Checking and assessment robot in electric pipeline and assessment method

Abstract

The invention discloses a checking and assessment robot in an electric pipeline and an assessment method. The robot comprises a vertical rod capable of axially traveling forwards, wherein a circular or ring-shaped connecting component is fixed to the front end part of the vertical rod; a ring-shaped supporting sliding component is arranged on the vertical rod in a sleeving mode; outer sides of the connecting component and the supporting sliding component are respectively provided with at least three H-shaped hinged parts which are connected in a radial mode; the H-shaped hinged parts on the connecting component are each hinged with an A wheel supporting rod; the H-shaped hinged parts on the supporting sliding component are each hinged with a short stay rod; the front end parts of the short stay rods are hinged in the middle of the A wheel supporting rods; at least one slide limiting spring for the supporting sliding component is connected between the connecting component and the supporting sliding component; the outer end part of each A wheel supporting rod is provided with a checking A wheel; a B wheel supporting rod with a checking B wheel on the outer end part is further hinged on the A wheel supporting rod between hinged parts at which the checking A wheel and the corresponding short stay rod are hinged on the corresponding A wheel supporting rod; and a supporting B wheel supporting rod spring is connected between hinged parts at which the B wheel supporting rod, the checking A wheel and the B wheel supporting rod are hinged on the corresponding A wheel supporting rod.

Description

technical field [0001] The invention relates to a power pipeline internal inspection and evaluation robot and an evaluation method, which are mainly used for the inspection and evaluation of the power pipeline internal passage, and belong to the technical field of power pipeline safety inspection. Background technique [0002] After the construction of the power pipeline is completed, in order to ensure the safety and convenience of cable laying, it is often necessary to conduct a safety inspection on the power pipeline. Due to the small diameter of the power pipeline and the lack of inspection instruments, the current inspection method It can only be inspected on the outer surface of the power pipeline, that is, the various conditions of the inner wall of the pipe can be known through inspection on the outer wall of the pipeline. This inspection method is obviously not objectively accurate; usually in the construction of power pipelines, Such as sludge blockages, bumps of p...

[0002] After the construction of the power pipeline is completed, in order to ensure the safety and convenience of cable laying, it is often necessary to conduct a safety inspection on the power pipeline. Due to the small diameter of the power pipeline and the lack of inspection instruments, the current inspection method It can only be inspected on the outer surface of the power pipeline, that is, the various conditions of the inner wall of the pipe can be known through inspection on the outer wall of the pipeline. This inspection method is obviously not objectively accurate; usually in the construction of power pipelines, Such as sludge blockages, bumps of pipe welding and damaged parts of pipes, etc. are left in the middle; especially after a period of use, the dislocation of pipe joints caused by the settlement of the ground surface soil will affect the laying of cables and safe use
