Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of in-pipeline detection, and in particular relates to a chain-type pipeline robot with a diameter-changing function. Background Art
[0002] In today's society, while road, rail, and air transportation have formed a relatively well-developed transportation network, pipeline transportation still holds a pivotal position in the transport of fluids (such as oil, natural gas, and water). Compared to other modes of transportation, pipeline transportation not only offers advantages such as large capacity, high continuity, and high safety, but also effectively reduces environmental pollution and energy consumption, making it a key means of achieving efficient resource allocation and sustainable development.
[0003] However, pipeline transportation systems also face numerous challenges, particularly regarding pipeline health monitoring and maintenance. Because pipelines are often laid underground or exposed to complex environments such as high temperatures and high pressures, internal and external corrosion, wear, and cracks are difficult to observe directly, posing significant risks to their safe operation. A pipeline leak not only wastes resources and pollutes the environment, but can also cause catastrophic accidents such as fires and explosions, posing a serious threat to public life and property.
[0004] Traditionally, pipeline inspection and maintenance operations rely on pipeline robots, which are electromechanically driven devices designed specifically for traveling inside pipelines. They can carry various sensors or maintenance tools to perform pipeline inspection and maintenance tasks. However, under existing technical conditions, pipeline robots of corresponding sizes must be customized to suit pipeline systems of different diameters. This approach not only limits the widespread application of pipeline robots, but also significantly increases the cost of inspection and maintenance, while consuming a large amount of labor and time resources. In addition, since pipelines are mainly used for the transportation of fluid materials, their internal environment is often complex, which makes it difficult for pipeline robots to maintain a stable and safe operating state in such environments, thereby increasing the risk of serious accidents.

[0031] like Figure 2 、 Figure 5 As shown, the drive assembly includes a motor base 201, a telescopic motor 202, a telescopic motor connector 203, a wheel 204 and a drive shaft 205. The lower end of the motor base 201 is fixedly connected to the robot body 1 by screws, and one end of the telescopic motor 202 is fixedly installed on the upper end of the motor base 201.
