RU159263U1 - SANITARY EVACUATION RAIL PLATFORM - Google Patents

Abstract

A sanitary evacuation rail platform, consisting of a flat bearing part, to the lower plane of which four rail wheels are rigidly attached through brackets, characterized in that the flat bearing part of the platform is divided into two equally sized halves connected by hinges allowing them to be folded into the transport position while the main elements of both parts of the platform are made of composite materials, and the width of the platform in the folded position allows it to be placed on the steps of the escalator between its vertical fixed walls.

Description

The utility model (PM) relates to the field of rescue operations in case of technological disasters (accidents or terrorist attacks) in subway tunnels, in particular, for the evacuation of wounded and dead from places where access to special rescue vehicles is difficult or impossible according to local conditions.

Currently, the evacuation of the dead and wounded in the subway is carried out mainly with the use of a stretcher, which can be carried by 4 or 6 rescuers. At the same time, the movement of rescuers on the sleepers to the nearest platform, where doctors are located, is difficult and slow. As a result, a lot of valuable time is lost, especially in cases where this path can be hundreds of meters.

As the closest analogue of PM according to the patent DE 10143445 dated 03/27/2003 A1, a sanitary evacuation rail platform was adopted, consisting of a supporting part, to the bottom surface of which four rail wheels are attached, divided into two equally sized halves connected by hinges, allowing them to be manufactured folding into transport position [1].

The disadvantages of this model are significant weight, since it is made of metal. In addition, in the folded transport position, it is difficult to manually lower it down the steps of the escalator due to its considerable size and heavy weight.

The technical task of the PM is the creation of a sanitary evacuation rail platform (hereinafter - SERP) for transporting wounded and dead in technological disasters from the subway tunnels, which have less weight and dimensions when folded.

The technical problem is solved due to the fact that the SERP consists of a flat bearing part, to the lower plane of which four rail wheels are rigidly attached through brackets.

SERP differs in that the flat bearing part of the platform is divided into two equally sized halves connected by hinges, allowing them to be folded into the transport position. In this case, the main elements of both parts of the platform are made of composite materials [2], and the width of the platform in the folded position allows it to be placed on the steps of the escalator between its vertical fixed walls.

The design of the SERP and its elements are shown in the figure, where are indicated:

FIG. 1- view of the platform along the facade; FIG. 2 - end view of the platform; FIG. 3 is a view of the end face of the platform when folded; pos. 1 - bearing flat part of the platform; pos. 2 - wheel brackets; pos. 3 - wheels with flanges; pos. 4 - hinges; pos. 5 - rails; pos. 6 - soft handles; pos. 7 - sleepers; pos. 8 - hinge brackets 4.

Rail SERP is a movable rigid structure of a removable type, consisting of a supporting flat part of the platform 1, which can be folded in half for transportation due to the presence of hinges 4 with brackets 8.

Brackets 2 of the wheels 3 are rigidly attached to the lower plane of the elements 1. The platform is manually moved along the rails 5 by lifeguards. Carrying a folded sanitary evacuation rail platform (Fig. 3) is carried out by soft handles 6.

After delivery manually down the escalator of the folded platform to the place of use, it is lowered onto the rails 5 and opened to the working position (Fig. 1 and Fig. 2). If necessary, stretchers are installed on the platform.

Then the platform is manually rolled into the disaster zone, where the stretcher is loaded onto the platform with the dead and wounded, if any. The platform can also be used to transport victims of technological disasters on railways in tunnels and other places, access to which ambulance vehicles is not possible or difficult.

The platform with victims is being rescued by rescuers to the nearest metro station, where the medical staff is located.

The manufacture of SERPs from composites (glass or carbon fiber reinforced plastics) is carried out completely in workshop conditions.
