Overall high safety door without upper supporting

Abstract

The invention relates to an overall height type safety door without a support at the upper part used for a metro elevated platform, a railway platform, an automobile platform. The connection with any device not required by the upper part of the overall height type safety door is solved through increasing an upright column cross section. The structure comprises a fixed door / an emergency door, a sliding door, a threshold, a top box, a cross beam, a load supporting driving mechanism, a bottom support and a upright column, wherein, the lower part of the fixed door / the emergency door is arranged on the threshold and the bottom support, the upper part of the fixed door / the emergency door is arranged on the device of the top box, the threshold is installed on the bottom support, the sliding door is installed on the load supporting driving mechanism at the lower part of the cross beam in a hanging way. The present invention has the advantages that because the section size of the upright column is big enough, the whole bearing structure holding a enough strength can be guaranteed, therefore to realize that the upper part of the overall height type safety door requires no connection with any device, under the function of a combined load, the integrated deformation of the overall height type safety door does not exceed a specified value, the normal operation is guaranteed, and the present invention has the characteristics of simpleness and reliability.

Description

technical field [0001] The invention relates to a full-height safety door without upper support for elevated subway platforms, railway platforms and bus platforms. The utility model belongs to the technical field of safety doors. Background technique [0002] Safety doors can be seen everywhere in our lives, and safety doors mainly include half-height safety doors and full-height safety doors. The clear height of the full-height security door is 2-2.2m, and the clear width is 1.8-2m. The height of the half-height safety door is 1.2-1.5m, and the clear width is 1.8-2m. Due to the limitations of the installation space and interface of the full-height safety door, there will be no connection structure on the upper part of the full-height safety door. At present, such safety door systems at home and abroad often use a large connecting structure installed on the upper part to connect with the original steel frame structure of the platform or connect the load-bearing structure ...

Problems solved by technology

Due to the limitations of the installation space and interface of the full-height safety door, there will be no connection structure on the upper part of the full-height safety door

At present, such safety door systems at home and abroad often use a large connecting structure installed on the upper part to connect with the original steel frame structure of the platform or connect the load-bearing structure with an additionally installed steel frame structure, which has defects such as complex structure and high cost.
