Aluminum alloy stair

Abstract

The invention relates to the field of escalators, in particular to a stair formed by die casting of aluminum alloy. The stair comprises a tread, a kicking plate and a triangular frame. The tread, thekicking plate and the triangular frame are formed by die casting of aluminum alloy. The triangular frame is provided with a driving wheel and a driven wheel. A semi-closed round installing groove is formed below the driving wheel. A plurality of antiskid teeth are evenly distributed on the upper surface of the tread. The antiskid teeth are square or triangular. The two ends of the upper surface ofthe tread are provided with an upper clamping head and an upper clamping groove correspondingly. The two ends of the lower surface of the tread are provided with a lower clamping head and a lower clamping groove correspondingly. Reinforcing ribs are arranged between the upper surface and the lower surface of the tread to divide a cavity of the tread into a plurality of equal parts. Separation plates are arranged at the ends close to the upper clamping head and the lower clamping head and are trapezoidal.

Description

technical field [0001] The invention relates to the field of escalators, in particular to an aluminum alloy die-casting formed step. Background technique [0002] The escalator is an open continuous transportation tool, which can transport 1000-1500 people per hour, and it can go up and down, and it can also be used as an ordinary staircase when the power failure or maintenance stops, which is very convenient. Therefore, it is widely used in densely populated places such as airports, stations, and docks. In every escalator, the aluminum alloy step tread is the most and the most important part. An escalator with a conventional lifting height of about 4500mm needs 55-62 aluminum alloy step pedals, while an escalator with a large lifting height needs as many as 80-110 aluminum alloy step pedals. Due to the large number of aluminum alloy step pedals, it is often Therefore, the quality of an escalator largely depends on whether the structural design of the aluminum alloy step p...

AI Technical Summary

Problems solved by technology

[0003] When installing the aluminum alloy steps currently on the market, it is necessary to fix the pedals and kick plates on the triangular frame, and the connection between the pedals needs to be fixed and installed through other components, such as screws, etc., so that the assembly and disassembly of the aluminum alloy steps Inconvenient, and the structural design is also complicated, which makes processing and production very inconvenient, and the comb structure is uniformly used throughout, so that the surface of the pedal has no concave-convex anti-skid effect, and it also causes waste of materials
