Abstract

The invention discloses a testing device for simulating the tunneling of a shield tunneling machine, and the device comprises a stand. The stand is provided with a sliding guide rail, and a sliding trolley is disposed in the sliding guide rail. The top of the sliding trolley is provided with a bearing seat, and the interior of the bearing seat is rotatingly provided with a rotating shaft. One endof the rotating shaft is provided with a replaceable cutterhead. The device also comprises a tunnel lining model for the tunneling of the replaceable cutterhead. The interior of the sliding trolley isfixedly connected with a first fixed pulley. The device also comprises a support seat fixedly connected to the upper surface of the stand. The top of the support seat is provided with a hook, and a side surface, facing the first fixed pulley, of the support seat is fixedly connected with a second fixed pulley. One end of a sleeve cable is fixedly connected to a hook, and the other end of the sleeve cable sequentially bypasses the first and second fixed pulleys to be connected to a weight hanging disc. The upper surface of the stand is provided with a through groove for the passing of the sleeve cable. The device is more convenient to load a jacking force, and can increase or decrease weights according to different conditions. The device is high in universality, employs the replaceable cutterhead, and can adapt to tunneling simulation excavation tests under different ratios of similitude.

Description

technical field [0001] The invention relates to a shield machine simulation test device, in particular to a test device for simulating the tunneling of a shield machine. Background technique [0002] Shield machine is a kind of special engineering machinery for tunneling. Modern shield boring machine integrates light, mechanics, electricity, hydraulics, sensing and information technology. Measurement-oriented deviation correction and other functions. With the economic development of our country, the original ground transportation system can no longer meet the growing traffic volume. Many cities have begun to take the development and utilization of underground space as an important measure to solve urban congestion, and the proportion of shield tunneling construction is also increasing. However, there will be many problems in the construction of the shield method, so it is necessary to simulate the tunneling process of the shield machine through experiments to determine its...
