Description

Technical Field

[0001] This invention relates to the field of coal mine drilling rig technology, specifically to a split-type fully hydraulic anchor bolt drilling rig. Background Technology

[0002] Currently, secondary reinforcement of the roof and side bolts in fully mechanized mining faces with goaf-side entry is a major task in coal mine construction and maintenance. However, there are many practical problems in carrying out support operations in narrow roadways.

[0003] If the roadway along the goaf is narrow and large machinery cannot enter, the current operation requires operators to use hand-held hydraulic single anchor drilling rigs / pneumatic anchor heads to complete the work. This is not only inefficient and labor-intensive, but also has poor safety. In addition, most drilling rigs do not have the function of automatically loading and unloading drill rods. For workers working in the dark and damp underground, adding and removing drill rods is a time-consuming and laborious task. Improper operation can also cause accidents, which is difficult to meet the needs of the workers. Summary of the Invention

Two sets of drilling mechanisms can drill at any position in the first and second regions respectively, improving drilling efficiency. In addition, through the coordinated use of the drilling mechanism, storage mechanism, and connecting mechanism, the drilling depth can be increased by adding an extension rod when the drilling depth is insufficient, until the drilling requirement is met. When adding an extension rod, the drill rod or extension rod stored inside the borehole will not fall off due to accidental vibration because the clamping part abuts against the inner wall of the borehole. This further enhances the ingenuity of the device design and meets the needs of the workers. Attached Figure Description

[0039] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0040] Example 1

[0041] Please refer to Figures 1-12 As shown, a split-type fully hydraulic anchor bolt drilling rig includes a tracked vehicle 1. A lifting mechanism 2 is installed on the top of the tracked vehicle 1. A fixing mechanism 3 is connected to the lifting mechanism 2. The fixing mechanism 3 is used to clamp the machine body 101. A storage mechanism 4 is provided on the top of the machine body 101. Two sets of connecting frames 102 are fixedly installed on the left side of the machine body 101. A first sliding frame 103 and a second sliding frame 104 are slidably connected in the connecting frame 102. A telescopic mechanism 5 is provided between the connecting frame 102, the first sliding frame 103 and the second sliding frame 104. A drilling mechanism 7 is installed at the end of each of the two sets of second sliding frames 104. A clamping mechanism 6 is provided on both the connecting frame 102 and the second sliding frame 104.

[0042] Example 2

[0043] Please refer to Figure 2 and Figure 3 As shown, the lifting mechanism 2 includes two sets of fixed frames 201 fixedly installed on the top of the tracked vehicle 1. A first lead screw 202 is rotatably connected inside the fixed frame 201. A lifting plate 205 is threadedly connected to the outer wall of the first lead screw 202. The lifting plate 205 is slidably connected to the first guide rod 203. The first guide rod 203 is welded to the inside of the fixed frame 201. A first stepper motor 204 for driving the first lead screw 202 to rotate is provided on the top of the fixed frame 201.

[0044] Those skilled in the art will understand that by synchronously driving the output ends of the two sets of first stepper motors 204 to rotate, the first lead screw 202 is synchronously driven to rotate, causing the lifting plate 205 to move up and down along the outer wall of the first guide rod 203, thereby realizing the change of the fixed mechanism 3 and the machine body 101 as a whole to move up and down.

[0045] Example 3

[0046] Please refer to Figure 2 and Figure 3 As shown, the fixing mechanism 3 includes a fixing block 301, a first threaded rod 302, and a clamping member 305. The fixing block 301 has two sets, both welded to the outside of the lifting plate 205. The first threaded rod 302 is rotatably connected between the two sets of fixing blocks 301. The threads at both ends of the first threaded rod 302 have opposite directions. The clamping member 305 has two sets and is threaded to both ends of the outer wall of the first threaded rod 302. The outer end of the first threaded rod 302 is fixedly connected to the output end of the first servo motor 304. The first servo motor 304 is located outside one set of fixing blocks 301. A first fixing rod 303 is also fixedly installed between the two sets of fixing blocks 301. Both sets of clamping members 305 are slidably connected to the first fixing rod 303. The machine body 101 has a slot 105 adapted to the clamping member 305.

[0047] Those skilled in the art will understand that the output end of the first servo motor 304 drives the first threaded rod 302 to rotate, causing the two sets of clamping members 305 to move closer or further apart. When the two sets of clamping members 305 move closer together, they enter the slots 105 opened on the machine body 101 respectively, thereby fixing the machine body 101. Conversely, the fixing of the machine body 101 is released.

[0048] Example 4

[0049] Please refer to Figure 4 , Figure 5 and Figure 6 As shown, the storage mechanism 4 includes a second lead screw 401 and a second guide rod 402. The second lead screw 401 is rotatably connected to the top of the body 101, and the second guide rod 402 is fixedly connected to the top of the body 101. A movable frame 404 is slidably connected to the second guide rod 402, and the movable frame 404 is threadedly connected to the second lead screw 401. A second stepper motor 403 that drives the second lead screw 401 to rotate is installed on the outside of the body 101. A storage frame 406 is rotatably connected to the inner wall of the movable frame 404. Several sets of extension rods 411 are stored in the storage frame 406. The rotation of the storage frame 406 is driven by a first drive motor 405 provided on the outside of the movable frame 404.

[0050] Please refer to Figure 4 , Figure 5 and Figure 6 As shown, a push plate 410 is also provided inside the storage frame 406. The push plate 410 is threadedly connected to the third lead screw 407. The third lead screw 407 is rotatably connected to the outside of the storage frame 406. A third guide rod 408 is also welded to the outside of the storage frame 406. The push plate 410 and the third guide rod 408 are slidably connected. The outer end of the third lead screw 407 is fixedly connected to the output end of the third stepper motor 409. The third stepper motor 409 is located on the outside of the storage frame 406.

[0051] Those skilled in the art will understand that by rotating the output of the first drive motor 405, the storage frame 406 can be rotated, keeping the storage frame 406 in an inclined state so that the extension rod 411 inside will not fall off; by rotating the output of the second stepper motor 403, the second lead screw 401 is driven to rotate, causing the movable frame 404 to reciprocate back and forth along the outer wall of the second guide rod 402, thereby realizing the reciprocating back and forth movement of the storage frame 406; and by rotating the output of the third stepper motor 409, the third lead screw 407 is driven to rotate, causing the push plate 410 to reciprocate left and right along the outer wall of the third guide rod 408.

[0052] Example 5

[0053] Please refer to Figure 8 As shown, the telescopic mechanism 5 includes a first connecting arm 501 and a second connecting arm 502 rotatably connected to the outside of the connecting frame 102. A fourth stepper motor 503 is fixedly installed on the outside of the connecting frame 102. The output end of the fourth stepper motor 503 is fixedly connected to a fourth lead screw 504. A movable block 506 is threadedly connected to the outer wall of the fourth lead screw 504. The outer ends of the first connecting arm 501 and the second connecting arm 502 are rotatably connected to a scissor telescopic member 507. The scissor telescopic member 507 is rotatably connected to the movable block 506. A third connecting arm 508 and a fourth connecting arm 509 are also rotatably connected to the outside of the second sliding frame 104. The third connecting arm 508 and the fourth connecting arm 509 are respectively rotatably connected to the other two ends of the scissor telescopic member 507. A fourth guide rod 505 is also welded to the outside of the connecting frame 102. The movable block 506 is slidably connected to the fourth guide rod 505.

[0054] Those skilled in the art will understand that the output of the fourth stepper motor 503 drives the fourth lead screw 504 to rotate, causing the movable block 506 to reciprocate horizontally. When the movable block 506 moves to the left, the scissor telescopic member 507 is in an extended state, causing the first sliding frame 103 to extend out of the connecting frame 102, and also causing the second sliding frame 104 to extend out of the first sliding frame 103. When the movable block 506 moves to the right, it causes the first sliding frame 103 to extend into the connecting frame 102, and also causes the second sliding frame 104 to extend into the first sliding frame 103. In summary, this achieves the horizontal reciprocating motion of the drilling mechanism 7.

[0055] Example 6

[0056] Please refer to Figure 7 As shown, the clamping mechanism 6 includes a dual-axis electric actuator 601 and an electric actuator 602. The dual-axis electric actuator 601 is fixedly connected inside the two sets of connecting frames 102. The electric actuator 602 is provided with two sets, which are respectively fixedly installed on the outside of the two sets of second sliding frames 104. The two output ends of the dual-axis electric actuator 601 and the output ends of the two sets of electric actuators 602 are all fixedly connected to the mounting frame 603. The second threaded rod 604 is rotatably connected inside the mounting frame 603. The threads at both ends of the second threaded rod 604 have opposite directions of rotation, and the two ends of the outer wall of the second threaded rod 604 are threadedly connected to the clamping plate 607. The clamping plate 607 is slidably connected to the second fixed rod 605. The second fixed rod 605 is welded inside the mounting frame 603, and the outside of the mounting frame 603 is provided with a second servo motor 606 that drives the second threaded rod 604 to rotate.

[0057] Those skilled in the art will understand that by controlling the synchronous extension or retraction of the two output ends of the dual-axis electric actuator 601, the two sets of mounting frames 603 are moved away from or closer to each other, making it easier to locate the positions of the hydraulic supports installed on both sides of the mine roadway. Similarly, controlling the extension or retraction of the output end of the electric actuator 602 also makes it easier for the mounting frame 603 on the outer side of the second sliding frame 104 to locate the positions of the hydraulic supports installed on both sides of the mine roadway. By controlling the output end of the second servo motor 606 to rotate, the two sets of clamping plates 607 are moved closer to or further apart. When the two sets of clamping plates 607 are close to each other, the outer wall of the hydraulic support is fixed.

[0058] Example 7

[0059] Please refer to Figure 9 As shown, the drilling mechanism 7 includes a fixed plate 701, which is welded to the outer end of the second sliding frame 104. A second drive motor 702 is provided on the outer wall of the fixed plate 701. The output end of the second drive motor 702 passes through the outer wall of the fixed plate 701 and is fixedly connected to the mounting plate 703. A third drive motor 704 is fixedly connected to the bottom of the mounting plate 703. The output end of the third drive motor 704 is fixedly connected to the rotating frame 705. A multi-stage electric telescopic rod 706 is rotatably connected inside the rotating frame 705. A frame 707 is fixedly installed on the output end of the multi-stage electric telescopic rod 706. A fourth drive motor for driving the multi-stage electric telescopic rod 706 to rotate is provided on the outer side of the rotating frame 705.

[0060] Please refer to Figure 9 and Figure 10 As shown, a fifth stepper motor 708 is provided on the inner wall of the frame 707. A fifth lead screw 709 is fixedly installed at the output end of the fifth stepper motor 708. A mounting part 711 is threadedly connected to the outer wall of the fifth lead screw 709. The mounting part 711 is slidably connected to the fifth guide rod 710. The fifth guide rod 710 is welded inside the frame 707. A motor 712 is fixedly connected to the outer side of the mounting part 711. The output end of the motor 712 is fixedly connected to the dual-axis cylinder 713 through a connector. Clamping blocks 714 are fixedly installed at both output ends of the dual-axis cylinder 713. The two sets of clamping blocks 714 are used to fix the drill rod 715.

[0061] Those skilled in the art will understand that by controlling the output of the second drive motor 702 to rotate, the mounting plate 703 rotates, causing the multi-stage electric telescopic rod 706 to flip, allowing it to face either upwards or downwards; the output of the third drive motor 704 drives the rotating frame 705 to rotate, thus rotating the multi-stage electric telescopic rod 706 and changing the orientation of the borehole; furthermore, the output of the fourth drive motor rotates the multi-stage electric telescopic rod 706 to an inclined state, changing the angle of the borehole. In summary, through the combined action of the second drive motor 702, the third drive motor 704, and the fourth drive motor, the drill rod 715 can drill at any position within the roadway as needed.

[0062] It is worth noting here that the present invention provides two sets of drilling mechanisms 7. The present invention can place the connecting frame 102, the first sliding frame 103 and the second sliding frame 104 as a whole at the middle position of the internal height of the mine roadway, dividing the internal part of the mine roadway into two regions. The position above the connecting frame 102, the first sliding frame 103 and the second sliding frame 104 as a whole is the first region, and the position below the connecting frame 102, the first sliding frame 103 and the second sliding frame 104 as a whole is the second region. The two sets of drilling mechanisms 7 can be used to drill holes at any position in the first region and the second region as needed.

[0063] After the drill rod 715 finds the drilling point, the output end of the fifth stepper motor 708 drives the fifth lead screw 709 to rotate, causing the mounting part 711 to move closer to the drilling point. This drives the drill rod 715 to move closer to the drilling point. At the same time, the output end of the motor 712 is synchronously controlled to rotate, thus driving the drill rod 715 to rotate, thereby realizing drilling at the drilling point.

[0064] Example 8

[0065] Please refer to Figure 11As shown, both the drill rod 715 and the extension rod 411 are equipped with a connecting mechanism 8 at their tops. The connecting mechanism 8 includes a rotating gear ring 801. A set of rotating gear rings 801 and several sets of driven gears 802 are rotatably connected to the inner walls of the top ends of both the drill rod 715 and the extension rod 411. The driven gears 802 mesh with the rotating gear ring 801. A drive motor 803 is also fixedly installed on the inner walls of the top ends of both the drill rod 715 and the extension rod 411. The output end is fixedly connected to one of the driven gears 802. The drill rod 715 and the extension rod 411 are also fixedly installed with a slide rail 804. A clamping member 805 is slidably connected on the slide rail 804. Both ends of the clamping member 805 are sharp. Several sets of clamping members 805 are equipped with teeth that mesh with the driven gear 802. Several sets of slots 806 are also opened through the top outer wall of the drill rod 715 and the extension rod 411 for the clamping members 805 to pass through.

[0066] Those skilled in the art will understand that, after the drill rod 715 is drilled into the borehole in the mine roadway, if the drilling depth is insufficient, an extension rod 411 is needed to extend the drilling depth. To prevent the drill rod 715 from accidentally dislodging from the borehole due to vibration, the output end of the transmission motor 803 drives one set of driven gears 802 to rotate, causing the rotating gear ring 801 to rotate synchronously. Consequently, all driven gears 802 rotate synchronously, driving all clamping parts 805 to move synchronously towards the center position away from the rotating gear ring 801. All clamping parts 805 pass through the slot 806 synchronously, and their sharp ends abut against the inner wall of the drilled hole, thereby fixing the drill rod 715 to the inner wall of the hole and preventing it from accidentally dislodging from the borehole, thus meeting the needs of the workers.

[0067] After the extension rod 411 is installed, its bottom is inserted into the opening of the drill rod 715 exposed outside the drill hole. At this time, the drive motor 803 inside the drill rod 715 is driven in the reverse direction to rotate, so that all the clamping parts 805 move synchronously toward the center position close to the rotating gear ring 801, thereby fixing the extension rod 411 to the drill rod 715. Then the drilling steps can be repeated. If the drilling depth is still insufficient, the above steps are repeated. First, the drive motor 803 inside the extension rod 411 located on the outermost side of the drill hole is rotated, so that the clamping parts 805 abut against the inner wall of the hole. Similarly, it is to prevent them from falling off first. Then, the other extension rod 411 is fixedly installed. The steps are repeated until the required drilling depth is achieved.

[0068] The drilling rig in this invention can directly enter the mine roadway for drilling under normal use. If the mine roadway is too narrow, this invention adopts a split design, leaving the tracked vehicle 1 outside the mine roadway. The specific principle is as follows:

[0069] S1. Hydraulic supports are pre-installed on both sides of the mine roadway. Based on the internal height of the mine roadway, the output ends of two sets of first stepper motors 204 are synchronously driven to rotate, thereby changing the overall height of the machine body 101, connecting frame 102, first sliding frame 103 and second sliding frame 104. The connecting frame 102, first sliding frame 103 and second sliding frame 104 are placed at the middle position of the internal height of the mine roadway, dividing the interior of the mine roadway into two areas. The position higher than the connecting frame 102, first sliding frame 103 and second sliding frame 104 is the first area, and the position lower than the connecting frame 102, first sliding frame 103 and second sliding frame 104 is the second area.

[0070] S2. The output end of the fourth stepper motor 503 drives the fourth lead screw 504 to rotate, causing the movable block 506 to move to the left. The scissor telescopic component 507 is in the extended state, which drives the first sliding frame 103 to extend out of the connecting frame 102, and also drives the second sliding frame 104 to extend out of the first sliding frame 103, causing the second sliding frame 104 to enter the mine roadway. According to the drilling requirements, the two sets of drilling mechanisms 7 are controlled to drill at any position in the first area and the second area respectively.

[0071] S3. If the tunnel is too long, that is, if the second sliding frame 104 and the first sliding frame 103 are both extended, and there are still areas in the tunnel where drilling is not possible, then the telescopic mechanism 5 is controlled so that the second sliding frame 104 is located where the hydraulic support exists. The extension of the output end of the electric push rod 602 is controlled so that the mounting frame 603 is close to the side hydraulic support. The output end of the second servo motor 606 is controlled to rotate, which drives the two sets of clamping plates 607 to move closer to each other, thereby fixing the outer wall of the hydraulic support, that is, fixing the second sliding frame 104 to the hydraulic support.

[0072] S4. The output end of the first servo motor 304 drives the first threaded rod 302 to rotate, causing the two sets of clamping parts 305 to move away from each other, releasing the fixation on the machine body 101. Through the action of the telescopic mechanism 5, since the second sliding frame 104 is fixed on the hydraulic support, it can retract, and the connecting frame 102 is also located at the position where the hydraulic support exists. Similarly, the synchronous extension of the two output ends of the dual-axis electric actuator 601 is controlled, so that the two sets of mounting frames 603 are also moved closer to the positions of the hydraulic supports on both sides, and also through... The hydraulic support is fixed by two sets of clamping plates 607, and the connecting frame 102 is also fixed to the hydraulic support in the same way. In summary, in this way, the connecting frame 102 is fixed to the hydraulic support while the second sliding frame 104 is not fixed, and the second sliding frame 104 is fixed to the hydraulic support while the connecting frame 102 is not fixed. With the cooperation of the telescopic mechanism 5, the machine body 101 can move horizontally in the mine roadway. Therefore, it is possible to drill holes at any position in the roadway as needed, which improves the practicality of the device.

[0073] S5. During drilling, the second drive motor 702, the third drive motor 704 and the fourth drive motor work together to help the drill rod 715 find the drilling point. Then, the output of the fifth stepper motor 708 drives the fifth lead screw 709 to rotate, causing the mounting part 711 to move closer to the drilling point, thus moving the drill rod 715 closer to the drilling point. At the same time, the output of the synchronous control motor 712 rotates, thus driving the drill rod 715 to rotate, thereby realizing drilling at the drilling point.

[0074] S6. If the drilling depth is insufficient, an extension rod 411 is needed to extend the drilling depth. To prevent the drill rod 715 from accidentally dislodging from the drilling point due to vibration, the output end of the transmission motor 803 drives one set of driven gears 802 to rotate, causing the rotating gear ring 801 to rotate synchronously. Consequently, all driven gears 802 rotate synchronously, driving all clamping parts 805 to move synchronously away from the center of the rotating gear ring 801. All clamping parts 805 pass through the slot 806 synchronously, and their sharp ends abut against the inner wall of the drilled hole, thereby fixing the drill rod 715 to the inner wall of the hole and preventing it from accidentally dislodging from the drilling point, thus meeting the needs of the workers. Afterward, the two output ends of the two sets of dual-axis cylinders 713 drive the two sets of clamping blocks 714 to release the fixation of the drill rod 715.

[0075] S7. Through the combined action of the second drive motor 702, the third drive motor 704, and the fourth drive motor, the frame 707 is brought into a horizontal position and faces the storage mechanism 4. The output end of the third stepper motor 409 drives the third lead screw 407 to rotate, causing the push plate 410 to move towards the frame 707, pushing the extension rod 411 out of the through hole on the left side of the storage frame 406. The two output ends of the two sets of dual-axis cylinders 713 drive the two sets of clamping blocks 714 to fix the outer end of the extended rod 411. Then, the extension rod 411 reaches the position of the drill rod 715 stored in the drill hole, and the bottom of the extension rod 411 extends into the drill hole. Inside the opening of the external drill rod 715, the drive motor 803 inside the drill rod 715 is rotated in the reverse direction, causing all the clamping parts 805 to move synchronously toward the center position near the rotating gear ring 801, thereby fixing the extension rod 411 onto the drill rod 715. Then the drilling steps can be repeated. If the drilling depth is still insufficient, the above steps are repeated. First, the drive motor 803 inside the extension rod 411 located on the outermost side of the hole is rotated, causing the clamping parts 805 to abut against the inner wall of the hole. Similarly, it is to prevent them from detaching first. Then, the other extension rod 411 is fixedly installed. The steps are repeated until the required drilling depth is achieved, which is convenient and quick.
