Description

Technical Field

[0001] This utility model relates to the field of paint transportation technology, and in particular to a leak-proof device for transporting hot-melt road marking paint. Background Technology

[0002] Hot-melt reflective road marking paint is mainly used on Class 2 and above highways and expressways. The thickness of the marking coating made with this paint is (1.0~2.5) mm. The paint contains reflective glass beads, which are sprinkled on the surface during the marking process. This type of marking has good nighttime reflective performance and a long service life. After the paint is produced, it needs to be packaged and transported to the destination for road marking. Basically, the transportation vehicle is a material barrel. The paint is packaged into the material barrel and loaded onto the vehicle for transportation. Since the material barrel is cylindrical, it is easy to roll during transportation. Therefore, it needs to be restrained to ensure the safety and stability of the material barrel during transportation and to prevent the material barrel from rolling and breaking, causing the paint to spill out.

[0003] CN214165779U discloses a leak-proof device for transporting hot-melt road marking paint, including a base. The top of the base has two placement slots, and both ends of the placement slots are equipped with clamping mechanisms. The top of the two placement slots is equipped with a pressing mechanism. The pressing mechanism includes a horizontal plate, and both ends of the horizontal plate are fixedly equipped with L-shaped plates. The bottom of the L-shaped plates is equipped with a limiting mechanism. Both sides of the horizontal plate are slidably connected with a first guide rod. The bottom end of the first guide rod is fixedly equipped with a V-shaped plate. One end of the V-shaped plate is equipped with a sliding mechanism. A positioning mechanism is fixedly provided between the two V-shaped plates.

[0004] In use, existing devices can only transport collection buckets containing hot-melt road marking paint in a fixed position. After the paint arrives at the designated location, workers need to use a crane to unload it, which is inefficient. In addition, paint residue is easily left on the inner wall of the collection bucket, making it difficult to clean later. Therefore, we propose a leak-proof device for transporting hot-melt road marking paint. Utility Model Content
