Description

Technical Field

[0001] This utility model relates to the field of construction measurement technology, specifically to an asphalt paving thickness detection device. Background Technology

[0002] Existing high-grade highways generally use asphalt as the surface paving material, and the thickness of the surface asphalt layer is one of the important indicators for detecting the quality of the highway pavement. Generally, a testing device is inserted into the asphalt to test it after the pavement asphalt layer has just been laid and before it has fully hardened.

[0003] Most existing devices for detecting asphalt paving thickness consist of measuring rulers and measuring rods. The thickness of the asphalt paving is roughly judged by directly observing the length of the measuring rod inserted into the asphalt. However, the accuracy of this detection method is greatly affected by the subjective judgment of the measuring personnel and the degree of tilt when the measuring rod is inserted, resulting in low accuracy. Moreover, the measuring personnel can often only stand next to the road surface to measure the edge of the asphalt pavement, making it difficult to measure the middle area of ​​the asphalt pavement, thus leading to an incomplete detection. Utility Model Content

[0004] The purpose of this invention is to provide an asphalt paving thickness detection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A device for detecting the thickness of asphalt paving includes a connecting seat, a measuring cylinder installed at the bottom of the connecting seat, a laser rangefinder sensor installed at the bottom of the measuring cylinder, grooves on both sides of the measuring cylinder, a measuring plate inside the measuring cylinder, connecting parts on both sides of the measuring plate, the connecting parts passing through the grooves and fixedly connected to a slip ring located outside the measuring cylinder, guide rod sleeves installed on both sides of the measuring cylinder, guide rods inside the guide rod sleeves, the top end of the guide rods fixedly connected to the slip rings, a support plate installed at the bottom end of the guide rods, a rod body fixed to one side of the connecting seat, a rod sleeve slidably fitted around the rod body, threaded fixing assemblies on both the rod sleeve and the connecting seat, the rod sleeve being relatively fixed to the rod body via the threaded fixing assemblies, the connecting seat being relatively fixed to the rod body via the threaded fixing assemblies, a level tube installed on the upper part of the rod sleeve, and a display installed on one side of the rod sleeve, the display being electrically connected to the laser rangefinder sensor.

[0007] As a further embodiment of this utility model, a handle is installed on the rod.

[0008] As a further improvement of this utility model, a pull ring is installed on the top of the connecting seat.

[0009] As a further improvement of this utility model, the bottom surface of the measuring cylinder is a detachable bottom surface.

[0010] As a further improvement of this utility model, the distance between the laser rangefinder and the measuring plate is equal to the length of the measuring rod located below the support plate.

[0011] As a further improvement of this utility model, the support plate has a through hole in the middle to facilitate the passage of the measuring rod.

[0012] As a further embodiment of this utility model: the threaded fixing assembly includes a threaded rod and a nut, and the rod body is provided with a plurality of adjustment holes at equal intervals that are adapted to the threaded rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the coordinated arrangement of a measuring cylinder, slip ring, connecting part, measuring plate, laser distance sensor, guide rod sleeve, guide rod, support plate, measuring rod, slide groove, and display, can convert the depth of the measuring rod inserted into the asphalt into the distance measured by the laser distance sensor. In this way, the asphalt paving thickness can be indirectly measured by laser distance measurement, which is more efficient, convenient, and accurate compared with the existing method of measuring distance by directly observing the measuring ruler or measuring rod with the naked eye.

[0015] 2. This utility model, by setting an adjustable extension rod composed of a rod cylinder and a rod body, allows personnel to conveniently stand on one side of the asphalt pavement to detect the paving thickness of the asphalt pavement. This enables the measuring personnel to only stand next to the asphalt pavement to detect the thickness in the middle of the asphalt pavement, thus making the detection range larger.

[0016] 3. The rod body and connecting seat of this utility model adopt a detachable installation method, which can easily separate the rod body and rod cylinder from the connecting seat. This allows personnel to easily carry the rod body by pulling the ring and refer to the thickness scale line on the outer wall of the measuring cylinder for thickness detection, providing users with different options and meeting diverse usage needs.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 In this embodiment of the utility model, an asphalt paving thickness detection device includes a connecting seat 1, a measuring cylinder 2 installed at the bottom of the connecting seat 1, a laser rangefinder sensor 6 installed at the bottom of the measuring cylinder 2, sliding grooves 11 on both sides of the measuring cylinder 2, a measuring plate 5 inside the measuring cylinder 2, connecting parts 4 on both sides of the measuring plate 5, the connecting parts 4 passing through the sliding grooves 11 and fixedly connected to a slip ring 3 located outside the measuring cylinder 2, guide rod sleeves 7 installed on both sides of the measuring cylinder 2, guide rods 8 inside the guide rod sleeves 7, the top end of the guide rods 8 fixedly connected to the slip ring 3, and a support plate 9 installed at the bottom end of the guide rods 8.

[0023] The bottom surface of the measuring cylinder 2 is detachable. The detachable bottom surface is connected to the cylinder body of the measuring cylinder 2 by screws. This makes it convenient for personnel to disassemble the laser range sensor 6 inside the measuring cylinder 2, so as to facilitate the disassembly, replacement or maintenance of the laser range sensor 6.

[0024] The distance between the laser rangefinder 6 and the measuring plate 5 is equal to the length of the measuring rod 10 below the support plate 9. This design allows the laser rangefinder 6 to detect the depth of the measuring rod 10 inserted into the asphalt in real time.

[0025] Thickness scale lines 12 are provided on the outer wall of the measuring cylinder 2. The thickness scale lines 12 can facilitate personnel to observe and detect the thickness of asphalt paving without using an extension rod.

[0026] The support plate 9 has a through hole in the middle to facilitate the passage of the measuring rod 10, so that the measuring rod 10 can easily pass through the support plate 9 and be inserted into the asphalt.

[0027] Please see Figure 1A rod body 14 is fixed to one side of the connecting seat 1. A rod cylinder 13 is slidably sleeved on the outside of the rod body 14. Both the rod cylinder 13 and the connecting seat 1 are provided with threaded fixing components 16. The rod cylinder 13 is fixed to the rod body 14 through the threaded fixing components 16. The connecting seat 1 is fixed to the rod body 14 through the threaded fixing components 16. A level tube 17 is installed on the upper part of the rod cylinder 13. The setting of the level tube 17 allows personnel to easily observe whether the rod cylinder 13 and the rod body 14 are horizontal. When the rod cylinder 13 and the rod body 14 are horizontal, the measuring rod 10 will also remain vertical and inserted into the asphalt, thereby making the test results more accurate. A display 18 is installed on one side of the rod cylinder 13. The display 18 is electrically connected to the laser range sensor 6. The laser range sensor 6 and the display 18 are connected to an external power supply.

[0028] A handle 19 is installed on the rod cylinder 13. The handle 19 makes it easy for personnel to lift the device, improving the ease of use of the device.

[0029] A pull ring 20 is installed on the top of the connecting seat 1. The pull ring 20 allows personnel to carry the measuring device directly for measurement when the extension rod is not needed.

[0030] The threaded fixing assembly 16 includes a threaded rod and a nut. The rod body 14 has several adjustment holes 15 that are adapted to the threaded rod at equal intervals. The adjustment holes 15 can be set to facilitate the adjustment of the extension length of the rod body 14.

[0031] The working principle of this utility model is as follows: During testing, personnel stand beside the newly paved asphalt pavement and lift the measuring structure at the front of the rod body 14 by holding the rod cylinder 13 with the handle 19. Then, they slowly place the device flat on the asphalt pavement and continue to press the measuring cylinder 2 downwards through the rod cylinder 13 and the rod body 14. The measuring cylinder 2 will then drive the measuring rod 10 to slowly insert into the asphalt until it contacts the harder cement-stabilized crushed stone layer at the bottom. During this process, the measuring rod 10 will move downwards relative to the support plate 9, and at the same time, the distance between the laser distance sensor 6 and the measuring plate 5 inside the measuring cylinder 2 will continuously increase. The distance measured by the laser distance sensor 6 to the measuring plate 5 is the depth of the measuring rod 10 inserted into the asphalt. Personnel only need to observe the real-time distance measurement data on the display 18 to obtain the real-time insertion depth, and thus directly obtain the asphalt paving thickness. After a single measurement, the measuring personnel can adjust the length of the rod body 14 extending out of the rod cylinder 13 to measure the paving thickness at different locations on the asphalt pavement.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
