Large-traction-force screw propulsion micro-pipeline robot based on urban construction

Abstract

The invention discloses a large-traction-force screw propulsion micro-pipeline robot based on urban construction, and particularly relates to the field of urban construction. The large-traction-forcescrew propulsion micro-pipeline robot based on urban construction comprises equipment carrying bins, a cable driving wire, propulsion structure bins, universal joint mechanisms, a detection equipmentbin and a spiral driving bin; and the ends of the equipment carrying bins and the ends of the propulsion structure bins are provided with matched threaded ends respectively to be sleeved with threadedpipe structures, the ends of the equipment carrying bins are in threaded connection with the ends of the propulsion structure bins, and the universal joint mechanisms are located at the ends of the equipment carrying bins, the ends of the propulsion structure bins and the end of the detection equipment bin. According to the scheme, the pipeline robot is of a split type assembling structure, the equipment carrying bins, the propulsion structure bins, the detection equipment bin and the spiral driving bin are connected and assembled in a threaded manner or connected through the universal jointmechanisms, and the proper length and number can be selected according to actual scene requirements; and the traction force of the pipeline robot is changed by increasing or decreasing the number of the propulsion structure bins, so that the pipeline robot is suitable for working in different environments, and operation scenes are expanded.

Description

technical field [0001] The present invention relates to the technical field of city construction, more specifically, the present invention is a kind of helically propelled tiny pipe robot based on large traction force for city construction. Background technique [0002] In today's society, all kinds of tiny pipes (less than 20mm in diameter) have been widely used in urban construction. Pipeline robots have been applied to various fields related to people's lives. Macro pipe robots have conventional processing modes. Compared with the micro-pipeline robot, the design of the macro-pipeline robot is simpler, and it is not suitable for small or micro-pipelines in some aspects of practical application, so a robot that is especially suitable for small pipelines is needed to clean small pipelines. Although some micro-pipeline robots have been industrialized, some problems have not been fundamentally solved. At present, the integration of pipeline, detection, movement and repair of ...

AI Technical Summary

Problems solved by technology

[0004] The existing pipeline cleaning robot has a single structure and shape, and is mainly pulled by installing the driving wheel on the side of the cylindrical machine. When there is a lot of silt in the pipeline, the traction force is small and it is easy to slip or fail to pass through the silt. The friction of movement is not easy to increase, resulting in limited load capacity and poor traction ability of the robot; at the same time, in some complex working conditions such as curved pipes, there are a large number of curved pipes and U-shaped pipes in the working environment of the robot, and due to corrosion, fatigue, etc. There are pipe diameter changes due to damage, cracks, pipe joints, etc., which requires the micro-pipeline robot to have a small radial size, good passability at bends and U-shaped pipes, and strong adaptability to variable pipe diameters. As a result, the equipment stays in the pipeline, the traditional pipeline robot cannot pass through, the scope of application is limited, and there are major defects
