Abstract
Description
Technical Field
[0001] The present application relates to the field of asphalt construction, and in particular to a temperature detection mechanism for asphalt mixture leaving the factory. Background Art
[0002] Asphalt mixture is a composite material, mainly composed of asphalt, coarse aggregate, fine aggregate, mineral powder, and some also have polymers and wood cellulose. These materials of different quality and quantity are mixed to form different structures and have different mechanical properties. The aggregate needs to be heated to a higher temperature when mixing the asphalt mixture. The temperature of the asphalt mixture needs to be tested when it leaves the factory. The temperature of the mixture has a direct impact on the construction effect. If the temperature is too high or too low, it may cause the mixture to deform, poorly bond or cool too quickly during the construction process. The factory inspection and recording of temperature is to ensure the quality and performance of the mixture and meet construction requirements. At the same time, understanding the viscosity and fluidity of the mixture can help adjust the temperature control during the mixing process to ensure the uniformity and stability of the mixture. The temperature of the mixture can be adjusted according to the detected temperature to obtain better construction results.
[0003] The temperature detection of asphalt mixture is usually measured by an inserted asphalt thermometer, which can provide accurate temperature data. During construction, it is necessary to detect the temperature of the asphalt in all asphalt mixture vehicles leaving the site to prevent asphalt concrete with unqualified temperature from entering the paving site. Therefore, it is necessary to detect the temperature of the asphalt mixture in the transport vehicle at a very high frequency. In the existing process, when the asphalt transport vehicle stops at the scale, the operator carries a temperature measuring instrument and climbs up the transport vehicle through a ladder to detect the surface temperature of the asphalt concrete leaving the site. However, due to the high height of the transport vehicle, the operation is extremely inconvenient, which can easily cause safety and quality accidents. The operator frequently gets on and off the vehicle to detect the asphalt, which is very likely to cause unsafe accidents of falling from heights. The temperature of the asphalt mixture is very high and has an unpleasant smell, which can easily cause burns or even dizziness to the operator. At the same time, the weighing efficiency is not high. In the existing asphalt mixing station, the transport vehicles that are not covered with quilts often queue up for a long time to detect the temperature and weigh, which may cause the asphalt mixture to cool down before leaving the site. It can be seen that the existing technology needs to be further improved and improved. Utility Model Content

When the sensing component 20 detects that the asphalt transport vehicle has arrived at the designed position, it transmits a signal to the control component. The control component controls the movement of the moving component on the crossbeam 11 to drive the temperature measurement of the asphalt mixture on the opposite side of the temperature measuring component 21 connected thereto. There is no need for operators to climb up and down the transport vehicle with the help of ladders for temperature detection, and data can be recorded only in the weighing room. The entire temperature measurement process is intelligent and coherent, with a high safety factor, which is conducive to improving the efficiency of weighing and factory delivery.
[0034] The specific implementation mechanism of the mobile component can be found in Figure 2 In this embodiment, the moving component includes a first moving beam 30 perpendicular to the ground, the cross beam 11 is connected to the first moving seat 31, the first moving seat 31 is provided with two opposite first sliders 310, and two opposite first slide rails 300 are provided on both sides of the first moving beam 30, and the first slide rails 300 are matched and connected with the first slider 310; the first moving seat 31 is provided with a first motor 32, and the end of the first motor 32 is provided with a first gear, the first moving beam 30 is provided with a first rack portion 301 along its length direction, and the first gear is meshed and connected with the first rack portion 301, and the temperature measuring component 21 is provided at the end of the first moving beam 30, and the operation of the first motor 32 can make the first moving beam 30 move relative to the first moving seat 31, so that the temperature measuring component 21 is vertically close to or away from the asphalt transport vehicle.
[0035] As a preferred embodiment of the present embodiment, a second movable seat 41 is provided on the top surface of the cross beam 11, and two opposite second sliders 410 are provided on the top surface of the second movable seat 41.

The second movable beam 40 is provided with a second rack portion 401 extending along its length direction, and the second gear 420 is meshingly connected with the second rack portion 401. The first movable seat 31 is arranged at the end of the second movable beam 40. The operation of the second motor 42 can move the second movable beam 40, so that the temperature measuring component 21 moves along the length direction of the asphalt transport truck.
[0036] Furthermore, a third slide rail 110 is provided on the top surface of the crossbeam 11, and a third slider 411 is provided on the bottom surface of the second movable seat 41, and the third slide rail 110 and the third slider 411 are cooperatively connected; the second movable seat 41 is also provided with a third motor 43, and a third gear 430 is provided at the end of the third motor 43.

For example, the temperature of a transport vehicle can be measured three times at different positions or different vehicles can be measured once at different positions, thereby improving the measurement accuracy and preventing the phenomenon that the temperature of the asphalt mixture at a certain position is qualified while the temperature of other positions is unqualified.
[0038] At the same time, in order to observe the color of the asphalt mixture in the transport vehicle and prevent inferior materials such as white materials from leaving the factory, in this embodiment, refer to Figure 1 The crossbeam 11 is provided with a camera 5 to observe the loading situation of the asphalt mixture in the asphalt transport vehicle.

The support rod 6 is arranged on both sides of the floor scale 7. The principle of laser beam detection is used. When the vehicle comes between the two photoelectric sensors, the light is blocked, thereby detecting that the vehicle has come to this position. This is a prior art. The support rod 6 is also provided with an indicator light 60 such as a traffic light. Compared with voice and ringing prompts, the indicator light 60 is more suitable for noisy asphalt mixing plants. When the photoelectric sensor detects that the asphalt transport vehicle has arrived at the designated position, the indicator light 60 lights up. The driver stops the car after seeing it, which is convenient for subsequent temperature detection.
[0042] The parts not described in the present invention can be realized by adopting or drawing on the existing technology.
