In this adjustment method, the width of the step unit has been determined, and it is impossible to adjust the step width arbitrarily within the width range specified by the national standard.
[0005] Some of the existing escalator step structures have a fixed width or some cannot be adjusted arbitrarily in the width range, so that the step structure cannot meet the requirements of escalators of all widths.

The invention discloses an adjustable-width escalator step structure and its self-adaptive adjustment device, comprising a fixed step, two adjustment steps installed on both sides of the fixed step, and a step linkage mechanism that drives the two adjustment steps to act synchronously and reversely and the loading mechanism that drives the action of the step linkage mechanism. The loading mechanism is fixed on the fixed step, and the step linkage mechanism is driven by the electric or manual driving of the loading mechanism, thereby driving the two adjustment steps to move synchronously and reversely on the inner side of the fixed step to realize Width adjustment of the entire cascade structure. The present invention adopts the cascade linkage mechanism to cooperate with the structure of the adjustable cascade and the fixed cascade, so that it can be adjusted within the width range of 0.58-1.10m specified by the national standard, and the cascade width can be adjusted at any size and the adjustment is more flexible, so that the cascade The structure meets all escalators of different sizes, and the adjustable steps are easy to disassemble and assemble, which is convenient for later maintenance.
Description
technical field [0001] The invention relates to parts of an escalator, in particular to an escalator step structure with adjustable width and an adaptive adjustment device thereof. Background technique [0002] According to the national standard GB16899-2011 "Safety Specifications for the Manufacture and Installation of Escalators and Moving Walks", the step width of escalators ranges from 0.58 to 1.10m; In 2.5 ~ 5mm. [0003] The steps of existing escalators are generally processed by one-piece casting process, and the width of the steps is fixed, which cannot be adjusted within the range of 0.58-1.10m stipulated by the national standard. At the same time, during the casting process of steps with different widths, it is necessary to To develop molds of different sizes, the production cost is higher. [0004] In order to adjust the step width, some companies divide the steps into several units, and the step units are fastened by bolts, and the step width is adjusted by inc...
