Material crane for constructional engineering

Abstract

The invention provides a material crane for constructional engineering, and belongs to the field of material cranes, the material crane for constructional engineering comprises an equipment main body, a lifting push block, a labor-saving rotating plate, a lifting main plate and a rotating bracket, four corners of the equipment main body are fixedly connected with supporting frames; a pneumatic push rod used for driving the lifting push block to vertically slide is fixedly connected to the inner wall of the supporting frame, a driving rotating groove used for driving the labor-saving rotating plate to vertically rotate is movably connected to the top end of the lifting push block, and a driven rotating groove used for driving the lifting main plate to vertically slide is formed in the outer wall of the labor-saving rotating plate. A lifting supporting rod is arranged, in the fine adjustment mechanism, a swing hole plate swings to drive a sliding groove plate fixedly connected with a sliding connecting block to slide horizontally through a sliding hole plate, the sliding groove plate drives the lifting supporting rod fixedly connected with a guide column to slide vertically along a support rotating cylinder through a sliding inclined groove, and leveling operation on the slope pavement equipment body is achieved; the equipment main body can conveniently work on a slope pavement.

Description

technical field [0001] The invention relates to the field of material cranes, in particular to a material crane for construction engineering. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and transports heavy objects horizontally within a certain range. Cranes are used in construction projects. The working characteristics of cranes are intermittent movements, that is, taking materials, transporting them in one working cycle The corresponding mechanisms for moving, unloading and other actions work alternately, and the development and use of cranes in the market are becoming more and more extensive. [0003] However, the existing construction material cranes have the problem that the counterweights cannot be replaced during use, resulting in a small lifting weight of the material cranes, and it is impossible to lift heavy objects of different qualities. When the material crane is in use, there is a problem that the lifti...
