Pipe composite-motion driving device

Abstract

The invention provides a pipe composite-motion driving device which relates to a pipe analyzing and measuring technology and comprises a pedestal (2), a V-shaped supporting seat (5) and a friction driving wheel (6). The V-shaped supporting seat (5) is fixedly installed on the pedestal (2). The friction driving wheel (6) is installed on a driving-wheel installing plate (4). One side of the driving-wheel installing plate (4) is hinged with the top edge of the V-shaped supporting seat (5), and the driving-wheel installing plate (4) covers the V-shaped supporting seat (5). A measured pipe (7) is longitudinally placed in the V-shaped supporting seat (5), and the top of the pipe is protruded from the upper end surface of the V-shaped supporting seat (5); and the friction driving wheel (6) is pressed on the measured pipe, and the axial line of the friction driving wheel (6) and the longitudinal axial line of the measured pipe (7) form an acute angle. The friction driving wheel (6) is driven,and the measured pipe (7) makes spiral type composite motion through friction driving. The device can be used for rapidly and continuously measuring the wall thickness by being combined with a wall-thickness measuring device, the efficiency is high, and the measuring result is reliable.

Description

technical field [0001] The invention relates to the technical field of analyzing and measuring the physical and mechanical properties of pipes, and furthermore, relates to a device for driving pipes when measuring the wall thickness of pipes. technical background [0002] With the rapid development of the plastic pipe industry, its application fields continue to expand. At present, it has been widely used in urban water supply and drainage, building water supply and drainage, hot water supply, heating and heating, building rainwater drainage, urban gas, agricultural irrigation and drainage, and chemical fluid transportation. And wire, cable sheathing tube and other fields. In the development and production of plastic pipes, accurate performance evaluation is very important for the safety and reliability of pipes in use. In the performance evaluation project of the pipe, there are a large number of projects that need to measure the wall thickness of the pipe and find out the...

Problems solved by technology

In the performance evaluation project of the pipe, there are a large number of projects that need to measure the wall thickness of the pipe and find out the minimum value of the wall thickness at the same time. A large amount of data needs to be collected during the test, so a large number of samples are required. For so many samples To measure its wall thickness and accurately find out the minimum wall thickness value of each sample, it is not only inefficient but also difficult to find the minimum wall thickness value if conventional measurement methods are used

At present, the commonly used wall thickness measurement devices are hand-held measuring tools. Measuring the wall thickness of pipes with this kind of measuring tool can only be measured at selected points, and continuous measurement cannot be achieved. It is very difficult to find the minimum value of the wall thickness on a sample, and because it is Handheld operation, very inefficient
