Removal limiting mechanism of pipeline robot

Abstract

The invention discloses a removal limiting mechanism of a pipeline robot. The removal limiting mechanism comprises a mounting bracket, a waste collection cavity and an adjusting block, the mounting bracket is adjustably fixed at a pipeline opening, the waste collection cavity and the pipeline opening form an impurity discharge channel, and the adjusting block is movably fixed in the waste collection cavity. The removal limiting mechanism of the pipeline robot is simple in structure, low in manufacturing cost, compact in structure, free of special requirements for installation space, free of electrical control, capable of adjusting the passing cross section of materials according to needs, capable of achieving mechanical follow-up, convenient to mount, dismount and maintain and capable of guaranteeing normal removal work of the pipeline robot.

Description

Technical field [0001] The present invention relates to a row of pipeline robots, belonging to the field of pipeline robot protection. Background technique [0002] Boiler pipes have been difficult to detect and maintain due to small size, poor lighting, and thick tube diameters. External detection is gradually replaced by endoscopic methods due to poor accuracy. The endoscopic method is specifically to cut the pipe with the unicom Unicom, and the endoscope is checked. After the endoscope enters the unpack, the range of observations is smaller due to insufficient source of light from the endoscope. At the same time, after the size of the power plant boiler is large, the endoscope enters the link, the signal line will be bent, and the specific observation position of the endoscope camera head cannot be determined. [0003] When the endoscopic method is not sufficient to meet the need for flaw detection and decentralization, the applicant has designed a pipeline robot that can acco...

Problems solved by technology

After the endoscope enters the header, due to the insufficient light source intensity of the endoscope, the observation range is small

At the same time, due to the large size of the boiler header of the power station, after the endoscope enters the header, the signal line will be bent, and it is impossible to determine and control the specific observation position of the endoscope camera

[0003] When the endoscopic method is not enough to meet the needs of flaw detection and rejection, the applicant designed a pipeline robot that can adapt to various pipelines, is small in size, can be bent or stretched, can pick up various foreign objects, and has strong cleaning capabilities. However, since the pipeline robot mainly rotates and advances in the pipeline, the pipeline entrance is generally relatively fixed. However, when there are many foreign objects in the pipeline, the discharge speed is uneven or the discharge angle is large, impurities may be blocked, affecting the normal rejection of the pipeline mouth. Therefore, setting the exclusion limit mechanism on the pipe mouth and the robot body can control the speed and flow of impurities to ensure that the foreign matter is discharged from the pipeline evenly and orderly.
