The invention discloses a tower crane capable of resisting wind power swing. Reinforcing assemblies are connected to the middles of the supporting frames. Suspension arms are connected to the upper sides of the reinforcing assemblies; the right side of the cab is connected with an extension assembly; in strong wind weather, the first crankset and the second crankset are matched to lock the cylinder, the phenomenon that the suspension arm swings after being impacted by strong wind is avoided, potential safety hazards are reduced, the barbs on the first crankset and the second crankset are both arranged in two directions, the cylinder is locked in two directions, and compared with one-way barbs, the fixing stability is higher, and the stability is higher. Under the cooperation effect of a first linkage block and a second linkage block, the strong wind impact force borne by the suspension arm cannot be transmitted to a telescopic air cylinder used for driving, the problem that the telescopic air cylinder is damaged due to reciprocating extrusion force is avoided, when workers need to obtain the view field, a pedal is automatically retracted to the inner side wall of a cab, and the safety of the workers is improved. Workers can obtain the visual field below the cockpit through the transparent part, and the problem that existing equipment cannot quickly obtain the visual field below is solved.
本发明公开了一种抗风力摆动的塔式起重机;支撑架中部连接有加固组件;加固组件上侧连接有吊臂;驾驶舱右侧连接有扩展组件;强风天气时,通过第一牙盘与第二牙盘相配合,将圆柱锁紧,避免吊臂受到强风冲击后出现摇摆现象,降低安全隐患,并且第一牙盘和第二牙盘上的倒钩均为双向设置,从而从两个方向上将圆柱锁紧,相比于单向的倒钩固定稳定性更高,而且通过第一联动块与第二联动块的配合作用下,吊臂受到强风冲击力并不会传导至用于驱动的伸缩气缸上,避免伸缩气缸因受到往复挤压力而损坏的问题,工作人员需要获取视野时,自动将踏板收起至驾驶舱内侧壁,使工作人员透过透明件获得驾驶舱下方视野,避免了现有设备无法快速获取下方视野的问题。
