【技术实现步骤摘要】
一种用于盾构管片翻转吊装的液压式吊具
本技术涉及一种吊具,尤其是用于盾构管片的翻转吊装,属于工程机械吊装领域。
技术介绍
城市地铁建设项目多采用盾构法施工,作为隧道衬砌结构的预制钢筋混凝土管片,其实体质量直接影响盾构隧道的成品质量,因此盾构工程对管片成品质量要求极其严格。现有技术中,为充分利用堆场使用面积,成品管片通常竖立放置于堆场中,但发运时因受力和安全的要求,需将管片进行90°翻转,使管片内弧面向上,水平放置于运输车辆上进行管片的运输。目前在管片的发运吊装领域,传统方式是先用门式起重机将管片起吊至固定式翻片机上,再通过翻片机进行翻转或使用吊带进行二次吊运,这种方式存在吊装过程中极易发生磕碰,操作步骤繁琐,发运吊装效率低下,人力物力投入大等缺点。
技术实现思路
本技术要解决的问题就是针对以上不足,提供一种操作便捷,能大幅度降低管片在吊运过程中发生磕碰概率,有效提高生产效率和满足盾构管片施工要求的装置。其技术方案如下:本技术包括支撑架,其关键技术是在支撑架顶部安装液压推杆,在支撑架底部轴两端和液压推杆顶部分别铰接安装夹具。所述夹具包括夹板和弯芯棒,弯芯棒安装在夹板上,夹板铰接在连接柱上,连接柱分别铰接安装在支撑架底部轴两端和液压推杆顶部。在所述支撑架底部轴中间位置还安装夹具。在所述支撑架上还安装液压泵。在所述支撑架上还安装控制柜。在所述支撑架上还安装平衡块。所述支撑架采用钢板和钢管焊接构成。与现有技术相比,本技术具有的有益效果是:1、它在支撑架顶部安装液压推杆,在支撑架底部轴两端和液压推杆顶部分别安装夹具,结构简单,却能解决管片翻转吊装的大问题。2、将管片的翻 ...
