Description

Technical Field

[0001] The utility model relates to the field of test devices, and particularly to an impact resistance test device for raised road markers. Background Art

[0002] Raised road markers, also known as road studs, are raised marking blocks fixed on the road surface for marking purposes. They are usually used on highways or other roads to mark the center line, lane demarcation lines, edge lines, and to identify dangerous sections such as curves, entrance and exit ramps, guiding markings, road narrowing, and road surface obstacles. Raised road markers can be passive light-emitting type or active light-emitting type, and the latter usually uses solar power supply and emits light through a wireless controller.

[0003] The design and use of raised road markers can improve the visibility and safety of roads, especially at night or in adverse weather conditions. For example, they can provide better retroreflective effects than traditional hot melt markings and will not be flooded by rain even in rainy days, thus maintaining good visibility. In addition, the installation and maintenance costs of raised road markers are relatively low, and they have a long service life.

[0004] To ensure the quality of raised road marker products is qualified, indoor tests need to be carried out before formal construction. The main detection indicators include chromaticity performance, retroreflective performance, overall impact resistance, retroreflective impact resistance, compressive load, etc.

[0005] Among them, according to the relevant regulations of the standard, for the overall impact resistance test of raised road markers, a steel plate with a thickness of not less than 13 mm and an area larger than the lower surface of the raised road marker should be placed on a firm and flat horizontal plane. The raised road marker is placed on the steel plate, and a solid steel ball with a mass of 1040 g ± 10 g is freely dropped from a height of 1 m directly above the raised road marker, and the impact point is the center of the upper surface of the raised road marker. After the raised road marker product undergoes the impact resistance test, there should be no damage in any form outside the area with a diameter of 12 mm centered on the impact point.

[0006] During the test process, due to the steel ball rebounding after hitting the specimen, the situation where the steel ball impacts the specimen multiple times occurs, forming multiple impact points, which has a great influence on the judgment of the test results. To solve this problem, existing impact resistance test devices for raised road markers are provided with a blocking mechanism at the bottom of the steel ball guide cylinder, such as manually driving a blocking rod into the inside of the guide cylinder to prevent the steel ball from impacting the specimen again. This structure is complex and has a high labor intensity. Some also use a driving mechanism to push the specimen away to prevent the steel ball from impacting the specimen again. This structure is complex, has a high manufacturing cost, and may even damage the specimen. In addition, existing impact resistance test devices for raised road markers can only complete the detection of one specimen at a time, and the test efficiency is low. Summary of the Utility Model

[0030] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside and outside that appear or will appear in the text of the present utility model are only based on the drawings of the present utility model, and they do not specifically limit the present utility model.

[0031] See Figures 1-4 , the present utility model discloses an impact resistance test device for raised road markers, which includes a test body 1, a blocking mechanism and a test mechanism. A sample placing platform 11 for placing samples is provided at the bottom of the test body 1.

[0032] The blocking mechanism is arranged at the bottom of the test body 1. The blocking mechanism includes a driving mechanism 2 and blocking blades 3 connected to the driving mechanism 2. The driving mechanism 2 drives the blocking blades 3 to rotate so that the blocking blades 3 cover or open the sample placing platform 11.

[0033] The test mechanism includes at least two groups of test components installed on the top of the test body 1. The test component includes a guide cylinder 4 and a test piece 5. The guide cylinder 4 is a hollow structure that penetrates the upper and lower end faces; the guide cylinder 4 and the sample placing platform 11 are arranged corresponding to each other, and the guide cylinder 4 is placed above the blocking blades 3; the test piece 5 can move along the guide cylinder 4 to fall on the blocking blades 3 or the sample placing platform 11. Among them, the test piece 5 is preferably a steel ball.

[0034] The impact resistance test device for raised road markers of the present utility model is provided with a test body, a blocking mechanism and a test mechanism. The sample is placed on the sample placing platform of the test body, and the test piece falls onto the sample along the guide cylinder to realize the impact resistance test of the sample. When the test piece rebounds after hitting the sample once, the driving mechanism is activated to rotate the blocking blades to the upper part of the sample placing platform to cover the sample placing platform and the sample thereon, preventing the test piece from falling again and hitting the sample, thereby avoiding forming multiple impact points on the sample and facilitating the judgment of the test result. The structure is simple and the test result is accurate. In addition, the number of test components is at least two groups, and at least two samples can be detected in one test, and the test efficiency is high.

[0035] Preferably, the driving mechanism 2 is a voice-controlled motor. The voice-controlled motor controls the transportation of the motor through specific sounds. When the test piece hits the sample, an impact sound is generated, and this impact field triggers the start of the voice-controlled motor to rotate the blocking blades by a certain angle so that the blocking blades move to the upper part of the sample placing platform. When the test piece falls again, it will fall on the blocking blades and will not fall on the sample on the sample placing platform, thereby preventing the test piece from hitting the sample multiple times and making the test result inaccurate. The voice-controlled motor can adopt the existing technical structure and will not be introduced in detail here.

[0036] Preferably, the number of the test components is three groups, four groups, five groups or six groups, but not limited thereto. More preferably, as Figures 1-3 shown, the number of the test components is four groups.

[0037] Specifically, as Figures 1-2 shown, a plurality of sample placing platforms 11 are provided at the bottom of the test body 1, and the sample placing platforms 11 and the guide cylinders 4 are arranged in one-to-one correspondence. That is, each guide cylinder 4 corresponds to one sample placing platform 11, and one sample can be placed on each sample placing platform 11. During the test, the test pieces can be simultaneously dropped from the top to the bottom of the guide cylinders to impact the samples on the corresponding sample placing platforms, and at least two samples can be detected in one test, with high test efficiency. As shown in the drawings, four groups of test components are provided in the present utility model, and the four test pieces are respectively dropped from the four guide cylinders to impact the corresponding samples, so as to complete the detection of four samples in one test.

[0038] Among them, as Figure 2 shown, a leaf placing area 12 is provided between two adjacent sample placing platforms 11, and the driving mechanism 2 drives the barrier blade 3 to move back and forth between the adjacent sample placing platforms 11 and the leaf placing area 12. The numbers of the leaf placing area 12, the barrier blade 3, the sample placing platforms 11, the guide cylinders 4 and the test pieces 5 are the same. Two adjacent sample placing platforms 11 are separated by the leaf placing area 12. In the initial state, the barrier blade is placed in the leaf placing area. The test piece drops from the top to the bottom of the guide cylinder under the guidance of the guide cylinder and impacts the sample in the sample placing platform below the guide cylinder. The test piece rebounds, and the impact sound triggers the start of the voice-controlled motor to rotate the barrier blade, so that the barrier blade moves from the leaf placing area to above the sample placing platform and the sample, that is, below the guide cylinder. When the test piece drops again, it only lands on the barrier blade, thereby avoiding the situation that the test piece impacts the sample multiple times and causing test errors, and ensuring the accuracy of the test structure. After the test is completed, the test piece is taken out from the guide cylinder, and the voice-controlled motor controls the barrier blade to rotate in the opposite direction to reset. Therefore, the barrier blade moves back and forth between the adjacent sample placing platforms and the leaf placing area.

[0039] Preferably, as Figures 1-2 shown, a plurality of limit posts 6 are provided at the bottom of the test body 1, and the height of the limit posts 6 is higher than the height of the barrier blade 3. In order to prevent the movement of the barrier blade from exceeding the moving range, the present utility model also provides limit posts at the bottom of the test body to limit the ranges of the two opposite directions of the movement of the barrier blade. More preferably, limit posts 6 are provided on both sides of a group of adjacent sample placing platforms 11 and the leaf placing area 12. If the barrier blade exceeds the range, it will collide with the limit posts, so that one barrier blade can only move within a group of sample placing platforms and the leaf placing area, thereby ensuring the accuracy of the movement of the barrier blade and further ensuring the accuracy of the test results.

[0040] More specifically, as Figures 1-4As shown, a test inlet 41 is provided at the top of the guide cylinder 4, and a test outlet 42 is provided at the bottom. The test outlet 42 is correspondingly arranged opposite to the sample placement platform 11, and the test outlet 42 is located above the barrier blade 3. The test piece enters the guide cylinder from the test inlet, falls freely, and exits from the test outlet and lands on the sample on the sample placement platform, hitting the sample. Among them, the test outlet is directly opposite to the sample on the sample placement platform. The test outlet is located above the barrier blade to ensure that when the barrier blade rotates above the sample placement platform, it does not interfere with the guide cylinder, and the barrier blade closes the test outlet.

[0041] Preferably, as Figure 1 、 4 shown, a take-out port 43 is provided on the side wall at the bottom of the guide cylinder 4. When the barrier blade rotates and is placed below the guide cylinder, the test outlet is closed. In order to be able to take out the test piece in the guide cylinder, a take-out port is provided on the side wall at the bottom of the guide cylinder, and the test piece can be taken out from the take-out port for the next test.

[0042] Preferably, the axis of the guide cylinder 4 is perpendicular to the plane where the sample placement platform 11 is located, ensuring that the test piece can achieve vertical free fall under the guide of the guide cylinder to ensure the accuracy of the test results.

[0043] Furthermore, as Figure 1 、 3 shown in FIG. -4, the test mechanism further includes a starting component provided at the top of the guide cylinder 4, and the starting component is used to start the test and control the test piece to fall from the top to the bottom of the guide cylinder.

[0044] The starting component includes a starting piece 7 and a limiting piece 8. The starting piece 7 is sleeved outside the guide cylinder 4 and is movably connected to the guide cylinder 4. The limiting piece 8 is movably connected to the guide cylinder 4. A limiting hole 44 corresponding to the limiting piece 8 is provided on the side wall of the guide cylinder 4. The starting piece 7 and the limiting piece 8 are in contact with each other, so that the limiting piece 8 is placed inside the guide cylinder 4 and supports the test piece 5. When the starting piece 7 and the limiting piece 8 are separated, the test piece 5 pushes the limiting piece 8 through the limiting hole 44 and is placed outside the guide cylinder 4, so that the test piece 5 falls into the test outlet 42. Preferably, the limiting piece 8 is hinged to the guide cylinder 4.

[0045] Specifically, the starting piece 7 contacts the limiting piece 8 through the limiting hole 44, so that the limiting piece 8 is placed inside the guide cylinder 4. When the test piece 5 enters the guide cylinder 4 through the test inlet 41, the test piece cannot achieve free fall due to the blockage of the limiting piece. At the start of the test, the starting piece is moved up or down away from the limiting hole, that is, the starting piece and the limiting piece are separated. The test piece acts on the limiting piece due to gravity, and the limiting piece is pushed out of the guide cylinder from the limiting hole. At this time, the test piece can achieve free fall and finally fall onto the sample through the test outlet.

[0046] Preferably, as Figure 4As shown, the limiting member 8 is provided with an inclined surface 81, and the test piece 5 abuts against the limiting member 8 through the inclined surface 81. Since the limiting member is no longer limited by the starting member, and the test piece acts on the inclined surface of the limiting member due to gravity, the limiting member gradually moves outwards, so that the limiting member is pushed out of the guide cylinder. The test piece is no longer blocked and can fall from the top of the guide cylinder to the bottom to impact the specimen.

[0047] Preferably, as Figure 1 , 3 shown, the starting assembly further includes a driving member 9, and the driving member 9 is respectively connected to a plurality of starting members 7. A plurality of starting members 7 are respectively connected to the driving member 9. At the start of the test, the driving member is pushed downwards, so that the driving member drives a plurality of starting members to move, so that a plurality of starting members are simultaneously separated from a plurality of limiting members, so that a plurality of test pieces simultaneously achieve free fall, and the detection of a plurality of specimens is completed in one test.

[0048] More preferably, the driving member 9 is provided with a handle (not shown in the figure), and the driving member is pushed through the handle, so as to drive a plurality of starting members to move. Its structure is simple and the cost is low.

[0049] Furthermore, as Figures 1-2 shown, the utility model further includes a horizontal adjustment mechanism, and the horizontal adjustment mechanism includes a plurality of adjusting members 10 provided at the bottom of the test body 1. Preferably, the number of the adjusting members 10 is three, and the adjusting members 10 are adjusting bolts. Rotate the adjusting member to adjust the distance between the bottom of the test body and the ground or the platform, so as to adjust the levelness of the bottom of the test body, ensure that the test piece impacts the specimen in a vertically free-falling state, and further ensure the accuracy of the test results.

[0050] Preferably, as Figure 2 shown, the horizontal adjustment mechanism further includes a spirit level 13 provided at the bottom of the test body 1. More preferably, the spirit level 13 is provided on the specimen placing platform 11. The setting of the spirit level can effectively test whether the bottom of the test body is in a horizontal state. The spirit level is a bubble level.

[0051] In summary, the utility model provides a protrusive road marker impact test device with simple structure, accurate test results and high test efficiency.

[0052] The above is the preferred embodiment of the utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the utility model.
