Description

Technical Field

[0001] This application relates to the field of airport ground equipment technology, and more particularly to an adjustment device for an airport jet bridge. Background Technology

[0002] Airport jet bridges (also known as boarding bridges or air bridges) are movable, enclosed passageways connecting terminal boarding gates to aircraft cabin doors. They are key facilities in modern airports, with their core function being to enhance passenger safety and comfort during boarding. Currently, airport jet bridges commonly use hydraulic or electric drive systems to achieve lifting and retraction functions to accommodate the different door heights and distances of various aircraft types. With the development of the aviation industry and the diversification of aircraft types, higher demands are placed on the precision and speed of jet bridge adjustments.

[0003] Currently, airport boarding bridge docking relies heavily on manual observation or simple sensor feedback, which is insufficient to meet the needs of rapid and accurate docking under complex weather conditions. Therefore, an improvement has been made to an adjustment device for airport boarding bridges. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides an adjustment device for airport boarding bridges, which overcomes the shortcomings of the prior art and aims to solve the problem that the current docking of airport boarding bridges mostly relies on manual observation or simple sensor feedback, which is difficult to meet the needs of rapid and accurate docking under complex weather conditions.

[0005] To achieve the above objectives, this application provides the following technical solution: an adjustment device for an airport boarding bridge, comprising a fixed boarding bridge, the fixed boarding bridge being fixedly installed at the terminal interface, a telescopic boarding bridge being slidably inserted inside the fixed boarding bridge, a walking support mechanism being fixedly installed on one side of the lower surface of the telescopic boarding bridge, an aircraft receiving cabin being rotatably connected inside the port of the telescopic boarding bridge, a mounting frame being fixedly connected to the lower surface of the telescopic boarding bridge, a rotating unit for driving the aircraft receiving cabin to rotate being provided inside the mounting frame, a pressure sensor and an infrared rangefinder being fixedly installed on the lower surface of the aircraft receiving cabin, a docking unit being provided in front of the pressure sensor, the docking unit comprising a positioning block fixedly installed at the bottom of the aircraft receiving cabin, a positioning hole being provided through the positioning block, a sliding rod being slidably inserted inside the positioning hole, a docking block being fixedly connected to the front end of the sliding rod, a pressing block being fixedly connected to the rear end of the sliding rod, a spring being sleeved on the outer wall of the sliding rod, and the pressing block being fixedly connected to the positioning block through the spring.

[0006] By adopting the above technical solution, the receiving cabin is rotated by the rotating unit to align with the aircraft cabin door. The telescopic bridge moves towards the fuselage under the drive of the walking support mechanism. During the docking process, the docking block contacts the fuselage first and drives the sliding rod and the pressing block to move backward. When the pressing block triggers the pressure sensor, the telescopic bridge immediately stops moving to complete the docking work. The contact pressure between the receiving cabin and the fuselage is monitored in real time through the cooperation between the pressure sensor and the docking unit. The infrared rangefinder accurately measures the docking distance, replacing manual observation and improving data reliability. The two work together to feed back to the control system, which significantly improves docking efficiency and safety. It is especially suitable for low visibility scenarios such as rain, snow, and fog.

[0007] As a preferred technical solution of this application, the number of infrared rangefinders is set to two, and the two infrared rangefinders are symmetrically distributed on both sides of the docking unit.

[0008] By adopting the above technical solution, two infrared rangefinders are symmetrically arranged to form a differential measurement system. By comparing the distance data between the two infrared rangefinders and the fuselage in real time, the horizontal deflection angle and parallelism deviation of the docking cabin relative to the aircraft cabin door can be accurately calculated.

[0009] As a preferred technical solution of this application, the rotating unit includes a motor fixedly installed inside the mounting frame. The output end of the motor is fixedly connected to a drive drive wheel. A driven drive wheel is arranged parallel to one side of the drive drive wheel.

[0010] By adopting the above technical solution, the motor drives the active transmission wheel to rotate, and the power is transmitted to the receiving cabin through the cooperation between the driven transmission wheel, the active transmission wheel and the transmission belt, so that the receiving cabin can rotate under the driving action of the rotating unit.

[0011] As a preferred technical solution of this application, the number of the positioning hole, the sliding rod and the spring are all two and correspond one-to-one, and the diameter of the sliding rod is adapted to the inner diameter of the positioning hole.

[0012] By adopting the above technical solution, the movement trajectory of the docking block is limited by the cooperation between the positioning hole and the sliding rod, so as to avoid the docking block from deviating during movement and ensure the accuracy of the docking block's movement.

[0013] As a preferred technical solution of this application, the positioning block, sliding rod, docking block and extrusion block are all stainless steel components, and a rubber pad is fixedly bonded to the front side of the docking block.

[0014] By adopting the above technical solution, the components made of stainless steel are not easily damaged, have a long service life, and the rubber pads play a cushioning role.

[0015] As a preferred technical solution of this application, the side wall of the receiving cabin and the port of the retractable corridor are fixedly connected with louvered folding railings.

[0016] By adopting the above technical solution, when the receiving cabin rotates, the louvered folding fence can automatically adjust the folding angle according to the rotation angle, effectively filling the gap between the receiving cabin and the retractable bridge, and completely preventing rain, snow and strong wind from entering the interior of the bridge passage through the interface gap.

[0017] As a preferred technical solution of this application, a hydraulic cylinder is fixedly installed on the side wall of the walking support mechanism, and an anti-slip pad is fixedly connected to the telescopic end of the hydraulic cylinder.

[0018] By adopting the above technical solution, the anti-slip pad is driven by a hydraulic cylinder to move downwards and contact the ground, thereby fixing the retractable bridge.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In this invention, the receiving cabin is driven to rotate by a rotating unit so that it aligns with the aircraft cabin door. The telescopic walkway moves toward the fuselage under the drive of the walking support mechanism. During the docking process, the docking block contacts the fuselage first and drives the sliding rod and the pressing block to move backward. When the pressing block triggers the pressure sensor, the telescopic walkway immediately stops moving to complete the docking work. The contact pressure between the receiving cabin and the fuselage is monitored in real time through the cooperation between the pressure sensor and the docking unit. The infrared rangefinder accurately measures the docking distance, replacing manual observation and improving data reliability. The two work together to feed back to the control system, which significantly improves docking efficiency and safety. It is especially suitable for low visibility scenarios such as rain, snow, and fog.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] like Figure 1 - Figure 4 As shown, this embodiment provides an adjustment device for an airport boarding bridge, including a fixed boarding bridge 1, which is fixedly installed at the terminal interface. A telescopic boarding bridge 2 is slidably inserted inside the fixed boarding bridge 1. A walking support mechanism 3 is fixedly installed on one side of the lower surface of the telescopic boarding bridge 2. An aircraft receiving cabin 4 is rotatably connected inside the port of the telescopic boarding bridge 2. A mounting frame 5 is fixedly connected to the lower surface of the telescopic boarding bridge 2. A rotating unit 6 for driving the aircraft receiving cabin 4 to rotate is provided inside the mounting frame 5. A pressure sensor 8 and an infrared rangefinder 9 are fixedly installed on the lower surface of the aircraft receiving cabin 4. A docking unit 7 is provided in front of the pressure sensor 8. The docking unit 7 includes a positioning block 71 fixedly installed at the bottom of the aircraft receiving cabin 4. A positioning hole 72 is opened through the interior of the positioning block 71. A sliding rod 73 is slidably inserted inside the positioning hole 72. A docking block 74 is fixedly connected to the front end of the sliding rod 73, and a pressing block 75 is fixedly connected to the rear end of the sliding rod 73. A spring 76 is sleeved on the outer wall of the sliding rod 73, and the pressing block 75 is fixedly connected to the positioning block 71 through the spring 76. In use, the receiving cabin 4 is driven to rotate by the rotating unit 6 so that it is aligned with the aircraft cabin door. The telescopic bridge 2 moves towards the fuselage under the drive of the walking support mechanism 3. During the docking process, the docking block 74 contacts the fuselage first and drives the sliding rod 73 and the pressing block 75 to move backward. When the pressing block 75 triggers the pressure sensor 8, the telescopic bridge 2 immediately stops moving to complete the docking work. The contact pressure between the receiving cabin 4 and the fuselage is monitored in real time through the cooperation between the pressure sensor 8 and the docking unit 7. The infrared rangefinder 9 accurately measures the docking distance, replacing manual observation.

[0030] In this embodiment, as Figure 1As shown, there are two infrared rangefinders 9, which are symmetrically distributed on both sides of the docking unit 7. In use, the two infrared rangefinders 9 are arranged symmetrically to form a differential measurement system. By comparing the distance data between the two infrared rangefinders 9 and the fuselage in real time, the horizontal deflection angle and parallelism deviation of the docking cabin 4 relative to the aircraft cabin door can be accurately calculated.

[0031] In this embodiment, as Figure 1 and 3 As shown, the rotating unit 6 includes a motor 61 fixedly installed inside the mounting frame 5. The output end of the motor 61 is fixedly connected to a drive drive wheel 62. A driven drive wheel 63 is arranged parallel to one side of the drive drive wheel 62. The driven drive wheel 63 is fixedly connected to the lower end of the receiving compartment 4. A transmission belt 64 is provided between the driven drive wheel 63 and the drive drive wheel 62. In use, the motor 61 drives the drive drive wheel 62 to rotate, and the power is transmitted to the receiving compartment 4 by the cooperation between the driven drive wheel 63, the drive drive wheel 62 and the transmission belt 64, so that the receiving compartment 4 can rotate under the driving action of the rotating unit 6.

[0032] In this embodiment, as Figure 4 As shown, there are two of each of the positioning hole 72, sliding rod 73 and spring 76, and they correspond one-to-one. The diameter of the sliding rod 73 is matched with the inner diameter of the positioning hole 72. In use, the movement trajectory of the docking block 74 is limited by the cooperation between the positioning hole 72 and the sliding rod 73, so as to prevent the docking block 74 from deviating during movement and ensure the accuracy of the movement of the docking block 74.

[0033] In this embodiment, as Figure 4 As shown, the positioning block 71, sliding rod 73, docking block 74 and pressing block 75 are all stainless steel components. A rubber pad 77 is fixedly bonded to the front side of the docking block 74. During use, the components made of stainless steel are not easily damaged and have a long service life. The rubber pad 77 plays a buffering role.

[0034] In this embodiment, as Figure 2 As shown, a louvered folding fence 10 is fixedly connected to the side wall of the receiving cabin 4 and the port of the telescopic corridor 2. When the receiving cabin 4 is rotated, the louvered folding fence 10 can automatically adjust the folding angle according to the rotation angle, effectively filling the gap between the receiving cabin 4 and the telescopic corridor 2, and completely preventing rain, snow and strong wind from entering the corridor passage from the interface gap.

[0035] In this embodiment, as Figure 2 As shown, a hydraulic cylinder 11 is fixedly installed on the side wall of the walking support mechanism 3. An anti-slip pad 12 is fixedly connected to the telescopic end of the hydraulic cylinder 11. In use, the anti-slip pad 12 is driven to move downward and abut against the ground by the hydraulic cylinder 11, thereby fixing the telescopic bridge 2.

[0036] The working principle of this utility model is as follows: When using the airport boarding bridge adjustment device of this application, the telescopic boarding bridge 2 moves towards the fuselage under the drive of the walking support mechanism 3. The motor 61 drives the active transmission wheel 62 to rotate, and the power is transmitted to the receiving cabin 4 through the cooperation between the driven transmission wheel 63, the active transmission wheel 62 and the transmission belt 64. The receiving cabin 4 is driven to rotate so that it is aligned with the aircraft cabin door. During the alignment process, the distance data between the receiving cabin 4 and the fuselage is detected by two infrared rangefinders 9. The horizontal deflection angle and parallelism deviation of the receiving cabin 4 relative to the aircraft cabin door can be accurately calculated. Then, the telescopic boarding bridge 2 continues to move to perform docking work. The docking block 74 first contacts the fuselage and drives the sliding rod 73 and the pressing block 75 to move backward. When the pressing block 75 triggers the pressure sensor 8, the walking support mechanism 3 immediately stops moving. Then, the hydraulic cylinder 11 is activated so that the anti-slip pad 12 moves downward to abut against the ground, thereby fixing the telescopic boarding bridge 2 and completing the docking work.
