Description
Technical Field
[0001] This utility model relates to the field of highway construction technology, and more specifically to an auxiliary measuring device for asphalt pavement thickness. Background Technology
[0002] Asphalt pavement thickness measurement is an important part of road construction and maintenance. Loose paving thickness refers to the thickness of the asphalt mixture after it has been spread by a paver before compaction. In order to ensure the quality of the ground, it is essential to test the loose paving thickness of asphalt during the construction process.
[0003] Current methods for detecting asphalt thickness on pavements typically involve workers manually inserting a measuring needle into the asphalt pavement. However, asphalt pavements have a certain resistance, making the operation time-consuming and laborious. Furthermore, manually pressing down on the asphalt pavement can apply significant pressure, potentially causing it to collapse and thus reducing the quality of the asphalt pavement construction. Utility Model Content
[0004] The purpose of this invention is to solve the problem that the existing method of detecting asphalt pavement thickness generally involves workers manually inserting a measuring needle into the asphalt pavement, which is time-consuming and labor-intensive. The invention provides an auxiliary measuring device for asphalt pavement thickness.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An auxiliary measuring device for asphalt pavement thickness includes a base, a U-shaped frame fixedly connected to the top of the base, a measuring component on the top of the U-shaped frame, a rotating rod on the top of the U-shaped frame, second moving grooves symmetrically formed on the inner walls of both sides of the U-shaped frame, worm gears symmetrically fixedly sleeved at both ends of the rotating rod, a worm wheel meshing on one side of the worm gear, a reciprocating screw fixedly connected to the bottom of the worm wheel, a second moving block threadedly connected to one end of the reciprocating screw in the second moving groove, a horizontal plate fixedly connected between the two second moving blocks, a measuring rod fixedly connected to the middle of the bottom of the horizontal plate, stabilizing components symmetrically arranged on the bottom of both sides of the U-shaped frame, and buffering components symmetrically arranged on the bottom of the inner walls of both sides of the U-shaped frame.
[0007] As a further description of the above technical solution, the stabilizing component includes a fixed plate fixedly connected to the bottom of one side of the U-shaped frame. A groove is provided on one side of the fixed plate, and symmetrical locking holes are provided on one side of the groove. A slider is slidably connected to the inner wall of the groove. A first moving groove is provided on one side of the slider. A guide rod is fixedly installed at the bottom of the first moving groove. A first moving block is movably sleeved at one end of the guide rod. A return spring is sleeved at the end of the guide rod near the first moving block. A locking rod is fixedly connected to one side of the first moving block. The locking rod passes through the slider and extends into the locking hole. A first spring rod is fixedly connected to the bottom of the slider. A counterweight is fixedly connected to the bottom of the first spring rod.
[0008] As a further description of the above technical solution, the outer end of the lever is rounded and adapted to the locking hole, and a buffer pad is fixedly connected to the bottom of the counterweight.
[0009] As a further description of the above technical solution, the buffer assembly includes sliding grooves symmetrically opened at the bottom of the inner walls on both sides of the U-shaped frame. A second spring rod is fixedly installed inside the sliding groove, a sliding block is fixedly connected to the top of the second spring rod, and a U-shaped buffer block is fixedly connected to the top of the sliding block.
[0010] As a further description of the above technical solution, a scale line is fixedly connected to one side of the U-shaped frame, and a pointer is fixedly connected to one side of the horizontal plate.
[0011] As a further description of the above technical solution, the base has a through hole at the top, and the bottom end of the reciprocating lead screw is connected to the U-shaped frame bearing.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model, by incorporating a measuring component, allows for the following operation: Rotating the rotating rod drives the worm gear to rotate, and the meshing of the worm gear and worm wheel drives the reciprocating screw to rotate. The reciprocating screw then moves the second moving block down along the second moving groove, thereby moving the horizontal plate down and subsequently the measuring rod down to insert into the road surface at the measurement location. When the measuring rod can no longer move downwards, the scale line corresponding to the pointer's position is read, thus determining the loose asphalt pavement thickness at that location. This completes the measurement of the loose asphalt pavement thickness. The operation is simple and convenient, making the measurement process more efficient. Furthermore, the stable pressure application during the measurement process avoids damage to the asphalt pavement, enhancing the device's practicality.
[0014] 2. This utility model, by incorporating a stabilizing component, allows the device to be placed on the asphalt pavement to be tested. Pressing the first moving block causes it to slide along the first moving groove, squeezing the guide rod and causing the locking rod to move inward and disengage from the locking hole. After releasing the limit on the slider, the slider is slid downward until it reaches its lowest point. Releasing the first moving block allows the locking rod to engage in the locking hole, causing the counterweight fixed at the bottom of the first spring rod to move downward and adhere to the ground. This makes the device more stable and facilitates subsequent measurement operations. Attached Figure Description

[0020] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.
[0021] This utility model provides an auxiliary measuring device for asphalt pavement thickness. Please refer to [link / reference]. Figure 1-4As shown, the device includes a base 1 with a through hole at the top. A U-shaped frame 2 is fixedly connected to the top of the base 1. A measuring component 5 is installed on the top of the U-shaped frame 2. The measuring component 5 includes a rotating rod 51 installed on the top of the U-shaped frame 2. Second moving grooves 52 are symmetrically provided on the inner walls of both sides of the U-shaped frame 2. Worms 53 are symmetrically fixedly sleeved at both ends of the rotating rod 51. A worm wheel 54 is meshed on one side of the worm wheel 53. A reciprocating screw 55 is fixedly connected to the bottom of the worm wheel 54. The bottom end of the reciprocating screw 55 is connected to a bearing of the U-shaped frame 2. A second moving block 56 is threadedly connected to one end of the reciprocating screw 55 located in the second moving groove 52. A horizontal plate 57 is fixedly connected between the two second moving blocks 56. A measuring rod 58 is fixedly connected to the middle of the bottom of the horizontal plate 57. Stabilizing components 3 are symmetrically provided on the bottom of both sides of the U-shaped frame 2. Buffering components 4 are symmetrically provided on the bottom of the inner walls of both sides of the U-shaped frame 2.
[0022] In this embodiment of the application, when it is necessary to measure the loose thickness of asphalt pavement, the device is first placed on the asphalt pavement to be tested. Then, by pressing the first moving block 38, the first moving block 38 slides along the first moving groove 35 to squeeze the guide rod 36, thereby driving the clamping rod 39 to move inward and disengage from the clamping hole 33. After releasing the limit on the slider 34, the slider 34 is slid down. After the slider 34 slides to the lowest end, the first moving block 38 is released, so that the clamping rod 39 is engaged in the clamping hole 33. This causes the counterweight block 311 fixed at the bottom of the first spring rod 310 to move down and fit against the ground, thereby making the device more stable.
[0023] Subsequently, by rotating the rotating rod 51, the rotating rod 51 drives the worm 53 to rotate. The meshing of the worm 53 and the worm wheel 54 drives the reciprocating screw 55 to rotate. The reciprocating screw 55 drives the second moving block 56 to move down along the second moving groove 52, thereby driving the cross plate 57 to move down, and then driving the measuring rod 58 to move down and insert into the road surface at the position to be measured. When the measuring rod 58 can no longer move down, the scale line 6 corresponding to the position of the pointer 7 at this time is read, and the loose asphalt pavement thickness at this position can be measured, thus completing the measurement of the loose asphalt thickness.
[0024] Furthermore, the stabilizing component 3 includes a fixed plate 31 fixedly connected to the bottom of one side of the U-shaped frame 2. A groove 32 is provided on one side of the fixed plate 31, and a locking hole 33 is symmetrically provided on one side of the groove 32. A slider 34 is slidably connected to the inner wall of the groove 32. A first moving groove 35 is provided on one side of the slider 34. A guide rod 36 is fixedly installed at the bottom of the first moving groove 35. A first moving block 38 is movably sleeved at one end of the guide rod 36. A return spring 37 is sleeved at the end of the guide rod 36 near the first moving block 38. A locking rod 39 is fixedly connected to one side of the first moving block 38. The locking rod 39 passes through the slider 34 and extends into the locking hole 33. A first spring rod 310 is fixedly connected to the bottom of the slider 34. A counterweight 311 is fixedly connected to the bottom of the first spring rod 310. The outer end of the locking rod 39 is rounded and adapted to the locking hole 33. A buffer pad is fixedly connected to the bottom of the counterweight 311.
[0025] In use, pressing the first moving block 38 causes it to slide along the first moving groove 35, squeezing the guide rod 36. This causes the locking rod 39 to move inward and disengage from the locking hole 33, releasing the limit on the slider 34. The slider 34 is then slid downward until it reaches its lowest point. The first moving block 38 is then released, allowing the locking rod 39 to engage in the locking hole 33. This causes the counterweight 311, fixed at the bottom of the first spring rod 310, to move downward and fit against the ground, making the device more stable and facilitating the detection of asphalt pavement thickness.
[0026] Furthermore, the buffer assembly 4 includes symmetrical sliding grooves 41 on the bottom of the inner walls on both sides of the U-shaped frame 2. A second spring rod 42 is fixedly installed inside the sliding groove 41. A sliding block 43 is fixedly connected to the top of the second spring rod 42. A U-shaped buffer block 44 is fixedly connected to the top of the sliding block 43.
[0027] During use, as the measuring rod 58 moves downward, the horizontal plate 57 presses against the U-shaped buffer block 44 and continues to move downward, thereby driving the sliding block 43 to move downward along the sliding groove 41 and press against the sliding block 43. This facilitates a buffering effect when the measuring rod 58 is inserted into the asphalt pavement, thus improving the service life of the measuring rod 58.
[0028] Furthermore, a scale line 6 is fixedly connected to one side of the U-shaped frame 2, and a pointer 7 is fixedly connected to one side of the horizontal plate 57.
[0029] The working principle of this utility model is as follows: When it is necessary to measure the loose thickness of asphalt pavement, the device is first placed on the asphalt pavement to be tested. Then, by pressing the first moving block 38, the first moving block 38 slides along the first moving groove 35 to squeeze the guide rod 36, thereby driving the clamping rod 39 to move inward and disengage from the clamping hole 33. After releasing the limit on the slider 34, the slider 34 is slid down. After the slider 34 slides to the lowest end, the first moving block 38 is released, so that the clamping rod 39 is engaged in the clamping hole 33. This causes the counterweight block 311 fixed at the bottom of the first spring rod 310 to move down and fit against the ground, thereby making the device more stable.
[0030] Subsequently, by rotating the rotating rod 51, the rotating rod 51 drives the worm 53 to rotate. The meshing of the worm 53 and the worm wheel 54 drives the reciprocating screw 55 to rotate. The reciprocating screw 55 drives the second moving block 56 to move down along the second moving groove 52, thereby driving the horizontal plate 57 to move down, and then driving the measuring rod 58 to move down and insert into the road surface at the position to be measured. When the measuring rod 58 can no longer move down, the scale line 6 corresponding to the position of the pointer 7 at this time is read, and the loose asphalt pavement thickness at this position can be measured, thus completing the measurement of the loose asphalt thickness.
[0031] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
