The invention discloses a stable crane used for hydraulic engineering. The stable crane comprises a crane arm, the crane arm is fixedly installed at the upper end of a supporting mechanism, a clampingpiece is arranged at the tail end of the crane arm in a suspended manner through a suspension rope, the supporting mechanism comprises a base cavity, and a lifting bottom plate is arranged at the lower end of the base cavity in a sliding fit connection manner. Walking wheels are installed on the two sides of the lower end of the lifting bottom plate, the clamping piece comprises a cylinder cover,the edge of the upper end of the cylinder cover is connected with the tail end, away from the crane arm, of the suspension rope, an electromagnet is embedded in the center of the top in the cylindercover, and guide rails are embedded in the periphery of the electromagnet in a cross shape. A clamping sliding block is arranged on the corresponding guide rail in a sliding fit manner. According to the device, the lifting bottom plate drives the walking wheels to move up and down, the moving flexibility of the device is improved, an engineering hoisted workpiece is attracted through the electromagnet, the stability of the hoisted workpiece can be improved through cooperation with relative movement clamping of the clamping sliding blocks, and use is safer.

    本发明公开了一种水利工程用稳定吊车,包括吊车臂,所述吊车臂安装固定在支撑机构上端,所述吊车臂末端通过悬挂绳索悬挂设置有夹持件,所述支撑机构包括底座腔,所述底座腔下端滑动配合连接设置有升降底板,所述升降底板下端两侧安装设置有行走轮,所述夹持件包括筒罩,所述筒罩上端边缘和悬挂绳索远离吊车臂的末端相连,所述筒罩内顶部中央嵌入设置有电磁铁,所述电磁铁外围呈十字形嵌入设置有导轨,所述导轨上滑动配合设置有夹持滑块。本发明装置通过升降底板带动行走轮升降移动,提高装置移动灵活性,并且通过电磁铁吸附工程吊装的工件,配合夹持滑块的相对移动夹持,能够提高吊装工件的稳定性,使用更加安全。
