A pipeline endoscope probe into the tube auxiliary tooling

Abstract

A pipeline endoscope probe tube auxiliary tool comprises a range retaining rod and a plurality of cross-shaped clamping frames fixed to the range retaining rod. The four ends of the cross of each cross-shaped clamping frame are provided with fixed pulleys respectively. The center of each cross-shaped clamping frame is equipped with a probe tube hole. The circumference of the each cross-shaped clamping frame is provided with a pin hole. The diameter of the probe tube hole matches the outer diameter of the probe tube. The diameter of the pin hole matches the outer diameter of the range retaining rod. The pipeline endoscope probe tube auxiliary tool solves the defects of a conventional endoscope probe tube, greatly improves the inspection effect of the endoscope, and is suitable all portable endoscopic devices currently in use without re-customized purchase, protects and prolongs the service life of the probe tube, and greatly facilitate the operation in pipeline inspection in addition to fast and convenient installation.

Description

technical field [0001] The present invention proposes an auxiliary tooling for an industrial pipeline endoscope (referred to as "endoscope") to penetrate into the pipe, which meets the inspection length and distance requirements of the pipeline endoscope with a diameter above DN100, and improves the inspection effect of the endoscope. , to ensure the internal cleanliness of the pipeline. Background technique [0002] Before the ship pipeline system is closed, it is necessary to use an endoscope to check the internal cleanliness of the pipeline to prevent foreign matter from affecting the normal use of the system; Inspections are carried out visually or by pipeline robots; the inspection stage focuses on the pre-assembled sections that have just been sandwashed to verify that no iron sand has entered the interior of the pipe. [0003] The endoscopes used for DN100-300 pipeline inspection are generally 10-meter-long penetrating tube portable endoscopes, which are purchased fr...

AI Technical Summary

Problems solved by technology

[0006] 1. When inspecting a large-diameter straight pipeline, as the length of the pipeline increases, the internal friction between the pipeline and the pipeline increases, and the rigidity of the pipeline gradually decreases, resulting in coiling in the pipeline;

[0007] 2. In the elbow part of the double 90°parallel bend pipe, the friction force is too large when the penetration pipe passes through the elbow, which may easily cause the penetration pipe to get stuck;

[0008] 3. The rigidity and flexibility of the endoscope insertion tubes of different manufacturers are different, and the working conditions of the pipeline are changeable. In addition, there is no clear applicable standard and experience definition at present, and the endoscope manufacturer cannot effectively grasp the length of production according to the customer. , thus affecting the use effect;

[0009] 4. At present, there is no suitable tooling for endoscope penetration tube to solve the above problems. Only the camera at the front end of the endoscope penetration tube is equipped with a clamp type pulley
