Embodiment 1

[0022] see Figure 1-5 , an adjustable crawler-type pipeline magnetic leakage detection device, including a base 7, a detection device 17 and a carrying mechanism, the detection device 17 is rotated and arranged on one side of the base 7; the carrying mechanism is on the base Four groups are arranged on the 7 and the interval between adjacent ones is 90 degrees; the carrying mechanism includes a support 5, a rotating support 2, a belt 8 and an adjustment wheel 12; On the seat 7, the rotating bracket 2 is hinged with one end of the bracket 5, and then the distance between the carrying mechanism and the base 7 is further adjusted by adjusting the angular position of the bracket 5; There is an adjustment wheel 12, and a belt 8 is installed on the outside of the adjustment wheel 12, and then by driving the rotation of the belt 8, the device can move and walk on the inner wall of the pipeline 1.

[0023] Further, the specific structure of the cross-section of the belt 8 is not lim...

Embodiment 2

[0030]In order to further improve the operation effect of the device, this embodiment has made the following improvements on the basis of the first embodiment. A telescopic rod 14 is slidingly installed, and a spring 15 is connected between one end of the telescopic rod 14 and the inner wall of the telescopic groove 13. , so that the belt 8 has the ability to adjust while expanding and tightening, which further improves the operation effect and operation stability of the device.

[0031] The working principle of this embodiment: by rotating the adjustment wheel 12 and installing it on the telescopic rod 14, and then under the thrust of the spring 15, the belt 8 has the ability to adjust while expanding, which further improves the operation effect of the device and operational stability.

Abstract

The invention discloses an adjustable crawler-type pipeline internal magnetic flux leakage detection device, which includes a base, a detection device and a carrying mechanism. The detection device is arranged on one side of the base in rotation, and the carrying mechanism is on the base. A total of four groups are arranged and the interval between adjacent ones is 90 degrees; the carrying mechanism includes a bracket, a rotating bracket, a belt and an adjusting wheel. The distance between the carrying mechanism and the base is further adjusted by adjusting the angular position of the bracket. By setting the slider and adjusting the spring, under the thrust of the adjusting spring, the slider drives the connecting rod to further push the bracket so that the belt and the pipe The inner wall of the belt is in conflict with each other, thereby realizing the radial self-adjustment ability of the device; by setting the expansion wheel on the slider and the guide wheel on the base, the belt expansion force of the belt pair is compensated, and the belt pair The belt runs more smoothly.

Description

technical field [0001] The invention relates to the field of pipeline detection, in particular to an adjustable crawler-type pipeline internal magnetic flux leakage detection device. Background technique [0002] Pipeline transportation has been widely used in the fields of power generation, metallurgy, petroleum and chemical industry, and is an important part of modern urban construction. During the use of the pipeline, along with the influence of the environment and the corrosion of the transport medium, crack corrosion holes and potential hole defects appear on the pipeline. If these defects are not further treated, it is easy to cause subsequent medium leakage; thus causing waste of resources and environmental pollution. Today, damage to the inner wall of a pipe can be detected by the magnetic flux leakage method. [0003] As far as the present is concerned, the existing pipeline magnetic flux leakage detection device has a cumbersome adjustment process for pipe diamet...
