At present, there are general aircraft ground air conditioning air supply hoses, which are used to deliver fresh air with a certain flow, temperature and pressure from the aircraft ground air conditioning to the air conditioning interface of the aircraft fuselage from the air outlet of the air conditioner. However, this type of general aircraft ground air-conditioning air supply hose generally has a length ranging from 10 to 40 meters, and the length is longer. The air duct is sewn in multiple layers, and the weight is heavy. Each flight arrival needs to be unfolded by the airport ground staff. When the flight leaves, it needs to be collected by the airport ground staff, resulting in heavy workload, high work intensity and low work efficiency, which does not meet the requirements of modern automation and improved work efficiency.
This new type of air supply hose for aircraft ground air conditioning is an automatic retractable air supply hose for aircraft ground air conditioning, including a main body of the air supply hose, and a retractable cord is arranged therein. One end of the shrinking rope is fixedly connected to the end of the main body of the air supply hose, and the other end is connected to the shrinking device. The action of the shrinking device pulls the shrinking rope to automatically shrink the main body of the air supply hose.
The aircraft ground air-conditioning air supply hose automatic retracting device includes an aircraft ground air supply hose, an air duct storage cylinder for placing the aircraft ground air supply hose, an air duct retracting mechanism, and a plurality of retracting device implementing mechanisms.
1. Air duct retracting mechanism: one end of its shell is connected to the air duct storage cylinder and automatically retracts the air supply hose. The other end is provided with an air duct arc transition piece. When the aircraft ground air-conditioning air supply hose is retracted, the surface of the air duct passes through the air duct arc transition piece to prevent the aircraft ground air-conditioning air supply hose from being worn and stuck on the surface, and ensures that the automatic retractable device can smoothly retract the air duct.
2. Multiple retractable device actuators, including driven gear, driven gear rotating bearing, driven gear shaft, synchronous belt for retractable air duct, electric motor, driving gear, driving gear rotating bearing and retractable device actuator side plate.
The side plates of the actuators of the two retractable devices are fixed at a fixed distance, a driven gear shaft is installed at one end, and a driven gear rotating bearing and a driven gear are installed on the driven gear shaft. The other end is connected and installed with the motor, and the driving gear rotating bearing and the driving gear are installed on the motor shaft. The outer surfaces of the driven gear and the driving gear are provided with synchronous belts for retracting and releasing air ducts, and the synchronous belts for retracting and releasing air ducts are driven by a motor to realize clockwise or counterclockwise rotation.
There are at least three actuators of the retractable device, and each actuator of the retractable device is evenly surrounded around the air supply hose, and is used for engaging and retracting the air supply hose.
3. Timing belt for retracting and releasing air duct: its inner surface is provided with concave-convex grooves to mesh with the driven gear and driving gear, and its outer surface is provided with concave-convex grooves to mesh with the convex wear strips provided on the outer surface of the air-conditioning air supply hose of the aircraft ground . The driving gear and the driven gear are driven by the motor to rotate, so as to drive the synchronous belt of the retractable air duct to rotate back and forth. Aircraft ground air conditioning supply air hose retracts and extends.
The new aircraft ground air-conditioning air supply hose also includes an air inlet pipe fixed joint and an air pipe storage cylinder end plate, the air inlet pipe fixed joint is connected with the air pipe storage cylinder end plate, and one end of the air inlet pipe fixed joint is located in the air pipe storage cylinder. The inside of the cylinder is connected with the air supply hose of the aircraft ground air conditioner, and the other end is outside the air duct storage cylinder, which is used for connecting with the air supply hose coming from the air supply port of the aircraft air conditioner.
The automatic retractable device for the air supply hose of the aircraft ground air conditioner adopts the motor to drive the main driven gear in the retraction mechanism, the main driven gear drives the synchronous belt, and uses the concave and convex grooves on the outer surface of the same belt to mesh the outer surface of the air conditioner air supply hose of the aircraft The convex wear strips drive the aircraft ground air conditioning air supply hose to shrink and extend.
When the flight arrives, the motor can be used to drive the retractable mechanism to realize the automatic extension of the air supply hose and reduce the workload of the airport ground staff. When the flight leaves, the motor can be used to drive the retractable mechanism to realize the automatic contraction of the air supply hose, reduce the workload of the airport ground staff, reduce the work intensity, and improve the work efficiency, which is in line with the increasing degree of modern automation and work efficiency. requirements.
The automatic retractable device for the air supply hose of the aircraft ground air conditioner can be installed under the boarding bridge or on the ground, which is convenient to automatically realize the extension of the air supply hose of the aircraft ground air conditioner when it is in use, and shrink when it is not in use to realize automatic retraction.
