Description

Road and bridge is with mark marking device Technical Field The invention belongs to the technical field of road construction, and particularly discloses a marking and scribing device for roads and bridges. Background The hot melt road marking paint has become the main material for road marking construction because of the advantages of quick drying, wear resistance, durability, excellent light reflection performance and the like. In construction, the granular paint is melted in a heating device and kept at a suitable working temperature (usually about 180-200 ℃) and then applied by a scribing machine. At present, a large number of small and medium-sized hot melting scribing machines or kettles are used, and the heating mode of the hot melting scribing machines or kettles generally adopts a portable liquefied petroleum gas (gas) tank combined with an open flame burner to directly heat the bottom of a metal tank. The traditional heating mode is simple and low in cost, but the following series of interrelated and serious technical defects are exposed in practical application, and the construction quality, efficiency and safety are directly affected. The problems of local overheating and coking and scaling of the tank bottom paint are prominent. The open flame directly and continuously burns the central area of the bottom of the charging bucket, so that the temperature of the local area is extremely easy to exceed the thermal decomposition threshold (about 220-230 ℃) of the paint. The paint at the bottom of the tank is heated by overheating for a long time, and organic components such as resin, additives and the like in the paint can be subjected to thermal aging, coking and even carbonization to form hard rice crust-like caking. The cokes not only can block a subsequent discharge hole and a filter screen, but also can be mixed into the molten paint as impurities, so that quality defects such as particles, uneven color and luster, early peeling and the like of the marked lines are caused, and when serious, the cokes are required to be manually cleaned by stopping the machine, so that the construction continuity is greatly influenced; The heat transfer mode of open fire heating is mainly based on bottom heat conduction, and the heat transfer to the upper part and the central area is seriously dependent on slow heat conduction and limited convection of the materials. This necessarily causes a large vertical temperature gradient in the tank, with the bottom overheated and the middle-upper temperature insufficient. The operator has to further increase the bottom fire or extend the heating time in order to bring the top coating to the melting temperature, which in turn exacerbates the bottom coking risk and creates a vicious circle. Meanwhile, a large amount of heat is dissipated through the tank wall and the top, so that the energy utilization rate is low, and the fuel consumption is high; Conventional cans are typically single-layered metal structures, and heat loss from the walls of the cans is severe in outdoor construction environments (especially winter or night). Once the heating is stopped or the fire is slightly reduced, the temperature of the paint is rapidly reduced, and the temperature is raised again to cause a new round of local overheating and coking. The severe temperature fluctuation causes unstable viscosity of the coating, directly influences thickness uniformity of the marking coating, the embedding rate of glass beads and adhesion force with a road surface, finally influences service life of the marking and night light reflecting effect, and in sum, the fundamental sign of the current hot-melt scribing machine based on direct heating of open gas flame is that an irreconcilable contradiction exists between the original and extensive heat source action mode and the required uniform, accurate and stable thermal management requirement of the coating. Although the prior art is improved by stirring, improving the pot shape and the like, the prior art cannot be radically innovated from the heat source transmission path and the heat preservation structure, and the three core pain points of coking, uneven and non-heat preservation cannot be simultaneously solved. Therefore, a brand new design of heating and heat insulation structure is needed to realize uniform, efficient transfer and controllable maintenance of heat from the root so as to meet the strict requirements of high-quality road marking construction. Disclosure of Invention The invention aims to solve the problems in the background art, and provides a marking and scribing device for roads and bridges, which comprises a moving vehicle, wherein a gas box is fixedly arranged above the moving vehicle, a glass bead storage box is fixedly arranged on the outer wall of one side of the gas box, a heating shell is fixedly arranged above one side, far away from the gas box, of the moving vehicle, a heating tank is fixedly arranged above the heating shell
