The invention discloses an antiskid chain scraper conveyor for conveying carbon blocks. The antiskid chain scraper conveyor comprises a support, a chain scraper installed on the support, a power device driving the chain scraper to move and four or more carbon block antiskid devices installed on the support. Each carbon block antiskid device comprises a portal frame composed of two vertical columns and a cross beam and a carbon block stop handle, wherein the two vertical columns of each portal frame are installed at the parts, on the two sides of the chain scraper, of the support, and the carbon block stop handle of each portal frame is installed in the middle of the right vertical face of the cross beam of the corresponding portal frame through a hinge shaft. According to the antiskid chain scraper conveyor for the carbon blocks, the problem that the carbon blocks skid vertically on the chain scraper in the conveying process is solved, the carbon blocks stopping skidding are conveyed to the top of the chain scraper along the chain scraper, and therefore normal conveying of the carbon blocks on the chain scraper can be realized; the workload and the cost for operation and maintenance of the chain scraper are lowered, and the conveying work efficiency of the carbon blocks is improved.
