[0002] The landing gear of an aircraft has tires that need to maintain a specific air pressure. Inflating and deflating the tires are important items for the maintenance of the aircraft landing gear.

[0003] Inflation requires a high-pressure gas source. If the aircraft has to be driven into a specific maintenance workshop and close to the inflation pipeline every time for tire inflation or deflation, it is undoubtedly very inconvenient. However, the maintenance of aviation equipment is relatively complex and requires the cooperation of various component detections, and the inflation or deflation operations cannot be simply carried out based on the experience of maintenance personnel. In the prior art, there is still a lack of a tire inflation and deflation device with high mobility and capable of accurately cooperating with the detection of the aviation system.

[0015] The technical solution of the utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. Embodiment 1

[0016] like Figures 1 to 2 As shown, the utility model provides a mobile inflatable vehicle, including a vehicle body, an inflatable tank 2, a branch valve 3, a main valve 4, a high-pressure gauge 5, a low-pressure gauge 6, an air plug 7 and an electrical system (not shown); at least one inflatable tank 2 is fixedly mounted on the vehicle body, each inflatable tank 2 is connected to a branch valve 3 through a pipeline, and each branch valve 3 is merged into a main pipeline through a pipeline, and the main pipeline is provided with a main valve 4; the high-pressure gauge 5 and the low-pressure gauge 6 are respectively connected to the front and rear pipelines of the main valve 4; an inflating nozzle 8 is connected behind the low-pressure gauge 6, and an air plug 7 is fixedly provided on the side of the inflating nozzle 8, and an electrical system is fixedly provided on the vehicle body, and the air plug 7 is electrically connected to the electrical system.

[0017] As a high-pressure gas source, the air tank 2 can inflate the tire through its own high air pressure. The gas in the air tank 2 passes through the branch valve 3, the high-pressure gauge 5, the main valve 4, the low-pressure gauge 6, and finally enters the tire through the inflation nozzle 8. When in use, the inflation tube of the landing gear tire needs to be connected to the inflation nozzle 8. At the same time, the pressure sensor of the external pipeline is connected to the aviation plug 7 to cooperate with real-time monitoring of the tire pressure. When the tire pressure is detected to be too low, the branch valve 3 and the main valve 4 are opened to inflate the tire.

[0018] In the above process, the high pressure gauge 5 and the low pressure gauge 6 respectively detect the actual air pressure at both ends of the main valve 4, so that the supply pressure of the inflation tank 2 can be adjusted according to the actual working conditions.

[0019] Specifically, as a preferred embodiment, the vehicle body is composed of a frame 11, a chassis 12, a gas tank bracket 13, a rear wheel 14 and a front wheel 15; the rear wheel 14 and the front wheel 15 are respectively installed at the tail and head of the bottom of the frame 11; the chassis 12 is fixedly arranged at the head of the frame 11, and a pipe bin for accommodating pipes is provided on the chassis 12, and the pipes are arranged in the pipe bin, and a main bin for accommodating an inflation nozzle 8 and an air plug 7 is provided on the side of the chassis 12, and the air plug 7 and the gas nozzle are fixedly installed in the main bin; the gas tank bracket 13 is installed at the tail of the frame 11, and the inflation tank 2 is arranged and mounted on the gas tank bracket 13.

[0020] Preferably, a secondary compartment is provided on the side of the chassis 12, and a hook 9 is provided on the secondary compartment, which can be used to hang some tools, hoses, etc.

[0021] like Figure 3 As shown, as a further preference, the bottom of the gas tank bracket 13 is rotationally connected to the frame 11 via a rotating shaft, and an electric cylinder 18 is hinged on the frame 11, and the gas tank bracket 13 and the frame 11 are movably connected via the electric cylinder 18.

[0022] Generally, the gas tank 2 is tilted and laid on the gas tank support 13 to maintain stability. When the compressed gas in the gas tank 2 is exhausted and the gas tank 2 needs to be replaced, the electric cylinder 18 can be used to prop up the entire gas tank support 13, thereby changing the laying angle of the gas tank 2. This makes it more convenient to lift and move the gas tank 2.

[0023] In order to facilitate the dragging and steering control of the vehicle body 1 as a whole, preferably, the front wheel 15 is mounted on a steering wheel 16, which is rotatably connected to the vehicle frame 11 through a rotating shaft for steering; a handle 17 extending forward is provided on the steering wheel 16. Usually, the entire inflatable vehicle can be conveniently dragged by just holding the handle 17.

[0024] The mobile inflatable vehicle of the utility model has the advantages of high mobility, automation by means of an air plug 7, and simple structure, and can conveniently, automatically, and labor-savingly perform tire inflation and deflation maintenance on an aircraft landing gear.

[0025] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
