Complex pipeline moving rat

Abstract

The invention discloses a complex pipeline moving rat which solves the problem that a moving device in a pipeline can not effectively pass through a complex pipeline and climb a vertical pipeline. The complex pipeline moving rat comprises a retainer and a driving body which are assembled in a pipe wall and is technically characterized in that the retainer and the driving body are assembled on a same main shaft; two motor driving bodies of the driving body are respectively symmetrically hinged between a connecting base of the main shaft and a slide block of the driving body through a link mechanism so that a driving wheel is tensioned in the pipe wall; the motor driving bodies are provided with a DC driving motor and a DC steering motor; and a four-bar mechanism of the retainer, which is provided with a supporting wheel, is hinged between the connecting base of the main shaft and the slide block of the retainer so that the supporting wheel is tensioned in the pipe wall. The invention has reasonable structural design, easy operation, flexible work, stability and reliability, not only can meet the requirement of round pipeline reducing, but also can move in a square pipeline and can climb the vertical pipeline, thereby achieving the aim of moving a self-adaptive pipeline which is compositely driven in complex pipelines, such as a T type pipeline, an L type pipeline or U type pipeline, and the like.

Description

technical field [0001] The invention relates to a moving device in a pipe with an active adjustable drive, in particular to a complex pipe system drilling mouse used for moving inside a pipe with compound motion. It is mainly used as a mobile device for inspection, maintenance and similar operations of various industrial pipelines. Background technique [0002] At present, most of the in-pipe moving devices used in the inspection, maintenance and similar operations of various industrial pipelines in common pipeline systems are driven by screw drive, leg type, crawler type and other structural forms. For example, the patent notification number is CN201074720Y, which introduces a spiral drive mechanism in the "Circular Pipeline Robot Spiral Drive Mechanism". A drive wheel frame is installed on its DC motor shaft. The middle part of the driving wheel bar in the length direction of the body is hinged, the driving wheel bar rear end is equipped with a driving wheel, and the angl...
