Abstract

The invention relates to an accurate automatic excavating device for a model test. The excavating device is favorable for improving the similarity of the model test and an actual project, realizing automation of the model test excavating process and reducing the artificial disturbance influence of manual excavation on a model, so that the monitoring data of the model test are more accurate, and the law in the test is closer to the actual project. The excavating device comprises a cutter, the front side and the periphery of which are used for simultaneously cutting low-strength similar materials; the cutter is connected with a power system through a transmission rod; a hole-type control device is arranged at the rear part of the cutter and at the front part of the transmission rod, the hole-type control device is provided with an arc cutter moving track with toothed edges, the transmission rod is arranged in the cutter moving track and engaged with the inner toothed edge of the cutter moving track through a gear, the gear is also connected with a sleeve sleeved on the transmission rod, the sleeve is provided with scales, and a penetration positioning ring is arranged at the rear part of the sleeve; and meanwhile, a cutter rotating control handle for controlling the rotating speed of the cutter is arranged at the tail end of the sleeve.

Description

technical field

[0001] The invention relates to a model test device, in particular to an accurate automatic excavation device for model tests, which can accurately control the driving depth and hole type in underground engineering model tests. Background technique

[0002] With the development of our country's social economy and the take-off of transportation, the development and utilization of underground space has increasingly reflected huge economic and social benefits. With the continuous increase in the number of underground engineering construction, the scale is increasing, the scope is expanding, and the difficulty of engineering construction is also increasing. The research on the construction and operation rules of underground engineering has become a hot spot. Scientists are also exploring the design, construction and operation rules of underground engineering through various research methods. Among them, it is important to simulate underground engineering through ...
