Description

Horizontal verticality tester

The utility model relates to a kind of building operation and employed horizontal vertical detector of installation work of being used for.

In existing building construction and installation work, general all usage level chis detect the gradient with the controlling level direction, judge the horizontal tilt situation of tested object according to the middle partially situation of air level in the surveyor's staff.But, utilize surveyor's staff to detect and the degree of tilt of control object can only be done qualitative and is difficult to do quantitative test, be difficult to reach desired degree of accuracy on the engineering.In addition, because the air level in the surveyor's staff is the assembly of liquids and gases.Certain sticking slow property is arranged between liquid and the air level glass tube walls,, make bubble be difficult for producing and move, reduced the sensitivity of surveyor's staff the mobile generation resistance of gas.For the detection of verticality, present reasonable method is that the magnetic line of force weighs down determination method, but this method also exists degree of accuracy low, and it is cumbersome to detect operation, and is easy to be subjected to the defectives such as influence of external environment.

The purpose of this utility model is exactly the defective that will overcome above-mentioned prior art, invents a kind of highly sensitively, can not only do qualitative analysis, can also do quantitative test, and the Pingdu of catchmenting detects and the verticality detection is a kind of horizontal vertical detector of one.

The purpose of this utility model is to realize like this, according to level and vertical 90 ° principle each other, the mensuration level is formed a square body with vertical instrument, two face detection level degree up and down, about two face detection of vertical degree, utilize the mechanical gear amplification principle again, the subtle change of degree of tilt is reflected on the well-regulated index dial that has amplified, enable pass is crossed naked eyes and is accurately debated the situation that does not go out degree of tilt and verticality.Horizontal vertical detector of the present utility model mainly comprises shell, border permanent magnet, support, pendant and pendant bar, driving gear set, parts such as index dial and pointer.When be placed on the horizontal vertical detector out-of-level or off plumb testee surface on the time, the be about to leave center line of horizontal vertical detector of pendant center of gravity under the effect of gravity drives the pendant bar and rotates, and forms a α angle with the detector center line.The rotation meeting driven gear group of pendant bar is rotated.Gear set is made up of the gears of 4 different sizes, by their mutual transmission, at last the α angle has been amplified 60 times, and the rotation by pointer is reflected on the index dial.For the purpose of accurately, the gradient adopts ppt to calculate, promptly suppose on the length of 1000mm, and at the vertical gradient amm that raise, Sin α=a/1000 then, α=Sin-1a/1000.Suppose that a gets 1,2,3,4 respectively ..., then the α angle is respectively 0.05729 °, and 0.11459 °, 0.17189 °, 0.22918 ..., the difference of adjacent α angle is approximately a constant 0.05730.

In actual detected, the value at α angle is difficult to accurately measure, if α is amplified 60 times, then this problem will be resolved, and establishes α '=60 α, when α is 1,2,3,4 ... the time, then α ' is respectively 3.4374 °, 6.8754 °, 10.3134 °, 13.7508 ° ..., the difference of adjacent α ' angle is approximately 3.4374 ° of constants.If the value A on the index dial is 1,2,3,4 ..., then its number of degrees are respectively 1 * 3.4374 °, and 2 * 3.4374 °, 3 * 3.4374 °, 4 * 3.4374 ° ..., on index dial, just can more clearly reflect.The A value should be identical with a value, otherwise the horizontal vertical detector is inaccurate.When the verticality of inspected object, testee can be close in a side of this detector, the principle of work of detector is the same with the detection level value of slope.

Describe the utility model in detail below by instantiation.

Fig. 1 is a horizontal vertical detector structural representation.

As shown in Figure 1, the horizontal vertical detector comprises: housing 1, permanent magnet 2, protecgulum 3, index dial 4, cloche 5, pendant 13, pendant bar 7 and pendant axle 6, and gear set 8,9,10 and 11, support 17, gear shaft 15 and needle pivot 16, pointer 12 and braking turn round 14.Pendant 13 is heavier objects, is connected with pendant bar 7 vertical fixing, and pendant bar 7 is rotatably connected by the support 17 in pendant axle 6 and the detector.One square opening is arranged at pendant bar 7 tops, and the top in hole is fixed with a gear segment 8.Gear segment 8 and pinion wheel 10 be toe joint mutually, and gear 10 and gear wheel 9 coaxial being fixed together are rotatably connected on the support 17 by common axle 15.Gear 9 again with gear 11 toe joints together, gear 11 is fixed together with pointer 12 coaxial 16, is bearing on the support 17 by needle pivot 16.The radius of gear segment 8 is greater than the radius of gear 10, and the radius of gear 9 is greater than the radius of gear 10, and the radius of gear 11 is less than the radius of gear 9.Pendant axle 6 and gear shaft 15 and needle pivot 16 all at grade, and this plane is perpendicular to two surfaces up and down of detector." 0 " scale place of index dial 4 overlaps with pendant axle 6.Therefore, when pendant 13 when axle 6 rotates, gear segment 8 also rotates with pendant bar 7, gear segment 8 driven gears 10 and 9 rotate, and rotational angle is amplified 10 times.When gear 9 rotated, driven gear 11 and pointer 12 rotated again, and rotational angle is amplified 6 times again, make pointer 12 can clearly reflect the situation of change of angle on index dial 4.

From as can be seen last, this horizontal vertical detector not only can improve the precision of detection, also can improve the efficient of detection, it is not subjected to the influence of external environment, be not subjected to the restriction of object to be detected size yet, and volume is little, is easy to carry and operates, and helps the levelness and the verticality of object are made qualitative and quantitative analysis.
