Height-adjustable box girder hoisting device
The invention discloses a height-adjustable box girder hoisting device, and particularly relates to the technical field of bridge construction, the height-adjustable box girder hoisting device comprises a cross beam, a liquid storage chamber is arranged on the top surface of the cross beam, a lifting chamber is arranged on one side of the liquid storage chamber, a lifting steel rope is wound in the lifting chamber, and a lubricating chamber is fixedly mounted on the bottom surface of the lifting chamber; lubricating liquid enters a spraying head through a telescopic rubber pipe along an outlet, the spraying head wets water absorption cleaning cloth, the outer surface of a lifting steel rope which is lifted and lifted can be lubricated through the water absorption cleaning cloth, the phenomenon that the outer surface of the lifting steel rope is rusted is avoided, an arc-shaped push block and the water absorption cleaning cloth are designed to be of a detachable structure, and the spraying head is convenient to use. Through the design of a bolt piece and a positioning groove, the water absorption cleaning cloth can be replaced conveniently, and the lubricating effect of the lifting steel rope is guaranteed; and the hydraulic cylinder pushes the pressing plate to move, so that the lifting device can adapt to concrete prefabricated workpieces to be lifted at different heights, and the use requirements of various scenes are met.
本发明公开了一种高度可调节的箱梁吊装装置，具体涉及桥梁施工技术领域，包括横梁，所述横梁的顶面设置有储液室，所述储液室的一侧设置有提升室，所述提升室的内部绕接有提升钢绳，且提升室的底面固定安装有润滑室；本发明润滑液顺着出口由伸缩橡胶管进入到喷淋头中，喷淋头对吸水清洁布浸湿，通过吸水清洁布可对提升升降的提升钢绳的外表面润滑处理，避免提升钢绳的外表面出现生锈的现象，弧形推块与吸水清洁布设计成拆卸式结构，通过螺栓件与定位槽的设计，便于对吸水清洁布的更换，保证提升钢绳的润滑效果；通过液压缸推动压板的运动，可适应不同高度的待起吊混凝土预制工件，满足多种场景的使用需要。
