Material lifting device for building construction based on locking and clamping structure

The utility model relates to a material lifting device for building construction based on a locking and clamping structure. The material lifting device comprises a bottom plate, an objective table, a telescopic base, a hanging ring and a clamping mechanism. The telescopic seat is fixed on the bottom plate, an objective table is fixed on the telescopic seat, and an objective area is arranged on the objective table; the telescopic base is sleeved with a reset spring. A guide long hole is formed in the objective table, and a guide rail is arranged in the guide long hole; the clamping mechanisms are symmetrically arranged on the two sides of the objective table. The problems that a clamping structure on an existing lifting base is complex in operation, and clamping force is limited by external supply are solved, self-locking clamping is achieved through the dead weight of a load, when materials are placed on an object carrying area, the object carrying table can move downwards due to the gravity of the materials,
