Description

Technical Field

[0001] The present application relates to the field of oil pipelines, and in particular to an oil pipeline detection robot. Background Art

[0002] The inspection robot is a device that inspects the surrounding environment. Due to the harsh working conditions of oil pipelines, some sections of the pipelines are easily corroded, which makes the pipe wall thinner and the strength lower, so that cracks appear and leaks occur. Most of my country's oil pipelines were laid underground in the 1950s and 1960s. After long-term use, the above situation is more likely to occur, so the pipelines must be inspected regularly. If manual excavation is used for inspection, it will not only increase labor costs and low work efficiency, but also damage ground facilities due to excavation, affecting ground traffic conditions.

[0003] The patent document with publication number CN212203602U discloses an oil pipeline inspection robot, which includes a mounting seat, a base and a disc; the present invention can achieve an effective positioning offset effect when the spring and the connecting seat are relatively offset, so that the inspection robot above the mounting seat can effectively realize the movement of the inspection robot under the inner diameter of each oil pipeline when sending a command signal to the motor on the mounting plate to drive the tire to rotate, and the tension of the provided spring can effectively increase the contact force between the four tires and the inner wall of each oil pipeline, so that the inspection robot can more stably implement displacement in each oil pipeline with different inner diameters, thereby effectively satisfying the user's effective inspection operations on various oil pipelines of different diameters, thereby greatly reducing the production cost of mass-produced inspection robots for different diameters and further improving the stability of information capture by the inspection robot.

[0004] The patent document with publication number CN107543010B discloses an oil pipeline inspection robot, which includes an energy supply module, a variable diameter adjustment module and a drive module. The energy supply module includes a battery compartment base, a battery compartment shell, a battery compartment top cover, a front wheel leg, and a front wheel; the variable diameter adjustment module includes a variable diameter adjustment base, a variable diameter adjustment shell, a variable diameter adjustment front top cover, a variable diameter adjustment rear top cover, a support arm, a variable diameter structure sliding member, a middle wheel leg, and a middle wheel; the drive module includes a driving front base, a driving rear base, a driving shell, a driving top cover, a rear wheel leg, a rear wheel, a first gear, a second gear, a third gear, a turbine, a worm, and a drive system; the outer diameter of the oil pipeline inspection robot of the embodiment of the present invention can be adjusted according to the size of the oil pipeline to be inspected, so that the oil pipeline inspection robot of the embodiment of the present invention can be used for the inspection and maintenance of oil pipelines of various different diameters, thereby reducing the inspection and maintenance costs of oil pipelines.

[0030] The implementation principle of an oil pipeline inspection robot in an embodiment of the present application is as follows: when the device needs to be used, first rotate the handle 13, the handle 13 drives the handle 12 to rotate, the handle 12 drives the main rotating rod 9 to rotate, the main rotating rod 9 drives the turntable 15 to rotate, the turntable 15 drives the block 16 to rotate, because the rotation direction of the block 16 does not conflict with the inner slot of the rotating shaft 6, the turntable 15 will not drive the rotating shaft 6 to rotate, and the main rotating rod 9 drives the corresponding first sprocket 10 to rotate, the first sprocket 10 drives the first chain 11 to transmit, the first chain 11 drives the other first sprocket 10 to rotate, so that the transmission shaft 5 on one side of the other first sprocket 10 rotates, and because the inner box 25 is in the outer box 1, and the sixth gear 60 on the inner box 25 presses against the spur gear 22, the spur gear 22 is rotated. The rotating sleeve rod 21 on the side cooperates with the threaded transmission rod 62 and the transmission shaft 5 respectively, so the rotation of the transmission shaft 5 will drive the threaded transmission rod 62 and the fourth rotating rod 23 to rotate, and the threaded transmission rod 62 drives the screw block 3 to rotate, but the screw block 3 cannot rotate due to the restriction of the box 2. Therefore, the screw block 3 drives the fixed block 4 to move along the thread direction of the threaded transmission rod 62, and the fourth rotating rod 23 drives the first stud to rotate, and the first stud drives the first threaded block 61 to rotate, but the first threaded block 61 is restricted by the fixed box 29 and cannot rotate. Therefore, the first threaded block 61 drives the ring box 30 to move, so that the device is adjusted according to the size of the pipeline so that the device can fit the pipeline wall, and then the inner box 25 is lowered. According to the above adjustment, the cleaning roller in the ring box 30 contacts the inner wall of the pipeline, and then it is started The output end of the rotating motor 44 drives the straight rod 49 to rotate, the straight rod 49 drives the corresponding auxiliary tooth sprocket 50 to rotate, the auxiliary tooth sprocket 50 drives the main chain 51 to transmit, the main chain 51 drives another main tooth sprocket 57 to rotate, the main tooth sprocket 57 drives the main transmission rod 56 to rotate, the main transmission rod 56 drives the corresponding auxiliary bevel gear 58 to rotate, the auxiliary bevel gear 58 drives the auxiliary transmission rod 55 on one side of another auxiliary bevel gear 58 to rotate through meshing, the auxiliary transmission rod 55 drives the corresponding third sprocket 59 to rotate, the third sprocket 59 drives another third sprocket 59 to rotate through the third chain 54, the other third sprocket 59 drives the main transmission shaft 52 to rotate, the main transmission shaft 52 drives the fourth gear 53 to rotate, the fourth gear 53 drives the remaining The main transmission shaft 52 rotates, and the main transmission shaft 52 drives the cleaning roller 48 to rotate to clean the pipeline. When the pipeline is inspected again, if there is a blockage in front, the output end of the rotating motor 44 drives the straight rod 49 to rotate, and the straight rod 49 drives the auger shaft 46 to rotate, and the auger shaft 46 drives the drill bit 47 to rotate. The rotating drill bit 47 evacuates the blockage, and then the evacuated blockage is transferred into the device through the groove on the drill bit 47. The auger shaft 46 and the guide plate 45 cooperate to make the blockage pass through the baffle 28 behind the inner box 25 and transport it to the other side of the outside of the inner box 25. After the blockage in the front is removed, the pipeline is inspected by the device. When the inspection is completed and needs to be recycled, the handle 13 is rotated, and the handle 13 drives the handle 12 to rotate, and the above operation is repeated.When the inner box 25 is recovered into the outer box 1, the friction block 17 in the outer box 1 will wipe the surface of the straight line 8 and the inner box 25, and when recovering, the inner box 25 will drive the blockage on the other side to move toward the pipe mouth, thereby unblocking the pipe, and the residue of the blockage on the pipe wall will be cleaned by the cleaning roller 48 and the cleaning roller. When the inner box 25 returns to the outer box 1, the sixth gear 60 on the inner box 25 drives the spur gear 22 to move, so that the rotating sleeve rod 21 and the threaded transmission rod 62 cooperate with the transmission shaft 5, so that the transmission shaft 5 drives the threaded transmission rod 62 and the rotating sleeve rod 21 to rotate, so that the screw block 3 drives the fixed block 4 to return to its position, thereby removing the device and completing the work. ,

[0031] Embodiment 2 The difference between this embodiment and the first embodiment is that a nozzle is fixedly connected to the inside of the outer box 1, and a water inlet pipe is fixedly connected to one side of the nozzle. When it is necessary to clean the inside of the inner box 25, the water inlet pipe and the water pump are connected, and the water pump sends water into the nozzle through the water inlet pipe, and the nozzle sprays water to clean the inside of the inner box 25.

[0032] Embodiment 3 The difference between this embodiment and the first embodiment is that one end of two of the multiple main transmission shafts 52 are fixedly connected to rollers, and the rollers cooperate with the cleaning rollers 48. When the rotating motor 44 drives the main transmission shafts 52 to rotate, the main transmission shafts 52 drive the cleaning rollers 48 and the rollers to rotate, the cleaning rollers 48 clean the pipeline, and the rollers assist the cleaning rollers 48 to move.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
