The temperature measuring sensor 2 is connected to the connecting assembly, and the temperature measuring end of the temperature measuring sensor 2 is used to face the side of the guardrail 5 relative to the road.

[0033] Compared with the prior art, the truck wheel hub roadside temperature measuring device provided by the utility model has a temperature sensor 2 connected to the guardrail 5 through a connecting assembly, and the temperature measuring end of the temperature sensor 2 faces the side of the guardrail 5 relative to the road. In this way, when the truck passes through the road, the temperature sensor 2 can detect the wheel hub temperature of the truck, thereby avoiding the problem of lack of a device capable of detecting the wheel hub temperature of the truck on the market.

[0034] In this embodiment, the temperature measuring sensor 2 is an infrared temperature measuring sensor.

[0035] In some embodiments, the above-mentioned characteristic connection components can be used as follows Figure 4 See the structure shown. Figure 4 The connection assembly includes a first clamping member 11 and a second clamping member 12. The first clamping member 11 is located on one side of the guardrail 5.

The connection assembly and the guardrail 5 are connected by the second clamping member 12 and the first clamping member 11 to clamp the guardrail 5.

[0036] In some embodiments, the above-mentioned characteristic connection components can be used as follows Figure 1 , Figure 3 , Figure 4 and Figure 5 See the structure shown. Figure 1 , Figure 3 , Figure 4 and Figure 5 The connecting assembly also includes a first fixed rod 13, a second fixed rod 14, a limiting shaft 15, a sliding tube 16 and a protective box 17. The first fixed rod 13 is perpendicular to the road surface and is fixed on the first clamping member 11. The second fixed rod 14 is parallel to the first fixed rod 13 and is fixed on the second clamping member 12, and the top surface of the second fixed rod 14 is provided with a first threaded hole 141 whose axis is parallel to the second fixed rod 14.

The protective box 17 is fixed on the sliding tube 16, and the bottom surface of the protective box 17 is in contact with the top surface of the limiting shaft 15. Among them, the temperature sensor 2 is connected to the protective box 17. The protective box 17 can be slidably connected to the first fixed rod 13 through the sliding cooperation between the sliding tube 16 and the first fixed rod 13. Since the first fixed rod 13 is perpendicular to the road surface, the protective box 17 can slide close to or away from the road surface with the sliding tube 16. Since the first threaded hole 141 is parallel to the second fixed rod 14, that is, parallel to the first fixed rod 13, the limiting shaft 15 can be driven to rotate so that the limiting shaft 15 can be moved close to or away from the road surface. When the limiting shaft 15 is away from the road surface, the protective box 17 can be pushed to move in the direction away from the road surface; when the limiting shaft 15 is close to the road surface, the protective box 17 can also be moved in the direction close to the road surface. Since the temperature sensor 2 is connected to the protective box 17, the temperature sensor 2 can be adjusted to a suitable position away from the road surface by moving the protective box 17 close to or away from the road surface, so that the temperature sensor 2 can accurately measure the temperature within the appropriate area of ​​the truck wheel hub.

[0037] In some embodiments, see Figure 4The middle part of the protection box 17 has a protection channel 171, which runs through both ends of the protection box 17 along the width direction of the road, and the temperature sensor 2 is arranged in the protection channel 171. In this way, the protection box 17 can protect the temperature sensor 2 to a certain extent.

[0038] In some embodiments, the above-mentioned characteristic connection components can be used as follows Figure 1 , Figure 3 , Figure 4 and Figure 5 See the structure shown. Figure 1 , Figure 3 , Figure 4 and Figure 5 , the second fixing rod 14 is provided with a second threaded hole, and the connecting assembly further includes a first connecting bolt 18. The screw of the first connecting bolt 18 is inserted into the first fixing rod 13 and is threadedly connected to the second threaded hole, so that the head of the first connecting bolt 18 can press the first fixing rod 13 in the direction of the second fixing rod 14, so that the first clamping member 11 and the second clamping member 12 cooperate to clamp the guardrail 5. In this embodiment, the first fixing rod 13 and the first clamping member 11 are located on the side of the guardrail 5 facing the road, and the second fixing rod 14 and the second clamping member 12 are located on the side of the guardrail 5 facing away from the road. The axis of the second threaded hole is set along the width direction of the road.

[0039] In some embodiments, the above-mentioned characteristic connection components can be used as follows Figure 3 and Figure 5 See the structure shown. Figure 3 and Figure 5 , the connection assembly also includes a fixing member 19. The fixing member 19 is fixed on the bottom surface of the protection box 17, and the fixing member 19 is located on the side of the first fixing rod 13 facing the second fixing rod 14. The fixing member 19 has a spacing portion 191 spaced from the bottom surface of the protection box 17, and the spacing portion 191 has a notch 1911, and the notch 1911 penetrates the spacing portion 191 in the direction away from the first fixing rod 13. Among them, the limiting shaft 15 is slidably arranged in the notch 1911, and the side wall of the limiting shaft 15 has a pulling portion 151 protruding outward, and the pulling portion 151 is located between the protection box 17 and the spacing portion 191 and abuts against the spacing portion 191. When the limiting shaft 15 moves in the direction close to the road surface, the pulling portion 151 can pull the protection box 17 to move in the direction close to the road surface through the spacing portion 191. In this embodiment, if the first clamping member 11 and the second clamping member 12 release the guardrail 5, the limiting shaft 15 can exit the notch 1911.

[0040] In some embodiments, the above-mentioned characteristic connection components can be used as follows Figure 3 See the structure shown. Figure 3The connecting assembly further includes a plurality of drive shafts 20. The plurality of drive shafts 20 are evenly distributed around the limiting shaft 15, the drive shafts 20 are perpendicular to the limiting shaft 15 and one end of the drive shafts 20 is fixedly connected to the limiting shaft 15. It is convenient to drive the limiting shaft 15 to rotate by the drive shafts 20.

[0041] In some embodiments, see Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 , the temperature sensor 2 is rotatably connected to the protection box 17 and the axis of rotation is arranged along the direction of the guardrail 5. The truck wheel hub roadside temperature measuring device also includes a locking assembly, which includes a fixed shaft 31, two limit members 32, a first sleeve 33, a limit rod 34, a slider 35, a positioning tube 36 and a transfer shaft 37.

The two limit members 32 are respectively fixedly connected to the two ends of the fixed shaft 31, and the limit members 32 are fixedly connected to the temperature sensor 2. The first sleeve 33 is rotatably sleeved outside the fixed shaft 31. The limit rod 34 is arranged along the width direction of the road and one end is fixedly connected to the protection box 17. The slider 35 is slidably sleeved outside the limit rod 34, and the slider 35 is located below the first sleeve 33. The upper surface of the slider 35 is provided with a third threaded hole 351, and the axis center line of the third threaded hole 351 is perpendicular to the road surface. The positioning tube 36 is inserted into the third threaded hole 351 and is provided with a second external thread that is threadedly connected to the third threaded hole 351. The intermediate shaft 37 is slidably inserted into the positioning tube 36 and is fixedly connected to the first sleeve 33. The first sleeve 33 is rotatably arranged on the temperature sensor 2 after passing through the fixed shaft 31 and the stopper 32. When the positioning tube 36 is disconnected from the threaded connection with the slider 35, the temperature sensor 2 can be driven to rotate, thereby adjusting the angle between the temperature sensor 2 and the road surface until the temperature sensor 2 can accurately measure the temperature within the appropriate area of ​​the truck wheel hub, and then the slider 35 is driven to slide and the first sleeve 33 is driven to rotate until the third threaded hole 351 is realigned with the positioning tube 36, and finally the positioning tube 36 is re-threadedly connected to the third threaded hole 351. Thereby, the rotation of the temperature sensor 2 is restricted, and at this time, the slider 35 cannot continue to slide. In this embodiment, the rotation axis direction of the temperature sensor 2, the length direction of the stopper rod 34, and the axis centerline direction of the third threaded hole 351 are perpendicular to each other, forming a triangular coordinate system.

[0042] In some embodiments, see Figure 1 , Figure 2 , Figure 8 , Fig. 9 and Fig.10The truck wheel hub roadside temperature measuring device also includes two docking components, which are respectively located on both sides of the temperature sensor 2 along the rotation axis direction of the temperature sensor 2. The docking components include a connecting shaft 41, a second sleeve 42, a fixed pipe 43, a connecting pipe 44, a second connecting bolt 45 and a connecting crankshaft 46. The connecting shaft 41 is arranged along the rotation axis of the temperature sensor 2 and one end is fixedly connected to the temperature sensor 2. The second sleeve 42 is rotatably sleeved on the connecting shaft 41. The fixed pipe 43 is parallel to the limit rod 34 and one end is fixedly connected to the protection box 17. The fixed pipe 43 is provided with an internal thread. The connecting pipe 44 is coaxially arranged with the fixed pipe 43 and fits with the end face of the fixed pipe 43 away from the protection box 17. The screw of the second connecting bolt 45 is inserted into the connecting pipe 44 and the fixed pipe 43, and the screw of the second connecting bolt 45 is threadedly connected to the internal thread in the fixed pipe 43. The two ends of the connecting crankshaft 46 are respectively fixedly connected to the connecting pipe 44 and the second sleeve 42. The connecting tube 44 is fixedly connected to the protection box 17 by threaded connection between the screw of the second connecting bolt 45 and the internal thread in the fixing tube 43, and the second sleeve 42 is fixedly connected to the connecting tube 44 by connecting the crankshaft 46, that is, the second sleeve 42 is fixedly connected to the protection box 17. In this way, the rotational connection between the temperature sensor 2 and the protection box 17 is indirectly realized by the rotational cooperation between the second sleeve 42 and the connecting shaft 41. After the threaded connection between the two second connecting bolts 45 and the two fixing tubes 43 is disconnected, and then the slider 35 is driven to slide away from the limit rod 34, the temperature sensor 2 can be taken out of the protection box 17 for maintenance, calibration, etc.

[0043] In some embodiments, see Figure 2 The two ends of the first sleeve 33 are respectively in contact with the two limit members 32, thereby limiting the movement of the temperature sensor 2 along the direction of its rotation axis.
