Embodiment Construction

[0010] Now combined with the manual figure 1 , attached figure 2 The present invention is further described.

[0011] The feeding propulsion device is composed of a lead screw driving device 1, a solid block 2, a bracket 3, a push rod 4, a lead screw 5, a cover plate 6, an end plate 7, a baffle plate 8, a half-section pipe 9, and a variable-section feeder 11. It is used in conjunction with the magnetic flux leakage detector 10 . Bracket 3 and half-cut tube 9 have arc-shaped cross-sectional shapes. The radius of half-cut tube 9 is smaller than that of bracket 3. Half-cut tube 9 can be placed on bracket 3 and can slide. It is a circular structure with a radius not smaller than the radius of the bracket. The small end is a circular structure with the same radius as the pipeline to be detected. The large end and the small end are connected by a variable-section tube, and the bottom is horizontal. The bracket 3 is horizontally aligned with the variable-section dispenser 11, the...

Abstract

The invention relates to a feeding and propelling device for a pipe internal leakage flux detector. The device is used for feeding pipe internal leakage flux detectors and is composed of a screw drive unit, a fixation block, a bracket, a pushing rod, a screw, a cover plate, an end plate, a retaining plate, a half-open pipe and a variable cross-section feeding unit. The bracket is adjusted to be aligned with the variable cross-section feeding unit, the screw drive unit is started to drive the screw to push the half-open pipe into the variable cross-section feeding unit from the bracket, a drive cup on the leakage flux detector tightly attached to the inner wall of the variable cross-section feeding unit, the pushing rod penetrates a through hole in the retaining plate to abut against the tail end of the leakage flux detector, the screw drive unit is started to rotate in the opposite direction, the screw is drive to pull the half-open pipe out, the pushing rod is withdrawn, and accordingly, feeding of the leakage flux detector can be completed. The device has the advantages of being simple and convenient to operate, small in occupied space and capable of feeding the detector easily.

Description

technical field [0001] The invention belongs to the field of detection of oil and gas transmission pipelines, and in particular relates to a propulsion device for putting in a magnetic leakage detector in a pipeline. Background technique [0002] Oil and gas pipelines need to be inspected after laying and using for a period of time. At present, the internal inspection method is mostly used, that is, the pipeline magnetic leakage detector is put into the inspected pipeline, and it is driven by the pressure difference of gas or liquid to make it in the pipeline. Walk to complete the inspection of the pipeline. Due to the large magnetic attraction force of the magnetic flux leakage detector in the pipeline and its heavy weight, it is very difficult to put the detector into the pipeline. If the detection of the submarine pipeline is carried out, the working space of the offshore platform is narrow and the operation is more difficult. And there is a certain risk. The methods cu...
