The invention discloses a tower crane hoisting area marking system and relates to the technical field of tower cranes. Comprising a camera arranged at the far end of a tower crane boom, an ultrasonic sensor arranged on the side, close to the far end of the tower crane boom, of a tower crane variable-amplitude trolley, an identification device arranged above a tower crane hook, a weighing sensor arranged at the tightening stress position of a steel wire rope of the tower crane hook and a controller arranged in a tower crane cab. An identification system used for controlling the identification device is arranged on the tower crane, the identification system is arranged on the tower crane, after an image below the tower crane is collected, a hoisted object is recognized and analyzed, the identification device is controlled to project an identification to the ground to form an identification area, and the identification area moves along with movement of a crane boom of the tower crane. And the effects that the mark can be projected to the ground in the process of hoisting the object by the tower crane and the constructor can be prompted along with the movement of the hoisted object are achieved.
一种塔吊吊装区域标记系统,涉及塔吊技术领域,包括设置于塔吊起重臂远端的摄像头、设置于塔吊变幅小车靠近塔吊起重臂远端一侧的超声波传感器、设置于塔吊吊钩上方的标识装置、设置于塔吊吊钩钢丝绳绷紧受力处的称重传感器以及设置于塔吊驾驶室内部的控制器,控制上设置有用于控制标识装置的标识系统,通过在塔吊上设置本标记系统通过采集塔吊下方的图像后,对吊装物进行识别分析后控制标识装置投射标识到地面形成标识区域,标识区域跟随塔吊起重臂的移动而移动,达到了能在塔吊吊装物过程中投射标识到地面以及可跟随吊装物移动对施工人员进行提示的效果。
