Description

Technical Field

[0001] The utility model relates to the technical field of asphalt paving, in particular to a temperature measuring mechanism for asphalt pavement paving. Background Art

[0002] An asphalt pavement is a pavement structure with a certain thickness of asphalt mixture paved on a flexible base and a semi-rigid base. A paver is a basic construction equipment for asphalt pavement paving operations, which is used to evenly lay asphalt on the road surface. When carrying out paving operations, the temperature of the asphalt mixture is crucial for the quality of the road surface. If the asphalt temperature is too high or too low, it will affect the fluidity and adhesiveness of the asphalt, thereby affecting the compactness and durability of the road surface. The temperature measuring mechanism can monitor the temperature of the asphalt in real time, helping the operator adjust the working parameters of the paving equipment in a timely manner, so that the asphalt can be paved within the optimal temperature range, ensuring the uniformity, durability and compliance with technical requirements of the road surface, which is one of the important measures to ensure the quality of road engineering;

[0003] The traditional asphalt pavement paving temperature measuring mechanism usually consists of only a temperature sensor and a data display system. The temperature sensor is installed on the paving equipment to monitor the temperature of the asphalt mixture in real time and transmit the measured data to the display system, so that the operator can view the temperature of the asphalt on the display system immediately;

[0004] However, the structure of the traditional asphalt pavement paving temperature measuring mechanism is relatively single. Usually, when measuring, there is a certain distance between the measuring device and the asphalt pavement, and the measured temperature is also affected by the external ambient temperature. Moreover, due to the unevenness of the road surface, the height of the measuring device from the ground will also change accordingly. Therefore, there will be a certain error in the measured temperature. For this reason, a temperature measuring mechanism for asphalt pavement paving is proposed to solve the above problems. Summary of the Utility Model

[0031] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Refer to Figures 1-3 , an embodiment provided by the present invention: a measuring mechanism for the paving temperature of an asphalt pavement, including a paving machine body 1 and a measuring device 20. A support frame 2 is fixedly connected to the top of the paving machine body 1. A first motor 3 is fixedly connected to one side of the support frame 2. The output end of the first motor 3 is fixedly connected to a driving wheel 4. The driving wheel 4 is rotatably connected to the top of the paving machine body 1. A support seat 5 is fixedly connected to the top of the paving machine body 1. The outer wall of the support seat 5 is rotatably connected to a driven wheel 6. A synchronous belt 7 is arranged between the driven wheel 6 and the driving wheel 4. The bottom end of the driven wheel 6 is fixedly connected to a hollow column 8. The hollow column 8 is rotatably connected inside the paving machine body 1. A cylinder 9 is fixedly connected to the top of the support seat 5. The output end of the cylinder 9 is rotatably connected to a driving column 10. The driving column 10 is slidably connected inside the support seat 5 and the paving machine body 1. A sliding column 12 is slidably connected inside the hollow column 8. A connecting component is arranged on the outer wall of the driving column 10. The connecting component is used to connect the driving column 10 and the sliding column 12. The connecting component includes a connecting column 11. One end of the connecting column 11 is fixedly connected to the outer wall of the driving column 10, and the other end of the connecting column 11 is fixedly connected to the outer wall of the sliding column 12.

[0033] Specifically, during the process of asphalt paving, when there are changes between the measuring device and the asphalt pavement, the output end of the cylinder 9 can be used to precisely push the driving column 10 to move inside the support seat 5 and the paving machine body 1. The driving column 10 transmits force through the connecting column 11 connected to its outer wall, causing the connecting column 11 to drive the sliding column 12 connected to one end to slide inside the hollow column 8. Then, through the linkage between the sliding column 12 and the driving column 10, the support frame 13 connected to the bottom end is driven to move up and down, thereby precisely adjusting the height between the measuring device 20 and the ground. At the same time, the output end of the first motor 3 drives the driving wheel 4 to rotate. The driving wheel 4 drives the driven wheel 6 to rotate synchronously on the outer wall of the support seat 5 through the synchronous belt 7 connected to its outer wall. The movement of the driven wheel 6 causes the hollow column 8 connected to the bottom end to rotate. The hollow column 8 transmits power to the sliding column 12 inside, and then drives the connecting column 11 and the driving column 10 to rotate, so that the support frame 13 and the measuring device 20 rotate accordingly, thereby realizing the adjustment of the measuring height and position.

[0034] Refer to Figure 3 and Figure 4, both the sliding column 12 and the bottom end of the driving column 10 are fixedly connected with a support frame 13. A second motor 14 is fixedly connected inside the support frame 13. The output end of the second motor 14 is fixedly connected with a first rotating column 15. One side of the first connecting rod 16 is internally rotatably connected with a rotating shaft 17. One end of the rotating shaft 17 is fixedly connected with a sphere 18.

[0035] Specifically, when temperature measurement is required on a non-vertical surface, first use the second motor 14 to drive the first rotating column 15 to rotate inside the support frame 13. This action causes the first connecting rod 16 to rotate accordingly. The first connecting rod 16 transmits force through the rotating shaft 17, resulting in the rotation of the sphere 18 connected to one end of it, achieving the effect of motion transmission.

[0036] Refer to Figure 3 and Figure 4 , a support column 19 is fixedly connected to the outer wall of the sphere 18. One end of the support column 19 is connected to the measuring device 20. A third motor 21 is fixedly connected to one side of the support frame 13. The output end of the third motor 21 is fixedly connected with a second rotating column 22. The second rotating column 22 is rotatably connected inside the support frame 13. A second connecting rod 23 is fixedly connected to the outer wall of the second rotating column 22. The outer wall of the support column 19 is rotatably connected to the inside of one side of the second connecting rod 23.

[0037] Specifically, the movement of the sphere 18 drives the support column 19 connected to the outer wall to rotate inside the second connecting rod 23, thereby causing the support column 19 to drive the connected measuring device 20 to make the required angle adjustment. And through the output of the third motor 21, the second rotating column 22 is driven to rotate inside the support frame 13. The second rotating column 22 rotates through the second connecting rod 23 connected to the outer wall. The movement of the second connecting rod 23 affects the position of the internal support column 19, causing the movement of the support column 19 to cause the rotation of the sphere 18 again. The sphere 18 affects the position of the first connecting rod 16 through the rotating shaft 17. Finally, through the connecting column 11 and the driving column 10, the measuring device 20 can be precisely adjusted at different angles.

[0038] Working principle: When it is necessary to adjust the measuring height and position of the measuring device 20, first, the output end of the cylinder 9 pushes the driving column 10 to move inside the support base 5 and the paving machine body 1. The driving column 10 drives the connecting column 11 connected to its outer wall to move under force. The connecting column 11 drives the sliding column 12 connected to one end to slide inside the hollow column 8 under force. Then, the support frame 13 connected to the bottom end is driven to move up and down by the sliding column 12 and the driving column 10, so as to adjust the height between the measuring device 20 and the ground. At the same time, the output end of the first motor 3 can drive the driving wheel 4 to rotate. The driving wheel 4 drives the driven wheel 6 to rotate on the outer wall of the support base 5 through the synchronous belt 7 connected to its outer wall. The driven wheel 6 drives the hollow column 8 connected to the bottom end to rotate under force. The hollow column 8 drives the sliding column 12 inside to rotate under force. The sliding column 12 drives the connecting column 11 and the driving column 10 to rotate, so that the support frame 13 and the measuring device 20 rotate, thus achieving the effect of adjusting the measuring height and position. When it is necessary to adjust the measuring angle of the measuring device 20, the second motor 14 can drive the first rotating column 15 to rotate inside the support frame 13. The first rotating column 15 drives the first connecting rod 16 connected to its outer wall to rotate under force. The first connecting rod 16 drives the rotating shaft 17 to rotate under force. The rotating shaft 17 drives the sphere 18 connected to one end to rotate under force. The sphere 18 drives the support column 19 connected to its outer wall to rotate inside the second connecting rod 23, so that the support column 19 drives the measuring device 20 connected to one end to move. At the same time, the output end of the third motor 21 can drive the second rotating column 22 to rotate inside the support frame 13. The second rotating column 22 drives the second connecting rod 23 connected to its outer wall to rotate under force. The second connecting rod 23 drives the support column 19 inside to move under force. The support column 19 drives the sphere 18 to rotate under force. The sphere 18 drives the rotating shaft 17 to rotate inside the first connecting rod 16, so that the support column 19 drives the measuring device 20 to move at different angles, thus achieving the effect of adjusting the measuring angle.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
