Embodiment Construction

[0019] Such as figure 1 and figure 2 It is a structural principle diagram of a free-spraying robot outside the pipe adopted in the present invention. The walking part of the robot shown in the figure adopts a wheel structure and double motor drive; the circumferential motion system 6 in the figure is a reciprocating swing mechanism composed of an incomplete chain transmission system; four spray guns 8 are evenly arranged and fixed along the circumference On No. 3 sprocket 5; the robot body adopts a split structure, and the upper and lower parts (respectively called the upper body and the lower body of the pipeline robot) realize the rapid installation and disassembly of the robot through the quick operation handle 4. The quick operation handle adopts Eccentric clamping mechanism for fast clamping. Four spray guns are respectively fixed on the spray gun fixing frames of two semicircular rings, and two spray guns are installed on each semicircular fixing frame. One of the ci...

Abstract

The invention relates to a spray finishing machine for pipe outer walls, which can meet the requirement of corrosion protection spray finishing of the outer walls of various straight pipes. A mechanical body consists of a spray finishing mechanism which can swing back and forth, a straight line running mechanism and a body frame, wherein, the spray finishing mechanism which can swing back and forth is composed of an incomplete chain transmission system and can lead a spraygun to swing back and forth around the outer wall of the pipe; the running mechanism is in a wheel type or a caterpillar type and can lead a robot to do continuous or interval straight line running along the pipe; the body frame consists of a lower part and an upper part, and can realize the quick assembly and disassembly of the robot through a quick dismantling handle. Different working devices can be installed on a general mechanical port of the robot to fulfill different pipe maintenance tasks such as descaling, deashing, measuring and welding, etc. at the exterior of the pipe. The spray finishing machine has simple system structure, high reliability and easy guarantee of working quality; the technique can replace the manual way to realize the automation of the maintenance working way such as corrosion protection spray finishing at the exterior of pipes.

Description

technical field [0001] The invention relates to a spraying machine for the outer wall of a pipeline, in particular to use an incomplete chain transmission system to realize the reciprocating swinging spraying operation of the spray gun around the outer wall of the pipeline, and use a wheel type or crawler type walking mechanism to drive the robot to walk along the pipeline. Different operating devices can be installed on the general mechanical interface of this robot to complete different pipeline maintenance tasks, such as rust removal, dust removal, inspection, welding, etc. outside the pipeline. The robot belongs to the research field of pipeline robots and pipeline anticorrosion equipment. Background technique [0002] Pipeline robot is one of the key application fields of robots. It belongs to the research category of special robots. A mechatronic system for a series of pipeline operations such as pipeline construction, maintenance and inspection in the environment. A...
