Description

Technical Field

[0001] The utility model relates to the technical field of road equipment detection, in particular to a device for measuring the impact resistance of raised road markers. Background Technique

[0002] Raised road markers, also known as road studs, are raised marking blocks fixed on the road surface for marking lines. They can be used on highways or other roads to mark the center line, lane dividing line, and edge line; they can also be used to mark dangerous sections such as curves, entrance and exit ramps, diversion markings, road narrowing, and road surface obstacles. Generally, they are used in conjunction with road surface markings or in the form of simulated road surface markings. After installation, the performance of raised road markers needs to be tested to meet the use standards. The test contents generally include appearance quality, structural dimensions, chromaticity performance, luminous intensity coefficient, compressive performance, overall impact resistance performance, and impact resistance performance of retroreflectors, etc.

[0003] The applicant discloses a device for measuring the impact resistance of raised road markers in a patent with the publication number CN217155786U, which is used for conducting a small ball drop impact experiment on the installed raised road markers, including a barrel body, bases arranged on both sides of the barrel body, and a release mechanism; among them, the release mechanism has a small ball, and the small ball is restricted by the release mechanism to stay on the surface of one port of the barrel body; the barrel body is a detachable structure and is composed of several sub-parts spliced together. By setting the barrel body, the release device, and the base as detachable structures, especially the barrel body being composed of several sub-parts, the volume can be reduced to more than half of the original volume when not in use, thus reducing the weight and volume of the external box during transportation, enabling more equipment to be loaded in a limited transportation space, or reducing the carrying weight when carried by manpower.

[0004] As can be seen from the above patent, the device for measuring the impact resistance of raised road markers sets the barrel body, the release device, and the base as detachable structures. Although it can reduce the weight and volume of the external box during transportation, load more equipment in a limited transportation space, or reduce the carrying weight when carried by manpower, in the actual use process, when the small ball drops and completes the impact on the raised road marker, it usually bounces up a certain distance and impacts the raised road marker again, thus reducing the accuracy of the detection result. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a device for measuring the impact resistance of raised road markers, aiming to solve the problem that when the existing device for measuring the impact resistance of raised road markers is in use, the sphere is prone to impact the raised road marker again, resulting in a reduction in the accuracy of the detection result.

[0006] To achieve the above object, the utility model provides an impact resistance measuring device for raised road markings, which includes a detachable barrel body. A release mechanism with a sphere is arranged at the top of the barrel body, and a base is arranged at the bottom of the barrel body. The barrel body is hollow inside. The device further includes a tray and a plurality of limiting blocks. The tray is coaxially arranged with the barrel body and is used for placing the raised road markings. A plurality of the limiting blocks are evenly and spacedly hinged along the circumference of the tray. Through holes are formed in the barrel wall of the barrel body corresponding to the positions of the plurality of limiting blocks. The plurality of limiting blocks are installed on the base in a limited and movable manner, and the plurality of limiting blocks can respectively pass through the plurality of through holes one by one to move towards or away from each other relative to the tray.

[0007] Preferably, a plurality of limiting grooves are formed in the base corresponding to the plurality of through holes one by one. Any one of the limiting blocks includes an installation part that is in sliding contact and cooperation with the limiting groove. One end of the installation part is hinged to the tray through a connecting rod. On both sides of the other end of the installation part, clamping blocks are respectively arranged through first elastic members. On both side walls of the limiting groove close to the bottom of the groove, clamping slots for the clamping blocks to extend into are formed. A second elastic member is arranged between the limiting block and the bottom of the limiting groove.

[0008] Preferably, the notch of the clamping slot and the end of the clamping block away from the installation part are respectively chamfered.

[0009] Preferably, any one of the limiting blocks further includes a limiting part for abutting against the sphere, and a handle is formed on the side of the limiting part away from the tray.

[0010] Preferably, a slope is formed on the side of the limiting part facing the tray, and the slope inclines downward and toward the direction close to the tray.

[0011] Preferably, a limiting groove for accommodating the raised road markings is formed on the top surface of the tray, and a flexible pad is arranged on the bottom surface of the tray.

[0012] Preferably, a bubble level is arranged on the base, and four support columns are arranged in a rectangular array. Any one of the support columns is detachably connected to the base, and one end of any one of the support columns is gradually expanded along its extending direction, and a rotating handle is arranged at the other end of any one of the support columns.

[0013] Beneficial effects:

[0014] 1. During the use of an impact resistance measuring device for raised road markers of the present utility model, after the release mechanism at the top of the barrel body releases the sphere, the sphere naturally falls inside the barrel body and impacts the raised road marker. After the sphere completes one impact on the raised road marker, it bounces upward. At this time, several limiting blocks can move towards each other relative to the tray, thereby clamping and limiting the sphere, or blocking and stopping the sphere above several limiting blocks, thus avoiding the sphere from making a secondary impact on the raised road marker, improving the accuracy of the detection result, and being reliable in use.

[0015] 2. During the use of an impact resistance measuring device for raised road markers of the present utility model, when it is necessary to place a raised road marker into the tray, by moving several limiting blocks towards each other relative to the tray, since the tray is hinged to several limiting blocks, at this time the tray can move downward and extend outside the base, so that the tester can place the raised road marker into the tray, which is convenient to use and simple to operate.

[0016] 3. During the use of an impact resistance measuring device for raised road markers of the present utility model, after the raised road marker is placed, by moving several limiting blocks away from each other relative to the tray, at this time the tray can move upward and retract into the base. Since the tray is coaxially arranged with the barrel body, the raised road marker placed on the tray is always directly below the sphere, thereby ensuring that the sphere can effectively impact the raised road marker and the impact position is relatively constant. The structural design is simple and reasonable. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Embodiment 1:

[0033] The present utility model provides an impact resistance measuring device for raised road markers.

[0034] In an embodiment of the present utility model, an impact resistance measuring device for raised road markers includes a detachable barrel body 1. A release mechanism 2 with a sphere is provided at the top of the barrel body 1. A base 3 is provided at the bottom of the barrel body 1. The barrel body 1 is hollow. It further includes a tray 4 and a plurality of limiting blocks 5. The tray 4 is coaxially arranged with the barrel body 1 and is used for placing the raised road marker. A plurality of limiting blocks 5 are evenly and spacedly hinged along the circumference of the tray 4. Through holes 6 are formed in the barrel wall of the barrel body 1 corresponding to the positions of the plurality of limiting blocks 5. The plurality of limiting blocks 5 are installed on the base 3 in a limiting and movable manner, and the plurality of limiting blocks 5 can respectively pass through the plurality of through holes 6 one by one to move towards or away from each other relative to the tray 4.

[0035] Specifically, as Figures 1 to 7 shown, in an impact resistance measuring device for raised road markers of the present utility model, since a release mechanism 2 with a sphere is provided at the top of the barrel body 1, a base 3 is provided at the bottom of the barrel body 1, and the barrel body 1 is hollow. When measuring the impact resistance of the raised road marker, the tester can install or release the sphere through the release mechanism 2, so that the sphere can fall naturally from the top of the barrel body 1 and impact the raised road marker. After the sphere impacts, the cracks on the raised road marker are observed and recorded, and at the same time, it is judged whether the impact resistance performance of the raised road marker is qualified, thereby completing the impact resistance measurement experiment of the raised road marker.

[0036] Furthermore, during the actual use of the impact resistance measuring device for raised road markers of the present utility model, since a plurality of limiting blocks 5 are evenly and spacedly hinged to the tray 4 along its circumferential direction, and through holes 6 are provided on the barrel wall of the barrel body 1 corresponding to the positions of the plurality of limiting blocks 5, and the plurality of limiting blocks 5 are installed on the base 3 in a limiting and movable manner. The limiting and movable manner of the plurality of limiting blocks 5 can be driven by an electric push rod, that is, the plurality of limiting blocks 5 are respectively detachably connected to the power output ends of the corresponding electric push rods. When it is necessary to place a raised road marker into the tray 4, the electric push rod drives the plurality of limiting blocks 5 to move towards each other relative to the tray 4. Since the tray 4 is hinged to the plurality of limiting blocks 5, at this time, the tray 4 can move downward and extend out of the base 3, so that the tester can place the raised road marker into the tray 4, which is convenient to use and simple to operate. After the raised road marker is placed, the tester operates the electric push rod to drive the plurality of limiting blocks 5 to move away from each other relative to the tray 4. At this time, the tray 4 can move upward and retract into the base 3. Since the tray 4 is coaxially arranged with the barrel body 1, it is ensured that the raised road marker placed on the tray 4 is always directly below the sphere, thereby ensuring that the sphere can effectively impact the raised road marker, and the impact position is relatively constant. The structural design is simple and reasonable.

[0037] It can be understood that after the release mechanism 2 at the top of the barrel body 1 releases the sphere, the sphere naturally falls in the barrel body 1 and impacts the raised road marker. After the sphere completes one impact on the raised road marker and bounces upward, at this time, the plurality of limiting blocks 5 can move towards each other relative to the tray 4 under the drive of the electric push rod, so as to clamp and limit the sphere, or block and stop the sphere above the plurality of limiting blocks 5, thereby avoiding the sphere from performing a secondary impact on the raised road marker, improving the accuracy of the detection result, and being reliable in use. It should be noted that if the limiting and movable manner of each limiting block 5 is driven by an electric push rod, a corresponding pressure sensor (or the start-stop button of the electric push rod) should be provided on the tray 4, and both the pressure sensor and the electric push rod are communicatively connected to the control module. After the sphere makes a downward impact on the raised road marker once, the pressure sensor is pressed and feeds back information to the control module, so that the control module controls the electric push rod to drive the limiting block 5 to move to limit the sphere. In addition, the electric push rod, the pressure sensor, the control module and their respective communication connection methods are all mature existing technologies and will not be elaborated here.

[0038] It should be noted that in a device for measuring the impact resistance of raised road markings according to the present utility model, the barrel body 1 and the release mechanism 2 are both mature prior arts. Specifically, the barrel body 1 and the release mechanism 2 in a device for measuring the impact resistance of raised road markings disclosed in the patent with the publication number CN217155786U by the applicant can be adopted. As a further technical improvement made by the applicant on this device for measuring the impact resistance of raised road markings, it is only aimed at solving the problem that when this device for measuring the impact resistance of raised road markings is in use, the sphere is likely to cause secondary impact on the raised road markings, resulting in a reduction in the accuracy of the detection results.

[0039] In an embodiment, a plurality of limiting grooves 7 are correspondingly formed in the base 3 in one-to-one correspondence with a plurality of through holes 6. Any limiting block 5 includes a mounting portion 8 that is in sliding contact and fit with the limiting groove 7. One end of the mounting portion 8 is hinged to the tray 4 through a connecting rod 9. On both sides of the other end of the mounting portion 8, clamping blocks 11 are respectively arranged through first elastic members 10. On both side walls of the limiting groove 7 close to the bottom of the groove, clamping slots 12 for the clamping blocks 11 to extend into are formed. A second elastic member 13 is arranged between the limiting block 5 and the bottom of the limiting groove 7.

[0040] As Figures 1 to 7 shown, it can be understood that when it is necessary to place a raised road marking into the tray 4, the tester slides the mounting portion 8 of the limiting block 5 in the direction close to the tray 4. Since one end of the mounting portion 8 is hinged to the tray 4 through a connecting rod 9, the tray 4 can be extended out of the base 3, which is convenient for the tester to place the raised road marking, with convenient operation and simple and reasonable structural design. At the same time, when the placement of the raised road marking is completed, the tester slides the mounting portion 8 of the limiting block 5 in the direction away from the tray 4. Since clamping blocks 11 are respectively arranged on both sides of the other end of the mounting portion 8 through first elastic members 10, and clamping slots 12 for the clamping blocks 11 to extend into are formed on both side walls of the limiting groove 7 close to the bottom of the groove, the limiting of the limiting block 5 can be realized through the clamping fit between the clamping blocks 11 and the clamping slots 12. At this time, the second elastic member 13 is in a compressed state. When the sphere falls and impacts the raised road marking, the raised road marking and the tray 4 are subjected to a downward force, which drives the first elastic member 10 to compress and makes the clamping blocks 11 disengage from the clamping slots 12. The limiting block 5 quickly moves towards the tray 4 under the elastic restoring force of the second elastic member 13, thereby realizing the clamping and limiting of the sphere or blocking the sphere above the limiting block 5 to prevent the sphere from causing secondary impact on the raised road marking and ensuring the accuracy of the detection results.

[0041] It should be noted that both the first elastic member 10 and the second elastic member 13 can be springs in the prior art. Springs have the characteristics of compact structure, large elastic deformation, and easy material selection, which facilitates the realization of the limit drive of the limit block 5. Compared with the limit movement mode of the electric push rod, using a spring to limit and drive the limit block 5 can save the manufacturing and production costs of the present invention, has good economy, and is more rapid and convenient for disassembly, installation, inspection and repair.

[0042] It should be noted that in a protrusion roadmark impact resistance measuring device provided in this embodiment, for the convenience of viewing and understanding, the attached Figures 1 to 7 is a schematic diagram of a protrusion roadmark impact resistance measuring device of the present invention. The drawing ratio of the shown components is different from the actual size. The relative size of each component in the protrusion roadmark impact resistance measuring device of the present invention is subject to the production drawing of the actual product.

[0043] In one embodiment, as Figures 4 to 7 shown, specifically, the notch of the slot 12 and the end of the block 11 away from the mounting portion 8 are respectively chamfered, so as to improve the smoothness of the clamping fit or disengagement fit between the block 11 and the slot 12, enabling the limit block 5 to quickly limit the sphere.

[0044] In one embodiment, any limit block 5 further includes a limiting portion 14 for abutting against the sphere, and a handle 15 is formed on the side of the limiting portion 14 away from the tray 4. Specifically, as Figures 1 to 7 shown, by abutting the limiting portion 14 against the sphere, the contact area between the limit block 5 and the sphere can be increased, thereby improving the clamping stability of the sphere and ensuring reliable use. Further, through the handle 15, it is convenient for the tester to pull the limit block 5 away from the tray 4 and make the block 11 and the slot 12 in clamping fit to limit the limit block 5, which is convenient for operation.

[0045] In one embodiment, as Figures 1 to 5 shown, a slope 16 is formed on the side of the limiting portion 14 facing the tray 4, and the slope 16 inclines downward towards the direction close to the tray 4. It can be understood that when the sphere bounces above the limit block 5, at this time, the slopes 16 on several limiting portions 14 can enclose an inverted conical groove for accommodating the sphere, so as to circumferentially limit the sphere and prevent the sphere from rolling randomly in the barrel body 1 and affecting the detection.

[0046] In one embodiment, a limiting groove 17 for accommodating the protrusion roadmark is formed on the top surface of the tray 4, and a flexible pad 18 is provided on the bottom surface of the tray 4. Specifically, as Figure 2 and Figure 4As shown, the limiting groove 17 can prevent the raised road sign from popping out of the tray 4 due to its own rebound after being impacted by the falling sphere, ensuring the stable placement of the raised road sign. Further, since a flexible pad 18 is provided on the bottom surface of the tray 4, the flexible pad 18 can be a rubber pad in the prior art, thereby buffering the tray 4 and preventing the tray 4 from being knocked or damaged due to excessive impact force.

[0047] In one embodiment, a bubble level is provided on the base 3 and four support columns 19 are arranged in a rectangular array. Any one of the support columns 19 is detachably connected to the base 3, and one end of any one of the support columns 19 is tapered along its extending direction, and a rotating handle 20 is provided at the other end of any one of the support columns 19. Specifically, as Figure 1 shown, the base 3 can be stably supported by the four support columns 19 arranged in a rectangular array, ensuring the stable placement of the present utility model. Further, any one of the support columns 19 is detachably connected to the base 3. The detachable connection manner between any one of the support columns 19 and the base 3 can be a threaded connection, so that a single support column 19 can be rotated and adjusted and used in cooperation with the bubble level provided on the base 3, so that the base 3 is always in a relatively horizontal position state, that is, the barrel body 1 and the base 3 are always in a perpendicular position state, effectively avoiding the contact between the sphere and the inner wall of the barrel body 1 during the falling process and affecting the test results, and the use is reliable.

[0048] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
