Description

Technical Field

[0001] This utility model relates to the technical field of tire abrasion testing, and in particular to an aircraft tire tread rubber abrasion testing machine. Background Technology

[0002] Under harsh conditions such as takeoff, landing, and taxiing, aircraft tires must withstand high temperatures, high speeds, high loads, and complex friction. Their wear resistance directly affects tire life and flight safety. After production, aircraft tires usually undergo a tire wear resistance test before being put into use to check whether the tires meet the qualification requirements. Only when the test results meet the qualification requirements can they be put into use.

[0003] The existing Chinese utility model patent with application number CN202420292496.3 relates to an aircraft tire wear resistance testing device, which includes a base, a tire body, a testing plate, a support rod, a fixing block, an electric push rod, a rotating groove, and a threaded rod, etc., and can provide pressure to the tire and perform testing.

[0004] However, the above-mentioned device cannot simulate different ground surfaces or ground surfaces with different humidity levels in actual use. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an aircraft tire tread rubber abrasion resistance testing machine that improves the practicality of the device by switching between different ground environments through a switching device, providing power through a driving device, and simulating ground under different humidity environments through a spraying device.

[0006] This utility model relates to an aircraft tire tread rubber abrasion resistance testing machine; it includes a switching device, a driving device, and a spraying device. The driving device is installed on the switching device, and the spraying device is also installed on the switching device. The switching device simulates different ground environments, the driving device provides power, and the spraying device simulates ground under different humidity conditions, thus improving the practicality of the device.

[0007] Preferably, the switching device includes a frame, a mounting frame, a geared motor, simulated rollers, and edge chamfers. The mounting frame is mounted in the center of the frame via a rotating shaft, and the geared motor is mounted on the side of the frame. The output end of the geared motor is connected to the rotating shaft on the mounting frame. Multiple pairs of simulated rollers are provided on the side of the mounting frame, and edge chamfers are provided on both sides of the simulated rollers. The simulated rollers provide support to the tire to simulate the ground environment. By turning on the geared motor, power is transmitted to the mounting frame to drive the mounting frame to rotate, rotating the different pairs of simulated rollers to the upper side, thereby quickly switching the simulated ground environment. The edge chamfers provide protection for the tire edges, improving the practicality of the device.

[0008] Preferably, the drive device includes a gantry, a hydraulic cylinder, a lifting frame, a drive motor, and a tire mounting plate. The gantry is located in the middle of the upper end face of the frame, and the hydraulic cylinder is mounted on the upper end face of the gantry. The moving end of the hydraulic cylinder extends through the upper end face of the gantry to the lower part of the gantry and connects with the upper end face of the hydraulic cylinder. The tire mounting plate is located at the lower part of the lifting frame, and the drive motor is mounted on the side of the lifting frame. The output end of the drive motor is connected to the tire mounting plate. When the tire is mounted on the tire mounting plate, the drive motor is turned on to transmit power to the tire mounting plate, causing the tire mounting plate to rotate, thereby simulating the normal operation of the tire. By controlling the extension of the hydraulic cylinder, the height of the tire is adjusted, changing the pressure between the tire and the contact surface, simulating the process of the tire falling and rising, thus improving the practicality of the device.

[0009] Preferably, the spraying device includes spray heads, quick-connect female heads, quick-connect female heads, high-pressure hoses, and a water pump. Multiple sets of spray heads are installed on the side of the mounting frame, each pointing towards a different set of simulated rollers. Multiple sets of quick-connect female heads are also installed on the side of the mounting frame, connecting to the quick-connect female heads. A water pump is installed in the lower part of the frame, and its output is connected to the quick-connect female heads via a high-pressure hose. When the water pump is turned on, external water is pressurized and delivered to the quick-connect female heads, where it is sprayed out from the spray heads, thus humidifying the surface of the simulated rollers and simulating ground surfaces with varying humidity levels. The structure of the quick-connect female and quick-connect female heads facilitates quick installation, disassembly, and replacement, improving the device's practicality.

[0010] Preferably, it also includes an electric cylinder. An electric cylinder is installed on the lower side of the gantry. The moving end of the electric cylinder extends through the gantry and into the gantry to connect with the quick connector head. By controlling the extension and retraction of the electric cylinder, the position of the quick connector head is controlled, so that the equipment can automatically complete the docking and disconnection of the quick connector female head and the quick connector female head, reducing the labor intensity of the operator and improving the practicality of the device.

[0011] Preferably, it also includes linear bearings and limiting rods. A set of linear bearings is installed on the left and right sides of the upper end face of the gantry, and a set of limiting rods is installed on the left and right sides of the upper end face of the lifting frame. The two sets of limiting rods extend through the two sets of linear bearings to the upper side of the gantry. The lifting process of the lifting frame is limited by the linear bearings and limiting rods, which reduces the vibration amplitude of the equipment itself and improves the stability and practicality of the device.

[0012] Preferably, the device also includes safety doors and a water collection tank. Safety doors are installed on the front and rear end faces of the gantry, and a water collection tank is provided at the bottom of the frame. The safety doors seal the test area, improving the safety of the device, while the water collection tank collects the dripping debris and waste liquid, improving the practicality of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by switching the device to simulate different ground environments, by providing power through the drive device, and by simulating ground under different humidity environments through the spray device, the practicality of the device is improved.
