[0036] See Figures 1 to 10As shown in the figure, this embodiment provides a safety boot 10, which includes a mounting base 11, a holding handle 12, and a limiting component 13. The holding handle 12 is connected to the mounting base 11. The limiting component 13 includes a limiting member 131, which has a first end and a second end. The part between the two ends of the limiting member 131 is rotatably connected to the mounting base 11. The first end of the limiting member 131 has a first working position and a second working position. In the first working position, the first end of the limiting member 131 is used to cooperate with the limiting part of the access port, so that the safety boot 10 is installed on the access port. In the second working position, the first end of the limiting member 131 can be separated from the limiting part of the access port. The second end of the limiting member 131 can move relative to the holding handle 12, so that the first end of the limiting member 131 can be switched between the first working position and the second working position.

[0037] For the safety boot 10 provided in this embodiment, during use, the second end of the limiting member 131 can be first driven to move relative to the holding handle 12, so that the first end of the limiting member 131 is in the second working position. Then, the safety boot 10 is placed at the corresponding position of the access port, so that the first end of the limiting member 131 is aligned with the limiting part. Then, the second end of the limiting member 131 is further driven to move relative to the holding handle 12, so that the first end of the limiting member 131 is in the first working position. At this time, the first end of the limiting member 131 cooperates with the limiting part of the access port, thereby installing the safety boot 10 on the access port, reducing the possibility of the position of the safety boot 10 shifting, and further reducing the risk of damage to the aircraft cabin door.

[0038] Generally, the second end of the limiting member 131 is manually driven to move relative to the holding handle 12. Of course, an electric or other means can also be used to drive the second end of the limiting member 131 to move relative to the holding handle 12.

[0039] Exemplarily, the safety boot 10 provided in this embodiment can be a mobile safety boot, and the working position of the mobile safety boot can be selected according to different styles of aircraft cabin doors. In the access state, it can prevent the opened aircraft cabin door from scraping against the floor of the access port. Specifically, when the boarding bridge is docked to the aircraft and the aircraft cabin door is opened, the staff will place the safety boot 10 under the opened aircraft cabin door, such as directly below. Before the aircraft cabin door is closed, the staff will take away the safety boot 10 from under the aircraft cabin door. Generally, the safety boot 10 is placed in a storage box for storage.

[0040] Exemplarily, the safety boot 10 can be placed in the area between the floor of the access port and the bottom of the aircraft cabin door to protect the aircraft cabin door.

[0041] In one embodiment, the first end of the limiting member 131 is bent to form a limiting cooperation part, which is used to cooperate with the limiting part to limit the mounting base 11 to be installed on the access port.

[0042] For example, see Figure 2 As shown, the limiting member 131 is in the shape of a bent plate, and the limiting member 131 includes a first plate portion 1311, a second plate portion 1312, and a third plate portion 1313. The first plate portion 1311 and the second plate portion 1312 extend to both sides of the third plate portion 1313, respectively. Exemplarily, the first plate portion 1311 and the second plate portion 1312 are parallel, and the first plate portion 1311 and the third plate portion 1313 are perpendicular. The first plate portion 1311 forms a limiting matching portion for matching with the limiting portion.

[0043] Exemplarily, the first plate portion 1311 , the second plate portion 1312 and the third plate portion 1313 may be integrally formed. The first end of the stopper 131 is the free end of the first plate portion, and the second end of the stopper 131 is the end of the second plate portion 1312 away from the third plate portion 1313 .

[0044] A mounting hole is provided at the corner connection between the second plate portion 1312 and the third plate portion 1313, and the mounting hole can be a through hole or a blind hole; the mounting seat 11 is provided with a rotating shaft 111, and the rotating shaft 111 is passed through the mounting hole, and the limiting member 131 can rotate around the axis of the rotating shaft 111 to be rotatably connected with the mounting seat 11. Exemplarily, the rotation of the limiting member 131 can be achieved by toggling the second plate portion 1312.

[0045] In one embodiment, a gripping portion 132 is disposed at the second end of the limiting member 131 , and a gap is provided between the gripping portion 132 and the outer surface of the gripping handle 12 so that the second end of the limiting member 131 can move relative to the gripping handle 12 .

[0046] See also Figure 2 As shown, the gripping portion 132 is fixedly connected to the second plate portion 1312. For example, the gripping portion 132 and the second plate portion 1312 can be welded or integrally formed.

[0047] When the safety boot 10 needs to be placed, the gripping portion 132 and the gripping handle 12 can be held simultaneously to rotate the stopper 131 around the axis of the rotating shaft 111. For example, see Figure 2 As shown, the limiting member 131 rotates counterclockwise around the axis of the rotating shaft 111, so that the first plate portion 1311 moves toward the direction of abutting the holding handle 12, so that the safety boot 10 can be placed at the position of the receiving port for placing the safety boot 10, so that the free end of the first plate portion 1311 is aligned with the limiting portion, and the holding handle 12 is released, so that the limiting member 131 rotates clockwise around the axis of the rotating shaft 111, so that the limiting matching portion cooperates with the limiting portion, and the placement of the safety boot 10 is completed.

[0048] When it is necessary to take away the safety boots 10, the holding part 132 and the holding handle 12 can be held simultaneously, so that the limiting part 131 rotates around the axis of the rotating shaft 111. Exemplarily, the limiting part 131 rotates counterclockwise around the axis of the rotating shaft 111, so that the limiting cooperation part is separated from the limiting part, and thus the safety boots 10 can be taken away.

[0049] In one embodiment, referring to Figure 2 and Figure 4 As shown, the holding handle 12 is cylindrical; the holding part 132 is in the shape of an arc-shaped plate, and the axial direction of the holding part 132 is consistent with the axial direction of the holding handle 12; the holding part 132 is located below the holding handle 12, and along the axial direction of the holding part 132, the size of the holding part 132 is larger than the size of the limiting part 131.

[0050] Exemplarily, along the axial direction of the holding part 132, the sizes of the first plate part 1311, the second plate part 1312 and the third plate part 1313 are all smaller than the size of the holding part 132, which is convenient for holding the holding part 132 for operation.

[0051] Exemplarily, the widths of the first plate part 1311, the second plate part 1312 and the third plate part 1313 can be equal.

[0052] In other embodiments, the holding part 132 can also be located above the holding handle 12.

[0053] It should be noted that the structure of the holding part 132 is not limited to the arc-shaped plate. For example, the holding part 132 can also be a straight plate structure.

[0054] In one embodiment, referring to Figure 2 As shown, the limiting component 13 further includes a resetting member 133. One end of the resetting member 133 is connected to the mounting seat 11, and the other end of the resetting member 133 is connected to the limiting part 131. The resetting member 133 is used to switch the first end of the limiting part 131 from the second working position to the first working position.

[0055] By providing the resetting member 133, automatic reset of the limiting part 131 can be achieved, the placement speed of the safety boots 10 is increased, and thus the receiving efficiency of the boarding bridge can be improved.

[0056] Specifically, when the staff holds the holding handle 12 and the holding part 132, the first end of the limiting part 131 is in the second working position, and the resetting member 133 can undergo elastic deformation to store energy; when the staff releases the holding handle 12 and the holding part 132, the resetting member 133 releases energy, drives the limiting part 131 to rotate, and makes the second end of the limiting part 131 in the first working position.

[0057] Exemplarily, the reset member 133 in this embodiment may be a tension spring. A hanging ring is provided on the lower surface of the second plate portion, and a connecting post is provided on the mounting seat. One end of the tension spring is connected to the connecting post, and the other end of the tension spring is connected to the hanging ring.

[0058] In other embodiments, the reset member 133 may also be a torsion spring or a compression spring. By adjusting the installation position of the reset member 133, the function of switching the first end of the limiting member 131 from the second working position to the first working position can also be achieved.

[0059] In one embodiment, referring to Figure 2 、 Figure 7 and Figure 10 as shown, the number of the limiting assemblies 13 is two, and the two limiting assemblies 13 are oppositely arranged on both sides of the holding handle 12. Each limiting assembly 13 is respectively matched with the corresponding limiting portion, so as to enhance the fixing effect on the safety boot 10.

[0060] This embodiment also provides a receiving port, which includes a limiting seat 21 and the safety boot 10 provided in this embodiment. The limiting seat 21 is provided with a limiting portion. Referring to Figures 5 to 7 as shown, in the first working position, the first end of the limiting member 131 can be matched with the limiting portion, so that the safety boot 10 is installed on the limiting seat 21; referring to Figures 8 to 10 as shown, in the second working position, the first end of the limiting member 131 can be separated from the limiting portion of the receiving port, so that the safety boot 10 is separated from the limiting seat 21.

[0061] For the receiving port provided in this embodiment, since the safety boot 10 provided in this embodiment is used, when docking with the aircraft, the second end of the limiting member 131 can be driven to move relative to the holding handle 12 first, so that the first end of the limiting member 131 is in the second working position. Then, the safety boot 10 is placed at the corresponding position of the receiving port, so that the first end of the limiting member 131 is aligned with the limiting portion. Then, the second end of the limiting member 131 is driven to move relative to the holding handle 12 again, so that the first end of the limiting member 131 is in the first working position. At this time, the first end of the limiting member 131 is matched with the limiting portion, thereby installing the safety boot 10 on the limiting seat 21, reducing the possibility that the position of the safety boot 10 deviates, and further reducing the risk of damage to the aircraft cabin door.

[0062] In one embodiment, referring to Figure 2 as shown, the limiting portion includes a limiting hole 2111, and the limiting and matching portion is a plug board, that is, the first plate portion 1311; in the first working position, the first plate portion 1311 is inserted into the limiting hole 2111, and in the second working position, the first plate portion 1311 is separated from the limiting hole 2111.

[0063] The limiting hole 2111 may be a through hole or a blind hole.

[0064] In one embodiment, the aircraft docking port further includes a movable floor 22, and the limit seat 21 is installed on the movable floor 22; the number of limit holes 2111 is multiple, and the multiple limit holes 2111 are arranged at intervals along the length direction of the limit seat 21, wherein the length direction of the limit seat 21 is consistent with the telescopic direction of the movable floor 22.

[0065] Exemplarily, the limit seat 21 can be installed on the movable floor 22 through fasteners, and the fasteners can include bolts and nuts. The multiple limit holes 2111 are arranged at intervals along the length direction of the limit seat 21, so that the safety boots 10 can be placed at different positions, that is to say, along the length direction of the limit seat 21, there are multiple positions for the safety boots 10 to be placed to adapt to different types of aircraft hatches.

[0066] In the state where the aircraft docking port is in contact with the aircraft, the length direction of the limit seat 21 faces the aircraft hatch.

[0067] In one embodiment, referring to Figure 2 As shown, the limit seat 21 is provided with a receiving groove 211, and the limit holes 2111 are provided on the groove wall of the receiving groove 211.

[0068] The safety boot 10 further includes a bottom plate 14, and the bottom plate 14 is connected to the mounting seat 11. Exemplarily, the bottom plate 14 is perpendicular to the mounting seat 11; the width of the bottom plate 14 is adapted to the width of the receiving groove 211, and the two groove walls of the receiving groove 211 can also play a role in limiting the safety boot 10. In addition, when it is necessary to adjust the position of the safety boot 10, it is also convenient to slide the safety boot 10 along the extension direction of the receiving groove 211.

[0069] In one embodiment, the number of the limiting components 13 is two, and the two limiting components 13 are oppositely arranged on both sides of the holding handle 12; the number of the limiting parts is two, and the two limiting parts are respectively matched with the two limiting components 13.

[0070] Each limiting part includes multiple limiting holes 2111, and the multiple limiting holes 2111 are arranged at intervals along the extension direction of the groove wall of the receiving groove 211.

[0071] In one embodiment, the aircraft docking port further includes a detection mechanism for detecting the position change of the safety boot 10. When the safety boot 10 deviates from the working position, it can prompt the staff to take corresponding measures through an alarm.

[0072] In some embodiments, the detection mechanism includes a distance measuring sensor, and the distance measuring sensor is installed on the safety boot 10, and the distance measuring sensor is used to detect the distance between the safety boot 10 and the wall surface where the front window of the aircraft docking port is located.

[0073] Exemplarily, the ranging sensor can be a laser ranging sensor. For example, a diffuse reflection type laser ranging sensor can be adopted to direct the ranging laser beam towards the wall surface where the fuselage or the front window of the access 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 access port is located and direct it towards the safety boots.

[0074] Exemplarily, after the safety boots 10 are placed, record the current distance L1 between the safety boots 10 and the wall surface where the front window of the access port is located. Subsequently, continuously detect the distance L2 between the safety boots 10 and the wall surface where the front window of the access port is located, and calculate the relative distance change value ΔL of the access port, ΔL = |L2 - L1|. For example, the following judgment rule can be adopted: If ΔL ≥ the set alarm threshold for safety boot sliding, trigger an alarm reminder, such as a voice reminder: "The safety boots have abnormal displacement, please check."

[0075] It should be noted that a specular reflection type laser ranging sensor can also be adopted. At this time, a specular reflection lens needs to be installed. One of the lens and the specular reflection type ranging sensor is installed on the wall surface where the front window of the access port is located, and the other is installed on the safety boots.

[0076] In some other embodiments, the detection mechanism includes a plurality of induction switches, and the plurality of induction switches are arranged at intervals along the length direction of the limit seat 21. Exemplarily, the induction switch can be, but is not limited to, an infrared induction switch, a microwave induction switch, an ultrasonic induction switch, a piezoelectric induction switch, an electromagnetic induction switch or a capacitance induction switch.

[0077] Exemplarily, the plurality of induction switches can be arranged at intervals on the movable floor 22 along the telescopic direction of the movable floor 22. It can be judged whether the safety boots 10 have accidentally moved or the placement position is significantly abnormal according to the number of triggered induction switches.

[0078] Exemplarily, the safety boots 10 are placed at the initial position. At the initial position, record the number of induction switches that the safety boots 10 can trigger as M, where M ≥ 1 and M ≤ the number of induction switches; at this time, if all the induction switches are not triggered, an alarm reminder "The position of the safety boots is abnormal, please check" is given.

[0079] Subsequently, continuously detect the number of detection switches triggered by the safety boots 10. For example, the following judgment rule can be adopted: If the number of induction switches triggered by the safety boots 10 is not equal to M, trigger an alarm reminder, such as a voice reminder: "The safety boots have abnormal displacement, please check."

[0080] Of course, other judgment rules can also be adopted. Taking the number of induction switches as five as an example, the five induction switches are represented by S1, S2, S3, S4, and S5 respectively. The distance between adjacent induction switches is a set value. At the initial position, S1 and S2 are triggered. If it is detected that S4 and S5 are triggered, an alarm reminder will also be triggered. Different judgment rules are related to factors such as the number of induction switches and the size of the spacing, which will not be described in detail here.

[0081] It should be understood that on the basis of the same structure of the detection mechanism, other judgment rules can also be adopted.

[0082] In addition, a certain judgment rule is set at the time of factory shipment, and the judgment rule can also be changed in actual application to further improve the accuracy of the alarm.

[0083] This embodiment also provides a boarding bridge, including the receiving port provided in this embodiment.

[0084] For the boarding bridge provided in this embodiment, since the receiving port provided in this embodiment is used, when docking with the aircraft, the second end of the limiting member 131 can be first driven to move relative to the holding handle 12 so that the first end of the limiting member 131 is in the second working position. Then, the safety boot 10 is placed at the corresponding position of the receiving port so that the first end of the limiting member 131 is aligned with the limiting portion. Then, the second end of the limiting member 131 is further driven to move relative to the holding handle 12 so that the first end of the limiting member 131 is in the first working position. At this time, the first end of the limiting member 131 cooperates with the limiting portion, thereby installing the safety boot 10 on the limiting seat 21, reducing the possibility of the position of the safety boot 10 shifting, and further reducing the risk of damage to the aircraft cabin door.
