In the embodiment, since the rolling surface 21a of the first roller 21 is vertically attached to the upper surface of the lower rail 3 and bears most of the weight of the entire moving assembly 10, the first roller 21 is configured as a driving wheel, which can effectively avoid the occurrence of a slip, and correspondingly, the second roller 22 is a driven wheel to roll under the driving of the first roller 21. Because the utility model discloses a rolling surface 22a of first gyro wheel 21 and second gyro wheel 22 need not to set up the annular groove among the prior art again, consequently first gyro wheel 21 and second gyro wheel 22 all can adopt the form of rubber coating wheel. Compared with steel wheels adopted in the prior art, the rubber-covered wheel has better shock absorption performance and can effectively relieve abnormal sound generated when the moving assembly 10 walks along the guide rail.
In addition, each pair of second rollers 22 may include at least one adjusting roller, the adjusting roller has a roller adjusting mechanism 221 connected to a roller body thereof, and the roller adjusting mechanism 221 is configured to adjust a distance between a rolling surface 22a of the adjusting roller and a surface of the lower rail 3, so that the two second rollers 22 can be better attached to the lower rail 3, and a gap between the second rollers 22 and the lower rail 3 is avoided, which affects normal use of the moving assembly 10. Preferably, the roller adjusting mechanism 221 has a function of elastic adjustment, that is, an elastic member such as a spring is connected to a rotating shaft of the adjusting roller, so that the adjusting roller applies pressing force to the surface of the lower rail 3 through the elastic member to ensure that the adjusting roller can be attached to the surface of the lower rail 3 under any condition.
Both sides of the lower rail 3 have first limiting portions 31 extending along the length direction of the lower rail 3 (i.e. the direction perpendicular to fig. 3), the first limiting portions 31 are disposed at both sides of the lower rail 3, and the two second rollers 22 are respectively located below the first limiting portions 31 at the same side.
The first limiting part 31 is arranged on the lower guide rail 3 to further limit the position of the second roller 22, and particularly, the first limiting part 31 is used as the upper limiting part of the second roller 22, so that the lower traveling mechanism 2 cannot be separated from the lower guide rail 3 along the vertical upward direction, the use safety and the stability of the moving assembly 10 are further improved, and the derailment condition is completely avoided. In this embodiment, the upper surface of the first limiting portion 31 extends to the upper surface of the lower rail 3, that is, the upper surface of the first limiting portion 31 is flush with the upper surface of the lower rail 3, and by this structural arrangement, the upper surface area of the lower rail 3 can be increased, so that the rolling contact area between the first roller 21 and the lower rail 3 can be correspondingly increased.
The two sides of the lower rail 3 are further provided with second limiting parts 32 extending along the length direction of the lower rail 3, the second limiting parts 32 are also arranged at the two sides of the lower rail 3, and the two second rollers 22 are respectively located above the second limiting parts 32 at the same side.
In addition, as shown in fig. 2 and 4, the upper traveling mechanism 5 of the moving assembly 10 is connected to the top of the support 1 and horizontally moves on the upper guide rail 4, the upper guide rail 4 is disposed parallel to the lower guide rail 3, so that the entire upper traveling mechanism 5, the entire lower traveling mechanism 2, and the support 1 can horizontally move in the direction of the guide rails, and the upper and lower ends of the support 1 are directly connected to the guide rails, thereby improving the stability of the entire moving assembly 10.
