Example Embodiment

[0027] Example one

[0028] figure 1 with figure 2 Shows a schematic diagram of the principle of a method for detecting the verticality of a tapered column according to a preferred embodiment of the present invention. The method for detecting the verticality of a tapered column includes:

[0029] Step 1: Fix two square diameter measuring frames 2 on the tapered column 1 up and down. The side length of the lower diameter measuring frame 2 is greater than the side length of the upper diameter measuring frame 2, so that the lower The diameter measurement frame 2 is set on the lower diameter position of the tapered column 1, and the upper diameter measurement frame 2 is set on the smaller diameter position on the tapered column 1. The two diameter measurement frames 2 are Can be separated by a certain distance. When the two diameter measuring frames 2 are set on the tapered column 1, the four sides of the lower diameter measuring frame 2 are parallel to the sides of the upper diamete...

Example Embodiment

[0034] Example two

[0035] Figure 1 to Figure 4 Shows a structural schematic diagram of a device for detecting the verticality of a tapered column according to a preferred embodiment of the present invention, refer to figure 2 , The verticality detection device of the tapered column includes two diameter measuring frames 2, two beams 3, a slider, a dial 6 and a plumb line 4, each diameter measuring frame 2 is square; one of the diameter measuring frames The side length of the frame 2 is greater than the side length of the other diameter measuring frame 2. When testing the verticality of the tapered column 1, the two diameter measuring frames 2 are sleeved on the tapered column 1 in parallel up and down. The four sides of the diameter measuring frame 2 are in one pair, and the midpoint of each side of each diameter measuring frame 2 is in contact with the surface of the tapered column 1, so that the diameter measuring frame 2 is perpendicular to the axis a of the tapered column...

Abstract

The invention discloses a method for detecting verticality of a conical upright post. The method disclosed by the invention comprises the following steps: firstly sheathing two diameter measuring frames on the conical upright post, wherein a middle point of each side of each diameter measuring frame is contacted with the surface of the conical upright post; the sides at one side of the two diameter measuring frames are respectively connected with one end of one cross beam; secondly, marking an o1 point on an upper cross beam and an o2 point on a lower cross beam, wherein distances between the cross beams corresponding to the o1 and o2 and end parts connected with the diameter measuring frames are equal; thirdly, fixing a plumb line at one c1 point on the upper cross beam, hanging one sharp cone at the lower end of the plumb line; horizontally mounting a dial provided with circular scale lines on the lower cross beam with the circle center aligned to one c2 point, wherein the ratio of the distance between c1 and o1 to the distance between c2 and o2 is equal to the ratio of the side length of the diameter measuring frame arranged below to the side length of the diameter measuring frame arranged above; and fourthly, obtaining the verticality of the conical upright post by virtue of the circular scale line pointed by the sharp cone and the distance between the two diameter measuring frames. The method disclosed by the invention has the advantage that the verticality of the conical upright post can be accurately obtained by carrying out measurement once.

Description

technical field [0001] The invention relates to the field of measuring tools, in particular to a detection method and a detection device for the verticality of a tapered column. Background technique [0002] In the "Highway Engineering Quality Inspection and Evaluation Standard" (jtg f80 / 1-2004), the allowable deviation for the verticality of the traffic sign column is ±3mm / m. At present, the commonly used detection tools for the verticality of the traffic sign column are ruler, level or theodolite. These tools are very convenient and accurate when testing the verticality of cylindrical columns, but when testing the verticality of tapered columns whose diameter gradually decreases from bottom to top, it is necessary to evaluate the installation quality of the tapered columns , the use of these existing tools requires multiple changes in the measurement direction and multiple measurements, and it is difficult to ensure a uniform basis for each measurement, which easily leads...
