The invention discloses a lifting appliance for seabed sand digging and relates to the technical field of lifting appliances, the lifting appliance comprises a bottom frame and an adjusting assembly, a straight rod is connected to the middle of the bottom frame, a sliding groove is formed in the surface of the straight rod, a movable assembly is arranged in the sliding groove, and an expansion assembly is arranged on the outer surface of the movable assembly; the adjusting assembly is connected to the inner wall of the movable assembly, the movable assembly comprises a connecting shaft, a supporting arm, a coupling shaft, an auxiliary arm, a rotating shaft and a mechanical arm, and the supporting arm is connected to the outer surface of the connecting shaft. According to the lifting appliance, the multiple assemblies are arranged in a matched mode, the expansion mode is adopted, the stability of the lifting appliance is improved, the stability of equipment operation is guaranteed through multiple positioning in the same way, the reinforcing assemblies are combined for opening and locking at the bottom, then the connection rigidity of the equipment is reinforced, and by means of the sliding expansion type design, the stability of the lifting appliance is improved. When the equipment is lifted, the heavier the equipment is, the stability of the lifting appliance can be improved, and a user can use the lifting appliance conveniently.

    本发明公开了一种海底挖沙用吊具,涉及吊具技术领域,包括底架和调节组件,所述底架中部连接有直杆,且所述直杆表面设置有滑槽,所述滑槽内部设置有活动组件,且所述活动组件外表面设置有扩张组件,所述调节组件连接于所述活动组件内壁,所述活动组件包括连接轴、支臂、联轴、辅助臂、转轴和机械臂,且所述连接轴外表面连接有所述支臂。本发明通过采用多个组件之间的相互配合设置,利用扩张式的方式,不仅提升了吊具的稳定性,同理利用多重定保障了设备运行的稳定性,并结合加固组件在底部撑开锁住,进而加固了设备的连接刚性并利用滑动扩张式的设计,使得在吊装设备时设备越重能够提升吊具的稳定性,方便使用者使用。
