Description

Technical Field

[0001] The utility model relates to a traveling mechanism, in particular to a traveling mechanism applied on a guide rail and used for realizing the forward movement of a vehicle. Background Art

[0002] The assembly line is used to realize the long-distance transportation of goods. When realizing the transportation of goods, it is necessary to use a carrier to clamp or hold the goods. For large places, such as supermarkets, under normal circumstances, the goods in the supermarket are placed in various places according to categories. When selling online, it is necessary to use the assembly line set up in the supermarket to collect the goods ordered by users online to the background for unified and centralized packaging and distribution. In the application place, it is necessary to set up a guide rail to communicate with various areas in the place. A plurality of carriers need to be set on the guide rail, and the carrier is used to transport the items to be transported. To realize the transportation of the carrier, it is also necessary to set a power mechanism along the direction of the guide rail. The power mechanism is adapted to the setting position of the guide rail, and the power mechanism is used to push the carrier on the guide rail. A hanging structure is set at the upper end of the carrier, and the hanging structure is movably hung on the guide rail. The power mechanism generally directly pushes the hanging structure to make the carrier move forward on the guide rail. The hanging structure can be a hook, a roller or a walking trolley. It can be a structure in which a push pin or a bird hook is set on the power mechanism to realize the promotion of the hanging structure, or a protruding push pin structure is set on the walking trolley to receive the driving force of the push block in the power mechanism to realize the forward movement of the vehicle on the guide rail. The existing trolley is generally provided with a push pin, which indicates that the application of a specific trolley can only receive the power given by the power mechanism from one side of the guide rail. The application of the guide rail in the venue will be limited by the specific internal structure of the venue. Sometimes, the trolley cannot adapt well to the relative position setting between the power mechanism and the guide rail. Therefore, it is generally necessary to reserve trolleys of several specifications, which will bring pressure to the equipment management of the manufacturer. Utility Model Content
