Description

Technical Field

[0001] This utility model relates to the field of drilling rigs, and in particular to a drilling device with automatically adjustable depth. Background Technology

[0002] A drilling rig is a piece of equipment used for drilling wells. It is widely used in the exploration and development of resources such as oil, natural gas, and geothermal energy. Drilling rigs can be divided into forward circulation drilling rigs and reverse circulation drilling rigs according to different geological conditions and operational requirements.

[0003] Existing deep drilling equipment does not have a drill bit cleaning function during use, and cannot clean the outer surface of the drill bit. When the drill bit is removed after drilling, a large amount of silt will be attached to the outer surface of the drill bit, which makes cleaning time-consuming and laborious.

[0004] Therefore, to address the problem that existing deep drilling devices lack a drill bit cleaning function during use, resulting in a large amount of silt adhering to the outer surface of the drill bit after drilling and its removal, making cleaning difficult, an automatically adjustable depth drilling device can be designed. By incorporating a second drive motor, its output end will drive a gear to rotate during operation. When the gear rotates, it can drive a rotating ring to rotate synchronously on the upper surface of the limit seat in cooperation with the meshing teeth. The rotation of the rotating ring can drive the sponge ring to rotate, thereby cleaning the outer surface of the drill bit during the removal process and reducing the adhesion of silt on the outer surface of the drill bit.

Two sets of symmetrical support components are provided on the upper surface of the bottom support. A drive component is provided at the front position of the upper surface of the bottom support. A transmission module is connected to the moving end of the drive component, and a drill bit is connected to the output end of the transmission module. A limiting seat is installed on the front surface of the bottom support, and a rotating ring is slidably connected to the upper surface of the limiting seat. Several meshing teeth in a circumferential array are provided on the upper part of the outer surface of the rotating ring, and a sponge ring is provided on the inner surface of the rotating ring. A support plate is installed at the front position of the bottom surface of the limiting seat, and a second drive motor is installed on the upper surface of the support plate. A gear is connected to the output end of the second drive motor, and the gear meshes with the meshing teeth.

[0007] Preferably, by setting a second drive motor, its output end will drive the gear to rotate during operation. When the gear rotates, it can drive the rotating ring to rotate synchronously on the upper surface of the limit seat in cooperation with the meshing teeth. When the rotating ring rotates, it can drive the sponge ring to rotate, thereby cleaning the outer surface of the drill bit during the removal of the drill bit, reducing the adhesion of silt on the outer surface of the drill bit. This solves the problem that existing deep drilling devices do not have a drill bit cleaning function during use, and when the drill bit is removed after drilling, a large amount of silt will be attached to the outer surface of the drill bit, which is difficult to clean.

[0008] Preferably, the support assembly includes a sleeve, a telescopic rod, a sleeve base, and a support leg; the upper surface of the bottom bracket is provided with two symmetrical sleeves, the inside of which a telescopic rod is slidably inserted and connected, the end of the telescopic rod away from the corresponding sleeve is connected to a sleeve base, and the inner surface of the sleeve base is slidably connected to a support leg.

[0011] Preferably, the support assembly also includes washers and pins; washers are installed on the bottom surface of the outriggers, and pins are installed at the corners of the bottom surface of the washers.

[0012] Preferably, the drive assembly includes a movable frame, a first drive motor, a screw, and a movable base; the movable frame is installed on the left side of the front side of the upper surface of the bottom bracket, the first drive motor is installed on the top surface of the movable frame, the output end of the first drive motor passes through the top surface of the movable frame and is connected to one end of the screw, the other end of the screw is rotatably connected to the bottom of the inner surface of the movable frame, the outer surface of the screw is threadedly connected to the movable base, and the front surface of the movable base is connected to the rear surface of the transmission module.

[0013] Preferably, the drive assembly also includes a connecting rod, a limiting frame, a limiting block, and a limiting rod; the right side surface of the moving frame is provided with one end of two symmetrical connecting rods, the other end of the connecting rods is connected to the limiting frame, the bottom surface of the limiting frame is connected to the upper surface of the bottom bracket, the inner surface of the limiting frame is connected to the upper and lower sides of the limiting rod, the outer surface of the limiting rod is slidably connected to the limiting block, and the front surface of the limiting block is connected to the rear surface of the transmission module.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting a second drive motor, its output end will drive the gear to rotate during operation. When the gear rotates, it can drive the rotating ring to rotate synchronously with the meshing teeth. The setting of the limit seat can limit the bottom of the rotating ring to prevent the rotating ring from loosening. When the rotating ring rotates, it can drive the sponge ring to rotate. Thus, when the drill bit is removed, the sponge ring is in contact with the drill bit and rotates, which can clean the outer surface of the drill bit and reduce the adhesion of silt on the outer surface of the drill bit. This solves the problem that the existing deep drilling equipment does not have the function of cleaning the drill bit during use, and when the drill bit is removed after drilling, a lot of silt will be attached to the outer surface of the drill bit, which is difficult to clean.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4This utility model provides an embodiment of an automatically adjustable depth drilling device, including a bottom support 1; it also includes a limiting seat 8, a rotating ring 9, meshing teeth 10, a sponge ring 11, a support plate 12, a second drive motor 13, and a gear 14. Two symmetrical mounting seats 2 are provided on the rear surface of the bottom support 1, and wheels 3 are rotatably connected to the outer sides of both mounting seats 2. Two sets of symmetrical support components are provided on the upper surface of the bottom support 1. A drive component is provided at the front position of the upper surface of the bottom support 1. The moving end of the drive component is connected to a transmission module 6, and the output end of the transmission module 6 is connected to a drill bit 7. A limiting seat 8 is installed on the front surface of the bottom support 1, and a rotating ring 9 is slidably connected to the upper surface of the limiting seat 8. A gear 14 is provided on the upper part of the outer surface of the rotating ring 9. The circular array has several meshing teeth 10. A sponge ring 11 is provided on the inner surface of the rotating ring 9. A support plate 12 is installed at the front position of the bottom surface of the limiting seat 8. A second drive motor 13 is installed on the upper surface of the support plate 12. The output end of the second drive motor 13 is connected to a gear 14. The gear 14 meshes with the meshing teeth 10. By setting the second drive motor 13, its output end will drive the gear 14 to rotate during operation. When the gear 14 rotates, it can drive the rotating ring 9 to rotate synchronously on the upper surface of the limiting seat 8 in cooperation with the meshing teeth 10. When the rotating ring 9 rotates, it can drive the sponge ring 11 to rotate. Thus, during the process of moving the drill bit 7 upward and taking it out, the outer surface of the drill bit 7 can be cleaned, reducing the adhesion of sludge on the outer surface of the drill bit 7.

[0023] Please see Figures 1-3 In this embodiment, the support assembly includes a sleeve 41, a telescopic rod 42, a base 43, and a support leg 44. Two symmetrical sleeves 41 are provided on the upper surface of the bottom bracket 1. A telescopic rod 42 is slidably inserted into the inside of each sleeve 41. The end of the telescopic rod 42 away from the corresponding sleeve 41 is connected to a base 43. The support leg 44 is slidably connected to the inner surface of the base 43. By providing the sleeves 41 and the telescopic rod 42, the length of the support structure can be adjusted. The base 43 and the support leg 44 facilitate the adjustment of the height of the support structure, thereby ensuring that the entire device is in a horizontal state during use, thus improving stability. The support assembly also includes fixing bolts 45; fixing bolts 45 are connected to the front position of the upper surface of the sleeve 41 and the front side surface of the sleeve base 43. By setting fixing bolts 45, after the position adjustment of the telescopic rod 42 and the outrigger 44 is completed, the position of the two can be fixed by tightening the fixing bolts 45 to prevent loosening. The support assembly also includes sliders 46; sliders 46 are set on both the left and right sides of the outer surface of the outrigger 44. The telescopic rod 42 is slidably connected to the sleeve base 43 through the sliders 46. By setting sliders 46, the outrigger 44 can be assisted to slide, improving the accuracy and stability of the outrigger 44 when adjusting its position.

[0024] Please see Figures 1-4In this embodiment, the support assembly also includes a shim 47 and a pin 48. A shim 47 is installed on the bottom surface of the support leg 44, and pins 48 are installed at the corners of the bottom surface of the shim 47. By setting the shim 47 and pins 48, after adjusting the position of the support assembly, the pins 48 can be inserted into the working ground to assist in positioning the entire device. The drive assembly includes a moving frame 51, a first drive motor 52, a screw 53, and a moving seat 54. A moving frame 51 is installed on the upper surface of the bottom support 1, on the left side. A first drive motor 52 is installed on the top surface of the moving frame 51. The output end of the first drive motor 52 passes through the top surface of the moving frame 51 and is connected to one end of the screw 53. The other end of the screw 53 is rotatably connected to the bottom of the inner surface of the moving frame 51. A moving seat 54 is threaded through the outer surface of the screw 53. The front surface of the moving seat 54 is connected to the rear surface of the transmission module 6. By setting the first drive motor 52, its output end will drive the device during operation. The screw 53 rotates, which drives the moving seat 54, which is threaded to it, to move up and down. This causes the transmission module 6 to move the drill bit 7, thereby controlling the drilling depth. The drive assembly also includes a connecting rod 55, a limiting frame 56, a limiting block 57, and a limiting rod 58. The right side surface of the moving frame 51 is provided with one end of two symmetrical connecting rods 55. The other end of the connecting rods 55 is connected to the limiting frame 56. The bottom surface of the limiting frame 56 is connected to the upper surface of the bottom support 1. The inner surface of the limiting frame 56 is connected to the upper and lower sides of the limiting rod 58. The outer surface of the limiting rod 58 is slidably connected to the limiting block 57. The front surface of the limiting block 57 is connected to the rear surface of the transmission module 6. By setting the limiting block 57 and the limiting rod 58, when the transmission module 6 moves, it can drive the limiting block 57 to slide synchronously on the outer surface of the limiting rod 58. The limiting rod 58 can limit the sliding direction of the limiting block 57, thereby improving the stability of the transmission module 6 when it moves.

[0025] During operation, the length of the support structure can be adjusted by using sleeve 41 and telescopic rod 42. The sleeve base 43 and outrigger 44 facilitate height adjustment of the support structure, ensuring the equipment remains level during use and improving stability. After adjusting the positions of the telescopic rod 42 and outrigger 44, the fixing bolts 45 can be tightened to secure them and prevent loosening. The slider 46 assists in the sliding of the outrigger 44, improving the accuracy and stability of its position adjustment. The shim 47 and pin 48 ensure the support assembly is properly adjusted. After positioning, pin 48 can be inserted into the working ground to assist in positioning the entire device. By setting the first drive motor 52, its output end will drive the screw 53 to rotate during operation. When the screw 53 rotates, it can drive the moving seat 54 that is threaded with it to move up and down, thereby causing the transmission module 6 to drive the drill bit 7 to move, thereby controlling the drilling depth. By setting the limit block 57 and the limit rod 58, when the transmission module 6 moves, it can drive the limit block 57 to slide synchronously on the outer surface of the limit rod 58. The limit rod 58 can limit the sliding direction of the limit block 57, thereby improving the stability of the transmission module 6 when moving.

[0026] Through the above steps, by setting the second drive motor 13, its output end will drive the gear 14 to rotate during operation. When the gear 14 rotates, it can drive the rotating ring 9 to rotate synchronously in cooperation with the meshing teeth 10. The setting of the limit seat 8 can limit the bottom of the rotating ring 9 to prevent the rotating ring 9 from loosening. When the rotating ring 9 rotates, it can drive the sponge ring 11 to rotate. Thus, during the process of moving the drill bit 7 upward and taking it out, the sponge ring 11 is in contact with the drill bit 7 and rotates, which can clean the outer surface of the drill bit 7 and reduce the sludge adhesion on the outer surface of the drill bit 7. This solves the problem that the existing deep drilling equipment does not have the function of cleaning the drill bit 7 during use, and when the drill bit 7 is taken out after drilling, a lot of sludge will be attached to the outer surface of the drill bit 7, which is difficult to clean.
