Rock-socketed drilling machine

Abstract

The invention discloses a rock-socketed drilling machine. The rock-socketed drilling machine comprises a door frame, a sliding frame which is transversely arranged on the door frame and can slide up and down on the door frame, a chassis which is mounted on the door frame and is positioned below the sliding frame, lifting oil cylinders which are mounted between the chassis and the sliding frame andare used for driving the sliding frame to move up and down, a driving part which is fixedly mounted on the sliding frame, a drilling rod which is in transmission connection with the driving part andis arranged on a base in a penetrating manner, and a cutter disc which is fixed to the lower end part of the drilling rod; the chassis comprises guide rails; the rock-socketed drilling machine also comprises a sealing flat machine assembly which is connected with the guide rails in a sliding manner; a clamp which is used for clamping the drilling rod when the drilling rod and the cutter disc are lifted is arranged on the rock-socketed drilling machine. The driving part is driven by adopting a variable frequency motor; the speed change range is wide; the output energy efficiency is high; the output torque is large; the variable frequency motor can rotate forward and backward, can perform speed changing in a stepless manner, and can also bear very large axial load. The drilling rod can be disassembled and assembled quickly by the advanced clamp and the advanced sealing flat machine system. A pulp discharging principle is a gas lift reverse circulation principle.

Description

technical field [0001] The invention belongs to the field of shield equipment, in particular to a rock-socketed drilling machine. Background technique [0002] Existing rock-socketed drilling rigs have the following disadvantages: the use of hydraulic motor drives, low output energy efficiency, small torque, unable to achieve pressurized drilling, and low rock layer excavation efficiency; There is only one for each, and full-section coverage cannot be achieved; in rock-socketed drilling, traditional engineering tools adopt the principle of rolling and grinding rock breaking, and the rock breaking efficiency is low; the tool box and tool connections are prone to loosening; the tool wears fast, It is necessary to change the cutter frequently; there is a gap between the cutter and the cutter box, the sand will flow to the back of the cutter head, and the mud backflow does not pass between the cutter head and the cutting surface, resulting in a short circuit of the mud and aff...
