[0002] According to relevant requirements, the verticality deviation of the columns of roadside equipment (vehicle detectors, weather detectors, closed-circuit television monitoring, etc.) should be ≤5mm / m. Therefore, during the construction of the columns, it is necessary to test the verticality of the columns to ensure that the columns are vertical. Commonly used testing tools include rulers, levels or theodolites. When testing columns of equal diameter, testers often use plumb lines and steel rulers to measure the verticality of the columns.

[0003] However, now more and more electromechanical equipment rods have variable cross-sections, that is, tapered rods. Due to the inclination angle of the rods themselves, the measurement method of the plumb line and the steel ruler cannot accurately measure the verticality of the tapered rods. Utility Model Content

[0030] Reference Figure 1-2 A conical rod verticality measuring device is used for measuring the verticality of rods, in order to facilitate the accurate measurement of the verticality of rods with a conical appearance.

[0031] The tapered rod verticality measuring device comprises a fixing ring 5, a column 1, an auxiliary column 2, a centering mechanism 6 and a laser ranging probe group;

[0032] The fixing ring 5 is sleeved on the outside of the rod to be tested, and a plurality of adjusting screws 501 are arranged at intervals on the fixing ring 5. By rotating the adjusting screws 501, the height between the fixing ring 5 and the ground can be changed, so that the horizontality of the fixing ring 5 can be adjusted on an uneven ground to keep it horizontal. In addition, since a level bubble 502 is provided on the fixing ring 5, the horizontality of the fixing ring 5 can be detected, which facilitates the leveling of the fixing ring 5.

[0033] A concentric moving ring 4 is slidably connected to the fixed ring 5. The column 1 and the auxiliary column 2 are both vertically fixed on the moving ring 4, and the column 1 is opposite to the auxiliary column 2. The column 1 and the auxiliary column 2 can slide around the center of the circle on the fixed ring 5 through the moving ring 4, thereby changing the positions of the column 1 and the auxiliary column 2 outside the rod to be measured.

[0034] A plurality of centering mechanisms 6 are vertically spaced on the column 1, each centering mechanism 6 comprises two cross bars 601 and two centering rods 602, one end of each centering rod 602 is vertically fixed to a cross bar 601, racks 7 are provided on the two cross bars 601, a fixed column is provided on the outside of the column 1, a gear 8 is rotatably connected to the outside of the fixed column through a rotating bearing 9, a plurality of slide rails are horizontally provided on the outside of the column 1, each cross bar 601 is slidably connected to the column 1 through a slide rail, so that each cross bar 601 slides horizontally on the column 1, and because the gear 8 is engaged with the two racks 7, the two cross bars 601 move synchronously in opposite directions. Therefore, when centering is performed, the two cross bars 601 are moved, and the column 1 and the auxiliary column 2 are moved around the rod to be measured through the moving ring 4 until the centering rods 602 on the two cross bars 601 are in contact with the rod to be measured, and the centering is completed.

[0035] There are two groups of laser ranging probe groups, each of which includes two laser ranging probes 3. The two laser ranging probes 3 are respectively arranged on the column 1 and the auxiliary column 2 to respectively measure the distance between the column 1 and the auxiliary column 2 and the rod to be measured. The two laser ranging probes 3 in each group are located on the same horizontal axis. One of the two groups of laser ranging probe groups is arranged at the upper end of the column 1 and the auxiliary column 2, and the other group is arranged at the lower end of the column 1 and the auxiliary column 2, so as to respectively detect the distance between the upper end and the lower end of the rod to be measured, so as to calculate the verticality offset of the rod to be measured per unit length.

[0036] The working principle of the tapered rod verticality measuring device is as follows: first, the fixing ring 5 is put on the outside of the rod to be measured, and then the height between the fixing ring 5 and the ground is changed by adjusting the screw 501 to keep the fixing ring 5 horizontal, and the level of the fixing ring 5 is detected by the level bubble 502 to ensure that the fixing ring 5 is set horizontally;

[0037] Then, the crossbar 601 is moved, and the two crossbars 601 in each centering mechanism 6 are synchronously moved in opposite directions through the rack 7 and the gear 8, so that the two crossbars 601 drive the centering rod 602 to synchronously approach the rod to be measured. At the same time, the column 1 and the auxiliary column 2 are moved around the rod to be measured through the moving ring 4 until the centering rods 602 on the two crossbars 601 are in contact with the rod to be measured. At this time, the centering is completed, and the axis of the rod to be measured is located at the center of the two centering rods 602;

[0038] Finally, the laser ranging probe 3 in the two groups of laser ranging probes detects the distance of the upper and lower ends of the rod to be measured respectively, and obtains the distance between the column 1 and the auxiliary column 2 and the rod to be measured, so as to calculate the verticality offset of the upper and lower ends of the rod to be measured respectively. By combining the verticality offsets of the upper and lower ends of the rod to be measured, the verticality offset of the rod to be measured per unit length can be obtained.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
