Abstract

The invention relates to an excavator for building a tunnel type passage. The excavator comprises a track type carrying platform, an earth loading box, a wheeled type excavation mechanism, a belt delivery mechanism and a deflection mechanism. The earth loading box is arranged on the rear end of the track type carrying platform; the deflection mechanism is arranged on the front end of the track type carrying platform; the belt delivery mechanism is arranged above the deflection mechanism and is driven to deflect by the deflection mechanism; the tail end of the belt delivery mechanism is arranged above the earth loading box; and the wheeled type excavation mechanism arranged on the front end of the belt delivery mechanism comprises a pair of excavation wheels capable of guiding the excavated earth to a spiral guidance surface of the belt delivery mechanism. The excavator for building the tunnel type passage has the characteristics of high automaticity, low excavation work amount, high excavation efficiency, and adaptation to the emergency rescue service in a collapsed mine.

Description

technical field [0001] The present invention relates to excavation construction machines, and more particularly to excavators for constructing pipeline-type passages. Background technique [0002] At present, in response to sudden disasters caused by mine collapses, there are three main ways to carry out rescue: one is to clean up and reinforce the collapsed site, and open up emergency rescue channels. This rescue method is usually used when the collapsed area is not large. Due to the limitation of the site conditions, it is generally inconvenient to use large-scale professional rescue equipment. Carry out cleaning and reinforcement, and open up emergency rescue passages. The emergency rescue passages are often constructed in the form of wooden pillars and padding materials. The advantages are short preparation time and good mobility; however, it is difficult to clean and reinforce the site, and the degree of mechanization is not high. Large, the rescue efficiency is low, a...
