Description

Technical Field

[0001] The utility model relates to the technical field of road safety facilities, in particular to a device for measuring the installation angle of a contour mark. Background Art

[0002] As a driving sight guidance facility, delineators are often used to display the boundary contours of roads and guide vehicles to drive normally. Because they will present a retro-reflective light source under the illumination of vehicle lights, drivers can see the direction of the road ahead in dim light and weak lighting at night, thereby ensuring traffic safety. However, when delineators are installed, whether the angle between the reflective surface and the center line of the road is correct and meets the requirements of the specifications directly determines whether the driver can clearly grasp the actual road direction through the reflected light source of the delineator.

[0003] At present, domestic specifications clearly define the inspection and testing methods for contour mark angles and the instruments used, such as flower rods, crosses, tape measures, universal angle rulers, etc. However, the measurement methods are cumbersome, inefficient, and low in precision. In addition, due to manual operation errors and instrument deviations, it is difficult to ensure the accuracy of the contour mark installation angle.

[0004] In view of this, in order to solve the above problems, the utility model patent provides a contour mark installation angle measuring device. Utility Model Content

[0010] The leveling telescopic frame comprises a leveling base and a telescopic rod. The bottom of the leveling base is provided with at least three telescopic legs, and the telescopic rod is vertically installed on the top of the leveling base.

[0011] Furthermore, the laser instrument mounting frame is "L"-shaped, and the two laser rangefinders are respectively arranged on two mutually perpendicular support rods of the "L"-shaped laser instrument mounting frame.

[0012] Furthermore, the laser instrument mounting frame is "T"-shaped, and the two laser rangefinders are respectively arranged on any two mutually perpendicular support rods of the "T"-shaped laser instrument mounting frame; another laser rangefinder is also installed on the remaining support rod of the "T"-shaped laser instrument mounting frame, and the other laser rangefinder is perpendicular to the laser rangefinder on the middle support rod of the "T"-shaped laser instrument mounting frame, and emits laser in the horizontal direction toward the outside of the laser instrument mounting frame.

[0013] Furthermore, a level bubble is provided on the top surface of the leveling base.

[0014] Furthermore, the laser instrument mounting bracket can be horizontally rotatably arranged on the top of the telescopic rod of the corresponding leveling telescopic bracket.

[0017] Furthermore, the telescopic rod in the laser measurement assembly is arranged close to one edge of the leveling base, so that the laser instrument mounting frame is close to the edge of the leveling base or partially extends out of the edge of the leveling base.

[0021] Step S2, making two laser rangefinders emit lasers toward the opposite side of the road respectively along the normal direction and tangential direction of the luminous surface of the contour mark to be measured;

[0022] Control one of the laser rangefinders on the laser mounting bracket to be perpendicular to the luminous surface of the contour mark to be measured, and the other laser rangefinder to be naturally parallel to the luminous surface of the contour mark to be measured; turn on the two laser rangefinders, and keep the lasers of the two laser rangefinders on the laser mounting bracket facing the opposite side of the road;

[0026] First, calculate the angle α1 between the laser emitted along the normal direction of the light-emitting surface and the line connecting the two laser receiving components. Since the beams of the two lasers and the line connecting the two laser receiving components form a right triangle, the value of the angle α1 is obtained according to the tangent function tanα1=L1 / L2;

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0041] like Figures 1 to 3 As shown, a device 100 for measuring the installation angle of a contour mark of the present invention is used to measure the installation angle of a contour mark 200 .

[0042] The measuring device 100 comprises a laser measuring component 10 and two laser receiving components 20. The laser measuring component 10 is used to emit laser light, and the laser receiving component 20 is used to receive laser light and assist the laser measuring component 10 in measuring the distance between the two.

[0043] The laser measurement assembly 10 includes a leveling telescopic frame 1 and a laser instrument mounting frame 2. The laser instrument mounting frame 2 is arranged on the top of the leveling telescopic frame 1. At least two laser rangefinders 3 are arranged on the laser instrument mounting frame 2. The two laser rangefinders 3 are respectively arranged perpendicular to each other and are used to emit lasers 5 in the horizontal direction toward the outside of the laser instrument mounting frame 2. The leveling telescopic frame 1 is set to control the laser instrument mounting frame 2 to maintain its level and adjust its height to match the contour mark 200 at different installation positions.

[0044] The laser receiving assembly 20 includes a leveling telescopic frame 1 and a laser signal receiving board 4, wherein the laser signal receiving board 4 is arranged on the top of the leveling telescopic frame 1; a circular receiving area 41 may be provided on the laser signal receiving board 4 for easy alignment; the laser signal receiving board 4 is controlled to remain horizontal by means of the leveling telescopic frame 1, and is ensured to be at the same horizontal plane at the same height as the laser rangefinder 3.

[0045] Specifically, the leveling telescopic frame 1 includes a leveling base 11 and a telescopic rod 12. At least three telescopic legs 13 are provided at the bottom of the leveling base 11. In this embodiment, four telescopic legs 13 are provided at the bottom of each leveling base 11. The telescopic legs 13 are used to adjust the height of each direction of the leveling base 11. The telescopic legs 13 can adopt a common structure and achieve height adjustment by rotation.

[0046] The telescopic rod 12 is vertically installed on the top of the leveling base 11. The telescopic rod 12 of this embodiment takes the structure in which a telescopic sub-rod 121 and a telescopic outer tube 122 cooperate with each other as an example, but is certainly not limited to this structure; the telescopic sub-rod 121 of this embodiment can be telescoped up and down and inserted into a telescopic chamber (not shown) set on the top of the telescopic outer tube 122, and the side wall of the telescopic outer tube 122 is provided with a locking bolt 123 that penetrates into the telescopic chamber for fixing the telescopic sub-rod 121.

[0047] like Figure 3 As shown, the laser instrument mounting frame 2 can be "L" shaped, and the two laser rangefinders 3 are respectively arranged on two mutually perpendicular support rods 21 of the "L" shaped laser instrument mounting frame 2. The "L" shape can be intuitively and conveniently installed on the laser rangefinder 3 and the laser instrument mounting frame 2. At the same time, the backs of the two brackets of the laser instrument mounting frame 2 are both set as vertical planes 22, and any vertical plane 22 is perpendicular to one of the laser rangefinders 3 and parallel to the other laser rangefinder 3.

[0048] Another example Figure 4 As shown, the laser instrument mounting bracket 2 can also be set to a "T" shape.

[0049] Then, the corresponding two laser rangefinders 3 are respectively arranged on any two mutually perpendicular support rods 21 of the "T"-shaped laser instrument mounting frame 2; that is, one laser rangefinder 3 must be arranged on the middle support rod 21 of the "T"-shaped laser instrument mounting frame 2. If the back of the middle support rod 21 of the "T"-shaped laser instrument mounting frame 2 is set as a vertical plane 22, the laser rangefinder 3 of the middle support rod 21 is perpendicular to the vertical plane 22, and the other two laser rangefinders 3 are parallel to the vertical plane 22.

[0050] Furthermore, another laser rangefinder 3 can be installed on the remaining support rod 21 of the "T"-shaped laser instrument mounting frame 2. The other laser rangefinder 3 is also perpendicular to the laser rangefinder 3 on the middle support rod 21 of the "T"-shaped laser instrument mounting frame 2, and is used to emit laser 5 in the horizontal direction toward the outside of the laser instrument mounting frame 2.

[0051] Therefore, a "T"-shaped laser instrument mounting frame 2 is provided with three laser rangefinders 3, and each laser rangefinder 3 is arranged at 90 degrees between two adjacent ones. When in use, two mutually perpendicular laser rangefinders 3 can be selected to be opened as needed, which can improve measurement efficiency.

[0052] In this embodiment, the telescopic rod 12 in the laser measurement assembly 10 can be arranged close to one edge of the leveling base 11, so that the laser instrument mounting frame 2 can be close to the edge of the leveling base 11 (see Figure 3 and Figure 4 ), or partially extends out of the edge of the leveling base 11 (not shown), which makes it easier for the laser instrument mounting bracket 2 to fit the contour mark 200 to be measured.

[0053] Another example Figure 1 As shown, the top surface of the leveling base 11 may also be provided with a level bubble 14 to assist the telescopic legs 13 in leveling the leveling base 11.

[0054] Furthermore, the laser instrument mounting frame 2 and the laser signal receiving plate 4 can be horizontally rotatably arranged on the top of the telescopic rod 12 of the corresponding leveling telescopic frame 1, so that the laser instrument mounting frame 2 can be close to the luminous surface 201 of the contour mark 200 to be measured, and the circular receiving area 41 of the laser signal receiving plate 4 is aligned with the laser 5. The horizontally rotatable connection method can adopt the existing technology.

[0055] Another example Figures 5 to 8 As shown, the utility model provides a method for measuring the installation angle of a contour mark, mainly by means of the above-mentioned measuring device 100, the installation angle of the contour mark 200 can be measured quickly, accurately and conveniently.

[0056] See also Figure 5 , the specific measurement steps are as follows:

[0057] Step S1, adjusting the laser instrument mounting frame 2 to keep it horizontal and close to the contour mark 200 to be measured on one side of the road;

[0058] Specifically, the laser measurement component 10 is placed at the contour mark 200 to be measured on the fence (attached contour mark) or shoulder (annotated contour mark) on one side of the road, and the telescopic legs 13 of the leveling base 11 are adjusted according to the road condition (the road surface is often uneven and therefore needs to be adjusted) to keep the leveling base 11 level. The levelness of the leveling base 11 can be observed by calibrating the level bubble 14. Of course, if the level bubble 14 is not set, the levelness of the leveling base 11 can be observed with the help of a level calibrator (not shown).

[0059] Then adjust the telescopic rod 12; first loosen the locking bolt 123, and then adjust the height of the telescopic sub-rod 121 to keep the height of the laser instrument mounting frame 2 and the contour mark 200 to be measured at the same level, then tighten the locking bolt 123 to fix the height of the telescopic sub-rod 121 and the laser instrument mounting frame 2; thereby improving the accuracy of the measurement.

[0060] Step S2, the two laser rangefinders 3 are instructed to emit laser light 5 toward the opposite side of the road along the normal direction and the tangential direction of the luminous surface 201 of the contour mark 200 to be measured;

[0061] Specifically, when an "L"-shaped laser instrument mounting frame 2 is used, the back side of a support rod 21 of the laser instrument mounting frame 2, that is, the vertical plane 22, is placed against the luminous surface 201 of the contour mark 200 to be measured, so as to control one of the laser rangefinders 3 of the laser instrument mounting frame 2 to be perpendicular to the luminous surface 201 of the contour mark 200 to be measured, and the other laser rangefinder 3 is naturally parallel to the luminous surface 201 of the contour mark 200 to be measured; and when a "T"-shaped laser instrument mounting frame 2 is used, the back side vertical plane 22 of the middle support rod 21 of the laser instrument mounting frame 2 can be placed against the luminous surface 201 of the contour mark 200 to be measured, and then the two laser rangefinders 3 facing the opposite side of the road are turned on as needed, so as to keep the lasers 5 of the two laser rangefinders 3 on the laser instrument mounting frame 2 emitted in the direction of the opposite side of the road.

[0062] Step S3, placing two laser receiving components 20 on opposite sides of the road, and measuring the beam distance between the lasers 5 emitted by the two laser rangefinders 3 and the corresponding laser receiving components 20;

[0063] Specifically, the two laser receiving assemblies 20 are respectively placed on the fence or shoulder on the opposite side of the road, and the telescopic legs 13 of the respective leveling bases 11 are adjusted according to the road conditions to keep the leveling bases 11 horizontal, and then the telescopic rods 12 are adjusted to keep the laser signal receiving plates 4 of the two laser receiving assemblies 20 and the two laser rangefinders 3 on the same horizontal plane.

[0064] Thereby, the beam distances of the lasers 5 emitted by the two laser rangefinders 3 can be measured respectively. The specific coordination and measurement principle of the laser signal receiving board 4 and the laser rangefinder 3 are prior arts and will not be repeated here. At the same time, the beam distance of the laser 5 emitted along the normal direction of the light-emitting surface 201 is recorded as L1, and the beam distance of the laser 5 emitted along the tangential direction of the light-emitting surface 201 is recorded as L2.

[0065] Step S4, the installation angle of the contour marker 200 to be measured is obtained by calculating the measured propagation distances of the two lasers 5 according to the tangent function and combining the derivation of the theorem of similar triangles;

[0066] First, the angle α1 between the laser 5 emitted along the normal direction of the light-emitting surface 201 and the line connecting the two laser receiving components 20 is calculated. Since the beams of the two lasers 5 and the line M connecting the two laser receiving components 20 form a right triangle, the value of the angle α1 is obtained according to the tangent function tanα1=L1 / L2;

[0067] Secondly, since the installation angle of the contour marker 200 to be measured is the angle between the normal line of the contour marker 200 to be measured and the road center line Z, and the two laser rangefinders 3 are perpendicular to each other and emit two lasers 5 from the luminous surface 201 of the contour marker 200 to be measured on one side of the road toward the opposite side of the road to the two laser receiving components 20, it can be deduced according to the similar triangle theorem that the installation angle α2 is equal to the angle α1;

[0068] Finally, the installation angle α2 of the contour mark 200 to be measured is obtained.

[0069] In summary, the utility model provides a contour mark installation angle measuring device 100 and a measuring method. The measuring device 100 is easy to operate, the measuring method is standardized and reasonable, the measured result is highly accurate, and it is convenient to better carry out the quality inspection and detection of the contour mark installation angle. At the same time, it also has at least the following effects:

[0070] First, there is no need to determine the exact position of the road centerline Z in advance, and the angle (installation angle) between the normal line of the reflective surface of the contour marker 200 and the road centerline can be determined through both sides of the road.

[0071] Second, the method provided by this patent is to measure the installation angle of the contour mark by distance. This method is easy to operate and the results obtained are highly accurate.

[0072] Third, the reflective surface of the contour mark 200 produced by the manufacturer cannot be absolutely flat, so the precise installation angle cannot be measured. However, the back vertical plane 22 of the laser instrument mounting bracket 2 of the present invention can provide a relative vertical plane to ensure the accuracy of the measured angle result.
