The measurement time and location are also selected by the construction workers themselves, and the measurement point is a single point measurement. The detection method has the problems of low efficiency and poor representativeness.

[0005] According to a paving machine with a material cleaning structure disclosed in the patent number CN219908461U, the device can effectively solve the problem that when the paving machine is used, it is necessary to use a paving roller to pave the ground, and a large amount of asphalt residue will be attached to the surface of the paving roller after the operation is completed. If these asphalt residues are not cleaned in time, it will inevitably affect the next use;

[0006] However, the device also lacks a device to measure the paving thickness in time during paving, which is rather troublesome during paving and requires workers to perform individual measurements. The detection method has problems of low efficiency and poor representativeness. Utility Model Content

[0027] See also Figures 1 to 4 The electric extension rod 2 can be fixed by the support column 1, and the paving purpose can be achieved by the first push plate 3 and the second push plate 4. The second push plate 4 can slide inside the first push plate 3. By adjusting the position of the second push plate 4, the paving area of ​​the device can be adjusted, which can make the device suitable for different working conditions, and at the same time can improve the working efficiency of the device and effectively increase the practicality of the device.

[0028] A thickness measuring mechanism 5 is arranged outside the support column 1, and the thickness measuring mechanism 5 includes a first bidirectional threaded rod 501, and a first bevel gear 502 is fixedly connected to the outer surface of the first bidirectional threaded rod 501, and a second bevel gear 503 meshing with the first bevel gear 502 is arranged inside the support column 1, and two symmetrical threaded columns 504 are threadedly connected to the outer surface of the first bidirectional threaded rod 501.

[0029] See also Figure 3The rotation of the second bevel gear 503 can drive the first bevel gear 502 to rotate, and then the first bidirectional threaded rod 501 can be driven to rotate. The rotation of the first bidirectional threaded rod 501 can drive the two threaded columns 504 to move. The outer surface of the threaded column 504 is polished, which can reduce the wear caused by the sliding of the threaded column 504 and can effectively increase the service life of the device. The lengths of the two threaded columns 504 are not the same. One threaded column 504 can be above the paved surface, and the other threaded column 504 is above the initial ground.

[0030] The bottom surface of the threaded column 504 is fixedly connected to two fixed columns 505, the inner wall of the fixed column 505 is slidably connected to a sliding column 506, the front of the fixed column 505 is fixedly connected to a fixed frame 507, the inner wall of the fixed frame 507 is slidably connected to an insertion rod 508, and the fixed column 505 and the sliding column 506 are both plugged into the insertion rod 508.

The pull rope sensor 509 can be used to measure the angle of the connecting rope 5010, so that the result measured by the pull rope sensor 509 can be transmitted to the detection device, and the difference in angle can be converted into a change in length, so as to achieve the purpose of thickness detection. The two connecting ropes 5010 are the same length to ensure the accuracy of the detection result. The pull rope sensor 509 is an existing device and a commonly used detection device on the market.

The passivation treatment on the outer surface of the first turntable 10 can effectively prevent the staff from being scratched.

[0038] A driving vehicle 11 is arranged outside the support column 1, and two sets of tires 12 are installed on the bottom of the driving vehicle 11. The driving vehicle 11 and the tires 12 can realize the purpose of driving the device to move and work, making the operation of the device more convenient and quick.

[0039] Two connecting rods 13 are fixedly connected to the right side of the driving vehicle 11, and the right ends of the two connecting rods 13 are fixedly connected to the left side of the support column 1. A reinforcing rod 14 is arranged on the outside of the support column 1, and the two ends of the reinforcing rod 14 are respectively fixedly connected to the outer surfaces of the two connecting rods 13. The connecting rod 13 and the reinforcing rod 14 can be used to connect the support column 1 and the driving vehicle 11. The connecting rod 13 and the driving vehicle 11 are connected by welding, which can make the connection more stable. The reinforcing rod 14 can increase the stability of the connecting rod 13 to avoid the connecting rod 13 from breaking during use, which can effectively increase the safety of the device.

[0040] The upper surface of the second bevel gear 503 is fixedly connected with a rotating rod 15, the top of the rotating rod 15 passes through the supporting column 1 and extends to the outside of the supporting column 1, and the top of the rotating rod 15 is fixedly connected with a second rotating disk 16. The rotating rod 15 and the second rotating disk 16 can make it more convenient for the staff to rotate the second bevel gear 503. The outer surface of the second rotating disk 16 is passivated to prevent the staff from being scratched. The outer surface of the second rotating disk 16 can be provided with a protective cover, which can effectively increase the comfort of the staff.

[0041] Two reinforcing ribs 17 are fixedly connected to the outer surface of the electric extension rod 2, and the bottom surfaces of the two reinforcing ribs 17 are fixedly connected to the upper surface of the first push plate 3. The reinforcing ribs 17 can strengthen the connection stability between the electric extension rod 2 and the first push plate 3, prevent the first push plate 3 from falling off during use, and effectively increase the safety of the device.

[0042] Working principle: When the device is in use, the height of the first push plate 3 is first adjusted according to the needs. First, the electric extension rod 2 needs to be started. The purpose of adjusting the height of the first push plate 3 can be achieved through the electric extension rod 2. Then, the first turntable 10 is rotated, which can drive the second bidirectional threaded rod 8 to rotate. With the rotation of the second bidirectional threaded rod 8, the second push plate 4 can be driven to move through the threaded block 9, thereby achieving the purpose of adjusting the paving area of ​​the device. Then, the position of the pull rope sensor 509 is adjusted according to the needs. First, the second turntable 16 needs to be rotated, and then the second bevel gear 503 can be driven to rotate through the rotating rod 15. The rotation of the second bevel gear 503 can drive the first bevel gear 502 to rotate, thereby driving the first bidirectional threaded rod 501 to rotate. The rotation of the first bidirectional threaded rod 501 can drive the two threaded columns 504 to move. The movement of the threaded column 504 can drive the movement of the fixed column 505, and the movement of the fixed column 505 can drive the sliding column 506, thereby achieving the purpose of adjusting the position of the pull-rope sensor 509, and then pulling the pull plate 6, and then pulling the insertion rod 508 out from the inside of the fixed column 505 and the sliding column 506, and then adjusting the position of the sliding column 506, thereby achieving the purpose of adjusting the height of the pull-rope sensor 509. When the device is paving, one of the two pull blocks 5011 is on the ground after paving, and the other is on the original ground, so that the angles of the two connecting ropes 5010 will be different. The pull-rope sensor 509 can be used to measure the angle of the connecting rope 5010, so that the measurement result of the pull-rope sensor 509 can be transmitted to the detection device, thereby achieving the purpose of measuring the paving thickness.
