Description

Technical Field

[0001] The utility model relates to the technical field of road structure layer thickness detection, in particular to an insertion type thickness detection device. Background Technique

[0002] At present, during the construction of the road structure layer, special personnel are usually arranged to track and detect the paving thickness. The traditional method is as follows: a screwdriver is used in cooperation with a steel ruler to measure the loose paving thickness of asphalt concrete paving. By comparing with the controlled loose paving thickness value, and then, the loose paving thickness is adjusted according to the difference value. During the implementation of the traditional detection method, the influence of human factors is relatively large. When measuring the loose paving thickness, the screwdriver is often inserted into the top surface of the lower bearing layer, and then the top of the loose paving surface layer is held by fingers and the screwdriver is pinched, and then the screwdriver is pulled out. The loose paving thickness is measured by a steel ruler. When measuring the thickness by the traditional method, when the viewing angles of the measuring staff are different, the top surface of the loose paving surface layer observed will be slightly different, which will lead to measurement thickness errors, easily resulting in uneven thickness of the asphalt concrete surface layer, cost waste, unqualified construction quality or even rework; in addition, in order to make the measured actual paving thickness data more accurate and find the top surface of the loose paving surface layer as accurately as possible, the measuring staff often takes a long time to measure, which affects the work efficiency. In addition, the traditional method is not safe enough, and it is easy to cause finger burns due to the high temperature of asphalt during the process of measuring the thickness. Content of the Utility Model

[0003] Therefore, the technical problem to be solved by the utility model is to overcome the defects in the prior art, so as to provide an insertion type thickness detection device.

[0004] An insertion type thickness detection device includes: a measuring rod, a measuring limit plate and a scale ruler. The scale ruler is slidably arranged on the measuring rod. A measuring limit plate is connected to one side of the scale ruler close to the detection working end of the measuring rod. A plurality of elastic locking blocks are arranged between the measuring limit plate and the measuring rod. A handle is arranged at one end of the measuring rod far from the detection working end. The device further includes a locking cable. One end of the locking cable is connected to the handle, and the other end of the locking cable is connected to the elastic locking block.

[0005] Further, the plurality of elastic locking blocks are evenly distributed along the circumferential direction of the measuring rod.

[0006] Further, an electronic digital display scale is further arranged on the scale ruler.

[0007] Further, the measuring rod is provided with scales.

[0008] Further, the detection working end of the measuring rod is conical.

[0009] Further, the measuring limit plate is perpendicular to the scale ruler.

[0010] Further, the cross-section of the measuring rod is circular, and the diameter of the measuring rod is 20 mm.

[0011] Further, the handle is connected to the measuring rod by welding, the measuring limit plate is connected to the scale ruler by welding, and the measuring limit plate is made of alloy steel.

[0012] Further, the scale on the scale ruler is 0 - 500 mm, and the length of the measuring rod is 1000 mm.

[0013] Further, the length of the measuring limit plate is 100 mm, the width of the measuring limit plate is 30 mm, and the thickness of the measuring limit plate is 5 mm.

[0014] The technical solution of the present utility model has the following advantages:

[0015] 1. An insertion type thickness detection device provided by the present utility model can accurately position the top surface of the road structure layer through the measuring limit plate. At the same time, a scale ruler is slidably arranged on the measuring rod. When the detection working end of the measuring rod is inserted into the subbase layer of the road structure layer, the measuring limit plate drives the scale ruler to move together, and then the depth data of the detection working end inserted into the subbase layer of the road structure layer can be measured. The handle can not only increase the portability of the detection device, but also when measuring the depth, squeezing or loosening the handle can adjust the tightness of the locking cable, thereby controlling the opening and closing of the elastic locking block, which is convenient for fixing the position of the measuring limit plate after the measurement to read the size, and also improves the safety of the detection device during the measurement process, avoiding damage to the measurement personnel.

[0016] 2. In the technical solution provided by the present utility model, by evenly distributing the elastic locking blocks along the circumferential direction of the measuring rod, stress concentration can be reduced, and the stability of the elastic locking blocks when locking can be increased. On the basis that the detection device already has a scale ruler for size measurement, an electronic digital display ruler is added, which can improve the convenience of size data measurement and work efficiency. The detection working end of the measuring rod is conical, which can make the measuring rod more conveniently inserted into the subbase layer of the road structure layer. The measuring limit plate and the scale ruler are perpendicular to each other, which can make the measuring limit plate fit the top surface of the road structure layer, so that the measured data is more accurate.

[0025] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] Such as Figures 1 to 2An insertion - type thickness detection device shown in the figure includes: a measuring rod 2, a measuring limit plate 4, and a scale ruler 5. The scale ruler 5 is slidably arranged on the measuring rod 2. A measuring limit plate 4 is connected to one side of the scale ruler 5 close to the detection working end of the measuring rod 2. A plurality of elastic locking blocks 6 are arranged between the measuring limit plate 4 and the measuring rod 2. A handle 1 is arranged at one end of the measuring rod 2 far from the detection working end. The device also includes a locking cable. One end of the locking cable is connected to the handle 1, and the other end of the locking cable is connected to the elastic locking blocks 6. An installation through - hole is provided at the central position of the measuring limit plate 4. The non - working ends of the plurality of elastic locking blocks 6 are fixedly connected in the installation through - hole on the measuring limit plate 4. The elastic locking blocks 6 are in a locked and closed mode under normal conditions, that is, when the handle 1 is released, the locking cable is released, and the working ends of the plurality of elastic locking blocks 6 are closely attached to the measuring rod 2, so that the position of the measuring limit plate 4 is fixed, facilitating the reading of the measured data. When the handle 1 is pinched, the locking cable is tightened, and the working ends of the plurality of elastic locking blocks 6 gradually expand and move outwards from the measuring rod 2, separating the elastic locking blocks 6 from the measuring rod 2. At this time, the measuring limit plate 4 can move for depth measurement. In addition, it should be noted that the measuring limit plate 4 is connected to the scale ruler 5. Therefore, when the elastic locking blocks 6 are separated from the measuring rod 2, the moving trajectory of the measuring limit plate 4 will not be changed, that is, the measuring limit plate 4 will not be affected, and the measured data will not be affected. Considering that the measuring personnel usually need to adjust the detection device to a horizontal position during the reading process, it is set that when the handle 1 is released, the working ends of the plurality of elastic locking blocks 6 are closely attached to the measuring rod 2, so that the position of the measuring limit plate 4 is fixed, avoiding the need for the measuring personnel to keep pinching the handle 1 during the reading process and reducing the use burden of the measuring personnel.

[0027] For the above - mentioned insertion - type thickness detection device, the top surface of the road structure layer can be accurately positioned through the measuring limit plate 4. At the same time, the scale ruler 5 is slidably arranged on the measuring rod 2. When the detection working end of the measuring rod 2 is inserted into the sub - base layer of the road structure layer, the measuring limit plate 4 drives the scale ruler 5 to move together to measure the depth data of the detection working end inserted into the sub - base layer of the road structure layer. The handle 1 can not only increase the portability of the detection device, but also, when performing depth measurement, pinching or releasing the handle 1 can adjust the tightness of the locking cable to control the opening and closing of the elastic locking blocks 6, facilitating the fixing of the position of the measuring limit plate 4 for size reading after the measurement, and at the same time improving the safety of the measurement process of the detection device and avoiding damage to the measuring personnel.

[0028] Such as Figure 2As shown, in this embodiment, a plurality of elastic locking blocks 6 are evenly distributed along the circumferential direction of the measuring rod 2; the elastic locking blocks 6 evenly distributed in the circumferential direction can effectively avoid stress concentration, so that the elastic locking blocks 6 are more stable and reliable when locked, and the reliability of the device in use is increased.

[0029] As Figure 1 shown, in this embodiment, an electronic digital display scale 3 is further provided on the scale ruler 5; on the basis that the detection device already has the scale ruler 5 for dimension measurement, adding the electronic digital display scale 3 can improve the convenience of dimension data measurement of the device, improve work efficiency, and providing both the scale ruler 5 and the electronic digital display scale 3 on the device for dimension data measurement also increases the reliability of the detection device. When any one of the scale ruler 5 and the electronic digital display scale 3 fails, the detection device can still work normally.

[0030] As Figure 1 shown, in this embodiment, a scale is provided on the measuring rod 2; in addition to reading on the scale ruler 5 and the electronic digital display scale 3, by providing a scale on the measuring rod 2, it is also convenient for the measuring personnel to estimate the thickness data of the subbase layer of the road structure layer inserted deeply according to the scale on the measuring rod 2.

[0031] As Figure 1 shown, in this embodiment, the detection working end of the measuring rod 2 is conical; the detection working end of the measuring rod 2 is used to directly insert deeply into the subbase layer of the road structure layer. The design of the conical structure can make the measuring rod 2 more convenient and easier to insert deeply into the subbase layer of the road structure layer, reduce the workload of the measuring personnel, and improve work efficiency.

[0032] As Figure 1 shown, in this embodiment, the measuring limit plate 4 is perpendicular to the scale ruler 5; it can make the measuring limit plate 4 fit the top surface of the road structure layer, and avoid the slight difference in the observed top surface of the loose paving layer caused by different perspectives of the measuring staff, which may lead to errors in the measured thickness. Therefore, ensuring that the measuring limit plate 4 is perpendicular to the scale ruler 5 can make the measured data more accurate.

[0033] As Figure 2 shown, in this embodiment, the cross-section of the measuring rod 2 is circular, and the diameter of the measuring rod 2 is 20 mm; the diameter size of the measuring rod 2 can be adjusted according to actual needs, and the cross-section of the measuring rod 2 can also be changed to other shapes according to actual use requirements. The measuring rod 2 mainly provides a supporting role for the movement of the scale ruler 5 during the measurement process, which is convenient for data measurement.

[0034] As Figure 1As shown, in this embodiment, the handle 1 is connected to the measuring rod 2 by welding, and the measuring limit plate 4 is connected to the scale ruler 5 by welding. The measuring limit plate 4 is made of alloy steel. The welding connection form is more reliable, suitable for the detection device, and the welding cost is relatively low, which is beneficial to reducing the production and manufacturing cost of the detection device. The alloy steel has good high-temperature resistance and corrosion resistance, and is suitable for the data measurement of the detection device on the road structure layer.

[0035] As Figure 1 shown, in this embodiment, the scale on the scale ruler 5 is from 0 to 500 mm, and the length of the measuring rod 2 is 1000 mm. The scale range on the scale ruler 5 can be adjusted according to the actual use requirements to adapt to data measurement in a larger or smaller range. The length of the measuring rod 2 can also be adjusted according to the actual use requirements to adapt to the measurement of a road structure layer with a greater depth.

[0036] As Figure 2 shown, in this embodiment, the length of the measuring limit plate 4 is 100 mm, the width of the measuring limit plate 4 is 30 mm, and the thickness of the measuring limit plate 4 is 5 mm. During the measurement, making the measuring limit plate 4 fit the top surface of the road structure layer can make the measured data more accurate, reduce errors, and the length, width, and thickness of the measuring limit plate 4 can be adjusted according to the actual use requirements.

[0037] As Figures 1 to 2 shown, in this embodiment, at the beginning of the measurement, first mark the position on the measuring rod 2 where the scale of the scale ruler 5 is 0. Clamp the handle 1, insert the detection end of the measuring rod 2 into the subbase of the road structure layer, and ensure that the measuring limit plate 4 fits the top surface of the road structure layer when reaching the top surface of the subbase. At this time, release the handle 1, the position of the measuring limit plate 4 is fixed, pull out the detection device, and calculate the measurement data by comparing with the previously marked position on the measuring rod 2 where the scale of the scale ruler 5 is 0, or directly read the data according to the electronic digital display ruler 3, and calculate the measurement data according to the scale set on the measuring rod 2.

[0038] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present utility model.
