Abstract

The utility model discloses a roll gap instrument for measuring a distance between the roll gaps of a continuous casting machine, and relates to an instrument for measuring the opening degree of a continuous casting machine. The instrument comprises a digital display meter component (1), a copper nut (2), a compression spring (3), a movable rod (4), a bottom sleeve (5) and a frame (9) which are connected in sequence; and supporting wheels (6) are fixed on two foots at the bottom part of the frame (6) through a small shaft (8) and an external circlip (7). The utility model can measure the diameter of rolls of 90-600 mm and the dimension of the roll gaps of 60-320 mm. The digital display meter has accurate measurement, and the measuring accuracy thereof can reach 0.01 mm. The utility model has the advantages of simple structure and convenient use and satisfies the demands of practical engineering.

Description

A kind of roll gap meter that is used to measure distance between the conticaster roll gap

Technical field

The utility model relates to a kind of instrument of measuring the conticaster opening degree, relates in particular to a kind of roll gap meter that is used to measure distance between the conticaster roll gap.

Background technology

All needing to use a plurality of rollers in continuous casting installation for casting is provided with in pairs; Roller arranged in pairs, one is referred to as the inner arc roller, and one is referred to as the outer arc roller, and the outer arc roller is fixed, and the inner arc roller can move, and the distance between them is referred to as opening degree.Therefore opening degree is an important indicator in the conticaster, directly influences slab quality, all will measure its opening degree in the conticaster use, and the size of regulating its opening degree by the relative position of regulating the inner arc roller.

The instrument and equipment of existing measurement opening degree mainly contains two kinds:

A kind of is the equipment that contains a plurality of sensors and computer software and hardware, on-line measurement, it is more to measure factor affecting, though measuring speed than very fast, measurement result accuracy is not high, complex structure costs an arm and a leg, and is to use preparing the fan-shaped section spare part.

Another kind is to use original feeler gauge to add vernier caliper, and by manually coming operational measure, not only efficient is low fully, and at the scene because of the restriction in place, the operator uses the feeler gauge inconvenience, causes very easily that the result's is inaccurate.

Summary of the invention

The purpose of this utility model is in order to overcome the existing shortcoming and defect of measuring conticaster opening degree instrument, a kind of roll gap meter that is used to measure distance between the conticaster roll gap to be provided.

The purpose of this utility model is achieved in that

Utilize the characteristic of spring and the tangent characteristic of support wheel and roller, realized the mechanical measurement in roll gap gap, significantly improved accuracy, effectively expanded the scope of application.

Specifically, the utility model comprises digital display meter assembly, copper nut, compression spring, motion bar, bottom sleeves, support wheel, circlip for shaft, little axle and frame;

From top to bottom, digital display meter assembly, copper nut, compression spring, motion bar, bottom sleeves and frame are connected successively; Support wheel is fixed on the bipod of frame bottom by little axle and circlip for shaft.

Principle of work of the present utility model is:

At first adjusting the digital display meter assembly shows, make it to become intermediate value accurately, again this instrument is placed on the roller, make two support wheels and the motion bar roller below contacting at 3, and making the digital display meter motion bar of digital display meter assembly contact another roller by compression digital display meter extension spring, the numerical value that show this moment is exact value.

The utlity model has following advantage and good effect:

1. motion bar can be free movable in the scope of frame and compression spring permission, is applicable to that the opening degree of different roller diameters is measured, and can survey roller diameter 90mm-600mm;

2. subsidiary lengthening threaded rod strengthens the measurement range of roll gap, can survey the roll gap size from 60mm-320mm;

3. measure accurately, digital display meter assembly measuring accuracy can reach 0.01mm.

4. simple in structure, easy to use, satisfy the needs of actual engineering.
