The embodiment of the invention provides an aircraft dragging wheel for a skid type helicopter. One end of a main wheel carrier of the aircraft dragging wheel is fixedly installed on a connecting shaft, and the other end of the main wheel carrier is fixedly installed at a first preset position of a handle; two ends of the connecting shaft are respectively connected with a wheel; a first mechanicalclaw is fixedly installed at one end of each handle through an adapter, and a second mechanical claw is fixedly connected to the second preset position of the other end of the adjacent handle throughan installation assembly. The open end of the first mechanical claw is used for grasping the undercarriage, the first mechanical claw is provided with a first locking part, and under the condition that the first mechanical claw grasps the undercarriage, the first locking part is in a locked state; and the open end of the second mechanical claw is used for grasping the undercarriage, the second mechanical claw is provided with a second locking part, and the second locking part is in a locked state under the condition that the second mechanical claw grasps the undercarriage. By applying the scheme of the embodiment, the reliability can be improved on the basis of ensuring that the structural strength of the undercarriage is not damaged.

    本发明实施例提供了一种用于滑撬式直升机的拖机轮,该拖机轮的主轮架的一端固定安装在连接轴上,另一端固定安装在手柄的第一预设位置处;连接轴的两端分别连接一个车轮;手柄的一端部通过转接件固定安装第一机械爪,且在相邻手柄的另一端部的第二预设位置上通过安装组件固定连接有第二机械爪;第一机械爪的开放端用于抓紧起落架,且第一机械爪设有第一锁紧件,在第一机械爪达到抓紧所述起落架的情况下,第一锁紧件处于锁住状态;第二机械爪的开放端用于抓紧起落架,且第二机械爪设有第二锁紧件,在第二机械爪达到抓紧所述起落架的情况下,第二锁紧件处于锁住状态。应用本实施例的方案能够在保证不破坏起落架结构强度的基础上,能够提高可靠性。
