Supporting and reverse propelling device of shield testing machine

Abstract

The invention discloses a supporting and reverse propelling device of a shield testing machine. The supporting and reverse propelling device comprises the shield testing machine, wherein the shield testing machine is fixedly arranged on a main body base; the supporting and reverse propelling device further comprises a guide groove, a propelling power device and a reverse propelling device with horizontal positioning; the main body base is connected with the guide groove in a sliding way; the propelling power device is connected with the shield testing machine in a transmission way; the guide groove and the propelling power device are both fixedly arranged on a system supporting platform; and the system supporting platform is perpendicularly connected with the reverse propelling device in a sliding way. The supporting and reverse propelling device has the advantages of reasonable structural design, functional diversity, strong generality, strong adaptability to a formation and broad application prospect and can be also used as teaching equipment; and the shield testing machine can be widely applied to simulation of complicated tunnel shield construction conditions.

Description

technical field [0001] The invention relates to the technical field of shield tunneling machines, in particular to a support and counter force propulsion device for a shield tunneling testing machine. Background technique [0002] At present, there are not a few shield testing machines that simulate tunnel shield excavation in China, but most of them have single functions, poor versatility, large volume, high manufacturing and testing costs, and it is difficult to widely use them to simulate complex tunnel shield construction. working conditions. In the prior art, the reaction force propulsion device of the shield machine cannot flexibly adjust the position of the shield test machine, so the simulation test of tunnel excavation cannot be performed at different buried depths and different positions; and the reaction force propulsion device can make the shield test machine and Various geotechnical model boxes have poor combination ability and cannot simulate various complex w...
