UNIVERSAL PLATFORM ON MAGNETIC WHEELS FOR IN-PIPE DEVICES Russian patent published in 2020 - IPC F16L55/26 F16L101/30 

FIELD: construction.

SUBSTANCE: invention relates to pipeline transport and can be used in designing in-pipe diagnostics devices, as well as other devices used in construction and overhaul of pipelines. Purpose of the present invention is creation of universal platform on magnetic wheels for in-tube devices, which allows: independently get on wheels after possible overturning in pipe and allowing to install on it single unit of in-tube device, which makes it more compact and convenient for internal mounting; manoeuvring in complex piping with DN ≥ 300 mm. Platform comprises magnetic motor-wheel modules, a longitudinal hinge with a rotation limiter connected to the shaft of the geared motor, to perform actions to get it onto the wheels after falling on the side surface in the pipe, additionally comprises lifting platform hoist mechanism, which provides possibility to turn front axle by angle required for magnetization of front axle wheels to pipe surface, and radius surface of roof of in-tube device provides falling to side surface, wherein universal centre of gravity on magnetic wheels is located at its front axis.

EFFECT: proposed universal platform on magnetic wheels for in-tube devices is optimal for construction on its basis of in-tube flaw detectors and other devices, and possibility to independently get on wheels excludes occurrence of extraordinary situations during diagnostic works.
