A building height measuring device is shown in figures 1-5 and comprises a cross beam 1, a base 2, a supporting rod 18, an installation block 23, a first paying-off wheel 14 and a second paying-off wheel 10, wherein one end of the lower surface of the cross beam 1 is connected with the base 2 through the supporting rod 18 which is longitudinally arranged, the other end of the cross beam 1 is fixedly connected with the installation block 23, the first paying-off wheel 14 and the second paying-off wheel 10 are symmetrically arranged on two sides of the installation block, the first paying-off wheel 14 and the second paying-off wheel 10 are identical in shape and size and share a fixing shaft 13, the fixing shaft 13 penetrates through the installation block 23 and is rotatably connected with the installation block 23, two ends of the fixing shaft are fixedly connected with the first paying-off wheel 14 and the second paying-off wheel 10 respectively, a first flexible measuring scale 15 and a second flexible measuring scale 7 are wound on the first paying-off wheel 14 and the second paying-off wheel 10 in the same rotation direction respectively, one end of the first flexible measuring scale 15 is fixedly connected with the first paying-off wheel 14, and the other end of the first flexible measuring scale is connected with a balancing weight 24; one end of the second flexible measuring scale 7 is fixedly connected with the second pay-off wheel 10, the other end of the second flexible measuring scale is connected with a winding mechanism, and the winding mechanism evaluates the descending height of the balancing weight through the length of the second flexible measuring scale 7.

The first paying-off wheel 14 and the second paying-off wheel 10 are respectively wound with a first flexible measuring scale 15 and a second flexible measuring scale 7 in the same rotation direction, and the purposes are as follows: when the second paying-off wheel 10 carries out paying-off action, the first paying-off wheel carries out paying-off action synchronously under the driving of the fixed shaft, and because the two are carried out synchronously, and the shapes and the sizes of the first paying-off wheel and the second paying-off wheel are the same, the paying-off lengths of the first paying-off wheel and the second paying-off wheel are approximately consistent within an error allowable range, therefore, the paying-off length can be evaluated through the length of the take-up of the winding mechanism, the building height can be measured by keeping away from the edge of the building structure, and the measuring safety can be greatly improved. The action of receiving the line to second actinobacillus wheel 10 is accomplished through winding mechanism, and the balancing weight has then played the effect of taut first flexible dipperstick, applys certain degree's torsion for fixed axle 13 simultaneously, makes first flexible dipperstick and the flexible dipperstick of second can keep in the action process with the fastening winding between first actinobacillus wheel or the second actinobacillus wheel, avoids inaccurate because of the not hard up data that lead to. The counterweight block can be in a cubic structure or a common plumb bob structure in specific use.

It should be noted that, when the height of a building is measured, the measuring scale is usually required to be extended out of the outside of the building by a certain distance (because the surface of the building is often provided with a window sill or a convex rib or an air conditioning boss which protrudes outwards), so that the manner of manually holding the measuring scale has certain danger (and the measurement is not accurate because of insufficient extended distance), and the installation block is extended out of the building by a certain distance through the invention without artificial risk.

The single-layer overlapping winding refers to the overlapping winding of the tape measure and not the cable coil, and the advantage of the single-layer overlapping winding is that the lengths of the pay-off output and the take-up output are the same when the fixed shaft rotates for one turn under the condition that the winding turns are the same, so that the aim of improving the measurement accuracy is fulfilled. It should be noted that, when the scales are provided on the first or second flexible measuring ruler, the height of the balancing weight should be considered. For example, the value of the initial scale of the first flexible measuring scale is not 0, but the height value from the bottom end of the balancing weight to the initial scale line; just so can through the high of scale data visual display building on the flexible dipperstick of first to can regard as the contrast of the flexible dipperstick measured data of second, with the precision that detects the measurement.
