Description

Technical Field

[0001] The utility model relates to the technical field of pipeline maintenance, in particular to an adjustable natural gas pipeline maintenance device. Background Art

[0002] A natural gas pipeline is a system of pipes used to transport natural gas. These pipes are usually made of steel or plastic pipes and are used to transport natural gas from where it is produced to where it is consumed, such as factories, homes, or commercial buildings. Natural gas pipelines usually pass underground or underwater to ensure safe and efficient transportation of natural gas.

[0003] The long-term use of natural gas pipelines will cause the accumulation of hydrates, sulfides, grease and other devices on the inner wall, and the outer wall of the pipeline will also cause dust accumulation and rust corrosion due to long-term exposure. Therefore, it is necessary to use a natural gas pipeline maintenance device to maintain the pipeline. For example, the prior art Chinese patent announcement number "CN114484082A" discloses an automatic maintenance device for natural gas transmission pipelines, including a device body, a transmission belt and a right arc pipe. The transmission belts are movably connected to the two sides of the inner body of the device, the right side of the device body is movably connected to the right arc pipe, and the left middle part of the device body is fixedly connected to an embedded The driving belt is fixedly connected to the inside with a driving groove, and the driving groove is embedded with a driving tooth. The front periphery of the driving tooth is fixedly connected with a movable column, and the right side of the movable column is movably connected with a second gear. Two second gears are arranged inside the driving belt, which can effectively prevent the middle part of the driving belt from sagging, thereby realizing automatic maintenance of the pipeline, which is more convenient, and also separates the bottom assembly plate from the top assembly plate, thereby dividing the pipeline into two semicircular pipes, which is more convenient for maintenance personnel to repair the internal cleaning mechanism. A stable seat is fixedly provided at the bottom of the support plate to firmly support the pipeline and prevent the pipeline from contacting the ground.

[0004] Some hot weather pipeline maintenance devices can clean the inner wall of the pipeline through a cleaning piece, but in actual operation, on the one hand, similar pipeline maintenance devices cannot adjust the cleaning piece, resulting in the cleaning piece being unable to adapt to the inner wall of pipelines of different diameters; on the other hand, the outer wall of the pipeline also needs maintenance due to long-term wind and sun exposure, and similar pipeline maintenance devices cannot maintain the outer wall of the pipeline, resulting in reduced practicality of the device.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-5An adjustable natural gas pipeline maintenance device includes a base 1, a lifting piece 2 for lifting the pipeline is fixedly installed on the top of the base 1, and a water tank 3 for soaking the pipeline is fixedly installed on the bottom. The bottom surface of the top of the base 1 is slidably connected to a mounting frame 5 through a slide rail 4. A maintenance component 6 is arranged in the mounting frame 5. The maintenance component 6 also includes a cleaning brush 7. The maintenance component 6 and the cleaning brush 7 are detachably connected through a fixing piece 8.

[0022] It is worth mentioning that a cleaning liquid is put into the water tank 3, and then the pipe is placed in the water tank 3 for soaking by using the lifting member 2. After lifting, the maintenance component 6 and the slide rail 4 are used to maintain the pipe.

[0023] Then, a cylinder is provided on the periphery of the slide rail 4, and the axial end of the cylinder is located inside the slide rail 4 and fixedly connected to the mounting bracket 5, and the mounting bracket 5 is driven to move by the action of the cylinder.

[0024] Furthermore, the lifting member 2 includes a pair of cylinders 21 fixedly mounted on the top of the base 1 , and the axial ends of the cylinders 21 are located above the water tank 3 and are fixedly mounted with electric clamps 22 for clamping pipes.

[0025] Furthermore, the maintenance component 6 includes a motor 61 fixedly installed in the mounting frame 5, the axial end of the motor 61 passes through the mounting frame 5 and is fixedly connected to an extension rod 62, one end of the extension rod 62 is slidably connected to a movable seat 65 and is provided with a threaded line 64, and a nut 63 is threadedly connected through the threaded line 64, and the end of the extension rod 62 is sleeved with a first spring 621, and the two ends of the first spring 621 respectively conflict with the side surfaces of the movable seat 65 and the nut 63.

[0026] It is worth mentioning that the motor 61 can drive the plurality of support plates 67 to rotate, so as to clean and maintain the inside of the pipeline.

[0027] Among them, the advantage of providing the first spring 621 and the nut 63 is that the tightness of the first spring 621 can be adjusted by adjusting the position of the nut 63. When the first spring 621 is in a compressed state, the first support rod 651 and the second support rod 661 are squeezed to raise the support plate 67, thereby achieving the effect of adjusting the support plate 67 to adapt to pipes of different diameters.

[0028] In more detail, a pair of fixed seats 66 are fixedly installed at the other end of the extension rod 62, a plurality of first support rods 651 are rotatably connected to the periphery of the movable seat 65, a plurality of second support rods 661 are rotatably connected to the periphery of the pair of fixed seats 66, the other ends of the first support rods 651 and the second support rods 661 are rotatably connected to a support plate 67, the first support rods 651 and the second support rods 661 on the adjacent two sides are arranged opposite to each other, the outer wall of the support plate 67 is provided with the cleaning brush 7, and the cleaning brush 7 can press against the inner wall of the pipe.

[0029] In general, the fixing member 8 includes an I-shaped frame 81 for fixing the cleaning brush 7, and a sleeve 82 is fixedly installed on the other side of the I-shaped frame 81. A slide groove 83 runs through the bottom of the sleeve 82. The interior of the sleeve 82 is slidably connected to a T-shaped rod 84 through the slide groove 83. A second spring 85 is sleeved on the outer periphery of the axial end of the T-shaped rod 84, and the two ends of the second spring 85 are respectively fixedly connected to the side surface of the T-shaped rod 84 and the inner side surface of the sleeve 82.

[0030] It should be noted that the T-bar 84 can be firmly inserted into the slot 88 under the support of the second spring 85 to fix the I-frame 81 , thereby facilitating the replacement of the cleaning brush 7 .

[0031] Finally, the support plate 67 has a T-shaped structure, with a T-shaped slot 86 passing through one side of the support plate 67 and a guide slot 87 communicating with the T-shaped slot 86 passing through the other side thereof. A slot 88 vertically arranged with the guide slot 87 is also provided on the other side of the support plate 67. The I-beam 81 is slidably connected in the T-shaped slot 86, the sleeve 82 is slidably connected in the guide slot 87, and the T-bar 84 can be snapped into the slot 88.

[0032] It is worth mentioning that the advantage of the T-shaped structure of the support plate 67 is that it is convenient to connect a pair of support rods, and the support plate 67 uses the T-slot 86 to facilitate the insertion of the I-frame 81, and the sleeve 82 slides along the guide groove 87 to achieve the purpose of enabling the T-rod 84 to be inserted into the slot 88.

[0033] Working mode: When working, the electric clamp 22 clamps the pipe under the drive of the cylinder 21 to soak the pipe, and then the mounting frame 5 cooperates with the slide rail 4 to clean and maintain the inner wall of the pipe;

[0034] Then, the nut 63 is adjusted according to the diameter of the inner wall of the pipe, so that the nut 63 can adjust the tightness of the first spring 621. The first spring 621 uses its own elasticity to push the movable seat 65 to move. The first support rod 651 cooperates with the second support rod 661 under the push of the movable seat 65 to raise the support plate 67. At this time, the cleaning brush 7 can fit the inner wall of the pipe.

[0035] Finally, pull the T-bar 84 to disengage it from the slot 88, pull out the I-frame 81 to replace the cleaning brush 7, and then insert a new cleaning brush 7 so that the T-bar 84 is snapped into the slot 88 under the support of the second spring 85, thereby achieving the purpose of replacing the cleaning brush 7.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
