Title: DRILLING AND BURSTING HEADING MACHINE
Abstract:
A drilling and bursting heading machine, comprising a drilling and bursting device (1), an angle control device, a forward-backward telescopic device, and a cantilever type heading machine (2). The drilling and bursting device (1) is mounted on a forward-backward moving component of the forward-backward telescopic device by means of the angle control device; the forward-backward telescopic device is mounted on the cantilever type heading machine (2); the drilling and bursting device (1) comprises a fixing support (1-20), as well as a rock drilling component and a bursting component fixedly mounted on the fixing support (1-20); the angle control device comprises a mounting base (1-15), an auxiliary rotary hydraulic motor (1-14), an adjustment hydraulic cylinder (1-13), and a main rotary hydraulic motor (1-12); when the forward-backward moving component of the forward-backward telescopic device completely extends out, a distance from a front end of the drilling and bursting device (1) to a working plane is less than a distance from a front end of a cutting head of the cantilever type heading machine (2) to the working plane. The drilling and bursting heading machine has a compact structure and is able to quickly implement punching and bursting on a hard rock stratum having a rock hardness greater than 10 without increasing the power consumption, so that the heading efficiency is improved and potential safety risks are reduced.
