Description
Technical field
The present invention relates to a kind of verticality alignment device and using method thereof, especially relate to and adopt rotation method roller installation verticality alignment device and using method thereof, can widespread use in steel rolling engineering, galvanization production line roller installation process.
Background technology
In steel rolling engineering, hot galvanizing line equipment were installed, roller axis and rolling centerline verticality required less than 0.01mm/1000mm (0.01mm/m).Roller is installed at present looks for the method for verticality to have two kinds: the one, measure the unwrapping wire method, and the 2nd, method of rotation.
Measuring the unwrapping wire method is rolling centerline (vertically) and each roller axial line (laterally) of emitting with transit, set up vertical, horizontal center line support and steel wire, by the messenger wire bob steel wire, roller center line and measuring center line are overlapped, thereby guarantee that roller axis is vertical with rolling centerline.Measure the unwrapping wire method and repeat to set up roller axle to (laterally) center coil holder, waste man-hour, and the centering precision is difficult to reach the specified accuracy requirement entirely with operators'skills and experience because of needs.Method of rotation is that swivel arm is installed on roller, the swivel arm top is a Steel Ruler, and swivel arm can rotate with the roller concentric, with the distance of Steel Ruler measurement with steel wire (rolling centerline), the Rotate 180 degree is surveyed the distance with steel wire (rolling centerline) again, adjusts roller axis according to distance measurement value.Method of rotation largely relies on the sensation of Steel Ruler contact steel wire, and precision is low.Measure line-putting method and not only will repeat to set up transverse center line bracket and steel wire, waste man-hour, increase cost, and the centering precision is very high to operating personnel's technology and experience requirement; It is simple and easy that method of rotation is installed the centering operation, the energy reduction of erection time, but precision is lower, is difficult to reach the requirement of 0.01mm/m.
Summary of the invention
Purpose of the present invention is exactly the problems referred to above that exist at prior art, Steel Ruler in method of rotation range finding is improved, and provide a kind of simple in structure, cost is low, simple and practical, centering precision height and the fireballing rotation method roller installation verticality alignment device of centering.
Another object of the present invention provides the using method of rotation method roller installation verticality alignment device.
For realizing above-mentioned purpose of the present invention, rotation method roller installation verticality alignment device of the present invention by the following technical solutions:
Rotation method roller installation verticality alignment device of the present invention comprises swivel arm, steel wire, the coil holder that is installed on the roller to be measured, steel wire is tensioned on the coil holder of both sides by weight, be characterized in: it also contains screw-thread micrometer and simple and easy series circuit, screw-thread micrometer is installed in the end of swivel arm, described simple and easy series circuit is made of battery, lead, bulb series connection, one end of lead is connected with steel wire, and the other end of lead links to each other with swivel arm, also can directly link to each other with screw-thread micrometer.When the measuring staff of screw-thread micrometer and steel wire were collided, battery, lead, bulb, steel wire and screw-thread micrometer constituted the loop.
For ease of installing and detecting, an end of described swivel arm is a rolling clamp, by bolted on roller to be measured.The other end of lead is to link to each other with the rolling clamp of swivel arm.
The using method of rotation method roller installation verticality alignment device of the present invention is: rotate roller to be measured, make the screw-thread micrometer measuring staff of swivel arm end aim at the position that steel wire A is ordered, rotate screw-thread micrometer, in a single day measuring staff touches steel wire, then produce discharge spark between measuring staff and the steel wire, bulb is connected luminous because of the loop, write down screw-thread micrometer reading value " a ", 180 ° of backward rotation rollers to be measured, make the screw-thread micrometer measuring staff aim at steel wire B point position, same method is write down B point micrometer reading " b ", adjusts the roller axle bearing according to the micrometer reading, and the verticality of the relative steel wire of roller axis is reached: | the requirement of a-b|/AB＜0.01mm/m.Wherein AB is the length of 2 of A, B.
For measuring accuracy, " a ", " b " value are answered duplicate measurements 2-4 time, try to achieve mean value, to reduce the survey measurements error.Best number of times is 3 times.
The present invention is directed to the method for rotation roller relative merits of centering are installed, range finding improves to the Steel Ruler in the method for rotation, introduces simple circuit and screw-thread micrometer, not only simple and practical, and can be easy to reach accuracy requirement, save man-hour, reduce cost verticality centering precision height.
