Description

Splicing oil pan structure and moving walkway

technical field

The invention relates to the technical field of escalators or moving walks, in particular to a spliced oil pan structure and moving walks.

Background technique

A moving walkway refers to a fixed electric drive device with a circular running (slab or belt) walkway for transporting passengers at a horizontal or inclined angle of no more than 12° (generally set horizontally, that is, a moving walkway with an inclined angle of 0° is called a horizontal automatic walkway. sidewalk). Moving walks are suitable for places with concentrated traffic such as stations, docks, shopping malls, airports, exhibition halls and gymnasiums. The step chain of the moving walk needs to be lubricated by dripping oil during use, and the step chain is a closed loop structure, and the lubricating oil will fall along with the chain on other parts of the escalator and the truss. Especially for outdoor moving walks, the dripping oil will mix with rainwater, causing water pollution and other environmental pollution. Therefore, an oil pan structure is usually provided on the truss of the moving walk for guiding and collecting lubricating oil of the step chain.

For the horizontal moving walk, its length is basically more than 30m. Due to the limitation of the site, the handling space and other conditions, the truss of the horizontal moving walk cannot be made into one, and must be manufactured and transported in sections. Therefore, the oil pan structure of the horizontal moving walk must also be divided into several sections for manufacturing and handling like the truss. When the trusses are spliced at the project site, the oil pan structure also needs to be spliced. For the multi-segment truss spliced to form a horizontal moving walkway, the two adjacent trusses are generally relatively horizontal, so there must be no gaps between the corresponding two adjacent oil pan structures to ensure no oil leakage. In the traditional technology, when splicing two adjacent trusses of a horizontal moving walkway, two adjacent oil pan structures are welded together, so as to cover the gap between the two adjacent oil pan structures, so as to Prevents oil from dripping from crevices. However, the above-mentioned structure needs to be welded at the engineering site, and the operation is complicated. Moreover, welding penetration and weld defects may occur during welding at the engineering site, which may lead to oil leakage from the oil pan structure.
