[0081] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this application will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0082] It is understood that the terms "comprising" and "having," and any variations thereof, in the embodiments of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to these processes, methods, products, or devices.

[0083] Unless otherwise specified, in the claims and description, the terms “center,” “lateral,” “longitudinal,” “horizontal,” “vertical,” “top,” “bottom,” “inner,” “outer,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “clockwise,” “counterclockwise,” etc., indicate the orientation or positional relationship based on the orientation and positional relationship shown in the drawings, and are only for the purpose of simplifying the description, and do not imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation.

[0084] like Figure 1 As shown, the boarding bridge in this embodiment includes a walking mechanism 10 and a bridge removal device 20. The bridge removal device 20 can be installed on the walking mechanism 10 to drive the walking mechanism 10 to move, so as to realize rapid bridge removal in an emergency.

[0085] The bridge removal device 20 can be detachably connected to the traveling mechanism 10. When an emergency occurs and the bridge needs to be removed, the bridge removal device 20 is installed on the traveling mechanism 10. When no emergency occurs, the bridge removal device 20 is removed from the traveling mechanism 10.

[0086] Of course, in other embodiments, the bridge removal device 20 may always be installed on the walking mechanism 10 without affecting its normal movement. When an emergency occurs requiring bridge removal, the bridge removal device 20 is connected to the walking wheel 13 of the walking mechanism 10 via a transmission connection; when no emergency occurs, the bridge removal device 20 is only installed on the walking mechanism 10, but is not connected to the walking wheel 13 via a transmission connection.

[0087] The term "transmission connection" refers to a connection between two components in which the motion and power generated by one component can be transmitted to the other component, causing the other component to move accordingly.

[0088] For example, when the bridge removal device 20 is connected to the traveling wheel 13 of the traveling mechanism 10, the motion generated by the bridge removal device 20 can be transmitted to the traveling wheel 13 so that the traveling wheel 13 rotates.

[0089] like Figure 1 and Figure 2 As shown, the walking mechanism 10 includes a wheel frame 11, a walking motor 12, and walking wheels 13. Walking wheels 13 are respectively provided at both ends of the wheel frame 11. The walking motor 12 is mounted on the wheel frame 11 and is connected to the walking wheels 13 in a transmission manner. The walking motor 12 can drive the walking wheels 13 to rotate.

[0090] In an exemplary embodiment, the wheel frame 11 is provided with a receiving cavity 112, and the walking motor 12 is disposed in the receiving cavity 112.

[0091] In one embodiment, the wheel frame 11 includes two opposing crossbeams 111, which together form a receiving cavity 112.

[0092] Of course, in other embodiments, the walking mechanism 10 may also adopt other structures.

[0093] like Figure 1 and Figure 3 As shown, the bridge removal device 20 includes a drive assembly 21 and a connecting assembly 22. The connecting assembly 22 includes an active member 221 and a passive member 222. The active member 221 and the passive member 222 are connected in a driving manner, and the drive assembly 21 is connected in a driving manner to the active member 221. When the bridge removal device 20 is installed on the walking mechanism 10, the drive assembly 21 can be installed on the wheel frame 11 and / or the walking motor 12, and at least a portion of the passive member 222 can extend into the receiving cavity 112 to be connected in a driving manner to the walking motor 12.

[0094] The bridge removal device 20 of this embodiment includes a connecting component 22 comprising a driving member 221 and a driven member 222 connected by a transmission connection. Since the driving member 221 is connected to the drive component 21, the movement and power of the drive component 21 can be transmitted to the driven member 222 via the driving member 221. When the bridge removal device 20 is installed on the traveling mechanism 10, the drive component 21 can be installed on the wheel frame 11 and / or the traveling motor 12, and the driven member 222 can extend into the receiving cavity 112 to be connected to the traveling motor 12 by a transmission connection. Thus, for the traveling mechanism 10 where the traveling motor 12 is located within the receiving cavity 112 of the wheel frame 11, the bridge removal device 20 of this embodiment can also establish a transmission connection with the traveling motor 12, enabling emergency bridge removal in case of emergencies. Therefore, the bridge removal device 20 of this embodiment can be adapted to various types of traveling mechanisms 10, thus having a wider range of applications.

[0095] It is understandable that when the drive assembly 21 is connected to the wheel frame 11, the drive assembly 21 can be connected to one of the crossbeams 111, or to both crossbeams 111 at the same time, or to other parts of the wheel frame 11.

[0096] In one embodiment, the drive component 21 includes a motor.

[0097] In one embodiment, the drive assembly 21 and the wheel frame 11 of the walking mechanism 10 are respectively provided with limiting structures for cooperating to limit the drive assembly 21. Through the cooperation of the limiting structures of the drive assembly 21 and the wheel frame 11, the drive assembly 21 can be stably mounted on the wheel frame 11, ensuring that the power of the drive assembly 21 is stably transmitted to the walking motor 12.

[0098] In one embodiment, the limiting structure of the drive assembly 21 engages with the limiting structure of the wheel frame 11. By designing the limiting structure of the drive assembly 21 and the limiting structure of the wheel frame 11 to engage, the drive assembly 21 can be quickly installed on the wheel frame 11, thereby promptly establishing a transmission connection between the driven component 222 of the connecting assembly 22 and the walking motor 12, achieving the effect of rapid bridge removal and avoiding serious consequences caused by untimely bridge removal.

[0099] like Figures 4 to 6 As shown, the limiting structure of the drive assembly 21 is provided with a latch 30, and the limiting structure of the wheel frame 11 is provided with a mating part 14. The latch 30 is used to engage with the mating part 14. The bridge removal device 20 can be arranged on the crossbeam 111 and move relative to the wheel frame 11 along the length direction of the crossbeam 111. During the movement, when the latch 30 engages with the mating part 14, the passive component 222 is connected to the travel motor 12.

[0100] When assembling the bridge removal device 20 with the traveling mechanism 10, the drive assembly 21 can be first arranged on the crossbeam 111, and one end of the connecting assembly 22 with the passive member 222 extends into the receiving cavity 112. Then, it moves along the length of the crossbeam 111 towards the mating part 14. When the latch 30 engages with the mating part 14, the passive member 222 also connects to the traveling motor 12. Therefore, in this embodiment, the latch 30 of the drive assembly 21 engages with the mating part 14, and the passive member 222 connects to the traveling motor 12 simultaneously, facilitating the operator's operation.

[0101] Furthermore, such as Figure 5 and Figure 6 As shown, the latch 30 includes a lock body 31, a latch 32, and an operating member 33. The latch 32 is telescopically connected to the lock body 31, and the operating member 33 is linked to the latch 32. When the operating member 33 is operated by an external force, the latch 32 retracts into the lock body 31, and when the operating member 33 is not operated by an external force, the latch 32 extends out of the lock body 31. The mating part 14 has a first side 142 and a second side 143 arranged opposite to each other along the length direction of the crossbeam 111.

[0102] like Figures 7 to 9 As shown, during the movement of the locking tongue 32 from the first side 142 to the second side 143 of the mating part 14, when the locking tongue 32 contacts the mating part 14, the locking tongue 32 can be squeezed by the mating part 14 and retract into the lock body 31. After the locking tongue 32 crosses the mating part 14, the locking tongue 32 extends out from the lock body 31 and is locked on the second side 143 of the mating part 14. When the locking tongue 32 is locked on the second side 143 of the mating part 14, the driven member 222 is connected to the walking motor 12.

[0103] At this time, the locking tongue 32 is engaged on the second side 143 of the mating part 14, and the locking tongue 32 will not retract into the lock body 31 without the operation member 33 being operated. Therefore, the locking tongue 32 cannot move from the second side 143 to the first side 142 of the mating part 14. In addition, when the locking tongue 32 is engaged on the second side 143 of the mating part 14, the drive assembly 21 is close to the end of the wheel frame 11, so the bridge removal device 20 is limited on the wheel frame 11 in the length direction of the crossbeam 111.

[0104] like Figure 5 and Figure 6 As shown, the limiting structure of the drive assembly 21 is also provided with a limiting part 211, and the mating part 14 is provided on one of the crossbeams 111. The mating part 14 is provided with a limiting groove 141 with an opening facing the other crossbeam 111. When the locking tongue 32 is located on the second side 143 of the mating part 14, the limiting part 211 is inserted into the limiting groove 141.

[0105] In this embodiment, the relative displacement between the drive assembly 21 and the crossbeam 111 can be restricted in the vertical direction by the cooperation of the limiting part 211 and the limiting groove 141.

[0106] like Figure 10 and Figure 11 As shown, the connecting assembly 22 also includes a housing 224 and a transmission component 223. The active component 221 is connected to the passive component 222 via the transmission component 223. The housing 224 is a hollow shell structure, and the active component 221, the transmission component 223 and the passive component 222 are disposed inside the housing 224.

[0107] In one embodiment, the driving member 221, the transmission member 223, and the driven member 222 constitute a sprocket and chain transmission mechanism, that is, the driving member 221 is the driving sprocket, the driven member 222 is the driven sprocket, and the transmission member 223 is the chain, which is wound around the outer periphery of the driving sprocket and the driven sprocket.

[0108] In another embodiment, the driving member 221, the transmission member 223, and the driven member 222 can also constitute a synchronous belt transmission mechanism, that is, the driving member 221 is the main synchronous pulley, the driven member 222 is the driven synchronous pulley, and the transmission member 223 is the synchronous belt, which is wrapped around the outer periphery of the main synchronous pulley and the driven synchronous pulley.

[0109] In another embodiment, the driving member 221, the transmission member 223, and the driven member 222 can also constitute a gear transmission mechanism.

[0110] like Figures 12 to 14 As shown, the driven member 222 has a through hole 2222 through which the tail shaft 121 of the walking motor 12 passes. The wall of the through hole 2222 has a receiving groove 2221, and a rotatable claw 23 is provided in the receiving groove 2221. One end of the claw 23 is rotatably connected to the driven member 222, and the other end is a free end. The claw 23 can rotate between a position extending out of the receiving groove 2221 and a position received in the receiving groove 2221. The connecting assembly 22 also includes an elastic member 24, which is configured to apply an elastic force to the claw 23 to extend out of the receiving groove 2221. That is, when the claw 23 is not subjected to external force, the claw 23 extends out of the receiving groove 2221.

[0111] The outer periphery of the tail shaft 121 is provided with a groove 122, and the free end of the pawl 23 can be inserted into the groove 122.

[0112] When the driven member 222 moves toward the tail shaft 121, causing the tail shaft 121 to insert into the through hole 2222 of the driven member 222, if the pawl 23 is not aligned with the groove 122, the outer circumferential side of the tail shaft 121 can press against the pawl 23, causing the pawl 23 to overcome the elastic force of the elastic member 24 and rotate toward the position to be received in the receiving groove 2221. At this time, the drive assembly 21 starts to work and drives the driven member 222 to rotate. The driven member 222 drives the pawl 23 to rotate circumferentially along the tail shaft 121. When the position of the pawl 23 is aligned with the groove 122, under the action of the elastic force of the elastic member 24, the pawl 23 is engaged in the groove 122. At this time, the driven member 222 can drive the walking motor 12 to rotate together, thereby driving the walking wheel 13 to rotate.

[0113] If the tail shaft 121 is inserted into the through hole 2222 of the driven member 222, and the pawl 23 is aligned with the groove 122, then the pawl 23 will directly engage with the groove 122 of the tail shaft 121.

[0114] Therefore, by using the cooperation between the chuck 23 and the groove 122, when docking the driven part 222 and the tail shaft 121, there is no need to consider whether the chuck 23 is aligned with the groove 122, making it more convenient for operators to assemble.

[0115] In one embodiment, the elastic element 24 can be a leaf spring or a torsion spring.

[0116] like Figure 10 and Figure 15 As shown, a support portion 113 is fixedly provided inside the receiving cavity 112, and the connecting component 22 is provided with an overlapping portion 226, which is used to overlap the support portion 113.

[0117] In this embodiment, when one end of the connecting component 22 with the passive member 222 extends into the receiving cavity 112, the overlapping part 226 can overlap the support part 113 to further improve the stability of the connecting component 22.

[0118] like Figure 16 and Figure 17 As shown, the connecting component 22 is rotatable relative to the driving component 21 between a first position P1 and a second position P2. When the connecting component 22 is in the first position P1, its length direction L1 is parallel to the length direction L2 of the driving component 21; when the connecting component 22 is in the second position P2, its length direction L1 is angled to the length direction L2 of the driving component 21. The bridge removal device 20 also includes a locking component 225 for locking the connecting component 22 in either the first position P1 or the second position P2.

[0119] In an exemplary embodiment, when the locking component 225 locks the connecting component 22 in the second position P2, one end of the connecting component 22 with the passive member 222 can extend into the receiving cavity 112 so that the passive member 222 is connected to the walking motor 12 in a transmission manner.

[0120] In this embodiment, when the connecting component 22 is located at the first position P1, the bridge removal device 20 is in a non-working state. Since the length direction L1 of the connecting component 22 is parallel to the length direction L2 of the driving component 21, the bridge removal device 20 is generally elongated, which does not occupy too much space and is more conducive to storage and transportation.

[0121] like Figures 16 to 18 As shown, the locking component 225 includes a positioning pin 2251, which is disposed on the connecting component 22. The driving component 21 includes a fixing member 212, which has a first insertion hole 2121 and a second insertion hole 2122. When the connecting component 22 is in the first position P1, the positioning pin 2251 is inserted into the first insertion hole 2121. When the connecting component 22 is in the second position P2, the positioning pin 2251 is inserted into the second insertion hole 2122.

[0122] The positioning pin 2251 is inserted into the first socket 2121, and the connecting component 22 is locked in the first position P1. The positioning pin 2251 is pulled out and the connecting component 22 is rotated clockwise. When the positioning pin 2251 is inserted into the second socket 2122, the connecting component 22 is locked in the second position P2.

[0123] like Figure 18 As shown, the drive assembly 21 is also provided with a handle 213, which can be connected to the fixing member 212. In this embodiment, the drive assembly 21 is also provided with a handle 213 to facilitate the operator to pick up the bridge removal device 20.

[0124] like Figure 19 As shown, the bridge removal device 20 also includes a control component 40, which is electrically connected to the drive component 21 and is used to control the operation of the drive component 21. For example, when the drive component 21 includes a motor, the control component 40 is electrically connected to the motor and is used to control the motor to rotate forward or backward, thereby driving the walking mechanism 10 to move forward or backward.

[0125] Of course, the bridge removal device 20 in this embodiment can also drive the walking mechanism 10 to rotate. Specifically, the walking mechanism 10 includes two walking motors 12, which are respectively connected to two walking wheels 13. When the bridge removal device 20 is connected to one of the walking motors 12, the bridge removal device 20 can drive the walking wheel 13 corresponding to that walking motor 12 to rotate, thereby realizing the rotation of the walking mechanism 10.

[0126] The control assembly 40 includes a control box 41 and a power cord 42. One end of the power cord 42 is electrically connected to the drive assembly 21, and the other end is electrically connected to the control box 41. The control box 41 is equipped with control buttons.

[0127] In summary, the advantages and beneficial effects of the bridge removal device 20 and the boarding bridge according to the embodiments of this application include at least the following:

[0128] The bridge removal device 20 of this embodiment includes a connecting component 22 comprising a driving member 221 and a driven member 222 connected by a transmission connection. Since the driving member 221 is connected to the drive component 21, the movement and power of the drive component 21 can be transmitted to the driven member 222 via the driving member 221.
