Escalator stair packaging method

Abstract

The invention relates to an escalator stair packaging method, which comprises the following steps of putting an integral isolation frame (220) at the inner side of an upwards and downwards turning first stair (100); sleeving a second stair (200) with the opposite upward and backward facing direction and the opposite forward and backward facing direction to the first stair onto the isolation frame. The isolation frame is in a tube shape with two narrow walls (220a) and two wide walls (220b). In the step of putting the isolation frame, the two narrow walls are inserted into the two triangular support frames (106) of the first stair, and the two wide walls are inserted into a position between a front cross beam (108) and a back cross beam (110). In the step of upwards sleeving the stairs, the two narrow walls are inserted into a position between the two triangular support frames (206) of the second stair; the two wide walls are inserted into a position between a front cross beam (208) and a lower cross beam (210). Under the supporting effect of the isolation frame, a separation state is formed between the two stairs; the contact of the two stairs can be prevented, so that the stable overlapping package can be realized.

Description

technical field [0001] The invention relates to a packaging method for escalator steps. Background technique [0002] As disclosed in the Chinese Patent Publication CN2880770Y, the escalator steps are generally composed of pedals, kick plates and tripods (main frame). Among the steps, there are separate assembled steps that are assembled by assembling these parts that are manufactured separately, and there are also integral steps that are integrally formed by integral die-casting. Regardless of its manufacturing method, the formed steps have a triangular or approximately triangular structure when viewed from the side. This structure makes it difficult for the steps to overlap each other stably during packaging, and it is difficult to effectively use the packaging space. Of course, a large amount of cushioning materials such as packaging foam can be filled between the steps to realize the overlapping packaging of the steps, but filling the cushioning materials not only adds...

This structure makes it difficult for the steps to overlap each other stably during packaging, and it is difficult to effectively use the packaging space

Of course, a large amount of cushioning materials such as packaging foam can be filled between the steps to realize overlapping packaging of the steps, but filling the cushioning materials not only adds a greater burden to the packaging process, but also causes environmental pollution when the used cushioning materials are disposed of
