The invention discloses a wedge block type tower crane counterweight falling-off device. Belongs to the technical field of machinery and comprises a bearing cross beam, a wedge block limiting mechanism, a falling-off balancing weight group, a balancing weight main body, a mounting lug seat, a limiting cross beam, a bearing cross beam main body, a supporting shaft, a limiting wedge block, a limiting plate I, a limiting sliding block, a limiting pin shaft, a fixed lug plate and a balancing weight. A mounting lug is arranged on the left side of the counterweight body; the balance arm is prevented from being impacted; supporting shafts are arranged on the two sides of a cross beam main body, and a limiting wedge block is arranged on the right side of the cross beam main body; the bearing cross beam is mounted on mounting lugs on two sides of the balance arm; the wedge block limiting mechanism comprises a limiting plate I and a limiting sliding block, the fixing lug plate is arranged on the balance arm web member, and the limiting pin shaft is arranged on the fixing lug plate and the limiting sliding block in a penetrating mode; the balancing weight is arranged on the limiting pin shaft in a penetrating mode, the balancing weight is connected with the limiting sliding block support through the chain, and after the limiting pin shaft is pulled out, impact force provided by falling of the balancing weight ensures that the limiting sliding block falls off.
本发明公开了一种楔块式塔机平衡重脱落装置。属于机械技术领域,包括承载横梁、楔块限位机构、可脱落平衡重组、平衡重主体、安装耳座、限位横梁、承载横梁主体、支撑轴、限位楔块、限位板I、限位滑块、限位销轴、固定耳板及配重块;平衡重主体左侧设置安装耳座;避免撞击平衡臂;设置承载横梁来承载可脱落平衡重重力,在横梁主体两侧设置有支撑轴,在右侧设置限位楔块;承载横梁安装在平衡臂两侧安装耳座上;楔块限位机构包括限位板I、限位滑块,固定耳板设置于平衡臂腹杆上,限位销轴穿设于固定耳板与限位滑块上;设置配重块穿设于限位销轴上,配重块与限位滑块支架通过链条连接,在限位销轴拔出后,配重块下坠提供的冲击力确保限位滑块脱落。
