Description
Technical Field
[0001] The utility model belongs to the technical field of aircraft fuel vehicle maintenance, in particular to an auxiliary oil receiving device for repairing and maintaining a refueling joint of an aircraft refueling vehicle. Background Art
[0002] Existing fuel receiving equipment for aircraft refueling truck maintenance is typically designed and used to provide a direct, sealed connection to the truck's oil drain pipe. While this connection effectively prevents fuel leaks, in practice, friction and vibration at the connection often cause severe wear and tear on the refueling truck's oil drain pipe head. This wear not only shortens the drain pipe's service life but can also lead to safety hazards such as fuel leaks, posing a threat to aircraft refueling operations and airport safety.
[0003] The wear problem is mainly caused by the following factors: first, the friction between the oil drain pipe and the oil receiving device; second, the vibration generated by the refueling truck during operation. In addition, if the oil receiving device is unreasonable in design or improperly installed, it may also aggravate the wear of the oil drain pipe head.
[0004] Therefore, in view of the problem that the above-mentioned existing aircraft refueling truck maintenance oil receiving equipment is directly and sealedly connected to the refueling truck's oil drain pipe, causing serious wear of the refueling truck's oil drain pipe head, an auxiliary oil receiving device for the repair and maintenance of the aircraft refueling truck's refueling joint can be designed. Utility Model Content
[0005] In order to overcome the problem that the existing oil receiving equipment for aircraft refueling truck maintenance is directly and sealedly connected to the oil drain pipe of the refueling truck, causing serious wear of the oil drain pipe head of the refueling truck.
[0006] The technical solution of the utility model is as follows: an auxiliary oil receiving device for repairing and maintaining a refueling joint of an aircraft refueling truck includes an oil tank assembly, a vehicle frame, wheels, and a pump assembly; a vehicle frame is provided at the lower end of the oil tank assembly, and the vehicle frame and the oil tank assembly are fixedly connected; a pump assembly is provided at the front end of the oil tank assembly; a wheel is provided at the lower end of the vehicle frame; the oil tank assembly includes an oil tank, an upper cover, a clean and sealed tank door, and an oil drain pipe valve; the pump assembly includes a pump, an oil drain pipeline, an oil suction pipe, a counterweight plate, a spherical head, and an oil suction hole.
[0007] Preferably, the oil suction pipe of the pump assembly is put into the oil tank of the refueling truck. Since the density of the counterweight plate is consistent with that of the fuel and the shape of the spherical head is matched, the counterweight plate will not sink to the bottom and be adsorbed on the inner wall of the container to hinder the pumping of oil, thereby effectively improving the fuel transfer speed and avoiding the use of the oil drain pipe joint of the refueling truck, thereby increasing the service life of the oil drain pipe joint structure, and solving the problem of existing oil receiving equipment for maintenance of aircraft refueling trucks, because it is directly and sealedly connected to the oil drain pipe of the refueling truck, causing serious wear of the oil drain pipe head of the refueling truck.
[0008] Preferably, an upper cover is provided at the upper end of the oil tank, and the upper cover is sealed to the oil tank shaft flange; a clean and sealed tank door is provided at the rear of the oil tank, and the clean and sealed tank door is sealed to the oil tank shaft flange.
[0009] Preferably, an oil drain pipe valve is provided at the rear end of the cleaning and sealing tank door, and the oil drain pipe valve is connected to the interior of the oil tank, and a valve module is provided inside the oil drain pipe valve.
[0010] Preferably, a pump is provided at the front end of the oil tank, and the outer shell of the pump is fixedly connected to the frame; an oil drain pipeline is provided at the output end of the pump, and one end of the oil drain pipeline is connected to the interior of the oil tank.
[0011] Preferably, an oil suction pipe is provided at the input end of the pump, and the oil suction pipe is connected to the input end pipeline of the pump.
[0012] Preferably, a spherical head is provided at the input end of the oil suction pipe; an oil suction hole is provided on one side of the spherical head, and the oil suction hole is connected to the oil suction pipe.
[0013] Preferably, a counterweight plate is provided on the outer side of the spherical head, and the counterweight plate is fixedly connected to the oil suction hole, and the density of the counterweight plate is equal to the density of the aircraft fuel.
[0014] Beneficial effects of the utility model:
[0015] 1. Existing aircraft refueling truck maintenance oil receiving equipment, which directly and sealably connects to the refueling truck's oil drain pipe, causes severe wear and tear on the refueling truck's oil drain pipe head. This system pumps the oil into the refueling truck's oil tank through the pump assembly's suction pipe. Because the density of the counterweight plate is consistent with the fuel and the shape of the spherical head matches the fuel, the counterweight plate will not sink to the bottom of the container and adhere to the inner wall, hindering oil pumping. This effectively improves fuel transfer speed and avoids the use of the refueling truck's oil drain pipe joint, extending the service life of the oil drain pipe joint structure. This solves the problem of existing aircraft refueling truck maintenance oil receiving equipment, which directly and sealably connects to the refueling truck's oil drain pipe, causing severe wear and tear on the refueling truck's oil drain pipe head.
[0016] 2. By setting the cleaning sealed tank door and the oil drain pipe valve, the oil drain pipe valve of the cleaning sealed tank door is used to discharge fuel to the outside. When the fuel inside the tank is drained and needs to be cleaned, the cleaning sealed tank door can be opened to clean the inside of the tank, which greatly improves the cleaning efficiency of the inner wall of the tank, facilitates multiple uses and reduces the generation of fuel impurity deposition.

[0024] See also Figure 2In this embodiment, an upper cover 102 is provided at the upper end of the oil tank 101, and the upper cover 102 is sealed with the oil tank 101 shaft flange; a clean and sealed tank door 103 is provided at the rear of the oil tank 101, and the clean and sealed tank door 103 is sealed with the oil tank 101 shaft flange; an oil drain pipe valve 104 is provided at the rear end of the clean and sealed tank door 103, and the oil drain pipe valve 104 is connected to the interior of the oil tank 101, and a valve module is provided inside the oil drain pipe valve 104; a pump 401 is provided at the front end of the oil tank 101, and the shell of the pump 401 is fixedly connected to the frame 2; the pump 401 An oil drain pipe 402 is provided at the output end, and one end of the oil drain pipe 402 is connected to the interior of the oil tank 101; an oil suction pipe 403 is provided at the input end of the pump 401, and the oil suction pipe 403 is connected to the input end pipeline of the pump 401; a spherical head 405 is provided at the input end of the oil suction pipe 403; an oil suction hole 406 is provided on one side of the spherical head 405, and the oil suction hole 406 is connected to the oil suction pipe 403; a counterweight plate 404 is provided on the outside of the spherical head 405, and the counterweight plate 404 is fixedly connected to the oil suction hole 406, and the density of the counterweight plate 404 is equal to the density of aircraft fuel.
[0025] During operation, oil is pumped into the fuel tank of the refueling truck through the oil suction pipe 403 of the pump assembly 4. Since the density of the counterweight plate 404 is consistent with that of the fuel and the shape of the spherical head 405 is matched, the counterweight plate 404 will not sink to the bottom and be adsorbed on the inner wall of the container to hinder oil pumping, thereby effectively improving the fuel transfer speed and avoiding the use of the oil discharge pipe joint of the refueling truck, thereby increasing the service life of the oil discharge pipe joint structure.
