AI Technical Summary
When the existing cement concrete core collector is cut through the cement concrete pavement, the collision between the knife head and the pavement causes the core collector to shake, affecting the quality of the core sample. Especially for small-body operators, the large shaking of the fuselage may cause the core sample to break, and the shaking of the bracket will also cause discomfort to the operator.
A self-balancing device of a cement concrete core collector is designed, including a bracket and a counterweight module. The counterweight module consists of multiple strands of wire rope, annular tray and annular counterweight blocks. Through the design of these components, the stability of the bracket is enhanced, thereby reducing the shaking of the core collector.
By enhancing the stability of the bracket, the shaking of the core machine is reduced, the core sample breakage is effectively avoided, the core sample integrity is improved, and the operator's discomfort caused by the shaking of the bracket is reduced.

However, due to the different body shapes of the operators, the degree of shaking of the coring machine is also different. For small-sized operators, there is still a situation where the core sample breaks due to the large shaking of the machine body. In addition, the shaking of the bracket can easily cause discomfort to the operator. Utility Model Content
