Description

Technical Field

[0001] The invention relates to the technical field of civil aviation ground service equipment, in particular to a safety boot early warning device for monitoring the subsidence of an aircraft passenger ladder. Background Art

[0002] In modern civil aviation ground services, passenger staircases, as crucial aids for passengers boarding and disembarking, are widely used at airports without jetways. After docking, the aircraft experiences a certain degree of sinking due to operations such as boarding, refueling, and loading. This sinking can reach tens or even 20 centimeters, especially when heavily loaded or in inclement weather. If the staircase platform remains stationary during this period, the aircraft's cabin door could press down on the platform, preventing the staircase from leaving the aircraft in a timely manner. This could even lead to serious safety incidents such as equipment jamming or cabin door damage.

[0003] A common technical flaw currently exists: most passenger elevators lack automatic monitoring devices to detect subsidence, relying primarily on manual judgment of aircraft subsidence levels. This presents risks such as delayed response and misjudgment, particularly when visibility is obstructed or personnel are negligent. Therefore, there is an urgent need to design an early warning device that can interact with the aircraft door and automatically sense subsidence risks, thereby improving the intelligence and safety of airport boarding operations.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0035] Example

[0036] Reference Figures 1 to 8 This embodiment provides an aircraft passenger ladder settlement monitoring safety shoe warning device, which is used to monitor the settlement degree in real time and provide graded warnings when the aircraft settles due to boarding, refueling or bad weather after docking, so as to avoid the passenger ladder platform from getting stuck or the aircraft cabin door from being damaged.

[0037] The device comprises a base 100, a primary trigger mechanism 200, a secondary trigger mechanism 300, and associated connection and protection components. The base 100, serving as the device's main support structure, is made of high-strength metal (such as aluminum alloy) and is fixedly mounted to the passenger elevator docking platform to ensure overall structural stability and load-bearing capacity. Its rectangular or trapezoidal shape accommodates various passenger elevator platforms. The base 100 not only provides mechanical support but also facilitates secure connection to other components through pre-defined mounting holes and interfaces, enhancing the device's modular design and ease of installation.

[0038] The primary trigger mechanism 200, which provides primary detection and alarm for subsidence, is located on the left and right sides of the base 100 and comprises two touch panel hinges 201, a contact plate 202, two contact springs 203, and copper wire 204. The touch panel hinges 201 are made of high-toughness steel and fixed to the left and right sides of the base 100. Their sturdy structure and precise positioning ensure stable support and flexible movement of the contact plates 202. The contact plates 202 are hinged to the top of the touch panel hinges 201 via torsion springs. The torsion springs provide elastic rebound force, keeping the contact plates 202 separated from the contact springs 203 when unpressurized, preventing false triggering. Their elastic design also absorbs minor vibrations, extending the device's service life. The contact plates 202 are made of conductive metal (such as stainless steel) and located at the top of the touch panel hinges 201. As the component in direct contact with the aircraft door, their high strength and wear resistance ensure long-term reliability.

[0039] When the aircraft door is pressed down, the contact plate 202 moves downward to compress the contact spring 203, triggering the primary alarm. The two contact springs 203 are set at the front end of the touch plate hinge 201 and are located below the contact plate 202. They are made of highly conductive spring steel, with gold-plated contacts on the top to ensure low-resistance contact. Their bottom ends are electrically connected via copper wire 204. When compressed, the contact spring 203 closes the contact, forming a closed loop. The electrical signal is transmitted to the external alarm through the copper wire 204, triggering an audio prompt (such as a buzzer or voice warning) to alert staff to the slight risk of subsidence. The copper wire 204 uses a highly conductive copper core and is wrapped in a waterproof insulation layer. It connects the bottom ends of the two contact springs 203 and is electrically connected to the external alarm through an extension section. Its flexible design and corrosion resistance ensure the stability of signal transmission and environmental adaptability.

[0040] The secondary trigger mechanism 300, designed to provide further warning in the event of severe subsidence, is located between the two contact springs 203 and comprises a mounting frame 301, a rotating rod 302, a gear cylinder 303, a toggle lever 304, an arcuate tooth plate 305, a storage frame 306, a warning assembly 307, a positioning assembly 308, and a lifting assembly 309. The mounting frame 301, constructed of high-strength plastic or metal, is fixed to the interior of the base 100 and serves as the core support structure of the secondary trigger mechanism. The center of the mounting frame is rotatably connected to the gear cylinder 303 via the rotating rod 302. The rotating rod 302, constructed of stainless steel, extends through the mounting frame 301 and outward, where it is fixedly connected to the toggle lever 304. The low-friction design of the rotating rod 302 ensures smooth rotation of the gear cylinder 303 and toggle lever 304. Gear cylinder 303 is a cylindrical gear structure that meshes with an arcuate tooth plate 305 fixed to the lower surface of the top of contact plate 202. Arcuate tooth plate 305 is made of wear-resistant metal, and its arcuate design precisely matches gear cylinder 303, ensuring efficient force transmission when contact plate 202 is pressed downward. When contact plate 202 is excessively pressed downward due to severe subsidence, arcuate tooth plate 305 drives gear cylinder 303 to rotate forward. Gear cylinder 303, through rotating rod 302, drives toggle lever 304 forward and downward, creating a mechanical amplification effect and triggering the secondary warning mechanism. Toggle lever 304 acts as a force transmission component, and its lever design converts the slight rotation of rotating rod 302 into a significant mechanical action, enhancing trigger sensitivity.

[0041] Affixed to the front end of mounting bracket 301, storage frame 306 is made of corrosion-resistant metal or engineering plastic. It houses a storage cavity 306b, a retaining cavity 306a, and a telescoping cavity 306c for accommodating warning assembly 307. Storage cavity 306b stores warning sign 307a, while retaining cavity 306a restricts lateral movement. Telescoping cavity 306c provides space for positioning assembly 308. These three cavities work together to ensure stable ejection and storage of warning assembly 307.

[0042] Warning assembly 307 includes a warning sign 307a, a connecting plate 307b, a stopper 307c, and a first telescopic spring 307d. Warning sign 307a is a striking red sign housed within storage cavity 306b. Its surface can be coated with fluorescent material to enhance visibility at night or in low-visibility environments. A connecting plate 307b is fixedly connected to the left end of warning sign 307a. This connecting plate 307b extends into stopper cavity 306a and is fixedly connected to stopper 307c. Stopper 307c is fixedly connected to the left wall of stopper cavity 306a via a first telescopic spring 307d. The first telescopic spring 307d provides a rebound force, pushing warning sign 307a to pop out quickly after the stopper is released, alerting personnel to the serious risk of subsidence. Its high elasticity ensures long-term reliability.

[0043] The positioning assembly 308 includes a second telescopic spring 308a, a telescopic plate 308b, and four positioning pins 308c, which are fixed to the top wall of the telescopic cavity 306c. The second telescopic spring 308a is made of high-strength spring steel, with its bottom end connected to the telescopic plate 308b. Positioning pins 308c are fixedly installed at the four corners of the bottom end of the telescopic plate 308b. The bottom ends of the positioning pins 308c are inserted into the four positioning slots 307a1 in the warning sign 307a. The positioning slots 307a1 and the positioning pins 308c precisely match, ensuring the stability of the warning sign 307a in the stored state. A gap exists between the bottom end of the positioning pins 308c and the bottom wall of the storage cavity 306b, facilitating the ejection and reset of the warning sign 307a. A slope s is symmetrically provided on the left end of the warning sign 307a, which is in the same vertical plane as the two sets of positioning pins 308c at the front and back. The gradual design of the slope s facilitates the lifting of the positioning pins 308c during reset, simplifying the operation process.

[0044] Lifting assembly 309 comprises a fixed rod 309a secured at the center of movable slot 306d, a rocker plate 309b, and a stopper 309c. Fixed rod 309a is a stainless steel cylinder that serves as a pivot point for rocker plate 309b. Rocker plate 309b is pivotally connected to fixed rod 309a on its outer surface. Its front end extends into telescopic cavity 306c and is positioned directly below telescopic plate 308b, while its rear end extends outside storage frame 306 and is positioned below toggle lever 304. An arcuate groove 309b1 is defined on the upper rear surface of rocker plate 309b, with a stopper 309c fixedly mounted at the end of the groove. This groove guides the movement of toggle lever 304, while the stopper 309c prevents it from slipping out, ensuring the stability of the triggering action. The lifting assembly 309 converts the downward movement of the toggle rod 304 into the upward lifting of the telescopic plate 308b through the lever principle, thereby releasing the restriction of the positioning pin 308c on the warning sign 307a.

[0045] It is worth noting that the outside of the base 100 is fixed with a soft silicone skin 101 by bolts. The soft silicone skin 101 is made of highly elastic, aging-resistant silicone material. It surrounds the outer peripheral side of the base 100 and covers its top. Together with the base 100, it forms a semicircular cavity to accommodate the first-level trigger mechanism 200 and the second-level trigger mechanism 300, providing dustproof, waterproof and pressure-resistant buffer protection. The soft silicone skin 101 is fixed to the reserved holes on the side of the base 100 by bolts. The fixing method is firm and easy to disassemble. Its flexible design absorbs the impact force when the aircraft cabin door is pressed down, protects the internal mechanical and electrical components, extends the life of the device, and adapts to complex environments such as rain, snow, high temperature or dust. A stainless steel handle 102 is fixed to the left end of the base 100. The stainless steel handle 102 is made of corrosion-resistant material to facilitate the transportation and installation of the device. The through hole 102a opened in the center allows the extension of the copper wire 204 to pass through and be electrically connected to the external alarm, ensuring the reliability of signal transmission and environmental adaptability.

[0046] The working principle of this device is as follows: when the aircraft cabin door sinks slightly, the contact plate 202 presses down to compress the contact spring 203, and the contact closure triggers the external alarm to emit an audio prompt through the copper wire 204, reminding the staff to pay attention to the risk of slight sinking; when the contact plate 202 is pressed down too much (such as serious sinking), the secondary warning mechanism is triggered, and the arc-shaped tooth plate 305 on the lower surface of the top of the contact plate 202 engages with the gear cylinder 303, and the arc-shaped tooth plate 305 drives the gear cylinder 303 to rotate forward, and the gear cylinder 303 drives the toggle rod 304 to press forward through the rotating rod 302, and the front end of the toggle rod 304 pushes the rear end of the rocker plate 309b to move downward, and the front end of the rocker plate 309b tilts upward, pushing the telescopic plate 308b to move upward, and the telescopic plate 308b squeezes the second telescopic plate The compression of the compression spring 308a simultaneously drives the four positioning pins 308c at the bottom into the telescopic cavity 306c. When the positioning pins 308c are completely removed from the positioning slots 307a1, the warning sign 307a is released from its position. At this point, the rebound force of the first telescopic spring 307d pushes the stop block 307c to the right. The stop block 307c, via the connecting plate 307b, drives the warning sign 307a to the right. The warning sign 307a extends out of the storage frame 306 and beyond the device, creating a striking visual warning, prompting staff to quickly evacuate the passenger elevator car to avoid the risk of severe subsidence. Simultaneously, the rebound force of the second telescopic spring 308a causes the positioning pins 308c to re-enter the storage cavity 306b, allowing for subsequent reset. The ejection of the warning sign 307a is not only intuitive and reliable, but also, through a mechanical amplification mechanism, transforms minor subsidence into significant movement, enhancing the warning effect.

[0047] When the warning sign 307a needs to be reset to the inside of the device, the staff only needs to push the warning sign 307a into the storage chamber 306b. The tip of the inclined surface s at the left end of the warning sign 307a first passes through the gap between the positioning pin 308c and the storage chamber 306b. The gradual cross-section of the inclined surface s gradually lifts the positioning pin 308c, squeezing the second telescopic spring 308a to compress. When the warning sign 307a completely enters the innermost end of the storage chamber 306b, the four positioning grooves 307a1 are aligned with the bottom of the four positioning pins 308c. The rebound force of the second telescopic spring 308a bounces the positioning pin 308c into the positioning groove 307a1, completing the fixation and storage of the warning sign 307a. The entire operation is simple and quick, and the reset process does not require additional tools, thereby improving operational efficiency.

[0048] In summary, this device achieves a quick audio alarm for slight subsidence through the first-level trigger mechanism 200, and a mechanized visual warning for severe subsidence through the second-level trigger mechanism 300. Combined with the protective and convenient design of the soft silicone skin 101 and the stainless steel handle 102, the device significantly improves the sensitivity, reliability and operational efficiency of passenger elevator settlement monitoring. It is suitable for various civil aviation airports and complex working conditions, providing multiple guarantees for boarding operation safety.
