Abstract
Description
Technical Field
[0001] This utility model is a pipeline engineering testing device, belonging to the field of pipeline engineering. Background Technology
[0002] Pipeline inspection is a crucial step in ensuring the safe operation of pipeline systems, preventing accidents, and guaranteeing the normal operation of important facilities such as water and gas supply. Reasonable inspection and maintenance measures can effectively extend the service life of pipelines and improve their reliability and efficiency. Using robotic equipment equipped with cameras to enter the pipeline and capture videos or photos to inspect the internal structure and scale buildup is a common method in pipeline inspection. Tracked robots are commonly used for inspecting the internal condition of pipelines. However, because the inner wall of the pipeline is curved while the surface of the robot's tracks is flat, the edges of the tracks contact the inner wall of the pipeline, while the middle of the tracks does not. This results in a small contact area between the tracks and the inner wall of the pipeline, leading to low track utilization. Therefore, it is necessary to design a pipeline inspection device that increases the contact area between the tracks and the inner wall of the pipeline. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pipeline engineering inspection device to solve the problems mentioned in the background technology. This utility model increases the contact range between the track and the inner wall of the pipeline.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a pipeline engineering inspection device, comprising a hollow pipe, a camera installed at one end of the hollow pipe, three support plates arranged parallel to the hollow pipe on the outer side of the hollow pipe, the support plates being connected to the hollow pipe via connectors, a drive wheel and a reversing wheel being rotatably mounted at both ends of the support plates, a motor being installed at the end of the support plate near the drive wheel, the output shaft of the motor being connected to the drive wheel, the drive wheel being connected to the reversing wheel via a circular track, multiple slats being equidistantly mounted on the outer surface of the track, the length of the slats being greater than the width of the track, a rubber block being provided on the side of the slats facing away from the track, the side of the rubber block facing away from the slats being machined with an arc-shaped surface that mates with the inner wall of the pipe, two threaded heads being installed on the side of the rubber block facing the slats, and through holes being opened at both ends of the slats to mate with the threaded heads, a nut being threadedly connected to one end of the threaded head through the through hole.
[0005] Furthermore, two L-shaped plates are symmetrically installed on the side of the strip away from the rubber block. The side of the L-shaped plate facing the through hole has a round hole that is aligned with the through hole. The threaded head passes through the channel formed by the through hole and the round hole. The nut is located on the side of the round hole away from the through hole.
[0006] Furthermore, a protrusion is fixedly connected to the middle of the side of the rubber block facing the slat. The protrusion and the rubber block are integrally formed. A slot is provided on the side of the slat facing the rubber block to cooperate with the protrusion. The protrusion is inserted into the slot.
[0007] Furthermore, the protrusion has a rectangular cross-section, and the slot has a rectangular cross-section.
[0008] Furthermore, the rubber block has two symmetrically arranged blind holes on the side facing the strip, and one end of the threaded head is glued into the blind hole.
[0009] Furthermore, the connector includes a first sleeve, on the end of the hollow tube away from the camera, a first sleeve connected to the hollow tube is fitted, and three first connecting plates are installed in a ring at equal intervals on the outer surface of the first sleeve. The end of the first connecting plate away from the first sleeve is connected to a support plate. A third sleeve is fitted on the end of the hollow tube near the camera, and three second connecting plates are installed in a ring at equal intervals on the outer surface of the third sleeve. The end of the second connecting plate away from the third sleeve is connected to the support plate. A reinforcing plate is installed in the middle of the second connecting plate, and a second sleeve is installed on the end of the reinforcing plate away from the second connecting plate. The second sleeve is fitted onto the hollow tube and connected to the hollow tube.
[0010] Furthermore, the support plate has an L-shaped cross-section, and right-angle irons are installed at both ends of the support plate. Two right-angle irons on one support plate are rotatably connected to the drive wheel and the reversing wheel, respectively.
[0011] The beneficial effects of this utility model are:
[0012] 1. Multiple slats are evenly installed on the track surface. Then, rubber blocks with curved surfaces are installed on the slats using a nut and threaded head. After the robot, consisting of a hollow tube, camera, and track, enters the pipe, the curved surface of the rubber block fits against the inner wall of the pipe, thereby increasing the contact area between the track and the inner wall of the pipe. At the same time, under the action of the rubber block, the track does not directly contact the inner wall of the pipe. When a rubber block is worn, the corresponding nut can be removed to replace the rubber block individually.
[0013] 2. When installing the rubber block, make sure one end of the threaded head passes through the through hole and the round hole in sequence, and then tighten the nut to complete the assembly of the rubber block and the strip. At this time, under the support of the L-shaped plate, there is a gap between the nut and the strip. When the nut and the threaded head cannot be properly separated due to rust, which affects the replacement of the rubber block, the threaded head can be cut off by using the gap between the L-shaped plate and the strip.

Detailed Implementation
[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] Please see Figure 1 and Figure 2This utility model provides a technical solution: a pipeline engineering inspection device, including a hollow tube 1, a camera 6 installed at one end of the hollow tube 1, three support plates 10 arranged parallel to the hollow tube 1 on the outside of the hollow tube 1, the support plates 10 having an L-shaped cross-section, a first sleeve 2 connected to the hollow tube 1 fitted onto the end of the hollow tube 1 away from the camera 6, three first connecting plates 3 are installed in an annular shape at equal intervals on the outer surface of the first sleeve 2, the end of the first connecting plates 3 away from the first sleeve 2 being connected to the support plates 10, the hollow tube 1 being close to the camera One end of the head 6 is fitted with a third sleeve 5 that is connected to the hollow tube 1. Three second connecting plates 7 are installed in a ring at equal intervals on the outer surface of the third sleeve 5. The end of the second connecting plate 7 away from the third sleeve 5 is connected to the support plate 10. A reinforcing plate 11 is installed in the middle of the second connecting plate 7. A second sleeve 4 is installed at the end of the reinforcing plate 11 away from the second connecting plate 7. The second sleeve 4 is fitted on the hollow tube 1 and connected to the hollow tube 1. The first connecting plate 3, the second connecting plate 7 and the reinforcing plate 11 together realize the function of connecting the hollow tube 1 and the support plate 10.
[0024] See Figure 1 and Figure 2 Both ends of the support plate 10 are equipped with right-angle irons. The two right-angle irons on one support plate 10 are rotatably connected to the drive wheel 9 and the reversing wheel 12, respectively. A motor 8 is installed at the end of the support plate 10 near the drive wheel 9. The output shaft of the motor 8 is connected to the drive wheel 9. The drive wheel 9 is connected to the reversing wheel 12 through the circular track 14. When the motor 8 is working, it drives the drive wheel 9 to rotate. The drive wheel 9 drives the reversing wheel 12 to rotate through the track 14. Thus, the rotating track 14 cooperates with the inner wall of the pipe, so that the robot formed by the hollow tube 1, camera 6 and other components moves in the pipe, providing images for detecting the internal space of the pipe.
[0025] See Figures 1-6Multiple slats 15 are evenly spaced on the outer surface of the track 14. The length of each slat 15 is greater than the width of the track 14. A rubber block 16 is provided on the side of each slat 15 facing away from the track 14. The side of each rubber block 16 facing away from the slat 15 has an arc-shaped surface that mates with the inner wall of a pipe. Two threaded heads 19 are installed on the side of each rubber block 16 facing the slat 15. Two symmetrically arranged blind holes 23 are formed on the side of each rubber block 16 facing the slat 15, allowing one end of each threaded head 19 to be glued into the blind hole 23, improving the stability of the connection between the threaded head 19 and the rubber block 16. Through holes 21 are formed at both ends of each slat 15 to mate with the threaded heads 19. One end of the head 19 passes through the through hole 21 and is threaded with a nut 18. Multiple slats 15 are evenly installed on the surface of the track 14. Then, by using the nut 18 and the threaded head 19 to cooperate, rubber blocks 16 with arc-shaped surfaces are installed on the slats 15. After the robot formed by the hollow tube 1, camera 6 and track 14 enters the pipe, the arc-shaped surface on the rubber block 16 fits against the inner wall of the pipe, thereby increasing the contact range between the track 14 and the inner wall of the pipe. At the same time, under the action of the rubber block 16, the track 14 does not directly contact the inner wall of the pipe. When a rubber block 16 is worn, the corresponding nut 18 can be removed to replace the rubber block 16 individually.
[0026] See Figures 3-5 Two L-shaped plates 17 are symmetrically installed on the side of the slat 15 away from the rubber block 16. The side of the L-shaped plate 17 facing the through hole 21 has a round hole 22 that is aligned with the through hole 21. The threaded head 19 passes through the channel formed by the through hole 21 and the round hole 22. The nut 18 is set on the side of the round hole 22 away from the through hole 21. When installing the rubber block 16, one end of the threaded head 19 passes through the through hole 21 and the round hole 22 in sequence and then the nut 18 is screwed on to complete the assembly of the rubber block 16 and the slat 15. At this time, under the support of the L-shaped plate 17, there is a gap between the nut 18 and the slat 15. When the nut 18 and the threaded head 19 cannot be properly separated due to rust, which affects the replacement of the rubber block 16, the threaded head 19 can be cut off by using the gap between the L-shaped plate 17 and the slat 15.
[0027] See Figure 5 and Figure 6 A rectangular protrusion 13 is fixedly connected to the middle of the side of the rubber block 16 facing the strip 15. The protrusion 13 and the rubber block 16 are integrally formed. A rectangular slot 20 is provided on the side of the strip 15 facing the rubber block 16 to cooperate with the protrusion 13, so that the protrusion 13 is inserted into the slot 20, thereby improving the stability of the connection between the rubber block 16 and the strip 15.
