The invention belongs to the technical field of cranes, and particularly relates to a tower crane lifting steel wire rope detection device which is mounted on a tower crane cross beam. In the specific using process, if signal transmission between a third induction piece and a second motor breaks down, the third induction piece transmits a signal to the second motor, the second motor controls an electric push rod to work, and when the electric push rod drives a sliding frame to move upwards, when the signal cannot be transmitted out, the electric push rod is driven to move upwards. The bottom frame and the sliding frame can clamp the steel wire rope all the time and are driven by the steel wire rope to move, at the moment, the steel wire rope slides towards the side away from the cab relative to the sliding rod, after all pull ropes on the winding wheel are pulled out, the steel wire rope is tightened, a pressing disc on the sliding rod extrudes a second induction piece, and the second induction piece controls an electric push rod to work; and meanwhile, the steel wire rope pulls the limiting rod directly through the sliding rod and the sliding sleeve to relieve limiting on the electric push rod, so that the sliding frame moves upwards relative to the bottom frame, and pressing on the steel wire rope is relieved.

    本发明属于起重机技术领域,尤其涉及一种用于塔式起重机起开钢丝绳检测装置,所述检测装置安装在塔吊横梁上。在具体使用过程中如果第三感应片与第二电机之间的信号传递发生故障,那么在第三感应片将信号传递到第二电机上,第二电机控制电动推杆工作,使得电动推杆带动滑动架上移的过程中,信号传递不出去时,底架和滑动架就会一直夹紧钢丝绳,被钢丝绳带着移动,此时滑动到会相对滑动杆朝着远离驾驶舱一侧滑动,当缠绕轮上的拉绳被全部拉出后,钢丝绳被绷紧,滑动杆上的压盘挤压第二感应片,通过第二感应片控制电动推杆工作,同时钢绳直接通过滑动杆和滑动套拉动限位杆解除对电动推杆的限位,使得滑动架相对底架上移,解除对钢丝绳的压紧。
