A general-purpose escape system for subway locomotives

Abstract

The invention relates to the technical field of escape systems, in particular to a universal type escape system for a subway locomotive. The universal type escape system for the subway locomotive is applied to the condition that passengers safely escape to the subway track surface from the interior of a train through operation of a driver or the passengers when the subway train is in an emergency state. The universal type escape system for the subway locomotive mainly comprises a seal frame, a door page, a connecting rod mechanism and a lock mechanism; the seal frame and the connecting rod mechanism are both fixed on a locomotive body; the connecting rod mechanism is located at the back end of the door page; the lock mechanism is integrally installed on the upper portion of the inner side of the seal frame; under the action of the connecting rod mechanism, the door page simultaneously does composite type motion of horizontal moving and turning in the opening process; the door page automatically turns to be opened after being pushed by operation personnel; when the door page is folded into the seal frame, the lock mechanism automatically locks the door page. According to the escape system, the weight is smaller, the occupied space is smaller, the opening action of the door page is simple, horizontal moving and turning of the door page are completely achieved through one action, the folding speed is higher, a large amount of folding time is saved, the structure is simple, the reliability is high, the passing width is large, and meanwhile it can be guaranteed that the escape system is suitable for various locomotive types.

Description

technical field [0001] The invention relates to the technical field of escape systems, in particular to a general-purpose escape system for subway locomotives, which is operated by drivers or passengers to enable passengers to safely escape from passenger cars to the subway rail surface in emergency situations. Background technique [0002] At present, there are many kinds of downward-turning escape doors in the escape systems on the market. Such as: China Authorized Invention Patent: Publication No. 103241251A, Publication Date August 14, 2013, Application No. 201310154349.6, Application Date April 27th, 2013 A ramp-type emergency evacuation door for subway locomotives; Chinese Authorized Invention Patent: Publication No. 101062686, Publication Date October 31, 2007, Application Number: 200610076658.6 Application Date: A subway locomotive escape door device disclosed on April 28, 2006. [0003] The above-mentioned escape system includes a door frame and an outward-turning ...

AI Technical Summary

Problems solved by technology

Since the door leaf is directly hinged on the door frame, the final position of the door leaf after turning over is affected by the position of the coupler, so the escape doors in these escape systems are only suitable for models with a relatively gentle front shape. Increased thickness, interference with the coupler after turning over

At the same time, because the front end of the flipped door leaf is hinged with a secondary flip pedal and the linkage handrails are provided on both sides, the whole mechanism is complicated and the reliability is reduced.
