Abstract
The utility model discloses a length measuring device for a steel pipe, relates to an auxiliary device for a hydrostatic pressure test of the steel pipe, and solves the problems that the conventional length measuring device is complexly installed and low in measuring accuracy and operation reliability. The length measuring device consists of a roller, a hinged shaft, a connecting rod, a No.1 pin shaft, a base, a tension spring, No.2 pin shafts and a coder, wherein the roller is connected with the connecting rod through the hinged shaft; the connecting rod is connected with the base through the No.1 pin shaft; two ends of the tension spring are connected with the base and the connecting rod through the No.2 pin shafts; and the coder is arranged at the shaft end of the hinged shaft. The length measuring device is used for measuring the length of a spiral welded pipe and a straight welded pipe before a hydraulic pressure test, has the advantages of simple structure and high measuring accuracy, and is convenient to operate.
Description
Technical field
The utility model relates to rolling machinery, particularly on spiral welded pipe, the straight welded pipe production line, and the servicing unit of hydrostatic testing machine.
Background technology
On spiral welded pipe, straight welded pipe production line,, need to be equipped with hydrostatic testing machine in order steel pipe seam to be checked and eliminated welded tube stress; Before the hydraulic testing; For adapting to different steel pipe length, adjust the test unit, steel pipe will obtain the length value of steel pipe before getting into the test unit.
At present, measuring the device of steel pipe length, is at test unit relative position several groups of optoelectronic switches to be set.Its measuring method is following: at first according to the length stepping of the characteristics of testing unit with steel pipe; Steel pipe passes through optoelectronic switch then; When steel pipe through the time, optoelectronic switch just can confirm measured steel tube place length range, adjust hydrostatic testing machine according to this length.The shortcoming of prior art: more complicated when 1, installing needs a lot of group optoelectronic switches; 2, measurement is inaccurate, can only obtain an approximate size scope; 3, the operation unreliable, other article near the time optoelectronic switch also can detect.
The utility model content
The purpose of the utility model is intended to overcome the shortcoming of prior art, and a kind of steel pipe measuring motion is provided, and solves to adopt present measuring motion, and installation is complicated, measurement is inaccurate, move insecure problem.
The utility model is realized through following technical scheme:
A kind of steel pipe measuring motion; It is characterized in that: described measuring motion by: roller, hinge, connecting rod, I bearing pin, base, extension spring, II bearing pin and scrambler are formed; Said roller is connected with said connecting rod through said hinge; Said connecting rod is connected through said I bearing pin with said base, and said extension spring two ends are connected with said connecting rod with said base respectively through said II bearing pin, and said scrambler is installed in the axle head of said hinge.
The utility model compared with prior art owing to measuring motion is installed scrambler at the axle head of roller, and forms pulling force by extension spring to it, and when steel pipe passed through, roller was depressed and rolls along steel tube surface.Scrambler is noted the number of turns that roller rotates, and can calculate girth according to roller diameter, multiply by the exact length that the number of turns just can obtain steel pipe then.The survey that the utility model is used for before the spiral welded pipe, the ERW hydraulic testing is long, have simple in structure, easy to operate, measure advantage accurately.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The utility model is described further through preferred embodiment below in conjunction with accompanying drawing.
Embodiment
As shown in Figure 1; A kind of steel pipe measuring motion; Be made up of roller 1, hinge 1-1, connecting rod 2, bearing pin 3, base 4, extension spring 5, bearing pin 6 and scrambler 7, said roller 1 is connected with connecting rod 2 through hinge 1-1, and said connecting rod 2 is connected through I bearing pin 3 with base 4; Said extension spring 5 two ends are connected with said connecting rod 2 with base 4 respectively through II bearing pin 6, and said scrambler 7 is installed in the axle head of said hinge 1-1.
For roller 1 can have good the contact with steel pipe, bring measuring error with anti-slip, can roller 1 outside surface be pasted one deck polyurethane.
The course of work and the principle of work of the utility model are following:
1, the utility model is installed between the conveyor roller, adjust height (upper surface of roller 1 is a little more than the lower surface 3~5mm) of steel pipe, guarantee steel pipe through the time steel pipe lower surface be close to the upper surface of roller 1;
2, scrambler 7 is installed in the hinge 1-1 axle head of roller 1;
3, when steel pipe passed through, roller 1 was depressed, because the pulling force of extension spring 5 makes roller 1 to roll along steel tube surface, scrambler 7 is noted the number of turns that roller 1 rotates along with steel pipe simultaneously, through calculating the exact length that just can obtain steel pipe.
