Pipe-threading robot for pipeline

Abstract

The invention belongs to the field of robots, and specifically relates to a pipe-threading robot for a pipeline. The pipe-threading robot for the pipeline comprises a main body and three feet connected with the main body, wherein the three feet are of the same structure and arranged uniformly, and every two of the three feet form an included angle of 120 degrees. The main body is composed of a fixing block, a sliding block, a lead screw and a driving device. The interior of the fixing block is fixedly connected with a bare shaft part of the lead screw. The interior of the sliding block is fixedly connected with a thread part of the lead screw. The driving device installed at one end of the fixing block drives the lead screw to rotate. Each foot comprises a parallelogram four-bar mechanism, a guiding and supporting bar, rolling wheels and a driving device. One bar piece of each parallelogram four-bar mechanism is fixedly connected with the fixing block. Bars adjacent to each bar piece are connected with one end of each guiding and supporting bar. The other end of each guiding and supporting bar is connected with the sliding block. The sliding block drives each guiding and supporting bar to rotate in a sliding mode, and then the corresponding parallelogram four-bar mechanism is driven to rotate. Rolling wheels installed on each parallelogram four-bar mechanism are driven by the corresponding independent driving device. A damping device is installed on each guiding and supporting bar.

Description

technical field [0001] The invention belongs to the field of robots, and in particular relates to a pipeline threading robot. Background technique [0002] In the 1970s, due to the rapid development of long-distance and large-diameter pipelines, the communication industry entered the era of pipeline communication. The vigorous development of pipeline communication makes urban underground communication pipelines intersect each other, forming a dense pipeline network. How to complete pipeline threading quickly and efficiently has become a difficult problem in the communication industry. [0003] At present, the wiring of large pipelines is mainly done manually, which is not only labor-intensive but also dangerous; the wiring of small pipelines is mainly done through threading, which is often stuck, time-consuming and laborious. In order to solve the above pipeline threading problems, this project has developed a simple pipeline threading robot device. Through the developmen...
