Embodiment 1

[0044] like Figure 1-4 As shown, the embodiment of the present invention discloses a worm gear type detection probe carrying device, which is sleeved on the oil pipe 5 placed vertically on site, and includes: a frame 1, a driving wheel mechanism 2, a driven wheel mechanism 3 and a power mechanism 4;

[0045] The frame 1 is a semi-open structure, which is composed of a first semi-cylindrical frame structure 11 and a second semi-cylindrical frame structure 12 to form a whole cylindrical frame structure; an electromagnetic flaw detection probe 6 is installed on the outer upper end of the frame 1;

[0046] The driving wheel mechanism 2 comprises a first driving wheel support seat 21, a second driving wheel support seat 22, a first driving wheel end cover 23, a second driving wheel end cover 24, a driving wheel roller 25, a driving wheel shaft 26 and a worm wheel 27, the driving wheel The axial direction of the wheel shaft 26 is horizontal and one end of the driving wheel shaft 2...

Embodiment 2

[0058] The structure of the worm gear type detection probe carrying device in this embodiment is basically the same as that in Embodiment 1, the difference is that there are three driven wheel mechanisms 3 in this embodiment, including a main driven wheel mechanism and a set of auxiliary Passive wheel mechanisms, such as figure 1 As shown, the main driven wheel mechanism is opposite to the position of the driving wheel mechanism 2 in the frame 1, and the remaining auxiliary driven wheel mechanisms are installed in pairs on the first semi-cylindrical frame structure 11 and the second semi-cylindrical frame structure 12, and are aligned with the main The installation positions of the passive wheel mechanism and the driving wheel mechanism 2 correspond up and down and have a certain distance.

[0059] On the basis of the above technical solution, multiple sets of auxiliary driven wheel mechanisms can also be provided, and the installation positions of each set of auxiliary driven...

Abstract

The invention discloses a worm and gear type detection probe carrying device and an oil pipe field electromagnetic flaw detection method. The worm and gear type detection probe carrying device comprises a frame, a driving wheel mechanism, a driven wheel mechanism and a power mechanism, wherein the frame is formed by splicing a first semicircular cylinder frame structure and a second semicircular cylinder frame structure; an electromagnetic flaw detection probe is mounted at the upper end of the outer side of the frame; the driving wheel mechanism comprises a first driving wheel supporting base, a second driving wheel supporting base, a first driving wheel end cover, a second driving wheel end cover, a driving wheel roller, a driving wheel shaft and a worm wheel; the driven wheel mechanism comprises a first driven wheel supporting base, a second driven wheel supporting base, a first driven wheel end cover, a second driven wheel end cover, a driven wheel roller and a driven wheel shaft; and the power mechanism comprises a motor mounting base, a stepping motor and a worm. According to the worm and gear type detection probe carrying device, the function of field flaw detection of the oil pipe while lifting the oil pipe in the process of lifting the oil pipe in oil well workover treatment is realized, and the oil pipe damage detection efficiency is obviously improved.

Description

technical field [0001] The invention relates to the field of on-site non-destructive testing of oil extraction pipes in the oil exploitation industry, and more specifically relates to a worm gear type detection probe carrying device and an on-site electromagnetic flaw detection method for oil pipes. Background technique [0002] During the production process of the oil well, the oil casing buried in the formation will be damaged or damaged due to eccentric wear or corrosion. Regular damage detection of the oil pipe is required. If the oil pipe damage is not found in time and corresponding measures are taken, the oil well will be damaged normally. Production has a serious impact. [0003] The current tubing flaw detection method is to take the tubing out of the formation after the oil well workover operation, transport the tubing to the maintenance workshop, clean it first, and then perform flaw detection. This detection method has the disadvantages of long detection period a...
