In addition, it should be noted that all the bolts are placed at and are connected with the platform through thin steel ropes, and the bolts and the platform are integrated without being stored separately, so that the bolts are prevented from being lost and are convenient to use.
It should be noted that, when folding, the two flat plates 14 need to be moved to be flush with the two support plates 1, and then folded together with the two support plates 1.
In addition to the above embodiment, the two panels 14 may be removed for separate placement when folded, but this takes up a lot more space than the above solution.
The assembly process of the invention is as follows:
taking the scheme that the escalator is positioned at one side of one supporting plate 1 as an example:
when the two flat plates 14 are unfolded, firstly, the two support frames 2 and the two support plates 1 are unfolded to form a platform, and meanwhile, the heights of the two flat plates 14 can be adjusted according to requirements; then, fixing the cross beam 7 at one side of the corresponding support plate 1, and unfolding the escalator; finally, the height of the plurality of support feet 10 can be adjusted as desired, thereby adjusting the height of the entire platform.
When the escalator is folded, the cross beam 7 is detached from the support plates 1, then the two support plates 1 and the two support frames 2 are folded and folded according to the mode, and finally the cross beam is fixedly connected to one side of one support frame 2 and is folded.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
