The invention discloses a tower crane load trolley pulley fast-assembly structure which comprises a trolley body and a pulley assembly, support plates are fixedly arranged on the two sides of the trolley body, the pulley assembly is provided with a pulley shaft, and U-shaped grooves are formed in the two ends of each support plate. The diameter of the pulley shaft is matched with the width of the U-shaped groove, the two ends of the pulley shaft are placed in the U-shaped groove, clamping plates used for preventing the pulley shaft from rotating are arranged at the two ends of the pulley shaft, and the clamping plates are detachably and fixedly connected with the support plate. When the pulley needs to be replaced, the pulley assembly can be integrally taken out from the upper portion of the U-shaped groove only by loosening the bolt for fixing the clamping plate and taking down the rope blocking device and the clamping plate at the same time, then another set of pulley assembly which is installed in advance is installed on the support plate, the pulley replacement work is completed, the whole replacement process is convenient and rapid, and the working efficiency is improved. And the dangerous action of beating the pulley shaft with a hammer is not needed, so that the safety risk of high-altitude operation is reduced.
本发明公开了一种塔式起重机载重小车滑轮快装式结构,包括小车主体和滑轮组件,所述小车主体两侧固定设置有支架板,所述滑轮组件设置有滑轮轴,所述支架板两端开设有U形槽,所述滑轮轴直径与U形槽宽度匹配且滑轮轴两端放置于U形槽中,所述滑轮轴两端设置有用于防止滑轮轴转动的卡板,所述卡板与支架板可拆式固定连接。当需更换滑轮时,只需将固定卡板的螺栓松开,将挡绳装置连同卡板同时取下,即可将滑轮组件从U形槽上方整体取出,再将已事先安装好的另一套滑轮组件安装在支架板上,即完成滑轮的更换工作,整个更换过程方便、快捷,提高了工作效率,且无需进行用铁锤用力敲打滑轮轴的危险动作,降低了高空作业的安全风险。
