Description

Movable three-arm top support anchor rod and anchor cable construction drilling rig

technical field

The invention relates to coal mine underground excavation equipment, which is suitable for large, medium and small coal mines, and is a roof bolt and anchor cable construction machine required for continuous mining, continuous excavation, and fully mechanized excavation construction of various roadways.

Background technique

At present, the main methods of roadway excavation in various coal mines are continuous mining, continuous excavation, and fully mechanized excavation. The support methods are bolts, anchor cables, joists, and anchor nets. Drilling rig or crawler type liftable roof bolt and anchor cable construction drilling rig, such as Chinese Patent No.: 200720102731.2 disclosed crawler type liftable roof anchor bolt and cable construction drilling rig, there are two drilling rig devices, one advance support, crawler type The traveling mechanism is advanced support; the traveling mechanism is driven by a hydraulic motor, and the drilling rig platform is installed on the frame of the traveling mechanism; a coal pushing shovel is installed at the front of the crawler walking part of the drilling rig platform; the front end of the platform is equipped with a Hydraulic cylinder type advance support, one side of the advance support is equipped with a hydraulic drilling rig for the construction of roof anchor rod and anchor cable; Installed on the double column, the hydraulic drilling rig rotates 30 degrees to the left or right; the hydraulic drilling rig used to help the construction of anchor rods and cables is installed on the middle side of the drilling rig platform, or to the left, or to the right, and the hydraulic drilling rig is to the left Or rotate 90 degrees to the right, the rig platform is provided with a slideway arranged front and back, the column of the hydraulic drilling rig is located on the slideway, and the oil cylinder installed on the rig platform pushes the rig to move back and forth as a whole.

Hand-held pneumatic drills are used for the construction of anchor bolts and cables. This method of construction of anchor bolts and cables has the following problems:

1. The excavation section of the roadway is small: the excavation section is generally about 15M ² , and when the height of the roadway exceeds 2 meters, scaffolding must be set up to carry out the construction of the roof bolt and anchor cable.

2. Non-mechanized operations. The construction of mine roof bolts and cables using continuous mining and continuous excavation technology has basically realized mechanization. All the excavation processes of bolt and anchor cable construction are carried out by 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. Because the construction of the anchor bolts and cables mainly depends on manpower, the construction quality of the anchor bolts and cables cannot fundamentally be guaranteed.

3. The construction speed is slow, and it takes a lot of time to build and dismantle scaffolding when the construction section exceeds 2 meters.

4. Low efficiency: Due to the large number of drilling holes and the large number of construction workers, the operation efficiency is low.

5. Low safety factor: construction workers work alternately at high altitude, and the working safety environment is poor.

The deficiencies and problems that exist for the crawler-type liftable roof bolt and anchor cable construction drilling rig are as follows:

1. Two crawler-type liftable roof anchor rod and cable drilling rigs must be used in a complete set, that is, the hydraulic drilling rig used for the construction of the anchor rod and anchor cable should be installed on the left and right sides of the drilling rig platform. The direction of rotation of hydraulic drilling rigs is different. When the roadway is excavated, two crawler-type drilling rigs with liftable roof, side and side anchor rods and cables are arranged in sequence on both sides of the roadway for construction.

2. It takes a long time to advance and retreat the machine, and the auxiliary workload is large. During excavation construction, two drilling rigs are required to drive into or withdraw from the excavation face in turn, plus the dragging of cables, the time is long and the auxiliary workload is large.

3. Poor adaptability to complex geological conditions. In case of complex geological conditions such as faults, high gas areas, and high water content areas, the drilling rig cannot complete the construction of gas prediction holes, gas discharge holes, geological detection holes, and vibration blastholes.

4. The construction of the roof anchor rod and anchor cable cannot reach zero lag, which is unfavorable for the control of the road side.

5. The workload of the roof bolt and anchor cable construction does not match, the workload of the top drill is large, and the workload of the auxiliary drill is small, which affects the support time and causes personnel to stop working.

6. The construction workers work alternately at high altitude, and the working safety environment is poor.

7. Many people are employed, and two drilling rigs need to be equipped with 8 people.

The movable three-arm roof anchor rod and anchor cable construction drilling rig can use the mechanical arm to drill holes perpendicular to the working face, realizing the mechanized construction of gas prediction holes, gas discharge holes, and geological detection holes, effectively reducing the auxiliary workload , ancillary working hours, and ancillary staff.

5. The movable three-arm roof anchor rod and cable construction drilling rig adopts the single-machine three-arm support technology. One roadway only needs to be equipped with one drilling rig, which is less equipped than the crawler-type liftable roof anchor rod and anchor cable construction drilling rig. One machine effectively reduces the time for advancing and retreating machines during the support process and the maintenance workload during the maintenance process, and reduces the cost of mechanical and electrical maintenance.

6. There are 4 fixed-post personnel in the support process of the movable three-arm top support anchor rod and anchor cable construction drilling rig, which is reduced by half compared with the 8 fixed-post personnel of the crawler-type liftable top support support anchor rod and cable construction drilling rig. The purpose of increasing efficiency, high yield and high efficiency.

7. Roof bolts and cables can be constructed at the same time, and the roof bolts and cables can reach zero lag, which is very beneficial to the excavation of soft coal seams. It can effectively control the roof and prevent the occurrence of roof accidents, with a high safety factor.

8. It is very suitable for comprehensive excavation and single lane excavation. When excavating a single roadway, the movable three-arm roof anchor rod and anchor cable construction drilling rig is parked on one side of the roadway. The principle is not to affect the coal cutting of the fully mechanized excavator; Next, the mobile three-arm top support anchor rod and anchor cable construction drilling rig enters under the empty roof for support.

9. The adoption of the movable three-arm roof anchor rod and anchor cable construction drilling rig can change the existing continuous mining, continuous excavation double-lane or three-lane excavation technology, and the combination of continuous miner or high-power roadheader and bolter The inverted operation site is changed to alternate advancing and retreating machine operation, which reduces the impact time and improves the excavation speed.

10. Good environmental protection effect. The hydraulic bolt drilling rig adopts wet drilling, which can effectively reduce the harm of dust to the workers. At the same time, the long-distance operation of the drilling rig can make the workers avoid the drilling water, effectively improve the working environment of the workers, and reduce the occurrence of silicosis and rheumatism. Protect the physical and mental health of employees.

In a word, the movable three-arm roof bolt and anchor cable construction drilling rig of the present invention has improved the technical level of coal mine underground excavation, especially for the realization of continuous mining, continuous excavation, and comprehensive excavation of large, medium and small coal mines. Mechanization, providing a complete set of technical equipment, creates the most basic conditions for large, medium and small coal mines to achieve safe production, and at the same time greatly improves the resource recovery rate, and can achieve greater output with the smallest input. Comprehensive, systematic and thorough It solves the serious problems existing in the existing tunneling support equipment.
