Robot for cleaning inner wall of pipe

Abstract

The invention discloses a robot for cleaning the inner wall of a pipe. A motor and guide shafts are mounted on a lower mounting plate. The lower end of each guide shaft is fixed to the lower mounting plate. A nut is in threaded connection to a screw rod and provided with three or more radially-extending-and contracting assemblies in the circumferential direction. Among the radially-extending-and contracting assemblies, the upper side and the lower side of each large linear motor are each provided with a small linear motor in a symmetrical manner; a piston rod of each large linear motor is fixed to the center of a rubber block, and a piston rod of each small linear motor is fixed to a radially-moving block; the upper side and the lower side of each roll brush are each provided with a sealing and fixing device in a symmetrical manner, and a set of liquid passing holes are uniformly formed in the rim of a fixing disc in each sealing and fixing device in the circumferential direction; the upper end of the screw rod is matched with the fixing disc of the lower sealing and fixing device in a rotary manner, and the upper ends of the guide shafts are fixed to the corresponding fixing disc; and a roll brush motor is mounted on the fixing disc of the upper sealing and fixing device. By means of the robot for cleaning the inner wall of the pipe, contaminants on the inner wall of the pipe can be removed thoroughly and efficiently.

Description

technical field [0001] The invention belongs to the field of pipeline cleaning, in particular to a pipeline inner wall cleaning robot. Background technique [0002] In the material or chemical industry, the cleanliness of the inner wall of the reaction medium conveying pipeline is an important part of determining the purity of the product, so it is often necessary to use cleaning agents for professional cleaning. At present, manual cleaning is the most common cleaning method and is commonly used in daily work. However, for some pipes such as vertical installation, too long length, too large or too small inner diameter, manual cleaning often has low cleanliness, low efficiency, complex pollutants and cleaning agents, and even toxic, flammable, etc., so there are Large security risks, and high labor costs and other defects. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cleaning robot for the inner wall of the...
