Description
Technical field
The utility model relates to the utility model to belong to railway construction technical field, and in particular to a kind of tunnel internal protection
The worm and gear link type locking used on door (Dong Shimen).
Background technique
Tunnel is the building channel of automobile or train passage.The cavern of place apparatus is usually provided in tunnel, tunnel is anti-
Shield door (Dong Shimen) be with fire prevention, antiknock, resist positive and negative wind pressure caused by train periodicity Piston Action Wind, prevent and treat equipment damage and
The door of support personnel's safety and the specific use of setting.Tunnel protection door (Dong Shimen) is applied in railway tunnel, such as transverse passage-way, respectively
Class equipment (ventilation, communication, electric power etc.) cavern, emergency relief war, emergency exit, sanctuary, vertical shaft incoming tunnel, inclined shaft access
In the caverns such as tunnel, repeater, substation.
Disclosed in Chinese patent CN106224003 it is a kind of for tunnel protection door or cavern door bivalve door, described
It is provided with the locking of pinion and-rack connecting rod on bivalve door, but is found during application, due to tunnel protection door or cavern
The connecting rod of door is longer and heavier, therefore the locking of pinion and-rack deposits and is not easy to control above-mentioned connecting rod, and rack-and-pinion
It is latched no self-locking function, connecting rod latching member is easy lower under gravity slip after locking.Moreover, above-mentioned link type is closed
Lock also lacks fixed device, can arbitrarily open after being latched locking, people without fixed duties etc. can arbitrarily carry out cavern.If train is expert at
