Description

Technical Field

[0001] This utility model belongs to the field of coal mine tunnel construction and relates to a drill rod sorting and feeding device for coal mine tunnel drilling rigs. Background Technology

[0002] With economic development, energy remains the foundation of national economic development, with coal, oil, and natural gas being the three major energy resources. Although coal mine safety has improved significantly and mass casualty accidents have decreased, accidents still occur, especially minor injuries. Therefore, underground mining in my country mainly relies on drainage, which is divided into local and cross-layer drainage. The drainage process includes drilling, sealing, and connection of the drainage holes. During the drilling process, drill rods need to be transported within the coal mine tunnels.

[0003] Existing drill pipes are transported via conveyor belts, but conveyor belts only improve the horizontal movement efficiency. The unloading of drill pipes still requires manual movement by personnel. Using robotic arms for unloading is more costly and has limited unloading distance. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a drill rod sorting and feeding device for coal mine tunnel drilling rigs. This device solves the problems of existing drill rod transportation via conveyor belts, which only improves horizontal movement, while manual unloading of drill rods is still required. Using robotic arms for unloading is costly and has limited unloading distance.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A drill rod sorting and feeding device for a coal mine tunnel drilling rig includes a conveyor belt mechanism, a feeding device, and a drill rod storage box;

[0007] The conveyor belt mechanism includes two fixed plates, a rotating shaft, a conveyor belt, and a first motor; the two fixed plates are parallel and opposite to each other, and multiple rotating shafts are rotatably arranged between the two fixed plates. The conveyor belt is rotatably arranged outside the multiple rotating shafts, and one end of one of the rotating shafts extends out of the fixed plate and is connected to the first motor.

[0008] The feeding device is mounted on a conveyor belt and includes a feeding tray and a feeding tray movable seat below it; the base of the feeding tray movable seat is fixed to the conveyor belt; the top surface of the feeding tray has multiple rod grooves, one end of which is a first arc-shaped opening, and the other end is fixed with an electromagnet; the side of the feeding tray near the first arc-shaped opening is hinged to the feeding tray movable seat, and the side of the feeding tray near the electromagnet is connected to the feeding tray movable seat through a vertically telescopic hydraulic cylinder.

[0009] The drill rod storage box is located on one side of the conveyor belt mechanism. Inside the drill rod storage box, there are multiple vertical partitions to divide its interior into multiple equally spaced storage spaces. Each storage space contains multiple drill rods arranged vertically. At the bottom of the storage space, there is a vertical electric push rod to push the drill rods vertically out. Each storage space has a second arc-shaped opening on one side of its top, which is aligned with the first arc-shaped opening and matches the drill rods. A sliding push plate is vertically installed on the top of the partition. The sliding push plate can push the drill rods from the drill rod storage box into the feeding tray under the action of a second motor and a threaded rod.

[0010] This utility model also includes the following technical features:

[0011] Specifically, a storage battery is provided at the top center of the feed tray moving seat, and the storage battery is electrically connected to the electromagnet; an electric turntable is provided on the base at the bottom of the feed tray moving seat, and the bottom end of the feed tray moving seat is fixed on the electric turntable.

[0012] Specifically, the feeding tray is equipped with an identifier, which includes a size measuring instrument and a hole position measuring instrument; a display (27) is provided on one side edge of the top of the feeding tray (12).

[0013] Specifically, the feeding tray (12) includes multiple rectangular support blocks arranged in parallel, each rectangular support block is provided with a rod groove (13), and multiple hydraulic cylinders (17) correspond one-to-one with multiple rectangular support blocks.

[0014] Specifically, the top of the partition is provided with a sliding groove, and the bottom of the sliding push plate is provided with multiple sliders, which can be installed in conjunction with the sliding groove and slide along the sliding groove.

[0015] Specifically, one end of the sliding push plate extends out of the drill rod storage box, and a threaded rod is threaded onto the extended end. One end of the threaded rod extends out of the sliding push plate and is connected to a second motor, which is fixed to the drill rod storage box. The other end of the threaded rod is rotatably disposed inside a shaft retainer, which is fixed to the outer wall of the drill rod storage box. The threaded rod is perpendicular to the sliding push plate.

[0016] Specifically, the drill rod storage box is equipped with a position sensor on the side near the conveyor belt for detecting the position of the loading tray.

[0017] Specifically, there are multiple feeding devices, including a first feeding device and a second feeding device.

[0018] Specifically, the end of the electric push rod is provided with a rectangular push plate for pushing out the drill rod.

[0019] Specifically, the bottom of the fixing plate is provided with multiple support frames.

[0020] Compared with the prior art, this utility model has the following technical effects:

[0021] In this invention, when the hydraulic cylinder pushes the feeding disc to rotate, the electromagnet is turned off. After the drill rod loses the attraction of the electromagnet, it slides along the first arc-shaped opening of the rod groove into the drill hole, reducing manual handling and moving work, saving time and effort.

[0022] This invention uses an electromagnet to attract and fix the end of the drill rod when energized, preventing the drill rod from sliding or falling during movement. Furthermore, the electromagnet inside each rod groove can be individually controlled to attract the drill rod.

[0023] When the electric turntable controls the moving seat of the feeding plate, the feeding plate can rotate simultaneously, thereby controlling the orientation of the first arc-shaped opening on the feeding plate, so that the drill rod can be conveyed and inserted into the drill holes in different positions of the inner wall of the coal mine tunnel, which is highly practical.

[0024] This utility model's identifier can be used to read and identify drill rod information, thereby delivering the corresponding drill rod to the designated borehole location, making it highly targeted.

[0025] When the position sensor of this utility model detects that the feeding tray has moved to the corresponding drill rod storage box position, it activates the electric push rod and the second motor. The electric push rod pushes the rectangular push plate upward so that the end of the drill rod corresponds to the second arc-shaped opening. When the second motor starts, it drives the threaded rod to rotate. When the threaded rod rotates, it causes the sliding push plate to move along the slide groove and push the drill rod into the rod groove on the upper surface of the feeding tray to complete the discharge. When the drill rod moves to the corresponding drilling position, the electromagnet is turned off. At this time, the drill rod loses the attraction of the electromagnet, and the hydraulic cylinder is activated. The hydraulic cylinder lifts the feeding tray, causing the feeding tray to tilt. When the feeding tray tilts, the drill rod slides along the first arc-shaped opening of the rod groove into the drilling hole.

[0026] In this invention, the structure of the feeding tray is improved. When the corresponding drill rod needs to be inserted into the drill hole, the corresponding hydraulic cylinder is activated. The hydraulic cylinder will lift and tilt the corresponding drill rod, so that the drill rod slides into the corresponding drill hole. Since only one rectangular support block needs to be tilted, the electromagnet does not need to be activated when conditions permit. It can be used according to actual needs, and the energy consumption is small.

[0027] In this invention, the drill rod length, diameter, and hole position can be obtained through the setting of the identifier, and the drill rod can be rotated by the third motor until the hole position on the drill rod is correct. This makes it convenient to control the drill rod to be inserted into the borehole at the appropriate hole position, so that when the drill rod is grouted, the root system of the grout can be anchored in the appropriate position.

[0039] The following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments. All equivalent modifications made based on the technical solutions of this application fall within the protection scope of the present invention.

[0040] Example:

[0041] like Figures 1 to 6 As shown in the figure, this embodiment provides a drill rod sorting and feeding device for coal mine tunnel drilling rigs, characterized in that it includes a conveyor belt mechanism, a feeding device, and a drill rod storage box 4.

[0042] The conveyor belt mechanism includes two fixed plates 25, a rotating shaft, a conveyor belt 1, and a first motor 2. The two fixed plates 25 are parallel and opposite to each other, and multiple rotating shafts are rotatably arranged between the two fixed plates 25. The conveyor belt 1 is arranged outside the multiple rotating shafts, and one end of one of the rotating shafts extends out of the fixed plate 25 and is connected to the first motor 2.

[0043] The unloading device is mounted on the conveyor belt 1 and includes a loading tray 12 and a loading tray moving seat 15 below it. The base 20 at the bottom of the loading tray moving seat 15 is fixed to the conveyor belt 1. The top surface of the loading tray 12 is provided with multiple rod grooves 13. One end of the rod groove 13 is a first arc-shaped opening 19, and the other end is fixed with an electromagnet 14. The side of the loading tray 12 near the first arc-shaped opening 19 is hinged to the loading tray moving seat 15. The side of the loading tray 12 near the electromagnet 14 is connected to the loading tray moving seat 15 through a vertical telescopic hydraulic cylinder 17.

[0044] The drill rod storage box 4 is located on one side of the conveyor belt mechanism. Inside the drill rod storage box 4, there are multiple vertical partitions 5 to divide its interior into multiple equally spaced storage spaces. Each storage space contains multiple drill rods 23 arranged vertically. At the bottom of the storage space, there is a vertical electric push rod 22 to push the drill rod 23 vertically. Each storage space has a second arc-shaped opening 24 on one side of its top. The second arc-shaped opening 24 is aligned with the first arc-shaped opening 19 and is matched with the drill rod 23. A sliding push plate 6 is vertically provided on the top of the partition 5. The sliding push plate 6 can push the drill rod 23 from the drill rod storage box 4 into the feeding tray 12 by the action of the second motor 7 and the threaded rod 8.

[0045] The overall device of this utility model is installed inside the coal mine tunnel. At this time, the first motor 2 is started, driving the rotating shaft and the conveyor belt 1 to rotate. Multiple support frames 3 are provided at the bottom of the two fixed plates 25. The support frames 3 can support the two fixed plates 25 and keep the conveyor belt 1 away from the ground to prevent the conveyor belt 1 from colliding with the ground.

[0046] A battery is provided at the top center of the feeding tray moving seat 15, which is electrically connected to the electromagnet 14. An electric turntable 21 is provided on the base 20 at the bottom of the feeding tray moving seat 15. The bottom end of the feeding tray moving seat 15 is fixed on the electric turntable 21. When the electric turntable 21 controls the feeding tray moving seat 15, the feeding tray 12 can rotate simultaneously, thereby controlling the orientation of the first arc-shaped opening 19 on the feeding tray 12, so that the drill rod 23 can be conveyed and inserted into the drill hole in the inner wall of different positions in the coal mine tunnel, which is highly practical.

[0047] The feeding tray 12 is equipped with an identifier 29, which is used to identify the information of the drill rod 23, thereby conveying the corresponding drill rod 23 to the designated drilling position, making it highly targeted. The identifier 29 includes a dimension measuring instrument and a hole position measuring instrument. The dimension measuring instrument is used to measure the length and diameter of the drill rod 23, and the hole position measuring instrument is used to measure the hole position on the drill rod 23. If the hole position deviates from the set threshold, the third motor 30 connected to the electromagnet 14 is activated. The third motor 30 drives the electromagnet 14 to rotate through the rotating shaft. During the rotation of the electromagnet 14, the drill rod 23 is rotated to correct the hole position.

[0048] A display 27 is provided on one side edge of the top of the feeding tray 12.

[0049] A hinge seat 18 is provided on one side of the top of the feeding tray moving seat 15 to prevent it from tipping over during movement. One side of the bottom of the feeding tray 12 is rotatably disposed inside the hinge seat 18.

[0050] A groove 16 is provided on the other side of the top of the feeding tray moving seat 15. Multiple hydraulic cylinders 17 are installed inside the groove 16. The top of the hydraulic cylinder 17 is provided with a telescopic end. The top of the telescopic end is connected to the bottom of the feeding tray 12. When the hydraulic cylinder 17 pushes the feeding tray 12 to rotate, the electromagnet 14 is turned off. After the drill rod 23 loses the attraction of the electromagnet 14, it slides along the first arc-shaped opening 19 of the rod groove 13 into the drill hole, reducing manual handling and moving work, saving time and effort.

[0051] The top of the partition 5 is provided with a sliding groove 26, and the bottom of the sliding push plate 6 is provided with multiple sliders. The sliders can be installed in conjunction with the sliding groove 26 and slide along the sliding groove 26.

[0052] One end of the sliding push plate 6 extends out of the drill rod storage box 4. A threaded rod 8 is threaded onto the extended end. One end of the threaded rod 8 extends out of the sliding push plate 6 and is connected to the second motor 7. The second motor 7 is fixed on the drill rod storage box 4. The other end of the threaded rod 8 is rotatably set inside the shaft retainer 9. The shaft retainer 9 is fixed to the outer wall of the drill rod storage box 4. The threaded rod 8 is perpendicular to the sliding push plate 6.

[0053] A position sensor 28 for detecting the position of the feed tray 12 is provided on the side of the drill pipe storage box 4 near the conveyor belt 1.

[0054] There are multiple feeding devices, including a first feeding device 10 and a second feeding device 11.

[0055] The electric push rod 22 has a rectangular push plate at its end for pushing out the drill rod 23.

[0056] The drill pipe storage box 4 has multiple second arc-shaped openings 24 at its top end near the conveyor belt 1. Each of the multiple second arc-shaped openings 24 corresponds to a position in the storage space. The second arc-shaped openings 24 match the drill pipe 23. The positions of the second arc-shaped openings 24 and the first arc-shaped openings 19 are also corresponding.

[0057] In actual operation, the multiple drill rods 23 that need to be transported are placed in the storage space divided by the partition 5. When the drill rods 23 need to be transported, the electric push rod 22 can be activated to push the electric push rod 22 upward. At this time, the drill rods 23 will be pushed out of the storage space and correspond to the position of the second arc-shaped opening 24 on one side of the drill rod storage box 4. It should be noted that the pointed end of the drill rod 23 is facing away from the first feeding device 10. Multiple drill rods 23 can be raised at one time to improve the transportation efficiency. Moreover, due to the obstruction of the partition 5, the drill rods 23 in each storage space will not collide or roll.

[0058] Once the heights of the multiple drill rods 23 are aligned with the second arc-shaped opening 24, the second motor 7 is started. The rotation of the second motor 7 causes the threaded rod 8 to rotate, which in turn drives the sliding push plate 6 to move toward the first feeding device 10, pushing the multiple drill rods 23 onto the first feeding device 10. It should be noted that the positions of the first feeding device 10 and the second arc-shaped opening 24 correspond to each other. The top of the feeding tray 12 has multiple rod grooves 13, one end of which is provided with a first arc-shaped opening 19, and the other end of which is fixedly provided with an electromagnet 14. A battery is provided in the middle of the top of the feeding tray moving seat 15, and the electromagnet 14 is electrically connected to the battery. A display 27 is provided on one side of the top of the feeding tray 12. The end of the drill rod 23 away from the pointed end is made of iron, or the entire drill rod 23 is made of iron. The entire drill rod 23 is usually made of stainless steel.

[0059] When the conveyor belt 1 transports the first feeding device 10 to one side of the drill rod storage box 4, the positions of the second arc-shaped opening 24 and the first arc-shaped opening 19 correspond. The sliding push plate 6 pushes multiple drill rods 23 into the corresponding rod slots 13. At this time, one end of the drill rod 23 will correspond to the electromagnet 14 inside the rod slot 13. The electromagnet 14 is energized and attracts the end of the drill rod 23 to form a fixed position, preventing the drill rod 23 from sliding or falling during movement. Moreover, the electromagnet 14 inside each rod slot 13 can be individually controlled to attract the drill rod.

[0060] This utility model relates to a drilling rod sorting and feeding device for coal mine tunnel drilling rigs, and its sorting and feeding method includes the following steps:

[0061] S1: Material is discharged twice. When the position sensor 28 senses that the feeding tray 12 has moved to the corresponding drill rod storage box 4, the electric push rod 22 and the second motor 7 are started. The electric push rod 22 pushes the rectangular push plate up so that the end of the drill rod 23 corresponds to the second arc-shaped opening 24. When the second motor 7 is started, it drives the threaded rod 8 to rotate. When the threaded rod 8 rotates, the sliding push plate 6 moves along the slide groove and pushes the drill rod 23 into the rod groove 13 on the upper surface of the feeding tray 12 to complete the discharge.

[0062] S2: Information recognition. The information of the drill rod 23 is read and recognized by the identifier 29 on the drill rod storage box 4. When the first motor 2 starts, it drives the conveyor belt 1 to convey the material. After the conveyor belt 1 moves the feeding plate 12 to the designated position in the coal mine tunnel, the corresponding drill rod 23 is inserted into the borehole in the coal mine tunnel.

[0063] S3: Insert drill rod 23. After drill rod 23 moves to the corresponding drilling position, turn off electromagnet 14. At this time, drill rod 23 loses the attraction of electromagnet 14 and starts hydraulic cylinder 17. Hydraulic cylinder 17 lifts the feeding plate 12, causing the feeding plate 12 to tilt. When the feeding plate 12 tilts, the drill rod 23 slides along the first arc-shaped opening 19 of the rod groove 13 into the drilling hole.

[0064] In other embodiments, the feeding tray 12 includes multiple rectangular support blocks arranged in parallel, each rectangular support block is provided with a rod groove 13, and multiple hydraulic cylinders 17 correspond one-to-one with multiple rectangular support blocks. Since there are multiple drill rods 23 stored on the feeding tray 12, if the entire feeding tray 12 is supported every time a drill rod is installed, the energy consumption will be large, and multiple electromagnets 14 need to be activated in real time to attract and fix other drill rods 23.

[0065] Therefore, by improving the structure of the feeding tray 12, when the corresponding drill rod 23 needs to be inserted into the drill hole, the corresponding hydraulic cylinder 17 is activated. The hydraulic cylinder 17 will lift and tilt the corresponding drill rod 23, so that the drill rod 23 slides into the corresponding drill hole. Since only one rectangular support block needs to be tilted, the electromagnet 14 does not need to be activated when conditions permit. It can be used according to actual needs, and the energy consumption is small.

[0066] It should be noted that, as Figures 7 to 8As shown, firstly, the position sensor 28 detects the position of the feeding tray 12. If the feeding tray 12 moves to the side of the drill rod storage box 4, the electric push rod 22 and the second motor 7 are activated. The electric push rod 22 pushes the drill rods 23 in the storage chamber upward through the rectangular push plate, so that the upper drill rod 23 corresponds to the position of the second arc-shaped opening 24. Then, when the second motor 7 is activated, the threaded rod 8 rotates. When the threaded rod 8 rotates, the sliding push plate 6 moves along the slide groove and pushes the drill rod 23 into the rod groove 13 on the upper surface of the feeding tray 12, completing the discharge. When the drill rod 23 is in use, the threaded rod 8 rotates. When the threaded rod 8 rotates, the sliding push plate 6 moves along the slide groove and pushes the drill rod 23 into the rod groove 13 on the upper surface of the feeding tray 12, completing the discharge. When rod 23 is on the feeding tray 12, the identifier 29 is used to read and identify the information of the drill rod 23 to determine whether the drilling position is close to the position of the first arc-shaped opening 19. If the position of the first arc-shaped opening 19 and the drilling position correspond, the drill rod 23 is inserted into the drilling hole by the corresponding hydraulic cylinder 17 and electromagnet 14. If the drilling position does not correspond to the position of the first arc-shaped opening 19, the electric turntable 21 is started. The electric turntable 21 drives the feeding tray 12 to rotate 180 degrees and then determines again whether the drilling position is close to the position of the first arc-shaped opening 19.

[0067] The display 27 can be used to display relevant control programs for easy operation.

[0068] The identifier 29 includes a size measuring instrument and a hole position measuring instrument. The identifier 29 is used in conjunction with a rotating assembly, which includes a third motor 30, such as... Figure 6 The third motor 30 is fixed at one end of the feeding tray 12, and the electromagnet 14 is rotatably connected to the end face of the rod groove 13. The rotating shaft of the third motor 30 moves through the feeding tray 12 and is fixedly connected to the middle of the electromagnet 14. Figure 9 The information identification in S2 also includes the following steps:

[0069] Step 1: Use a hole position measuring instrument to measure the hole position on drill rod 23. If the hole position deviates from the set threshold, start the third motor 30. The third motor 30 drives the electromagnet 14 to rotate through the rotating shaft. During the rotation of the electromagnet 14, the drill rod 23 is rotated. Then use the hole position measuring instrument to measure the hole position on drill rod 23 again. When the hole position is correct, proceed to the next step of measurement.

[0070] In practical use, the rotation angle of the third motor 30 after each start can be set, such as 30 degrees or 15 degrees each time, until the hole position is correct before proceeding to the next measurement. In this utility model, the length, diameter and hole position of the drill rod 23 can be obtained through the setting of the identifier 29, and the third motor can make the drill rod 23 rotate until the hole position on the drill rod 23 is correct and then stop, which makes it convenient to control the drill rod 23 to be inserted into the borehole in a suitable hole position, so that when the drill rod is grouted, the root system of the grout can be anchored in a suitable position.

[0071] Step 2: Use a dimensional measuring instrument to measure the length and diameter of the drill rod 23, and then transport the drill rod 23 to a suitable drilling location for installation.

[0072] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0073] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0074] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
