Problems solved by technology

A large number of scholars have carried out model research on tunnels, but most of the model tests stay in circular tunnels when simulating tunnel excavation, or are excavated manually by hand, and cannot be used for special-shaped (semi-circular, horseshoe-shaped) tunnels. There is a certain gap between the mechanical excavation and the real actual situation. There is a certain gap between the force analysis and the real situation, which leads to a certain deviation between the results of the model test and the possible situation in the real tunnel, which may reduce the Acceptance of model testing
In addition, manual excavation is greatly affected by human factors, and the excavation diameter and inclination angle of the tunnel cannot be very consistent, and it is time-consuming and laborious

Abstract

The application relates to a simulated excavation device for a special-shaped tunnel, comprising: a mechanical arm, an excavation device and a guide rail; the mechanical arm is installed on a base, the base can be placed on the guide rail, and the excavation device is installed at the front end of the mechanical arm; The excavation device includes a closed-loop transmission chain, the central large gear and the transmission gear are arranged in the transmission chain and are respectively meshed with the transmission chain, and the transmission gear and the central large gear are mutually meshed; the outer side of the transmission chain is fixed with a first Soil cutting board, a second soil cutting board is fixed on the side of the central large gear. In the working state, the transmission gear drives the central large gear and the transmission chain to rotate, and the first soil cutting board and the second soil cutting board work The excavation waste soil is driven to the waste soil outlet arranged in the center of the central large gear and discharged. The special-shaped tunnel simulating excavation device of the invention has the characteristics of flexibility, lightness, mobility and easy operation, which can effectively reduce the cost of each test and improve the work efficiency.

Description

technical field [0001] The invention relates to the field of tunnel excavation, in particular to a special-shaped tunnel simulation excavation device. Background technique [0002] With the rapid development of my country's economy, the need to build roads connecting mountainous areas has become urgent. At the same time, the development and utilization of urban underground space also requires people to build tunnels to meet these needs. However, due to the different geological conditions in different places, feasibility test research is often required in the early stage of tunnel construction, and tunnel model test is a more common way. A large number of scholars have carried out model research on tunnels, but most of the model tests stay in the excavation of circular tunnels when simulating tunnel excavation, or are manually excavated, and special-shaped (semi-circular, horseshoe-shaped) tunnels cannot be carried out. There is a certain gap between the mechanical excavatio...
