Escalator and light step chain and application thereof

Abstract

The invention relates to the technical field of escalators, and particularly relates to an escalator and a light step chain and an application thereof. The escalator comprises a step chain and a guide rail, wherein the step chain moves on the guide rail. The step chain comprises a plurality of chain link units, and each chain link unit comprises a roller shaft, a roller, an outer chain piece and an inner chain piece. A first shaft hole is arranged on the outer chain piece, and a second shaft hole is arranged on the inner chain piece. The roller shaft penetrates through the roller, the first shaft hole and the second shaft hole cause the roller to be connected with the outer chain piece and the inner chain piece. The thickness of the outer chain piece is 4mm, the width of the outer chain piece is 35mm, and the pitch is 133.33mm. Compared with the prior art, the step chain has the advantages that the step chain can be applied to the escalator with a lifting height below 5m, the specification is smaller than that of the traditional step chain, materials can be greatly saved, and the manufacture cost of a complete machine is reduced.

Description

technical field [0001] The invention relates to the technical field of escalators, in particular to an escalator, a light step chain and an application thereof. Background technique [0002] Escalators are conveyors that are installed between floors of buildings to continuously carry people. Escalators are widely used in places where there is a concentrated flow of people, such as stations, docks, shopping malls, airports, and subways. [0003] The step chain of the escalator is the traction member of the escalator. When the step chain of the escalator meshes with the sprocket for transmission, all the load is carried by the teeth of the sprocket and the rollers on the chain. The use of rollers on the chain Please refer to the status figure 1 with figure 2 , the chain 1 includes several chain link units, and each chain link unit includes a roller shaft 3, a roller 2, an outer chain piece 11 and an inner chain piece 12, the outer chain piece 11 is provided with a shaft...

AI Technical Summary

Problems solved by technology

[0004] The first object of the present invention is to provide an escalator to solve the technical problem that the safety factor of the step chain of the existing escalator in the prior art is set too large, which leads to waste of materials and increases the production cost of the whole machine question

[0005] The second object of the present invention is to provide a light-duty step chain to solve the problem that the safety factor of the step chain of the existing escalator in the prior art is set too large, which leads to waste of materials and increases the production cost of the whole machine technical issues
