Half-section geotechnical milling machine

Abstract

A semi-cross-section type rock-soil milling-tunneling machine comprises a crawler-type walking mechanism, a rotary supporting platform, an engine located on the platform, a speed changing box, a hydraulic system and a cab and is provide with a cylindrical conical gear case, wherein a drive spindle, a conical gear I and a conical gear II are arranged in the cylindrical conical gear case. A volute-shaped bin and a facing cutter are respectively arranged on two sides of the cylindrical conical gear case, a discharging port is formed in the bottom of the volute-shaped bin, and a worm wheel is arranged in the volute-shaped bin. The cylindrical conical gear case is connected with the rotary supporting platform through a telescopic supporting arm and a supporting arm hinge base, and the telescopic supporting arm is connected with the rotary supporting platform through a horizontal variable-pitch oil cylinder and a vertical variable-amplitude oil cylinder. A telescopic transmission shaft is arranged in the telescopic supporting arm, one end of the telescopic transmission shaft is connected with the conical gear II, and the other end of the telescopic transmission shaft is connected with the speed changing box through a universal joint. The semi-cross-section type rock-soil milling-tunneling machine has the advantages of being high in cutting capacity and production efficiency, high in construction safety, low in exploitation cost, low in energy consumption and the like.

Description

Technical field [0001] The invention relates to a semi-section rock and soil milling machine. Background technique [0002] Full-face tunnel boring machine, namely "shield machine", is a professional tool mainly used for excavating above-ground or underground tunnel engineering. Its problems such as limited application range, low work efficiency, high construction cost and The shortcomings and shortcomings of high energy consumption make it difficult to popularize and apply to large-scale earth and stone excavation, mining, quarrying and other projects. [0003] At present, in the mining of large-scale open-pit mines, the excavation of common building stones, and the excavation of earth and stone, it is common for ore or rocky mountains with hardness grades I to V (that is, extremely hard to medium hard) Drill holes and blast in the mine (rock) first, and then use a "rough breaking" crusher to crush the rock, or use excavators, loaders and other engineering machinery to remove the...

AI Technical Summary

Problems solved by technology

Due to its relatively primitive and backward technical means and construction techniques, there are also geological problems such as high mining risk, high labor intensity, complicated procedures, low production efficiency, high energy consumption, high mining costs, and easy induction of earthquakes and landslides. The Many Disadvantages and Disadvantages of Disasters

[0004] As for the single-bucket excavator, although it has a wide range of applications and its excavation efficiency is very high, it cannot directly excavate those unexploded, relatively hard rocks (such as various hard rocks, hard soils, etc.) and permafrost, etc.)

Similarly, earth-rock construction machinery such as bulldozers and scrapers cannot directly excavate or move this hard rock-soil pile.
