Description

Technical Field

[0001] This utility model relates to the field of boarding bridges, and in particular to a safety warning device for the boarding bridge access port. Background Technology

[0002] Currently, commonly used safety guardrail warning devices on the side of the boarding bridge access floor consist of small warning signs and hinged mechanisms that can move left and right. Because the warning signs are small, they cannot effectively prevent staff and passengers from accidentally entering the left side of the access floor. Since there are gaps and important actuators (safety boots) on the left side of the access floor, it is easy for people to fall through the gaps or accidentally touch the actuators, leading to personal injury and equipment accidents. To prevent staff and passengers from accidentally entering the left side of the access floor and to improve the safety performance of the boarding bridge during use, a new boarding bridge access safety warning device is needed to solve these problems. Utility Model Content

[0003] The purpose of this utility model is to provide a safety warning device for boarding bridge gates, which solves the problem that current warning barriers are not convenient for blocking and reminding staff and passengers of safety.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A boarding bridge gate safety warning device includes:

[0006] A guardrail assembly, comprising a guardrail base, a guardrail body fitted onto one side of the guardrail base, and a movable guardrail end fitted onto one side of the guardrail body. The guardrail body is configured with multiple sleeves interlocked, and the guardrail base and the movable guardrail end are respectively fitted onto both ends of the guardrail body.

[0007] A compressed air tank, the output end of which is connected to an air intake pipe, one end of which is connected to one side of the guardrail base.

[0008] Furthermore, the guardrail assembly is configured as a flexible structure.

[0009] Furthermore, the overall size of the guardrail assembly decreases from left to right.

[0010] Furthermore, a pipe interface is provided on one side of the guardrail base at the location of the air intake pipe, and the air intake pipe is connected to the guardrail assembly through the pipe interface.

[0011] Furthermore, a pull strap is fixed between the guardrail base and the inside of the guardrail movable end.

[0012] Furthermore, a pulley is installed on one side of the inner wall of the guardrail base, and a portion of the pull strap is fitted onto the outer surface of the pulley.

[0013] Furthermore, the number of pulleys is set to two, with one pulley above the other, and the number of pull straps is also set to two, with each pull strap being sleeved on one of the two pulleys.

[0014] Furthermore, the pull belt is configured as an elastic structure, and the pulley is configured as a spring-loaded return pulley.

[0015] Furthermore, an air intake solenoid valve is installed on the air intake pipe.

[0016] Furthermore, it also includes a boarding bridge body, one end of which is equipped with a boarding gate, and a boarding floor is installed at the bottom of the boarding gate. The guardrail base of the guardrail assembly is installed on one side of the boarding gate, and the air pipe solenoid valve is installed at the bottom of the boarding floor.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Through the guardrail assembly, in conjunction with a compressed air tank and air intake pipe, compressed air from the compressed air tank is introduced into the guardrail assembly through the pipe joint. The guardrail body is propelled by the injected air, causing it to move and the movable end of the guardrail to slowly extend until the entire guardrail body is extended. Safety warning signs are printed on the side of the guardrail body at this point, making the warning signs fully visible. This achieves flexible safety warning isolation, and the extended guardrail assembly can block staff and passengers from accidentally entering the left side of the boarding floor, ultimately achieving the goal of airport operational safety.

[0019] 2. By using the pulleys on the guardrail base, in conjunction with the strap between the guardrail base and the movable end of the guardrail, when the compressed air tank stops inflating the inside of the guardrail assembly, that is, when the guardrail assembly is not under continuous thrust, the stretched strap retracts due to the elastic force, thereby driving the movable end of the guardrail to close into the inside of the guardrail body. Furthermore, the pulley rotates and pulls the strap, so that the movable end of the guardrail and the guardrail body are completely closed. Attached Figure Description

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] This utility model embodiment provides a safety warning device for boarding bridge gates. Please refer to [link / reference]. Figures 1-3 The system includes: a guardrail assembly and a compressed air tank 9. The guardrail assembly includes a guardrail base 4, a guardrail body 5 fitted onto one side of the guardrail base 4, and a guardrail movable end 6 fitted onto one side of the guardrail body 5. The guardrail body 5 is configured with multiple sleeves fitted onto each other. The guardrail base 4 and the guardrail movable end 6 are respectively fitted onto both ends of the guardrail body 5. The output end of the compressed air tank 9 is connected to an air intake pipe 10, and one end of the air intake pipe 10 is connected to one side of the guardrail base 4.

[0031] like Figures 1-3 As shown, the guardrail base 4 serves as the basic support for the guardrail assembly, providing a stable installation foundation for the entire guardrail assembly. This ensures that the guardrail assembly can be securely installed at the relevant location of the boarding bridge gate, bearing the weight of the guardrail body 5 and the movable end 6, as well as any external forces that may be applied, thus guaranteeing the stability of the overall guardrail structure.

[0032] The guardrail body 5 (with multiple sleeves interlocked) has a structure that makes it retractable. When needed, the guardrail body 5 can be stretched out according to the actual space requirements to effectively isolate, protect, and warn. When not in use or needing to be stored, the guardrail body 5 can be easily compressed to save space. At the same time, the interlocking of multiple sleeves also increases the structural strength of the guardrail body 5, making it better able to withstand external impacts.

[0033] The movable end 6 of the guardrail can move along with the extension and retraction of the guardrail body 5, further enhancing the overall flexibility and adjustability of the guardrail.

[0034] Compressed air tank 9 serves as an air source supply device, providing power to the entire safety warning device. By storing compressed air, it can release the compressed air when needed to provide power support for specific actions of the guardrail components (such as extension and retraction). It is one of the key components for the entire device to achieve automation. The air inlet pipe 10 connects the compressed air tank 9 and the guardrail base 4, guiding the compressed air output from the compressed air tank 9 to one side of the guardrail base 4 to deliver the power medium to the guardrail components, ensuring that the compressed air can be accurately transmitted to the required position to drive the guardrail components to perform corresponding actions.

[0035] Specific operating process: The guardrail assembly is initially in a retracted state, with multiple sleeves of the guardrail body 5 overlapping each other, and the movable end 6 of the guardrail close to the guardrail base 4. At this time, the entire guardrail assembly occupies relatively little space. When the boarding bridge is ready to connect with the aircraft door and a safety warning device is required, the control system issues a command to open the relevant valves on the air intake pipe 10 (such as the air pipe solenoid valve 11). Compressed air in the compressed air tank 9 enters one side of the guardrail base 4 through the air intake pipe 10. The compressed air entering the guardrail base 4 exerts a force on the guardrail body 5. Since the guardrail body 5 is a structure of multiple sleeves overlapping each other, under the action of compressed air, the sleeves extend outward in sequence, and the movable end 6 of the guardrail moves outward with the extension of the guardrail body 5 until the guardrail assembly extends to the predetermined length and shape, forming an effective isolation and protective barrier to prevent personnel from accidentally falling or other accidents in the boarding bridge docking area.

[0036] Please continue reading. Figures 1-3 The guardrail assembly is designed as a flexible structure. The overall size of the guardrail assembly decreases from left to right. A pipe interface is provided on one side of the guardrail base 4 at the location of the air intake pipe 10. The air intake pipe 10 is connected to the guardrail assembly through the pipe interface.

[0037] like Figures 1-3 As shown, in the boarding bridge arrival area, when a person accidentally bumps into the guardrail assembly, the flexible structure can absorb the collision energy through its own deformation, reducing the impact on the person and preventing injury from the collision.

[0038] The overall size of the guardrail components decreases from left to right. This gradual structural design creates a visual guiding effect, allowing people to move more naturally along the direction of the guardrail components when approaching the boarding bridge gate, and preventing them from walking into dangerous areas due to confusion or misjudgment.

[0039] The pipe interface provides a fixed and precise position for the connection between the air intake pipe 10 and the guardrail assembly, ensuring that the air intake pipe 10 can be stably connected to the guardrail assembly and avoiding compressed air leakage or device malfunction due to unstable connection.

[0040] Please continue reading. Figures 1-3 A pull strap 8 is fixed between the guardrail base 4 and the guardrail movable end 6. A pulley 7 is installed on one side of the inner wall of the guardrail base 4. Part of the pull strap 8 is sleeved on the outer surface of the pulley 7. The number of pulleys 7 is set to two, with one pulley 7 on top of the other. The number of pull straps 8 is also set to two, with the two pull straps 8 respectively sleeved on the two pulleys 7. The pull strap 8 is set to an elastic structure, and the pulley 7 is set to a spring return pulley 7.

[0041] like Figures 1-3As shown, the pull strap 8 plays a physical limiting role during the extension of the guardrail assembly, preventing the distance between the guardrail movable end 6 and the guardrail base 4 from becoming too large, avoiding damage or loss of stability to the guardrail body 5 due to overextension, and ensuring that the guardrail assembly can extend and retract within a safe range. When the guardrail assembly needs to be retracted, the pull strap 8 can provide a pulling force to help the guardrail movable end 6 move towards the guardrail base 4, so that the guardrail body 5 can be smoothly retracted, accelerating the retraction speed of the guardrail assembly and improving the working efficiency of the device.

[0042] The design of pulley 7 allows the pull belt 8 to slide more smoothly during movement, reducing the friction between the pull belt 8 and the inner wall of the guardrail base 4, reducing energy loss, improving the working efficiency of the pull belt 8, and also reducing wear on the pull belt 8, extending its service life. Pulley 7 can change the direction of the pulling force of the pull belt 8, allowing the pull belt 8 to more effectively transmit the force to the movable end 6 of the guardrail, realizing the stable extension and contraction of the guardrail component. By reasonably setting the position and direction of pulley 7, the effect of the pulling force can be optimized, and the overall performance of the device can be improved.

[0043] The arrangement of two pulleys 7 and two straps 8 can evenly distribute the tension on the upper and lower parts of the guardrail assembly, making the force on the movable end 6 of the guardrail more balanced during the extension and retraction process. This avoids the guardrail assembly from tilting or deforming due to excessive force on one side, and improves the stability of the device.

[0044] When the guardrail assembly is impacted by external force, the elastic pull strap 8 can absorb some energy through its own elastic deformation, playing a buffering role and reducing the damage to the guardrail assembly. At the same time, it can also reduce the reaction force on personnel and improve the safety of personnel collisions. The spring return pulley 7 works in conjunction with the elastic pull strap 8. After the guardrail assembly completes the extension or retraction action, the spring return pulley 7 can automatically rotate using the spring force to restore the guardrail assembly to its initial position. At the same time, the elastic pull strap 8 will also drive the movable end 6 of the guardrail to return to its original position, realizing the automatic return function of the guardrail assembly without manual intervention and improving the automation level of the device.

[0045] Please continue reading. Figures 1-3 An air intake solenoid valve 11 is installed on the air intake pipe 10.

[0046] like Figures 1-3 As shown, the air pipe solenoid valve 11 is installed on the air intake pipe 10. Its core function is to precisely control the opening and closing of the air passage between the compressed air tank 9 and the guardrail assembly. By receiving electrical signals from the control system, the solenoid valve can quickly open or close, thereby determining whether compressed air can enter the guardrail assembly through the air intake pipe 10.

[0047] Please see Figures 1-4It also includes a boarding bridge body 1, a boarding gate 2 installed at one end of the boarding bridge body 1, a boarding floor 3 installed at the bottom of the boarding gate 2, a guardrail base 4 of the guardrail assembly installed on one side of the boarding gate 2, and an air pipe solenoid valve 11 installed at the bottom of the boarding floor 3.

[0048] like Figures 1-4 As shown, the boarding bridge body 1 is the main load-bearing and connecting component of the entire device. It provides a passage for the boarding gate 2 to connect with the aircraft door, enabling passengers to travel safely and conveniently between the ground and the aircraft. At the same time, it also provides an installation base and a relatively stable working environment for other components such as the guardrail assembly and the air pipe solenoid valve 11.

[0049] Gate 2 is a crucial location for passengers to enter and exit the aircraft, and it is also the core area where the boarding bridge connects to the aircraft. It serves as an important reference point for the safety railing components, which are installed around Gate 2 to prevent passengers from accidentally falling during boarding or disembarking.

[0050] The boarding floor 3 provides a supporting surface for passengers to walk on the boarding bridge, ensuring the stability and comfort of passengers. At the same time, it is also a load-bearing structure for installing components such as the endotracheal solenoid valve 11, providing a relatively fixed and easy-to-wire installation position for the endotracheal solenoid valve 11.

[0051] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model 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 of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
