Abstract

The invention provides a guiding support, which is a component for an intelligent petroleum pipeline cleaner, with the holding power adjustable. The guiding support comprises a pedestal, a three-pointconnecting rod and an elastic component; the pedestal is connected with the main body of the intelligent petroleum pipeline cleaner; the three-point connecting rod is provided with and passes througha hinge support hole; the three-point connecting rod is connected with the pedestal, a guide wheel and the elastic component; the invention provides a guiding support with easily adjustable characteristic relation between the displacement and elasticity with sound universality.

Description

technical field [0001] The invention provides a bracket, specifically a bracket with adjustable support force, which is a component of an intelligent pig for oil and gas pipelines and a gravity support device for an instrument compartment of the pig. Background technique [0002] The guide bracket is an important part of the smart pig, and it is mainly used to ensure a good dynamic seal between the pig cup and the pipeline, so that the smart pig can walk along the pipeline under the action of the pressure difference between the front and rear of the pig cup , at the same time keep the intelligent pipe pig instrument warehouse always near the pipeline axis when moving in the pipeline, reduce the movement fluctuation of the instrument warehouse along the pipeline axis, ensure that the pipeline detection sensor is equidistant from the inner wall of the pipeline, and reduce the distance fluctuation between the pipeline detection sensor and the inner wall of the pipeline. Provide...
