Embodiment Construction

[0034] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] exist figure 1 In , the equipment layout of the fully mechanized roadway excavation process based on the robotized excavation, support and anchor unit is given. It can be seen from the figure that the process adopts unmanned intelligent autonomous roadheader 1, self-moving independent temporary support hydraulic pressure Support 2, autonomous positioning and mobile support transport vehicle 3, reloading machine 4, robotic drill and anchor vehicle 5 and belt conveyor 6. The entire excavation roadway can be divided into three areas: front-end excavation area 8 , temporary support area 9 , and permanent anchorage area 10 . Among them, the area where the unmanned intelligent autonomous roadheader 1 cuts the excavation is the front of the entire roadway, which is called the front-end excavation area 8; the position where the sel...

Abstract

The invention relates to a fully-mechanized roadway tunneling process based on a robotized tunneling, supporting and anchoring combined unit. An autonomous tunneling machine, a self-moving hydraulic bracket, a bracket transport cart, a robotized auger anchor cart, a reversed loader and a belt conveyor device are adopted. The process comprises the steps: autonomous tunneling by the tunneling machine; autonomous temporary supporting by the self-moving hydraulic bracket; automatic drilling and anchoring by the robotized auger anchor cart; automatic coal falling and conveying; and dedusting. The process is maximally characterized in that a full-automatic operation of tunneling, temporary supporting and permanent anchoring is achieved by adopting intelligent and automatic tunneling and supporting equipment, and meanwhile, the step of autonomous tunneling by the tunneling machine, the step of automatic drilling and anchoring by the robotized auger anchor cart and the step of autonomous temporary supporting by the self-moving hydraulic bracket are operated reciprocally and parallelly by way of two intermittent steps and one continuous step, so that the tunneling efficiency is improved byabout 2.5 times compared with that in the prior art, and meanwhile, the safety of tunneling, temporary supporting and permanent anchoring is improved greatly.

Description

[0001] The invention belongs to the tunneling technology of fully mechanized tunneling underground in coal mines, and in particular relates to the tunneling technology of fully mechanized tunneling based on a robotized digging, supporting and anchoring unit. Background technique [0002] In recent years, although my country's coal roadway excavation technology has been continuously improved, the degree of automation is still not high, and the excavation efficiency is still very low. Comprehensive excavation method is an advanced roadway excavation technology that has developed rapidly in the past 20 to 30 years. The roadheader integrates the functions of cutting, loading, transfer, and dust reduction. It has high production efficiency, fast excavation speed, and strong adaptability. The advantage of flexible mobilization has greatly improved the working conditions, so it is widely used in the tunneling construction of major coal mines. However, most of the roadheaders in the p...
