Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, "multiple" means two or more, and "several" means one or more, unless otherwise clearly and specifically defined.

[0025] Please also read Figure 1 , the temperature monitoring device provided by the utility model is now described. The temperature monitoring device includes a base assembly, a slider 2, a driving assembly, a connector 4 and a temperature sensor 5. The base assembly is located on the ground on one side of the width direction of the prefabricated box girder. The slider 2 is slidably connected to the base assembly along the length direction of the prefabricated box girder. The driving assembly is used to drive the slider 2 to slide. The connector 4 is connected to the slider 2. There is at least one temperature sensor 5, and the temperature sensor 5 is fixed on the connector 4.

[0026] Compared with the prior art, the temperature monitoring device provided by the utility model is characterized in that the driving component drives the slider 2 to slide along the length direction of the prefabricated box girder, and the connecting piece 4 connected to the slider 2 drives the temperature sensor 5 to slide along the length direction of the prefabricated box girder, so that the temperature sensor 5 can monitor the temperature at multiple points on the moving path, thereby avoiding the problem that the temperature can only be monitored at a few points around the prefabricated box girder, resulting in incomplete data being obtained.

[0027] In some embodiments, the above-mentioned characteristic connecting member 4 can be adopted as follows Figure 1 See the structure shown. Figure 1The connector 4 is a U-shaped structure, and has a first connector 41, a second connector 42, and a third connector 43. The first connector 41 is located above the prefabricated box girder, and the second connector 42 and the third connector 43 are located on both sides of the width direction of the prefabricated box girder, respectively. There are three temperature sensors 5, and the three temperature sensors 5 are respectively fixed on the surfaces of the first connector 41, the second connector 42, and the third connector 43 facing the prefabricated box girder. In the process of the connector 4 moving with the slider 2, the three temperature sensors 5 can monitor more points, thereby further avoiding the problem that only the temperature of several points around the prefabricated box girder can be monitored, resulting in incomplete data.

[0028] In some embodiments, the connector 4 is detachably connected to the slider 2. Since the device is relatively large, the connector 4 and the slider 2 can be disconnected when the device is transported, so that the device can be transported in two parts, thereby reducing the difficulty of transportation.

[0029] In some embodiments, see Figure 1 and Figure 2 , the second connection part 42 and the slider 2 are located on the same side of the prefabricated box beam, and the temperature monitoring device also includes a connection block 6 and a positioning shaft 7. The connection block 6 is located on the slider 2, and the second connection part 42 is fixed on the connection block 6. There are multiple positioning shafts 7, and the positioning shafts 7 are vertically arranged. The positioning shafts 7 are slidably penetrated in the slider 2 and are fixedly connected to the connection block 6. The connection member 4 is connected to the slider 2 through the connection block 6 and the positioning shaft 7. When the multiple positioning shafts 7 slide out of the slider 2, the connection between the connection member 4 and the slider 2 is disconnected.

[0030] In some embodiments, see Figure 1 The temperature monitoring device further includes a rolling wheel 8. The rolling wheel 8 is disposed at the bottom end of the third connecting portion 43 and abuts against the ground. When the connecting member 4 moves with the slider 2, the rolling wheel 8 rolls along the length direction of the prefabricated box beam. The support of the rolling wheel 8 can prevent the device from tipping toward the third connecting portion 43 under the action of external force.

[0031] In some embodiments, the above-mentioned characteristic base assembly can be used as follows Figure 1 See the structure shown. Figure 1 The base assembly includes two fixed piers 11 and a guide shaft 12. The two fixed piers 11 are arranged at intervals along the sliding direction of the slider 2. There is at least one guide shaft 12, which is located between the two fixed piers 11. The guide shaft 12 is arranged along the sliding direction of the slider 2, and the two ends of the guide shaft 12 are respectively fixedly connected to the two fixed piers 11. The slider 2 is slidably sleeved on the guide shaft 12. The fixed pier 11 is placed on the ground, and the sliding connection between the slider 2 and the guide shaft 12 is realized by the sliding cooperation between the slider 2 and the guide shaft 12.

[0032] In some embodiments, see Figure 1 , the slider 2 is provided with a threaded hole, and the driving assembly includes a driving screw 31 and a driving motor 32. The driving screw 31 is parallel to the guide shaft 12, and the driving screw 31 is rotationally connected to both fixed piers 11, and the driving screw 31 passes through the threaded hole and is threadedly connected to the threaded hole. The driving motor 32 is fixedly connected to one of the fixed piers 11, and the output shaft of the driving motor 32 is connected to one end of the driving screw 31. The output shaft of the driving motor 32 drives the driving screw 31 to rotate, thereby causing the slider 2 threadedly connected to the driving screw 31 to slide. In this embodiment, a bearing seat 10 is fixedly provided on the fixed pier 11, and the driving screw 31 is rotationally connected to the fixed pier 11 through the bearing seat 10.

[0033] In some embodiments, the above-mentioned characteristic base assembly can be used as follows Figure 1 See the structure shown. Figure 1 The base assembly further includes a fixing plate 13. The fixing plate 13 is horizontally arranged and fixedly connected to one of the fixing piers 11. The driving motor 32 is fixedly arranged on the fixing plate 13, so as to realize the fixed connection between the driving motor 32 and one of the fixing piers 11.

[0034] In some embodiments, see Figure 1 , the second connection part 42 and the third connection part 43 are used to be fixedly provided with a lifting assembly on the surface away from the prefabricated box beam, and the lifting assembly includes a lifting block 91 and two lifting shafts 92. The lifting block 91 is fixedly connected to the second connection part 42 or the third connection part 43. The two lifting shafts 92 are arranged at intervals along the length direction of the prefabricated box beam, and the lifting shafts 92 are arranged along the width direction of the prefabricated box beam and are fixedly connected to the lifting block 91. When the positioning shaft 7 is pulled out from the slider 2 or the positioning shaft 7 is slid into the slider 2, two operators can operate it. The two operators stand near the two lifting assemblies respectively, and the operators hold the two lifting shafts 92 in the nearby lifting assemblies. In this way, the two operators can control the lifting and lowering of the connecting member 4, so that the positioning shaft 7 can be pulled out from the slider 2 or the positioning shaft 7 can be slid into the slider 2.

[0035] Based on the same inventive concept, an embodiment of the present application also provides a steam curing system for a prefabricated box girder, which is provided with the above-mentioned temperature monitoring device, so as to avoid the problem that only the temperature of a few points around the prefabricated box girder can be monitored, resulting in incomplete data obtained.
