Column gradient measuring device and measuring method thereof

Abstract

The invention relates to a measuring tool, in particular to a column measuring tool. A column gradient measuring device comprises a straight steel ruler provided with scales, an upright post, two screw bolts, a telescopic sleeve tube and a tup, wherein the top of the upright post is provided with a joint fixedly connected with one end with large scales of the straight steel ruler; each screw bolt is provided with a screw cap and a spacing piece; the two screw bolts are fixedly connected and penetrates through the straight steel ruler, one screw bolt approaches the end with small scales of the straight steel ruler, and the other screw bolt is positioned on the middle section of the straight steel ruler; the telescopic sleeve tube is arranged in parallel with the straight steel ruler, and one end is fixedly connected with the lower section of the upright post; and the tup is hung on the screw bolt positioned on the middle section of the straight steel ruler through a hanging rope. The invention ensures that operators can fast, conveniently and accurately carry out column gradient measuring work in a complex environment in the field, shortens field work time, reduces the operators, and obviously enhances the efficiency of the measuring work.

Description

technical field [0001] The invention relates to a measuring tool, in particular to a cylindrical measuring tool and a measuring method thereof. Background technique [0002] The circular lower column of the heavy-duty steel structure factory building in metallurgy, shipbuilding and other industries often deforms such as tilting and other deformations under the dynamic load cycle such as driving and lifting for a long time, which produces additional stress on the factory building structure, which is not conducive to the normal bearing capacity of the factory building structure, and also causes Crashing and gnawing on the rails in the driving of the workshop will affect the service life of the rails and the normal operation of the driving and other related equipment. In order to timely and correctly grasp the deformation of the circular lower column of the steel structure factory building, the inclination measurement of the circular lower column of the steel structure factory ...

AI Technical Summary

Problems solved by technology

[0008] The on-site operation area in the factory building is narrow and the light is dim, which is prone to measurement deviation; there is no space for theodolite measurement on the ground near some columns, which makes it impossible to measure the column tilt here

[0009] There are many unfavorable conditions for measurement such as large vibration and hot air in some equipment areas in the factory building. The theodolite cannot be normally centered and leveled in this area, and there are no conventional conditions for measuring the inclination of the circular lower column by erecting theodolite and other measuring instruments.

[0010] When using a theodolite to measure a cylinder, due to the structural limitations of the cylinder itself, it is difficult to find the outermost ridge line corresponding to the measured inclination direction accurately and quickly; in the operation, generally 3 people are needed, and it takes about 4 minutes to measure each column, which is a long time , low measurement efficiency
