The invention relates to the field of tower cranes, and discloses a tower crane counterweight falling trigger device with an amplified stroke, the tower crane counterweight falling trigger device comprises a tower body and an arm frame mounted on the tower body, the tower body is movably connected with the arm frame, a balance bracket is mounted at the tail end of the arm frame, a stroke amplification mechanism is mounted on the arm frame, and the stroke amplification mechanism is connected with the balance bracket. A stroke input unit of the stroke amplification mechanism is connected with the tower body through a first traction rope, a stroke output unit of the stroke amplification mechanism is connected with the balance bracket through a second traction rope, and when the arm frame is lifted upwards, the first traction rope drives the stroke input unit to input displacement, the stroke output unit is promoted to output amplified displacement, and the second traction rope drives the balance bracket to output the amplified displacement. And then the second traction rope is driven to pull the balance bracket so that the balance bracket falls off from the arm support.
本发明涉及塔机领域,公开了带有放大行程的塔机平衡重脱落触发装置,包括塔身以及安装在塔身上的臂架,所述塔身与臂架之间活动连接,位于臂架的尾端安装有平衡托架,所述臂架上安装有行程放大机构,行程放大机构的行程输入单元通过第一牵引绳与塔身相连接,行程放大机构的行程输出单元通过第二牵引绳与平衡托架相连接,当臂架上扬时,所述第一牵引绳带动行程输入单元输入位移,促使行程输出单元输出放大的位移,进而带动第二牵引绳拉动平衡托架使其从臂架上脱落。
