Pipeline track instrument provided with novel logging wheel

Abstract

The utility model relates to a pipeline track gauge with novel distance metering wheels. The pipeline track gauge comprises a pipeline track gauge body, and is characterized in that two distance metering wheel devices are arranged at the center of the rear end of the pipeline track gauge body and consist of the distance metering wheels, brackets, tension springs and a mounting seat; the mounting seat is connected to the center of the rear part of the pipeline track gauge body; one of the brackets is connected to the mounting seat through a shaft pin; the distance metering wheels are arranged at the top ends on the outer sides of the brackets; the middle of each bracket is connected with the corresponding tension spring, and the other end of each tension spring is connected to the front side of the mounting seat. The two distance metering wheel devices are symmetrically arranged on the mounting seat; hall switches are arranged on the brackets; magnetic steel is arranged on the distance metering wheels, has the consistent magnetic direction and is uniformly distributed along the side surfaces of the distance metering wheels. The pipeline track gauge with the novel distance metering wheels has the advantages that the distance metering wheels are not used as straightening wheels, so that the distance metering wheels only bear low and uniform pressure, and precise distance metering data can be acquired.

Description

technical field [0001] The invention relates to a pipeline tracker equipped with a new type of travel wheel. Background technique [0002] The pipeline tracker is a device used to measure the three-dimensional trajectory of the pipeline. It uses the instrument to record the distance traveled at each moment, and the instantaneous distance and the azimuth and elevation angle at this moment can be calculated according to three-dimensional geometry to obtain the micro-segment axis. track. Since the pipeline tracker needs to be pulled through the pipeline, in order to prevent the pipeline tracker from overturning in the pipeline, a supporting mechanism will be set at the front and rear ends of the pipeline tracker, and some current pipeline trackers will be used to save production costs. The taxi wheel that detects the traveling distance of the pipeline tracker is integrated into the righting mechanism and becomes the righting wheel, so that the taxi wheel will be subjected to t...

Problems solved by technology

Since the pipeline tracker needs to be pulled through the pipeline, in order to prevent the pipeline tracker from overturning in the pipeline, a supporting mechanism will be set at the front and rear ends of the pipeline tracker, and some current pipeline trackers will be used to save production costs. The taxi wheel that detects the traveling distance of the pipeline tracker is integrated into the righting mechanism and becomes the righting wheel, so that the taxi wheel will be subjected to the pressure attached to the righting wheel (that is, the taxi wheel) by the pipeline tracker when it is running. , resulting in inaccurate measurement, so in order to obtain accurate measurement data, it is urgent to improve the structure of the taxi wheel installed on the existing pipeline tracker
