The invention provides an aircraft nose landing gear jacking device, which relates to the technical field of air transportation tool overhaul, and comprises a landing gear support beam, a first lifting mechanism and a second lifting mechanism, the middle of the undercarriage supporting beam is provided with a bearing groove which is sunken downwards, one end of the undercarriage supporting beam is connected to the first lifting mechanism, and the other end of the undercarriage supporting beam is connected to the second lifting mechanism. The first lifting mechanism and the second lifting mechanism are configured to control the two ends of the undercarriage supporting beam to synchronously ascend and descend. The technical problems that in the prior art, when two front wheels of an aircraft landing gear are subjected to steering or other aircraft wheel performance testing, a jack supports the landing gear to occupy the bottom space of the two front wheels, the front wheel performance testing cannot be carried out through an aircraft wheel performance testing device, and the testing efficiency and the testing result accuracy are affected are solved.

    本发明提供一种飞机前起落架顶起装置,涉及航空运输工具检修的技术领域,包括起落架支撑梁、第一举升机构、第二举升机构;起落架支撑梁的中部设有向下凹陷的承载凹槽,起落架支撑梁的一端连接于第一举升机构,起落架支撑梁的另一端连接于第二举升机构;第一举升机构和第二举升机构配置成能够控制起落架支撑梁的两端同步升降。本发明解决了现有技术中,在对飞机起落架两前轮进行转向或其他机轮性能测试时,千斤顶支撑起落架占用两前轮底部空间,造成无法使用机轮性能检测用装置进行前轮性能测试,影响测试效率和测试结果准确度的技术问题。
