The invention discloses hoisting equipment for bridge construction and a bridge construction method. The hoisting equipment for bridge construction comprises a walking mechanism, a hoisting mechanism, a first walking mechanism, a power mechanism, a bottom supporting structure and a jacking supporting structure. The hoisting equipment adopts tire type traveling wheels, is small in transverse occupied space, is of a cantilever structure, is longitudinally arranged, can travel in various modes such as transverse, longitudinal and oblique traveling, is not restricted by the completion condition of a bridge main body structure during construction, can realize simultaneous construction of multiple piers and multiple working surfaces, is more flexible, and is convenient to use. The construction efficiency is improved; the hoisting equipment is longitudinally arranged along the bridge, can be supported by means of the jacking supporting structure and the bottom supporting structure, is clear in stress and high in stability and safety, and can be used for installation of prefabricated piers, prefabricated cover beams and prefabricated beam upper structures (such as prefabricated segmental beams), installation and transfer of pier-side brackets, installation of bridge floor ancillary facilities, construction material loading and unloading operation and the like. The comprehensive utilization rate is high.
本发明公开了一种桥梁施工用起重设备及桥梁施工方法,其中桥梁施工用起重设备包括行走机构、起吊机构、第一行走机构、动力机构、底支撑结构和顶高支撑结构。本发明的起重设备采用轮胎式行走轮,横向占用空间少,起重设备为悬臂结构且纵向布置,可以横向、纵向和斜行等多种行走方式,在施工时不受桥梁主体结构完成情况制约,可以实现多个桥墩多个作业面同时施工,更加机动灵活,提高了施工效率;起重设备沿桥梁纵向布设,可借助顶高支撑结构和底支撑结构进行支撑,受力明确,稳定性和安全性高,能用于预制桥墩、预制盖梁、预制梁上部结构(如预制节段梁)的安装、墩旁托架安装及转移、桥面附属设施安装、施工物资装卸作业等,综合利用率高。
