[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The device shown is an automatic reading device for quickly detecting the verticality of a traffic sign column 9, comprising a shell 2 having an opening on one side wall and a circular hole at the bottom end of the shell 2. A rotating assembly 3 is disposed within the shell 2, one end of which is connected to the end of the shell 2 away from the opening. A laser rangefinder 1 is disposed on a side adjacent to the opening of the shell 2 and connected to the side wall of the shell 2. A pituitary portion has one end connected to the rotating assembly 3 through the circular hole at the bottom end of the shell 2, and the pituitary portion can rise and / or fall through the rotating assembly 3. In this embodiment, one end of the rotating assembly 3 is fixedly connected to the inner wall of the shell 2.

[0036] In some specific embodiments, the rotating assembly 3 includes a base 31 fixedly connected to the inner wall of the housing 2, with a limit groove 35 provided on the base 31. A support shaft 32 is disposed at an end of the base 31 away from the inner wall of the housing 2 and is fixedly connected to the base 31. A rotating drum 33 is sleeved on the support shaft 32, with a limit post 34 provided at the end of the rotating drum 33 adjacent to the base 31. A rotating knob 4 is disposed at an end of the rotating drum 33 away from the base 31 and is fixedly connected to the rotating drum 33.

[0037] In this embodiment, the rotating drum 33 can be limited by a limiting column 34 that is opened in a limiting groove 35 of the base 31 .

[0038] In some specific embodiments, the rotating knob 4 is provided with anti-slip threads.

[0039] In some specific embodiments, a groove is provided in the length direction of the sleeve.

[0040] In some specific embodiments, the pituitary portion includes: a vertical line 5 and a plumb bob 6. The plumb bob 6 is conical;

[0041] One end of the vertical line 5 is connected to the sleeve, and the other end of the vertical line 5 away from the sleeve is connected to the plumb bob 6.

[0042] In some specific embodiments, the invention further comprises: a magnet 8;

[0043] The housing 2 is provided with a circular groove away from the laser rangefinder 1;

[0044] The magnet 8 is arranged in the circular groove.

[0045] In some specific embodiments, the pituitary portion further comprises:

[0046] The circular level 7 is provided at the top of the plumb bob 6 and is connected to the plumb bob 6 .

[0047] In some specific embodiments, the invention further comprises: a traffic sign column 9;

[0048] The device is adsorbed on the traffic sign column 9 through the magnet 8.

[0049] To raise the bob 6, the rotary assembly 3 is first pulled out of the sleeve along the extension direction of the support shaft 32 from the retaining groove 35 of the base 31. The rotary knob 4 is then rotated to wind the vertical line 5 around the sleeve, thereby raising the bob 6. After raising the bob 6, the sleeve is pushed back into the base 31, locking the retaining post 34 in the retaining groove 35. Conversely, the bob 6 can be lowered.

[0050] Attach the device to the traffic sign post 9, with the plumb line 5 wrapped around the rotating drum 33. Use the rotary knob 4 to move the plumb line 5 up and down until the edge of the plumb bob 6 contacts the sidewall of the post to be measured. Ensure that the level bubble on the circular level 7 is centered. Use the laser rangefinder 1 to measure the distance H between the center of the rotating assembly 3 and the top surface of the plumb line 6. During the measurement process, if the plumb line 5 is insufficient and the plumb line 6 contacts the traffic sign post 9, the level bubble on the circular level 7 will shift. In this case, continue adjusting the length of the plumb line 5 until the plumb line 6 contacts the sidewall and the level bubble on the circular level 7 is centered. Given the maximum radius R of the plumb line 6 and the distance L between the plumb line 5 and the surface of the traffic sign post 9 at the center of the rotating assembly 3, the verticality of the traffic sign post 9 can be calculated using the following formula. Adjust the display settings of the laser rangefinder 1 so that the verticality measurement result of the traffic sign post 9 is directly displayed after the distance measurement.

[0051]

[0052] By adopting the above technical solution disclosed in the utility model, the following beneficial effects are obtained:

[0053] 1. This utility model cleverly converts the distance between the upper end of the vertical line 5 and the column surface into the distance L between the vertical line 5 and the surface of the traffic sign column 9 at the center of the rotation axis. The distance between the lower end of the vertical line 5 and the column surface is converted into the radius R of the plumb bob 6. Both distance L and radius R are fixed values ​​for the equipment, eliminating the need for measurement during each test. On-site, column verticality can be calculated by simply measuring the distance H between the center of the rotation axis and the top surface of the plumb bob 6. This effectively reduces the number of on-site measurement parameters and significantly improves test efficiency and accuracy.

[0054] 2. In this utility model, if the plumb line 5 is insufficiently long during measurement, the plumb bob 6 may contact the traffic sign post 9, causing the bubble in the circular spirit level 7 to shift. By adjusting the plumb line 5 so that the plumb line 6 contacts the side of the post and the bubble in the circular spirit level 7 is centered on the plumb line 6, it can be determined that the plumb line 5 is vertical, reducing manual error.

[0055] 3. The utility model adjusts the display setting program formula of the laser rangefinder so that it automatically calculates and displays the verticality result of the traffic sign column 9 after measuring the distance, thereby reducing the additional manual calculation process and greatly improving the measurement efficiency.

[0056] In summary, the automatic reading device for rapid detection of the verticality of the traffic sign column 9 can effectively eliminate the influence of the swing of the plumb bob 6 or the unstable position of the plumb bob 6 and the ruler during manual measurement on the measurement result, and convert the two measured data into fixed values, thereby greatly reducing the on-site measurement work and making the detection result more accurate. At the same time, by setting the laser rangefinder display program to automatically calculate the measurement results, the rapid and accurate semi-automatic detection of the verticality of the traffic sign column 9 can be achieved.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be considered within the scope of protection of the present invention.
