Problems solved by technology
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 needs of escalators of all widths.

Embodiment Construction
[0030] The present invention will be described in further detail below in conjunction with accompanying drawing, but is not the restriction to protection scope of the present invention.
[0031] Such as figure 1 and 2 As shown, an escalator step structure with adjustable width includes a fixed step 1, an adjustable step 2, a step linkage mechanism 4, and a loading mechanism 6.
[0032] Such as figure 1 and 3 As shown, the fixed step 1 includes a tread 101, a support plate 102, a connecting plate 103 and an outer baffle 104.
[0033] Such as figure 1 and 4 As shown, the adjustment step 2 includes an adjustment pedal 204 and an inner baffle 205 fixed on the front side of the adjustment pedal 204 and a triangular frame 201 connected between the adjustment pedal 204 and the inner baffle 205. The main wheel seat 202 and the auxiliary wheel seat 203 used in conjunction with the wheel and the auxiliary wheel of the escalator respectively; two adjustment steps 2 are respectively...

The invention discloses a width-adjustable escalator step structure and a self-adaptive adjusting device thereof. The width-adjustable escalator step structure comprises a fixed step, two adjusting steps installed on the two sides of the fixed step, a step linkage mechanism for driving the two adjusting steps to synchronously and reversely act, and a loading mechanism for driving the step linkagemechanism to act, wherein the loading mechanism is fixed to the fixed step, the loading mechanism is driven electrically or manually to drive the step linkage mechanism to act, therefore the two adjusting steps are driven to synchronously and reversely act on the inner side of the fixed step, and width adjustment of the whole step structure is achieved. According to the width-adjustable escalatorstep structure and the self-adaptive adjusting device thereof, by adopting the structure that the step linkage mechanism matches with the adjusting steps and the fixed step, the step width can be adjusted within the width range of 0.58-1.10 meters specified by the national standard, and the width of the steps with any sizes can be adjusted freely and more flexibly, so that the step structure meetsthe requirements of all escalators of different sizes, the adjusting step is convenient to disassemble and assemble, and the later maintenance is facilitated.
Description
technical field [0001] The invention relates to a component of an escalator, in particular to an adjustable-width escalator step structure 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. The width of the steps is fixed and cannot be adjusted within the range of 0.58-1.10m specified 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 increasing...
