The invention relates to the technical field of cantilever cranes, and provides a pneumatic vertical KBK rotary telescopic cantilever crane which comprises a cantilever mechanism, the cantilever mechanism comprises a fixed cantilever and a rotary cantilever, a traction mechanism is arranged at the bottom of the rotary cantilever, and during working, a suspended object can be displaced in a circle with the sum of the lengths of the fixed cantilever and the rotary cantilever as the radius; by pushing the suspension assembly, the traction mechanism can be driven to rotate through the connecting assembly, so that an object suspended by the lifting hook can be subjected to autorotation to adjust the direction. The traction mechanism further comprises traction frames arranged in the movable frame, the number of the traction frames is consistent with that of the traction ropes, the traction frames correspond to the traction ropes one to one, and the traction frames are used for loosening and winding the traction ropes in the stretching and retracting process of the hydraulic press to ensure that the traction ropes are neat and ordered. And an anti-falling mechanism is arranged in the vertical frame, so that when a hydraulic system breaks down, damage caused by falling of an object and crushing injury to personnel can be avoided, and good safety performance is achieved.
本发明涉及悬臂吊技术领域,提出了一种气动垂直KBK旋转伸缩悬臂吊,包括:悬臂机构包括固定悬臂与旋转悬臂,在旋转悬臂底部设置有牵引机构,在进行工作时,能够对悬吊物件以固定悬臂、旋转悬臂的长度和为半径的圆内进行位移,通过对悬吊组件进行推动,能够带动牵引机构通过连接组件进行旋转,从而能够对吊钩悬挂的物件进行自转调整方位。牵引机构还包括设置于活动框内部的牵引架,牵引架与牵引绳数量一致且一一对应,用于在液压器伸、缩的过程中,对牵引绳进行放松、收卷,保证牵引绳的整齐有序。在立框内部设置有防坠机构,能够在液压系统出现故障时,避免物件下坠出现损坏和对人员造成砸伤,具有很好的安全性能。
