Auxiliary support device for tunneling in 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 tunneling in a coal mine, belonging to the technical field of tunneling and supporting in a coal mine. Background technique [0002] A coal mine is a reasonable space excavated by humans when excavating geological layers rich in coal, usually including roadways, shafts, and mining faces. For coal mine roadways, according to the different inclination angles of the roadways, they can be divided into three categories: vertical roadways, horizontal roadways, and inclined roadways. Horizontal roadways mainly include pits, stone gates, coal gates, and level lanes. Inclined roadways mainly include inclined shafts, uphill, downhill and so on. And if classified according to the purpose and service scope of the roadway, it can be divided into three categories: development roadway, preparation roadway and recovery roadway. Opening roadway refers to the roadway that serves the whole mine, or serves one...

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
