摘　　要：缆索起重机大型贝雷片塔架常用汽车起重机、履带起重机或塔式起重机等起重设备辅助安拆,由于缆索起重机的塔架较高,常常超过百米,对起重设备起升高度及额定荷载要求较高,故常选用较大型起重设备直至满足吊装要求。然而,大型辅助起重设备租赁费用较高,且随着塔架高度越高,每吊装一次大型贝雷片上下时间较长,工效低,性价比不高。同时,起重设备自身安拆较繁琐,场地要求较高,常需报检,耗时较多。针对上述问题,文中提出一种爬升式摇头杆,可辅助大型贝雷片塔架安拆,改变以往利用汽车起重机、履带起重机或塔式起重机辅助塔架安拆的施工方式,尤其适用于高塔,通过对摇头杆理论计算及现场实际使用效果,对其可行性进行验证。The large beret tower of cable crane is often used to assist hoisting equipment such as truck crane,crawler crane or tower crane in installation and dismantling.The tower of cable crane is relatively high,often exceeding 100 meters,and the hoisting height and rated load of hoisting equipment are high,so larger hoisting equipment is often selected to meet the hoisting requirements.However,the rental cost of large auxiliary hoisting equipment is high,and increases with the tower height,it takes time to hoist a large beret tower,which is inefficient and cost-effective.In addition,the installation and dismantling of hoisting equipment are complicated,the site requirements are high,and it is often time-consuming to apply for inspection.In view of the above problems,this paper puts forward a design of climbing rocker,which can assist the installation and dismantling of large beret tower,change the previous construction method of using truck crane,crawler crane or tower crane to assist the installation and dismantling of tower,and is especially suitable for high towers.The feasibility of the design is verified by theoretical calculation and practical application effect on site.
