Description

Technical Field

[0001] This utility model belongs to the field of pipeline inspection technology, and specifically relates to a climbing device for pipeline inspection. Background Technology

[0002] The interconnected pipeline systems in cities are closely related to the safety of citizens. These mainly include water supply pipeline systems, sewage discharge pipeline systems, and natural gas supply pipeline systems. In particular, since the 1970s, with the rapid development of the petroleum, chemical, natural gas, and nuclear industries, pipelines, as an important material transportation facility, have brought great convenience to people's lives and production, and have therefore been more widely used.

[0003] In pipeline production, it is usually necessary to inspect the inner wall of the pipeline to prevent corrosion, cracks, and other problems that could lead to leaks during subsequent use. Currently, pipeline inner wall climbing devices are used for this inspection. These devices rely on the pressure of wheels on the inner wall of the pipeline to complete the movement and inspection. However, existing devices have poor adaptability and can only inspect pipelines with uniform or small variations in inner diameter. They cannot adapt to the inspection of pipelines with different diameters, which reduces the practicality of the device and affects the efficiency of pipeline inspection.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a climbing device for pipeline inspection to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a climbing device for pipeline inspection, including a main body, an inspection camera installed on one side of the main body, a drive component installed on the main body, a transmission component installed in the inner cavity of the main body, a plurality of adjustment components installed on the transmission component, and a moving component installed on each of the adjustment components.

[0008] The detection camera is used to detect the condition of the inner wall of the pipe, the moving component is used to move on the inner wall of the pipe, the driving component is used to drive the transmission component to rotate, and the rotation of the transmission component can drive the adjustment component to move in position so that the moving component can expand outward to adapt to the inner wall of pipes with different diameters.

[0009] Furthermore, a fixed seat is installed on the inner wall of one end of the main body, and a fixed slide rail is installed on the fixed seat. The fixed slide rail can slide with the transmission component. A number of positioning sliders are evenly installed on the fixed seat. The number of positioning sliders is the same as that of the adjustment component. One adjustment component can slide with one positioning slider.

[0010] Furthermore, the transmission assembly includes a rotating ring, which is slidably installed in the fixed slide rail. A toothed ring is installed on the inner side of the rotating ring. The transmission assembly also includes a plurality of rotating rods, the number of which is the same as that of the adjustment assembly. All rotating rods are installed on the inner wall of the main body, and each rotating rod is rotatably mounted with a rotating gear, which meshes with the toothed ring.

[0011] Furthermore, the drive assembly includes a first motor, which is mounted on one end of the main body. A first drive shaft is mounted on the shaft of the first motor, and a drive gear is mounted on one end of the first drive shaft. The drive gear meshes with the gear ring.

[0012] Furthermore, the adjustment component includes a sliding plate, which is slidably mounted on the positioning slider. A rack is mounted on one side of the sliding plate, which meshes with the rotating gear. One end of the sliding plate extends through the main body to the outside. A fixed plate is mounted on one end of the sliding plate and the outside of the housing. The moving component is mounted on the fixed plate.

[0013] Furthermore, the movable component includes a mounting plate, on one side of which is a sliding rod. There are two sliding rods, which are slidably mounted through the fixed plate. Each sliding rod is surrounded by a spring, one end of which contacts the surface of the mounting plate, and the other end of which contacts the fixed plate. The mounting plate is equipped with two mounting brackets, each with a wheel.

[0014] Furthermore, the moving component also includes a second motor, which is mounted on the mounting plate. A second drive shaft is mounted on the shaft of the second motor, and a connecting disc is mounted on the second drive shaft. A first rotating disc is mounted on one end of one of the walking wheels. The first rotating disc is connected to the connecting disc by a belt. A second rotating disc is mounted on each of the two walking wheels, and the two second rotating discs are connected by a belt.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model uses a drive component to drive a rotating component to rotate, which in turn drives an adjusting component to expand outward. This allows the moving component to be flexibly adjusted according to the inner diameter of the pipe to be inspected, enabling it to adapt to pipes of different diameters for inspection, thus improving practicality and efficiency of pipe inspection.

[0017] 2. This utility model slides a sliding rod through and installs it on a fixed plate. A spring is installed around the sliding rod, with one end of the spring in contact with the mounting plate and the other end in contact with the fixed plate. The elastic release force of the spring makes the contact between the traveling wheel and the inner wall of the pipe more compact, preventing the traveling wheel from slipping and improving the walking operation effect.

Detailed Implementation

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figures 1-7 As shown, this utility model is a climbing device for pipeline inspection, including a main body 1, an inspection camera installed on one side of the main body 1, a drive assembly 3 installed on the main body 1, a transmission assembly 4 installed in the inner cavity of the main body 1, a plurality of adjustment assemblies 5 installed on the transmission assembly 4, and a moving assembly 6 installed on each of the adjustment assemblies 5.

[0032] The detection camera is used to detect the condition of the inner wall of the pipe. The moving component 6 is used to move on the inner wall of the pipe. The driving component 3 is used to drive the transmission component 4 to rotate. The rotation of the transmission component 4 can drive the adjustment component 5 to move in position so that the moving component 6 can expand outward to adapt to the inner wall of pipes with different diameters.

[0033] In practical use, when it is necessary to inspect the inner wall of a pipe, this device can be placed inside the pipe so that the moving component 6 contacts the inner wall. Then, by driving the moving component 6, the device can move inside the pipe. The inspection camera detects the internal condition of the pipe and informs the operator. When it is necessary to inspect pipes of different diameters, the drive component 3 can be activated to drive the transmission component 4 to rotate. The rotation of the transmission component 4 simultaneously drives the moving component 6 to expand outward. With the movement of the adjustment component 5, the moving component 6 is driven to expand outward, so that the radius of the moving component 6 from the axis of the housing can change. This allows it to adapt to pipes of different diameters and move on their inner walls to carry out inspection work.

[0034] This invention enables the drive component 3 to rotate the rotating component, which in turn drives the adjustment component 5 to expand outward. This allows the moving component 6 to be flexibly adjusted according to the inner diameter of the pipe to be inspected, thus adapting to pipes of different diameters for inspection, improving practicality and increasing the efficiency of pipe inspection.

[0035] In one embodiment, for the aforementioned main body 1, a fixed seat 7 is installed on the inner wall of one end of the main body 1, and a fixed slide rail 8 is installed on the fixed seat 7. The fixed slide rail 8 can slide with the transmission component 4. A plurality of positioning sliders 9 are evenly installed on the fixed seat 7. The number of positioning sliders 9 is the same as that of the adjustment component 5, and one adjustment component 5 can slide with one positioning slider 9.

[0036] By installing a fixed slide rail 8 on the fixed base 7, the transmission component 4 can be positioned and guided, allowing the transmission component 4 to slide smoothly within the fixed slide rail 8 under the drive of the drive component 3. The positioning slider 9 installed on the fixed base 7 can be positioned and guided, allowing the adjustment component 5 to slide stably on the positioning slider 9 under the drive of the transmission component 4, while expanding outward to adjust the diameter of the moving component 6 from the axis of the main body 1.

[0037] In one embodiment, the transmission assembly 4 includes a rotating ring 10, which is slidably mounted in the fixed slide rail 8. A toothed ring 11 is mounted on the inner side of the rotating ring 10. The transmission assembly 4 also includes a plurality of rotating rods 12, the number of which is the same as that of the adjustment assembly 5. All rotating rods 12 are mounted on the inner wall of the main body 1, and rotating gears 13 are rotatably mounted on each rotating rod 12. All rotating gears 13 mesh with the toothed ring 11.

[0038] The drive component 3 can drive the gear ring 11 to rotate, so that its rotating ring 10 can rotate and slide on the fixed slide rail 8. The rotation of the gear ring 11 drives the rotating gear 13 on the rotating rod 12 to rotate. The rotating gear 13 drives all the adjusting components 5 to expand outward at the same time, so as to cause the moving component 6 to change in length, which can adapt to pipes of different diameters and improve practicality.

[0039] In one embodiment, the drive assembly 3 includes a first motor 14, which is mounted on one end of the main body 1. A first drive shaft 15 is mounted on the axis of the first motor 14, and a drive gear 16 is mounted on one end of the first drive shaft 15. The drive gear 16 meshes with the gear ring 11.

[0040] By driving the first motor 14, the first drive shaft 15 can be rotated, which in turn drives the drive gear 16 to rotate, and the rotation of the drive gear 16 drives the gear ring 11 to rotate.

[0041] In one embodiment, the adjustment component 5 includes a sliding plate 17, which is slidably mounted on the positioning slider 9. A rack 18 is mounted on one side of the sliding plate 17, and the rack 18 meshes with the rotating gear 13. One end of the sliding plate 17 extends through the main body 1 to the outside. A fixed plate 19 is mounted on one end of the sliding plate 17 and the outside of the housing. The moving component 6 is mounted on the fixed plate 19.

[0042] By rotating the gear 13, the rack 18 can be moved, causing the sliding plate 17 to slide on the positioning slider 9, thereby causing the fixed plate 19 to expand outward from the main body 1. This causes the moving component 6 installed on the fixed plate 19 to change length, thus enabling the device to be flexibly adjusted according to the diameter of the pipe, so as to be able to adapt to the inner wall inspection of pipes of various diameters and improve work efficiency.

[0043] In one embodiment, the moving component 6 includes a mounting plate 20. A sliding rod 21 is mounted on one side of the mounting plate 20. There are two sliding rods 21. The sliding rods 21 are slidably mounted on the fixed plate 19. A spring 22 is mounted around each sliding rod 21. One end of the spring 22 is in contact with the surface of the mounting plate 20, and the other end of the spring 22 is in contact with the fixed plate 19. A mounting bracket 23 is mounted on the mounting plate 20. There are two mounting brackets 23, and each mounting bracket 23 is equipped with a traveling wheel 24.

[0044] By contacting the inner wall of the pipe with the traveling wheel 24, it can rotate on the mounting bracket 23, driving the device to move inside the pipe for inspection. The sliding rod 21 is slidably installed on the fixed plate 19, and a spring 22 is installed around the sliding rod 21. One end of the spring 22 contacts the mounting plate 20, and the other end contacts the fixed plate 19. The elastic release force of the spring 22 can make the contact between the traveling wheel 24 and the inner wall of the pipe more compact, preventing the traveling wheel 24 from slipping and improving the walking operation effect.

[0045] In one embodiment, the moving component 6 further includes a second motor 25, which is mounted on the mounting plate 20. A second drive shaft 26 is mounted on the axis of the second motor 25, and a connecting disc 27 is mounted on the second drive shaft 26. A first rotating disc 28 is mounted on one end of one of the walking wheels 24, and the first rotating disc 28 is connected to the connecting disc 27 by a belt. A second rotating disc 29 is mounted on each of the two walking wheels 24, and the two second rotating discs 29 are connected by a belt.

[0046] The second motor 25 drives the connecting disc 27 on the second drive shaft 26 to rotate. The connecting disc 27 is connected to the first rotating disc 28 by a belt, so that the connecting disc 27 can drive the moving wheel 24 to rotate. The two rotating discs 29 are connected by a belt, so that when the second motor 25 is started, the two wheels 24 will rotate simultaneously, thus enabling the device to move on the inner wall of the pipe and perform inspection work on the inner wall of the pipe.

[0047] In summary, by means of the above-mentioned technical solution of this utility model, the first drive motor 14 drives the first drive shaft 15 to rotate, and the first drive shaft 15 drives the drive gear 16 to rotate, which in turn drives the gear ring 11 to rotate. Under the rotation of the gear ring 11, the rotating ring 10 rotates and slides on the fixed slide rail 8. The rotation of the gear ring 11 drives the rotating gear 13 on the rotating rod 12 to rotate, and the rotating gear 13 drives the rack 18 to move, so that the sliding plate 17 slides on the positioning slider 9, thereby driving the fixed plate 19 to expand outward from the main body 1. This causes the mounting plate 20 installed on the fixed plate 19 to move outward, so that the radius of the traveling wheel 24 from the housing axis can change. Thus, this device can flexibly adjust the traveling wheel 24 according to the pipes of different diameters, adapt to pipes of different diameters, and perform internal inspection operations, thereby improving its practicality.

[0048] Through the above technical solutions, 1. The drive component 3 can drive the rotating component to rotate, and the rotating component can drive the adjusting component 5 to expand outward at the same time, thereby enabling the moving component 6 to flexibly adjust according to the inner diameter of the pipe to be inspected, which can adapt to pipes of different diameters for inspection, improve practicality, and improve the efficiency of pipe inspection; 2. By sliding the sliding rod 21 through and installing it on the fixed plate 19, and installing the spring 22 around the sliding rod 21, with one end of the spring 22 in contact with the mounting plate 20 and the other end in contact with the fixed plate 19, the elastic release force of the spring 22 can make the contact between the traveling wheel 24 and the inner wall of the pipe more compact, avoid the traveling wheel 24 from slipping, and improve the walking operation effect.
