[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-3 The utility model provides a technical solution, a guide mechanism of a single-beam crane, comprising a track 1, a support frame 2, a driving wheel 3 and a driving motor assembly 5. Among them, vertical grooves 2.1 are respectively provided on the front and rear sides of the middle of the top surface of the support frame 2, a support wheel 4 is rotatably installed between the two side walls of the inner cavity of the vertical groove 2.1 on the rear side, and the driving wheel 3 is rotatably installed between the two side walls of the inner cavity of the vertical groove 2.1 at the front end, the driving motor assembly 5 is fixed to the front end of the outer wall of the support frame 2, and the power output shaft of the driving motor assembly 5 is fixedly docked with the central axis of the driving wheel 3. A connecting plate 2.2 is provided on the top of the rear end of the support frame 2, and the connecting plate 2.2 is used to be fixedly connected to the end of the bridge of the single-beam crane by bolts. The supporting wheel 4 and the driving wheel 3 are respectively supported on the top surface of the track 1, and the driving motor assembly 5 drives the driving wheel 3 to rotate, thereby realizing the longitudinal movement of the end of the bridge bearing the support frame 2.

[0026] The guide frame 6 is fixed to the front and rear ends of the support frame 2, and the two sides of the middle of the guide frame 6 are respectively provided with slide grooves 6.1.1, and the guide wheel assembly 8 includes a vertical shaft 8.1 with the top end slidingly clamped in the slide groove 6.1.1, a groove wheel 8.2 rotatably mounted on the bottom end of the vertical shaft 8.1, and a top block 8.3 fixed to the top end of the vertical shaft 8.1, and the annular grooves in the middle of the outer peripheral walls of the two groove wheels 8.2 are correspondingly clamped on the two side edges of the top of the track 1. Among them, the guide frame 6 includes a U-shaped plate frame 6.1 and a vertical plate 6.2 fixed to the middle of the U-shaped plate frame 6.1 and fixed to the front and rear end surfaces of the support frame 2 with bolts, and the slide grooves 6.1.1 are arranged on both sides of the middle of the bottom surface of the inner cavity of the U-shaped plate frame 6.1.
