Description

Technical Field

[0001] The present invention relates to the technical field of mountain drilling, and specifically to a drilling rig device for mountain construction. Background Art

[0002] During geological exploration, it is often necessary to drill the ground or mountains. In this process, a drilling rig is required. In the related art, the working mode of the drilling rig is usually: the driving device transmits power to the drill tool through the transmission structure, and the drill bit at the lower part of the drill tool drills into the mountain. During the drilling process, the drill cuttings generated enter the inside of the drill pipe through the holes or side holes on the drill pipe, and then are discharged to the ground through the hollow channel of the drill pipe. During the drilling process of the drill bit, the degree of fragmentation of the mountain is affected by the hardness of the mountain. When the hardness of the mountain is relatively low, the mountain will form larger particles of debris. When the hardness of the mountain is relatively high, the debris formed by the mountain is smaller. However, since the size of the holes on the drill pipe is fixed, when the debris size is large, the debris is likely to block the holes, making it impossible to discharge the debris in time, which will in turn cause the drill bit to be stuck and affect the drilling efficiency of the rig; and during the use of the rig, sometimes drill pipe connection and disconnection are required. Currently, usually only the gripper is used to clamp the drill pipe. Once the gripper loosens, a drill pipe collapse accident will occur, making the drill pipe connection and disconnection process highly dangerous; and to ensure the stability of the rig during use, telescopic legs are usually provided around the moving base of the rig. The extension and retraction of the legs are usually controlled by hydraulic cylinders. However, due to the large amount of dust at the drilling site, the dust generated during drilling is likely to damage the hydraulic cylinders. Based on this, the present application proposes a drilling rig device for mountain construction. Summary of the Invention

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] The present invention provides a drilling rig device for mountain construction, including a mobile base 1. The mobile base 1 is a wheeled walking mechanism in the prior art and will not be elaborated here. A hydraulic cylinder 1 3 is fixedly connected to the outside of the wheels of the mobile base 1. The end of the output shaft of the hydraulic cylinder 1 3 is movably connected to a stabilizing wheel 2. The outer diameter of the stabilizing wheel 2 is the same as that of the wheels of the mobile base 1, and the outer surface of the stabilizing wheel 2 is wrapped with an anti-wear pad, and the material of the anti-wear pad can be rubber. Through the setting of the hydraulic cylinder 1 3, the telescopic movement of the hydraulic cylinder 1 3 can change the position of the stabilizing wheel 2. During the walking process of the device, the stabilizing wheel 2 can closely adhere to the wheels of the mobile base 1, reducing the drilling area of the device and improving the stability of the device during movement. When the device is drilling, the stabilizing wheel 2 can move away from the wheels of the mobile base 1 to support the device, reducing the probability of the device tipping over. Moreover, the hydraulic cylinder 1 3 is protected by a telescopic sleeve 4. One end of the telescopic sleeve 4 is movably connected to the stabilizing wheel 2, and the other end of the telescopic sleeve 4 is fixedly connected to the wheels of the mobile base 1. The hydraulic cylinder 1 3 is located inside the cavity of the telescopic sleeve 4. Through the setting of the telescopic sleeve 4, it can prevent dust during the drilling process from adhering to the hydraulic cylinder 1 3, facilitating the telescopic movement of the hydraulic cylinder 1 3.

[0029] A drilling structure is arranged on one side of the mobile base 1. The drilling structure includes a rotating rod 14. One end of the rotating rod 14 is movably connected to the mobile base 1. The rotating rod 14 is fixedly connected to the mobile base 1 through a servo motor 2. The other end of the rotating rod 14 is movably connected to a support frame 5. The support frame 5 is fixedly connected to the rotating rod 14 through a servo motor 1. Through the setting of the rotating rod 14, the angle between the support frame 5 and the rotating rod 14 can be changed, and the distance between the support frame 5 and the mobile base 1 can be changed.

[0030] A lifting structure 13 is arranged on the top of the support frame 5. The bottom of the lifting structure 13 is connected with a driving device. The lifting structure 13 can change the height of the driving device. Guide rods are fixedly connected to both sides of the support frame 5. The driving device is movably connected to the guide rods, and the guide rods can limit the driving device.

[0031] The bottom of the driving device is connected to a drill pipe 11 through a transmission structure 25. The bottom of the drill pipe 11 is connected to a drill bit 12. The top of the transmission structure 25 is movably sleeved with a slag discharge ring 6. The drill pipe 11, the transmission structure 25, and the slag discharge ring 6 are all hollow structures. One side of the inner cavity of the slag discharge ring 6 is provided with a slag discharge pipe 7. The side walls of the drill pipe 11, the transmission structure 25, and the slag discharge ring 6 are all hollow structures, and both ends of the side walls of the drill pipe 11, the transmission structure 25, and the slag discharge ring 6 are fixedly connected with water-permeable nets 27. One side of the inner cavity of the side wall of the slag discharge ring 6 is fixedly connected with a high-pressure water pipe 26. Through the above description, when the transmission structure 25, the drill pipe 11, and the drill bit 12 are connected, the inner cavities around the slag discharge ring 6, the transmission structure 25, the drill pipe 11, and the drill bit 12 are in a connected state, which is convenient for the discharge of debris during the drilling process. The inner cavities of the side walls around the slag discharge ring 6, the transmission structure 25, the drill pipe 11, and the drill bit 12 are in a connected state, and high-pressure water can enter the inner cavity of the side wall of the drill bit 12.

[0032] The top end of the drill bit 12 is a hollow structure. The side wall of the top end of the drill bit 12 is provided with a liquid discharge hole 23 and a slag discharge side hole 20. High-pressure water can be discharged to the periphery of the drill bit 12 through the liquid discharge hole 23, which is convenient for chip removal. The slag discharge side hole 20 is connected to the inner cavity of the top end of the drill bit 12. Debris can enter the inner cavity of the drill bit 12 through the slag discharge side hole 20. A hammering hole is provided at the top of the slag discharge side hole 20. A hammer 21 is connected to the inner cavity of the hammering hole through a first spring 24. Under the impact of high-pressure water, the hammer 21 can hammer the debris in the slag discharge side hole 20, reducing the size of the debris, improving the chip removal smoothness, and preventing the drilling rig from being stuck. The top end of the inner cavity of the hammering hole is movably connected with a first filter net. The bottom of the first filter net is fixedly connected to the hammering hole through a second spring. A second filter net 22 is fixedly connected to the top of the inner cavity of the hammering hole. An electromagnet is fixed on the second filter net 22. When the electromagnet is in an energized state, the electromagnet and the first filter net are magnetically attracted to each other. The structures of the first filter net and the second filter net 22 are the same, and the mesh holes on the first filter net and the mesh holes on the second filter net 22 are in a staggered state. Through the setting of the first filter net and the second filter net 22, when the electromagnet is in an energized state, the electromagnet and the first filter net are magnetically attracted to each other. Under the action of this suction force, the first filter net and the second filter net 22 are closely fitted, and the first filter net and the second filter net 22 can block the hammering hole. Under the action of the restoring force of the first spring 24, the hammer 21 can be reset, which is convenient for the use of the hammer 21. When the electromagnet is in a de-energized state, under the action of the restoring force of the first spring 24, the hammer 21 can be reset.

[0033] The top end of the hammer 21 has a clearance fit with the hammering hole. The bottom of the hammer 21 can block the hammering hole. A filter felt is fixedly connected to the bottom of the hammering hole. A through hole adapted to the hammer 21 is provided in the middle of the filter felt. Through the setting of the filter felt, debris can be intercepted to prevent debris from entering the inner cavity of the hammering hole.

[0034] The drill pipe support structure includes a lifting and translation structure connected to the mobile base 1, a lifting rod 8 connected to the lifting and translation structure, a support plate 10 fixedly connected to the bottom of the lifting rod 8, a translation rod 28 connected to the top of the support plate 10 through a second hydraulic cylinder 9, a first limiting plate 17 fixedly connected to the top of the translation rod 28, and a second limiting plate 19 movably connected to the first limiting plate 17. The first limiting plate 17 and the second limiting plate 19 form a trumpet-shaped limiting sleeve. The inner diameter of the bottom end of the limiting sleeve is adapted to the outer diameter of the drill pipe, and the outer diameter of the top end of the limiting sleeve is larger than its bottom end outer diameter, facilitating the drill pipe to be placed into the limiting sleeve. The second hydraulic cylinder 9 is protected through a telescopic sleeve 4.

[0035] The lifting and translation structure includes a third hydraulic cylinder 15 fixedly connected to the mobile base 1. The end of the output shaft of the third hydraulic cylinder 15 is fixedly connected with a fourth hydraulic cylinder 16. Both the third hydraulic cylinder 15 and the fourth hydraulic cylinder 16 are protected through another telescopic sleeve 4. Through the setting of the lifting and translation structure, the height and horizontal position of the support plate 10 can both be changed. When the device is in use, the drill pipe support structure can support the drill pipe to prevent the drill pipe from falling. Moreover, when the drill pipe is disassembled and connected, the top of the support plate 10 can be at the same height as the top of the drill pipe located in the mountain body. A groove is provided on one side of the support plate 10 close to the drilling structure, and the inner diameter of the groove is the same as the outer diameter of the drill pipe. Through the setting of the groove, the support plate 10 can be closely fitted with the drill pipe, and the telescopic movement of the second hydraulic cylinder 9 can change the position of the limiting sleeve, and the limiting sleeve drives the drill pipe to move, facilitating the connection of a new drill pipe with the drill pipe located in the mountain body.

[0036] One side of the bottom end of the first limiting plate 17 is fixedly connected with a first servo motor 18. The end of the output shaft of the first servo motor 18 is fixedly connected with a rotating shaft through a reducer, and the rotating shaft is fixedly connected with the second limiting plate 19. The inner diameters of the bottom ends of both the first limiting plate 17 and the second limiting plate 19 are adapted to the outer diameter of the drill pipe, and the outer diameters of the top ends of both the first limiting plate 17 and the second limiting plate 19 are larger than their bottom end outer diameters. Through the setting of the first servo motor 18, the rotation of the first servo motor 18 can drive the second limiting plate 19 to rotate, and the second limiting plate 19 can be separated from the first limiting plate 17, facilitating the separation of the limiting sleeve from the drill pipe.

[0037] The electrical components involved in this application are all prior art, and those skilled in the art understand their connection methods. Through those skilled in the art, all the electrical components in this application are connected to their adapted power supplies through wires, and a suitable controller is selected according to the actual situation to meet the control requirements. For the specific connection and control sequence, refer to the following description. The electrical connection is completed for the sequential operation of each electrical component. Its detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and no further description of the electrical control will be made.

[0038] In summary, when the drilling rig device for mountain construction is in use, when the moving base 1 moves to a suitable position, the first hydraulic cylinder 3 extends to increase the distance between the stabilizing wheel 2 and the wheels of the moving base 1, improving the stability of the device. The lifting structure 13 changes the height of the drill bit 12, and the driving device drives the drill bit 12 to rotate through the transmission structure. The drill bit 12 can drill the mountain body. During the drilling process, the flushing water enters the drainage hole 23 through the high-pressure water pipe 26 and is discharged around the drill bit 12 through the drainage hole 23. After the debris is mixed with the flushing water, it enters the inner cavity of the drill tool through the slag discharge side hole 20 and is finally discharged through the slag discharge pipe 7. During the slag discharge process, the hammer 21 strikes the debris to reduce the volume of the debris, facilitating the blockage of the slag discharge side hole by the debris. When it is necessary to connect or disconnect the drill pipe, the gripper holds the drill pipe until the drill pipe is placed in the limiting sleeve. The bottom of the drill pipe contacts the top of the support plate 10. The limiting sleeve limits the drill pipe, and the support plate 10 supports the drill pipe, avoiding the phenomenon of the drill pipe falling. After the driving device is separated from the drill pipe located in the mountain body, the second servo motor and the third servo motor work. The combined use of the second servo motor and the third servo motor causes the driving device to move away. Under the action of the lifting and translation structure, the support plate 10 drives the drill pipe to approach the drill pipe located in the mountain body until the support plate 10 is closely attached to the drill pipe located in the mountain body. The second hydraulic cylinder 9 drives the limiting sleeve to move, and the gripper drives the drill pipe to move. The combined use of the limiting sleeve and the gripper enables the new drill pipe to contact the drill pipe located in the mountain body, facilitating the connection of the two drill pipes. After the new drill pipe is connected, the first servo motor 18 drives the second limiting plate 19 to rotate until the second limiting plate 19 and the first limiting plate 17 are located on the side of the drill pipe close to the support plate 10. The lifting and translation structure drives the support plate 10 to reset, and the driving device can be reconnected to the drill pipe.
