The invention relates to the technical field of tower cranes, in particular to a tower crane overload protection system which comprises an overload protection box and a steel wire rope passing through the overload protection box, and an overload protection device used for monitoring overload of the steel wire rope and fastening the steel wire rope is arranged in the overload protection box; the overload monitor is matched with the guiders to monitor the weight of a load hoisted by the steel wire rope in real time, accidents caused by the fact that the load exceeds the specified weight are avoided, meanwhile, the fastener can fasten the steel wire rope under the matching of the two guiders, and it is ensured that the steel wire is fastened emergently in the emergency braking process; the linkage strip and the connecting strip are matched to drive the U-shaped support and the plane rack to move synchronously, so that the concentric-square-shaped fastening frame is twisted, redundant steel wire ropes generated when the U-shaped support moves towards the concentric-square-shaped fastening frame are wound and fastened on the concentric-square-shaped fastening frame, and it is guaranteed that the steel wire ropes can be smoothly fastened by the concentric-square-shaped fastening frame.
本申请涉及塔式起重机的技术领域,特别是涉及一种塔式起重机过载防护系统,包括过载保护盒和经过过载保护盒内的钢丝绳,所述过载保护盒内设置有用于监测钢丝绳过载以及紧固钢丝绳的过载保护装置;本发明通过过载监测器与导向器的配合实时监测钢丝绳吊运负载的重量,避免负载超出规定重量而出现意外状况,同时在两个导向器的配合下使得紧固器能够紧固钢丝绳,确保在紧急制动的过程中对钢丝进行紧急紧固;本发明通过联动条和连接条的配合驱使U型支架和平面齿条同步移动,以使回型紧固框扭转以便将U型支架向着回型紧固框移动所产生多余的钢丝绳缠绕紧固在回型紧固框上,以确保回型紧固框能够顺利紧固钢丝绳。
