Stopping device used for metro overall height sliding door

Abstract

The invention discloses a stopping device for a metro overall height sliding door. The stopping device for the metro overall height sliding door comprises a mounting support, a stopping seat which is fixed on the mounting support and used for stopping the sliding of a door leaf and an inductive switch which is fixed on the mounting support and used for determining that the door leaf is in a full open position or a full closed position, wherein the stopping seat is provided with a through sliding groove and a lifting rod which slides along the length direction of the sliding groove along the sliding direction of the door leaf. When the door leaf is in the full open position or the full closed position, an contacting end of the lifting rod is driven to slide along the sliding groove by the door leaf which slides towards the stopping seat, a connecting status or a disconnecting status of the inductive switch is changed by an lifting end of the lifting rod, and an elastic part which is used for the restoration of the lifting rod when the door leaf is far away from the stopping seat is arranged on the mounting support or the stopping seat. According to the stopping device for the metro overall height sliding door, the inductive switch and the stopping seat are combined into a whole, impact force from the sliding door is received by the stopping seat to avoid the impact force impacting the sensing switch, so that the service life of the switch is prolonged, the dual functions of stopping and transmitting the information that the door leaf is in a open status or a closed status are achieved, and the advantage of being convenient to mount and adjust is achieved.

Description

technical field [0001] The invention relates to the technical field of subway screen doors, in particular to a stop device for full-height sliding doors of subways. Background technique [0002] The subway screen door is an essential facility for modern subway projects. It is set along the edge of the subway platform to isolate the train from the waiting room of the subway platform. The installation of screen doors in the subway can not only prevent passengers from falling or jumping off the track and cause danger, but also allow passengers to take the subway safely and comfortably. The exchange of hot and cold air between the operating areas reduces the operating energy consumption of the environmental control system, thereby saving operating costs. [0003] Subway screen doors include sliding doors corresponding to the doors of subway vehicles and fixed doors corresponding to other parts of subway vehicles. Every time a subway vehicle enters a station, all sliding doors a...
