Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a loose paving thickness detection ruler for asphalt pavement construction. Background Art

[0002] Loose lay thickness refers to the thickness of the asphalt mixture after it is spread by the paver before compaction. With an increasing number of highways being constructed using asphalt mixtures, checking the loose lay thickness of the asphalt mixture during construction is essential. Because the loose lay thickness of the asphalt mixture determines the total thickness of the pavement after compaction, insufficient loose lay thickness often leads to the following problems: insufficient total thickness of the asphalt after adequate compaction, while insufficient total thickness results in excessive porosity in the pavement structure, which can easily lead to early water damage.

[0003] At present, the main method used is the traditional measurement method, which is to use manpower to insert a steel bar into the loose asphalt pavement, press it with the hand to the height close to the asphalt surface and then pull it out, and then use a ruler to measure the number to obtain the loose thickness of the asphalt pavement. For example, the patent application with the authorization announcement number CN202928498U and the name of an asphalt pavement construction loose thickness inspection instrument has an inspection rod with a tip for easy insertion into the asphalt pavement and a handle at the other end. The inspection rod is axially engraved with a scale, and a cursor that can slide axially and be fixed is provided on the inspection rod. During use, the existing measuring device is prone to skew when the steel bar is inserted, which affects the accuracy of the measurement. At the same time, the temperature of the uncompacted asphalt mixture is relatively high, and safety accidents such as asphalt burns are prone to occur during operation. Utility Model Content

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-5 As shown, the embodiment of the present invention provides a loose paving thickness detection ruler for asphalt pavement construction, including a detection rod 1, a detection frame 2 and a motion detection part 3. The lower end of the detection rod 1 is convenient for inserting the tip 11 of the asphalt pavement, and the upper end of the detection rod 1 is provided with an operating handle 12. The detection frame 2 includes a base 21 and a vertical frame 22 arranged on the base 21. The bottom of the base 21 is provided with a roller part 23. The vertical frame 22 includes two vertical rods 24 arranged in parallel. The lower ends of the vertical rods 24 are fixedly connected to the base 21, and the upper ends of the vertical rods 24 are connected to a pushing cross bar 25. The motion detection part 3 includes a moving cylinder 31 and a horizontal moving plate 32 arranged at the top of the moving cylinder 31. The horizontal moving plate 32 is provided with a mounting hole, and the mounting hole is slidably sleeved on the vertical rod 24. The lower end of the moving cylinder 31 is provided with a horizontal bottom plate 33. The interior of the moving cylinder 31 forms a motion channel 311 for the detection rod 1 to move therein. The detection rod is provided with a scale mark 15 along its axial direction, and the horizontal moving plate 32 is provided with a scale alignment mark.

[0028] Specifically, since the temperature of the uncompacted asphalt mixture is relatively high, in this embodiment, the components in contact with the asphalt mixture are all supported by steel materials, such as the detection rod 1, the roller member 23, and the horizontal base plate 33, which are all made of steel materials. The length of the detection rod 1 is set according to actual needs. The lower end of the detection rod 1 is a pointed end 11 so that the detection rod 1 can be easily inserted into the asphalt pavement. An operating handle 12 is provided at the upper end of the detection rod 1, and the operating handle 12 is provided for hand operation by the staff during the detection process. The detection part includes a base 21 and a vertical frame 22 arranged on the base 21. The base 21 can be a steel plate or an iron plate. A roller part 23 is arranged at the bottom of the base 21. Preferably, there are four roller parts 23, and the four roller parts 23 are arranged at each corner of the base 21. By arranging the roller parts 23, the movement of the detection frame 2 can be facilitated. The vertical frame 22 is arranged on one side of the base 21. The vertical frame 22 includes two parallel vertical rods 24. The vertical rod 24 is a steel pipe. The lower end of the vertical rod 24 is welded and fixed to the base 21. The upper end of the vertical rod 24 is provided with a pushing cross bar 25. In this way, during use, the staff pushes the pushing cross bar 25 to enable the detection frame 2 and the motion detection part 3 and the detection rod 1 located on the detection frame 2 to move on the construction road surface.

[0029] In this embodiment, the motion detection member 3 is used in conjunction with the detection rod 1. The motion detection member 3 includes a hollow motion cylinder 31. The motion cylinder 31 can be a steel pipe with a larger diameter. The interior of the motion cylinder 31 is hollow to form a motion channel 311. The size of the motion channel 311 is slightly larger than the size of the detection rod 1. A horizontal motion plate 32 is provided on the top of the motion cylinder 31. A mounting hole is provided on the horizontal motion plate 32. A sliding sleeve is provided in the mounting hole. The sliding sleeve is provided on the vertical rod 24. In this way, the horizontal motion plate 32 can move up and down along the vertical rod 24. A horizontal bottom plate 33 is provided at the lower end of the moving cylinder 31. The horizontal bottom plate 33 is a steel plate. A bottom through hole connected to the motion channel 311 is provided on the horizontal bottom plate 33, so that the lower end of the detection rod 1 can extend from the motion channel 311 and the bottom through hole of the horizontal bottom plate 33. The detection rod 1 is provided with a scale mark 15 along the axial direction. From the bottom to the top of the detection rod 1, the scale value of the scale mark 15 gradually increases. At the same time, a scale alignment mark is provided on the horizontal motion plate 32, and the scale alignment mark is used to read the corresponding scale mark 15.

[0030] In this embodiment, in the initial state, the horizontal bottom plate 33 is placed on the base 21, and the lower end of the detection rod 1 is stored in the movement channel 311 and the bottom through hole, and the lower end of the detection rod 1 and the bottom of the horizontal bottom plate 33 are located on the same plane. The use process is as follows:

[0031] In the first step, the detection frame 2 is moved to the position to be detected by the roller member 23. Then, the motion detection member 3 is adjusted so that the motion cylinder 31 and the horizontal motion plate 32 move downward along the vertical rod 24 until the horizontal base plate 33 contacts the asphalt on the road surface. At this time, the tip 11 at the bottom of the detection rod 1 also contacts the asphalt road surface. At this time, the value H1 of the scale mark 15 on the detection rod 1 corresponding to the scale alignment mark is read.

[0032] In the second step, the staff presses down the operating handle 12 of the detection rod 1, so that the detection rod 1 is gradually inserted into the asphalt pavement until the detection rod 1 encounters greater resistance and cannot continue to move downward. The value H2 of the scale mark 15 on the detection rod 1 corresponding to the scale alignment mark is recorded at this time. The difference between H2 and H1 is the height that the detection rod 1 descends during the detection process, that is, the thickness of the loose asphalt pavement.

[0033] In the third step, after one position detection is completed, the detection rod 1, the horizontal bottom plate 33 and the moving cylinder 31 are restored to their initial states, and then the detection frame 2 can be moved to another position for detection.

[0034] The asphalt pavement construction loose paving thickness detection ruler provided by the embodiment of the present invention includes a detection rod 1, a detection frame 2 and a motion detection member 3. The detection frame 2 includes a base 21 and a vertical frame 22 arranged on the base 21. The vertical frame 22 includes two vertical rods 24 arranged in parallel. The motion detection member 3 includes a motion cylinder 31 and a horizontal motion plate 32 arranged on the top of the motion cylinder 31. The horizontal motion plate 32 is slidably sleeved on the vertical rod 24. The lower end of the motion cylinder 31 is provided with a horizontal bottom plate 33. The interior of the motion cylinder 31 forms a motion channel 311 for the detection rod 1 to move therein. The detection rod 1 is provided with a scale mark 15 along its axial direction. When the asphalt pavement is detected, the ... The cylinder 31 first moves along the vertical rod 24 until the horizontal bottom plate 33 contacts the asphalt on the road surface. At this time, the horizontal bottom plate 33 is parallel to the asphalt road surface. Then the staff presses down the detection rod 1, so that the detection rod 1 moves along the axis direction of the moving cylinder 31 and is inserted into the asphalt road surface. During this process, the detection rod 1 is inserted into the asphalt road surface in a direction perpendicular to the asphalt road surface, and will not be skewed, which can improve the accuracy of the detection. During the detection process, the thickness of the asphalt road surface can be known by matching the scale mark 15 on the detection rod 1 with the scale alignment mark on the horizontal moving plate 32. The detection and reading are simple, and no contact with the asphalt road surface is required, which improves the safety of the operation.

[0035] In this embodiment, preferably, the horizontal bottom plate 33 is a circular plate, and strip pieces 34 are symmetrically provided on the opposite sides of the circular plate. The strip piece 34 is integrally provided with the circular plate, and a circular opening 211 is provided on the base 21. The size of the circular opening 211 is consistent with that of the circular plate so that the circular plate can pass through it. Strip openings 212 are provided on the opposite sides of the circular opening 211, and the strip openings 212 are provided corresponding to the strip piece 34. The strip openings 212 are connected to the circular opening 211, that is, the circular opening 211 and the strip opening 212 form an opening structure. In this way, during use, when the moving cylinder 31 moves downward, the circular plate and the strip piece 34 can pass through the circular opening 211 and the strip opening 212 respectively.

[0036] In this embodiment, preferably, two strip support grooves 213 are provided downwardly corresponding to the upper surface of the base 21, and the strip support grooves 213 are connected to the circular opening 211. The two strip pieces 34 can be placed in the strip support grooves 213 respectively. In the initial state, the strip piece 34 on the horizontal bottom plate 33 is located in the strip support grooves 213, so that the base 21 supports the circular plate and the moving cylinder 31, and the circular plate is separated from the asphalt pavement. When inspection is required, the moving cylinder 31 and the circular plate are first lifted up so that the strip piece 34 leaves the strip support grooves 213, and then the moving cylinder 31 is rotated a certain angle so that the strip piece 34 corresponds to the strip opening 212. Finally, the moving cylinder 31 moves downward, and the circular plate and the strip piece 34 can pass through the circular opening 211 and the strip opening 212 respectively until the circular plate contacts the asphalt on the road surface. On the contrary, after the detection is completed, the moving cylinder 31 and the circular plate are lifted until the circular plate passes through the circular opening 211 to the top of the base 21, and the moving cylinder 31 is rotated a certain angle so that the strip piece 34 corresponds to the strip support groove 213. Then the moving cylinder 31 moves downward, and the strip pieces 34 are placed in the strip support grooves 213 respectively.

[0037] In this embodiment, preferably, a rotating connector is provided on the top of the moving cylinder 31, and a circular connecting port is provided on the horizontal moving plate 32. The rotating connector can be rotatably installed on the circular connecting port, so that the moving cylinder 31 can be rotatably installed on the horizontal moving plate 32.

[0038] In this embodiment, preferably, the detection rod 1 is provided with an annular moving part 13, and the annular moving part 13 is provided with a radial sliding block 14. The number of the radial sliding blocks 14 can be two, three or more, and the radial sliding blocks 14 are arranged in sequence along the circumference of the annular moving part 13. An axial sliding groove 312 is provided on the inner wall of the motion channel 311. The number of the axial sliding grooves 312 is consistent with the number of the radial sliding blocks 14. The radial sliding blocks 14 are restricted in sliding in the axial sliding grooves 312 in a one-to-one manner. The radial sliding blocks 14 cooperate with the axial sliding grooves 312 so that the detection rod 1 and the annular moving part 13 can only move along the motion channel 311. The moving cylinder 31 moves up and down in the axial direction, and the detection rod 1 cannot rotate relative to the moving cylinder 31. This arrangement has two effects: first, the horizontal bottom plate 33 is attached to the asphalt pavement, and the moving cylinder 31 is perpendicular to the horizontal bottom plate 33. The detection rod 1 can only move up and down along the axial direction of the moving cylinder 31, that is, the detection component can only be inserted into the asphalt perpendicular to the direction of the asphalt pavement, thereby improving the accuracy of the detection; second, when the moving cylinder 31 needs to be rotated, the staff rotates the operating handle 12, and the detection rod 1 will drive the moving cylinder 31 to rotate together on the horizontal moving plate 32 until the moving cylinder 31 rotates to a suitable angle.

[0039] In this embodiment, preferably, a positioning hole is provided on the detection rod 1, and the positioning hole can pass through the detection rod 1. A positioning pin 35 is detachably provided in the positioning hole. There can be an arc-shaped side plate on the top of the moving cylinder 31, and the positioning pin 35 is movably provided on the arc-shaped side plate. When the detection rod 1 moves so that the positioning hole corresponds to the positioning pin 35, the positioning pin 35 can be inserted into the positioning hole, thereby fixing the detection rod 1 on the moving cylinder 31. At this time, the detection rod 1 is in the initial state, and the lower end of the detection rod 1 and the bottom of the horizontal bottom plate 33 are located on the same plane. During the detection process, when the moving cylinder 31 and the horizontal moving plate 32 move downward along the vertical rod 24 until the horizontal bottom plate 33 contacts the asphalt on the road surface, the positioning pin 35 is pulled out, and then the detection rod 1 can be inserted into the asphalt road surface for detection.

[0040] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
