[0032] Reference Figure 1-Figure 11 The present invention proposes a municipal building verticality measuring device, including a T-shaped frame 1, a mounting plate 2 and a measuring rod 3. The T-shaped frame 1 is horizontally mounted on a wall, a level bubble 4 is fixedly mounted on the T-shaped frame 1, two winding shafts 5 are rotatably mounted on the T-shaped frame 1, a vertical line 6 is wound on the winding shaft 5, and a hanging weight 7 is fixedly connected to the end of the vertical line 6; when measuring the verticality of a building, the T-shaped frame 1 is first horizontally mounted on the wall, and the horizontal position of the T-shaped frame 1 is determined by the level bubble 4. At the same time, under the action of gravity, the two hanging weights 7 descend, driving the two vertical lines 6 to be lowered from the winding shaft 5.

[0033] When measuring the verticality of a wall with a traditional plumb line, the gap change between the wall and the plumb line is usually visually observed. However, there is a large error in visual observation. Since the observer usually looks from top to bottom, the viewing angle may cause errors in the observed structure, and it is impossible to accurately measure the verticality of the wall.

[0034] The mounting plate 2 is horizontally mounted on the wall, and a No. 1 level 8 is fixedly mounted on the mounting plate 2. The No. 1 level 8 ensures that the mounting plate 2 is horizontally mounted on the wall, and the mounting plate 2 is located directly below the T-shaped frame 1. The measuring rod 3 is mounted on the mounting plate 2, and a No. 2 level 9 is fixedly mounted on the measuring rod 3. The No. 1 level 8 and the No. 2 level 9 are arranged vertically. An adjusting structure is installed on the mounting plate 2, and the adjusting structure can adjust the position of the measuring rod 3; when the vertical line 6 is hung down, the measuring rod 3 is adjusted to abut against the sides of the two vertical lines 6 through the adjusting structure, and one of the vertical lines 6 is adjusted to be parallel to the wall, and the position between the two vertical lines 6 on the measuring rod 3 is measured, and the length of the two vertical lines 6 between the T-shaped frame 1 and the measuring rod 3 is measured. Since the two vertical lines 6 are hung down, the two vertical lines 6 are arranged parallel to each other, and the measuring rod 3 and the vertical line 6 are arranged vertically, the two vertical lines 6 can form a vertical plane, and the measuring rod 3 and the vertical plane are adjusted to be parallel through the adjusting structure. Arrange the wall in a relatively parallel manner (during the construction process, the wall has not been leveled and powdered, and the positions of the T-shaped frame 1 and the mounting plate 2 are not on the same plane. Although the mounting plate 2 is in a horizontal state, the measuring rod 3 and the vertical plane are not parallel. When adjusting the vertical line 6 to be parallel to the wall, after adjusting the position of the vertical line 6 on the measuring rod 3, it is impossible to ensure that the vertical line 6 and the wall are parallel). Then make a mark on the position of one of the vertical lines 6 against the measuring rod 3, and then adjust the vertical line 6 so that the distance between the top end of the vertical line 6 on the T-shaped frame 1 and the wall is the same as the distance between the bottom end of the vertical line 6 on the measuring rod 3 and the wall (that is, adjust the vertical line 6 and the wall to be arranged relatively parallel). At the same time, measure the length of the vertical line 6 between the T-shaped frame 1 and the measuring rod 3 in the unadjusted position, and the length of the vertical line 6 between the T-shaped frame 1 and the measuring rod 3 in the adjusted position, and then measure the distance between the two ends of the two vertical lines 6, and then calculate the inclination angle of the wall by the Pythagorean theorem.

[0035] like Fig.11 As shown in , assuming that the spacing between the two vertical lines 6 on the T-shaped frame 1 is L, the lengths of the two vertical lines 6 between the measuring rod 3 and the T-shaped frame 1 are H and P respectively, the vertical height between the measuring rod 3 and the T-shaped frame 1 is H, and the spacing between the two vertical lines 6 on the measuring rod 3 is D. At this time, a right triangle is formed, the length of the hypotenuse is P, and the lengths of the two right-angled sides are H and DL respectively. The inclination angle of the wall is calculated based on the above data. The structure is simple and has strong applicability. It is not affected by high temperature, high humidity, strong electromagnetic and other environments, and can accurately measure the inclination of the wall of the building to ensure the construction quality of the building.

[0036] like Figure 3As shown in, a motor 10 is installed on the T-shaped frame 1, and the output shaft of the motor 10 is fixedly connected to the end of one of the winding shafts 5. The ends of the two winding shafts 5 are fixedly connected with gears 11, and the two gears 11 are meshed with each other. The motor 10 drives one of the winding shafts 5 to rotate, and then the two winding shafts 5 are driven to rotate synchronously in opposite directions through the meshing transmission of the two gears 11, thereby completing the synchronous winding and releasing of the two vertical lines 6, thereby ensuring that the length difference of the two vertical lines 6 is small when winding and releasing the lines. An encoding wheel 27 is installed on the T-shaped frame 1. The encoding wheel 27 is used to measure the telescopic length of the vertical line 6. In order to facilitate the determination of the length of the two vertical lines 6 to be released, thereby facilitating calculation, the measuring wheel on the encoding wheel 27 is abutted against a rotating wheel, and then the vertical line 6 is placed between the measuring wheel and the rotating wheel to abut (specifically as shown in FIG. 2 ). Figure 2 As shown in FIG. 1 , when the vertical line 6 passes through the slide, the encoding wheel 27 is driven to rotate, thereby ensuring the length of the vertical line 6.

[0037] like Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown in the figure, the adjustment structure includes a connecting head 12, an adjusting plate 13, a sliding shaft 14, a tensioning assembly and a rotating assembly; the connecting head 12 is fixedly connected to one side of the mounting plate 2, a circular arc groove 15 is provided on the side of the connecting head 12, and a rotating groove slidably matched with the connecting head 12 is provided on one side of the adjusting plate 13, and the sliding shaft 14 is fixedly connected to the inner wall of the rotating groove, and the sliding shaft 14 can slide in the circular arc groove 15; in actual operation, the adjusting plate 13 slides on the connecting head 12, and in the sliding process, the sliding shaft 14 in the rotating groove slides in the circular arc groove 15, and the direction of rotation of the adjusting plate 13 on the connecting head 12 is arranged vertically to the No. 1 level 8, so as to adjust the adjusting plate 13 and the mounting plate 2 to be at the same level.

[0038] The tensioning assembly can fix the position of the adjusting plate 13 on the connecting head 12; the tensioning assembly includes a positioning pin 16, a return spring 17, a driving block 18 and a threaded rod 19; a telescopic hole is provided on the inner wall of the rotating groove, and the positioning pin 16 is slidably installed in the telescopic hole. The outer periphery of the positioning pin 16 is circumferentially connected with a boss, and the inner wall of the telescopic hole is provided with a limiting slide groove that slides with the boss, and the return spring 17 is located in the limiting slide groove. The two ends of the return spring 17 are respectively fixedly connected to the inner wall of the end of the limiting slide groove and the boss, and the return spring 17 can drive the positioning pin 16 to retract in the telescopic hole; an inclined groove that slides with the driving block 18 is provided in the adjusting plate 13, and the end of the positioning pin 16 slides with the inclined surface of the inclined groove of the driving block 18. One end of the threaded rod 19 threadedly penetrates the adjusting plate 13 and abuts against the end of the driving block 18. After the section plate 13 is adjusted to the same level as the mounting plate 2, the threaded rod 19 is rotated again so that the end of the threaded rod 19 pushes the driving block 18 to move downward. When the driving block 18 moves downward, the inclined surface of the inclined surface groove on the driving block 18 and the end of the positioning pin 16 slide and cooperate, driving the positioning pin 16 to move laterally in the telescopic hole, so that the other end of the positioning pin 16 abuts against the inner wall of another arc groove 15, thereby fixing the position of the adjustment plate 13 on the connecting head 12 by friction, thereby ensuring the level of the adjustment plate 13. When adjusting the position of the adjustment plate 13, the threaded rod 19 can be rotated in the opposite direction. Under the rebound effect of the reset spring 17, the positioning pin 16 is driven to retract into the telescopic hole, so that the other end of the positioning pin 16 is disengaged from the inner wall of the arc groove 15, thereby ensuring that the adjustment plate 13 is rotated and adjusted on the connecting head 12.

[0039] like Figure 1 , Figure 4 , Figure 5 , Fig. 9 and Fig.10As shown in the figure, the rotating assembly is installed on the adjusting plate 13, and the rotating assembly is used to adjust the horizontal angle between the measuring rod 3 and the adjusting plate 13. The rotating assembly includes a supporting head 20 and a rotating plate 21; the supporting head 20 is fixedly connected to the side of the adjusting plate 13 away from the mounting plate 2, and the rotating plate 21 is rotatably installed on the supporting head 20, and the measuring rod 3 is slidably installed on the side of the rotating plate 21 away from the supporting head 20, and a slider 22 is slidably installed on the side of the rotating plate 21 close to the supporting head 20, and a threaded cylinder 23 is rotatably connected to the slider 22. In actual situations, the rotation direction between the threaded cylinder 23 and the slider 22 is horizontal, and a semi-threaded rod 24 is threadedly inserted on the threaded cylinder 23, and the semi-threaded rod 24 is rotatably installed on the adjusting plate 13, and the adjusting plate 13 is installed There is a driving rod 25, and the driving rod 25 and the semi-threaded rod 24 are connected through a bevel gear set. The bevel gear set includes two bevel gears, and the two bevel gears are fixedly connected to the ends of the driving rod 25 and the ends of the semi-threaded rod 24 respectively. The two bevel gears are meshed with each other. In actual operation, in order to adjust the measuring rod 3 to be parallel to the vertical plane, the driving rod 25 is rotated, and one of the bevel gears is driven by the driving rod 25 to rotate, and then the other bevel gear and the semi-threaded rod 24 are driven to rotate. Since the threaded barrel 23 cannot rotate longitudinally on the slider 22, the threaded barrel 23 and the semi-threaded rod 24 are threadedly matched, so that the threaded barrel 23 is extended and retracted, thereby controlling the rotating plate 21 to rotate horizontally on the support head 20, and then the rotating plate 21 drives the measuring rod 3 to rotate in the horizontal direction.

[0040] like Figure 1 , Figure 4 and Figure 5 As shown in the figure, there are two measuring rods 3, and the two measuring rods 3 are slidably installed on the side of the rotating plate 21. A limiting groove is provided on the side where the two measuring rods 3 are close to each other. A toggle rod 26 is slidably installed on one of the measuring rods 3, and a scale value is engraved on one of the measuring rods 3. In actual operation, after the positions of the measuring rods 3 are adjusted, the two measuring rods 3 are pressed against each other so that the two vertical lines 6 are located in the limiting grooves of the two measuring rods 3, and then the toggle rod 26 is slid, and one of the vertical lines 6 is toggled by the toggle rod 26 and adjusted to be parallel to the wall.

[0041] 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 according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
