure 6 and Figure 8 As shown, the protective device 20 also includes a first limiting part 26 and a first limiting mating part 27. The first limiting part 26 is installed on the rotating shaft 21, and the first limiting mating part 27 is installed on the protective member 22. At the second working position, the first limiting mating part 27 cooperates with the first limiting part 26 to keep the protective member 22 at the second working position.

[0048] For example, the first limiting part 26 can be installed on the rotating shaft 21 by welding, bonding, fastening, or other means, and the first limiting part 26 is located above the pin 2111. The first limiting mating part 27 can be installed on the second rod body 222 by welding, bonding, fastening, or other means.

[0049] By installing a first limiting part 26 on the rotating shaft 21 and a corresponding first limiting mating part 27 on the protective part 22, when the protective part 22 moves from the first station to the second station, the first limiting mating part 27 can cooperate with the first limiting part 26 to prevent the protective part 22 from continuing to move upward or falling under its own weight. This allows the protective part 22 to be stably and reliably maintained in the second station, reducing the phenomenon of displacement or loosening of the protective part 22 due to environmental wind force, passenger collision or equipment vibration, and improving the safety and stability of the protective device 20 in the airport reception protection state.

[0050] For example, the first limiting part 26 can be an elephant trunk lock, which can be equipped with rollers; the first limiting mating part 27 can be a hook, which can engage with the elephant trunk lock, and the rollers on the elephant trunk lock can be used to achieve a smooth transition when locking and unlocking.

[0051] In some embodiments, see Figure 4 As shown, the protective device 20 also includes a second limiting part 28 and a second limiting mating part 29. The second limiting part 28 is installed on the rotating shaft 21, and the second limiting mating part 29 is installed on the protective member 22. At the first working position, the second limiting part 28 and the second limiting mating part 29 cooperate to keep the protective member 22 at the first working position.

[0052] For example, the second limiting part 28 can be installed on the rotating shaft 21 by welding, bonding, fastener connection, or other means, and the second limiting part 28 is located below the pin 2111. The second limiting mating part 29 can be installed on the second rod body 222 by welding, bonding, fastener connection, or other means, and the second limiting mating part 29 and the first limiting mating part 27 are located on opposite sides of the second rod body 222. To facilitate the installation of the first limiting mating part 27 and the second limiting mating part 29, two opposing mounting planes can be provided on the second rod body 222. The first limiting mating part 27 is installed on the mounting plane near the first limiting part 26, and the second limiting mating part 29 is installed on the mounting plane near the second limiting part 28.

[0053] By installing a second limiting part 28 on the rotating shaft 21 and a corresponding second limiting mating part 29 on the protective part 22, when the protective part 22 is in the first working position, the second limiting mating part 29 can cooperate with the second limiting part 28 to prevent the protective part 22 from swinging up and down, thereby enabling the protective part 22 to be stably and reliably maintained in the first working position.

[0054] For example, the second limiting part 28 can be an elephant trunk lock, which can be equipped with rollers; the second limiting mating part 29 can be a hook, which can engage with the elephant trunk lock, and the rollers on the elephant trunk lock can be used to achieve a smooth transition when locking and unlocking.

[0055] It should be understood that the structure and working principle of the elephant trunk lock and the elephant trunk lock with rollers are things that 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 describe them in detail.

[0056] When passengers have finished boarding and disembarking and the boarding bridge needs to be removed, the staff will unlock the first limiting engagement part 27 and the first limiting part 26, and rotate the protective part 22 downward until the second limiting engagement part 29 and the second limiting part 28 are locked together, thereby fixing the protective part 22. At this time, the aircraft cabin door 31 can be closed normally.

[0057] In other embodiments, the protective member 22 can also be rotatably connected to the rotating shaft 21 via a damping rotating shaft. Under the action of the damping rotating shaft, the protective member 22 can be held in the first or second position.

[0058] In some embodiments, there are multiple protective elements 22, which are spaced apart along the height direction of the arrival port 10. Adjacent protective elements 22 are connected by a connecting rod 220, allowing the multiple protective elements 22 to move together. The number of pins 2111 is the same as the number of protective elements 22, and they are connected one-to-one. During operation, the operator can drive at least one of the protective elements 22 to drive all the protective elements 22 to move synchronously via the connecting rod 220, improving the integrity and convenience of the protective device 20 when switching work positions. At the same time, since the multiple protective elements 22 are spaced apart along the height direction of the arrival port 10, in the second work position, it is equivalent to increasing the total protective area in the height direction of the arrival port 10, which helps prevent passengers or staff of different heights or with different accidental contact behaviors from accidentally entering the safety boot area, thereby providing a more comprehensive safety barrier and further enhancing the safety of the arrival process.

[0059] See Figures 10 to 15 As shown, there are two protective members 22, spaced apart axially along the shaft 21. Each protective member 22 is connected to a corresponding pin seat 211. The length of the second rod 222 of the upper protective member 22 is greater than that of the second rod 222 of the lower protective member 22, allowing the first rods 221 of the two protective members 22 to be substantially parallel. One end of the connecting rod 220 is hinged to the upper second rod 222, and the other end of the connecting rod 220 is hinged to the lower second rod 222. See also... Figure 11 and Figure 13 As shown, at the first workstation, two protective components 22 are arranged side by side. (See attached image) Figure 14 and Figure 15 As shown, at the second workstation, two protective components 22 are arranged parallel to each other at intervals along the height direction of the machine inlet 10.

[0060] In some embodiments, see Figures 16 to 21 As shown, the protective device 20 also includes a reciprocating drive mechanism 201. One end of the reciprocating drive mechanism 201 is hinged to the rotating shaft 21, and the other end of the reciprocating drive mechanism 201 is hinged to the protective member 22 to drive the protective member 22 to switch between the first station and the second station.

[0061] For example, one end of the reciprocating drive mechanism 201 is hinged to the rotating shaft 21 below the pin seat 211, and the other end of the reciprocating drive mechanism 201 is hinged to the second rod 222 of the protective member 22. By driving the protective member 22 between the first and second workstations through the reciprocating drive mechanism 201, manual operation can be eliminated, the labor intensity of the workers can be reduced, and the automation of the receiving operation can be achieved.

[0062] The reciprocating drive mechanism 201 has mechanical self-locking, hydraulic or pneumatic holding characteristics, which can provide positioning and support force for the protective part 22, so that it can be stably held in the corresponding working position. This eliminates the need for the first limiting part 26, the first limiting mating part 27, the second limiting part 28 and the second limiting mating part 29.

[0063] In some embodiments, the reciprocating drive mechanism 201 may be an electric actuator, see [reference needed]. Figure 21 As shown, when the electric push rod extends, it causes the protective member 22 to leave the first station. During the upward rotation of the protective member 22, the rotating shaft 21, under the preload provided by the elastic member 25, keeps the guide mating part 24 and the guide part 23 in close contact. Since the guide part 23 has a set guide profile, it can guide the movement of the guide mating part 24, so that while the protective member 22 rotates upward from the first station, it can also rotate around the axis of the rotating shaft 21 and move towards the direction closer to the aircraft door 31 (i.e., from right to left), thus forming a compound curve motion trajectory from bottom to top and from right to left.

[0064] When it is necessary to retrieve protective component 22, see [link / reference]. Figure 17 As shown, the electric push rod retracts, causing the protective component 22 to flip and fall towards the floor 11. The protective component 22 can still slide along the set guide contour until it returns to the first working position.

[0065] Because the electric push rod has built-in extension and retraction limit switches, it can send corresponding status signals to the boarding bridge control system when it is extended or retracted to the correct position, so that the boarding bridge can perform the corresponding operation.

[0066] In other embodiments, the reciprocating drive mechanism 201 may also be a cylinder or a hydraulic cylinder, or a linear reciprocating drive mechanism such as a lead screw and nut.

[0067] In some embodiments, see Figure 17 , Figure 19 and Figure 21As shown, the protective device 20 also includes a baffle 202, which is fixedly connected to the rotating shaft 21. The baffle 202 is used to cover at least a portion of the reciprocating drive mechanism 201. During the telescopic movement of the reciprocating drive mechanism 201, the baffle 202 can block external vision and close mechanical gaps, effectively preventing passengers or staff from putting their hands or other body parts into the movement range of the reciprocating drive mechanism 201, thereby reducing the risk of personnel being pinched. While ensuring the automated operation of the boarding bridge, it also achieves personnel safety protection.

[0068] It should be understood that since the baffle 202 is fixedly connected to the rotating shaft 21, the baffle 202 rotates together with the rotating shaft 21. If the aircraft door 31 collides with the protective component 22 during the process of closing from left to right, the protective component 22 can drive the rotating shaft 21 to overcome the preload of the elastic component 25 and rotate. It will follow the thrust of the aircraft door 31 and rotate to the right to avoid the collision. During the process of avoiding the collision to the right, the baffle 202 will not obstruct the rotation of the rotating shaft 21, thereby reducing the risk of damage to the aircraft door 31.

[0069] In some embodiments, there are two protective members 22, which are connected by a connecting rod 220 so that the two protective members 22 can move together; see also Figure 22 As shown, at the first workstation, two protective components 22 are arranged side by side. (See attached image) Figure 23 As shown, at the second workstation, two protective components 22 are spaced apart along the height direction of the machine inlet 10.

[0070] It should be noted that the number of protective components 22 can also be three or more. Adjacent protective components 22 are connected by a connecting rod 220, which will not be described in detail here.

[0071] In some embodiments, the elastic element 25 may be omitted. Specifically, the protective device 20 includes a rotating shaft 21, a protective element 22, a guide portion 23, and a guide mating portion 24; the rotating shaft 21 is used to install on the receiving port 10, and the axial direction of the rotating shaft 21 is aligned with the height direction of the receiving port 10; one end of the protective element 22 is hinged to the rotating shaft 21, and the protective element 22 has a first working position and a second working position. In the first working position, the other end of the protective element 22 faces the floor 11 of the receiving port 10, and in the second working position, the other end of the protective element 22 faces the aircraft door 31, and the protective element 22 is located on the side of the safety boot near the passage entrance 12 of the receiving port 10; the guide portion 23 is used to install on the receiving port 10, and along the width direction of the receiving port 10, the guide portion 23 is located on the side of the rotating shaft 21 away from the passage entrance 12 of the receiving port 10, guiding... The guide portion 23 has a set guide profile; the guide mating portion 24 is connected to the protective member 22 and is located between the protective member 22 and the guide portion 23; the guide portion 23 is configured to guide the guide mating portion 24 to move during the process of the protective member 22 switching from the first station to the second station, so that the protective member 22 rotates about the axis of the pivot 21 while flipping and lifting from the first station in a direction away from the floor 11, so as to move towards the second station in a direction close to the aircraft door 31; the guide mating portion 24 and the guide portion 23 cooperate to at least stop the protective member 22 in the second station; if the protective member 22 is squeezed by the aircraft door 31 during the closing of the aircraft door 31, the protective member 22 can rotate about the axis of the pivot 21 to avoid the aircraft door 31.

[0072] The protective device 20 provided in this embodiment, through the coordinated cooperation of the rotating shaft 21, the guide part 23, and the guide mating part 24, allows the guide part 23 to guide the guide mating part 24 to slide approximately along a set guide contour during the process of the protective component 22 switching from the first station to the second station. This enables the protective component 22 to rotate around the axis of the rotating shaft 21 and move towards the aircraft door 31, which is in the open state, while flipping and lifting away from the floor 11. This achieves a compound motion process, ensuring that the protective component 22 is not blocked by the aircraft door 31 when it starts to flip and lift from the first station, thus ensuring that the protective component 22 can be smoothly switched to the second station. At this time, the guide mating part 24 and the guide part 23 cooperate to stop the protective component 22 in the second station, preventing the protective component 22 from continuing to rotate. At the same time, the other end of the protective component 22 faces the aircraft door 31 in the open state and is located on the side of the safety boot near the passage entrance 12, establishing a reliable physical barrier for the safety boot in the area that personnel must pass through, preventing accidents caused by accidental contact with the safety boot that could lead to a sudden and rapid descent of the boarding bridge.

[0073] Meanwhile, the protective device 20 has a flexible avoidance function. During the closing process of the aircraft door 31, if the aircraft door 31 comes into contact with the protective component 22, the protective component 22 can rotate around the axis of the rotating shaft 21 when it is squeezed by the door, thereby avoiding the aircraft door 31, reducing the risk of damage to the aircraft door 31, and improving the safety of the receiving process.

[0074] It should be understood that during the manual upward rotation of the protective component 22 by the operator, a force can be applied to the protective component 22 towards the guide portion 23, so that the guide mating portion 24 and the guide portion 23 remain in contact. This allows the guide mating portion 24 to slide along the set guide contour, forming a compound curve motion trajectory for the protective component 22 from bottom to top and from right to left, thus avoiding the obstruction of the aircraft door 31. To ensure that the protective component 22 can be relatively stably positioned in the second working position, the rotating shaft 21 has a certain damping function to limit the large-amplitude swing of the protective component 22 around the axis of the rotating shaft 21. It should be noted that in actual working conditions, the protective component 22 can be allowed to swing slightly with the rotating shaft 21. Under the premise that the protective component 22 can continuously protect the safety boot and does not affect personnel passage, the damping force should be as small as possible. This allows the protective component 22 to smoothly rotate around the axis of the rotating shaft 21 to avoid the aircraft door 31 when it comes into contact with and is squeezed.

[0075] In the embodiment where the protective device 20 also includes a reciprocating drive mechanism 201, the center of gravity of the reciprocating drive mechanism 201 is biased toward the guide portion 23, thereby enabling the rotating shaft 21 to rotate around its own axis toward the guide portion 23, thereby causing the guide mating portion 24 to fit against the guide portion 23 and slide along the set guide contour.

[0076] The receiving port 10 provided in this application embodiment includes the protective device 20 in any of the above embodiments. Since the protective device 20 has the above-mentioned technical effects, the receiving port 10 also has corresponding technical effects, which will not be described in detail here.

[0077] This application also provides a boarding bridge, including the arrival port 10 provided in any of the above embodiments.

[0078] The boarding bridge provided in this embodiment uses the arrival port 10 provided in any of the above embodiments. When the boarding bridge connects to the aircraft, the aircraft door 31 opens. The open aircraft door 31 is located near the left side of the arrival port 10. Through the coordinated cooperation of the pivot 21, the guide part 23, and the guide mating part 24, during the process of the protective member 22 switching from the first station to the second station, the guide part 23 can guide the guide mating part 24 to slide along the set guide contour. This allows the protective member 22 to rotate around the axis of the pivot 21 and move towards the open aircraft door 31 while flipping and lifting away from the floor 11. The composite motion process is realized, ensuring that the protective component 22 will not be blocked by the aircraft door 31 when it starts to flip and lift from the first station, thus ensuring that the protective component 22 can be smoothly switched to the second station. At this time, the guide mating part 24 and the guide part 23 cooperate to stop the protective component 22 in the second station, preventing the protective component 22 from continuing to rotate. At the same time, the other end of the protective component 22 faces the aircraft door 31, and the protective component 22 can be stably located on the side of the safety boot near the passage entrance 12, establishing a reliable physical barrier for the safety boot in the area that personnel must pass through, preventing the boarding bridge from suddenly and rapidly descending due to accidental contact with the safety boot.

[0079] Meanwhile, the protective device 20 in this embodiment has a flexible avoidance function. During the closing process of the aircraft door 31, if the aircraft door 31 comes into contact with the protective member 22, the protective member 22 can rotate around the axis of the rotating shaft 21 when it is squeezed by the door, thereby avoiding the aircraft door 31, reducing the risk of damage to the aircraft door 31, and improving the safety of the receiving process.

[0080] When protection is needed, simply use external force to flip and lift the protective component 22 away from the floor 11. The protective component 22 can slide roughly along the set guide contour. The structure is simple, the operation is convenient, and it can ensure that the protective component 22 can smoothly reach the second work station.

[0081] When it is necessary to retract, simply use external force to flip and lower the protective component 22 towards the floor 11. The protective component 22 can still slide roughly along the set guide contour until it returns to the first work station.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
