The invention belongs to the technical field of aviation machinery, and particularly provides an adjustable trundle supporting system and an adjusting method. The supporting system comprises a trundle, a hydraulic cylinder, a hydraulic support, a hydraulic pump, a first hand control valve, a second hand control valve and a supporting plate, the hydraulic pump is separately connected with the hydraulic support and the hydraulic cylinders through hydraulic pipeline, the first hand control valve is arranged on a hydraulic pipeline between the hydraulic pump and the hydraulic support, and the second hand control valve is arranged on a hydraulic pipeline between the hydraulic pump and the hydraulic cylinder; the hydraulic support is connected with the trundle into a whole through the supporting plate, and the hydraulic cylinders are arranged between the trundle and the supporting plate; and the first hand control valve and the second hand control valve respectively pressurize the connected hydraulic cylinder, so that the purposes of trundle lifting and support lifting are achieved. The invention overcomes the defect that no integrated height-adjustable trundle supporting system exists in the prior art, and provides a height-adjustable trundle device with an independent support; and the structural design is simplified, supporting is stable, safety is improved, and height adjusting time and labor cost are saved.

    本发明专利属于航空机械技术领域,具体提出了一种可调脚轮支撑系统及调节方法,所述支撑系统包括脚轮、液压缸、液压支撑、液压泵、第一手控阀、第二手控阀、支板组成,液压泵分别与液压支撑、液压缸通过液压管路连接,液压泵与液压支撑的液压管路上设置有第一手控阀,液压泵与液压缸的液压管路上设置有第二手控阀;所述液压支撑通过支板与脚轮连为一体,脚轮与支板之间设置有液压缸;第一手控阀与第二手控阀分别对所连接的液压缸进行加压,达到脚轮升降和支撑升降的目的。本发明克服了现有技术中没有一体式高度可调脚轮支撑系统的缺点,提供了一种高度可调,带有独立支撑的脚轮装置;简化结构设计,支撑稳定,提高安全性,节省高度调节时间和人力成本。
