Description

Technical Field

[0001] The utility model belongs to the technical field of airport charging equipment, and in particular relates to a wire-retracting and paying-out device for powering aircraft at an airport. Background Art

[0002] At airports, charging aircraft using aviation ground power carts is crucial for ensuring flight safety and normal operations. When the aircraft is powered by an aviation ground power cart, the aircraft's power cord must be connected to the aircraft via an aviation plug. Because the ground power cart is some distance from the aircraft's parking location, the aircraft's power cord is relatively long, requiring retraction and retraction before and after charging.

[0003] At present, the retraction and release of aircraft power lines are generally done manually, which is not only inefficient but also time-consuming and labor-intensive. Most existing retraction and release devices do not have an automatic cable arrangement function. During the retraction process, the wires will be randomly wound and overlapped on the reel, and easily entangled with each other. This not only affects the subsequent reeling operation and efficiency of the power line, but also easily causes aging or cracking of the outer insulating rubber of the power line, thereby leading to the risk of power output short circuit. Utility Model Content

During the winding process, the wires will be randomly wound and overlapped on the winding roller, which are easy to entangle with each other, which not only affects the subsequent unwinding operation and efficiency of the power line, but also easily causes aging or cracking of the insulating rubber of the power line outer layer, thereby leading to the risk of power output short circuit. The utility model provides a winding and unwinding device for airport aircraft power supply; the motor drives the unwinding roller to rotate to rewind the power line, and cooperates with the guide mechanism to drive the power line to move back and forth along the axial direction of the unwinding roller through the guide mechanism, so that the power line is evenly wound on the unwinding roller, avoiding the problem of easy entanglement of the power line during the winding process, facilitating the subsequent unwinding operation, and being able to realize the automatic wire arrangement function while winding, without the need for manual wire arrangement, significantly reducing labor intensity and improving work efficiency.

[0005] To achieve the above-mentioned purpose, the utility model is implemented through the following technical solutions: a wire-retracting device for powering airport aircraft mainly includes a support plate, a retracting roller, a motor, a guide mechanism, a first rotating shaft, and a chain transmission mechanism.

The support beam is mounted on the support plate by bolts, and a group of positioning rollers are installed on the left and right sides of the support plate. The cross-shaped guide frame is slidably mounted on the support beam through the positioning roller, and a guide groove is vertically opened on the cross-shaped guide frame. The bottom end of the cross-shaped guide frame is hinged with a fixed pulley for limiting the power supply line.

The connecting shaft 403 drives the crank 407 to rotate, and further drives the cross-shaped guide frame 402 to move back and forth laterally on the positioning roller 408, thereby driving the power supply line to move back and forth axially along the retracting roller 2, so that it is evenly wound on the retracting roller 2; avoiding the problem of easy entanglement of the power supply line during the winding process, facilitating the subsequent line-laying operation, and being able to realize the automatic line-arranging function while winding, without the need for manual line-arranging, significantly reducing labor intensity and improving work efficiency.

[0026] When the aircraft needs to be charged, the airport ground staff starts the motor 3, and the motor 3 drives the first rotating shaft 5 to rotate in the opposite direction, and the first rotating shaft 5 drives the retracting roller 2 to rotate in the opposite direction. At the same time, the first rotating shaft 5 drives the second rotating shaft 406 to rotate in the opposite direction through the chain transmission mechanism 6, and the second rotating shaft 406 drives the connecting shaft 403 to rotate in the opposite direction through the active bevel gear 404 and the driven bevel gear 405.
