[0022] The embodiments of the utility model will be described in detail below with reference to the drawings, and the embodiments are implemented on the premise of the technical scheme of the utility model, and detailed implementation modes and specific working processes are given, but the protection scope of the utility model is not limited to the following embodiments.

[0023] As Figures 1-5 The utility model discloses a wireless transmission digital display type temperature measurable rut plate mould which comprises a bottom plate 1, a fixed shaft 2 vertically arranged on the bottom plate 1, two long side plates 3 and two short side plates 4 movably connected to the fixed shaft 2, and plug-in holes 5 matched with the fixed shaft 2 arranged at the bottom of the long side plates 3 and the short side plates 4. Normally, the height of the long side plates 3 and the short side plates 4 is 50mm, two plug-in holes 5 are arranged on each long side plate 3 and short side plate 4, the plug-in holes 5 on each long side plate 3 and short side plate 4 are located at the three equal points of the side length, and the height of each plug-in hole 5 is 1 / 6~1 / 5 of the height of the long side plate 3 / short side plate 4. In the embodiment, the inner diameter of the plug-in hole 5 is 3mm, and the height is 8mm. The long side plates 3 and the short side plates 4 are staggered and connected to form a rectangular structure. Specifically, the long side plates 3 are arranged at the two ends of the short side plates 4, a pair of threaded holes 6 is arranged at the left and right ends of the short side plates 4, and a fixing bolt 7 is arranged in the threaded hole 6. Further, a heat insulation handle 8 is arranged on the outer wall of the long side plate 3 for convenient lifting. The surface of the heat insulation handle 8 is coated with a heat insulation coating 12, and a silica gel temperature insulation sleeve is nested. After the rut plate is formed, the connection between the long side plates 3, the short side plates 4 and the bottom plate 1 can be conveniently removed, and rapid demolding is realized.

[0024] ​​In order to reduce heat loss in the process of forming asphalt mixture rutting plate test piece, an insulating layer 9 is arranged on the inner wall of the open container formed by the long side plate 3, the short side plate 4 and the bottom plate 1. In this embodiment, the insulating layer 9 is coated by nano insulating coating with new generation of insulating factor technology, with a heat preservation rate of ≥90%, low cost, long service life and simple construction. In order to monitor and display the temperature in real time during the forming process of the rutting plate test piece, a first clamping groove and a second clamping groove are arranged on the outer wall of the long side plate 3 and the short side plate 4, both of which are groove structures. A high-temperature-resistant button cell 10 is installed in the first clamping groove, and a temperature display 11 is installed in the second clamping groove. A wireless temperature sensor 12 is installed on the inner wall of the long side plate 3 and the short side plate 4 (the sensor can not be coated with an insulating layer). In this embodiment, four wireless temperature sensors 12 are installed on each long side plate 3 / short side plate 4, which are arranged in two columns, and each column has two, which are arranged above the plug-in hole 5 and within the range of 20mm below the top and 10mm above the bottom of the long side plate 3 / short side plate 4. The range of each wireless temperature sensor 12 is -10℃~300℃, and the accuracy is 0.1℃. The above-mentioned high-temperature-resistant button cell 10 is electrically connected with the wireless temperature sensor 12 for power supply of the wireless temperature sensor 12. The wireless temperature sensor 12 and the temperature display 11 are communicatively connected, and can display the temperature in real time; at the same time, the wireless temperature sensor 12 is also wirelessly connected with the control center or the mobile phone APP for remote monitoring of temperature change.

[0025] Before the rutting plate test piece is formed, the mold should be placed in the oven for heating and insulation. In order to avoid damage to the temperature display 11 in a high-temperature environment, the temperature display 11 is first removed from the second clamping groove, then the mold is placed in the oven, the mold is heated to the specified temperature, and then the temperature display 11 is installed in the second clamping groove. In this embodiment, the temperature display 11 is fixed to the second clamping groove by magnetic attraction. In addition, the temperature display 11 can also be magnetically attracted to any position (<100m) outside the mold to observe the real-time temperature in the mold. Then, the mixed asphalt mixture is loaded into the mold and compacted, and the insulating layer 9 can effectively prevent the temperature of the asphalt mixture from decreasing. The 16 wireless temperature sensors 12 on the inner wall of the long side plate 3 and the short side plate 4 can monitor the temperature of the mixture in real time, and display the temperature value on the temperature display 11, or display the temperature value and temperature change curve in real time on the display screen of the control center or the mobile phone APP through wireless transmission, so as to ensure that the temperature of the asphalt mixture meets the rolling temperature. Under the condition that the temperature meets the requirements, the rutting plate mold containing the completed asphalt mixture is moved to the rolling forming machine by pulling the heat insulation handle 8 to start rolling. The rolling process ensures the quality of the asphalt mixture rutting plate test piece by monitoring the rolling temperature of the asphalt mixture in real time.
