The invention discloses a cantilever type lifting device which comprises a chassis and a lifting arm vertically arranged on the chassis, the lower end of the lifting arm is arranged close to one end of the chassis, a turnover supporting leg is arranged at the end of the chassis, the lifting arm comprises a vertical lifting arm and a transverse lifting arm, one end of the transverse lifting arm is arranged at the upper end of the vertical lifting arm, and the other end of the transverse lifting arm is arranged at the lower end of the chassis. A lifting hook is arranged at the free end of the transverse lifting arm, the transverse lifting arm and the vertical lifting arm are both of telescopic arm structures, and after the transverse lifting arm is contracted, the lifting hook can be located in the middle area of the chassis; and the end part of the chassis is also provided with a connecting lug which is hinged with other power devices. The vertical lifting arm, the transverse lifting arm and the lifting hook are arranged on the chassis, the vertical lifting arm and the transverse lifting arm are arranged to be of a telescopic structure and used for rapidly placing an object to be lifted in a roadway to the middle area of the chassis, then the connecting lugs on the chassis are driven by the power device to achieve displacement in the roadway, loading, unloading and transferring are very convenient, and operation is easy. And the dismounting, mounting and transferring efficiency of the protective support in the roadway is greatly improved.
本发明公开了一种悬臂式吊运装置,包括底盘及垂直设置于所述底盘上的吊臂,吊臂的下端靠近底盘的一端设置,底盘端部设有可以翻转的支撑腿,吊臂包括竖吊臂和横吊臂,横吊臂的一端部设置于竖吊臂的上端部,且在横吊臂的自由端设置一吊钩,横吊臂和竖吊臂均为伸缩臂结构,横吊臂收缩后,可使吊钩位于底盘的中部区域;底盘的端部还设有与其它动力装置相铰接的连接耳。本发明采用在底盘上设置竖吊臂、横吊臂及吊钩,且将竖吊臂和横吊臂设置为可伸缩的结构,用于快速将巷道中待吊装的物体放置到底盘的中部区域,然后通过动力装置带动底盘上的连接耳实现在巷道中的移位,其装卸及转运非常方便,大大提高了巷道中防护支架的拆装与转运效率。
