Description

Scraper equipment for asphalt ductility instrument Technical Field The application relates to the technical field of asphalt ductility detection, in particular to scraper equipment for an asphalt ductility meter. Background The basic process of the measurement is that firstly, a melted sample is poured into a special mould, cooled at room temperature, then put into a water bath kept at a test temperature for cooling, the sample higher than the mould is scraped by a hot knife, the mould is put back into the water bath again, and then the mould is moved into a ductility meter after a certain time, and the bitumen test piece is stretched to the length of breaking at a certain speed under a certain temperature, namely the ductility of the bitumen test piece. The existing asphalt ductility detection die needs to scrape redundant asphalt, and a hot scraper needs to be clung to the upper end face of the die when scraping, so that the surface of an asphalt test piece is smooth. Structural design of prior art mainly adopts the manual work mode to repair the pitch surface, because the hot scraper has certain temperature, can scald the hand when the workman snatches, has the potential safety hazard, and the efficiency of repairing is lower, consequently remains to improve. Disclosure of utility model In order to facilitate trimming of asphalt on a die, the application provides scraper equipment for an asphalt ductility apparatus. The scraper equipment for the asphalt ductility instrument provided by the application adopts the following technical scheme: The scraper device for the asphalt ductility apparatus comprises a supporting seat, a positioning assembly, a lifting assembly and a scraping assembly, wherein the supporting seat is used for placing a die, the positioning assembly is arranged on the supporting seat and is close to two ends of the die, and the positioning assembly is used for compacting the die; The scraper comprises a supporting seat, a lifting assembly, a scraping assembly and a scraping main body, wherein the lifting assembly is arranged on the supporting seat, the scraping assembly is connected with the lifting assembly, the lifting assembly is used for controlling the scraping assembly to move up and down, the scraping assembly comprises a linear air cylinder, a heating plate and a scraper main body, the heating plate is connected to a piston rod of the linear air cylinder, the scraper main body is detachably connected to the heating plate, the scraper main body is used for scraping asphalt on a die, and the linear air cylinder is used for controlling the scraper main body to move horizontally. Through adopting above-mentioned technical scheme, when needs strike off pitch, the staff steadily places the mould that has pitch on the supporting seat, utilizes locating component to compress tightly the mould on the supporting seat afterwards, realizes the fixed of mould. And then, the vertical height of the scraping component from the supporting seat is adjusted by utilizing the lifting component, so that the cutting surface of the scraper main body is tightly attached to the upper end surface of the die. After the proper position is adjusted, the scraper main body is controlled by the linear cylinder to move along the horizontal direction, so that redundant asphalt of the die is scraped, and the surface smoothness of the die is ensured.
