Description

Technical Field

[0001] The utility model relates to the field of coal mine drilling, in particular to a coal mine roadway drilling device. Background Art

[0002] Coal mine roadway drilling equipment is a professional equipment used for drilling operations in coal mines. Its main functions and roles include geological exploration and coal seam analysis, as well as gas drainage and coal seam water injection. Generally speaking, coal mine roadway drilling equipment plays an important role in coal production and is one of the key tools to improve coal production efficiency and safety.

[0003] There are still certain deficiencies in the use of traditional coal mine roadway drilling devices: during the use of traditional coal mine roadway drilling rigs, the water inside the drill holes directly flows onto the ground of the roadway, forming puddles or flowing everywhere, which brings certain troubles to the surrounding operating machines and the staff placing drill pipes, and this part of the water cannot be effectively utilized, resulting in waste. Secondly, when retrieving the drill pipe after drilling, when the surface of the drill pipe contacts the coal seam or rock formation, more impurities are easily attached to its surface, and the current equipment is not convenient for quickly cleaning the surface when the workers put it back on the storage rack.

[0004] Therefore, it is necessary to provide a new coal mine roadway drilling device to solve the above technical problems. Summary of the Utility Model

[0005] The technical problem solved by the utility model is to provide a coal mine roadway drilling device which is convenient for quickly cleaning the surface of the retrieved drill pipe, and at the same time can effectively recover and utilize the sewage flowing out of the drill hole.

[0006] To solve the above technical problems, a coal mine roadway drilling device provided by the utility model includes: a base, a storage component and a recovery component. The storage component includes a storage box, the storage box is arranged on one side of the base, a plurality of longitudinally distributed placement racks are arranged at equal intervals inside the storage box, and a plurality of the placement racks are fixedly connected by connecting pieces. A shell is fixedly connected to the surface of one side wall of the storage box. A plurality of equally spaced insertion holes are opened on the surfaces of the left and right side walls of the shell. A bracket is fixedly connected to the surface of the side wall of the shell opposite to the storage box. Cleaning pads are bonded to the inner walls of a plurality of insertion holes on the side of the shell opposite to the bracket. Branch pipes are fixedly connected to the inner parts of the shell above and below the insertion holes. A plurality of spray heads are installed on the surfaces of the side walls of the two branch pipes close to each other.

[0007] The recycling component includes a cover body and a water tank. Ear plates are fixedly connected to the front and rear side walls of the cover body. A pin rod is inserted into the ear plates. A drain pipe is connected to the bottom of the cover body. The water tank is arranged on one side of the base. The bottom of the drain pipe is located above the water tank. A filter element is fixedly connected inside the water tank. A first rotating door and a second rotating door are hinged to the surface of one side wall of the water tank. The first rotating door and the second rotating door are respectively located above and below the filter element.

[0008] As a further solution of the present utility model, push plates are arranged on the upper side of the inner wall of the bottom of the water tank and above the filter element. A connecting rod is fixedly connected between the two push plates. The connecting rod is slidably connected to the side wall of the water tank.

[0009] Through the above technical solution, during the use of a traditional coal mine roadway drilling rig, the water inside the drill hole directly flows onto the ground of the roadway, forming water puddles or flowing everywhere, which brings certain troubles to the surrounding operating machines and the staff placing drill pipes, and this part of the water cannot be effectively utilized, resulting in waste. In this device, the user can set a cover body outside the drill hole and fix it with a pin rod. Then, the water flowing out of the drill hole will flow into the water tank along the drain pipe instead of being directly discharged onto the ground of the roadway, avoiding trouble for the workers during work. Then, the filter element will filter the sewage, facilitating the reuse of the filtered water later. After the water tank is used for a period of time, more sediment, coal blocks, etc. will accumulate on the filter element, and some impurities will also accumulate at the bottom of the water tank due to the precipitation of water. At this time, the user can open the first rotating door and the second rotating door and push the connecting rod, so that the two push plates will push away the impurities on them. This structural design makes the cleaning of the water tank more convenient and conducive to use. In addition, the large-particle impurities are filtered out by the filter element in the structure, effectively purifying the water entering the lower part. Since the nozzle is used to wash the drill pipe, the aperture is relatively large, and the nozzle extracts the upper layer of water after precipitation, so the situation of nozzle blockage will not occur.

[0010] As a further solution of the present utility model, a water outlet pipe is connected to the side wall of the water tank below the filter element. A hose is installed at the end of the water outlet pipe. One ends of the two branch pipes penetrate through the housing and are connected to a communicating vessel. The end of the hose is connected to the communicating vessel.

[0011] Through the above technical solution, after the drilling is completed and the drill pipe is retrieved, when the surface of the drill pipe contacts the coal seam or rock stratum, more impurities are likely to adhere to its surface. Currently, the equipment is not convenient for quickly cleaning the surface when the worker puts it back on the storage rack. In this device, the user can start the driving motor to drive the threaded rod to rotate, and then let the movable part drive a certain layer of the storage rack on one side to reach the height of the bracket. Then the worker can push the disassembled drill pipe along the bracket into the shell. At this time, the pump body is turned on to pump the water in the water tank into the branch pipe to supply water to the nozzle. The nozzle will clean the impurities such as sediment on the surface of the drill pipe. After that, the water on the drill pipe will enter the storage rack after being wiped off by the cleaning pad. This structural design enables the worker to quickly clean the surface of the drill pipe when putting it back, preventing the storage box, storage rack, and the surface of the drill pipe from being severely soiled.

[0012] As a further solution of the present utility model, threaded rods are rotatably connected to the front and rear side walls of the storage box. A movable part is threadedly connected to the surface of the threaded rod. The movable part is fixedly connected to the adjacent connecting part. The connecting part is slidably connected to the storage box. A driving motor is fixedly connected to the side wall of the storage box through a support plate. The output end of the driving motor is fixedly connected to the top of the threaded rod.

[0013] Through the above technical solution, the driving motor can drive the threaded rod to rotate, and then let the movable part drive the storage rack to move up and down, thus facilitating the worker to store or retrieve the drill pipe.

[0014] As a further solution of the present utility model, bottom hydraulic rods are fixedly connected to the four corner positions of the base. Top hydraulic rods are fixedly connected to the front and rear side edge positions of the top of the base. Pressing plates are fixedly connected to the top of the top hydraulic rods and the bottom of the bottom hydraulic rods.

[0015] Through the above technical solution, before the drill rig works, the bottom hydraulic rods and the top hydraulic rods can be started, and the pressing plates at their ends respectively support on the surfaces of the bottom and top of the roadway, thereby preventing the drill rig from moving during the drilling process.

[0016] As a further solution of the present utility model, an installation part is arranged on the upper side of the base. Angle adjustment cylinders are hinged between the four corners of the installation part and the top of the base. A sliding seat is slidably connected to the top of the installation part. A power head is fixedly connected to the top of the sliding seat. Clamps are fixedly connected to the left and right side walls of the installation part through fixing plates. A control motor is fixedly connected to the side wall of the installation part. A lead screw is fixedly connected to the output end of the control motor. The end of the lead screw is rotatably connected to the installation part. The lead screw is threadedly connected to the sliding seat.

[0017] Through the above technical solution, since the top of the angle-adjusting oil cylinder is hinged to the mounting member and its bottom is hinged to the base, the angle-adjusting oil cylinders at the four corners of the mounting member can be controlled to lift the mounting member or change the pitch angle. When it is necessary to adjust the front end of the mounting member to tilt up, the two angle-adjusting oil cylinders at the front end can be started to extend until the drill bit can be aligned with the designated position to be drilled. When the overall horizontal lifting of the mounting member is required, controlling the four angle-adjusting oil cylinders to start simultaneously can complete it. The gripper and the power head in the structure are both main equipment on the coal mine drill. The gripper is a structure for fixing and clamping the drill pipe when necessary. The gripper in this structure is a common gripper for coal mine machinery on the market, that is, one side is a fixed end and the other side is a movable end driven by an oil cylinder. When fixing the drill pipe, the movable end is pushed by the oil cylinder to clamp the surface of the drill pipe on the fixed end. The power head will provide power for the drill pipe to rotate the drill bit.

[0018] As a further solution of the present invention, the power head is fixedly connected with a drill pipe. A plurality of drill pipes are provided and fixedly connected between adjacent two. Through holes are formed on the surface of the cover body, and one end of the drill pipe extends into the through holes.

[0019] Through the above technical solution, a suitable drill bit can be installed at the end of the drill pipe. By fixing the cover body on the drilling surface outside the drill pipe, the sewage flowing out of the drill hole can be intercepted to a certain extent, thus avoiding serious water accumulation on the ground of the coal mine roadway.

[0020] Compared with the related technology, a coal mine roadway drilling device provided by the present invention has the following beneficial effects:

[0021] 1. In the present utility model, during the use of traditional coal mine roadway drilling rigs, the water inside the drill hole directly flows onto the ground of the roadway, forming puddles or flowing everywhere, which brings certain troubles to the surrounding operating machines and the workers placing drill pipes. Moreover, this part of the water cannot be effectively utilized, resulting in waste. In this device, the user can set a cover outside the drill hole and fix it with a pin rod. Then, the water flowing out of the drill hole will flow along the drain pipe into the water tank instead of being directly discharged onto the ground of the roadway, avoiding troubles for the workers during work. After that, the filter element will filter the sewage, facilitating the subsequent reuse of the filtered water. After the water tank has been used for a period of time, more sediment, coal blocks, etc. will accumulate on the filter element, and some impurities will also accumulate at the bottom of the water tank due to the precipitation of water. At this time, the user can open the first rotating door and the second rotating door and push the connecting rod, so that the two push plates will push the impurities on them away. This structural design makes the cleaning of the water tank more convenient and conducive to use. In addition, in the structure, the filter element filters out large-particle impurities, effectively purifying the water entering the lower part. Since the nozzle is used to wash the drill pipe, its aperture is relatively large, and since the nozzle extracts the upper-layer water after precipitation, the situation of nozzle blockage will not occur;

[0022] 2. In the present utility model, after the drilling is completed and the drill pipe is retracted, when the surface of the drill pipe comes into contact with the coal seam or rock stratum, more impurities are likely to adhere to its surface. Currently, the equipment is not convenient for quickly cleaning the surface when the workers put it back on the storage rack. In this device, the user can start the driving motor to drive the threaded rod to rotate, and then let the moving part drive a certain layer of storage rack on one side to reach the height of the bracket. Then, the worker can push the disassembled drill pipe along the bracket into the shell. At this time, turn on the pump body to pump the water in the water tank into the branch pipe to supply water to the nozzle. The nozzle will wash the sediment and other impurities on the surface of the drill pipe. After that, the water on the drill pipe will be wiped off by the cleaning pad and then enter the storage rack. This structural design enables the workers to quickly clean the surface of the drill pipe when putting it back again, preventing the storage box, storage rack, and the surface of the drill pipe from being seriously soiled.

[0030] Please refer to Figures 1 to 4 , wherein, Figure 1 is the overall structural schematic diagram of a coal mine roadway drilling device in the present utility model; Figure 2 is the partial structural schematic diagram of a coal mine roadway drilling device in the present utility model;

[0031] Figure 3 Partial structural section of a coal mine roadway drilling device in the present utility model Figure 1 ; Figure 4 Partial structural section of a coal mine roadway drilling device in the present utility model Figure 2

[0032] A coal mine roadway drilling device includes: a base 1, a storage assembly 10 and a recycling assembly 11. The storage assembly 10 includes a storage box 14. The storage box 14 is arranged at one side of the base 1. A plurality of longitudinally distributed placing racks 17 are arranged at equal intervals inside the storage box 14. The plurality of placing racks 17 are fixedly connected through connecting members. A housing 18 is fixedly connected to the surface of one side wall of the storage box 14. A plurality of equally spaced jacks are provided on the surfaces of the left and right side walls of the housing 18. A bracket 19 is fixedly connected to the surface of the side wall of the housing 18 opposite to the storage box 14. Cleaning pads 26 are adhesively connected to the inner walls of a plurality of jacks on the side of the housing 18 opposite to the bracket 19. Branch pipes 28 are fixedly connected to the inside of the housing 18 on both sides of the jacks. A plurality of sprinkler heads 29 are installed on the surfaces of the side walls of the two branch pipes 28 close to each other;

[0033] The recycling component 11 includes a cover body 20 and a water tank 23. Ear plates are fixedly connected to the front and rear side wall surfaces of the cover body 20. A pin rod 21 is inserted into the ear plates. A drain pipe 22 communicates with the bottom of the cover body 20. The water tank 23 is arranged at one side position of the base 1. The bottom of the drain pipe 22 is located above the water tank 23. A filter element 25 is fixedly connected inside the water tank 23. A first rotating door 12 and a second rotating door 13 are hinged to the surface of one side wall of the water tank 23. The first rotating door 12 and the second rotating door 13 are respectively located above and below the filter element 25.

[0034] As Figures 1 - 4 shown, a push plate 24 is arranged on the upper side of the inner wall of the bottom of the water tank 23 and on the upper side of the filter element 25. A connecting rod is fixedly connected between the two push plates 24. The connecting rod is slidably connected to the side wall of the water tank 23.

[0035] During the use of traditional coal mine roadway drills, the water inside the drill holes directly flows onto the ground of the roadway, forming puddles or flowing everywhere, which brings certain troubles to the surrounding operating machines and the staff placing drill pipes. Moreover, this part of the water cannot be effectively utilized, resulting in waste. In this device, the user can set a cover body 20 outside the drill hole and fix it with the pin rod 21. Then, the water flowing out of the drill hole will flow along the drain pipe 22 into the water tank 23, instead of being directly discharged onto the ground of the roadway, thus avoiding troubles for the workers during work. After that, the filter element 25 will filter the sewage, facilitating the reuse of the filtered water later. When the water tank 23 has been used for a period of time, more sediment, coal blocks, etc. will accumulate on the filter element 25, and some impurities will also accumulate at the bottom of the water tank 23 due to the precipitation of water. At this time, the user can open the first rotating door 12 and the second rotating door 13 and push the connecting rod, so that the two push plates 24 will push away the impurities on them. This structural design makes the cleaning of the water tank 23 more convenient and conducive to use. In addition, in the structure, the filter element 25 filters out large-particle impurities, effectively purifying the water entering the lower part. Since the nozzle 29 is used to wash the drill pipe, its aperture is relatively large. Moreover, since the nozzle 29 extracts the upper-layer water after precipitation, the situation of the nozzle 29 being blocked will not occur.

[0036] As Figures 1 - 4 shown, a water outlet pipe is connected to the side wall of the water tank 23 below the filter element 25. A hose is installed at the end of the water outlet pipe. One end of the two branch pipes 28 penetrates through the housing 18 and is connected to a connector 27. The end of the hose is connected to the connector 27.

[0037] After the drilling is completed and the drill pipe is retrieved, when the surface of the drill pipe contacts the coal seam or rock stratum, more impurities are likely to adhere to its surface. Currently, the equipment is not convenient for quickly cleaning the surface when the worker puts it back on the storage rack 17. In this device, the user can start the driving motor to drive the threaded rod 15 to rotate, and then the moving part 16 drives one side of a certain layer of the storage rack 17 to reach the height of the bracket 19. Then the worker can push the disassembled drill pipe along the bracket 19 into the housing 18. At this time, the pump body is turned on to pump the water in the water tank 23 into the branch pipe 28 to supply water to the nozzle 29. The nozzle 29 will clean the impurities such as sediment on the surface of the drill pipe. After that, the water on the drill pipe will enter the storage rack 17 after being wiped off by the cleaning pad 26. This structural design enables the worker to quickly clean the surface of the drill pipe when putting it back, preventing the storage box 14, the storage rack 17, and the surface of the drill pipe from being seriously soiled.

[0038] As Figures 1 - 4 shown, threaded rods 15 are rotatably connected to the front and rear side walls of the storage box 14. A moving part 16 is threadedly connected to the surface of the threaded rod 15. The moving part 16 is fixedly connected to the adjacent connecting part. The connecting part is slidably connected to the storage box 14. The side wall of the storage box 14 is fixedly connected to a driving motor through a support plate. The output end of the driving motor is fixedly connected to the top of the threaded rod 15.

[0039] The driving motor can drive the threaded rod 15 to rotate, and then the moving part 16 drives the storage rack 17 to move up and down, thus facilitating the worker to store or retrieve the drill pipe.

[0040] As Figures 1 - 4 shown, bottom hydraulic rods 7 are fixedly connected to the four corner positions of the base 1. Top hydraulic rods 6 are fixedly connected to the front and rear edge positions of the top of the base 1. Pressing plates are fixedly connected to the top of the top hydraulic rods 6 and the bottom of the bottom hydraulic rods 7.

[0041] Before the drill works, the bottom hydraulic rods 7 and the top hydraulic rods 6 can be started to make the pressing plates at their ends respectively support on the surfaces of the bottom and top of the roadway, thereby preventing the drill from moving during the drilling process.

[0042] As Figures 1 - 4 shown, an installation part 2 is arranged on the upper side of the base 1. Angle adjustment cylinders 8 are hinged between the four corners of the installation part 2 and the top of the base 1. A sliding seat 3 is slidably connected to the top of the installation part 2. A power head 5 is fixedly connected to the top of the sliding seat 3. Clamps 9 are fixedly connected to the left and right side walls of the installation part 2 through fixing plates. A control motor is fixedly connected to the side wall of the installation part 2. The output end of the control motor is fixedly connected to a lead screw 4. The end of the lead screw 4 is rotatably connected to the installation part 2. The lead screw 4 is threadedly connected to the sliding seat 3.

[0043] Since the top of the angle-adjusting oil cylinder 8 is hinged to the mounting member 2 and its bottom is hinged to the base 1, the angle-adjusting oil cylinders 8 at the four corners of the mounting member 2 can control the lifting or pitching angle change of the mounting member 2. When it is necessary to adjust the front end of the mounting member 2 to tilt up, the two angle-adjusting oil cylinders 8 at the front end can be started to extend until the drill bit can be aligned with the designated position to be drilled. When the overall horizontal lifting of the mounting member 2 is required, controlling the four angle-adjusting oil cylinders 8 to start simultaneously can complete it. The gripper 9 and the power head 5 in the structure are both main equipment on the coal mine drill. The gripper 9 is a structure for fixing and clamping the drill pipe when necessary. The gripper 9 in this structure is a common gripper for coal mine machinery on the market, that is, one side is a fixed end and the other side is a movable end driven by an oil cylinder. When fixing the drill pipe, the movable end is pushed by the oil cylinder to clamp the surface of the drill pipe on the fixed end. The power head 5 will provide power for the drill pipe to make the drill bit rotate.

[0044] As Figures 1 - 4 shown, the power head 5 is fixedly connected with a drill pipe, and a plurality of drill pipes are provided and fixedly connected between adjacent two. Through holes are formed on the surface of the cover body 20, and one end of the drill pipe extends into the through holes.

[0045] A suitable drill bit can be installed at the end of the drill pipe. By fixing the cover body 20 on the drilling surface outside the drill pipe, the sewage flowing out of the drill hole can be intercepted to a certain extent, thereby avoiding serious water accumulation on the ground of the coal mine roadway.

[0046] The working principle of a coal mine roadway drilling device provided by the present utility model is as follows:

[0047] The first step: During the use of traditional coal mine roadway drills, the water inside the drill hole directly flows onto the ground of the roadway, forming puddles or flowing everywhere, which brings certain troubles to the surrounding operating machines and the staff placing drill pipes. Moreover, this part of the water cannot be effectively utilized, resulting in waste. In this device, the user can set a cover body 20 outside the drill hole and fix it with a pin rod 21. After that, the water flowing out of the drill hole will flow along the drain pipe 22 into the water tank 23, rather than being directly discharged onto the ground of the roadway, thus avoiding troubles for the workers during work. Then, the filter element 25 will filter the sewage, facilitating the reuse of the filtered water later. After the water tank 23 has been used for a period of time, more sediment, coal blocks, etc. will accumulate on the filter element 25, and some impurities will also accumulate at the bottom of the water tank 23 due to the precipitation of water. At this time, the user can open the first rotating door 12 and the second rotating door 13 and push the connecting rod, so that the two push plates 24 will push away the impurities on them. This structural design makes the cleaning of the water tank 23 more convenient and conducive to use. In addition, in the structure, the filter element 25 filters out large-particle impurities, effectively purifying the water entering the lower part. Since the nozzle 29 is used to wash the drill pipe, its aperture is relatively large. Moreover, since the nozzle 29 extracts the upper-layer water after precipitation, the situation of the nozzle 29 being blocked will not occur;

[0048] The second step: After the drilling is completed and the drill pipe is retracted, when the surface of the drill pipe contacts the coal seam or rock stratum, more impurities are likely to adhere to its surface. The current equipment is not convenient for quickly cleaning the surface when the worker puts it back on the placement rack 17. In this device, the user can start the driving motor to drive the threaded rod 15 to rotate, thereby making the movable part 16 drive a certain layer of the placement rack 17 on one side to reach the height of the bracket 19. Then the worker can push the disassembled drill pipe along the bracket 19 into the housing 18. At this time, turn on the pump body to pump the water in the water tank 23 into the branch pipe 28 to supply water to the nozzle 29. The nozzle 29 will wash the sediment and other impurities on the surface of the drill pipe. After that, the water on the drill pipe will enter the placement rack 17 after being wiped off by the cleaning pad 26. This structural design enables the worker to quickly clean the surface of the drill pipe when putting it back again, preventing the storage box 14, the placement rack 17, and the surface of the drill pipe from being seriously soiled.
