Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, specifically to a drilling device for processing the outer surface of a pipeline. Background Technology

[0002] A pipeline is a system of pipes, pipe fittings, valves, and other components used to transport gases, liquids, or fluids containing solid particles. Typically, fluids are pressurized by blowers, compressors, pumps, and boilers, flowing from high-pressure areas to low-pressure areas within the pipeline. Alternatively, the fluid's own pressure or gravity can be used for transport. Pipelines have a wide range of applications, primarily in water supply, drainage, heating, gas supply, long-distance transport of oil and natural gas, agricultural irrigation, water conservancy projects, and various industrial installations.

[0003] PE pipe is a widely used type of pipe. During the processing of PE pipe, it may be necessary to drill holes according to actual needs. There are often multiple drilling positions. On the same straight line, a moving drilling tool is often used to prevent the pipe from being clamped and fixed multiple times. Existing technology is not convenient for drilling positions on the same ring of the pipe, and it is necessary to fix it multiple times, which makes the drilling efficiency low and increases the time cost.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0025] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0026] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] like Figures 1-5 As shown, a drilling device for processing the outer surface of a pipe is illustrated in one embodiment of the present invention, comprising: a housing 1, a fixed housing 2 fixedly connected inside the housing 1, a feeding assembly 3 installed at the front end of the fixed housing 2, and a drilling assembly 8 installed on the top wall of the inner cavity of the housing 1; and an outer shell 4, a housing 4 fixedly connected to the left end of the housing 1, a driving assembly 5 installed at the left end of the housing 4, a support assembly 6 installed at the left end of the housing 1 and inside the housing 4, and a connecting assembly 7 installed inside the support assembly 6.

[0031] For example, such as Figure 5 As shown, the support assembly 6 includes a rotating plate 61. The rotating plate 61 is rotatably connected to the left end of the housing 1 and inside the outer shell 4. A cylinder 62 is fixedly connected to the left end of the rotating plate 61. The output end of the cylinder 62 extends into the interior of the housing 1 and is fixedly connected to a fixing block 63. A fixing plate 64 is fixedly connected to the fixing block 63. A connector 65 is rotatably connected to the front end of the fixing plate 64 via a fixing rod. A fixing plate 66 is rotatably connected to the upper end of the connector 65 via a fixing rod. An inner support block 67 is fixedly connected to the top end of the fixing plate 66. When the cylinder 62 is activated, the fixing block 63 moves to the right. The fixing block 63 causes the connector 65 to move under the constraint of the fixing rod. The connector 65, through the fixing plate 66 and the fixing plate, causes the inner support block 67 to move outward, fixing the pipe and facilitating subsequent drilling.

[0032] For example, such as Figure 5As shown, the connecting assembly 7 includes a sleeve 71. The sleeve 71 is fixedly connected to the right end of the rotating plate 61 and located outside the output end of the cylinder 62. A positioning plate 1 72 is fixedly connected to the sleeve 71. A connecting block 73 is rotatably connected to the front end of the positioning plate 1 72 through a fixing rod. A positioning plate 2 74 is rotatably connected to the upper end of the connecting block 73 through a fixing rod. The top end of the positioning plate 2 74 is fixedly connected to the inside of the support block 67. When the inner support block 67 moves, the connecting block 73 moves through the positioning plate and the fixing rod, further supporting the movement of the inner support block 67. In cooperation with the support assembly 6, it further ensures that the inner support block 67 can smoothly fix the pipeline.

[0033] For example, such as Figure 4 As shown, the drive assembly 5 includes a second servo motor 51. The second servo motor 51 is fixedly connected to the left end of the housing 4. The output end of the second servo motor 51 extends into the interior of the housing 4 and is fixedly mounted with a rotating rod 52. The right end of the rotating rod 52 is fixedly connected to a drive gear 53. The left end of the cylinder 62 is fixedly connected to a driven gear 54. The drive gear 53 and the driven gear 54 are meshed. When the second servo motor 51 is started, the drive gear 53 rotates through the rotating rod 52. The meshing of the drive gear 51 and the driven gear 54 causes the support assembly 6 to rotate. The support assembly 6 causes the rotating plate 61 to rotate inside the housing 1, thereby further driving the pipe to rotate, which facilitates drilling holes at different positions on the same ring of the pipe.

[0034] For example, such as Figure 2 As shown, a limit rod 15 is fixedly connected inside the box 1 and inside the fixed box 2. A feed inlet 14 is opened at the right end of the box 1. A through hole 9 is opened at the bottom end of the fixed box 2. A hopper 10 is fixedly connected to the bottom end of the fixed box 2. A dust collection pump 11 is fixedly connected to the bottom wall of the inner cavity of the box 1. The air inlet pipe of the dust collection pump 11 extends into the hopper 10. A dust collection box 12 is fixedly connected to the bottom wall of the inner cavity of the box 1 and to the right of the dust collection pump 11. The air outlet pipe of the dust collection pump 11 extends into the dust collection box 12. A filter screen 13 is fixedly connected to the right end of the box 1 and inside the dust collection box 12. When drilling, the dust collection pump 11 is started so that the particles left by drilling fall into the hopper 10 through the through hole 9, and then are sent into the dust collection box 12 by the dust collection pump 11. Finally, the air is discharged through the filter screen 13 to maintain the drilling environment and prevent dust from flying around.

[0035] In some examples, the pipe is inserted through the inlet 14 and fed using the limit rod 15 and the feeding assembly 3. When the pipe reaches the inside of the housing 1 near the left side, the support assembly 6 operates, activating the cylinder 62 to move the fixing block 63 to the right. The fixing block 63 then moves the fixing plate 64, which, under the constraint of the fixing rod, moves the connector 65. The connector 65, through the fixing plate 66 and the fixing plate, causes the inner support block 67 to move outward, fixing the pipe in place for subsequent drilling. The cylinder 62 is an MD-10X model with a single piston structure, providing high clamping torque and high piston rod guiding accuracy. Simultaneously, the connecting assembly 7 operates, and as the inner support block 67 moves, the positioning plate and fixing rod cause the connecting block 73 to move, further supporting the movement of the inner support block 67. This, in conjunction with the support assembly 6, further ensures that the inner support block 67 successfully fixes the pipe. After the drilling assembly 8 completes its operation, the drive assembly 5 operates, activating the servo motor. Machine 2 51 rotates the drive gear 53 via the rotating rod 52. The drive gear 51 meshes with the driven gear 54, causing the support assembly 6 to rotate. The support assembly 6 causes the rotating plate 61 to rotate inside the housing 1, thereby further driving the pipe to rotate. This facilitates drilling at different positions on the same ring of the pipe. By reasonably designing the number of teeth of the double gears, a large transmission ratio can be achieved, which can convert the high speed of the input shaft into the low speed of the output shaft, meeting the needs of low-speed, high-torque equipment. During drilling, the dust pump 11 is activated, causing the particles left after drilling to fall into the feed hopper 10 through the through hole 9. Then, the particles are sent to the dust collection box 12 by the dust pump 11. Finally, the air is discharged through the filter screen 13. The filter screen 13 is made of stainless steel, which has the advantages of high strength, strong corrosion resistance, and high temperature resistance. It can filter dust particles of different sizes, is easy to clean and maintain, maintains the drilling environment, and prevents dust from flying around.

[0036] like Figures 1-6 As shown, this invention illustrates a drilling device for processing the outer surface of a pipe in another embodiment. The feeding assembly 3 includes a support plate 31. The support plate 31 is fixedly connected to the front end of the fixed box 2. A servo motor 32 is fixedly connected to the top end of the support plate 31. The output end of the servo motor 32 extends to the lower side of the support plate 31 and is fixedly mounted with a rotating shaft 33. A drive wheel 34 is fixedly connected to the lower end of the rotating shaft 33. The rear end of the drive wheel 34 extends into the interior of the fixed box 2. When the servo motor 31 is started, it drives the rotating shaft 33 to rotate the drive wheel 34. The drive wheel 34 drives the pipe to move. The servo motor is equipped with a high-precision encoder, which can accurately feedback the rotor position and realize precise position control and speed control, making it convenient to control the feeding and feeding of the pipe.

[0037] For example, such as Figure 6As shown, the drilling assembly 8 includes an electric push rod 81. The electric push rod 81 is fixedly connected to the top wall of the inner cavity of the housing 1. The output end of the electric push rod 81 is fixedly connected to a support frame 82. The bottom wall of the inner cavity of the support frame 82 is fixedly connected to a drill 83. The output end of the drill 83 extends to the bottom of the support frame 82. When the electric push rod 81 is activated, the support frame 82 moves down, and the support frame 82 drives the drill 83 to drill holes in the surface of the pipe. In conjunction with the support assembly 6, the drill 83 can drill holes in different positions of the pipe, making drilling more convenient.

[0038] In some examples, the pipe is fed in through the inlet 14, the feeding assembly 3 operates, and the servo motor 31 is started, which drives the rotating shaft 33 to rotate the drive wheel 34. The drive wheel 34 moves the pipe. The servo motor is equipped with a high-precision encoder, which can accurately feed back the rotor position and realize precise position control and speed control, which facilitates the control of pipe feeding and delivery. After the support assembly 6 operates, the drilling assembly 8 is started, and the electric push rod 81 is started to move the support frame 82 down. The support frame 82 drives the drill 83 to drill holes in the surface of the pipe. In conjunction with the support assembly 6, holes are drilled in different positions of the pipe, making drilling more convenient and eliminating the need for multiple replacements.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
