Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, specifically a crawling device for pipeline inspection. Background Technology

[0002] A pipeline is a device made up of pipes, pipe fittings, valves, etc., used to transport gases, liquids, or fluids containing solid particles. Due to its unique characteristics, pipelines are widely used in many industries and fields. The uses of pipelines are very wide, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects, and various industrial installations.

[0003] A search revealed a Chinese patent with publication number CN215371556U, which discloses a crawling device for pipeline inspection. During operation, the telescopic support legs extend, causing the rotating wheel to press against the inner wall of the pipeline, thus supporting the carrier within the pipeline. A drive mechanism then rotates the rotating wheel, causing the carrier to move along the length of the pipeline. When an obstacle is encountered during operation, some of the telescopic support legs retract, while the remaining legs continue to support the carrier. The rotating wheel then rotates, allowing the carrier to carry the inspection instrument through the obstacle to continue the inspection operation.

[0004] While the above solutions allow some telescopic support legs to retract when encountering obstacles during operation, while the remaining telescopic support legs continue to support the carrier, enabling the carrier to drive the detection instrument through the obstacle to continue the detection work, the crawling device in the above patent is difficult to disassemble for portability. The non-removable support legs fix the overall size of the device, making it too large to transport easily and increasing transportation costs. Therefore, we provide a crawling device for pipeline inspection to solve the above problems. 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.

[0027] like Figure 1 As shown, this utility model provides a technical solution for a pipeline inspection crawling device, including a connecting column 1. The inner wall of the connecting column 1 has a groove 6. A limiting plate 8 is slidably connected inside the groove 6. One side of the limiting plate 8 is fixedly connected to one end of a second spring 7. The inner wall of the second spring 7 is sleeved with the outer surface of the limiting column 9. A detection device 10 is inserted into one end of the limiting column 9. The outer surface of the detection device 10 is inserted into the inner wall of the connecting column 1. A lighting device 11 is fixedly connected to the outer surface of the detection device 10. The limiting column 9 can fix the detection device 10 to prevent it from falling off during pipeline inspection, thus playing a fixing role. The lighting device 11 is installed around the detection device 10. When the detection device 10 is inspecting, the lighting device 11 can illuminate the inside of the pipeline, which helps to improve the inspection efficiency.

[0028] like Figure 2 and Figure 5 As shown, the outer surface of the limiting post 9 is slidably connected to the inner wall of the connecting post 1. The limiting post 9 penetrates the connecting post 1. The second spring 7 is installed on the limiting post 9, which can support the limiting post 9 and thus improve the fixation of the detection device 10. The limiting post 9 is installed inside the connecting post 1. Pulling the limiting post 9 can release the fixation of the detection device 10, making it convenient to replace the detection device 10. The inner wall of the limiting plate 8 is fixedly connected to the limiting post 9. The limiting plate 8 is installed inside the groove 6 and on the limiting post 9. When the limiting post 9 is pulled, the limiting plate 8 can slide inside the groove 6, which plays a guiding role. The second spring 7 is fixedly connected inside the groove 6. The groove 6 inside the connecting post 1 can be used to install the second spring 7. The groove 6 can control the fixation of the limiting post 9 on the detection device 10, making it convenient to replace the detection device 10 to inspect the inside of the pipeline.

[0029] like Figure 3 and Figure 4As shown, a quick-release mechanism 2 is provided on the outer surface of the connecting column 1. The quick-release mechanism 2 includes a mounting plate 201 fixedly connected to the outer surface of the connecting column 1. A limit rod 206 is snapped into the upper end of the mounting plate 201. A sliding sleeve 205 is fixedly connected to one end of the limit rod 206. The inner wall of the sliding sleeve 205 is slidably connected to the outer surface of the sliding rod 203. The quick-release mechanism 2 is installed on the connecting column 1. When the device needs to be transported, the fixed shell 202 can be removed, which can prevent the support column 5 from occupying a large space during transportation and improve the transportation efficiency.

[0030] One end of the slide rod 203 is fixedly connected to the fixed housing 202. The inner wall of the fixed housing 202 is slidably connected to the outer surface of the limiting rod 206. The limiting rod 206 passes through the fixed housing 202. The other end of the first spring 204 is fixedly connected to the inner side of the fixed housing 202. The limiting rod 206 is installed inside the fixed housing 202. The fixed housing 202 can guide the limiting rod 206 to prevent it from shaking when sliding, thus playing a guiding role.

[0031] A first spring 204 is fixedly connected to the inner side of the fixed shell 202. One end of the first spring 204 is fixedly connected to one side of the sliding sleeve 205. A fixed cylinder 3 is fixedly connected to one side of the fixed shell 202. The inner side of the fixed cylinder 3 is slidably connected to the outer surface of the support column 5. A cable 12 is fixedly connected to one end of the connecting column 1. The support column 5 can slide inside the fixed cylinder 3 and can be adjusted according to pipes of different sizes, which is beneficial to improving the detection effect of the pipe. The cable 12 is installed on the connecting column 1 and can provide power to the connecting column 1, which can make the connecting column 1 crawl inside the pipe. An electric telescopic rod 4 is fixedly connected to the inner side of the fixed cylinder 3. The telescopic end of the electric telescopic rod 4 is fixedly connected to the support column 5.

[0032] The electric telescopic pole 4, the testing equipment 10, and the lighting equipment 11 in this application are all common electrical devices in the prior art, and their models or specific structures will not be described in detail in this application.

[0033] Working principle: When the equipment needs to be transported, the support column 5 on the connecting column 1 needs to be disassembled. By turning the fastening sleeve on the limiting rod 206, the limiting rod 206 can be pressed or pulled. The sliding sleeve 205 slides along the sliding rod 203. Under the action of the first spring 204, the sliding sleeve 205 can be pushed to slide. At this time, the limiting rod 206 is disengaged from the mounting plate 201, and the fixed shell 202 and the connected fixed cylinder 3 and support column 5 can be disassembled from the connecting column 1 as a whole, realizing the rapid separation of the support legs. Each set of support columns 5 is driven by an independently controlled electric telescopic rod 4, which is adjustable. The support dimensions are adjusted so that when entering a variable-diameter pipe, the control system automatically adjusts the extension length of the support column 5 in different positions according to the preset program or real-time sensor data to ensure that the device always maintains a constant contact pressure with the pipe wall. After pulling the limit column 9 outward to compress the second spring 7, the detection device 10 can be taken out. It supports the installation of multi-functional modules such as panoramic cameras, laser rangefinders or gas sensors, which can be quickly replaced. The lighting device 11 provides a light source, which helps to improve the detection efficiency. The cable 12 integrates power supply and communication, and transmits power and communication simultaneously through the waterproof connector cable 12, realizing portable disassembly of the support leg.
