Track walking trolley assembly

The utility model discloses a track walking trolley assembly which comprises a walking trolley and a track. The synchronous belt extending in the extending direction of the track and the driving synchronous belt wheel in the walking trolley serve as a driving device for the walking trolley to move front and back, the driving synchronous belt wheel rotates to move along the synchronous belt, and therefore the trolley can walk on the track. The synchronous belt not only serves as a part of the driving device, but also restrains the walking trolley on the track, so that the trolley cannot fall off from the track. And meanwhile, the connecting position between the driving synchronous belt wheel and the synchronous belt is located in the trolley body, so that the trolley stably walks on the track. 本实用新型公开了一种轨道行走小车组件，包括行走小车、轨道；通过将沿轨道延伸方向延伸的同步带与行走小车内的主动同步带轮作为行走小车前后移动的驱动装置，通过主动同步带轮转动而沿着同步带移动，而使小车在轨道上行走。该同步带不但作为驱动装置的一部分，同时也将行走小车约束在轨道上，使小车不会与轨道脱落。同时，由于主动同步带轮与同步带之间的连接位置在小车车体内部，使小车稳定的在轨道上行走。
