Limiting mechanism of travelling crane

The utility model provides a limiting mechanism of a travelling crane, and belongs to the technical field of machinery. The problem of poor stability in the prior art is solved. The limiting mechanism of the travelling crane comprises the sensor, the limiting plate and the damping reset structure, the sensor is fixedly connected to the crane body, the limiting plate is movably connected to the guide rail and right faces the sensor, the damping reset structure is located between the limiting plate and the guide rail, and the sensor can stably touch the limiting plate under the action of the damping reset structure. And after the vehicle body is moved away from the limiting plate, the limiting plate can be reset under the action of the damping reset structure. The limiting mechanism of the travelling crane is high in stability. 本实用新型提供了一种行车的限位机构，属于机械技术领域。它解决了现有技术存在着稳定性差的问题。本行车的限位机构包括传感器、限位板和阻尼复位结构，上述传感器固连在车体上，上述限位板活动连接在导轨上且限位板与传感器正对，上述阻尼复位结构位于限位板与导轨之间，在阻尼复位结构的作用下传感器能稳定触碰限位板，并能使限位板摆动避让车体，当车体由限位板处移开后在上述阻尼复位结构的作用下
