Semi-cross-section type rock-soil milling-tunneling 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 half-section rock soil milling machine. Background technique [0002] Full-face tunnel boring machine, or "shield machine", is a professional tool mainly used for excavating above-ground or underground tunnel engineering. The shortcomings and shortcomings of energy consumption make it difficult to popularize and apply to large-scale earthwork excavation and mining, quarrying and other projects. [0003] At present, in the mining of large-scale open-pit mines, the mining of ordinary building stones, and earthwork excavation, for ore or rocky mountains with a hardness grade of Ⅰ-Ⅴ (ie: extremely hard to medium hard), people generally Drill and blast the mine (rock) body first, and then use a "coarse crushing" crusher to break the rock, or use construction machinery such as excavators and loaders to remove loose rock (to free up a large area of ​​open space for construction) use) traditional means and methods to carry out proj...

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.
