Title:
ROCK DRILLING, SWELLING AND CHISELLING COMBINED MACHINE BASED ON HIGH-PRESSURE FOAM MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/099262
Kind Code:
A1
Abstract:
Provided is a rock drilling, swelling and chiselling combined machine based on a high-pressure foam medium, which comprises: a mechanical device of the rock drilling, swelling and chiselling combined machine, a high-pressure foam generating and conveying system, and a hole-sealing device. The rock drilling, swelling and chiselling combined machine comprises a power device (1), an impact piston (21), an electric motor (17), a transmission gear group, an impact rotation drill bit (8), a drill rod (3), a drill hole sealing device (7), a high-pressure foam conveying chamber (4), the high-pressure foam generating and conveying system etc. The high-pressure foam generating and conveying system comprises a liquid pump (10), a gas pump (9), a liquid-gas mixer (11) and a supercharger (12), and can adjust a liquid-gas mixing ratio and convey pressure according to operating conditions of different rock hardnesses. The rock drilling, swelling and chiselling combined machine effectively solves the problems that the existing drilling-in rock drill has a low efficiency in the operations of drilling, sealing and swelling, and the process is complicated. The sealing and swelling errors caused by the drilling and sealing operations of the drilling-in rock drill on a working face are prevented, a continuous operation of the rock drilling, swelling and chiselling combined machine is achieved, and the operation efficiency of the drilling-in rock drill is effectively improved.
