CN2112138U - Meter for flexibility of steel tube - Google Patents

Abstract

The utility model relates to a meter for the flexibility of a steel tube, comprising a positioning supporting bracket 1, a fiducial guide rail 5 and a movable measuring bracket 10, besides a touch switch 2, a pulley wheel 3, a transmission line 4, a retarder 6, a data processor 7, a power supply 8, a motor 9 and a rolling and measuring head 11. The rolling and measuring head 11 is fixed on the movable measuring bracket 10 which bridges over the fiducial guide rail 5. When the power supply is switched on, the movable measuring bracket 10 can slide between the transmission line 4 and the positioning supporting bracket 1, via the pulley wheel 3; the fiducial guide rail 5 is very flat and straight. After used by the factory, the utility model has the advantage of high precision; the flexibility of a measured steel tube can be read directly.

Description

Meter for flexibility of steel tube

A kind of tube bending degree measuring instrument.

The detection of tube bending degree is relatively backward always in the metallurgy industry, usually causes the dispute between production manufacturer and the user for this reason.Before the utility model, the measurement of tube bending degree is that the testing staff is placed on one meter long straight steel ruler on the desire survey steel pipe with one, if steel pipe is definitely straight, answer tight to exist between ruler and the steel pipe, if there is buckling phenomenon in steel pipe, the testing staff just weighs the bending status of steel pipe by clearance gauge, it is big therefore to measure difference, and can't directly reflect the reading of tube bending degree.

The purpose of this utility model will be developed a kind of energy correct measurement tube bending degree exactly, and can directly reflect the measuring instrument of tube bending number of degrees value.

Now in conjunction with the accompanying drawings the utility model is illustrated.

Fig. 1 is the utility model synoptic diagram under detected status.

1 is locating support among the figure, and 2 is contact-making switch, and 3 is pulley, and 4 is transfer line, and 5 is basic guide rail, and 6 is speed reduction unit, and 7 is data processor, and 8 is power supply, and 9 is motor, and 10 is movable measurement bay, and 11 is the tolling measurement head, and 12 is tested steel pipe.

Two locating supports 1 are used for locating tested steel pipe 12, basic rack 5 should be very straight, movable measurement bay 10 straddles on the basic rack 5, when motor 9 is connected with power supply 8, movable measurement bay 10 can slide by the basic rack between locating support 15 by the mechanical movement of pulley 3 and transfer line 4, and decelerator 6 is connected with motor 9, and contact-making switch 2 is fixed on the locating support 1, its effect is to cut off and starter 3, and pulley 3 is fixed on the locating support 1. Tolling measurement head 11 is fixed on the movable measurement bay 10, and it is that a kind of commercially available digital display is long The degree meter, when movable measurement bay 10 slides along guide rail 5, gage outfit 11 is just pasting the surface of tested steel pipe 12 and is rolling, if tested steel pipe 12 is the same very straight with guide rail 5, work as so gage outfit 11 between locating support 1, when pasting the steel tube surface rolling, the digital display lengths table also is that gage outfit 11 is just indicated on a numeral always, if the interior buckling phenomenon that exists of the distance of tested steel pipe 12 between locating support 1, so, when gage outfit 11 is pasting the steel tube surface rolling between locating support 1, the digital display lengths table also is that gage outfit 11 will demonstrate the variation on the height orientation, gage outfit 11 links together with data processor 7, therefore just can directly reflect the measurement result of gage outfit 11 on data processor 7 by circuit conversion, whether the flexibility that the testing staff can judge tested steel pipe immediately meets the standard code requirement.

Of the present utility model being characterised in that, except including contact-making switch 2, pulley 3, transfer line 4, decelerator 6, data processor 7, power supply 8, motor 9, outside the tolling measurement head (digital display type length meter) 11, also include locating support 1, basic rack 5, movable measurement bay 10, said tolling measurement head 11 is to be fixed on the movable measurement bay 10, movable measurement bay 10 straddles on the basic rack 5 behind the plugged, can slide between locating support 1 by the mechanical movement of pulley 3 and transfer line 4, and basic rack 5 is very straight.

The utility model is after the our factory uses, because the flexibility that on data processor 7, can directly read tested steel pipe, therefore the testing staff can judge the whether conformance with standard regulation requirement of tested steel pipe immediately, and got rid of human factor when measuring fully, thereby measure accurately, also avoided and the client between unnecessary dispute.

Claims (1)

1, a kind of tube bending degree measuring instrument, it includes contact-making switch (2), pulley (3), transfer line (4), speed reduction unit (6), data processor (7), power supply (8), motor (9), tolling measurement head (digital display linear measure longimetry table) (11) is characterized in that, also include locating support 1, basic rack (5), movable measurement bay (10), said tolling measurement head (11) are to be fixed on the movable measurement bay (10), movable measurement bay (10) straddles on the basic rack (5), after the energized, can pass through the mechanical motion of pulley (3) and transfer line (4) and slide between locating support (1), basic rack (5) should be very straight.
