Description

Technical Field

[0001] This utility model belongs to the field of auxiliary components for asphalt compaction testing, and specifically relates to a device for testing the compaction of colored asphalt concrete pavement. Background Technology

[0002] Asphalt concrete pavement rollers have achieved information-based construction, equipped with compaction degree testing systems, evenness testing systems, permeability testing systems, width and elevation testing systems, and friction coefficient testing systems, enabling quality monitoring during construction. Specifically, when selecting a compaction degree testing system for a roller, common methods for evaluating asphalt pavement compaction include nucleus-free (nuclear) density metering and core sampling. While these methods can reflect pavement quality to some extent, they all have limitations, such as limited coverage and significant destructiveness, making it difficult to comprehensively and objectively evaluate the overall pavement construction quality. The emergence of ground-penetrating radar (GPR) technology provides a practical solution to this need. With its non-destructive and continuous testing characteristics, it has become an ideal choice, effectively meeting the requirements for pavement quality inspection. Therefore, in existing technologies, it is common practice to install GPR instruments on rollers to test the compaction degree of asphalt pavements.

[0003] In recent years, colored asphalt has been increasingly used on small roads or squares to beautify the environment and create a comfortable environment. In particular, running tracks in squares or residential areas are used for citizens or residents to run and exercise, and have high requirements for flatness and compaction to improve comfort and safety.

[0004] Specifically, in the installation process of ground penetrating radar (GPR) on road rollers, angle steel brackets are usually first installed on the side of the road roller body, and then the GPR is usually installed on the angle steel brackets with screws. This makes it very inconvenient to disassemble and reassemble the GPR after installation, which is not convenient for subsequent removal of the GPR for inspection and maintenance. At the same time, once the installation is completed, the position and height of the GPR are usually fixed, making it impossible to adjust the operating height of the GPR probe. Utility Model Content

[0005] The purpose of this invention is to provide a device for testing the compaction degree of colored asphalt concrete pavement in order to solve the above-mentioned problems, as detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This utility model provides a colored asphalt concrete pavement compaction degree testing device, including an angle steel support and a ground penetrating radar instrument body. The angle steel support is vertically arranged, and the side of the angle steel support is fixedly connected to the side of the roller body. The front of the angle steel support is equipped with a height adjustment component with vertical sliding adjustment and locking functions.

[0008] A mounting plate is fixedly installed on the front of the height adjustment component. Several disassembly and assembly components are assembled on the front of the mounting plate. The ground penetrating radar instrument body is detachably fixed to the front of the mounting plate through the disassembly and assembly components. This allows the height adjustment function of the ground penetrating radar instrument body to be realized by means of the height adjustment component, and at the same time, it allows the quick disassembly and assembly function of the ground penetrating radar instrument body to be realized by means of the disassembly and assembly components.

[0009] Preferably, the ground penetrating radar instrument body is a Pavescan RDM 2.0 ground penetrating radar compaction measuring instrument, and the probe of the ground penetrating radar instrument body is located on the bottom surface and suspended below the angle steel support.

[0010] Preferably, the side of the angle steel support is provided with multiple connecting holes for inserting and installing screws.

[0011] Preferably, the height adjustment assembly includes a guide groove and a fixing plate. The guide groove is vertically opened at the front of the angle steel support, and the guide groove is a through groove in the longitudinal direction. Several guide studs are inserted into the guide groove in a sliding fit in the longitudinal direction. The front ends of the guide studs extending out of the guide support are all vertically fixed to the rear end face of the fixing plate. The outer periphery of the rear end of the guide studs extending out of the guide support is coaxially engaged with a clamping nut.

[0012] Preferably, the guide grooves are all vertically arranged waist-shaped long grooves, and the periphery of the clamping nut does not interfere with the side of the angle steel support.

[0013] Preferably, the guide studs are all fitted with anti-loosening washers in the gaps between the fixing plate and the clamping nut and the angle steel support, and the rear ends of the guide studs are all coaxially mounted with end heads.

[0014] Preferably, each of the disassembly and assembly components includes a connecting plate and a mating groove. Several connecting plates are installed on the back of the ground penetrating radar instrument body, and each connecting plate has a mating seat fixed longitudinally on its back. Each mating seat has a limiting hole opened laterally on one side end face, and the limiting holes are all through holes. Several fixing sleeves are fixed longitudinally on the front of the fixing plate, and each fixing sleeve has a mating groove opened longitudinally on its front. Each mating seat corresponds to a mating groove and slides vertically. Each fixing sleeve has a mounting hole opened laterally on one side, and each mounting hole is perpendicularly connected to the corresponding mating groove. Each mounting hole is laterally coaxially aligned with the limiting hole. Each mounting hole has a limiting rod inserted coaxially through it in a sliding fit, and the inner end of each limiting rod slides laterally with the corresponding limiting hole.

[0015] Preferably, the outer ends of the limiting rods extend out of the corresponding outer side of the fixing sleeve and are coaxially fixed with handles. The portion of the limiting rod located between the corresponding handle and the outer side of the fixing sleeve is coaxially fitted with a spring, and the two ends of the spring are respectively fixedly connected to the corresponding handle and the outer side of the fixing sleeve.

[0016] Preferably, the cross-sectional shape of both the mating seat and the mating groove along the horizontal and vertical planes is rectangular.

[0017] Preferably, the mating grooves are all blind grooves in the longitudinal direction, and the rear end face of the mating seat is in close contact with the rear end face of the corresponding mating groove.

[0018] The aforementioned colored asphalt concrete pavement compaction testing device, specifically, involves the ground-penetrating radar (GPR) instrument body being used in conjunction with a road roller. The side of the angle steel support is fixedly connected to the road roller body, while the front of the angle steel support is equipped with a height adjustment component. The mounting plate at the front of the height adjustment component is assembled with the GPR instrument body via a disassembly and assembly assembly. By using the guide stud of the height adjustment component to slide vertically along the guide groove and tightening the clamping nut, the vertical position of the GPR instrument body can be adjusted. This allows for adaptive adjustment of the probe's height based on actual road conditions, improving the flexibility and road applicability of the GPR instrument body. Furthermore, due to the... The longitudinal sliding engagement between the mating seat and the mating groove, and the transverse sliding engagement between the limiting rod and the limiting hole of the assembly assembly, allow the ground penetrating radar body to be detachably assembled at the front of the mounting plate. This assembly method is simple and easy to implement, facilitating quick assembly and installation. Furthermore, since the mating seat can slide longitudinally out of the mating groove simply by pulling the limiting rod out of the limiting hole, the ground penetrating radar body can be detached from the front of the mounting plate. This detachment method is also simple and easy to implement, facilitating subsequent maintenance, repair, and proper storage after the ground penetrating radar body is removed from the front of the mounting plate.

[0019] The beneficial effects are as follows: 1. This utility model fixes the side of the angle steel support to the body of the road roller. At the same time, the front of the angle steel support is equipped with a height adjustment component. The mounting plate at the front of the height adjustment component is assembled with the ground penetrating radar body through the assembly and disassembly assembly. Then, by means of the guide stud of the height adjustment component, the vertical position height of the ground penetrating radar body can be adjusted by sliding vertically along the guide groove and tightening the clamping nut. This makes it easy to adapt the height of the probe to the actual road conditions, thereby improving the flexibility of the ground penetrating radar body and its applicability to the road surface.

[0020] 2. By using the longitudinal sliding fit between the mating seat and the mating groove of the assembly components and the lateral sliding fit between the limiting rod and the limiting hole, the ground penetrating radar body can be detachably assembled at the front of the mounting plate. The assembly method of the ground penetrating radar body at the front of the mounting plate is simple and easy to achieve, which facilitates the quick assembly of the ground penetrating radar body at the front of the mounting plate for installation and use.

[0021] 3. Simply pull the limiting rod out of the limiting hole to allow the mating seat to slide forward longitudinally out of the mating groove. This allows the ground penetrating radar instrument body to be removed from the front of the mounting plate. The method of removing the ground penetrating radar instrument body from the front of the mounting plate is simple and easy to achieve, which facilitates subsequent maintenance, repair, and proper storage of the ground penetrating radar instrument body after it is removed from the front of the mounting plate.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] See Figures 1-7 As shown, this utility model provides a colored asphalt concrete pavement compaction testing device, including an angle steel support 2 and a ground-penetrating radar instrument body 1. The angle steel support 2 is vertically arranged, and its side is fixed to the side of the roller body. The front of the angle steel support 2 is equipped with a height adjustment component 3 with vertical sliding adjustment and locking functions. Specifically, the height adjustment component 3 includes a guide groove 301 and a fixing plate. The guide groove 301 is vertically opened at the front of the angle steel support 2, and the guide groove 301 is a through groove in the longitudinal direction. The guide groove 301 slides through the longitudinal direction. Several guide studs 304 are inserted, and the front ends of the guide studs 304 extending out of the guide support are all vertically fixed to the rear end face of the fixing plate. The outer periphery of the rear end of the guide studs 304 extending out of the guide support is coaxially engaged with a clamping nut 302. The purpose of this arrangement is that, by means of the guide studs 304 of the height adjustment component 3 sliding vertically along the guide groove 301 and tightening the clamping nut 302, the vertical position height of the ground penetrating radar body 1 can be adjusted, thereby facilitating the adaptive adjustment of the operating position height of the probe 101 according to the actual road conditions.

[0034] See Figures 1-4As shown, a mounting plate 4 is fixedly installed on the front of the height adjustment component 3. Several disassembly and assembly components 5 are assembled on the front of the mounting plate 4. The ground-penetrating radar instrument body 1 is detachably fixed to the front of the mounting plate 4 via the disassembly and assembly components 5. This allows for height adjustment of the ground-penetrating radar instrument body 1 using the height adjustment component 3, and also enables quick disassembly and assembly of the ground-penetrating radar instrument body 1 using the disassembly and assembly components 5. Specifically, each disassembly and assembly component 5 includes a connecting plate 504 and a mating groove 505. A mounting plate 504 is installed on the back of the ground-penetrating radar instrument body 1. Several connecting plates 504 are provided, and each connecting plate 504 has a mating seat 506 fixed longitudinally on its back side. Each mating seat 506 has a limiting hole 507 opened laterally on one side end face, and the limiting holes 507 are all through holes. Several fixing sleeves 501 are fixed longitudinally on the front side of the fixing plate. Each fixing sleeve 501 has a mating groove 505 opened longitudinally on its front side, and the mating seat 506 corresponds to the mating groove 505 one by one and slides vertically. Each fixing sleeve 501 has a mounting hole 508 opened laterally on one side, and the mounting hole 508 is perpendicularly connected to the corresponding mating groove 505. Furthermore, the mounting holes 508 are laterally coaxially aligned with the limiting holes 507. Each mounting hole 508 has a sliding fit with a limiting rod 509, and the inner end of each limiting rod 509 is laterally slidingly fitted with the corresponding limiting hole 507. The outer end of each limiting rod 509 extends beyond the outer side of the corresponding fixing sleeve 501 and is coaxially fixed with a handle 503. A spring 502 is coaxially fitted with the portion of the limiting rod 509 between the corresponding handle 503 and the outer side of the fixing sleeve 501, and both ends of the spring 502 are respectively fixed to the outer side of the corresponding handle 503 and the outer side of the fixing sleeve 501. The fixed connection is designed so that the ground-penetrating radar body 1 can be detachably assembled to the front of the mounting plate 4 by longitudinally sliding the mating seat 506 and the mating groove 505 and laterally sliding the limiting rod 509 and the limiting hole 507 of the assembly 5. At the same time, by simply pulling the limiting rod 509 out of the limiting hole 507, the mating seat 506 can slide forward longitudinally out of the mating groove 505, thereby detaching the ground-penetrating radar body 1 from the front of the mounting plate 4. The assembly and disassembly of the ground-penetrating radar body 1 at the front of the mounting plate 4 is simple and easy to implement.

[0035] See Figures 1-7As shown, the following optimizations have been made to this application. Specifically, the ground-penetrating radar (GPR) instrument body 1 is a Pavescan RDM 2.0 GPR compaction measuring instrument, and the probe 101 of the GPR instrument body 1 is located on the bottom surface and suspended below the angle steel support 2. This setting facilitates the procurement and acquisition of the GPR instrument body 1. Furthermore, the GPR instrument body 1 provides a simple and economical evaluation tool to determine the dielectric value of asphalt pavement during its service life using a non-destructive testing method. Moreover, it is a dielectric profile system, making it the preferred testing method for identifying uneven areas in new asphalt pavement. It can collect data through two different testing methods: dielectric value or porosity. There are no on-site hazards, and the working area does not need to be closed as with nuclear instruments / radioactive products. Optionally, the side of the angle steel support 2 is provided with multiple connecting holes 201 for inserting and installing screws, so that the angle steel support 2 can be fixed to the side of the road roller body by inserting screws through the connecting holes 201. Of course, the angle steel support 2 can also be directly welded to the side of the road roller body.

[0036] See Figures 1-7 As shown, the guide grooves 301 are all vertically arranged waist-shaped elongated grooves. The outer periphery of the clamping nut 302 does not interfere with the side of the angle steel support 2, so that the guide grooves 301 have a wide adjustment range in the vertical direction, and at the same time, it is easy to tighten and loosen the clamping nut 302 smoothly. Further optionally, the guide studs 304 are coaxially fitted with anti-loosening washers 305 in the gaps between the fixing plate and the clamping nut 302 and the angle steel support 2. The rear end of the guide studs 304 is coaxially mounted with an end head 303, so as to enhance the stability of the clamping nut 302 after tightening with the help of the anti-loosening washer 305, and at the same time, it is easy to prevent the clamping nut 302 from accidentally coming off with the help of the end head 303. Furthermore, both the mating seat 506 and the mating groove 505 have rectangular cross-sectional shapes along their horizontal and vertical planes. The mating groove 505 is a blind groove in the longitudinal direction, and the rear end face of the mating seat 506 is in close contact with the rear end face of the corresponding mating groove 505. This design facilitates good guidance when the mating seat 506 slides longitudinally along the mating groove 505. At the same time, during the longitudinal sliding process of the mating seat 506 along the mating groove 505, when the mating seat 506 drives the limiting hole 507 to slide longitudinally to be aligned with the limiting rod 509 laterally, the contact between the rear end face of the mating seat 506 and the rear end face of the corresponding mating groove 505 provides a clear indication.

[0037] With the above structure, specifically when the ground-penetrating radar instrument body 1 is used in conjunction with a road roller, the side of the angle steel support 2 is fixedly connected to the road roller body. Simultaneously, a height adjustment component 3 is assembled at the front of the angle steel support 2. The mounting plate 4 at the front of the height adjustment component 3 is assembled with the ground-penetrating radar instrument body 1 via a disassembly and assembly assembly 5. Then, by using the guide stud 304 of the height adjustment component 3 to slide vertically along the guide groove 301 and tightening the clamping nut 302, the vertical position height of the ground-penetrating radar instrument body 1 can be adjusted. This facilitates adaptive adjustment of the probe 101's operating position height according to actual road conditions, improving the flexibility and road applicability of the ground-penetrating radar instrument body 1. Furthermore, due to the mating seat of the disassembly and assembly assembly 5... The longitudinal sliding engagement of the ground penetrating radar instrument body 1 with the mating groove 505 and the transverse sliding engagement of the limiting rod 509 with the limiting hole 507 allows the ground penetrating radar instrument body 1 to be detachably assembled at the front of the mounting plate 4. The assembly method of the ground penetrating radar instrument body 1 at the front of the mounting plate 4 is simple and easy to implement, which facilitates the quick assembly of the ground penetrating radar instrument body 1 at the front of the mounting plate 4 for installation and use. At the same time, since only the limiting rod 509 needs to be pulled out of the limiting hole 507 to allow the mating seat 506 to slide forward longitudinally out of the mating groove 505, the ground penetrating radar instrument body 1 can be removed from the front of the mounting plate 4. The disassembly method of the ground penetrating radar instrument body 1 at the front of the mounting plate 4 is simple and easy to implement, which facilitates the subsequent maintenance, repair, and proper storage of the ground penetrating radar instrument body 1 after it is removed from the front of the mounting plate 4.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
