upper rollers

3, 32 or 36 lower rollers 4 (the number of the upper roller 3 and the lower roller 4 is 32), compared with two rollers as a set of machine type, equivalent to the cancellation of all limiting wheels, the processing and assembling cost is greatly reduced, compared with a roller as a set of machine type or roller type, the number of the limiting wheels is reduced by half, and the processing and assembling cost is obviously reduced. Because the shuttle does not have a shuttle wheel, the mass of the existing shuttle wheel accounts for about 7 percent of the mass of the shuttle, the quality of the shuttle is reduced, and the energy consumption of the operation of the shuttle can be reduced by at least 7 percent. The shuttle-free wheel on the shuttle body 5 means that the shuttle body 5 is not provided with a wheel which is matched with the upper and lower tracks of the door circle in a rolling way, but can be provided with a propelling wheel for propelling the shuttle to run.

Therefore, the outer side of the upper door ring 1 is generally an arc surface, in order to facilitate the installation of the upper roller 3, the lower side of the outer ring of the upper door ring 1 is provided with an upper installation surface 101, the upper roller 3 is installed perpendicular to the upper installation surface 101 through an upper core shaft 31, in the same way, the outer side of the lower door ring 2 is also generally an arc surface, in order to facilitate the installation of the lower roller 4, the upper side of the outer ring of the lower door ring 2 is provided with a lower installation surface 201, and the lower roller 4 is installed perpendicular to the lower installation surface 201 through a lower core shaft 41. Considering that the upper roller 3 and the lower roller 4 are convenient to replace, the upper mounting surface 101 and the lower mounting surface 201 are respectively arranged on the outer ring of the upper door ring 1 and the outer ring of the lower door ring 2, and workers can replace the upper roller 3 and the lower roller 4 from the outer sides of the upper door ring 1 and the lower door ring 2 more conveniently than the prior art which needs the workers to extend into the door rings.
