[0002] Aircraft tires are the core component of aircraft landing gear, and their design and performance are directly related to flight safety. Aircraft tires are usually made of high-strength rubber, nylon or aramid fiber, and the tire carcass structure contains multiple layers of cord to withstand high pressure and impact.
[0003] Existing vulcanizing machines, such as the multi-station tire partial vulcanizing machine disclosed in utility model patent application number 201920946943.1, mainly include a workbench and a control cabinet. A supporting vertical shaft is provided at the center of the top of the workbench, and an annular mounting seat is provided around the top of the workbench. A supporting device is fixed on the supporting vertical shaft, which can support the inner ring of the tire and fix it on the supporting device. In use, the tire is put on the supporting device and the supporting device is adjusted to support the inner ring of the tire and fix it on the supporting device. Raw rubber containing vulcanizing agent is filled into the position that needs vulcanization repair. According to the position to be repaired, a corresponding number of heating units are installed on the annular mounting seat, and the heating units are used to simultaneously vulcanize and heat each position.
[0004] However, most existing vulcanizing machines require manual handling for loading and unloading. Aircraft tires are large in size, and manual handling is time-consuming and labor-intensive. Moreover, harmful gases are generated during the vulcanization heating process, and allowing them to be emitted will affect the air quality inside the factory. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a multi-station partial vulcanizing machine for aircraft tires that can not only drive the loading and unloading of aircraft tires, improving work efficiency and eliminating the trouble of manual handling, but also extract, collect and treat the harmful gases generated during the vulcanization process to prevent them from spreading and affecting the air quality in the factory.
[0006] This utility model discloses a multi-station partial vulcanizing machine for aircraft tires, including a protective mechanism; it also includes a conveying mechanism, a lifting mechanism, a fixing mechanism, an extraction mechanism, and a heating mechanism. The conveying mechanism is installed on the protective mechanism and drives the aircraft tires to be loaded and unloaded.
