A natural gas pipeline robot support and mileage measuring device

Abstract

The invention discloses a natural gas pipeline robot supporting and mileage measuring device. The device comprises a base, a rolling wheel frame, an elastic supporting unit and a speed measuring rolling wheel unit; one end of the base is movably connected with the lower end of the rolling wheel frame, the other end of the base is movably connected with the lower end of the elastic supporting unit,the upper end of the elastic supporting unit is movably connected to the middle part of the rolling wheel frame, a plate rib is arranged on the rolling wheel frame, and through holes are formed in the plate rib; and the rolling wheel frame is movably connected to the upper end of the rolling wheel frame through a fourth pin shaft, a sensor is fixedly installed in the through hole of the plate ribthrough a hexagonal thin nut, and the sensor is right opposite to the outer circumferential surface of a fluted disc. The device has the beneficial effects that (1), a high-rigidity compression spring and a low-rigidity compression spring are combined for use, so that the good supporting performance is achieved, and the abrasion of the pipeline robot leather cup is relatively small; and (2), thespeed measuring rolling wheel unit has floatability, and when the pipeline robot using the device runs in the pipeline, rolling wheels can achieve self-adaption when a welding scar is encountered.

Description

technical field [0001] The invention belongs to the field of oil and gas pipeline pigging and detection, in particular to a natural gas pipeline robot support and mileage measuring device. Background technique [0002] Pipelines have become an important means of transportation for transporting energy such as oil and natural gas. After the pipeline has been in service for a period of time, cracks, leaks and impurity deposits in the pipeline will inevitably appear, which will reduce the efficiency of pipeline transportation, cause oil and gas leakage, and even cause catastrophic accidents. In order to improve the service life and safety of the pipeline, it is necessary to carry out regular inspection and maintenance on the pipeline. As an efficient and accurate fault diagnosis, defect detection, and pipeline maintenance carrier, pipeline robots are being widely used in pipeline cleaning, weld inspection, and defect detection, maintenance, and pigging during pipeline operation...

Problems solved by technology

The traditional pipeline robot device adopts a cup-supported structure, which not only has poor passability of the pipeline robot device and is prone to jamming, but also causes serious wear and tear on the long-distance detection cup. Push the pipeline robot to run

The pipeline robot with cup-supported structure is affected by its own gravity and rubs against the pipeline wall, resulting in uneven wear and tear distribution of the cup, resulting in unstable operation of the pipeline robot device in the pipeline, and inaccurate mileage measurement and positioning
