Description

Technical Field

[0001] The present application relates to the field of asphalt thickness detection, and in particular to a convenient detector for the loose thickness of water-stabilized asphalt paving. Background Art

[0002] During the construction of asphalt pavement, the temperature and thickness of the pavement need to be measured in real time to detect the construction quality of the pavement. The loose paving thickness of the asphalt pavement is a very important technical indicator. During paving, the paving thickness of the pavement should be detected at any time to control the flatness of the pavement. At present, the commonly used operation method basically adopts the traditional direct sampling method, that is, inserting a steel plug into the asphalt pavement and then pulling it out, and then measuring with a ruler to obtain the measurement data of the asphalt pavement thickness.

[0003] However, the traditional sampling method requires the operator to squat to keep the drill upright and insert and pull out the drill before measuring with a ruler, which is time-consuming and labor-intensive, and is prone to errors in reading the measured data results. Utility Model Content

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-2 This application is described in further detail.

[0022] Embodiment 1:

[0023] An embodiment of the present application discloses a convenient detector for the loose paving thickness of water-stable asphalt paving. As Figure 1 shown, it includes a plugging rod 1, a positioning support plate 6, a first fixing block 3, a second fixing block 4, a sliding rod 5 and a sliding block 51. The first fixing block 3 and the second fixing block 4 are symmetrically fixed at opposite ends of the sliding rod 5. One end of the plugging rod 1 is connected to the first fixing block 3. The plugging rod 1 is arranged parallel to the length direction of the sliding rod 5. The sliding block 51 is slidably connected to the sliding rod 5 and is located between the first fixing block 3 and the second fixing block 4. The positioning support plate 6 is connected to the sliding block 51, and the positioning support plate 6 is slidably connected to the plugging rod 1. The end of the plugging rod 1 away from the first fixing block 3 is a conical tip, and the plugging rod 1 is a metal rod, and a steel rod can be selected.

[0024] As Figure 1 shown, a holding handle 31 is fixedly connected to the first fixing block 3. The holding handle 31 and the plugging rod 1 are arranged in a T shape. A digital display 2 is fixedly connected to one end of the holding handle 31. A displacement sensor (not shown in the figure) is built in the sliding block 51. A wire 21 is fixedly connected to the digital display 2. The other end of the wire 21 is connected to the displacement sensor in the sliding block 51. When the sliding block 51 slides along the sliding rod 5, after the displacement sensor detects the sliding stroke of the sliding block 51, the data is timely fed back on the screen of the digital display 2 through the digital display 2.

[0025] As Figure 1 shown, in order to limit the wire 21 and reduce the interference caused by the wire 21 to the detector during the use of the detector, a limit block 9 is fixedly connected to the plugging rod 1. A limit slot 91 is opened on the limit block 9. The middle section of the wire 21 can be placed in the limit slot 91, and the limit slot 91 clamps the wire 21 to realize the tidying and storage of the wire 21.

[0026] As Figure 1 shown, it further includes a connecting rod 52. One end of the connecting rod 52 is fixedly connected to the sliding block 51, and the other end is fixedly connected to the positioning support plate 6, and can be connected by a welding connection method.

[0027] As Figure 1As shown in the figure, it further includes a sliding sleeve 7 and a reset member. The sliding sleeve 7 is slidably sleeved on the plug 1, and the positioning support plate 6 is fixedly connected to the sliding sleeve 7. The reset member is a reset spring 8. One end of the reset spring 8 is connected to the side of the second fixed block 4 away from the first fixed block 3, and the other end of the reset spring 8 abuts against the sliding sleeve 7. When the operator presses down the plug 1 to move, the positioning support plate 6 drives the sliding sleeve 7 to slide relative to the plug 1 and compress the reset spring 8, and at the same time drives the sliding block 51 to slide along the slide bar 5. When the detection is completed and the operator pulls out the plug 1 upward, the sliding sleeve 7 automatically resets under the elastic force of the reset spring 8, thereby driving the positioning support plate 6 and the sliding block 51 to reset.

[0028] As Figure 1 shown, in this embodiment, the positioning support plate 6 is an integrally formed whole, and the plate surface of the positioning support plate 6 is generally triangular from the main perspective, and the plate surface on one side of the lower end is horizontal. In the initial state of the detector, the horizontal plate surface of the positioning support plate 6 and the end of the plug 1 are in the same horizontal plane, which is convenient for the initial positioning before detection.

[0029] Embodiment 2:

[0030] As Figure 2 shown, the length direction of the positioning support plate 6 is perpendicular to the length direction of the plug 1, and the positioning support plate 6 is folded along its own length direction. The positioning support plate 6 includes a first positioning plate 61, a second positioning plate 62 and a third positioning plate 63. The first positioning plate 61 is fixedly connected to the sliding sleeve 7, the second positioning plate 62 is rotatably connected to the side of the first positioning plate 61 away from the sliding sleeve 7, and the third positioning plate 63 is rotatably connected to the side of the second positioning plate 62 away from the first positioning plate 61, and both rotation axes are consistent with the length direction of the plug 1.

[0031] When storing or transporting, the positioning support plate 6 can be folded to reduce the occupied space. When in use, the positioning support plate 6 is unfolded, which is beneficial to increasing the contact area with the positioning surface, improving the positioning accuracy, and effectively improving the use convenience of the detector.

[0032] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
