Description

Technical Field

[0001] The invention relates to the technical field of drilling, in particular to a fast excavation drilling device for coal mining. Background Art

[0002] Coal mine drilling plays an important role in improving the mine's ability to resist and prevent disasters. Natural disasters are a major challenge to coal mine safety, and coal mine drilling technology, especially underground drilling, has made many attempts and explorations in disaster prevention and resistance, and has accumulated useful experience. Through underground drilling, the safety performance of mines can be effectively improved, and the lives of miners can be guaranteed, thus making a significant contribution to mine safety production.

[0003] However, in the current coal mine drilling construction process, in order to meet the drilling depth requirements, it is necessary to add drill rods to extend the length of the drill rods. For the addition of drill rods, the traditional operation method is to manually connect the drill rod to be added with the working drill rod to perform the rod addition operation. This manual operation method has high labor intensity, low work efficiency, and certain safety hazards. Alternatively, a manipulator is used to grab the drill rod to be added from the drill rod storage rack, and after it is aligned with the working drill rod, the drill rod to be added is clamped or screwed into one end of the working drill rod to complete the addition of the drill rod. The manipulator is used as a drill rod in this type of drilling operation. The key mechanism of the device needs to complete a series of operations such as grabbing, swinging, and releasing the drill rod according to a given procedure. Therefore, the structural design and movement process of the manipulator are usually complicated, which leads to a complex overall equipment structure of the drilling operation device, high manufacturing cost, and complex operation process. In addition, the manipulator is prone to the risk of the drill rod falling off during the grabbing process, causing damage to the drill rod and even injuring the staff. The manipulator has a large error when grabbing the drill rod, and cannot achieve rapid and accurate docking of the drill rod, thereby delaying the time of excavation drilling. For this reason, we propose a rapid excavation drilling equipment for coal mining. Summary of the invention

[0041] The rotating jaw 8 is arranged on the longitudinal moving mechanism 7, and the drill rod is clamped and screwed in by the rotating jaw 8, so that the drill rod is connected to the rotary head.

[0042] See also Figure 2-3 The feeding control mechanism 5 includes a mounting plate 51, a first return spring 55 is arranged between the mounting plate 51 and the placing plate 4, the mounting plate 51 is arranged on the placing plate 4 through the first return spring 55, a boss 1 41 and a boss 2 42 are arranged on the placing plate 4, the boss 2 42 is located on one side of the boss 1 41, a first lifting plate 52 and a second lifting plate 53 are arranged on both sides of the mounting plate 51, the first lifting plate 52 and the second lifting plate 53 are slidably arranged on the placing plate 4, the first lifting plate 52 and the second lifting plate 53 are respectively located on both sides of the boss 1 41, and an inclined block 54 is arranged on the lower surface of the mounting plate 51. The boss 1 41 and the boss 2 42 are arranged to cooperate, the boss 1 41 can isolate the drill rod at the rear end to prevent it from rolling down naturally, and the boss 2 42 allows the drill rod to be isolated between the boss 1 41 and the boss 2 42, so that when the first lifting plate 52 and the second lifting plate 53 are lifted up, the drill rod behind the boss 1 41 and the boss 2 42 can pass over the boss 1 41 and the boss 2 42 at the same time, and the second lifting plate 53 is set as a curved surface structure, so that when the second lifting plate 53 is lifted up, the second lifting plate 53 can isolate the drill rod that passes over the boss 1 41 to avoid interference between the drill rod and the drill rod that is about to pass over the boss 2 42.

[0043] See also Figure 4-7The transverse movement mechanism 6 includes a transverse movement motor 61, which is arranged on the drilling rig body 1. A transverse screw 611 is arranged at the output end of the transverse movement motor 61. A transverse movement track 62 is arranged on the drilling rig body 1.

[0044] See also Figure 7-8 The clamping mechanism 9 includes a mounting seat 91, which is arranged at both ends of the transverse seat 63, and a second return spring 95 is arranged on the mounting seat 91. The mounting seat 91 is provided with a movable seat 92 through the second return spring 95. A clamping seat 93 is slidably arranged on the mounting seat 91, and the clamping seat 93 is arranged on both sides of the movable seat 92. A connecting rod 94 is arranged between the movable seat 92 and the clamping seat 93, and a long clamping plate 931 is arranged on one of the clamping seats 93, and a short clamping plate 932 is arranged on the other clamping seat 93. When the drill rod comes between the clamping seats 93, it is pressed by the movable seat 92, so that the movable seat 92 descends, and the movable seat 92 moves the clamping seat 93 inwardly through the connecting rod 94, so as to clamp the drill rod. In this way, after the drill rod is clamped, the drill rod is in a more stable state during transportation to avoid accidental falling. At the same time, in the process of separating the drill rod, the clamped drill rod can be successfully separated from the rotating clamp 8.

[0045] See also Figure 9-11 The support member 11 includes a base plate 111, support frames 112 are arranged at both ends of the base plate 111, the base plate 111 is slidably arranged on the drilling rig body 1 through the support frames 112, the support frames 112 are slidably arranged on the drilling rig body 1, a groove 1121 is provided at the upper end of the support frame 112, a first slope 1122 is provided on one side of the support frame 112, connecting plates 113 are arranged on both sides of the lower surface of the base plate 111, and a Z-shaped groove 1131 is provided on the connecting plate 113. Through the Z-shaped groove 1131, only the Z-shaped groove 113 of the cross bar 101 is provided. When the inclined section 1 moves, the base plate 111 can be raised. In this way, when the support frame 112 is raised or lowered to an appropriate height, the rotating clamp 8 can still continue to move a certain distance, and the first slope 1122 is set, and the drill rod between the clamping seats 93 moves toward the support frame 112, and the drill rod comes to the first slope 1122 and continues to move with the traverse seat 63. At this time, the drill rod walks on the first slope 1122 until the height of the drill rod exceeds the short clamping plate 932, and then the drill rod is pushed by the long clamping plate 931 to come into the groove 1121.

[0046] See also Figure 3 The longitudinal moving mechanism 7 includes a longitudinal moving motor 71, which is arranged on the drilling rig body 1. A longitudinal screw 711 is arranged at the output end of the longitudinal moving motor 71. A longitudinal moving track 72 is arranged on the drilling rig body 1. A longitudinal moving seat 73 is slidably arranged on the longitudinal moving track 72. The longitudinal moving seat 73 is connected to the longitudinal screw 711 through a threaded connection. A connecting seat 81 is arranged on the longitudinal moving seat 73. The rotating clamp 8 is connected to the longitudinal moving seat 73 through the connecting seat 81.

[0047] See also Figure 9-11 A pushing rod 10 is provided on the lower surface of the connecting seat 81, and a cross bar 101 is provided on the pushing rod 10. The cross bar 101 is slidably set in the Z-shaped groove 1131. The pushing rod 10 pushes the cross bar 101 to move in the Z-shaped groove 1131, so that the base plate 111 drives the support frame 112 to descend, so as to avoid friction between the drill rod and the support frame 112 when the rotating jaw 8 rotates, thereby preventing the support frame 112 and the drill rod from being damaged.

[0048] See also Figure 9-10 A rolling plate 12 is obliquely arranged on the drilling rig body 1, and a support plate 121 is arranged on one side of the rolling plate 12. The rolling plate 12 is connected to the drilling rig body 1 through the support plate 121. A second slope 1211 is provided on the side of the support plate 121 close to the placement plate 4. The second slope 1211 also allows the height of the drill rod clamped by the clamping seat 93 to be increased when the drill rod walks on its surface.

[0049] See also Figure 2-3 A crossbeam 31 is provided on the mounting frame 3, and the placement plate 4 is connected to the mounting frame 3 through the crossbeam 31, and the placement plate 4 is tiltedly arranged on the mounting frame 3.

[0050] When in use, by placing the drill rod on the placement plate 4, since the placement plate 4 is tilted and arranged on the mounting frame 3, the drill rod naturally rolls down and is intercepted by the boss 1 41, and the lateral movement motor 61 is started to make the lateral movement seat 63 move toward the inclined block 54, and the mounting seat 91 moves below the placement plate 4 following the lateral movement seat 63, when the roller 632 is squeezed by the inclined block 54 and the inclined block 54 drives the mounting plate 51 to rise, the first lifting plate 52 and the second lifting plate 53 rise synchronously at this time, so that the drill rod between the boss 1 41 and the boss 2 42 is lifted up by the second lifting plate 53 and falls between the clamping seats 93, and the drill rod lifted up by the first lifting plate 52 passes over the boss 1 41 and comes to the boss 1 4 1 and the boss 2 42, when the drill rod comes between the clamping seat 93, it is pressed by the movable seat 92, so that the movable seat 92 descends, and the movable seat 92 moves the clamping seat 93 inward through the connecting rod 94 to clamp the drill rod, and then the lateral movement motor 61 rotates in the opposite direction, so that the drill rod between the clamping seats 93 moves closer to the support frame 112, when the drill rod comes to the first slope 1122 and as the lateral movement seat 63 continues to move, the drill rod walks on the first slope 1122 until the height of the drill rod exceeds the short clamping plate 932, at which time the drill rod is pushed into the groove 1121 by the long clamping plate 931, and then the lateral movement seat 63 switches the rotation direction again to pick up the next drill rod;

[0051] At this time, the longitudinal moving motor 71 operates to make the rotating jaws 8 approach the drill rod along the longitudinal moving track 72 until the drill rod is between the rotating jaws 8, and the rotating jaws 8 are started to clamp the drill rod. As the rotating jaws 8 continue to move, the jacking rod 10 pushes the cross bar 101 to move in the Z-shaped groove 1131, so that the base plate 111 drives the support frame 112 to descend, so as to avoid the friction between the drill rod and the support frame 112 when the rotating jaws 8 rotate, resulting in damage to the support frame 112 and the drill rod. When the drill rod and the drill bit are connected by threads, the longitudinal moving motor 71 reverses to reset the rotating jaws 8, and the drill rod continues to drill along with the drill bit through the drilling rig body 1, and when the mounting seat 91 receives the next drill rod, it continues the previous step to dock with the previous drill rod.

[0052] When the drilling work is completed, the drill rod is withdrawn. At this time, the mounting seat 91 is moved to the bottom of the drill rod through the horizontal movement motor 61, and the rotating clamp 8 is docked with the drill rod through the longitudinal movement motor 71, and the drill rod is clamped and rotated while retreating backwards, so that the drill rods are separated. When the drill rods are successfully separated, the rotating clamp 8 releases the clamping of the drill rod, so that the drill rod falls on the mounting seat 91, and the drill rod is clamped by the clamping seat 93. As the rotating clamp 8 continues to move backward, the drill rod is separated from the rotating clamp 8, and then the mounting seat 91 is moved toward the rolling plate 12 through the horizontal movement motor 61. When the drill rod walks on the second slope 1211 and rises over the short clamp 932, the drill rod comes to the rolling plate 12, so that the drill rod is collected on the rolling plate 12, which makes it convenient for construction personnel to check the drill rod for the next construction.
