The invention relates to the technical field of municipal road maintenance instruments, and discloses a road cone recycling and placing system. The system comprises a pulley bracket, wherein one sideof the upper surface of the pulley bracket is fixedly connected with the bottom of a warehouse-out module sliding rail, the upper surface of the warehouse-out module sliding rail is in sliding connection with one sides of roller bearings, the middle part of the roller bearings are fixedly connected with the top of one side of a baffle through bolts, and one end of the bottom of the pulley bracketis fixedly connected with the bottom of a triangular bracket I. According to the road cone recycling and placing system, a road cone is grabbed from a stepping mechanism workbench through a road conegrabbing manipulator, a road cone centralizing mechanism is used for centralizing a horizontal side reverse road cone, a road cone shifting mechanism is used for shifting a road cone in the recyclingprocess, a road cone can be automatically placed, and the problems that the road cone is carried and placed by manual traditionally, the working task is heavy, a large potential safety hazard is caused by constructing on a highway, and the road cone placing speed is slow are solved.
