Technical Field

[0001] The utility model relates to the technical field of pipeline detectors, in particular to a new type of pressure pipeline crawling detector. Background Technique

[0002] The pipeline crawler is used for defect inspection, repair and other work of various pipelines such as natural gas pipelines, oil pipelines, urban water supply and drainage pipelines, and tap water pipelines, and is an essential equipment for pipeline maintenance.

[0003] After retrieval, the utility model with the patent number CN219639893U and the name of a mobile pressure pipeline leak point positioning detector includes a connecting ring. Through research and analysis, it is found that although it has the advantage of forward detection, to a certain extent, it also has the following disadvantages.

[0004] For example, when encountering a support frame for fixing the pipeline, the forward route is blocked, and it is impossible to climb over the obstacle for continuous detection. It is necessary for the operator to remove it and then install it on the pipeline on the other side of the support frame for detection. The flexibility is poor, and it is restricted by the site environment, resulting in poor versatility and low work efficiency. To solve the above technical problems, we designed a new type of pressure pipeline crawling detector. Content of the Utility Model

The gear ring is fixedly sleeved on the surface of the short rods. One end of the first electric telescopic rod is fixedly penetrated and embedded at the bottom of the frame. The upper end of the first electric telescopic rod is fixedly connected with a toothed plate through bolts. The toothed plate meshes with the first gear. The flipping and adjusting mechanism includes fixing plates, the number of which is two. On the front of the fixing plates, a first motor is fixedly connected through bolts. The rotating shaft of the first motor penetrates through the fixing plate and is fixedly connected with a second motor through bolts. The rotating shaft of the second motor is fixedly connected with the bottom end of the first electric telescopic rod through bolts. On the opposite sides of the two fixing plates, a flipping plate is fixedly connected through bolts. The back of the second motor is rotatably connected with the inner wall of the fixing plate through a rotating shaft. The detection mechanism includes a slider, which is slidably clamped on the surface of the gear ring. On one side of the slider, a third motor is fixedly connected through bolts. The rotating shaft of the third motor penetrates through the slider and is fixedly connected with a second gear through bolts. On the right side of the slider, a fixed block is fixedly connected. On the right side of the fixed block, a square rod is slidably penetrated. On the left end of the square rod, a square block is fixedly connected.

[0008] Preferably, on the front side of the right side of the flipping plate, a controller is installed. On the right side of the flipping plate, a wireless transmitter is installed.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] 1. The utility model clamps the device on the surface of the pipeline, controls the extension of the second electric telescopic rod to move the U-shaped plate and the roller, so that the surface of the roller is in close contact with the surface of the pipeline, controls the operation of the fourth motor and the third motor. The rotation of the rotating shaft of the fourth motor drives the rotation of the roller to crawl on the pipeline surface. The rotation of the third motor makes the second gear rotate. Since it meshes with the toothed ring, the slider reciprocally rotates and moves on the surface of the toothed ring, and then the fixed block, the square rod, the square block and the detector reciprocally rotate and move, so that it has the advantage of being able to detect the pipeline during the crawling process, without the need for manual detection with a handheld detector, improving the detection efficiency, reducing the operation intensity, and being convenient and practical.

[0011] 2. The utility model controls the extension of the first electric telescopic rod at one end to move the toothed plate, makes the first gear rotate, and then separates the two toothed rings at one end, so that the roller disengages from the pipeline surface. Controls the operation of the second motor and the third motor, flips and adjusts the released end to the other side that is not released, and then controls the retraction of the first electric telescopic rod to merge the two toothed rings, so that the roller contacts the surface of the pipeline, and then fixes the other end by flipping in turn, so that it has the advantage of being able to turn over when encountering obstacles, and at the same time can adjust and climb over when the pipeline direction changes, with high flexibility and strong practicability, and is applicable to different conditions.
