Abstract

The invention discloses an interpipe self-adaptive crawl mechanism. The interpipe self-adaptive crawl mechanism comprises a frame and a bi-directional lead screw which is connected with the frame in a rotation mode; two screw nuts with opposite spiral directions are connected with the bi-directional lead screw and the two screw nuts are arranged in a bilateral symmetry mode; wheel frames are fixedly connected with the screw nuts, the front and rear of the wheel frames are respectively provided with a crawling belt axle, and two ends of the crawling belt are respectively provided with a crawling belt wheel; a crawling driving belt is arranged on two crawling belt wheels which are arranged at same side of the same wheel frame; a first worm gear is fixedly arranged on the bi-directional lead screw and meshes with a first worm which is connected with a flexible motor shaft; an arbitrary crawling belt axle of the same wheel frame is connected with a second worm gear which meshes with a second worm, the second worm is connected with an output shaft of a crawling motor, and the crawling motor is fixedly arranged on a corresponding wheel frame; and a sliding groove of the screw nuts is formed on the frame and the crawling driving belt is embedded into the groove of the crawling belt wheel. The interpipe self-adaptive crawl mechanism has the advantages of being capable of crawling among parallel pipes and adapting to changed center distance among pipes.

Description

technical field [0001] The invention relates to a crawling mechanism, in particular to an adaptive crawling mechanism between tubes. Background technique [0002] Pipelines are widely used in national production. Due to their large volume and continuous operation, if there is a problem with the pipeline, it will not only affect the normal delivery of products, but also may cause safety hazards and threaten production safety. Therefore, the cleaning and coating of pipelines , welding and testing operations are very important. [0003] For parallel straight long pipes, it is difficult to cover all pipe surfaces in one operation of the pipes to complete the entire pipe operation. In addition, there are various types of pipes, different center distances of pipes, and pipes arranged in parallel are common. And the center distance of the parallel pipes will change in a small range due to manufacturing, installation and other reasons. Therefore, it is necessary for the operating...
