Description
Technical Field
[0001] This utility model relates to the field of pipeline inspection technology, specifically a driving device for pipeline inspection. Background Technology
[0002] Pipeline inspection provides a systematic and intuitive assessment of a range of indicators, including aging, damage, internal blockage, corrosion, and internal structure analysis. The results are primarily based on images, photographs, video recordings, waveform data analysis, and other professional electronic test reports. It is an essential tool for municipal engineering projects, water supply companies, various pipeline inspection agencies, and infrastructure construction companies.
[0003] A patented anti-jamming drive device for pipeline inspection robots, patent CN214467060U, includes a head cover, a housing, a transfer guide shaft, a rubber cup, a rubber sealing disc, a rubber sealing sleeve, a flange baffle, and a hydraulic cylinder. The flange structure at the opening of the housing matches the flange baffle. A sealing partition in the middle of the housing divides the internal space of the housing into a front chamber and a rear chamber, with the front chamber located on the same side as the head cover. The hydraulic cylinder is located in the front chamber and is used to connect the transfer guide shaft and the rubber sealing sleeve. A force transmission washer is connected between the piston rod of the hydraulic cylinder and the rubber sealing sleeve.
[0004] After a long period of time, pipelines need to be inspected and tested regularly. Although the drive device in the aforementioned patent can provide a certain thrust, when encountering bends or when there is dirt on the inner wall of the pipeline, the outer ring of the diaphragm is difficult to fully contact the inner wall of the pipeline, which can easily cause the diaphragm to slip and make it difficult to provide effective thrust to the detection device, thus reducing the stability of the pipeline detection device in driving the detection device to move. To address these issues, we provide a drive device for pipeline detection. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] This utility model provides a technical solution for a drive device for pipeline inspection.
[0023] Please see Figure 1 and Figure 2 The device includes a connecting plate 1, on the surface of which a power mechanism 2 is provided. The power mechanism 2 includes a fixed cover 201 fixedly connected to the connecting plate 1. A transmission gear 203 is rotatably connected to the middle of the fixed cover 201. The transmission gear 203 is interference-fitted to the middle of the fixed cover 201 by bearings. The connecting plate 1 is fixedly installed at the tail end of the pipeline inspection device by bolts, which improves the convenience of installation and disassembly of the drive device. The fixed cover 201 fixes and positions the transmission gear 203, improving the rotational stability of the transmission gear 203.
[0024] The bottom end of the fixed cover 201 is hinged with an inspection door 202. The inside of the fixed cover 201 is rotatably connected to a power gear 204, and the power gear 204 is meshed with the transmission gear 203. The inspection door 202 facilitates the installation and maintenance of the internal devices of the fixed cover 201, reduces the difficulty of linking the controller 206 with the detection device, and improves the convenience of device connection and maintenance. The power gear 204 controls the rotation of the transmission gear 203.
[0025] The first motor 205 is fixedly connected inside the fixed cover 201, and the output end of the first motor 205 is fixedly connected to the power gear 204. The controller 206 is fixedly connected inside the fixed cover 201, and the controller 206 is electrically connected to the first motor 205. When encountering a horizontal bend, the controller 206 controls the first motor 205 to start, controls the power gear 204 to rotate, adjusts the angle value of the fixed shell 306, so that the power wheel 402 abuts against the inner wall of the outermost ring of the bend, and improves the stability of the movement of the detection device driven by the power wheel 402.
[0026] Please refer to it again. Figure 1 and Figure 3 A support mechanism 3 is connected to the middle of the transmission gear 203. The support mechanism 3 includes a support plate 301 fixedly connected to the transmission gear 203. A support rod 302 and a pressure tube 303 are respectively hinged to both ends of the support plate 301. A fixed shell 306 is fixedly connected to the top of the support rod 302. The support plate 301 is rotated by controlling the transmission gear 203, so that the support rod 302 drives the fixed shell 306 to rotate, and the angle of the fixed shell 306 is adjusted.
[0027] The pressure tube 303 is internally slidably connected to a sliding rod 304, and the movement of the sliding rod 304 is rotatably connected to the support rod 302. The edge of the support plate 301 is connected to a reinforcing ring. The sliding rod 304 is fixed by the pressure tube 303, and the support rod 302 is buffered and positioned by the pressure tube 303 and the sliding rod 304.
[0028] The other end of the sliding rod 304 is fixedly connected to a telescopic spring 305, and the telescopic spring 305 is fixedly connected to the pressure pipe 303. When the telescopic spring 305 is in a contracted state, it provides tension to the sliding rod 304, thereby causing the power wheel 402 to come into close contact with the inner wall of the pipe.
[0029] Please refer to it again. Figure 1 and Figure 4 A drive mechanism 4 is provided in the middle of the fixed housing 306. The drive mechanism 4 includes a first sprocket 401 that is rotatably connected to the fixed housing 306. Both ends of the first sprocket 401 are fixedly connected to a power wheel 402. The fixed housing 306 fixes the positions of the first sprocket 401 and the power wheel 402.
[0030] The pressure pipe 303 provides tension to the support rod 302, causing the power wheel 402 to come into close contact with the inner wall of the pipe. The first sprocket 401 controls the rotation of the power wheel 402, and the friction between the power wheel 402 and the inner wall of the pipe generates thrust, driving the pipe inspection device to move forward.
[0031] The fixed housing 306 has a second sprocket 403 rotatably connected inside, and the second sprocket 403 is connected to the first sprocket 401 through a chain. The second sprocket 403 drives the first sprocket 401 to rotate synchronously through the chain, so that the first sprocket 401 controls the rotation of the power wheel 402.
[0032] A second motor 404 is fixedly connected to the surface of the fixed housing 306, and the output end of the second motor 404 is fixedly connected to the second sprocket 403. The second motor 404 is electrically connected to the controller 206. The controller 206 can control the second motor 404 to start and control the second sprocket 403 to rotate.
[0033] The controller 206 is electrically connected to the processor of the pipeline detection device. The first motor 205 and the second motor 404 are electrically connected to the power supply of the pipeline detection device through wires. The controller 206, the first motor 205 and the second motor 404 are existing technologies, and their detailed parameters and models will not be described in detail in this application.
[0034] In use, this utility model is as follows: First, the connecting plate is fixedly installed at the end of the pipeline inspection using bolts. The inspection door is opened, and the drive unit is electrically connected to the inspection equipment. The inspection equipment is pushed into the pipeline, causing the support wheel of the inspection equipment to contact the inner wall of the pipeline. The telescopic spring 305 provides tension to the sliding rod 304, thereby causing the power wheel 402 to contact the inner wall of the pipeline tightly. The first motor 205 controls the rotation of the power gear 204, causing the power wheel 402 to contact the highest point of the pipeline. The second motor 404 controls the rotation of the second sprocket 403. Through chain transmission, the first sprocket 401 controls the rotation of the power wheel 402, and the power wheel 402 contacts the pipeline... The friction of the inner wall generates thrust, driving the pipeline inspection device forward. When the pipeline inspection device detects a bend ahead, the first motor 205 controls the power gear 204 to rotate, causing the transmission gear 203 to drive the support plate 301 to rotate, adjusting the support plate 301 to a horizontal position, so that the power wheel 402 abuts against the inner wall of the outermost ring of the bend, improving the stability of the movement of the inspection device driven by the power wheel 402. Through the above device, it is avoided that the power wheel 402 touches the accumulation at the bottom of the pipeline when the device is driven by the power wheel 402, and the power wheel 402 can provide a stable thrust to the pipeline inspection device when encountering a bend, thus improving the stability of the movement of the pipeline inspection device.
