Abstract

A shield cutterhead vibratory excavation experiment table disclosed by the present invention comprises a shield cutterhead, a soil basin, a soil basin fixing device, a soil basin pushing up device, aspindle kit and an overall steel rack. The spindle kit is installed on the overall steel rack, the shield cutterhead is installed at the lower part of the spindle kit, the soil basin fixing device isinstalled on the soil basin pushing up device below the shield cutterhead and is driven by the soil basin pushing up device to move up and down, and the soil basin pushing up device is installed on the overall steel rack. According to the present invention, the rotating speed of the shield cutterhead and the propulsion speed of the soil basin both can be controlled by a motor real-timely, so thata non-uniform speed shield excavation experiment can be realized. According to the present invention, a torque sensor and an electronic scale obtain the change of the torque and the propulsive force,on one hand, the change of the torque and the propulsive force of a cutterhead can be tested under the vibration action, on the other hand, the dynamic characteristics of the shield cutterhead also can be experimented under the speed change, namely, along with the change of the speed and the acceleration, the torque and the propulsive force change.

Description

technical field [0001] The invention relates to experimental equipment for testing the effect of vibration excavation, and more specifically, relates to a vibratory excavation test bench for a shield cutter head. Background technique [0002] The main function of shield equipment is tunnel excavation, which can make important contributions to the development of urban and rural areas in contemporary China. In contemporary large cities with a large population and vehicles, such as Beijing, Shanghai, Hangzhou, Guangzhou, etc., the demand for subways is getting higher and higher, and the excavation of modern subway tunnels uses shield machines as excavation equipment, which brings The demand for shield equipment is also increasing. However, in China’s remote rural areas, such as Guangxi and Sichuan, there are many mountains. If these areas want to develop, they must first establish good transportation with the outside world. To build a tunnel, this requires advanced shield equ...
