The invention discloses a tower crane counterweight falling triggering device with a safe idle stroke. Belongs to the technical field of machinery and structurally comprises a detachable counterweight, a safety rope, a wedge-shaped connector, a limiting pin traction connector, a steel wire rope, a cross-shaped transfer beam, a traction rod A, a tow bar frame, a counterweight bracket, a traction rod B, a limiting pin and a guide rail. A connecting rod structure is adopted in the counterweight falling-off triggering device, when the tower crane suddenly unloads and inclines backwards, the draw bar is pulled by the upward lifting displacement of the arm frame, the draw bar separates the counterweight bracket from the falling-off counterweight through the cross adapter beam, and the falling-off of the falling-off counterweight is achieved; and the counterweight falling trigger device has a safe idle stroke, and two insurance ways of the safety rope and the limiting pin are adopted, so that the counterweight can be prevented from falling off by mistake, and the operation safety performance of the super-tonnage tower crane is improved.
本发明公开了一种带有安全空行程的塔机平衡重脱落触发装置。属于机械技术领域,整体结构分别为可脱落式平衡重、安全绳、楔形接头、限位销牵引接头、钢丝绳、十字转接梁、牵引杆A、拖杆架、平衡重托架、牵引杆B、限位销及导轨;本发明中平衡重脱落触发装置采用连杆结构,塔机突然卸载后倾时,利于臂架上扬位移量拉动牵引杆,牵引杆通过十字转接梁将平衡重托架与可脱落式平衡重分离,实现可脱落平衡重脱落;平衡重脱落触发装置带有安全空行程,采用安全绳和限位销两道保险,可避免平衡重误脱出,提高超大吨位塔式起重机作业安全性能。
