Description

Technical Field

[0001] The invention relates to the technical field of coal mine drilling rigs, and in particular to an airborne anchor drilling rig for coal mines. Background Art

[0002] Anchor drill for coal mine is a drilling tool used in anchor support work in coal mine tunnels, also known as anchor drilling rig. Its main function is to drill holes in coal mine tunnels to install anchors to enhance the stability of the tunnels. This drilling rig has significant advantages in improving support effects, reducing support costs, speeding up tunneling, reducing auxiliary transportation volume, reducing labor intensity, and improving tunnel section utilization. Anchor drilling rig is a key equipment for anchor support, which affects the quality of anchor support, including the orientation, depth, and accuracy of the aperture of the anchor hole, the quality of anchor installation, and the operator's work safety.

[0003] When using an airborne anchor drill for coal mines, first determine the location and range of the anchor reinforcement, select the appropriate anchor drill model and specifications according to the requirements, then fix the drill on the work platform, start the drill and start it working. The operator can control the speed, pressure, drill bit diameter and other parameters of the drill through a remote control or control system to ensure the quality and accuracy of drilling. When the drill reaches the predetermined depth, stop the drill and install the anchor in place.

[0004] If the coal mine airborne anchor drilling rig does not adjust the drilling position properly when drilling, the drilling direction of the drill bit may be tilted towards the inner wall of the mine. Since the drill bit is tilted towards the inner wall of the mine, the axis of the drill hole will deviate from the designed drilling position, which may cause instability in subsequent construction processes. At the same time, it will affect the normal arrangement of the anchor rod, reduce the overall work efficiency, and may cause problems with the length and angle of the anchor rod, which will greatly affect the safety of the mine, cause the mine wall to collapse, and bring safety hazards to the workers. Summary of the invention

[0005] The present invention proposes an airborne anchor drilling rig for coal mines, which solves the problem in the prior art that during the drilling process, due to the drilling position not being adjusted properly, the drilling direction of the drill bit is tilted towards the inner wall of the mine, causing the axis of the drill hole to deviate from the designed drilling position, resulting in instability during the subsequent installation of the anchor, affecting the safety in the mine.

[0059] 1. In the present invention, when the hydraulic cylinder drives the lifting frame to move through the sliding frame, the lifting frame drives the square rod to rotate in the mounting frame. Since two square rods are provided and form a stable structure with the sliding frame, as the lifting frame moves, the two square rods slide on the mounting frame at the same time as the lifting frame moves, thereby improving the stability of the lifting frame and facilitating the determination of the anchor rod reinforcement position.

When the positioning frame rotates through a certain angle until the position of the drill body is adjusted, the second motor can be turned off and locked. At this time, the position between the worm wheel and the worm is relatively fixed, and the relative position of the positioning frame and the swing frame is fixed, which is convenient for adapting to the inner wall of the mine in different situations, making the angle between the inner wall of the mine and the drill body more reasonable, reducing the possibility of damage to the drill body, and improving the quality of drilling.

[0061] 3. In the present invention, when the feed frame moves to the working position, the box is moved to the position of the inner wall of the mine, and the second electric cylinder is started. The second electric cylinder drives the stabilizing plate to move until the stabilizing plate contacts the inner wall of the mine, thereby maintaining the stability of the drilling and improving the drilling quality and work efficiency.

[0062] 4. In the present invention, by setting the displacement assembly and the lifting assembly, the drill body can be quickly and stably moved to the working position, and by setting the swing assembly and the feed assembly, the angular position between the drill body and the inner wall of the mine can be further adjusted, thereby reducing the possibility of the axis of the drill hole deviating from the designed drilling position due to the inclination of the drilling direction of the drill bit and the inner wall of the mine, improving the quality of the drill hole, reducing the occurrence of accidents such as mine wall collapse due to deviations in the size and position of the anchor hole, and improving the safety of construction.

[0077] Specifically, when using the airborne anchor drilling rig for coal mines, first determine the position and range of the anchor reinforcement, select the appropriate anchor drilling rig model and specifications according to the requirements, then start the self-propelled frame 2, and after the self-propelled frame 2 moves to the working position, close and lock the self-propelled frame 2, and then start the hydraulic cylinder 5, the hydraulic cylinder 5 drives the lifting frame 4 to move along the axial direction of the hydraulic cylinder 5, and through the setting of the sliding part, the movement of the lifting assembly is more stable, until the lifting frame 4 is moved to the working position, and then close and lock the hydraulic cylinder 5 to fix the position of the lifting frame 4, and then start the lifting assembly to drive the feeding assembly to move to the working position, at this time start the swing assembly and the feeding assembly, through the cooperation of the two, the stabilizing assembly is moved to the position of the anchor reinforcement, start the stabilizing assembly to ensure the overall stability of the equipment during the processing, and then start the drilling rig body 1 to drill the anchor reinforcement position. After the drilling is completed, retract the drilling rig body 1, and install the processed anchor into the hole according to the design requirements and the drilling position.

[0078] The above, such as Figure 3 , Figure 4 As shown, the sliding part includes a mounting frame 7 and a square rod 8. Two mounting frames 7 are symmetrically and fixedly mounted on the top of the displacement frame 3. Square rods 8 are slidably mounted on the two mounting frames 7.

[0079] Specifically, when the hydraulic cylinder 5 drives the lifting frame 4 to move through the sliding frame 6, the lifting frame 4 drives the square rod 8 to rotate in the mounting frame 7. Since two square rods 8 are provided, as the lifting frame 4 moves, the two square rods 8 slide on the mounting frame 7 at the same time as the lifting frame 4 moves, thereby improving the stability of the lifting frame 4 and facilitating the determination of the anchor reinforcement position.

The stabilizing rod 12 slides with the moving frame 9, and the driving unit is installed on the lifting frame 4 to drive the transmission screw 10 to rotate.

[0081] Specifically, after the lifting frame 4 is moved to the working position, it is also necessary to adjust the height of the drilling rig body 1, start the driving unit and drive the two transmission screws 10 to rotate at the same time, and the two transmission screws 10 drive the moving frame 9 to move at the same time through the transmission nut 11 until the moving frame 9 is driven to the working position. During the movement of the moving frame 9, the movement of the moving frame 9 is made smoother by the setting of the stabilizing rod 12. The driving unit can be closed until the moving frame 9 drives the drilling rig body 1 to the working position, and the relative position between the moving frame 9 and the lifting frame 4 is fixed.

[0087] Specifically, after adjusting the position of the drill body 1 by the mobile frame 9, it is necessary to adjust the angle of the drill body 1 according to the specific conditions of the inner wall of the mine.

The second electric cylinder 33 drives the stabilizing plate 34 to move until the stabilizing plate 34 contacts the inner wall of the mine, thereby maintaining the stability of the drilling. After the drilling is completed, the second electric cylinder 33 can be retracted.

[0094] In summary, when using the airborne anchor drill for coal mines, first determine the position and range of anchor reinforcement, select the appropriate anchor drill model and specification according to the requirements, then start the self-propelled frame 2, and after the self-propelled frame 2 moves to the working position, close and lock the self-propelled frame 2, and then start the hydraulic cylinder 5, the hydraulic cylinder 5 drives the lifting frame 4 to move along the axis direction of the hydraulic cylinder 5, and at the same time, the lifting frame 4 drives the square rod 8 to rotate in the mounting frame 7. Since two square rods 8 are provided, as the lifting frame 4 moves, the two square rods 8 move with the lifting frame 4 at the same time. The lifting frame 4 slides on the mounting frame 7 due to its movement, thereby improving the stability of the lifting frame 4 and facilitating the determination of the anchor rod reinforcement position, until the lifting frame 4 is moved to the working position, and then the hydraulic cylinder 5 is closed and locked to fix the position of the lifting frame 4, and then the first electric cylinder 16 is started, and the first electric cylinder 16 drives the base frame 17 to move until the base frame 17 contacts the ground. When the position of the lifting frame 4 is fixed through the cooperation of the base frame 17 and the first electric cylinder 16, the first electric cylinder 16 can be closed and locked, thereby improving the stability of the mobile frame 9 during the movement.

[0095] After the lifting frame 4 is moved to the working position, it is also necessary to adjust the height of the drilling rig body 1. At this time, the first motor 14 is started, and the first motor 14 drives the driving gear 15 to rotate. The driving gear 15 also drives the two driven gears 13 to rotate, thereby simultaneously driving the two driving screws 10 to rotate through the two driven gears 13, and the two driving screws 10 simultaneously drive the moving frame 9 to move through the driving nuts 11 until the moving frame 9 is driven to the working position. During the movement of the moving frame 9, the stabilizing bar 12 is set to make the movement of the moving frame 9 more stable, until the moving frame 9 drives the drilling rig body 1 to the working position, the first motor 14 can be turned off, and the relative position between the moving frame 9 and the lifting frame 4 can be fixed.

[0096] After adjusting the position of the drill body 1 by the mobile frame 9, it is necessary to adjust the angle of the drill body 1 according to the specific conditions of the inner wall of the mine.

At this time, the position between the worm wheel 19 and the worm 20 is relatively fixed, and the relative position of the positioning frame 22 and the swing frame 18 is fixed. After the drilling rig body 1 is positioned, the fourth motor 30 is started, and the fourth motor 30 drives the adjusting gear 31 to rotate. The adjusting gear 31 drives the feed frame 23 to slide in the positioning frame 22 through the setting of the rack 29 until the feed frame 23 is moved to the working position. The fourth motor 30 can be closed and locked. At this time, the box body 32 is moved to the position of the inner wall of the mine. At this time, the second electric cylinder 33 is started, and the second electric cylinder 33 drives the stabilizing plate 34 to move until the stabilizing plate 34 contacts the inner wall of the mine, thereby maintaining the stability of the drilling hole and fixing the position between the positioning frame 22 and the feed frame 23.

[0097] At this time, the third motor 25 is started, and the third motor 25 drives the second screw 24 to rotate, and the second screw 24 drives the second nut 26 to move, and the second nut 26 drives the pushing frame 27 to move, thereby driving the drilling rig body 1 to move through the pushing frame 27. After the drilling rig body 1 is moved to the working position, the third motor 25 is turned off and locked, and the relative positions of the pushing frame 27 and the feed frame 23 are fixed, and the drilling rig body 1 can be started to drill the anchor position.
