[0028] 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.

[0029] Please see Figures 1-4In this embodiment of the utility model, a thickness detection device for highway engineering includes a base plate 10. Specifically, four corners of the bottom of the base plate 10 are equipped with traveling wheels 11, and locking plates for braking are installed on the traveling wheels 11. A pulling frame 12 is installed on one side of the top of the traveling wheels 11. The pulling frame 12 consists of a pull rod and two rotating rods. Rotating seats are installed at both ends of the top of the base plate 10. A rotating pin is fixedly connected to the inner wall of the rotating seat. One end of the rotating rod is fixedly connected to the outer wall of the rotating pin. The pull rod is fixedly connected between the two rotating rods. When measurement is required, the pull rod on the pulling frame 12 is pulled. The pull rod drives the rotating pin on the rotating rod to rotate in the rotating seat, rotating the pull rod to the desired position for easy pulling by the staff. The staff pulls the pull rod to move the base plate 10 to the desired position through the traveling wheels 11 at the bottom. The staff steps on the locking plates on the traveling wheels 11 to fix the base plate 10.

[0030] Support frames 20 are fixedly connected to the top two ends of the base plate 10. A first flange is installed at the bottom end of the support frame 20. The first flange is installed on the top of the base plate 10 by bolts. Limiting grooves 21 are opened on the outer wall of the two support frames 20 on opposite sides. Guide grooves 22 are opened on the side wall of the support frame 20. A support plate 30 is slidably connected between the two support frames 20. Limiting sliders are fixedly connected to both ends of the support plate 30. Protrusions are fixedly connected to both ends of the support plate 30 at the limiting sliders. The limiting sliders and protrusions are slidably connected to the inner walls of the limiting grooves 21 and guide grooves 22, respectively. The limiting grooves 21 and guide grooves 22 limit the sliding of the support plate 30. A lifting assembly for driving the support plate 30 to move is installed on the inner wall of the support frame 20. A scale 25 for measuring the height of the support plate 30 is opened on the outer wall of the support frame 20. The lifting assembly adjusts the height of the support plate 30 and applies downward pressure to the support plate 30.

[0031] A drilling assembly for measuring road surface thickness is installed at the bottom of the support plate 30. The drilling assembly includes a second motor 31, a drill rod 33, and a rotating shaft 34. A first frame is installed at the top of the support plate 30. The second motor 31 is fixedly connected to the inner wall of the first frame. The rotating shaft 34 is installed at the output end of the second motor 31. The drill rod 33 is installed at the bottom end of the rotating shaft 34. A through hole 13 is opened at the top of the base plate 10 at the axis of the drill rod 33. A second flange is installed at the adjacent end of the rotating shaft 34 and the drill rod 33. The two second flanges are installed by bolts. When the second motor 31 starts, it drives the drill rod 33 to rotate through the rotating shaft 34. The support plate 30 moves down to provide downward pressure for the drill rod 33. The drill rod 33 passes through the through hole 13 to drill a hole in the road surface.

[0032] A control cylinder 32 is fixedly connected to the bottom end of the support plate 30. The control cylinder 32 and the rotating shaft 34 are located on the same axis. The rotating shaft 34 and the drill rod 33 are rotatably connected to the inner wall of the control cylinder 32. A control component is installed inside the control cylinder 32 to adjust the lifting component through the rotation torque of the rotating shaft 34.

[0033] See Figure 5 The control component includes a measuring ring 40, a fixed disk 41, and a sliding disk 42. The fixed disk 41 is fixedly connected to the top of the outer wall of the rotating shaft 34, and the sliding disk 42 is slidably connected to the bottom of the outer wall of the rotating shaft 34. The outer wall of the rotating shaft 34 has multiple circumferentially arranged limiting grooves 35. The inner wall of the sliding disk 42 has multiple circumferentially arranged limiting blocks 43 fixedly connected. The limiting blocks 43 are slidably connected to the inner wall of the limiting grooves 35. The sliding disk 42 slides in the limiting grooves 35 through the limiting blocks 43, which limit the sliding direction of the sliding disk 42. The measuring ring 40 is installed between the fixed disk 41 and the sliding disk 42. The measuring ring 40 is sleeved on the outer wall of the rotating shaft 34 and has elasticity. When the rotating shaft 34 rotates, the rotating shaft 34 can drive the fixed disk 41 to rotate. Under the action of the torque of the fixed disk 41, the measuring ring 40 is driven to twist and deform. At this time, the sliding disk 42 can slide and move upward on the rotating shaft 34 with the deformation of the measuring ring 40.

[0034] See Figure 2 and Figure 3 The lifting assembly includes a first motor 23 and a lead screw 24. A second frame is mounted on the top of one support frame 20. The first motor 23 is fixedly connected to the inner wall of the second frame. The lead screw 24 is rotatably connected to the inner wall of the limiting groove 21 on the support frame 20 and is installed at the output end of the first motor 23. A guide rod is fixedly connected to the inner wall of the limiting groove 21 on the other support frame 20. A threaded hole is opened on the limiting slider at one end of the support plate 30, and a first sliding hole is opened on the limiting slider at the other end of the support plate 30. The lead screw 24 is threadedly connected to the inner wall of the threaded hole on the support plate 30, and the guide rod is slidably connected to the inner wall of the first sliding hole. When the first motor 23 is started, it drives the lead screw 24 to rotate. The rotation of the lead screw 24 causes the threaded support plate 30 to slide between the support frames 20. The sliding of the guide rod in the first sliding hole guides the support plate 30 to slide, thereby driving the support plate 30 to rise and fall.

[0035] See Figure 6 A fixing plate 50 is fixedly connected to the middle of the inner wall of the control cylinder 32. The fixing plate 50 has a through second sliding hole. A sliding rod 51 is slidably connected to the inner wall of the second sliding hole. A pressure ball 53 is fixedly connected to the bottom end of the sliding rod 51. The pressure ball 53 is in contact with the top of the sliding disk 42. A connecting disk 52 is fixedly connected to the bottom of the outer wall of the fixing plate 50. A first spring 54 is fixedly connected to the opposite side of the connecting disk 52 and the fixing plate 50. The first spring 54 is sleeved on the outer wall of the sliding rod 51. When the sliding disk 42 moves upward, the pressure ball 53 is squeezed and drives the sliding rod 51 to move upward. At this time, the first spring 54 is squeezed and contracted. When the sliding disk 42 moves downward, the sliding rod 51 and the pressure ball 53 are reset under the elastic force of the first spring 54.

[0036] See Figure 7The control assembly also includes a sliding sleeve 61, an electrode plate 63, and an electrode ring 64. An adjusting cylinder 60 is fixedly connected to the top of the fixed plate 50 at the axis position of the sliding rod 51. A through hole is opened in the inner wall of the sliding sleeve 61. The sliding sleeve 61 is slidably connected to both ends of the adjusting cylinder 60. The sliding rod 51 passes through the through hole of the bottom sliding sleeve 61. A pressing plate 55 is fixedly connected to the top of the sliding rod 51. The pressing plate 55 is located between the two sliding sleeves 61. The electrode plate 63 is fixedly connected to the outer ring of the sliding sleeve 61. The electrode ring 64 is fixedly connected to both ends of the outer wall of the adjusting cylinder 60 and located inside the sliding sleeve 61. The two sets of electrode plates 63 and electrode rings 64 are connected in parallel in the control circuit of the first motor 23. That is, when any set of electrode plates 63 and electrode rings 64 are connected, the first motor 23 can be started. When the rotating shaft 34 is stationary, the pressing plate 55 presses the bottom sliding sleeve 61, and the bottom electrode plate 63 and electrode ring 64 are connected.

[0037] A second spring 62 is fixedly connected to the opposite side of the top sliding sleeve 61 and the adjusting cylinder 60. A damping rod 66 is fixedly connected to the opposite side of the bottom sliding sleeve 61 and the adjusting cylinder 60. A third spring 65 is sleeved on the outer wall of the damping rod 66. The two ends of the third spring 65 are fixedly connected to the opposite side of the sliding sleeve 61 and the adjusting cylinder 60, respectively. When the rotating shaft 34 rotates and drives the sliding disk 42 to move upward, the sliding rod 51 and the pressing plate 55 move upward and press the top sliding sleeve 61. The top electrode plate 63 can then contact the electrode ring 64 to connect the circuit. At this time, the bottom sliding sleeve 61 resets under the elastic force of the third spring 65. The damping rod 66 can reduce the reset speed to avoid the bottom sliding sleeve 61 resetting too quickly, which would cause the first motor 23 to form an open circuit and affect the drive of the first motor 23.

[0038] The working principle of this utility model is as follows: When measurement is required, the base plate 10 is moved to the desired position, and the first motor 23 drives the lead screw 24 to rotate, which drives the threaded support plate 30 to move, and the drill rod 33 is moved to contact the road surface. The reading of the support plate 30 at the scale 25 is recorded at this time. Then the second motor 31 is turned on, and the drill rod 33 is driven to rotate through the rotating shaft 34. The drill rod 33 rotates to drill a hole in the road surface.

[0039] When the first motor 23 moves, the extrusion plate 55 presses against the bottom sliding sleeve 61, and the bottom electrode plate 63 moves to the contact range of the electrode ring 64, connecting the circuit of the first motor 23. When the second motor 31 starts drilling, the measuring ring 40 deforms under the torque of the rotating fixed disk 41, driving the sliding disk 42 to move on the rotating shaft 34. The sliding disk 42 presses against the pressure ball 53, which drives the fixed plate 50 and the extrusion plate 55 to move. The extrusion plate 55 moves out of the bottom sliding sleeve 61, and the sliding sleeve 61 resets under the elastic force of the third spring 65, and the reset speed is reduced under the action of the damping rod 66. The moving part presses against the top sliding sleeve 61, causing it to move and move the electrode plate 63 to the contact range of the electrode ring 64. The circuit at the first motor 23 continues to be connected, causing the support plate 30 to descend. When the road surface is penetrated, the torque on the rotating shaft 34 decreases, the sliding disk 42 moves down, and the pressing plate 55 moves between the two sliding sleeves 61 under the elastic force of the first spring 54. The top sliding sleeve 61 resets under the elastic force of the second spring 62. At this time, a circuit is broken at the first motor 23, and the support plate 30 stops descending. The reading of the support plate 30 at the scale 25 is recorded, and the road surface thickness is obtained by subtracting the two readings.

[0040] When in use, this utility model, through the set base plate 10, drilling assembly and control assembly, can measure the thickness of the road surface according to the different torques when drilling the road surface. The operator only needs to start the first motor 23 and the second motor 31 to carry out the measurement, which simplifies the operation steps, eliminates the need to observe inside the borehole, further improves the convenience of detection, and can move the equipment with the base plate 10 to the required position, making it convenient to detect various positions of the road surface.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
