According to the column declivity measuring device, the column is two-section telescopic sleeve. In the column declivity measuring device, the joint includes a column sleeve sleeved on the top of the column and two side plates arranged on the column sleeve. The large scale end of the steel rule is carried with a pin with two ends fixed with the side plates. In the column declivity measuring device, the minimum scale unit of the steel rule is 1 mm.
Description
Technical field
The utility model relates to survey instrument, relates in particular to the cylindrical measurement instrument.
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 utility model is intended to solve the above-mentioned defective of prior art, and a kind of column gradient measurement mechanism is provided.The utility model 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 do not reduced operating personnel, surveying work efficient is improved significantly.
The utility model is achieved in that
A kind of column gradient measurement mechanism, it comprises the straight steel ruler of a band scale, it also comprises:
High range one end that a column, its top have a joint and a described straight steel ruler is fixedlyed connected;
Two bolts, they respectively carry nut and pad, and two bolt connections also penetrate described straight steel ruler, a close straight steel ruler down scale end, another is positioned at the straight steel ruler stage casing;
A plumb bob, it is suspended on the bolt that is positioned at the straight steel ruler stage casing by lanyard.
Described column gradient measurement mechanism, described column are two joint extension type sleeve pipes.
Described column gradient measurement mechanism, described joint comprise the cylindrical sleeve and two side plates that are positioned on the cylindrical sleeve that are sleeved on the column top, and the high range end of described straight steel ruler has the pin of a fixedly connected side plate in two ends.
Described column gradient measurement mechanism, the least unit scale of described straight steel ruler is 1mm.
Pass through the utility model, solved and utilized the cylinder method of tilting problem such as can't measure in vibration and narrow space environment, make operating personnel at the scene under the complex environment, can be quick, convenient, correctly carry out the operation of cylinder inclination measurement, shortened the site work time, operating personnel have not been reduced, surveying work efficient is improved significantly, therefore, Yan Fa cylinder tiltmeter has obtained using widely in the detection of mill construction reliability and evaluation and the work of industrial building structure condition managing voluntarily, and the plane outer incline value that has been generalized to measurement existing workshop steel roof truss is measured, in the inclination measurement work of existing quick corner, measurement covil construction house and concrete column, obtain good result, and had promotional value widely.
Description of drawings
Below, further specify the utility model in conjunction with the accompanying drawings:
Fig. 1 is the utility model front elevation;
Embodiment
As shown in Figure 1: a kind of column gradient measurement mechanism, it comprises the straight steel ruler 1 of a band scale, it also comprises:
High range one end that a column 3, its top have a joint 31 and a described straight steel ruler 1 is fixedlyed connected;
Two bolts 2, they respectively carry nut and pad, and they are fixedly connected and penetrate 1, one close straight steel ruler 1 down scale end of described straight steel ruler, and another is positioned at straight steel ruler 1 stage casing;
A plumb bob 4, it is suspended on the bolt 2 that is positioned at straight steel ruler 1 stage casing by lanyard 41.
In an embodiment of the present utility model, the least unit scale of described straight steel ruler is 1mm; Described column 3 is two joint extension type sleeve pipes; Described joint 31 comprises the cylindrical sleeve and two side plates that are positioned on the cylindrical sleeve that are sleeved on column 3 tops, and the high range end of described straight steel ruler 1 has the pin of a fixedly connected side plate in two ends.
The cylinder tiltmeter is a measuring principle of utilizing the sash weight collimation method, a kind of special-purpose tiltmeter that combines in conjunction with various professional measuring appliances, its know-why is exactly a bit to hang the plumb bob of suitable weight in tested construction part (cylinder) top expenditure, fulcrum is as the top observation station, make sagging naturally (the approaching more tested member of the plumb bob bottom of plumb bob, its observed reading has whole representative more), get the above 0～20mm place of plumb bob as the bottom observation station; Use straight steel ruler to read or measure horizontal displacement and the sense of displacement (vergence direction) of top observation station with respect to the bottom observation station.
