The invention provides a bidirectional clamping mechanism of an aircraft draw bar, and belongs to the technical field of aircraft traction equipment. The technical problem that safety is poor due to the fact that a tractor drags an airplane through a draw bar is solved. The bidirectional clamping mechanism comprises two clamping assemblies arranged at the end of the airplane traction rod, and the two clamping assemblies are arranged in a bilateral symmetry mode and right face to face; each clamping assembly comprises a guide rod head and a sliding groove block fixedly connected with a frame longitudinal beam, wherein a sliding block is arranged on each sliding groove block in a sliding mode, a clamping oil cylinder is arranged between each sliding block and the corresponding guide rod head, the end of a shell of the clamping oil cylinder is hinged to the side face of the sliding block, an output shaft of the clamping oil cylinder is hinged to one side face of the guide rod head, a clamping head is arranged on the other side face of the guide rod head, a clamping notch is formed in the clamping head, and a guide structure is further arranged between the sliding block and the guide rod head. One degree of freedom of the draw bar can be reduced, and the safety of the draw bar for drawing an airplane is improved.
本发明提供了一种飞机牵引杆的双向夹紧机构,属于飞机牵引设备技术领域。它解决了牵引车通过牵引杆牵引飞机的安全性差等技术问题。本飞机牵引杆的双向夹紧机构包括设置在飞机牵引杆端部的两组夹持组件,两组夹持组件左右对称布置且正对设置,夹持组件包括导杆头与车架纵梁固连的滑槽块,滑槽块上滑动设置有滑动块,滑动块与导杆头之间设有夹紧油缸,夹紧油缸的壳体端部铰接在滑动块的侧面上,夹紧油缸的输出轴与导杆头的一侧面相铰接,导杆头的另一侧面设置有夹紧头,夹紧头上具有夹持凹口;滑动块与导杆头之间还设有导向结构。本发明能减少牵引杆一个自由度,提高牵引杆牵引飞机的安全性。
