The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In order to reduce trolley's wheel and orbital friction when crossing curved for trolley crosses curved smooth and easy, improves the life of wheel, as shown in fig. 2-4, the utility model provides a guiding mechanism, including leading wheel axle 1, leading

wheel

2, 2 covers of leading wheel are established on leading wheel axle 1, and leading wheel 2 can be rotatory around the axis of leading wheel axle 1, and in this embodiment, leading wheel 2 is configured into: the side of the guide wheel 2 can abut against the vertical part of the track when the wheel passes a curve of the track.

In the embodiment, the guide mechanisms are arranged on the front side and the rear side of the wheels of the trolley, so that the wheels can play a role in the advancing or retreating process. By arranging the guide mechanism, when the wheel is bent excessively, the side surface of the guide wheel 2 of the guide mechanism is abutted against the vertical part of the track, and the centripetal force of a part of the crane trolley when the wheel is bent excessively is counteracted by the acting force between the guide wheel 2 and the vertical part of the track, so that the friction between the wheel and the horizontal part of the track is reduced, the abrasion of the wheel is reduced, and the service life of the wheel is prolonged; meanwhile, the guide wheel 2 can rotate along the axis of the guide wheel shaft 1, so that the trolley can smoothly run when the trolley is bent.

Further, in order to ensure that the guide wheel 2 flexibly rotates along the axis of the guide wheel shaft 1 and reduce the friction force between the guide wheel 2 and the guide wheel shaft 1, the guide mechanism further comprises a bearing 3, the bearing 3 is sleeved on the guide wheel shaft 1, and the guide wheel 2 is sleeved on the bearing 3.
