Technical field
The utility model belongs to science of bridge building checkout equipment technical field, specifically, relates to a kind of Test on Bridge Loading loading position lofting instrument.
Background technology
Along with the progress of science and technology, method for designing and the theory of bridge structure have had the change of essence, but the many uncertain factors affecting science of bridge building quality still exist, for the science of bridge building quality after building up, people more wish to understand and grasp its usability and effect.Now just need to implement dynamic static and moving load experiment to highway bridge, come test design and construction quality and whether meet design and standard criterion requirement, and present stage people mainly assist bevel protractor directly to measure based on meter ruler for the setting-out of loading test loading position, very easily produce comparatively big error in skew bridge, curved bridge and the bridge setting-out process that broadens, the accuracy of test figure is affected greatly.Need a large amount of testing staff to expend more time coordination in the process of setting-out simultaneously to complete.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides the Test on Bridge Loading loading position lofting instrument of the accurate setting-out of a kind of energy.
A kind of Test on Bridge Loading loading position lofting instrument described in the utility model, described loading position lofting instrument comprises flexible main scale 1 with a scale and fixture block 10; Described flexible main scale 1 is connected with another flexible main scale 1 by splicing mouth 2; Described flexible main scale 1 is provided with flexible push rod 6, rotor wheel 3, digital counter 4 and sliding wheel 5 successively from splicing mouth 2 to outside; Described rotor wheel 3 comprises foreign steamer 16, bearing ball 17, fixing interior wheel 18, horizontal slip groove 19 and interior wheel shaft 20; Described flexible main scale 1 in horizontal slip groove 19, and can horizontally rotate around interior wheel shaft 20; Described digital counter 4 is close to outside fixing interior wheel 18; Described sliding wheel 5 can horizontally rotate by the stationary shaft on flexible main scale 1; Described flexible push rod 6 is arranged on inside fixing interior wheel 18 removably, and it is provided with at handle end the control knob 15 that dusts, and this control knob 15 that dusts controls line 14 by dusting and is connected with the valve 8 that dusts of powder tank 7; Described fixture block 10 is located on flexible main scale 1 slidably, and it is provided with fixed angle index dial 12 on top, and is connected with powder tank 7 by the axle 11 that is rotatably connected; Described angle index pointer 13 is fixed on powder tank 7 bottom, and these both sides, powder tank 7 bottom are provided with two conduits 9 that dust.
A kind of Test on Bridge Loading loading position lofting instrument described in the utility model, the range data of described digital counter 4 is respective change along with the rotation of foreign steamer 16.
A kind of Test on Bridge Loading loading position lofting instrument described in the utility model, the fixture block 10 on described flexible main scale 1 and powder tank 7 have multiple.
A kind of Test on Bridge Loading loading position lofting instrument described in the utility model, described in the dust lateral length of conduit 9 can regulate according to actual vehicle wheelspan.
During use, according to loading test result of calculation in advance and design drawing, each loading condition selected is in the axle center loading lateral direction of car under the lengthwise position and each operating mode of bridge both sides guard rail.Determine fixture block and powder tank quantity are installed according to actual demand, digital counter is adjusted to 0, regulate the length of flexible main scale according to bridge orthogonal (oblique) developed width, flexible main scale is overlapped with expansion joint center line, and both sides sliding wheel is close to guard rail.After installing fixture block and powder tank, according to the positive unbalance loading operating mode of reality, powder tank is poured into the powder of different colours, rotation powder tank and conduit rotate around coupling shaft, make angle index pointer and be this bridge oblique angles at angle dial angulation, and pointer and route median perpendicular, regulate each fixture block to move laterally to the calculating position in early stage, make conduit meal outlet position, fixture block both sides and each operating mode load lateral direction of car position of wheel identical.Two testing staff hold the flexible push rod of both sides respectively, and promote rotor wheel, make rotor wheel and guard rail substantially parallel, sliding wheel be close to guard rail advance.When both sides counter range data reaches the lengthwise position of loading condition, halt, press the control knob that dusts, make the valve open that dusts, dust in the vehicle position of wheel of correspondence (such as just carrying vehicle position of wheel spray white, the crimson look in unbalance loading position of wheel).Promote rotor wheel again after dusting, when digital counter range data arrives the lengthwise position of next loading condition, halt, press the control knob that dusts, make the valve open that dusts, dust in the vehicle position of wheel of correspondence.Repetition like this, until it is complete to load vehicle location setting-out.
Compared with prior art, Test on Bridge Loading loading position lofting instrument described in the utility model improves the precision of Test on Bridge Loading loading position setting-out, greatly reduce setting-out required time and testing staff's quantity, improve test efficiency largely, it also has simply, facilitates, is suitable for the features such as various oblique curved bridges simultaneously.
