Description

Technical Field

[0001] The utility model belongs to the technical field of deicing equipment, and in particular relates to a liquid-filling platform for a mobile aircraft deicing vehicle. Background Art

[0002] A special vehicle with a self-propelled chassis and a self-propelled boom high-altitude operation equipment at a civil airport and equipped with a spraying system for aircraft de-icing and anti-icing is called a de-icing vehicle. The airport uses de-icing vehicles to spray de-icing and anti-icing fluids on aircraft so that aircraft can meet the release standards in winter (especially in snowy weather conditions). The aircraft de-icing vehicle comes with two liquid filling tanks for de-icing fluid and anti-icing fluid, and the total liquid volume is generally around 5000L-7000L. Based on the average de-icing of 500L per aircraft, under normal circumstances, a de-icing vehicle can only provide de-icing operations for 8-10 aircraft at a time, and subsequent refilling is required. Hangzhou Airport currently has 10 de-icing vehicles, and we have set up two refilling points based on the turnover rate. The ordinary refilling mode is to use a forklift to fork a 1-ton de-icing fluid barrel, and use a diaphragm pump and pipeline to provide refilling for the de-icing vehicle at a height of about 3 meters. Under normal circumstances, it takes 40 minutes to complete the refilling, which is relatively inefficient.

[0003] The Chinese patent document with publication number CN201942509U discloses a mobile liquid filling station with low labor intensity, high safety, and easy control of injection volume. A mobile liquid filling station includes a base, a water tank, a submersible non-clogging sewage pump, and a liquid outlet pipe; the base is provided with front wheels and rear wheels; the mobile liquid filling station also includes a liquid level observation tube, and the liquid level observation tube is provided with a scale. The mobile liquid filling station is equipped with front wheels and rear wheels, and is light and flexible to move; it is equipped with a submersible non-clogging sewage pump, which is driven by a motor to inject liquid into the product or equipment, which reduces the labor intensity of the operator and improves safety; the sewage discharge function of the submersible non-clogging sewage pump can make the liquid injected into the product or equipment cleaner; the liquid level observation tube is made of transparent materials such as plexiglass or glass. Since the liquid level of the liquid level observation tube is at the same height as the liquid level in the water tank, the liquid level variable can be observed through the scale of the liquid level observation tube to control the injection volume.

[0004] When the above patent solution is applied to adding liquid to a de-icing truck, it is necessary to manually carry the end of the filling pipe and climb to the filling port on the top of the de-icing truck, and it is necessary to keep the filling pipe stable during the filling process. Working at height for a long time not only wastes manpower but also increases work risks. In actual working scenarios, the parking direction of the de-icing truck is often not fixed, so the reciprocating movement of the filling pipe is very likely to cause wear and entanglement, which reduces the service life of the filling pipe. Utility Model Content

[0005] In order to overcome the technical problems in the prior art that the de-icing vehicle has a high filling position and the parking position is often not fixed, resulting in inconvenience in filling, a large amount of manual participation and safety risks; one purpose of the utility model is to provide a mobile aircraft de-icing vehicle filling platform, which is connected by rotating a vertical pipe connected to a filling pump on the mobile platform, the lower end of the vertical pipe is located above the de-icing vehicle, and a turntable is provided which can be engaged with the mobile platform and can drive the vertical pipe to rotate, so as to facilitate manual adjustment and locking of the vertical pipe position.

[0008] Furthermore, two ends of the cantilever tube are rotatably connected to the upper end of the rotating tube and the upper end of the vertical tube respectively; and an electric push rod for driving the cantilever tube to rotate is provided on the rotating tube.

[0009] The vertical pipe hangs down under the action of its own gravity, and the cantilever pipe drives the vertical pipe to slide longitudinally, so that the lower end of the vertical pipe can be closer to the filling port to prevent spillage.
