Research & Application of Push-Pull Force Testing Technologies for Tunnel Boring Machine
A ball hinge structure is adopted when researching the push and pull testing device of the tunnel drilling rigs,which facilitates the connection between the drill pipe and the testing device and improves debugging efficiency;Due to the high degree of freedom of the ball hinge and no additional torque,the testing accuracy is higher;Transforming the push and pull force into the internal force between the tunnel drilling rig and the testing device has low requirements for the foundation,low cost,and is easy to implement.The electrical system adopts a friendly interface and has the functions of curve drawing,printing reports,or curves.After actual testing,the testing device meets the testing requirements of the tunnel drilling rig.
