[0028] like Figure 1-Figure 2 As shown, an auxiliary device for asphalt pavement construction provided by the utility model includes: a temperature sensor 10, a prompting device 30 and a moving seat 20.

[0029] The temperature sensor 10 is disposed at a preset depth in the asphalt 40. The prompt device 30 is detachably electrically connected to the temperature sensor 10, and the prompt device 30 is mounted on the moving seat 20.

[0030] It should be noted that, in actual applications, the temperature sensor 10 is buried in the asphalt, and the temperature sensor 10 may be located at a preset depth in the asphalt.

[0031] The prompt device 30 may be a display screen, a voice announcer, a color display, etc., which are not listed one by one in this embodiment.

[0032] The auxiliary device also includes a sensor connection line 52, a prompt connection line 51, and a plug 61 and a socket 62 that cooperate with each other. One end of the sensor connection line 52 can be electrically connected to the temperature sensor 10, and the other end of the sensor connection line 52 can be electrically connected to the plug 61; one end of the prompt connection line 51 can be electrically connected to the prompt device 30, and the other end of the prompt connection line 51 can be electrically connected to the socket 62. The socket 62 and the plug 61 are plugged and matched to realize a detachable electrical connection between the prompt device 30 and the temperature sensor 10. With this arrangement, the electrical connection between the prompt device 30 and the temperature sensor 10 is easy to disassemble and simple to reconnect.

[0033] During the asphalt pavement construction process, several temperature sensors 10 connected with sensor connection lines 52 are buried in the asphalt 40 in real time along the laying direction of the asphalt 40. The distance between two adjacent temperature sensors 10 is C, 10m≤C≤100m. Preferably, the distance between two adjacent temperature sensors 10 is 50m.

[0034] For example, three temperature sensors 10 are buried in real time: a first temperature sensor 10a, a second temperature sensor 10b, and a third temperature sensor 10c. The first temperature sensor 10a and the second temperature sensor are spaced 50m apart, and the second temperature sensor 10b and the third temperature sensor are spaced 50m apart. The temperature sensors 10 correspond to the sensor connection lines 52 one by one, the first temperature sensor 10a is connected to the first sensor connection line 52a, the second temperature sensor 10b is connected to the second sensor connection line 52b, and the third temperature sensor 10c is connected to the third sensor connection line 52c.

[0035] The first sensor connection line 52a and the prompt connection line 51 are electrically connected through the plug 61 and the socket 62, so that the prompt device 30 can obtain the temperature value of the asphalt sent from the first temperature sensor 10a in real time. Among them, the prompt device 30 can use digital display, voice playback, color display, etc. to allow the roller operator or construction personnel at the construction site to promptly know the real-time temperature value of the asphalt 40 in the area corresponding to the first temperature sensor 10a, so that the roller operator or construction personnel can understand that the operation is carried out under the appropriate asphalt temperature value, and even if the asphalt paving operation is carried out under relatively low weather temperature, the quality of the construction can be guaranteed.

[0036] Next, the second sensor connection line 52 b and the prompt connection line 51 are electrically connected through the plug 61 and the socket 62 ; finally, the third sensor connection line 52 c and the prompt connection line 51 are electrically connected through the plug 61 and the socket 62 .

[0037] To summarize, in this embodiment, the temperature sensor 10 buried in the asphalt 40 is electrically connected to the prompt device 30. The prompt device 30 can use digital display, voice playback, color display, etc. to allow the roller operator or construction personnel at the construction site to promptly know the real-time temperature value of the asphalt in the area corresponding to the temperature sensor 10, so that the roller operator or construction personnel can understand that the operation should be carried out under the appropriate asphalt temperature value, and even if the asphalt paving operation is carried out under relatively low weather temperatures, the quality of construction can be guaranteed.

[0038] According to some embodiments of the present invention, the lifting device includes a display screen.

[0039] In a specific example, the display screen can display the asphalt temperature value in real time. The display screen can be square or rectangular, with a length of L1, 0.4m≤L1≤1m, and a width of L2, 0.4m≤L2≤1m; or, the display screen is circular, with a diameter of d, 0.4m≤d≤1m. This setting ensures that the operators within a range of 50m to 100m can see the asphalt temperature value on the display screen as much as possible.

[0040] In practical applications, considering the cost and display effect, preferably, the display screen is square, and the length and width of the display screen are both 0.8 m.

[0041] Furthermore, the prompt device 30 also includes a rotating mechanism connected to the display screen. The rotating mechanism can be a gear set, which includes a driving gear and a driven gear, and the display screen is installed in the axial direction of the driven gear. The rotation of the driving gear drives the driven gear to rotate 360°, so that the display screen can rotate 360°. In this way, workers in various areas of the construction site can see the asphalt temperature value on the display screen as much as possible.

[0042] Of course, it is understandable that the rotating mechanism may also be other mechanisms, and this embodiment does not limit this.

[0043] According to some embodiments of the present invention, the prompting device 30 includes a voice announcer.

[0044] It should be noted that the voice announcer can announce the temperature value of the asphalt at each temperature difference interval, for example, at intervals of 2°C, 3°C, and 3.5°C. The temperature difference is not limited in this embodiment, and those skilled in the art can set it as needed.

[0045] According to some embodiments of the present invention, the prompt device 30 includes a color display light.

[0046] It should be noted that the color display lights may include red, green, and yellow. Red is the first temperature range value of asphalt, indicating that the operation cannot be performed at the current moment. Green is the second temperature range value of asphalt, indicating that the operation can be performed at the current moment. Yellow is the third temperature range value of asphalt, indicating that the operation is about to start at the current moment, prompting each operator to prepare for the operation.

[0047] Of course, it is understandable that the color display light may also include lights of other colors, and the red light, green light, and yellow light also represent different meanings. Those skilled in the art may adjust them according to actual conditions, and this embodiment does not limit this.

[0048] According to some embodiments of the present invention, the movable seat 20 includes a support member 22, and the support member 22 can be telescopic in the vertical direction.

[0049] It should be noted that the support member 22 can be an electric push rod, a gear rack assembly, a connecting rod assembly, etc., which are not listed one by one in this embodiment. The support member 22 can be retracted in the vertical direction, and the height of the prompt device 30 can be adjusted as needed, so that the operators in various areas of the construction site can know the asphalt temperature value as much as possible.

[0050] In a specific embodiment, Figure 1 As shown, the movable seat 20 includes a seat body 21, a support member 22, a wire rack 23 and a pulley 24. The support member 22 is connected to the seat body 21, and the support member 22 is an electric push rod. The wire rack 23 is connected to the telescopic member, and the extension direction of the wire rack 23 is perpendicular to the telescopic direction of the telescopic member. The wire rack 23 is used to support the prompt connection line 51, so that the electrical connection between the prompt connection line 51 and the sensor connection line 52 and the sensor connection line 52 are suspended to avoid contact with asphalt.

[0051] The pulley 24 is connected to the seat body 21, so that the movable seat 20 can be easily moved from one temperature sensor 10 to the next temperature sensor 10, reducing the labor intensity of the operators.
