Description

Fishing buffer mechanism of pipeline foreign matter fishing robot

Technical Field

The invention relates to a fishing buffer mechanism of a pipeline foreign matter fishing robot, and belongs to the field of pipeline robot protection.

Background

Boiler pipes are difficult to detect and maintain all the time because of small size, poor lighting and thick pipe diameter due to thick wall thickness. External detection has been gradually replaced by endoscopy due to its poor accuracy. Endoscopy is specifically to cut open a conduit communicating with the header, through which the endoscope examines foreign matter in the header. After the endoscope enters the header, the observation range is smaller due to the insufficient intensity of the light source carried by the endoscope. Meanwhile, due to the fact that the size of the power station boiler header is large, after the endoscope enters the header, the signal line is bent, and the specific observation position of the endoscope camera cannot be determined and controlled.

When the endoscope method is not enough to satisfy the needs of detecting a flaw and rejecting, the applicant designs a section can adapt to all kinds of pipelines, and the size is little, can turn round or stretch out and draw back, can drag for various foreign matters, pipeline robot that cleaning performance is strong, but this pipeline robot is owing to be equipped with and advance at the pipeline internal rotation, when meetting the foreign matter and needing to reject, the discharge of foreign matter probably blocks between each structure of robot body to influence the normal operating of robot. In order to adapt to various environments in a pipeline, ensure that the motion of a pipeline robot and foreign matters are not influenced by the foreign matters when being fished, and ensure the service life of the foreign matter fishing robot, the fishing buffer mechanism is very necessary.

In this embodiment, when the second elastic sleeve is an elastic strip or an elastic sheet, a plurality of second elastic sleeves are symmetrically arranged to symmetrically wrap the head of the traveling mechanism. When the second elastic sleeve is an elastic sleeve, the head is integrally wrapped.

Preferably, the fishing buffer mechanism further comprises a gasket, the gasket is arranged between the cotter pin and the pin shaft and fixedly arranged between the cotter pin and the pin shaft, and the fastening structure strengthens the buffer capacity.

Preferably, the number of the fishing buffer mechanisms is at least one, and the fishing buffer mechanisms are distributed at the head of the travelling mechanism at intervals or uniformly.
