The utility model relates to the technical field of forging equipment, and provides a cone roller split mechanism and a ring rolling mill, the cone roller split mechanism comprises a rack, a rotating shaft, a connecting rod, a cone roller, a hydraulic nut and a fastener, the connecting rod penetrates through the rotating shaft; the conical roller and the hydraulic nut are oppositely arranged at the two ends of the connecting rod and are connected in a threaded screwing mode. The fastener is arranged on the hydraulic nut and used for limiting the stroke of the hydraulic nut. The conical roller and the hydraulic nut are arranged at the two ends of the connecting rod, so that the conical roller can be tensioned through the connecting rod by pressurizing the hydraulic nut, and the conical roller and the rotating shaft are fixed; meanwhile, the connecting rod is connected with the conical roller in a screwed mode through threads, the hydraulic nut serves as a pressurizing piece, the conical roller can be loosened after pressure relief, and therefore the conical roller can be disassembled conveniently, and the structure is simple; and the hydraulic nut of the structure is located on the outer side, overhauling and maintenance can be continued conveniently, and application convenience can be improved.

The invention relates to a drive control circuit and method for a steam turbine speed regulator. The drive control circuit comprises a direct-current power supply input unit and at least one drive branch. The direct-current power input unit comprises a live wire and a zero wire; the number of the driving branches is equal to that of the OPC electromagnetic valves, each driving branch comprises an intermediate relay K1 and a contactor KM1, one end of a coil of the intermediate relay K1 is electrically connected with the live wire, the other end of the coil of the intermediate relay K1 is electrically connected with the zero line, one end of a normally open contact of the intermediate relay K1 is electrically connected with the live wire, and the other end of the normally open contact of the intermediate relay K1 is electrically connected with the zero line. One end of a coil of the contactor KM1 is electrically connected with the other end of the normally open contact of the intermediate relay K1, and the other end of the coil of the contactor KM1 is electrically connected with the zero line. The contactor is driven by the intermediate relay, the intermediate relay K1 serves as a control stage, the coil power consumption is small, direct and safe driving can be achieved through a passive dry contact signal of a steam turbine speed regulator, and the problem that a large-current load impacts a precision controller is solved.

The application discloses a kind of road-electricity coupling system optimization scheduling method, device, equipment and program product.The method can be determined by according to traffic trip path decision model, traffic space-time distribution rule, fast charging demand space-time distribution rule and basic charging path time consumption data, and then constructs the day-to-day real-time path planning model considering new energy prediction error, to determine the target charging planning result of electric vehicle, road network real-time vehicle distribution result and new energy output scheduling information of grid side, finally based on road-electricity coupling collaborative optimization model, with distribution network operation cost and traffic network travel time cost as joint optimization target, with target charging planning result, road network real-time vehicle distribution result and new energy output scheduling information as constraint condition, determine road-electricity system scheduling result, to solve the impact problem of electric vehicle charging and driving on power grid and traffic network in the prior art, improve new energy utilization and road network traffic efficiency.

The utility model discloses a kind of plunger type swing cylinder with signal output function for concrete pump, it is related to concrete pump component field, and its technical scheme main point is: including cylinder and total plunger, oil inlet and signal port are equipped on the cylinder, the total plunger is arranged in cylinder and can be moved along cylinder axial direction, the total plunger is equipped with cavity in one end inside cylinder, effect is through the damping effect or elastic deformation of buffer component absorption kinetic energy, slow down the moving speed of total plunger, to realize buffering effect, avoid the impact problem caused by structural restriction of traditional piston type swing cylinder;And this swing cylinder is only set oil inlet and signal port, cancel the oil outlet of traditional piston type swing cylinder, avoid the back pressure interference of oil return structure with multiple oil ports, simultaneously sealed control to the hole moving path using sealing ring A, ensure that signal port is only in set position conduction, realized the double function of hydraulic signal stable feedback and buffering.
