Combined-type examining walking device inside large-scale pipeline

Abstract

The invention discloses a combined-type examining walking device inside a large-scale pipeline. The device is used for examining the inner surface of the large-scale pipeline with the diameter within the range of 6-12cm. According to the technical scheme, the device is characterized in that a base plate composed of a left rubber wheel, a right rubber wheel and a lower universal wheel is arranged, a lower support, a lower adjusting support, a central speed reduction machine with a central motor, an upper adjusting support, an upper support hydraulic cylinder, a pressure spring and an upper automotive plate are fixed on the base plate, the upper automotive plate is provided with an upper bearing rubber wheel and an upper universal wheel, the upper bearing rubber wheel is synchronously driven by an upper synchronous motor, a central transverse shaft is fixed with a central speed reduction machine shaft, a stretchy arm is fixedly arranged at the end portion of the central transverse shaft, a camera is installed at the front end of the stretchy arm, and the left rubber wheel and the right rubber wheel are driven by a left driving motor and a right driving motor through a left synchronous belt on a left speed reduction machine, a right synchronous belt on a right speed reduction machine, a left driven synchronous wheel on the left speed reduction machine, a right driven synchronous wheel on the right speed reduction machine, a left driving synchronous wheel on the left speed reduction machine and a right driving synchronous wheel on the right speed reduction machine to achieve driving. The technical scheme can be widely applied to the field of examination inside the large-scale pipeline.

Description

Technical field: [0001] The invention is mainly applied to a device for inspecting the inner surface of large pipelines. Background technique: [0002] At present, there is no device for inspecting the inner surface of large-scale pipelines. For large-scale hydropower station water supply pipelines with a diameter of 6-12m, only manual scaffolding can be used for inspection. For some steep pipelines, manual inspection cannot be performed. These giant The pipeline is an extremely important part of the hydropower plant, and it is a position related to the safety of the hydropower plant. Therefore, large-scale hydropower plants urgently need a device that can inspect the cracks, corrosion, voids and other damage on the inner surface of large pipelines, so as to propose maintenance Program. Invention content: [0003] The present invention aims to provide a technical solution for a device capable of walking and working on the inner surface of a large pipeline. The active syn...
