An automatic tunnel drilling rig for coal mines

Abstract

The invention provides an automatic tunnel drilling machine for coal mines, which includes a shell, an inner bin, a counterweight, a column, a fixed column frame ring, a wheel body bracket, a circular groove gear, an inner hole of a drill rod and an auxiliary groove; There is an inner compartment; one side of the motor slider is provided with fixed bolts through screw holes; the outer side of the drill floor shaft is fixed with a pulley B through a key connection; one side of the drill floor is provided with an annular groove, and the ring There is a fixed ring fixed by using screws to install the locking ring in the groove; taper bolts are installed on the inner side of the tightening fixed column by setting threads, and there are two sets of guide grooves on both sides of the taper bolts. By setting the guide grooves, the tightening The fixed column is guided, so that the tapered bolt in the middle of the fixed column is inserted into the position of the underground fixed shell to enhance stability.

Description

An automatic tunnel drilling rig for coal mines technical field The invention belongs to machinery, coal mine equipment technical field, more specifically, particularly a kind of coal mine automation pit Road rig. Background technique Tunnel drilling rig is a drilling rig specially used for drilling in underground tunnels (tunnels), mainly used in tunnels (tunnels) The construction of deep geological exploration, gas drainage, injection and drainage, ventilation and other projects is carried out inside, through the internal pipeline of drill pipe. The underground is used for environmental detection in the detection area, and the drill pipe is inserted into the soil through mechanical force transmission such as a motor for operation. do.
