Escalator

Abstract

The invention relates to an escalator. The escalator is provided with a truss (2), a plurality of stairs (5), a plurality of guide rails (13, 14, 15 and 16) and an oil receiver (17), wherein the truss (2) is arranged on a building, the stairs (5) are annularly connected through a stair chain and circularly move in the truss, the guide rails (13, 14, 15 and 16) guide the stairs, and the oil receiver (17) is arranged in the truss and receives lubricating oil dropping down from the stair chain. The escalator is characterized by further comprising an oil guide component (24), wherein the oil guide component (24) is arranged in the transition range from a lower curve section to a lower horizontal section of the main wheel operating guide rail (13), located below the main wheel operating guide rail and located above the auxiliary wheel operating guide rail (14). The oil guide component receives lubricating oil dropping down from the main wheel operating guide rail and guides the lubricating oil into the oil receiver from the outer side of the left side or the right side of the moving direction of the stairs. Thus, the escalator can effectively prevent stair pollution caused by dropping of the lubricating oil accumulated in the transition range from the lower curve section to the lower horizontal section of the main wheel operating guide rail.

Description

Technical field [0001] The invention relates to an escalator. Background technique [0002] Step pollution caused by dripping of lubricating oil on the step chain often occurs on escalators. As a technique to prevent such pollution, Japanese Patent Application Publication No. 2011-73837 has the following description: "A passenger conveying equipment having: a truss installed in a building and provided at both ends in the longitudinal direction An entrance and exit floor flush with the floor of the building; steps, a plurality of the steps are connected by a step chain in a ring shape, and circulates in the truss; guide rails are arranged on the truss to guide the steps , Characterized in that: it also has an oil guide plate, the oil guide plate is arranged below the fixed part that fixes the running rail on the truss, the oil guide plate will drip from the step chain to the guide rail and then from the guide rail The lubricating oil is induced to return to the outside of the st...

AI Technical Summary

Problems solved by technology

The lubricating oil accumulated in this area drips on the return step, which will cause the contamination of the step

However, the prior art disclosed in the above-mentioned patent bulletin cannot prevent the cascade pollution caused by the dripping of lubricating oil accumulated in the transition range from the lower curved section to the lower horizontal section of the main wheel running guide rail.
