Abstract

The invention relates to an interlocking device of a vehicle emergency escape system, which is characterized in that a rope is connected with a power device and an unlocking disc, the power device is connected with a door, when an emergency front door is opened, the power device connected with the door pulls the rope to drive the unlocking disc to rotate, and the unlocking disc leads a locking mechanism to be unlocked, thereby realizing interlocking of the front door and a escape ramp way. The power device is fixed on a movable component of the front door, and the unlocking disc is fixed on afixing base of the locking mechanism. The emergency front is opened to provide power, and the unlocking disc is pulled through the rope to unlock the emergency escape ramp way. When retracting, on the condition that the emergency front door is not closed, the escape ramp way can be locked normally without manual operation, and when the emergency front door is closed, the unlocking disc can automatically return to an original state. The interlocking device has the advantages that the interlocking device is high in opening efficiency and few in operation steps without manual operation, after the emergency front door is opened, the emergency front door is opened to provide the power to unlock the escape ramp way and form an escape passage, thereby increasing escape efficiency.

Description

technical field [0001] The invention relates to a linkage device in a vehicle emergency escape system, which belongs to the field of mechanical transmission machinery. Background technique [0002] Most rail vehicles are designed with emergency escape equipment at present, but the opening methods of the emergency escape ladders used for emergency escape are all manual, and the opening efficiency is low and inconvenient. Contents of the invention [0003] The invention proposes a linkage device in a vehicle emergency escape system, and aims at solving the linkage between a door and an escape ramp in the vehicle emergency escape system. The emergency escape ramp is unlocked by pulling the unlocking disc through the rope. [0004] The technical solution of the present invention: it is characterized in that the power device connected with the door and the unlocking disc are connected by a rope, when the emergency front door is opened, the power device connected with the door ...
