Auxiliary supporting device for digging roadway of coal mine

Abstract

The invention discloses an auxiliary supporting device for digging a roadway of a coal mine. A mobile wheel is arranged below a chassis; a digging component is arranged on a rotary mobile component; the rotary mobile component is slidingly arranged on the chassis; a supporting component is arranged on the rotary mobile component; an auxiliary supporting component is arranged at the top of the supporting component and is used for supporting a to-be-mounted roadway bracket in an auxiliary manner; a removable counterweight component is also arranged on the chassis. According to the auxiliary supporting device disclosed by the invention, an effect of supporting while digging in a process of digging the roadway is realized; in the digging process, dust can be degraded by spraying water mist; the auxiliary supporting component can be used for supporting a supporting beam in an auxiliary manner, the supporting angle is adjustable, and the supporting is flexible; a removable counterweight block is also arranged, so that the supporting and digging effects of the device are ensured, and the balance of the device in the supporting and digging process is ensured, therefore, the roadway digging and supporting efficiency can be greatly improved, and the construction safety is ensured.

Description

technical field [0001] The invention relates to an auxiliary supporting device for coal mine roadway excavation, belonging to the technical field of coal mine roadway excavation and support. Background technique [0002] A coal mine is a reasonable space dug by humans when excavating a geological layer rich in coal, usually including roadways, wells and mining faces. For coal mine roadways, according to the different inclination angles of the roadway, it can be divided into three categories: vertical roadway, horizontal roadway, and inclined roadway. Horizontal roadways mainly include flat tunnels, stone gates, coal gates, and flat lanes. The inclined roadway mainly includes inclined shaft, uphill, downhill and so on. If classified according to the purpose and service scope of the roadway, it can be divided into three categories: development roadway, preparation roadway and mining roadway. The development of roadways refers to the roadways that serve the whole mine or one...

AI Technical Summary

Problems solved by technology

[0003] However, no matter what kind of coal mine roadway, it is generally necessary to excavate and support the roadway during the actual excavation. At present, when the roadway is excavated and supported, the roadway is generally excavated in an orderly manner by a roadheader, and then manually supported. In this way, when supporting, not only the support efficiency is low, but also accidents are often prone to occur. Therefore, it is necessary to design a new type of auxiliary support device that supports while driving, so as to improve the efficiency of support and driving, and improve the quality of coal mines. safety
