Problems solved by technology
After a long period of operation, the pipeline will fail due to reasons such as corrosion, mechanical damage, geological damage, and pipe defects, which will seriously affect the surrounding environment of the pipeline and the lives of the people, and cause a great waste of energy transmission. Therefore, real-time detection is required Quality status of the inner wall of the pipeline
Due to the diversification of pipe shapes and different pipe specifications, many inspection trolleys cannot adapt to their changing requirements
In addition, when there is water or oil in the pipeline, it is difficult for the pipeline trolley to move smoothly in the pipeline
A series of detection barriers make it difficult to detect pipeline quality

Embodiment Construction
[0037] Such as Figure 1 to Figure 23 As shown, the stepping pipeline trolley of the present invention includes an upper layer assembly, a lower layer assembly and a connecting assembly. The upper component is powered by the upper DC motor 6 to make the upper support slider 2 move towards the inner wall of the pipeline, and rely on the pressure between the upper support slider 2 and the inner wall of the pipeline to make the trolley hang in the pipeline. Moreover, the assembly is provided with a mounting hole for the pan / tilt; the lower assembly uses the lower DC motor 24 as a power source, so that the lower support slider 24 is pressed against the inner wall of the pipeline, allowing the trolley to hang in the pipeline; the connecting assembly connects the upper and lower assemblies Closely combined, and use the alternate work of the upper and lower components to promote the longitudinal movement of the trolley.

The invention discloses a stepping type pipeline trolley. The pipeline trolley comprises an upper-layer mounting plate and a lower-layer mounting plate, the front end and the rear end of the upper-layer mounting plate are correspondingly provided with upper-layer supporting guide rails, and upper-layer supporting sliding blocks cooperating with each upper-layer supporting guide rail are arranged at the two ends of the corresponding upper-layer supporting guide rail, and the upper-layer supporting sliding blocks move along the upper-layer supporting guide rails through a first moving device; the front end and the rear end of the lower-layer mounting plate are correspondingly provided with lower-layer supporting guide rails, lower-layer supporting sliding blocks cooperating with each lower-layer supporting guide rail are arranged at the two ends of the corresponding lower-layer supporting guide rail, and the lower-layer supporting sliding blocks move along the lower-layer supporting guide rails through a second moving device; and a connecting assembly used for supporting the upper-layer mounting plate and driving the upper-layer mounting plate to move relative to the lower-layer mounting plate is arranged between the upper-layer mounting plate and the lower-layer mounting plate. The stepping type pipeline trolley can stably advance in pipelines which have various specifications and are in different shapes, and furthermore, can be safely operated in pipelines with certain accumulated water and oil liquid.
Description
technical field [0001] The invention relates to a stepping pipeline trolley, which belongs to the field of detecting the quality of the inner wall of pipelines. Background technique [0002] Pipeline transportation is developed with the increase of oil and natural gas production, and has become the main transportation mode of land oil and gas transportation. develop. After a long period of operation, the pipeline will fail due to reasons such as corrosion, mechanical damage, geological damage, and pipe defects, which will seriously affect the surrounding environment of the pipeline and the lives of the people, and cause a great waste of energy transmission. Therefore, real-time detection is required The quality condition of the inner wall of the pipeline. Due to the diversification of pipe shapes and different pipe specifications, many inspection trolleys cannot adapt to their changing requirements. In addition, when there is water or oil in the pipeline, it is difficult ...
