Description
Technical field
The invention belongs to hitch switching device fields, and in particular to a kind of shunter anticreep hitch switching device and vehicle
Hook anti-dropout control method.
Background technology
Shunter refers to for train marshalling list, the locomotive for disintegrating, turning the shunting services such as line and vehicle taking sending.Work characteristics
It is continually to start and stop.
Shunter is the basic motive of work of shunting, and is technically required with the train locomotive of general tractor-trailer train
It is different.Since needs start traction or push vehicle group in short distance, therefore higher desin speed is not needed, but needed centainly
Tractive force, due to need often move forward or back, therefore require have it is good watch from a height or a distance condition, due to the mainly operation in station, need
By the curve of small radii, therefore the inflexible wheel base of locomotive is required to want small, due to being frequently necessary to starting and stopping vehicle.Therefore locomotive is required to grasp
Vertical flexible, braking ability is good, due to often in night work, lamp lighting requirement good brightness end to end；Furthermore it is required that convenient adjust
Vehicle personnel safety is got on or off the bus etc..
But the hitch switching device on existing shunter（Such as patent CN201320400870.9）In connection
The connection being susceptible between hitch and hitch rotating device loosens, and the problem of falling off, there are great security risks.
