Description

Technical Field

[0001] The utility model belongs to the technical field of measurement and metrology, and in particular relates to a device for measuring the installation angle of a raised road sign. Background Art

[0002] In recent years, my country's transportation infrastructure construction has achieved remarkable achievements, and the increasingly developed transportation network has contributed to the safe and convenient travel of the people. Traffic safety facilities are a very important part of highway transportation. The process control and quality evaluation of construction directly affect the safety and comfort during use.

[0003] As a traffic safety facility, raised road signs provide road guidance and nighttime warning guidance for road users. The raised road signs are set with colors and retro-reflectors on the interface facing the driving direction to provide drivers with visual guidance and improve driving safety. Therefore, the installation angle of the raised road signs directly affects the performance of the raised road signs, and the detection of the installation angle is increasingly valued by practitioners.

[0004] At present, the detection of the installation angle of the raised road sign is based on the provisions of the specification JTG F80 / 1-2017 "Highway Engineering Quality Inspection and Assessment Standards Volume 1 Civil Engineering". The A side of the angle ruler is close to the vertical line (X) of the design installation axis, and the B side is adjusted to the measuring surface close to the raised road sign. During the adjustment process, the A side of the angle ruler should always be perpendicular to the vertical line (X). At this time, the reading of the angle ruler is the actual installation angle (the starting value is 90°), and the actual installation angle minus 90° is the installation angle deviation.

[0005] In the existing methods for measuring the installation angle of raised road signs, a cross or a sliding cross is required to determine the direction of the line. The instrument is large in size, inconvenient to carry, and cumbersome to operate. The auxiliary tools require human visual judgment, which can easily introduce new errors, resulting in large deviations in the detection results. Summary of the invention

[0022] In order to facilitate the understanding of the present invention, the specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0023] Unless otherwise specified or defined, the "first, second..." used in this article is merely used to distinguish names and does not represent a specific quantity or order.

[0024] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.

[0026] Ideally, the raised road sign 200 should be set parallel to the curb 100, but there are often errors in actual installation, which makes the raised road sign 200 tilted to the curb 100. In this way, the prompt interface of the raised road sign 200 cannot be displayed at the best angle in the driving direction, which is not conducive to driving safety. The utility model is mainly suitable for measuring the inclination angle of the raised road sign 200 relative to the curb 100. According to the inclination angle, it can be judged whether the installation angle of the raised road sign 200 meets the standard. In the prior art, before measurement, auxiliary tools such as a cross or a sliding cross are needed to determine the direction of the line (i.e., the length direction of the road), but the existing auxiliary tools are large in size, inconvenient to carry, and cumbersome to operate. In addition, the auxiliary tools require manual visual judgment, which is easy to introduce new errors, resulting in large deviations in the detection results.

[0027] like Figure 1 to Figure 2As shown, an embodiment of the utility model discloses a device for measuring the installation angle of a protruding road sign, including a positioning assembly and a measuring piece 10, wherein the positioning assembly includes a first baffle 20, a second baffle 30 and a laser sensor 40, the laser sensor 40 is fixed on the measuring piece 10, and the laser emission direction of the laser sensor 40 is parallel to a side edge of the measuring piece 10 which is configured to be close to the curb, and laser marking positions are provided on both the first baffle 20 and the second baffle 30.

[0028] When the laser signal emitted by the laser sensor 40 penetrates the laser mark, it indicates that the measuring piece 10 is parallel to the length direction of the road, that is, the measuring piece 10 is parallel to the driving direction. The laser mark is located at the center or near the center of the first baffle 20 and at the center or near the center of the second baffle 30. Preferably, the first baffle 20 and the second baffle 30 are configured as baffles of the same size, and the laser marks are both located at the center of the baffles. By adopting a separate baffle, distance adjustment is achieved. In actual applications, the farther the distance between the two baffles, the higher the accuracy of the parallel calibration, and the smaller the detection error.

[0029] The laser sensor 40 can be specifically configured as an infrared or ultraviolet laser sensor, and has two bidirectional emission ports 41 for respectively emitting laser signals (such as Figure 1 That is, the laser sensor is provided with two emission ports 41, corresponding to the first baffle 20 and the second baffle 30 respectively, and the laser emission directions of the two emission ports 41 are opposite and located on the same straight line, both parallel to the edge of one side of the measuring piece 10 configured to be close to the curb.

[0030] When in use, the first baffle 20 and the second baffle 30 are placed at intervals on the front and rear sides of the measuring member 10. In addition, the first baffle 20 and the second baffle 30 are placed vertically on the road surface along the length direction of the road, and the planes of the first baffle 20 and the second baffle 30 are respectively perpendicular to the curb 100, and the measuring member 10 is placed between the first baffle 20 and the second baffle 30, and the measuring member 10 is placed between the protruding road sign 200 and the curb 100 for measurement.

[0031] The utility model sends a laser signal to the first baffle plate 20 and the second baffle plate 30 through the laser sensor 40 to achieve long-distance directional positioning, thereby ensuring that the measuring piece 10 is parallelly calibrated in the direction of the road length for measurement, thereby improving the detection accuracy. In addition, the baffle plate is small in size and easy to carry. Compared with determining the direction of the road length through larger auxiliary tools such as a cross or a sliding cross, the operation can also be simplified.

[0032] In this embodiment, the measuring member 10 includes a support base 11 and an angle ruler, the laser sensor 40 is fixed on the support base 11, and the laser emission direction of the laser sensor 40 is parallel to the side edge of the support base 11 that is configured to be close to the curb, and the angle ruler is slidably connected to the support base 11. The support base 11 can be set to be made of aluminum alloy or stainless steel.

[0033] Furthermore, the angle ruler includes a main ruler 12 and a slave ruler 13, one end of the main ruler 12 is slidably connected to the support seat 11, and the other end of the main ruler 12 is rotatably connected to one end of the slave ruler 13. The main ruler 12 is located above the support seat 11, and the length direction of the main ruler 12 is perpendicular to the laser emission direction of the laser sensor 40. During measurement, when the measuring piece 10 is placed between the protruding road sign 200 and the curb 100, one side edge of the support seat 11 is close to the curb 100, and one side edge of the slave ruler 13 is close to the protruding road sign 200. The sliding connection relationship between the main ruler 12 and the support seat 11 can be flexibly adjusted, which is convenient for use in scenes where the distances between the protruding road sign 200 and the curb 100 are different.

[0034] As an optional embodiment, a connecting member 14 is provided on the support seat 11, and a slot is provided in the connecting member 14, and the main scale 12 is inserted into the slot and can slide in the slot. Only one connecting member 14 that is long enough to fix the main scale 12 can be provided, or at least two shorter connecting members 14 can be provided, at least two connecting members 14 are distributed at intervals, and at least two connecting members 14 are distributed in the length direction of the connecting member 14. Among them, the connecting member 14 can be fixed to the support seat 11 by welding, and the main scale 12 is installed in the slot to achieve a slidable connection.

[0035] In this embodiment, a plurality of supporting feet 15 are disposed at the bottom of the supporting base 11. The number of the supporting feet 15 is set to at least three, preferably four, and distributed below the four corners of the supporting base 11.

[0036] In order to further improve the horizontality of the support seat 11, preferably, an adjustment member 16 is provided at one end of each support foot 15, and the adjustment member 16 is movably connected to the support foot 15, and the adjustment member 16 abuts against the support seat 11 to adjust the height of the support foot 15, thereby ensuring the horizontality of the support seat 11. Specifically, a plurality of through grooves may be provided on the support seat 11, corresponding to a plurality of support feet 15, respectively, and the through grooves penetrate the support seat 11, and the support feet 15 are located in the through grooves. Among them, the adjustment member 16 can be located below the support seat 11, or it can be located above the support seat 11. Preferably, the adjustment member 16 is located above the support seat 11, which is convenient for the operator to adjust.

[0037] For example, the support foot 15 is specifically configured as a screw rod, and the adjustment member 16 is specifically configured as a nut, which is screwed onto the screw rod. The head of the screw rod is located below the support seat 11, the screw rod passes through the support seat 11 and is located in the through slot, the tail of the screw rod is located above the support seat 11, and the nut is sleeved on the tail of the screw rod and is located above the support seat 11. The height of the screw rod can be adjusted by tightening or loosening the nut, thereby achieving the leveling of the support seat 11.

[0038] Preferably, in this embodiment, a level bubble 17 is also provided on the support base 11, such as a common long bubble, a compartment long bubble, a compensation long bubble, a glass round bubble, a metal round bubble, an electronic bubble, an electronic compensator, a plastic level bubble 17, etc. The main purpose of the level bubble 17 is to provide a visual reference to help the operator quickly and accurately determine whether the support base 11 is in a horizontal position, thereby ensuring the accuracy of the measurement result. When the bubble in the level bubble 17 is located in the center of the center line of the ruler, it means that the support base 11 has been adjusted to a horizontal level.

[0039] The method for detecting the installation angle of the raised road sign 200 provided by the present invention is performed according to the following steps S1 to S4:

[0040] S1. Place baffles within a range of 1-2 m in front and behind the protruding road sign 200 to be detected along the length direction of the road, with the edges of the baffles close to the curb 100 and the surface of the baffles perpendicular to the edge of the curb 100; and place a measuring piece 10 between the protruding road sign 200 and the curb 100, with the side of the measuring piece 10 close to the edge of the curb 100.

[0041] S2. Turn on the infrared laser sensor 40 and fine-tune the position of the measuring member 10 so that the front and rear infrared rays pass through the center lines of the front and rear baffles respectively.

[0042] S3, sliding the main scale 12 of the angle ruler to make the slave scale 13 close to the protruding road sign 200, so that the connection between the main scale 12 and the slave scale 13 contacts one side edge of the protruding road sign 200.

[0043] S4. Rotate the secondary scale 13 of the angle ruler so that the secondary scale 13 is in close contact with the side of the raised road sign 200, and read the angle value (°) of the angle a between the primary scale 12 and the secondary scale 13, that is, obtain the installation angle of the raised road sign 200.

[0044] In summary, compared with the existing device for detecting the angle of raised road signs, the implementation of the embodiment of the utility model can improve the detection accuracy and make the operation more convenient by positioning and calibrating the laser sensor and utilizing a high-precision infrared laser to realize long-distance determination of the driving direction. Moreover, by installing a slidable universal angle ruler, the angle detection of raised road signs in different scenarios can be adapted.

[0045] The above embodiments are not exhaustive enumerations based on the present invention, and there may be multiple other implementations not listed. Any replacement and improvement made without violating the concept of the present invention shall fall within the protection scope of the present invention.
