城市轨道交通站台屏蔽门用应急解锁装置

Abstract

本实用新型涉及轨道交通屏蔽门技术领域，尤其涉及城市轨道交通站台屏蔽门用应急解锁装置，包括固定座和滑设于其内部的活动支架，活动支架一端连解锁杆、另一端设复位机构；固定座一侧通过转轴连钥匙锁与曲柄，曲柄可推动活动支架上的限位柱实现站台侧解锁；固定座另一侧滑设防护外壳，防护外壳上活动装设有带弹性复位件的定位件，定位件插入活动支架的定位孔后可带动其移动实现轨道侧解锁。本装置以紧凑的防护外壳与定位件替代大体积手柄，减少轨道侧空间占用，且定位件非使用时自动分离、防护外壳需滑至指定位置操作，能杜绝误触风险；两侧解锁独立高效，适配轨道交通站台高安全、高可靠的应急解锁需求。

Claims

A first sliding hole (101) is provided on the side wall of the fixed base (1) to accommodate the up and down movement of the positioning member (8). An elastic reset member (9) is provided inside the protective shell (7) to push the positioning member (8) to separate from the positioning hole (202).

2. The emergency unlocking device for a platform screen door of urban rail transit according to claim 1, characterized in that: The fixed base (1) is a tubular structure with both ends connected, and the movable bracket (2) is slidably installed inside the fixed base (1).

3. The emergency unlocking device for a platform screen door of urban rail transit according to claim 2, characterized in that: The movable bracket (2) has a limiting post (201) fixed on the side away from the protective shell (7). The fixed seat (1) is provided with a second sliding hole (102) to accommodate the sliding of the limiting post (201) up and down. The limiting post (201) extends through the second sliding hole (102) to the outside of the fixed seat (1). The side of the fixed seat (1) near the limiting post (201) is provided with a crank (5) rotatably mounted on a rotating shaft (6). The rotating shaft (6) is connected to a key lock to drive the crank (5) to rotate. The crank (5) then pushes the limiting post (201) to move upward along the second sliding hole (102).

4. The emergency unlocking device for a platform screen door of urban rail transit according to claim 1, characterized in that: The reset mechanism (4) includes several guide rods (401) fixed to the bottom of the movable bracket (2), a limiting plate (402) fixed to the bottom of the guide rod (401), and a spring (403) sleeved on the outside of the guide rod (401). The top of the spring (403) abuts against the bottom of the fixed seat (1), and the bottom of the spring (403) abuts against the limiting plate (402).

5. The emergency unlocking device for a platform screen door of urban rail transit according to claim 1, characterized in that: The positioning component (8) includes a plug-in positioning part (801), a connecting rod (802), and a limiting part (803) that are connected and fixed in sequence. The plug-in positioning part (801) is located on the outside of the protective shell (7), and the width of the plug-in positioning part (801) is adapted to the width of the first sliding hole (101). The plug-in positioning part (801) is adapted to the positioning hole (202) and is used to drive the positioning component (8) and the movable bracket (2) to slide up and down synchronously. The limiting part (803) is slidably disposed on the protective shell (7) along the thickness direction of the movable bracket (2). Inside the shell (7), the connecting rod (802) is used to connect the insertion positioning part (801) and the limiting part (803), and the protective shell (7) is provided with a through hole to accommodate its back and forth movement along the thickness direction of the movable bracket (2). The outer wall of the protective shell (7) is provided with a pressing opening (701) of the pressing positioning part (8). The elastic reset part (9) is sleeved on the connecting rod (802) inside the protective shell (7) and is used to push the limiting part (803) to move and reset to the side away from the positioning hole (202).

6. The emergency unlocking device for platform screen doors in urban rail transit stations according to claim 5, characterized in that: The limiting part (803) is provided with a groove (8031) near one side of the pressing opening (701).

7. The emergency unlocking device for a platform screen door of urban rail transit according to claim 1, characterized in that: An installation part (10) is arranged on the outer side wall of the fixing seat (1).
