The utility model provides a gear shifting clutch device matched with a railway engineering vehicle walking control system. The gear shifting clutch device comprises a transmission mechanism, an auxiliary piece and a correlation mechanism. The transmission mechanism is provided with an air cylinder, a piston rod, a sliding rod, a stirring rod, a shifting fork and a gear. The correlation mechanism is provided with a shaft. The gear is arranged on the shaft. The transmission mechanism is connected with the correlation mechanism through the gear and the shaft. The air cylinder is arranged above the sliding rod, and a high-low staggering arranging structure is formed. The piston rod is connected with the stirring rod. The upper end of the stirring rod is provided with a bearing and a guiding groove. The lower end of the stirring rod is connected with the sliding rod. The stirring fork is arranged on the sliding rod which is provided with the stirring fork. Balance of the stirring rod is controlled by matching of the bearing and the guiding groove, the gear blocking position is controlled by matching of the gear and the shaft, and then gear shifting clutching is achieved. According to the gear shifting clutch device, a gear shifting clutch mechanism of an up-down staggering structure is reasonably arranged in a limited space, middle transmission chains are reduced, and the gear shifting clutch device has the advantages of being simple in structure, compact in layout, reliable in operation and safe to operate.
