Description

Technical Field

[0001] This invention belongs to the field of civil aviation apron operation technology, and in particular relates to an integrated apron operation platform and operation method for serving aircraft ground support operations. Background Technology

[0002] According to existing regulations, when a civil aircraft is parked at its stand, in addition to basic passenger boarding and alighting and baggage handling services, specialized apron vehicles are required to provide corresponding support services. Power supply vehicles provide electricity to the aircraft to meet its needs for starting engines, maintaining internal systems, and charging. Water supply vehicles replenish the cabin water and provide clean water for passengers. Air conditioning vehicles supply clean, cool or warm air at constant pressure, temperature, and humidity to the aircraft's electronics bay, cockpit, and passenger cabins to ensure the performance and lifespan of the aircraft's electronic and electrical equipment, and to provide a comfortable environment for crew and passengers. Therefore, each flight requires at least several ground support vehicles to provide services before takeoff. When the aircraft is parked near its stand for support, the apron space available for vehicle access is limited due to the structure of the jet bridge and other fixed ground equipment. During peak hours, the number of vehicles required for support surges, and the vehicles themselves consume a lot of fuel. The high frequency of support tasks not only increases the workload of ground support personnel, but also increases the probability of safety accidents, further exacerbating the pressure on apron operations and causing environmental pollution such as vehicle exhaust emissions and noise, thereby increasing airport operating costs and reducing its operating efficiency.

[0003] To address the aforementioned issues, relevant organizations have developed multi-functional ground well devices. Integrated ground wells are embedded supply platforms that provide ground energy services for aircraft support, enabling rapid energy supply from underground to the surface. They integrate support functions such as aircraft ground power supply and air conditioning. However, existing ground well devices require simultaneous installation and construction with apron civil engineering projects, which not only results in high engineering costs but also disrupts normal airport operations. Therefore, ground well devices are only suitable for newly built or expanded airports and cannot be widely adopted and applied while ensuring the operation of existing airports. Summary of the Invention

[0004] To address the problems existing in the prior art, this invention provides an integrated apron operation platform and operation method for aircraft ground support services. This reduces the number of support vehicles and ground staff, optimizes apron resource allocation, thereby alleviating apron congestion and minimizing unsafe factors during aircraft parking, taxiing, pushback, and ground vehicle and equipment support operations. This improves the safety of apron operations and the efficiency of apron utilization.

[0005] This invention is implemented as follows: an integrated apron operation platform serving aircraft ground support operations, comprising an operation platform control cabinet installed below the corridor, housing an electric cable winch, an electric water supply winch, and an electric air duct trolley; an operating console, a transformer, a water supply booster pump, and a heat exchanger located outside the control cabinet; the cable of the electric cable winch connected to the transformer, which is electrically connected to the terminal's power system; the water supply line of the electric water supply winch connected to the water supply booster pump, which is connected to the terminal's water supply system; and the electric air duct trolley connected to the heat exchanger, which is connected to the terminal's central air conditioning unit. The control systems of the water supply system, the power system, and the central air conditioning unit are electrically connected to the operating console.

[0006] The control panel is equipped with a voltmeter, a water pressure gauge, a gas pressure gauge, and switches for controlling the operation of the electric cable winch, the electric clean water pipeline winch, and the heat exchanger.

[0007] Water supply lines, power supply lines, and coolant delivery lines for the heat exchanger are all fixed to the underside of the covered bridge.

[0008] The top surface of the control cabinet on the work platform has power line inlet, water line inlet and coolant inlet respectively.

[0009] The operating cabinet of the work platform is a cuboid, with the electric cable winch, electric clean water pipeline winch, and electric air duct trolley arranged in layers inside the cabinet.

[0010] The electric duct trolley can be pushed out of the cabinet when in operation, and the power switch of the electric duct trolley is located on the handle on one side of the trolley.

[0011] The operation platform control cabinet is installed close to the support column of the corridor bridge structure or in the center area of ​​the support column, without occupying the effective usable area of ​​the platform area.

[0012] An operational method for an integrated apron operation platform for aircraft ground support services involves installing an operation platform control cabinet beneath the corridor. Power, water supply, and coolant from the terminal building's electrical system, water supply system, and central air conditioning unit are connected to the operation platform control cabinet via power lines, water supply lines, and coolant delivery lines from the heat exchanger, respectively. Corresponding equipment within the operation platform control cabinet performs aircraft ground support services. The water supply lines, power supply lines, and coolant delivery lines from the heat exchanger are routed and fixed from the bottom of the jet bridge.

[0013] The operation platform control cabinet is installed close to the support column of the corridor bridge structure or in the center area of ​​the support column, without occupying the effective usable area of ​​the apron area, and can ensure the operation of two adjacent machine positions in a staggered manner.

[0014] The advantages and technical effects of this invention are as follows: This invention is an integrated operation platform for aircraft support on the apron. The equipment is designed and installed using the boarding bridge structure between the terminal building and the parking positions. All pipelines and cables are routed and fixed from the bottom of the boarding bridge. The platform is installed close to the support columns of the boarding bridge structure or in the central area of ​​the support columns, without encroaching on the effective usable area of ​​the apron. Installation is simple, the construction period is short, and construction can be carried out without interrupting flight operations, eliminating the need for earthwork. Therefore, this platform can be widely promoted and popularized in major newly built or expanded airports, showing good application prospects. The integrated operation platform can also integrate multiple support service types, including power supply, water supply, and air conditioning supply. The energy or resources required for these services can all be obtained from existing equipment in the terminal building, eliminating the need for additional bulky, costly, and safety-hazardous equipment, thus complying with the requirements of the "Civil Transport Airport Security Facilities" standard. The use of the integrated operation platform reduces the number of support vehicles and ground staff, while improving service support efficiency, alleviating apron operation pressure, thereby reducing environmental pollution such as noise and exhaust emissions, and improving airport operational efficiency.

[0024] The electrical devices, controllers, etc., described in this invention are all conventional setups, and the electrical connections are also conventional connections.

[0025] like Figure 1-4 As shown, the integrated apron operation platform of this invention, which serves aircraft ground support operations, has an operation platform control cabinet installed below the corridor. The operation platform control cabinet is equipped with an electric cable winch 1, an electric clean water pipeline winch 2, and an electric air duct trolley 3. Outside the operation platform control cabinet, there is an operation console 4, a transformer 5, a clean water booster pump 6, and a heat exchanger 7. The cable pipeline of the electric cable winch 1 is connected to the transformer 5, and the transformer 5 is electrically connected to the power system in the terminal building. The clean water pipeline of the electric clean water pipeline winch 2 is connected to the clean water booster pump 6, and the clean water booster pump 6 is connected to the tap water pipeline system in the terminal building. The electric air duct trolley 3 is connected to the heat exchanger 7, and the heat exchanger 7 is connected to the central air conditioning unit in the terminal building. The control systems of the tap water pipeline system, the power system, and the central air conditioning unit are electrically connected to the operation console 4.

[0026] The control panel 4 is equipped with a voltmeter, a water pressure gauge, a gas pressure gauge, and switches for controlling the operation of the electric cable winch 1, the electric clean water pipeline winch 2, and the heat exchanger 7.

[0027] Water supply lines, power supply lines, and coolant delivery lines for the heat exchanger are all fixed to the underside of the covered bridge.

[0028] The top surface of the control cabinet on the work platform has a power line inlet 8, a water supply line inlet 9, and a coolant inlet 10.

[0029] The operating cabinet of the work platform is a cuboid, with the electric cable winch 1, the electric clean water pipeline winch 2, and the electric air duct trolley 3 arranged in layers inside the cabinet.

[0030] The electric duct trolley 3 can be pushed out of the cabinet when in operation, and the power switch of the electric duct trolley 3 is located on the handle on one side of the trolley.

[0031] The operation platform control cabinet is installed close to the support column of the corridor bridge structure or in the center area of ​​the support column, without occupying the effective usable area of ​​the platform area.

[0032] An operational method for an integrated apron operation platform for aircraft ground support services involves installing an operation platform control cabinet beneath the corridor. Power, water supply, and coolant from the terminal building's electrical system, water supply system, and central air conditioning unit are connected to the operation platform control cabinet via power lines, water supply lines, and coolant delivery lines from the heat exchanger, respectively. Corresponding equipment within the operation platform control cabinet performs aircraft ground support services. The water supply lines, power supply lines, and coolant delivery lines from the heat exchanger are routed and fixed from the bottom of the jet bridge.

[0033] The operation platform control cabinet is installed close to the support column of the corridor bridge structure or in the center area of ​​the support column, without occupying the effective usable area of ​​the apron area, and can ensure the operation of two adjacent machine positions in a staggered manner.

[0034] The specific details are as follows:

[0035] Electric Cable Winch 1: This cable winch replaces the traditional power cart to provide power to the aircraft. During use, the aviation connector features control buttons for power on / off and cable retraction / deployment. The cable is automatically retracted and deployed by an internal motor, providing the aircraft with 115V / 400Hz three-phase AC power. This saves manpower, improves operational efficiency, and effectively protects the cable, extending its service life.

[0036] Electric clean water line winch 2: Replaces the clean water truck to replenish the clean water in the aircraft's clean water compartment. Its working principle is similar to a cable winch. Ground support personnel pull out the appropriate length of clean water line according to actual needs and connect it to the aircraft's clean water interface. After the operation is completed, the brushed motor on the winch can be started, driving the winch to automatically retrieve the line.

[0037] Electric duct trolley 3: A device for automatically retracting and extending air supply hoses to aircraft cabins. It is driven by a direct-drive motor and controlled by a switch on the right-hand handle, which drives the drum to rotate, thereby retracting or extending the air supply hose wound on the drum. The retraction and extension speed and angle of the hose can be adjusted. It is small in size and easy to use, improving work efficiency. At the same time, installing the duct device on the trolley can effectively reduce the wear of the hose on the ground and extend the service life of the hose.

[0038] Control panel 4: Equipped with a voltmeter, water pressure gauge, air pressure gauge, and operating switches for the electric cable winch 1, electric clean water pipeline winch 2, and heat exchanger 7. The control systems of the tap water pipeline system, the power system, and the central air conditioning unit are electrically connected to the control module of the control panel and operated by the control panel. Unlike traditional vehicle-mounted mechanical control panels, the control panel of the integrated operation platform can display voltage, water pressure, and air pressure in real time, making it easy for ground personnel to read the progress of the support operation and transmit relevant data to the platform for real-time monitoring. After the support operation is completed, ground personnel can operate the panel to control the brushed motors of each reel to complete the automatic winding and unwinding of each pipeline.

[0039] Transformer 5: Converts the power supplied by the terminal's power system into 115V / 400Hz three-phase AC power to meet the aircraft's needs, maintaining stable output voltage in the event of power instability and improving the safety of charging operations.

[0040] Water purification booster pump 6: It consists of a water purification device and a booster system. The water purification device filters and purifies the tap water delivered from the terminal to the operating platform, and the booster pump provides pressure to deliver it to the aircraft's fresh water tank.

[0041] Heat Exchanger 7: The heat exchanger completes the heat exchange of the coolant and carries it into the air conditioning duct through high-pressure gas generated by the internal compressor, ultimately transferring it to the aircraft cabin. To improve the adaptability and versatility of the platform, considering the high surface temperature in the airport flight area during summer, which can cause electronic components, especially the control panel, to overheat and malfunction; and the fact that temperatures in northern regions drop below freezing in winter, which can not only affect the normal operation of the control devices but also potentially cause the water pipes to freeze, an insulated enclosure is used. In conjunction with the heat exchanger, this maintains a suitable temperature inside the work platform, ensuring normal operation under adverse weather conditions.

[0042] Power Inlet 8: The power supply for the integrated operation platform comes from the existing power system inside the terminal building. The pipeline is led out from inside the terminal building, fixed under the jet bridge, and finally connected to the power inlet of the integrated operation platform to supply power to the operation platform.

[0043] Water inlet 9: The clean water for the integrated operations platform comes from the existing water supply system inside the terminal building. The pipeline is led out from inside the terminal building and is fixed under the jet bridge together with the aforementioned water supply pipeline and coolant supply pipeline. This does not occupy the effective usable area of ​​the apron area, nor does it hinder the normal vehicle passage under the jet bridge. Finally, it is connected to the power supply and water inlet of the integrated operations platform to supply electricity and clean water to the platform.

[0044] Coolant Interface 10: The coolant for the integrated operation platform originates from the central air conditioning unit inside the terminal building. After the coolant pipeline that has completed heat exchange is led out from inside the terminal building, it is fixed under the boarding bridge along with the power supply pipeline and tap water. The energy is transported along the boarding bridge and finally connected to the coolant interface of the platform. After the coolant completes heat transfer, it finally flows back to the central air conditioning unit to achieve the purpose of recycling.

[0045] Cooling source equipment 11: Cooling source equipment maintains indoor air temperature within a comfortable range. It uses refrigerant circulation to cool water and delivers the cooled water to the terminal building's air conditioning system. This equipment typically consists of a compressor, condenser, expansion valve, and evaporator. These components transfer the cooling effect to the terminal equipment of the air conditioning system through a cooling water circulation system to regulate indoor temperature.

[0046] Water pump 12: The water pump pressurizes the cooling water that has completed heat exchange with the cold source equipment so that it can be delivered to the required locations in the terminal building, including air conditioning terminal equipment, cooling towers or cold storage systems.

[0047] Terminal power system 13: The terminal power system is connected to the city's power grid and can provide a stable power supply. Since aircraft have special requirements for power voltage, transformer 7 is connected according to demand to meet the usage conditions of the apron integrated operation platform and provide a stable power input for aircraft.

[0048] Terminal Water Supply System 14: The water source for the terminal water supply system is typically connected to the city's water supply system. The city's water supply system collects water from sources such as reservoirs, rivers, or groundwater, and treats it at a water treatment plant to ensure it meets hygiene standards. The treated water is then transported to the terminal's water supply system through pipelines. Water treated by the water purification booster pump 6 meets the standards for clean water use by aircraft and can be directly injected into the aircraft's clean water tanks via the apron integrated operations platform to provide clean water service to the aircraft.

[0049] Jet Bridge 15: Terminal jet bridges, also known as boarding bridges, are bridge structures connecting the terminal building and aircraft for passenger boarding and disembarking. Terminal jet bridges are typically constructed with a steel frame structure and a glass or metal panel enclosure, possessing sufficient strength and stability to support passenger movement and the weight of the aircraft. The power, water, and coolant input pipes, as well as the coolant return pipes for the apron integrated operations platform, are all routed and fixed at the bottom of the jet bridge. This utilizes the existing building structure, facilitating construction and installation, and does not obstruct normal vehicle traffic, ensuring a high level of safety.

[0050] Fixed end 16 of the boarding bridge joint: The connection between the movable end and the fixed end of the boarding bridge is usually supported by a group of columns or a supporting structure. Installing the integrated apron operation platform in the center of the column group or close to the supporting structure avoids interfering with apron personnel and vehicles, alleviating the pressure on apron operation and scheduling, while facilitating aircraft support operations and avoiding occupying the effective usable area of ​​the apron, thus preventing inconvenience and safety hazards to aircraft support.

[0051] Airport access platform 17: This is the inventive device described in this invention.

[0052] Jet bridge extension 18: Different aircraft models may have different parking positions and heights. The jet bridge extension can be extended, rotated, or height adjusted to accommodate the parking positions and fuselage heights of different aircraft. This ensures that passengers can safely and conveniently enter or exit the aircraft via the jet bridge.

[0053] Power transmission pipe 19: This is the cable drawn out by the electric cable winch 1 and connected to the aircraft power inlet to supply power.

[0054] Air conditioning delivery pipe 20: This is the air conditioning pipe pulled out by the electric air duct trolley 3, which connects to the aircraft air conditioning interface to provide air conditioning service.

[0055] Clean water delivery pipe 21: This is the clean water pipe drawn out by the electric clean water pipeline winch 2, which is connected to the aircraft's clean water interface to supply clean water.

[0056] In the integrated apron operation platform system, the cooling source equipment 11 completes heat exchange with the coolant, and the coolant is pressurized by the water pump 12 and transported along pipelines to the coolant inlet of the integrated apron operation platform. Electricity and clean water are provided by the terminal's electrical system 13 and water supply system 14, respectively. The pipelines for these two energy sources are centrally routed and fixed along the underside of the jet bridge 15, ultimately connecting to the power inlet 8 and water inlet 9 of the integrated apron operation platform. Corresponding devices within the platform provide the aircraft with power, clean water, and air conditioning services. The coolant, after heat exchange, can flow back to the cooling and heating source equipment along pipelines for recycling.

[0057] This invention proposes a "co-linear" concept, whereby energy transmission pipelines connecting the terminal's energy supply system and the integrated platform are uniformly routed and fixed along the bottom of the jet bridge in a unified utility tunnel style. In practice, this can be achieved through drilling for installation, thus avoiding traditional civil engineering work, effectively reducing construction volume and time, lowering overall installation costs, and facilitating airport construction without interrupting operations. Simultaneously, the centralized arrangement of pipelines at the bottom of the jet bridge fully utilizes the space beneath the structure for cabling, occupying less usable space and avoiding interference with other personnel and vehicles on the apron, thereby improving apron operational safety.

[0058] This invention proposes a "common enclosure" concept, integrating power supply, water supply, and air conditioning into a single enclosure to form a comprehensive operating platform. Compared to traditional single-function lift shafts, this platform offers higher integration, simultaneously providing aircraft with power, water, and air conditioning services, thereby improving operational efficiency and enabling rapid resource supply. Furthermore, the enclosure features sufficiently supportive partitions, creating vertical storage space that better accommodates support equipment of varying sizes and provides appropriate isolation between different devices, enhancing the platform's safety and stability. In addition, the common enclosure design reduces the platform's footprint, effectively conserving apron resources.

[0059] This invention platform proposes a "shared" concept, meaning the platform can provide concentrated and rapid energy supply to two adjacent aircraft in a staggered and staggered manner. Addressing the complex resource scheduling and apron vehicle congestion issues faced by adjacent aircraft stands in flight support, this invention platform, when positioned below the pillars at the junction of the fixed and movable ends of the jet bridges of adjacent stands within the harbor area, is close to the aircraft support interfaces of both stands, allowing it to provide services to two aircraft simultaneously. Furthermore, with the advancement and improvement of support technology, this invention platform can integrate more service types, meeting the needs of different aircraft types and apron support services, effectively reducing initial construction costs and apron footprint, optimizing apron resource allocation, alleviating vehicle scheduling pressure, and making it more economical and efficient.

[0060] In this embodiment, the integrated apron operation platform is installed below the columns at the junction of the fixed and movable ends of the jet bridge. All pipelines within the platform are laid along the unused space beneath the jet bridge's structure to ensure no encroachment on other usable areas. Furthermore, the platform's location is close to the columns, minimizing its footprint and preventing interference with the normal dispatching of other special vehicles and personnel on the apron. In addition, when the integrated operation platform is installed at the junction of the fixed and movable ends of the jet bridge in the bay area, its pipeline service range can cover both aircraft on the left and right, providing support services to adjacent aircraft. This reduces the number of special vehicles and ground staff on the apron, as well as the number of pipelines, thereby lowering airport operating costs and environmental pollution, and improving the overall operational safety and efficiency of the apron.

[0061] When an aircraft approaches its parking position, at least two ground support personnel are required to provide ground support services. One person pulls the cables from the platform of this invention one by one to connect them to the corresponding service interfaces on the aircraft, while the other person stays at the integrated operations platform to operate and monitor relevant data such as voltage, air pressure, and water pressure in real time, coordinating to complete the corresponding aircraft support operations, such as replenishing the aircraft's power, providing clean water, and connecting to the external air conditioning system to maintain the cabin temperature. After the support operations are completed, the ground support personnel stationed at the platform can automatically retract the corresponding cables and complete the finishing work through the operating platform. This ground support service model effectively reduces the labor intensity of ground support personnel, simplifies the service support process, thereby improving work efficiency, saving human resource costs, and at the same time, effectively reducing traffic in the apron ground support work area, thereby reducing environmental pollution, optimizing ground resource allocation, alleviating apron space congestion, improving airport operational efficiency, and ensuring the safe operation of aircraft.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
