The invention provides a tensioning mechanism and engineering mechanical equipment, and belongs to the technical field of engineering mechanical equipment, and the tensioning mechanism comprises a mounting frame, a tensioning device, a tensioning device, a tensioning device, a tensioning device and a tensioning device, and the mounting frame is provided with a through groove suitable for sliding and a guide groove communicating with the through groove; the driving part is arranged in the guide groove in a sliding mode, and is suitable for penetrating through the guide groove and abutting against a part to be tensioned in a contact mode; and the tensioning cam is eccentrically and rotationally connected to the mounting frame through a first rotating part, and the tensioning cam is in contact with and abuts against the driving part. According to the tensioning cam, the driving part is pushed to slide along the guide groove through eccentric rotation, and the driving part directly or indirectly abuts against the to-be-tensioned part to achieve tensioning of the to-be-tensioned part; according to the tensioning structure, the driving part is pushed to act through rotation of the tensioning cam, the mode that oil is injected into the oil cylinder to drive the piston to stretch out and draw back is replaced, the structure is simple, cost is low, and the influence on other parts caused by oil leakage is avoided.

    本发明提供的一种张紧机构及工程机械设备,属于工程机械设备技术领域,包括:安装架,具有适于滑动的通槽以及与所述通槽连通的导向槽;驱动件,滑动设于所述导向槽内,适于穿过所述导向槽并与待张紧部接触抵接;张紧凸轮,通过第一转动件偏心且转动地连接在所述安装架上,所述张紧凸轮与所述驱动件接触抵接。本发明提供的张紧凸轮通过偏心转动来推动驱动件沿导向槽滑动,驱动件与待张紧部直接或间接抵接,来实现对待张紧部的张紧;上述的张紧结构通过张紧凸轮旋转推动驱动件动作,来代替向油缸内注油来驱动活塞伸缩动作,结构简单、成本低,并且避免漏油造成对其他零部件的影响。
