The invention discloses a rope breakage protection device for a tower crane load trolley. The rope breakage protection device comprises a load trolley frame, a fixed steel frame, a reinforced steel frame and a rope breakage protection mechanism. The fixed steel frame is connected with one side of the load trolley frame. The reinforced steel frame is arranged on the side, away from the fixed steel frame, of the load trolley frame. The rope breakage protection mechanism is arranged between the fixed steel frame and the reinforced steel frame and comprises a movable locking rod. A trigger control piece is arranged on the side, away from the load trolley frame, of the movable locking rod. An arc-shaped connecting piece is connected between the load trolley frame and the reinforced steel frame. According to the rope breakage protection device, by changing the mode of carrying out rope breakage protection on the load trolley, the circumstance that the load trolley protection device is disengaged in the using process is reduced, the stability of the load trolley protection device in the using process is improved, the risk that the load trolley shakes in an uncontrollable mode under the situation that an amplitude-variable rope is broken is reduced, and the safety of the load trolley in the using process is improved.

    本发明公开了一种塔机载重小车断绳保护装置,包括:载重车架、固定钢架、加强钢架、断绳保护机构;固定钢架与载重车架的一侧相连接;加强钢架设于载重车架远离固定钢架的一侧;断绳保护机构设于固定钢架与加强钢架之间,断绳保护机构包括移动锁止杆,移动锁止杆远离载重车架的一侧设有触发控制件,载重车架与加强钢架之间连接有弧形连接件。本发明通过改变对载重小车进行断绳保护的方式,减小了载重小车保护装置使用过程中出现固定脱离的情况,提高了载重小车保护装置使用过程中的稳定性,降低了载重小车在变幅绳断裂的情况下出现不可控晃动的风险,提高了载重小车使用过程中的安全性。
