Problems solved by technology
[0005] 2. The construction of roof anchor bolts and cables is non-mechanized and labor-intensive
The mine roof bolt and cable construction using the continuous mining and continuous excavation technology has basically realized mechanization, and the mine roof bolt and cable construction using the fully mechanized excavation technology is still a manual operation of a single drilling rig, while the auxiliary bolt and cable construction is all The excavation process is all carried out with hand-held pneumatic drills. The thrust of the drilling comes from the human arm and arm, and the labor intensity of the workers is high.
Since the construction of the anchor bolts and cables mainly relies on manpower, the construction quality of the anchor bolts and cables cannot be guaranteed fundamentally.
[0006] 3. Slow construction speed
It takes a lot of time to erect and dismantle scaffolding when the construction section exceeds 2 meters
[0007] 4. Low efficiency
Due to the large number of drilling holes and the large number of construction workers, the operation efficiency is low
[0008] 5. Low safety factor
The construction workers work alternately at high altitude, and the working safety environment is poor
[0009] 6. Long impact time
The existing continuous mining, continuous excavation double- or three-lane tunneling technology consists of a continuous mining machine or a high-power roadheader and a crawler bolter that are large in size and cannot work in the same tunnel at the same time. It is necessary to reverse the tunnel to realize excavation. Branch parallel operation, while the distance of the reverse roadway is from 20 meters to 110 meters, the impact time is long, and the tunneling speed has a great influence
[0010] 7. Too much invalid footage
The distance between cross-cuts should neither be too long nor too short; if the distance between cross-cuts is too long, the distance between continuous mining machines or high-power roadheaders and crawler bolters will be increased, and the impact time will be prolonged; if the distance between cross-cuts is too short, construction The increase in the number of Hengchuan will increase a lot of invalid footage

The invention provides a crawler elevator head supporting anchor shank and anchor cable constructing borer. The invention is characterized in that a coal propelling shovel board is arranged on the front part of the stepping part of the track; a constructing hydraulic borer for heading the anchor shank, and the anchor cable is arranged on the front part of the borer platform, the hydraulic borer can turn left or right for 30 degrees; a constructing hydraulic borer for supporting the anchor shank, and the anchor cable is arranged on one side of the middle part of the borer platform, and the hydraulic borer can turn left or right for 90 degrees. The invention adopts the single laneway quick drivage technique. The mechanical equipment used by the invention includes a comprehensive digger, twosets of crawler elevator head supporting anchor shank and anchor cable constructing borers, a scraper board transporter, and a belt conveyer. The technological process is that the comprehensive digger cut the coal, load the coal, and convey the coal, then withdraws under a permanent shoring - the crawler elevator head supporting anchor shank and anchor cable constructing borer enters into the task spot, and heads or supports the anchor shank and anchor cable to shore, and then withdraws under a permanent shoring, the comprehensive digger enters into the task spot, thereby the invention can reduce the labor intensity, can improve the drivage speed, and can create a safe operation circumstance.
Description
technical field [0001] The invention belongs to the underground tunneling technology of coal mines, and is a single-lane rapid excavation technology applicable to anchor net support roadways in large, medium and small coal mines. Background technique [0002] At present, the main methods of roadway excavation in various coal mines are continuous mining, continuous excavation, and fully mechanized excavation. Body drilling rig or crawler drilling rig, such as the mobile walking bolter disclosed in Chinese Patent No. 200420091861.7, has two drilling rig devices, two advanced supports, crawler type traveling mechanism, and the overall horizontal movement slideway and platform of the drilling rig device; The traveling mechanism is driven by a hydraulic motor, and the bolter platform is installed on the frame of the traveling mechanism; two hydraulic cylinder-type advanced supports are installed on both sides of the front end of the platform, and two gantry drilling rig devices a...
