Prevent foreign objects from entering the steps of the escalator

Abstract

The invention discloses a stair capable of preventing foreign bodies from entering an escalator. The stair comprises a plurality of racks, first baffles and second baffles, wherein the racks are equidistantly arranged on the treading surface of the stair in a protruding mode; each first baffle is transversely arranged on the sidewall of one rack of every two racks; each second baffle is transversely arranged on the sidewall of the other rack of every two racks; the widths of all the baffles are consistent; and the upper surfaces of the first baffles and the lower surfaces of the corresponding second baffles are overlapped. According to the stair, the two overlapped baffles are arranged at the upper end of the space between every two adjacent racks to prevent the foreign bodies from entering the lower end of the space between the two racks. When the stair intersects with comb plates, comb teeth can automatically separate the two overlapped baffles between every two adjacent racks without affecting normal running of the escalator, and accordingly the technical problem that the foreign bodies are liable to enter the spaces between the racks of the stair and accordingly cause running failure or accidents of the escalator is effectively solved.

Description

technical field [0001] The present invention relates to an escalator, and more particularly, the present invention relates to a step that prevents foreign objects from entering the escalator. Background technique [0002] In addition to the great convenience brought by the escalator (moving sidewalk), accidents often occur. The step treads of the existing escalator are provided with racks at intervals. At the entrance and exit of the steps, the rack is meshed with the comb teeth of the comb plate installed at the entrance and exit. The meshing depth of the rack and the comb teeth is not less than 6mm. That is to say, the height of the rack is not less than 6mm. [0003] During normal operation, some objects are easy to fall on the step tread. If there is a foreign object between the step teeth, it will run to the comb along with the steps. The junction is constantly rolling. If the foreign matter rolls under the teeth of the comb plate, as the steps run, the foreign matter...

Problems solved by technology

[0005] Another purpose of the present invention is to solve the problem that foreign objects are easily stuck between the teeth of the above step treads and cause the escalator to malfunction. The present invention adopts two mutually superimposed blocking plates at the upper end of the teeth to prevent foreign objects from entering the lower end of the teeth. When the step intersects with the comb plate, the comb can automatically cut off the two superimposed blocks, which does not affect the normal operation of the escalator, and effectively solves the technical problem that foreign objects are easy to enter between the step teeth and cause the escalator to fail or cause accidents.
