Description

Technical Field

[0001] This invention relates to the field of testing device technology, specifically a highway pipeline construction testing device. Background Technology

[0002] Highway pipeline construction is an important part of road construction, encompassing multiple stages such as surveying and setting out, trench excavation, foundation treatment, pipeline installation, backfilling and compaction, and inspection and acceptance. Highway pipeline construction inspection equipment is a key technical equipment for ensuring project quality, safety, and efficiency in modern municipal, road, and industrial pipeline construction. Intelligent sensors are the core technical components of modern highway pipeline construction inspection equipment, achieving digitalization, automation, and intelligence of the construction process through high-precision sensing, real-time data acquisition, intelligent analysis, and remote communication.

[0003] Existing highway pipeline construction inspection equipment typically only measures the width and depth of trenches, making it inconvenient to inspect the flatness of the trench bottom. When there are high protrusions at the bottom of the trench, the pipeline placed inside the trench will also protrude to some extent. When the pipeline protrudes to the ground, it affects the burial effect of the pipeline, requiring manual handling, which increases the workload of workers and affects the efficiency of highway pipeline construction.

[0018] 3. By setting up a brush, in conjunction with the connector and air vent, the surface of the roller can be cleaned, preventing dirt from sticking to the surface of the roller and avoiding increasing the friction between the device and the inner wall of the trench. At the same time, it can also spray the marked powder. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-8 The diagram shows a highway pipeline construction inspection device, including a main body 1. A detection component 2 is mounted on the top of the main body 1 via a robotic arm. Two sets of connectors 19 are located at the rear of the main body 1. The two sets of connectors 19 are connected to the main body 1 via a moving mechanism. A support plate 30 is slidably mounted below the connectors 19. A motor 29 is fixedly mounted below the support plate 30. A reel 27 is fixedly mounted at the output end of the motor 29. A connecting rope 28 is wound around the outer surface of the two sets of reels 27. A spraying mechanism is located above the connectors 19.

[0030] Specifically, the main body 1 of the device is placed inside the trench, and moves within the trench. The detection element 2 can detect the conditions inside the trench. The robotic arm can adjust the position and angle of the detection element 2. The detection element 2 uses a smart sensor, which measures the depth of the trench through optics (laser / vision), supports data output and abnormal alarms. The moving mechanism drives two sets of connecting parts 19 to move away from each other. The connecting parts 19 drive the reel 27 to move synchronously. At the same time, the motor 29 drives the reel 27 to unwind the connecting rope 28, enabling the measurement of the trench width. When the main body 1 moves, the two sets of connecting parts... The distance between the connectors 19 is fixed. When the main body 1 of the device cannot move inside the trench, it indicates that the width of the trench is too small. At this time, the detection component 2 will transmit the received information. It should be noted that when the trench width is too large, it will not have much impact on the construction. When the trench width is too small, it will affect the placement of the pipeline. Therefore, during the detection process, it is only necessary to provide a warning for the part with a small trench width. When there is a slope at the bottom of the trench, the main body 1 of the device will move the connecting rope 28. The connecting rope 28 will deform due to the influence of the protruding part. With the cooperation of the spraying mechanism, the marked powder can be sprayed at this position, which is convenient for manual treatment of the trench.

[0031] The moving mechanism includes two sets of sleeves 6, which are connected by a telescopic component and a connector 19. The end of the sleeve 6 away from the connector 19 is rotatably connected to the main body 1 of the device. A push block 8 is slidably installed inside the main body 1 of the device. The push block 8 is located between the two sets of sleeves 6. Rotating seats 9 are installed at both ends of the push block 8. A rail 10 is fixedly installed on the adjacent side of the two sets of sleeves 6. The rail 10 and the rotating seats 9 are slidably connected. A multi-stage hydraulic cylinder 7 is fixedly installed inside the main body 1 of the device. The output end of the multi-stage hydraulic cylinder 7 is fixedly connected to the push block 8.

[0032] Specifically, when the multi-stage hydraulic cylinder 7 is working, it can push the push block 8 to move. The push block 8 drives the rotating seat 9 to move along the length of the track 10. When the push block 8 moves away from the multi-stage hydraulic cylinder 7, the angle between the two sets of sleeves 6 gradually increases, so that the distance between the two sets of connecting parts 19 can be adjusted by adjusting the angle between the two sets of sleeves 6.

[0033] The telescopic assembly includes a support cylinder 11, and there is at least one set of support cylinders 11. The support cylinder 11 is slidably installed inside the sleeve 6. The end of the support cylinder 11 away from the sleeve 6 is fixedly connected to the connector 19. A limit structure is provided between the support cylinder 11 and the sleeve 6. An air inlet pipe 12 is fixedly installed on the top of the sleeve 6. A fan 13 is fixedly installed on the top of the main body 1 of the device. The air outlet of the fan 13 is connected to the sleeve 6 through the air inlet pipe 12.

[0034] The limiting structure includes a crossbar 16, which is fixedly installed inside the support cylinder 11 on the side near the sleeve 6. A limiting block 14 is slidably sleeved on the outer surface of the crossbar 16, and a first spring 17 is movably sleeved on the outer surface of the crossbar 16. The first spring 17 and the limiting block 14 are fixedly connected. A limiting hole 15 is opened on the side of the sleeve 6 away from the track 10, and the limiting block 14 and the limiting hole 15 are inserted into each other.

[0035] Specifically, the fan 13 delivers air into the sleeve 6 through the air inlet pipe 12. As the air between the sleeve 6 and the support cylinder 11 increases, the air pushes the support cylinder 11 to move away from the sleeve 6. In the initial state, the first spring 17 is compressed. When the limiting block 14 moves to the position of the limiting hole 15, the first spring 17 pushes the limiting block 14 to move on the outer surface of the crossbar 16. At this time, the limiting block 14 is inserted into the interior of the limiting hole 15, and the support cylinder 11 and the sleeve 6 are fixed, so that the adjustable distance between the two sets of connecting parts 19 is longer.

[0036] A support frame 5 is fixedly installed on the side of the connector 19 away from the support cylinder 11. A rotating shaft 3 is rotatably installed inside the support frame 5. A roller 4 is fixedly sleeved on the outer surface of the rotating shaft 3. A cleaning component is provided on the side of the support frame 5 close to the connector 19.

[0037] Specifically, when the connector 19 moves, it drives the rollers 4 to move synchronously. When both sets of rollers 4 are in contact with the inner wall of the trench, the connector 19 stops moving. When the main body 1 of the device moves, the rollers 4 can roll on the inner wall of the trench. The rollers 4 drive the rotating shaft 3 to rotate inside the support frame 5. The cleaning component cleans the surface of the rollers 4.

[0038] The cleaning assembly includes an air outlet pipe 18, and a support cylinder 11 is connected to a connector 19 through the air outlet pipe 18. A pressure valve is detachably installed inside the air outlet pipe 18, and an air outlet 20 is provided at the connection between the connector 19 and the support frame 5.

[0039] The cleaning assembly also includes a brush 21, a slide rod 24 is fixedly installed inside the support frame 5, a mounting block 23 is slidably sleeved on the outer surface of the slide rod 24, the mounting block 23 and the brush 21 are fixedly connected, a second spring 26 is slidably sleeved on the outer surface of the slide rod 24, the second spring 26 and the mounting block 23 are fixedly connected, and a lever 25 is fixedly installed on the outer surface of the rotating shaft 3, the lever 25 and the mounting block 23 are in contact and engaged.

[0040] There are two sets of air vents 20. The brush 21 is located between the two sets of air vents 20. Guide plates 22 are fixedly installed on both sides of the brush 21. The guide plates 22 are inclined.

[0041] Specifically, in the initial state, the pressure valve is closed. When the support cylinder 11 stops moving, as the air inside the support cylinder 11 and sleeve 6 increases, the pressure valve opens, and the air enters the interior of the connector 19 through the air outlet pipe 18 and is discharged through the air outlet 20. The air contacts the roller 4 and can blow away the dust attached to the surface of the roller 4. Under the action of the brush 21, the brush 21 contacts the surface of the roller 4. When the roller 4 rotates, the brush 21 can further clean the surface of the roller 4. When the rotating shaft 3 rotates, it drives the lever 25 to rotate. When the lever 25 contacts the mounting block 23, it can drive the mounting block 23 to move on the surface of the slide bar 24. At this time, the second spring 26 is deformed by force, and the mounting block 23 drives the brush 21 and the guide plate 22 to move synchronously. The guide plate 22 can adjust the angle of the air blown out of the air outlet 20.

[0042] The spraying mechanism includes a storage box 31, which is fixedly installed above the connector 19. A discharge pipe 32 is fixedly installed between the storage box 31 and the connector 19. A baffle 33 is provided below the discharge pipe 32. The area of ​​the baffle 33 is larger than the cross-sectional area of ​​the discharge pipe 32. The baffle 33 and the connector 19 are slidably connected. An adjustment structure is provided below the baffle 33.

[0043] The adjustment structure includes a push plate 34, which is fixedly installed below the baffle 33. The push plate 34 slides through the bottom of the connector 19. A rod 35 is fixedly installed below the connector 19. The rod 35 and the support plate 30 are slidably connected. A third spring 36 is movably sleeved on the outer surface of the rod 35. The third spring 36 and the support plate 30 are fixedly connected. The end face of the push plate 34 near the third spring 36 is inclined. The push plate 34 and the support plate 30 are in contact and engaged.

[0044] Specifically, the marked powder is placed inside the storage box 31. In the initial state, the baffle 33 blocks the feed pipe 32, preventing the powder inside the storage box 31 from entering the connector 19. When the connecting rope 28 is under tension, the connecting rope 28 drives the support plate 30 to slide on the outer surface of the rod 35 through the spool 27. At this time, the third spring 36 is deformed by the force, and the support plate 30 moves away from below the push plate 34. Under the action of gravity, the baffle 33 drives the push plate 34 to move downward, allowing the pigment inside the storage box 31 to enter the connector 19. When the air passes through the connector 19, it can spray the pigment inside the connector 19 onto the inner wall of the groove, thereby marking the protruding part at the bottom of the groove. When the main body 1 of the device moves, the connecting rope 28 can pass through the inside of the protruding part, so the device can mark multiple protrusions inside the groove.

[0045] Working principle: The main body 1 of the device is placed inside the trench. The main body 1 moves inside the trench. The detection element 2 can detect the condition inside the trench. The fan 13 delivers air into the sleeve 6 through the air inlet pipe 12. As the air between the sleeve 6 and the support cylinder 11 increases, the air pushes the support cylinder 11 to move away from the sleeve 6. In the initial state, the first spring 17 is compressed. When the limiting block 14 moves to the position of the limiting hole 15, the first spring 17 pushes the limiting block 14 to move on the outer surface of the crossbar 16. At this time, the limiting block 14 is inserted into the inside of the limiting hole 15, and the support cylinder 11 and the sleeve 6 are fixed.

[0046] When the multi-stage hydraulic cylinder 7 is working, it can push the push block 8 to move. The push block 8 drives the rotating seat 9 to move along the length of the track 10. When the push block 8 moves away from the multi-stage hydraulic cylinder 7, the angle between the two sets of sleeves 6 gradually increases. When the connecting piece 19 moves, it drives the roller 4 to move synchronously. When both sets of rollers 4 are in contact with the inner wall of the groove, the connecting piece 19 stops moving. When the main body 1 of the device moves, the roller 4 can roll on the inner wall of the groove. The roller 4 drives the rotating shaft 3 to rotate inside the support frame 5.

[0047] Initially, the pressure valve is closed. When the support cylinder 11 stops moving, as the air inside the support cylinder 11 and sleeve 6 increases, the pressure valve opens, and air enters the interior of the connector 19 through the air outlet 18 and is discharged through the air outlet 20. The air contacts the roller 4 and blows away the dust adhering to the surface of the roller 4. Under the action of the brush 21, the brush 21 contacts the surface of the roller 4. When the roller 4 rotates, the brush 21 can further clean the surface of the roller 4. When the rotating shaft 3 rotates, it drives the lever 25 to rotate. When the lever 25 contacts the mounting block 23, it can drive the mounting block 23 to move on the surface of the slide bar 24. At this time, the second spring 26 is deformed by force, and the mounting block 23 drives the brush 21 and the guide plate 22 to move synchronously. The guide plate 22 can adjust the angle of the air blown out of the air outlet 20.

[0048] The marked powder is placed inside the storage box 31. In the initial state, the baffle 33 blocks the feed pipe 32, preventing the powder inside the storage box 31 from entering the connector 19. When the connecting rope 28 is under tension, the connecting rope 28 drives the support plate 30 to slide on the outer surface of the rod 35 through the spool 27. At this time, the third spring 36 is deformed by the force, and the support plate 30 moves away from below the push plate 34. Under the action of gravity, the baffle 33 drives the push plate 34 to move downward, allowing the pigment inside the storage box 31 to enter the connector 19. When the air passes through the connector 19, it can spray the pigment inside the connector 19 onto the inner wall of the groove, thereby marking the protruding part at the bottom of the groove. When the main body 1 of the device moves, the connecting rope 28 can pass through the inside of the protruding part, so the device can mark multiple protrusions inside the groove.
