The invention discloses a lifter with a built-in support. The lifter comprises a clamping mechanism, a lifting hook connected with the clamping mechanism, a chain rope mechanism connected with the clamping mechanism and a lifting mechanism connected with the chain rope mechanism, wherein the lifting hook is movably connected with the lifting mechanism; the lifting mechanism comprises a connecting rod assembly and a support plate assembly; the connecting rod assembly comprises a pair of upper connecting rods and a pair of lower connecting rods, and the upper connecting rods and the lower connecting rods are connected through second pin shafts; and the support plate assembly is hinged between the pair of lower connecting rods. The distance between an upper base and a lower base is variable, the included angle between the upper connecting rod and the lower connecting rod in each set of connecting rod assembly hinged to the bases is driven to change, the diameter of the rotating center of each support plate hinged to the connecting rod assemblies is changed, the space range expanded by support legs below the support plates is driven to be enlarged, and batch workpieces with different inner diameter hole patterns and sizes can be lifted and carried, so that the application range is wide, and the universality is high.
本发明公开了一种内置支架式提升器,包括夹取机构、与夹取机构连接的吊钩、与夹取机构连接的链索机构、与链索机构连接的提升机构;所述吊钩与提升机构活动连接;所述提升机构包括连杆组件和撑板组件,所述连杆组件包括一对上连杆和一对下连杆,所述上连杆和下连杆通过第二销轴连接;所述撑板组件铰接在一对下连杆中间。本发明的上、下底座的台座间距可变,带动与之铰接的各组连杆组件中上下连杆之间夹角改变,引起与连杆组件铰接的各撑板旋转中心所在直径的大小发生变化,驱使撑板下方的撑脚撑开的空间范围增大,可提升和搬运不同的内径孔型和尺寸的批量工件,应用范围广,通用性强。
