The invention discloses a hand-cranking lifting device for wet joint formwork installation and a construction method. The hand-cranking lifting device comprises a supporting frame and a winding drum, a main shaft of the winding drum is installed on the supporting frame through a bearing, ratchet wheels are installed at the two ends of the winding drum and located on the main shaft, one end of the main shaft is connected with a hand-cranking handle, and the other end of the main shaft is connected with a blocking piece; a ratchet wheel limiting mechanism used for ratchet wheel limiting rotation is installed on the side edge of the upper portion of the supporting frame. The device has the beneficial effects that the action lines of force acting on the main shaft and the bearing are tangent to the main shaft and the deep groove ball bearing according to the wheel shaft principle, the linear speed of the main shaft is increased through the winding drum, the speed of winding and unwinding a steel wire rope is increased, and the operation convenience is improved due to the arrangement of the ratchet wheel limiting mechanism; the hoisting mode that the wet joint formwork is hoisted manually is avoided, the safety during installation of the wet joint formwork is improved, the cost is low, operation is convenient and fast, and the hoisting device can be widely applied to formwork hoisting in the wet joint formwork splicing process.
本发明公开了一种用于湿接缝模板安装的手摇提升装置及施工方法,包括支撑架和卷筒,卷筒的主轴通过轴承安装在支撑架上,卷筒的两端在主轴上均安装有棘轮,主轴的一端连接有手摇柄,主轴的另一端连接有挡片,卷筒绕装有钢丝绳,支撑架上部侧边安装有用于棘轮限位转动的棘轮限位机构。本发明有益效果:本发明通过轮轴原理使作用在主轴和轴承上的力的作用线都与主轴和深沟球轴承相切,通过卷筒放大了主轴的线速度,加快收放钢丝绳的速度,并且设置了棘轮限位机构,增加了操作的便捷性;避免利用人力对湿接缝模板进行吊装的吊装方式,增加湿接缝模板安装时的安全性,成本低、操作便捷,可广泛应用于湿接缝模板拼装过程中的模板吊装。
