Vehicle-mounted folding retractable type down-the-hole drill

Abstract

The invention discloses a vehicle-mounted folding retractable type down-the-hole drill. The Vehicle-mounted folding retractable type down-the-hole drill comprises a vehicle body, a folding arm mountedon the vehicle body, a high-wind-pressure air compressor mounted on the vehicle body, a hydraulic main pump device, a traction engine and a vehicle-mounted host. The front end of the folding arm is provided with a plurality of sets of fully-automatic drill head systems. The fully-automatic drill head systems and the front end of the folding arm are connected through two hydraulic worm deceleration slewing bearings capable of rotating by 360 degrees. The vehicle-mounted host is internally provided with a PLC system. The PLC system controls opening and closing of the high-wind-pressure air compressor and controls the drill head systems and the folding arm to automatically find hole positions, automatically adjust angles, automatically drill and automatically change drill pipes. According tothe vehicle-mounted folding retractable type down-the-hole drill, the down-the-hole drill is moved through the vehicle body and convenient to move and convenient to operate and use by workers, the full automatic drill head system working area in enlarged, and the moving frequency of the down-the-hole drill is decreased, so that the working efficiency is improved.

Description

technical field [0001] The invention relates to down-the-hole drilling equipment for drilling soil layers or rocks, in particular to a vehicle-mounted foldable and telescopic down-the-hole drilling rig. Background technique [0002] Down-the-hole drilling rigs are common equipment for deep-hole rock drilling in mountain mining, hydropower station construction, railway, highway and port construction soil and rock mining. At present, the down-the-hole drilling rigs used include tripod-shaped down-the-hole drilling rigs and crawler-type down-the-hole drilling rigs. During the blasting operation on the original original mountain, the crawler-type down-the-hole drilling rigs cannot reach the position of the blast hole, and tripod-shaped down-the-hole drilling rigs are required. After manual dismantling, lift up the mountain to the position of the blast hole and then assemble it and adjust the support before drilling. When a blast hole is finished, it must be disassembled and then...

Problems solved by technology

At present, the down-the-hole drilling rigs used include tripod-shaped down-the-hole drilling rigs and crawler-type down-the-hole drilling rigs. During the blasting operation on the original original mountain, the crawler-type down-the-hole drilling rigs cannot reach the position of the blast hole, and tripod-shaped down-the-hole drilling rigs are required. After manual dismantling, lift up the mountain to the position of the blast hole and then assemble it and adjust the support before drilling. When a blast hole is finished, it must be disassembled and then manually lifted to the next blast hole position to reassemble the support and adjust the efficiency. It is extremely low and requires a lot of labor. Only when the mountain is blasted to a relatively flat level by this construction method can the crawler down-the-hole drilling rig enter the site for drilling operations. The crawler down-the-hole drilling rig has high requirements on the terrain and must be flat without any height. Uneven potholes and bumps, so it is necessary to rely on the cooperation of the crushing head and the excavator to renovate the work site

In addition, derrick drilling is currently used to blast reefs and drill holes, which is very expensive and inefficient

[0003] In addition, the crawler down-the-hole drilling rig cannot walk on places with too large a slope, because the center of gravity is too high and cannot be assisted by a bucket like an excavator, so the road to the job site must be very flat, and because the weight is too large, Do not work too close to the air surface to prevent falling off the cliff, otherwise the rationality of the position of the blast hole will be sacrificed, and the walking mechanism adopts crawler type walking, and the crawler belt often falls off when walking and adjusting the working position, that is We often say that the chain is dropped. Once the chain is dropped, the entire equipment cannot work. Reinstalling the track is a very difficult job, which requires the cooperation of cranes and other lifting equipment and takes a lot of time.

[0004] In addition, crawler down-the-hole drilling rigs are basically useless when drilling anchor rods and anchor cables on slopes. At present, manual steel pipe frames are still used, and then the tripod down-the-hole drilling rig is disassembled and lifted up. After finishing a hole, disassemble and reassemble

Therefore, the deep hole blasting and slope bolt and anchor cable construction drilling operations currently required can no longer meet the ever-changing needs.
