Description

Technical Field

[0001] The invention relates to the technical field of mountain drilling, in particular to a drilling machine device used for mountain construction. Background Art

[0002] In geological surveys, it is often necessary to drill the ground or mountains, and in this process, a perforating drill is needed. In the relevant technology, the working mode of the perforating drill is usually: the driving device transmits power to the drill tool through the transmission structure, and the drill bit at the bottom of the drill tool drills the mountain. The drill cuttings generated during the drilling process enter the drill rod through the holes or side holes on the drill rod, and then are discharged to the ground through the hollow channel of the drill rod. When the drill bit is drilling, the degree of mountain fragmentation is affected by the hardness of the mountain. When the hardness of the mountain is relatively low, the mountain will form larger 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 rod is fixed, when the debris size is large, the debris is easy to block the hole, so that the debris cannot be discharged in time, which will cause the drill bit to be stuck, affecting the drilling efficiency of the drilling rig; and during the use of the drilling rig, it is sometimes necessary to connect and unconnect the drill rod. At present, the drill rod is usually clamped only by a clamp. Once the clamp is loose, the drill rod collapse accident will occur, making the drill rod connection and unloading process highly dangerous; and in order to ensure the stability of the drilling rig during use, telescopic legs are generally provided around the mobile base of the drilling rig. The extension and storage of the legs are usually controlled by a cylinder, but due to the large amount of dust at the drilling site, the dust generated by drilling can easily cause damage to the cylinder; Based on this, the present application proposes a drilling rig device for mountain construction.

The limit plate 17 and the limit plate 29 form a trumpet-shaped limit sleeve, the inner diameter of the bottom end of the limit sleeve is adapted to the outer diameter of the drill pipe, and the outer diameter of the top end of the limit sleeve is larger than the outer diameter of the bottom end, so that the drill pipe can be placed in the limit sleeve. The hydraulic cylinder 29 is protected by a telescopic sleeve 4.

[0035] The lifting and translation structure includes a hydraulic cylinder three 15 fixedly connected to the mobile base 1, and the end of the output shaft of the hydraulic cylinder three 15 is fixedly connected to a hydraulic cylinder four 16; the hydraulic cylinder three 15 and the hydraulic cylinder four 16 are both protected by another telescopic sleeve 4. Through the setting of the lifting and translation structure, the height and horizontal position of the support plate 10 can be changed. When the device is in use, the drill rod support structure can support the drill rod to prevent the drill rod from falling, and when the drill rod is disassembled, the top of the support plate 10 can be at the same height as the top of the drill rod located in the mountain. A groove is provided on the 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 rod. Through the setting of the groove, the support plate 10 can fit tightly with the drill rod, and the telescopic movement of the hydraulic cylinder two 9 can change the position of the limit sleeve, and the limit sleeve drives the drill rod to move, which is convenient for the new drill rod to be connected with the drill rod located in the mountain.

[0036] A servo motor 18 is fixedly connected to one side of the bottom end of the limit plate 17, and the end of the output shaft of the servo motor 18 is fixedly connected to a rotating shaft through a reducer, and the rotating shaft is fixedly connected to the limit plate 2 19; the inner diameters of the bottom ends of the limit plate 17 and the limit plate 2 19 are both adapted to the outer diameter of the drill pipe, and the outer diameters of the top ends of the limit plate 17 and the limit plate 2 19 are larger than the outer diameters of their bottom ends.

[0037] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods. Through these technicians, all the electrical components in this application are connected to their compatible power supplies through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0038] To sum up: when the drilling rig device for mountain construction is used, when the mobile base 1 moves to a suitable position, the hydraulic cylinder 3 extends, increasing the distance between the stabilizing wheel 2 and the wheel of the mobile base 1, thereby improving the stability of the device, and the lifting structure 13 changes the height of the drill bit 12. The driving device drives the drill bit 12 to rotate through the transmission structure, and the drill bit 12 can perform drilling operations on the mountain. In the drilling process, flushing water enters the drainage hole 23 through the high-pressure water pipe 26, and is discharged to the vicinity of the drill bit 12 through the drainage hole 23. The debris is mixed with the flushing water and 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. In the slag discharge process, the percussion hammer 21 strikes the debris to reduce the volume of the debris, thereby facilitating the debris to block the slag discharge side hole. When it is necessary to connect or disconnect the drill rod, the clamp clamps the drill rod until the drill rod is placed in the limiting sleeve, the bottom of the drill rod contacts the top of the support plate 10, the limiting sleeve limits the drill rod, and the support plate 10 supports the drill rod to avoid the drill rod falling. After the driving device is separated from the drill rod in the mountain, servo motor 2 and servo motor 3 work, and the coordinated use of servo motor 2 and servo motor 3 makes the driving device move away. Under the action of the lifting and translation structure, the support plate 10 drives the drill rod to approach the drill rod in the mountain. Until the support plate 10 is tightly fitted with the drill rod located in the mountain, the hydraulic cylinder 29 drives the limit sleeve to move, and the clamp drives the drill rod to move. The limit sleeve and the clamp are used in coordination so that the new drill rod can contact the drill rod located in the mountain, which is convenient for connecting the two drill rods. After the new drill rod is connected, the servo motor 18 drives the limit plate 2 19 to rotate until the limit plate 2 19 and the limit plate 17 are located on the side of the drill rod close to the support plate 10. The lifting and translation structure drives the support plate 10 to reset, and the drive device can be connected to the drill rod again.
