Description

Technical Field

[0001] The present application relates to the technical field of aviation ground support equipment, and in particular to an aircraft tire inflation device. Background Art

[0002] Aircraft tires are mainly used to bear the ground load of the aircraft. When the aircraft takes off and lands, it will generate large impact and vibration loads, and aircraft tires can play a buffering role. The inspection of aircraft tires includes tire inflation and tire pressure measurement. Usually, the inflation tool and the measurement tool are separate.

[0003] The Chinese patent with the authorization announcement number CN206679281U discloses an aircraft tire inflation device, including an inflation and measurement component, and a decompression gas source component connected to the inflation and measurement component through a quick-release joint. The inflation and measurement component includes a cylinder, an inflation valve, a pressure indicator, an inflation tube and a quick-release male joint. The pressure indicator is connected to the other end of the cylinder, and the inflation valve and the inflation tube are arranged on the cylinder. The inflation valve is connected to an inflation handle, one end of the inflation handle is hinged to the cylinder, and the free end of the inflation tube is detachably connected to a quick-fit inflation joint. The two separate inflation and measurement components are combined to form a combined tire inflation and measurement tool component.

[0004] During the application process, it was found that the aircraft tire inflation device is used for the detection and inflation of a single tire. Except for small aircraft, the tires of medium and large aircraft are mostly in pairs. When inspecting aircraft tires, not only is it necessary to keep the tire pressure of the aircraft tires within the standard range, but the tire pressure between paired aircraft tires should also be kept as balanced as possible. Paired aircraft tires are measured and inflated one by one, and the tire pressure is kept balanced by manual meter reading, which is prone to errors. Large errors can easily lead to damage to wheel components, and it is necessary to reduce the difficulty of keeping the tire pressure balanced. Utility Model Content

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The present application embodiment discloses an aircraft tire inflation device. Figure 1 and Figure 2 An aircraft tire inflation device includes an inflation component 1 for connecting to a high-pressure air source and a measuring component 2 connected to the inflation component 1, wherein the measuring component 2 can be connected to multiple aircraft tires.

[0034] The inflation assembly 1 includes a quick-release gas source connector 14 for connecting a high-pressure gas source, a pressure reducer 13 connected to the quick-release gas source connector 14, a connecting pipe 12 connected to the pressure reducer 13, and a quick-release cylinder connector 11 connected to the connecting pipe 12. The quick-release gas source connector 14 is a universal quick-release connector, which is used to connect to a high-pressure gas source such as a nitrogen bottle or a nitrogen tank. The pressure reducer 13 is a component that works on the throttling principle and can reduce the pressure of the high-pressure gas in the high-pressure gas source to the value required for work and stabilize it within a certain pressure range. The quick-release cylinder connector 11 is used to connect to the measuring assembly 2, and the pressure reducer 13 is connected to the measuring assembly 2 through the connecting pipe 12.

[0035] Reference Figure 1 and Figure 2 The measuring assembly 2 includes a connecting cylinder 23 detachably connected to the quick-release cylinder joint 11, a balancing cylinder 21 connected to the connecting cylinder 23, and a plurality of inflation pipes 22 connected to the balancing cylinder 21. The connecting cylinder 23 and the balancing cylinder 21 are integrally processed. The balancing cylinder 21 is arranged at one end of the connecting cylinder 23 away from the quick-release cylinder joint 11. An inflation valve 231 is arranged on the connecting cylinder 23. By switching the inflation valve 231, the balancing cylinder 21 can be connected or disconnected with the quick-release cylinder joint 11.

[0036] Reference Figure 2 and Figure 3 The connecting cylinder 23 is cylindrical, and a strip-shaped cavity is provided inside the connecting cylinder 23. A nozzle adapted to the quick-release cylinder joint 11 is provided at one end of the connecting cylinder 23 away from the balancing cylinder 21. The inflation valve 231 is a press-type air valve, and the inflation valve 231 is arranged in the middle of the connecting cylinder 23. An inflation handle 232 is hinged on the outer wall of the connecting cylinder 23. The pressing rod of the inflation valve 231 is hinged at a position close to the hinged end of the inflation handle 232, so that the inflation handle 232 becomes a labor-saving lever, which is convenient for opening and closing the inflation valve 231.

[0037] A handle 233 for cooperating with the inflation handle 232 is fixedly connected to the outer wall of the connecting cylinder body 23. The handle 233 is arranged at a position away from the hinged end of the inflation handle 232. The operator fixes the handle 233 with one hand and can press or lift the inflation handle 232 more conveniently with the other hand.

[0038] The balancing cylinder 21 is spherical, and a spherical cavity connected to the connecting cylinder 23 is provided inside the balancing cylinder 21. A pressure indicator 211 is provided on one end of the balancing cylinder 21 away from the connecting cylinder 23.

The quick-release inflation joint 222 can be detachably connected to the aircraft tire. The aircraft tire is communicated with the interior of the balancing cylinder 21 through the inflation tube 22. After closing the inflation valve 231, the tire pressure in the aircraft tire can be measured through the pressure indicator 211.

[0040] An air pipe valve 221 is provided at one end of the air pipe 22 close to the balancing cylinder 21. By switching the air pipe valve 221, the aircraft tire can be connected or disconnected with the balancing cylinder 21. Multiple air pipes 22 are connected with the balancing cylinder 21. When the air pipe valve 231 is closed, the multiple air pipes 22 are respectively connected with multiple aircraft tires. When one air pipe valve 221 is opened and the other air pipe valves 221 are closed, the tire pressure of the aircraft tire corresponding to the air pipe valve 221 can be measured by the pressure indicator 211.

[0041] Reference Figure 2 and Figure 3Opening the air pipe valves 221 corresponding to the paired aircraft tires can make the paired aircraft tires communicate with each other and balance the tire pressure between the paired aircraft tires. At the same time, the tire pressure of the paired aircraft tires can be measured by the pressure indicator 211. Opening the inflation valves 231 can inflate or deflate the paired aircraft tires at the same time, and the tire pressure between the paired aircraft tires can be kept balanced, so that when measuring and inflating the aircraft tires, it is convenient to keep the tire pressure between the paired aircraft tires balanced.

[0042] A pressure relief valve 212 connected to the interior is arranged on the outer wall of the balancing cylinder 21. When the air pressure in the balancing cylinder 21 is too high, the gas in the balancing cylinder 21 can be discharged through the pressure relief valve 212, which is convenient for relieving the pressure of the aircraft tire. When the aircraft tire is inflated, when the inflation pressure is too high, the pressure relief valve 212 is opened to avoid damage to the equipment due to excessive inflation pressure.

The universal wheels 41 are provided with brakes 42. A push-pull handle 5 is hinged on the side wall of the frame 4. The push-pull handle 5 and the universal wheels 41 cooperate to conveniently move the frame 4, thereby driving the connecting cylinder 23 and the balancing cylinder 21 to move. The brakes 42 can make the universal wheels 41 stably parked on the ground.

[0044] The implementation principle of the aircraft tire inflation device of the embodiment of the present application is as follows: multiple inflation tubes 22 are connected to the balancing cylinder 21, and the inflation tubes 22 can be conveniently connected to the paired aircraft tires through the quick-release inflation joint 222. The air pipe valve 221 on the inflation tube 22 is opened to facilitate the connection between the balancing cylinder 21 and the paired aircraft tires, so as to balance the tire pressure between the paired aircraft tires. The tire pressure of the aircraft tires connected to the balancing cylinder 21 can be measured by the pressure indicator 211 connected to the balancing cylinder 21, and the pressure relief valve 212 can be opened to release the pressure of the paired aircraft tires, and the tire pressure is kept balanced. The connecting cylinder 23 is communicated with the balancing cylinder 21, the pressure reducer 13 is communicated with the connecting cylinder 23 through the connecting pipe 12 and the quick-release cylinder joint 11, the pressure reducer 13 is communicated with the high-pressure gas source through the quick-release gas source joint 14, and the inflation valve 231 on the connecting cylinder 23 is opened, so that the paired aircraft tires can be inflated, so that when the paired aircraft tires are measured and inflated, the tire pressure of the paired aircraft tires can be kept balanced.
