Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of road surface compaction degree detection, and in particular to an intelligent road surface compaction degree detection device. BACKGROUND

[0002] In highway pavement construction, compaction degree is a core index for measuring the strength and durability of asphalt mixture, and directly affects the service life of the pavement. Existing compaction degree detection technologies mainly include offline detection and online detection.

[0003] The online detection in engineering application has the following significant defects: first, existing compaction degree detection mostly uses external sensors or manual handheld devices, which need to be detected separately after the road roller stops working, resulting in disconnection between construction and detection processes, increased time consumption for single detection, and inability to provide real-time feedback on compaction quality. Some integrated devices use hydraulic drive detection arms, which have the problems of complex structure and high maintenance cost. Second, in asphalt pavement construction, the driving structure of the compaction degree detector is prone to attach pollutants such as asphalt residues and aggregate particles. Existing devices lack cleaning mechanisms associated with detection, resulting in large deviations in detection data. If the driving structure accumulates pollutants for a long time, it will hinder the detection process, further reducing construction efficiency. Finally, the detection module of some existing devices is often in a continuous power-on state, which maintains standby power consumption even when the road roller is running or not in the detection stage, resulting in shortened battery life and the need for frequent charging, which further affects continuous operation.

DETAILED DESCRIPTION

[0038] The application will be further described in detail in combination with the preferred embodiments and the accompanying drawings.

[0039] Referring to Figures 1 to 9 The application provides a technical solution: an intelligent road surface compaction detector, comprising a roller 1, one side of the roller 1 being fixedly connected with a roller 2, the intelligent road surface compaction detector further comprising cams 3, boosting links 6, gear sets 22, cleaning brushes 27, travel switch knobs 11 and compaction detectors 18 symmetrically arranged on both sides of the wheel part of the roller;

[0040] The roller 1 is fixedly installed with support mechanisms on both sides of the wheel part, so that the boosting links 6 drive the compaction detectors 18 to vertically reciprocate, and when the compaction detectors 18 are displaced downward to a road surface detection position, the compaction detectors 18 contact the asphalt mixture to collect compaction data through probes;

[0041] The rotating trigger mechanism is elastically installed in the interior of the support mechanism, and the wheel shaft of the roller is in transmission connection with the cam 3, so that the rotating motion of the cam 3 is converted into the linear reciprocating motion of the boosting link 6, and after the compaction detector 18 completes detection, the boosting link 6 is pulled upward to the initial position by the elastic reset member;

[0042] The cleaning mechanism, the cleaning linkage mechanism is in meshing connection with the boosting link 6 through the gear set 22, so that the vertical movement of the boosting link 6 drives the gear set 22 to rotate in opposite directions, and drives the cleaning brush 27 to rotate and wipe;

[0043] The switch trigger mechanism is fixedly installed in the interior of the support mechanism, so that when the boosting link 6 is returned upward to the initial position, the travel switch knob 11 is pressed, and the power supply of the probe of the compaction detector 18 is cut off.

[0044] The operation process of the overall detection device in the embodiment is as follows:

[0045] Road roller 1 operation stage: when the road roller 1 is running, the road roller wheel 2 is used to roll the road surface, and the two driving wheel shafts are connected by keys to drive the cam 3 to rotate at the same speed;

[0046] Cam 3 and top link 6 linkage: the eccentric structure of the outer surface of the cam 3 pushes the top link 6 to make vertical reciprocating motion along the guide direction of the support mechanism, so as to realize the lifting action of the compaction degree detector 18;

[0047] Detection trigger mechanism: when the top link 6 moves down to the lower dead point, the compaction degree detector 18 probe approaches the road surface, triggers the data acquisition module, and real-time acquires the density, modulus of resilience and other parameters of the asphalt mixture of the road surface, and completes the compaction degree detection of the road surface;

[0048] Elastic reset process: after the compaction degree detection is completed, the cam 3 rotates to the minimum radius section, and the release elastic potential energy of the rotation trigger mechanism is rotated to make the compaction degree detector 18 separate from the road surface, avoiding mechanical wear in the non-detection stage;

[0049] Cleaning linkage control: during the lifting process of the top link 6, the gear set 22 is also used to drive the cleaning brush 27 to rotate forward and backward, so as to spiral wipe the internal driving structure of the rotation trigger mechanism, so as to remove the attached asphalt residues, avoid scratching the internal driving structure or increase the sliding resistance of the detection;

[0050] Intelligent power-off logic: when the top link 6 moves up to the initial position, the travel switch button 11 is triggered, the probe power supply of the compaction degree detector 18 is cut off, the self-adaptive control of "power-on during detection and power-off during non-detection" is realized, and the endurance is improved to 8 hours of continuous operation.

[0051] It should be noted that the cam 3 rotates at the same speed as the driving wheel, so as to ensure that the detection frequency matches the rolling progress.

[0052] Referring to Figures 1 to 7 It is shown that in the present embodiment: the support mechanism comprises:

[0053] The support link 4 is fixedly installed on the driving wheel of the road roller 1 on both sides above the driving wheel, and the dustproof fixed cylinder 5 is fixedly connected to the lower end of the support link 4. The fixed frame 19 is fixedly installed on both sides of the middle end surface of the dustproof fixed cylinder 5.

[0054] In this embodiment: the support link 4 is fixedly connected to the driving wheel of the road roller 1 by high-strength bolts to form a portal support structure, which ensures the rigid connection of the detection device and the road roller body. The dustproof fixed cylinder 5 is formed by welding a steel plate and is integrally connected with the fixed frame 19 by welding, so that the load of the cleaning mechanism is evenly transmitted to the support link 4, and the meshing stability of the rotation trigger mechanism is ensured.

The top pushing connecting rod 6 moves along the axial line of the dustproof fixed cylinder 5 under the pushing of the cam 3, and drives the limiting top plate 7 to move downward synchronously, thereby pushing the detection driving arm 12 to extend out of the dustproof fixed cylinder 5. The limiting convex sleeve 13 is sleeved on the detection driving arm 12 through shaft shoulder positioning, and the spring 14 between the lower surface of the limiting convex sleeve 13 and the inner bottom wall of the dustproof fixed cylinder 5 forms an elastic buffering system to absorb the impact load generated by the road bumping. In the process of pushing the detection driving arm 12 by the top pushing connecting rod 6, the sliding block 16 of the limiting convex sleeve 13 stably slides in the first sliding groove 15 to guide the upward and downward displacement of the detection driving arm 12, realize the stable sliding of the detection driving arm 12, ensure the vertical contact precision of the probe and the road surface, and further improve the success rate of data acquisition.
