[0024] The invention is used in the following ways: It has a reasonable and simple structure, low production cost, and convenient installation. In use, the angle of the spray pipe 315 in the adjustable side spraying mechanism 3 is first adjusted as needed. Specifically, the motor 319 is started to drive the spline shaft 320 to rotate. The rotation of the spline shaft 320 drives the worm gear 321 to rotate through the spline sleeve 322. The rotation of the worm gear 321 then drives the rotating seat 316 and the spray pipe 315 to rotate to the required angle through the worm wheel 317. When the spray pipe 315 rotates upwards (e.g....), the angle of the spray pipe 315 is adjusted accordingly. Figure 2 As shown), this facilitates access to the inside of the box girder for water spraying operations. Simultaneously, the adjustable top spraying mechanism 5 allows for simultaneous water spraying of the inner walls around the box girder, thus improving the curing effect inside the box girder and reducing the workload of workers. When the spray pipe 315 rotates downwards (as shown...), Figure 3 As shown), the external surface of the box girder can be sprayed with water through nozzles 324 and 38, thereby improving the curing effect of the box girder and enhancing the practicality of the curing trolley. This further reduces the workload of workers. The adjustable side spraying mechanism 3 has nozzles 324 and 38 on both sides, ensuring that water can be sprayed along the edges of the box girder. In addition, in conjunction with motors 31 and 51, the distance between the nozzles on the left and right sides can be adjusted, ensuring that the box girder can absorb water more fully while the curing trolley is in motion, thus improving the curing effect. When spraying water, water pumps 32 and 52 are started first, and water pump 3 is started here. 2. Water in the water storage chamber 4 can be transported to the connecting hole 311 through the fixed pipe 33. Water in the connecting hole 311 enters the inner cavity 39 through the fixed pipe 310. Part of the water in the inner cavity 39 is sprayed directly through the nozzle 38 to water the inner bottom or outer top surface of the box girder. Another part of the water in the inner cavity 39 is transported to the spray pipe 315 through the connecting pipe 318 and then sprayed through the nozzle 324 to water the inner and outer sides of the box girder. When the water pump 52 is started, water in the water storage chamber 4 can be transported to the spray pipe 56 through the fixed pipe 57 and the water supply hole 58. Water in the spray pipe 56 is sprayed through the nozzle 55 to water the inner top surface of the box girder.
