A New Concrete Polishing System with Lifting Device

Abstract

A novel concrete grinding system with a lifting device comprises a bottom plate, support devices, the lifting device, a buffer device, counterweight devices, a frame device, a fixing device and a grinding device. The bottom plate is provided with a square hole, first through holes, first vertical plates, first fixing blocks and first rolling wheels. Each support device comprises a first supporting rod, a first support, a first motor, a first output shaft, a second support, a second supporting rod and a second rolling wheel. The lifting device comprises a lifting plate, first vertical rods, first positioning rods, first elastic rods, first fixing rods, second fixing rods, first springs, first fixing rings and first stay wires. The buffer device comprises a second fixing block, first connecting rods, third supports, second springs and third springs. Each counterweight device comprises a counterweight. The frame device comprises a frame, fifth supports, a protrusion block and a first friction block. The fixing device comprises a positioning frame, a third fixing rod and a sixth support. The novel concrete grinding system can effectively grinding concrete and is good in grinding effect.

Description

technical field [0001] The invention relates to the technical field of concrete machinery, in particular to a novel concrete polishing system with a lifting device. Background technique [0002] The concrete grinder is suitable for indoor simulation of the grinding effect of automobile tires on highway asphalt pavement, and accelerates the grinding of the aggregate used in the road surface, and evaluates the wear resistance of the aggregate by the measured grinding value of the aggregate. The current concrete grinder has poor polishing efficiency and is inconvenient to move when working. At the same time, the height of the polished structure cannot be adjusted, the depth of concrete grinding cannot be controlled, and there is no buffer protection during grinding. The function of the polished structure is easily damaged and its service life is shortened. [0003] Therefore, it is necessary to provide a new technical solution to overcome the above defects.
