Automatic rock drilling device special for tunnel excavation

Abstract

The invention relates to an automatic rock drilling device special for tunnel excavation, which has high rock drilling efficiency, is safe for using and contributes to saving time and construction cost. The automatic rock drilling device comprises a control stand, a support frame, a power device, a movable carrier and rock drilling equipment, wherein the support frame is arranged on the carrier; the power device, the control stand and the rock drilling equipment are arranged on the support frame; the power device is connected with the rock drilling equipment through a lead; the control stand is connected with the power device and the rock drilling equipment through leads respectively; the support frame is a square frame body; the support frame body is provided with at least one group of platforms capable of extending and contracting towards both sides; the rock drilling equipment comprises one or more groups of mechanical arms and drill bits arranged on the mechanical arms; one end of each mechanical arm is connected to the frame body; and the other end of each mechanical arm is provided with a drill bit. The automatic rock drilling device has the advantages of high rock drilling efficiency, use safety, saving in time and construction cost, and the like.

Description

technical field [0001] The invention relates to the field of tunnel rock drilling equipment, in particular to an automatic rock drilling device for special tunnel excavation that is safe, efficient, time-saving and construction cost-saving. Background technique [0002] At present, the tunnel rock drill mainly uses a movable carrier and an arm directly installed on the carrier for excavation. Generally speaking, the movable carrier used here is a small vehicle. In order to ensure balance, generally only a small amount of arm is loaded. hand, and the size of the arm and hand is also small. Such tunnel rock drilling equipment has long drilling time and slow rock drilling efficiency during the rock drilling process. If danger occurs during the rock drilling process (generally The collapse of the tunnel ahead caused most of the vehicles to be buried), and the personnel operating the arm in the vehicle are likely to be buried, and the survival rate is low. It is necessary to fol...

Generally speaking, the movable carrier used here is a small vehicle. In order to ensure balance, generally only a small amount of arm is loaded. hand, and the size of the arm and hand is also small. Such tunnel rock drilling equipment has long drilling time and slow rock drilling efficiency during the rock drilling process. If danger occurs during the rock drilling process (generally The collapse of the tunnel ahead caused most of the vehicles to be buried), and the personnel operating the arm in the vehicle are likely to be buried, and the survival rate is low. It is necessary to follow the rear of the vehicle, which will cause great harm to the body and safety of the researchers in the rock formation
