Multifunctional pipeline detection device

Abstract

The invention relates to a multifunctional pipeline detection device which comprises a detection rod, a detector, a driving mechanism, a left positioning frame and a right positioning frame. One end of the detection rod is rotatably connected with the left positioning frame; the other end of the detection rod axially penetrates through an inner cavity of a pipeline to be detected so as to be rotatably connected with the right positioning frame; the left positioning frame or the right positioning frame is provided with the driving mechanism; the detector is arranged in the middle of the detection rod; a detecting instrument capable of detecting the flatness of the inner wall of the pipeline to be detected, the precision of a welding seam and the concentricity of the welded pipeline is arranged on the detector; the detecting instrument is connected with detection equipment located outside the pipeline to be detected through signals; a left adjusting device capable of moving up and down to adjust the height of the left end of the detection rod is arranged on the left positioning frame; and a right adjusting device capable of moving up and down to adjust the height of the right end ofthe detection rod is arranged on the right positioning frame. The multifunctional pipeline detection device provided by the invention has the advantages that the detection function is diversified, thedevice can be applied to detection of pipelines with different pipe diameters, and installation and detection are conducted conveniently and efficiently.

Description

technical field [0001] The invention relates to the technical field of manufacturing a pipeline detection device, in particular to a multifunctional pipeline detection device. Background technique [0002] An existing Chinese invention patent application with the application number CN201410709034.8 titled "Pipeline Inner Wall Scale Detection Device" discloses a pipeline inner wall scale detection device, including: a housing, a first detection arm, a second detection arm and a support wheel , the first detection arm and the second detection arm are arranged on the casing, the first detection arm is provided with a screw, and the screw is engaged with a nut fixedly arranged in the casing, and the screw is controlled by a step Driven by a motor, the end of the screw rod is also provided with a travel switch for controlling the opening and closing of the stepping motor, a camera is installed on the second detection arm, and the support wheel is arranged at the bottom of the hou...

Problems solved by technology

However, the device rotates the screw to adjust the extension length of the measurement point to measure the thickness of the scale in the pipeline. It takes time for the screw to retract after extending out of the casing, and continuous measurement along the radial direction of the pipeline cannot be achieved. Moreover, the device is suitable for different The pipe measurement and adjustment of pipe diameter is inconvenient, the application range is small, and the test function is few, so the structure of the device needs to be further improved
