Description
Technical field
The present invention relates to survey instrument, relate in particular to cylindrical measurement instrument and measuring method thereof.
Background technology
The circular lower prop of the heavy duty steel-structure factory building of industries such as metallurgy, shipbuilding recycles distortion such as often producing inclination down at dynamic loads such as driving liftings for a long time, mill construction is produced extra-stress, be unfavorable for the normal carrying of mill construction, also cause simultaneously the factory building driving to produce the click rail, gnaw phenomenon such as rail, influence the normal operation of relevant devices such as track serviceable life and driving.For in time, correctly grasp the circular lower prop distortion of steel-structure factory building situation, in the detection of mill construction reliability and evaluation and industrial building structure condition managing, be one of important detection content to the circular lower prop inclination measurement of steel-structure factory building.In the circular lower prop inclination measurement of steel-structure factory building process, because the site work regional space is narrow in the factory building, light secretly a little less than, the equipment component domain oscillation is big, have the adverse condition of many measurements such as hot gas, often can't satisfy the normal condition that adopts surveying instruments such as setting up transit that circular lower prop is tilted to measure, and when adopting the transit survey cylinder to tilt, efficiency of measurement is lower.For this reason,, research and develop novel cylinder tiltmeter voluntarily in conjunction with on-site actual situations, and through the scene repeatedly application obtain good result.
Measure the classic method that cylinder tilts
Measuring appliance: transit, straight steel ruler
Measuring method:
Vertical identity distance cylinder 5～10m place, ground with tested vergence direction is provided with a transit at factory building circular steel lower prop, it is same as the horizontal shift value of ground crest line upper end observation station with respect to the bottom observation station to utilize transit and straight steel ruler measurement to be positioned at cylinder, determine good vergence direction simultaneously, and carry out record.
Measure shortcoming:
The site work regional space is narrow in the factory building, light secretly a little less than, easily produce measured deviation; Part cylinder near zone ground does not have the space of the transit survey of setting up, and causes can't measuring cylinder herein.
Big, the adverse condition that has many measurements such as hot gas of equipment component domain oscillation in the factory building during transit can't normally be put, leveling, does not possess the normal condition that adopts surveying instruments such as setting up transit that circular lower prop inclination is measured in this zone.
When adopting the transit survey cylinder, because the restriction of cylinder structure itself is difficult to accurately, finds fast with the corresponding outermost crest line of tested vergence direction; In operation, generally need 3 people, measuring every post needs 4 minutes approximately, and the activity duration is long, efficiency of measurement is low.
Summary of the invention
The present invention is intended to solve the above-mentioned defective of prior art, and a kind of column gradient measuring device is provided.The present invention makes operating personnel at the scene under the complex environment, can be quick and easy, correctly carry out the operation of cylinder inclination measurement, shortened the site work time, and reduced operating personnel, surveying work efficient is improved significantly.
The present invention is achieved in that
