Installation structure for safety door rolling wheels
An installation structure for safety door rolling wheels comprises the rolling wheels, a rolling wheel guide rod and a safety door. The rolling wheels are fixed to the safety door. The rolling wheel guide rod is fixed to a device. The rolling wheels and the rolling wheel guide rod are assembled in a linear movement manner so that the safety door can slide in a reciprocating manner. The installation structure is characterized in that the number of the rolling wheels is more than one, one part of the rolling wheels are vertically and symmetrically assembled at one end of the rolling wheel guide rod; the other part of the rolling wheels are assembled on the upper side of the middle of the rolling wheel guide rod; no rolling wheels are assembled on the lower side of the middle of the rolling wheel guide rod; and the safety door force bearing manner is a cantilever beam force bearing manner. A safety door force diagram is established by applying theoretical mechanics, and the rolling wheel installation structure is reasonably arranged according to force bearing analysis, wherein the two corresponding rolling wheels are vertically and symmetrically arranged at one end of the rolling wheel guide rod, the two or more corresponding rolling wheels are assembled on the upper side of the maximum force bearing point side by side, and no rolling wheels are assembled on the lower side of the maximum force bearing point. Compared with a traditional structure, under the same use condition, rolling wheel abrasion can be reduced, the service life of the rolling wheels can be prolonged, stability of the safety door can be improved, and the use cycle of the safety door is prolonged.
