Hydraulic vertical rotation type anti-flooding protective air-tight door for rapid rail traffic engineering

Abstract

The invention relates to a hydraulic vertical rotation type anti-flooding protective air-tight door for rapid rail traffic engineering, and belongs to the technical field of protective air-tight doors. The door includes a door leaf, a door frame, a hinge, a blocking mechanism, a hydraulic driving device and an electric control system; the door leaf is connected with the door frame on one side through the hinge, one side of the door leaf is provided with the blocking mechanism, and the door leaf is connected with the hydraulic driving device; the hydraulic driving device is connected with the electric control system, the hydraulic driving device includes a base, a hydraulic cylinder, a first driving arm, a second driving arm, a rotating shaft and a supporting arm. According to the door, the requirement of the rail traffic large space vertical rotation type air-tight door for self weight and hydraulic door closing force are well met, so that the hydraulic driving device can be synchronously started and shut off, the situation that the air-tight door has uneven stress since upper driving force and lower driving force are different is prevented, and the door has good application prospects.

Description

technical field [0001] The invention relates to a hydraulic vertical rotation type anti-flooding protective airtight door for rapid rail transit engineering, belonging to the technical field of protective airtight partition doors. Background technique [0002] The vast majority of urban rail transit systems are used to carry passengers commuting in the city, and in many cases urban rail transit systems will be regarded as the backbone of urban traffic. In times of war (such as World War II), underground railways were also used as factories or air-raid shelters. The subway systems of many countries (such as South Korea) have considered the possibility of war in the design, so whether it is the depth of the railway or crowd control, it also takes into account the needs of daily transportation and national defense. [0003] The subway project is usually an urban underground traffic artery, and it is an urban civil air defense evacuation artery, a material storage warehouse, a ...
